RC6432F43R2CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F43R2CS is a 43.2 Ohms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film resistor features moisture resistance and operates across the temperature range of -55°C to 155°C. The part is currently in active production status with 983 pieces available in inventory.

Substitute parts are necessary when the primary manufacturer experiences supply constraints, when design requirements mandate specific certifications such as AEC-Q200 automotive qualification, or when alternative packaging formats are required for manufacturing processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F43R2CS is determined by strict equivalence across the following parameters:

Mandatory Matching Parameters:

• Resistance: 43.2 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 1W (minimum requirement)
• Package: 2512 (6432 Metric) (physical footprint compatibility)
• Composition: Thick Film (electrical performance characteristics)
• Temperature Coefficient: ±100ppm/°C (stability specification)
• Operating Temperature Range: -55°C ~ 155°C (environmental specification)

Compliance Parameters:

• RoHS3 Compliant status (regulatory requirement)
• Moisture Sensitivity Level 1 (handling compatibility)

All three substitute parts listed meet these mandatory criteria. Dimensional variations within the 2512 package specification and differences in packaging format (Tape & Reel versus bulk) do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC6432F43R2CS - Samsung Electro-Mechanics): Use the original Samsung part when available. It meets all electrical and environmental specifications and maintains active production status.

First Alternative (RMCF2512FT43R2 - Stackpole Electronics Inc): Select this substitute when Samsung supply is unavailable. Stackpole maintains active product status, provides AEC-Q200 automotive qualification, and offers higher inventory availability (4244 pieces). Dimensional specifications are identical to the primary part.

Second Alternative (CRCW251243R2FKEG - Vishay Dale): This substitute is suitable when Stackpole supply is constrained. Vishay Dale maintains active status with AEC-Q200 qualification and the highest inventory level (4605 pieces). Dimensional variation is minimal (width 3.15mm versus 3.20mm standard) and remains within 2512 package tolerance.

Not Recommended for New Designs (ERJ-1TNF43R2U - Panasonic): Although this part meets all electrical specifications and offers the highest inventory (12232 pieces), Panasonic has designated this part as "Not For New Designs." Use only for legacy system maintenance or repair applications where the original part specification is mandatory.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RC6432F43R2CS with any of the listed alternatives without circuit redesign?

A: Yes. All listed substitutes match the critical electrical parameters: 43.2 Ohms resistance, ±1% tolerance, 1W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Physical footprint compatibility is maintained across all alternatives within the 2512 package specification.

Q: What is the difference between the Samsung part and the Vishay Dale CRCW251243R2FKEG?

A: Both parts are electrically equivalent. The primary differences are: Vishay Dale includes AEC-Q200 automotive qualification (not specified for Samsung), packaging is Tape & Reel format (Samsung format not specified), and width dimension is 3.15mm versus 3.20mm standard. These differences do not affect functional substitution.

Q: Why is the Panasonic ERJ-1TNF43R2U marked "Not For New Designs"?

A: Panasonic has discontinued this product line for new applications. While the part remains electrically equivalent and is available in high quantities, it should only be used for maintenance of existing systems or legacy applications where original part specifications are required.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed parts, including the primary RC6432F43R2CS and all three substitutes, are RoHS3 compliant and REACH unaffected.

Q: Does packaging format (Tape & Reel versus bulk) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly process compatibility. Electrical and thermal performance remain identical regardless of packaging format.

Q: Can I use these substitutes in automotive applications?

A: The Vishay Dale CRCW251243R2FKEG, Panasonic ERJ-1TNF43R2U, and Stackpole RMCF2512FT43R2 all carry AEC-Q200 automotive qualification. The Samsung RC6432F43R2CS does not specify automotive qualification. Verify application requirements before selection.
