Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Identical Specifications):

CRCW251230R1FKEG and RMCF2512FT30R1 are direct electrical and mechanical equivalents to RC6432F30R1CS. Both parts maintain identical resistance, tolerance, power rating, package dimensions, and temperature characteristics. Both substitute parts carry Automotive AEC-Q200 qualification, which exceeds the original component's specified compliance level. These parts are suitable for direct replacement in applications where the original RC6432F30R1CS is specified.

Enhanced Performance Alternative:

CRCW251230R1FKEGHP provides increased power dissipation capability at 1.5W with pulse withstanding features while maintaining all other electrical and mechanical parameters. This part is applicable in applications requiring higher transient power handling or where design margin enhancement is beneficial. The 2512 package dimensions remain compatible with the original design.

All substitute parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and the full operating temperature range of -55°C ~ 155°C specified for the original component.

Frequently Asked Questions (FAQ)

Q: Can CRCW251230R1FKEG replace RC6432F30R1CS in existing designs?

A: Yes. CRCW251230R1FKEG is electrically and mechanically equivalent with identical resistance (30.1 Ohms ±1%), power rating (1W), package (2512), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Both components are ROHS3 compliant with MSL rating of 1.

Q: What is the difference between CRCW251230R1FKEG and CRCW251230R1FKEGHP?

A: The primary difference is power rating. CRCW251230R1FKEG is rated at 1W, while CRCW251230R1FKEGHP is rated at 1.5W with pulse withstanding capability. All other electrical and mechanical parameters are identical. CRCW251230R1FKEGHP is suitable for applications requiring higher power dissipation or transient pulse handling.

Q: Are all substitute parts compatible with the 2512 package footprint?

A: Yes. All substitute parts use the 2512 (6432 Metric) package with identical termination count (2) and compatible physical dimensions. Dimensional variations are within standard manufacturing tolerances for this package class.

Q: Do the substitute parts meet automotive standards?

A: CRCW251230R1FKEG, CRCW251230R1FKEGHP, and RMCF2512FT30R1 all carry Automotive AEC-Q200 qualification. The original RC6432F30R1CS does not specify automotive qualification. Automotive-qualified substitutes are suitable for both general industrial and automotive applications.

Q: What is the temperature coefficient significance for these parts?

A: All parts, including the original and substitutes, have a temperature coefficient of ±100ppm/°C. This specification defines the resistance change per degree Celsius across the operating temperature range of -55°C ~ 155°C. Identical temperature coefficients ensure equivalent thermal performance characteristics.

Q: Are moisture sensitivity considerations the same across all parts?

A: Yes. The original RC6432F30R1CS and all substitute parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly.
