Operating temperature range: -55°C to 155°C minimum

Mechanical Parameters (Non-Negotiable):

Package: 2512 (6432 Metric)
Composition: Thick Film
Number of terminations: 2
Moisture resistance: Required

Power Rating (Flexible - Upgrade Acceptable):

Minimum 1W; higher ratings (1.5W, 2W) are acceptable substitutes

Q: Which substitute offers the best inventory availability?

A: RC2512FK-071K5L (YAGEO) has the highest inventory with 685,843 pieces in stock, compared to 700 pieces for the original RC6432F152CS.

Q: Can I use CRCW25121K50FKTG in a new design?

A: CRCW25121K50FKTG is RoHS non-compliant and REACH affected. It should not be used in new designs requiring regulatory compliance. Select CRCW25121K50FKEG or CRCW25121K50FKEGHP instead, which are ROHS3 compliant.

Q: What is the difference between standard and automotive-qualified versions?

A: Automotive-qualified parts (AC2512FK-071K5L, RMCF2512FT1K50, CRCW25121K50FKEG, CRCW25121K50FKEGHP) carry AEC-Q200 certification, indicating compliance with automotive reliability and quality standards.
