Parameter Comparison

Engineering Selection Recommendations

All three parts meet the core electrical and mechanical requirements for 30 kOhms ±1% 1W thick film resistor applications in the 2512 package format. Selection between these parts is determined by application requirements and supply chain considerations:

RC6432F303CS (Samsung Electro-Mechanics): Select when Samsung component qualification is required or when bulk packaging is preferred. Maintains Active product status with standard moisture-resistant thick film construction.

RC2512FK-0730KL (YAGEO): Select as a direct functional equivalent with identical electrical performance. Available in Tape & Reel packaging format. Maintains Active product status with standard moisture-resistant thick film construction.

RMCF2512FT30K0 (Stackpole Electronics Inc): Select when automotive-grade qualification is required. This part carries AEC-Q200 automotive qualification in addition to all standard electrical specifications. Available in Tape & Reel packaging format. Maintains Active product status.

All parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-0730KL be used as a direct replacement for RC6432F303CS?

A: Yes. Both parts share identical electrical specifications (30 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C operating range) and the same 2512 package format. The primary difference is packaging format (bulk versus Tape & Reel) and manufacturer series designation.

Q: What is the difference between RC2512FK-0730KL and RMCF2512FT30K0?

A: Both parts match all electrical specifications and package requirements. RMCF2512FT30K0 includes AEC-Q200 automotive qualification, making it suitable for automotive applications. RC2512FK-0730KL is a standard industrial-grade equivalent without automotive certification.

Q: Are the physical dimensions compatible across all three parts?

A: All three parts use the 2512 (6432 Metric) package format. Dimensional variations are minimal: RC6432F303CS and RMCF2512FT30K0 measure 0.248" L x 0.126" W (6.30mm x 3.20mm), while RC2512FK-0730KL measures 0.250" L x 0.122" W (6.35mm x 3.10mm). Height differences range from 0.026" to 0.028" (0.65mm to 0.70mm). These variations are within standard PCB design tolerances for 2512 package footprints.

Q: Which part should be selected for automotive applications?

A: RMCF2512FT30K0 is qualified to AEC-Q200 automotive standards and is the appropriate selection for automotive circuit applications.

Q: Are all parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) and REACH unaffected status.

Q: What packaging formats are available?

A: RC6432F303CS is supplied in bulk packaging. RC2512FK-0730KL and RMCF2512FT30K0 are supplied in Tape & Reel (TR) format for automated assembly processes.
