Substitute Part Grouping Explanation

Substitute parts for the RC6432F1402CS are qualified based on the following criteria:

Electrical Parameters: Resistance value (14 kOhms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C) must be identical.

Mechanical Parameters: Package designation (2512 / 6432 Metric) and number of terminations (2) must match to ensure PCB footprint compatibility and assembly process compatibility.

Compliance & Certification: RoHS3 compliance and MSL rating (1 - Unlimited) are required for environmental and handling consistency.

Composition: Thick film construction is maintained across all substitutes to preserve thermal and frequency response characteristics.

The identified substitute parts meet all these criteria and are therefore electrically and mechanically interchangeable with the RC6432F1402CS.

Engineering Selection Recommendations

All three components—RC6432F1402CS (Samsung Electro-Mechanics), CRCW251214K0FKEG (Vishay Dale), and RMCF2512FT14K0 (Stackpole Electronics Inc)—are Active product status and meet ROHS3 compliance requirements. The electrical specifications are identical across all three parts, ensuring functional equivalence in circuit applications.

The CRCW251214K0FKEG and RMCF2512FT14K0 both carry AEC-Q200 automotive qualification ratings, which provides additional reliability assurance for applications requiring automotive-grade components. The RC6432F1402CS features moisture-resistant construction without automotive qualification.

Dimensional variations exist in seated height (RC6432F1402CS: 0.026" maximum versus 0.028" maximum for both substitute parts) and width (CRCW251214K0FKEG: 3.15mm versus 3.20mm for the other two). These variations remain within standard PCB design tolerances for 2512 package footprints and do not affect electrical performance or assembly compatibility.

Selection between these parts should be based on availability, supply chain requirements, and application-specific compliance needs. All three parts are suitable for direct substitution in circuits designed for the RC6432F1402CS.

Frequently Asked Questions (FAQ)

Q: Can CRCW251214K0FKEG or RMCF2512FT14K0 be used as direct replacements for RC6432F1402CS?

A: Yes. All three components share identical electrical specifications (14 kOhms, ±1%, 1W, ±100ppm/°C, -55°C to 155°C operating range) and are packaged in the 2512 (6432 Metric) form factor. They are electrically and mechanically interchangeable.

Q: What is the significance of AEC-Q200 qualification on the substitute parts?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive operating conditions. The CRCW251214K0FKEG and RMCF2512FT14K0 carry this certification, while the RC6432F1402CS does not. This distinction is relevant only if the application requires automotive-grade components.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The RC6432F1402CS and RMCF2512FT14K0 have identical length and width (6.30mm x 3.20mm), while the CRCW251214K0FKEG width is 3.15mm. Seated height differs slightly: RC6432F1402CS is 0.66mm maximum, while both substitutes are 0.70mm maximum. These variations are within standard 2512 package tolerances and do not affect PCB footprint compatibility.

Q: Do all three parts have the same moisture sensitivity rating?

A: Yes. All three components have MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What compliance certifications apply to all three parts?

A: All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Which part should be selected for new designs?

A: Selection depends on supply chain availability and application requirements. For general-purpose applications, any of the three parts is suitable. For automotive applications, the CRCW251214K0FKEG or RMCF2512FT14K0 are preferred due to AEC-Q200 qualification.
