Engineering Selection Recommendations
For new designs and active production, select from parts with Active product status and ROHS3 compliance:
- CR1206-FX-5621ELF (Bourns Inc.) — Active status, moisture resistant features
- CRCW12065K62FKEA (Vishay Dale) — Active status, automotive AEC-Q200 rated
- RC1206FR-075K62L (YAGEO) — Active status, moisture resistant features
CRCW12065K62FKEAHP (Vishay Dale) provides higher power rating (0.75W) with pulse withstanding capability and AEC-Q200 qualification for applications requiring enhanced thermal performance.
CRCW12065K62FKTA (Vishay Dale) is not recommended for new designs due to RoHS non-compliance and REACH affected status.
ERJ-8ENF5621V (Panasonic Electronic Components) carries "Not For New Designs" status and should be used only for legacy system maintenance or repair applications.
Frequently Asked Questions (FAQ)
Q: Can CRCW12065K62FKEAHP (0.75W) replace RMCS1206FT5K62 (0.25W)?
A: Yes. The substitute has a higher power rating, which is acceptable for direct replacement. The 0.75W rating provides additional thermal margin without affecting circuit function at the original 0.25W operating point.
Q: Are all substitutes mechanically compatible with the 1206 package footprint?
A: All listed substitutes use the 1206 (3216 Metric) package. Minor dimensional variations exist within tolerance (height range 0.024" to 0.030"), but all are compatible with standard 1206 PCB layouts.
Q: Why is CRCW12065K62FKTA not recommended?
A: This part is RoHS non-compliant and REACH affected, making it unsuitable for applications requiring regulatory compliance. Use only if legacy system constraints mandate this specific part number.
Q: What is the difference between moisture resistant and anti-sulfur features?
A: Both features protect against environmental degradation. Anti-sulfur (RMCS1206FT5K62) and moisture resistant (CR1206-FX-5621ELF, RC1206FR-075K62L) formulations address different environmental stressors. Selection depends on application environment.
Q: Can ERJ-8ENF5621V be used in new designs?
A: No. This part carries "Not For New Designs" status. It is available for legacy system support only. Use CR1206-FX-5621ELF, CRCW12065K62FKEA, or RC1206FR-075K62L for new designs.
Q: What does AEC-Q200 qualification mean?
A: AEC-Q200 is an automotive qualification standard. CRCW12065K62FKEA and CRCW12065K62FKEAHP meet this standard, making them suitable for automotive and high-reliability applications.
