RC6432F4533CS Equivalent & Substitute Parts

Part Overview

The RC6432F4533CS is a 453 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package format. This thick film, moisture-resistant component operates across a temperature range of -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status with 980 pieces available in inventory.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design requirements permit the use of functionally equivalent components from different manufacturers that meet identical electrical and mechanical specifications.

The package dimensions are functionally equivalent within standard PCB assembly tolerances. Both parts carry ROHS3 compliance and MSL 1 ratings, ensuring compatibility in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

RC6432F4533CS (Samsung Electro-Mechanics) is the primary selection for new designs. This part maintains active production status and is recommended for all new circuit implementations. The component is currently in stock with 980 pieces available.

ERJ-1TNF4533U (Panasonic Electronic Components) is suitable for replacement applications and legacy design support. This part carries "Not For New Designs" status and should be used only when substituting existing assemblies or when the primary part is unavailable. The Panasonic part includes AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. Inventory availability is higher at 3060 pieces.

Both parts satisfy ROHS3 compliance and REACH requirements. Selection between these parts should be based on design phase (new versus legacy), supply chain availability, and application-specific requirements for automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF4533U be used as a direct replacement for RC6432F4533CS in existing designs?

A: Yes. Both parts share identical electrical specifications (453 kOhms, ±1%, 1W, ±100ppm/°C, -55°C to 155°C operating range) and are packaged in the 2512 (6432 Metric) format. Dimensional variations (0.248" vs 0.252" length, 0.026" vs 0.028" height) fall within standard PCB assembly tolerances and do not affect functional compatibility.

Q: Why is the Panasonic part marked "Not For New Designs"?

A: This designation indicates that while the part remains available and functional, Panasonic recommends using alternative current-generation components for new circuit designs. The part remains suitable for replacement and legacy applications.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 ratings. The Panasonic part includes AEC-Q200 automotive qualification, which the Samsung part does not specify. This additional qualification is relevant only for applications requiring automotive-grade component certification.

Q: What is the significance of the 2512 package designation?

A: The 2512 package (6432 Metric) is a standardized surface-mount resistor format measuring 6.30mm x 3.20mm (Samsung) or 6.40mm x 3.20mm (Panasonic). Both parts use this identical package family, ensuring PCB footprint compatibility.

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

A: Yes. Both parts operate across the identical temperature range of -55°C to 155°C with matching temperature coefficients of ±100ppm/°C, ensuring equivalent performance in thermal cycling and high-temperature environments.
