Yageo KEMET YC122
YC122 variants from Yageo KEMET
YC122 Overview
What changes between part numbers, and what to check before you lock the BOM — Passive Components.
YC122 is a Yageo order-code family — not a single orderable MPN. This page lists 12 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.
RES ARRAY 2 RES 49.9 OHM 0404 Other listed variants describe: RES ARRAY 2 RES 68 OHM 0404; Res Thick Film Array 0 Ohm ISOL Epoxy 4-Pin 0404(2 X 0402) Convex SMD Automotive T/R.
Suffix examples in this family: FR-0749R9L, FR-0768RL, JR-070RL, JR-07100RL, JR-0710KL, JR-071KL, JR-0722RL, JR-072KL. 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: YC122-FR-0749R9L, YC122-FR-0768RL, YC122-JR-070RL, YC122-JR-07100RL, YC122-JR-0710KL, YC122-JR-071KL.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 12 distinct suffix patternsExamples: FR-0749R9L, FR-0768RL, JR-070RL, JR-07100RL, JR-0710KL (+7 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Passive Components — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained

Ordering Code Differences
How suffixes on YC122 map to package, grade, and reel options.
YC122 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: FR-0749R9L, FR-0768RL, JR-070RL, JR-07100RL, JR-0710KL, JR-071KL, JR-0722RL, JR-072KL, JR-073RL, JR-0747RL (+2 more).
Full MPN examples: YC122-FR-0749R9L, YC122-FR-0768RL, YC122-JR-070RL, YC122-JR-07100RL, YC122-JR-0710KL.
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 YC122 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 YC122, 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 "YC122" — include the full suffix (e.g. FR-0749R9L, FR-0768RL, JR-070RL). RFQ with reel/tube preference and required date code.
