RC6432F1541CS Equivalent & Substitute Parts

Part Overview

The RC6432F1541CS is a 1.54 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 the temperature range of -55°C to 155°C and maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). The part is currently in active production status with 787 units available in inventory. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component's functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1541CS is determined by strict alignment across the following critical parameters:

Electrical Parameters: Resistance value (1.54 kOhms), tolerance (±1%), power rating (1W), and temperature coefficient (±100ppm/°C) must match exactly.

Mechanical Parameters: Package designation (2512 / 6432 Metric) and termination count (2) must be identical to ensure PCB footprint compatibility and assembly process compatibility.

Environmental & Compliance Parameters: Operating temperature range (-55°C ~ 155°C), RoHS3 compliance status, and MSL rating (1 - Unlimited) must be maintained or exceeded.

Composition: Thick film construction is required to preserve electrical performance characteristics.

The CRCW25121K54FKEG from Vishay Dale qualifies as a direct substitute based on complete alignment across all specified parameters, with the addition of AEC-Q200 automotive qualification and Tape & Reel packaging format.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F1541CS and CRCW25121K54FKEG are active production components with ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts should be based on the following factors:

RC6432F1541CS (Samsung Electro-Mechanics): Select this part when moisture resistance is the primary environmental concern and standard industrial applications do not require automotive qualification. Current inventory of 787 units supports immediate availability.

CRCW25121K54FKEG (Vishay Dale): Select this part when AEC-Q200 automotive qualification is required or when higher inventory levels (4859 units) are needed. This part is supplied in Tape & Reel packaging format, which is standard for automated assembly processes. The automotive qualification provides additional reliability assurance for demanding applications.

Both parts maintain identical electrical performance and mechanical compatibility. The choice between them depends on application requirements (automotive vs. industrial) and packaging format preference (bulk vs. Tape & Reel).

Frequently Asked Questions (FAQ)

Q: Can CRCW25121K54FKEG be used as a direct replacement for RC6432F1541CS in existing designs?

A: Yes. Both parts share identical electrical specifications (1.54 kOhms ±1%, 1W), mechanical dimensions (2512 package), and environmental ratings (-55°C ~ 155°C operating range). PCB footprints and assembly processes are compatible. The CRCW25121K54FKEG includes additional AEC-Q200 automotive qualification, which does not restrict its use in non-automotive applications.

Q: What is the difference between the packaging formats?

A: The RC6432F1541CS is supplied in standard packaging format, while the CRCW25121K54FKEG is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly equipment and is the industry standard for high-volume production. Both formats contain identical components; the difference is in delivery and handling method.

Q: Are there any thermal performance differences between these parts?

A: No. Both parts have identical temperature coefficients (±100ppm/°C) and operating temperature ranges (-55°C ~ 155°C). Thermal performance is equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry MSL 1 (Unlimited) moisture sensitivity rating. The CRCW25121K54FKEG includes additional AEC-Q200 automotive qualification.

Q: Which part should be selected for new designs?

A: For new designs, either part is acceptable based on application requirements. If automotive qualification is needed or anticipated, select CRCW25121K54FKEG. For standard industrial applications without automotive requirements, either part is suitable. Consider inventory availability and packaging format requirements for your manufacturing process.
