WSL2512R Overview

What changes between part numbers, and what to check before you lock the BOM — Passive Components.

WSL2512R is a Vishay order-code family — not a single orderable MPN. This page lists 41 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.

0.01 Ohm 1W 1% Metal Strip Resistor, 2512 SMD Other listed variants describe: 2W 1% 10mR Metal Strip Current Sense Resistor, 2512 SMD; Res Metal Strip 2512 0.01 Ohm 1% 1W ±75ppm/°C Molded SMD SMD T/R.

Suffix examples in this family: 0100FEA, 0100FEA18, 0100FEB, 0120FEA, 0120FEA18, 0130FEA18, 0140FEA18, 0150FEA. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.

Example MPNs: WSL2512R0100FEA, WSL2512R0100FEA18, WSL2512R0100FEB, WSL2512R0120FEA, WSL2512R0120FEA18, WSL2512R0130FEA18.

Ordering Code Differences

How suffixes on WSL2512R map to package, grade, and reel options.

WSL2512R uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.

Suffixes seen here: 0100FEA, 0100FEA18, 0100FEB, 0120FEA, 0120FEA18, 0130FEA18, 0140FEA18, 0150FEA, 0150FEA18, 0160FEA18 (+31 more).

Full MPN examples: WSL2512R0100FEA, WSL2512R0100FEA18, WSL2512R0100FEB, WSL2512R0120FEA, WSL2512R0120FEA18.

Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.

How to Choose the Right WSL2512R Passive Components

📦

Match the footprint first

Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For WSL2512R, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.

🌡️

Temp grade letter matters

Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.

🔢

Copy the full MPN

Do not BOM only "WSL2512R" — include the full suffix (e.g. 0100FEA, 0100FEA18, 0100FEB). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the WSL2512R product family.

Is WSL2512R a single part I can order, or a family prefix?

WSL2512R is a base / family code from Vishay. You order a full MPN such as WSL2512R0100FEA, WSL2512R0100FEA18, WSL2512R0100FEB. The variant table lists 41 orderable lines with different suffixes.

What do the suffix letters on WSL2512R part numbers mean?

Listed suffix fragments include: 0100FEA, 0100FEA18, 0100FEB, 0120FEA, 0120FEA18, 0130FEA18. Typically they encode package (see Package column), temperature grade, and tape/reel option. Always decode on the Vishay datasheet ordering guide — do not guess from pattern alone.

What is the lifecycle status of WSL2512R variants?

Lifecycle values in our listing: Active. Status is per MPN suffix — one variant can be Active while another is NRND. Check PCN for your exact suffix before multi-year commitments.

What should I send for an RFQ on WSL2512R?

Full manufacturer MPN (not just WSL2512R), quantity, needed date code, reel vs tube, and any compliance docs (CoC, RoHS, conflict minerals). If you only know the base prefix, include a photo of the existing label or reel.

Where is the WSL2512R datasheet?

Use the datasheet link in the page header. Cross-check electrical curves (SOA, saturation voltage, etc.) against your operating point — the table summarizes order codes, not every graph in the PDF.
