MMZ1005S Overview

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

MMZ1005S is a TDK order-code family — not a single orderable MPN. This page lists 13 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.

FERRITE BEAD 1K OHM 0402 1LN Other listed variants describe: FERRITE BEAD 120 OHM 0402 1LN; FERRITE BEAD 1.8K OHM 0402 1LN.

Suffix examples in this family: 102CT000, 102CTD25, 102ET000, 102HT000, 121CT000, 121CTD25, 121HT000, 182ETD25. 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: MMZ1005S102CT000, MMZ1005S102CTD25, MMZ1005S102ET000, MMZ1005S102HT000, MMZ1005S121CT000, MMZ1005S121CTD25.

Key Features

Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
13 distinct suffix patternsExamples: 102CT000, 102CTD25, 102ET000, 102HT000, 121CT000 (+8 more). Decode suffix meaning in the ordering notes under the variant table.

Target Applications

Microcontrollers — design-in and field replacement
BOM scrub where only the base prefix is known but suffix is TBD

Ordering Code Differences

How suffixes on MMZ1005S map to package, grade, and reel options.

MMZ1005S 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: 102CT000, 102CTD25, 102ET000, 102HT000, 121CT000, 121CTD25, 121HT000, 182ETD25, 241CT000, 601CT000 (+3 more).

Full MPN examples: MMZ1005S102CT000, MMZ1005S102CTD25, MMZ1005S102ET000, MMZ1005S102HT000, MMZ1005S121CT000.

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 MMZ1005S Microcontrollers

📦

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 MMZ1005S, 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 "MMZ1005S" — include the full suffix (e.g. 102CT000, 102CTD25, 102ET000). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the MMZ1005S product family.

Is MMZ1005S a single part I can order, or a family prefix?

MMZ1005S is a base / family code from TDK. You order a full MPN such as MMZ1005S102CT000, MMZ1005S102CTD25, MMZ1005S102ET000. The variant table lists 13 orderable lines with different suffixes.

What do the suffix letters on MMZ1005S part numbers mean?

Listed suffix fragments include: 102CT000, 102CTD25, 102ET000, 102HT000, 121CT000, 121CTD25. Typically they encode package (see Package column), temperature grade, and tape/reel option. Always decode on the TDK datasheet ordering guide — do not guess from pattern alone.

What is the lifecycle status of MMZ1005S 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 MMZ1005S?

Full manufacturer MPN (not just MMZ1005S), 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 MMZ1005S 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.
