Frequently Asked Questions (FAQ)

Q: Can CRCW25128K66FKEG replace ERJ-S1TF8661U in automotive applications? A: Yes. Both components share identical electrical specifications (8.66 kOhms ±1%, 1W), operate across the same temperature range (-55°C ~ 155°C), carry AEC-Q200 certification, and are packaged in 2512 (6432 Metric) format. Mechanical dimensions are within acceptable tolerances for PCB assembly.

Q: What are the dimensional differences between substitute parts? A: Length varies slightly: ERJ-S1TF8661U measures 0.252" L × 0.126" W (6.40mm × 3.20mm), CRCW25128K66FKEG measures 0.248" L × 0.124" W (6.30mm × 3.15mm), and RMCF2512FT8K66 measures 0.248" L × 0.126" W (6.30mm × 3.20mm). All maintain identical height of 0.028" (0.70mm) and are compatible with standard 2512 footprints.

Q: Are all substitute parts RoHS compliant? A: Yes. All three components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting environmental and regulatory requirements for automotive electronics.

Q: Can these parts be used interchangeably in production? A: Yes. All parts are rated for Tape & Reel packaging and are suitable for automated pick-and-place assembly. Electrical performance and thermal characteristics are equivalent across all three manufacturers.
