This framework covers the demand math, the hidden costs, and the decision criteria for each.","\u003Cp>When an EOL notice lands with a last-time-buy (LTB) deadline, a BOM owner has exactly three options: buy enough parts to cover the product for the rest of its life, buy a smaller bridge quantity while qualifying a replacement, or commit to a redesign and buy only what carries production to the changeover. Everything else is a variation of these three.\u003C\u002Fp>\n\u003Cp>The single question that separates them is this: how long must this design keep shipping, and can a qualified alternate realistically be ready before purchased stock runs out? If the product is near the end of its own life, a stockpile is usually cheapest. If a credible alternate exists and qualification is a matter of months, a bridge buy keeps cash free. If the part is one of several aging components on the same board, redesign often wins on total cost even though it looks most expensive up front.\u003C\u002Fp>\n\u003Cp>This article gives you the inputs to gather, the honest cost picture for each option, a worked sizing example, and a decision table. For what triggers this decision and how to read the notice itself, see \u003Ca href=\\\"\u002Fresource\u002Fproduct-news\u002Fnrnd-vs-eol-vs-obsolete-bom-actions\u002F\\\">NRND vs EOL vs Obsolete: What BOM Owners Should Do at Each Stage\u003C\u002Fa>.\u003C\u002Fp>\n\u003Ch2>Quick Answer: How to Choose\u003C\u002Fh2>\n\u003Cp>Choose a lifetime stockpile when remaining product life is short or fixed (roughly one to three years), demand is predictable, and no redesign budget exists. Choose a bridge buy when a realistic alternate has been identified and the qualification timeline is shorter than the stock the bridge quantity provides. Choose redesign when product life is long, demand is uncertain, the LTB cash requirement is large, or the board carries multiple at-risk parts that would each need their own stockpile.\u003C\u002Fp>\n\u003Cp>All three options require the same demand inputs, so gather the data before debating the strategy.\u003C\u002Fp>\n\u003Ch2>Inputs You Need Before Any Math\u003C\u002Fh2>\n\u003Cp>An LTB quantity is only as good as its inputs.

Moisture-sensitive devices stored outside proper dry conditions require rebaking per JEDEC J-STD-033 handling practices before reflow, and some customers refuse date codes older than two or three years regardless of storage quality. A five-year stockpile plan that ignores date-code policy is a plan to scrap parts.\u003C\u002Fp>\n\u003Ch2>Option 1: Lifetime Stockpile\u003C\u002Fh2>\n\u003Cp>A lifetime stockpile buys the full remaining-life demand in one order before the last order date. It wins when the product’s end is visible and the total quantity is affordable: end-of-life industrial products with support contracts, low-volume equipment with fixed service obligations, or any case where redesign cost clearly exceeds the buy.\u003C\u002Fp>\n\u003Cp>The unit price on the purchase order is not the cost of this option. Add carrying cost (capital tied up for years), storage under controlled humidity for moisture-sensitive parts, insurance, the write-off risk if the product ends earlier than planned or a mid-life redesign happens anyway, and the scrap risk from date-code policies. A common rule of thumb puts annual carrying cost at a meaningful percentage of inventory value; over a five-year horizon this materially changes the comparison against redesign.\u003C\u002Fp>\n\u003Cp>Structure the buy to manage its own risks: split storage across locations if quantity justifies it, keep full lot and date-code documentation with the stock, and book a revisit every six to twelve months to compare actual consumption against the plan while some corrective options still exist.\u003C\u002Fp>\n\u003Ch2>Option 2: Bridge Buy\u003C\u002Fh2>\n\u003Cp>A bridge buy purchases enough stock to cover production only until a qualified alternate takes over. The sizing anchor is the alternate qualification timeline, not the product life: if qualification realistically takes nine months, the bridge is nine months of demand plus a slip allowance, not three years of it.\u003C\u002Fp>\n\u003Cp>This is usually the most capital-efficient option, but it carries schedule risk: the plan fails if qualification slips past the stock. Protect it three ways. First, add explicit buffer — a bridge sized at qualification-time-plus-fifty-percent is common where the alternate is not yet proven. Second, define a checkpoint date on which qualification progress is reviewed while the LTB window may still be open, preserving the ability to convert to a larger buy. Third, have a fallback source identified for the original part (authorized residual stock, authenticated open market) in case both the schedule and the window are missed.\u003C\u002Fp>\n\u003Cp>A bridge buy is only as credible as the qualification plan behind it. Footprint, electrical, behavioral, thermal, and compliance verification of the candidate part is its own workflow, covered in our guide to \u003Ca href=\\\"\u002Fresource\u002Ftechnical-knowledge\u002Fqualify-pin-compatible-alternate-no-respin\u002F\\\">qualifying a pin-compatible alternate without a board respin\u003C\u002Fa>.\u003C\u002Fp>\n\u003Ch2>Option 3: Redesign\u003C\u002Fh2>\n\u003Cp>Redesign replaces the at-risk part with an active one, accepting layout, firmware, and requalification cost in exchange for eliminating the obsolescence exposure entirely.
