Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC6432F4752CS is determined by strict equivalence across the following critical parameters:

• Resistance Value: 47.5 kOhms (exact match required)
• Tolerance: ±1% (precision specification)
• Power Rating: 1W (thermal dissipation requirement)
• Package Format: 2512 (6432 Metric) (PCB footprint compatibility)
• Composition: Thick Film (electrical performance characteristics)
• Temperature Coefficient: ±100ppm/°C (frequency and stability performance)
• Operating Temperature Range: -55°C ~ 155°C (environmental specification)
• Termination Count: 2 (circuit connectivity)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected (legal and environmental requirements)

The identified substitute part CRCW251247K5FKEG from Vishay Dale meets all mandatory electrical and mechanical parameters. Packaging configuration differs (Tape & Reel versus standard packaging), and the substitute includes automotive AEC-Q200 qualification, which represents an enhancement rather than a limitation for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F4752CS and CRCW251247K5FKEG are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on application requirements and supply chain considerations:

RC6432F4752CS (Samsung Electro-Mechanics) is appropriate for applications requiring the original specified component or when standard packaging is preferred. Current inventory of 731 units supports immediate procurement.

CRCW251247K5FKEG (Vishay Dale) is appropriate for applications requiring automotive-grade reliability through AEC-Q200 qualification, or when Tape & Reel packaging is required for automated assembly processes. Higher inventory availability (5095 units) supports extended production runs. Dimensional variations (width 3.15mm versus 3.20mm, height 0.70mm versus 0.66mm) remain within standard PCB footprint tolerances for the 2512 package format.

Both components are electrically and mechanically interchangeable within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can CRCW251247K5FKEG replace RC6432F4752CS in existing designs?

A: Yes. Both components share identical electrical specifications (47.5 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C operating range) and are packaged in the 2512 (6432 Metric) format. Dimensional variations (0.124" versus 0.126" width, 0.028" versus 0.026" height) are within standard PCB footprint tolerances for this package class.

Q: What is the significance of AEC-Q200 qualification on the Vishay part?

A: AEC-Q200 is an automotive industry qualification standard. This certification indicates the component meets automotive reliability and quality requirements. For non-automotive applications, this represents an enhancement that does not restrict use in general-purpose circuits.

Q: Does packaging type affect electrical performance?

A: No. Tape & Reel (TR) packaging is a delivery and handling format used for automated assembly processes. It does not alter the electrical characteristics or performance of the component itself.

Q: Are there any compliance differences between these parts?

A: No. Both components are ROHS3 compliant and REACH unaffected. Regulatory status is identical.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture bake requirements. Both components carry this rating, meaning they can be stored and handled without special moisture control procedures.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both components operate across the identical temperature range of -55°C to 155°C with matching temperature coefficients of ±100ppm/°C.
