RC6432F7681CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F7681CS is a 7.68 kOhms ±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 1084 pieces available in new original inventory. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component, enabling direct replacement in applications where the original part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F7681CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (7.68 kOhms), tolerance (±1%), and power rating (1W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) must match or exceed the original specification.

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

Composition & Construction: Thick film construction is required to maintain electrical performance characteristics and thermal behavior equivalent to the original part.

Compliance & Certification: RoHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) are mandatory for direct substitution in regulated applications.

The CRCW25127K68FKEG manufactured by Vishay Dale meets all substitution criteria and is classified as an equivalent substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F7681CS and CRCW25127K68FKEG are active production components with ROHS3 compliance and unlimited moisture sensitivity rating. The electrical and thermal specifications are identical, ensuring functional equivalence in circuit applications.

The CRCW25127K68FKEG carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. This qualification does not restrict use in non-automotive applications and represents an enhanced specification level.

Dimensional variations between the two parts are minimal: the width difference is 0.002" (0.05mm) and the height difference is 0.002" (0.04mm). These variations remain within standard PCB design tolerances for 2512 package footprints and do not affect assembly or electrical performance.

Selection between these parts should be based on inventory availability, packaging format requirements (the Samsung part is specified with "-" packaging while the Vishay part is supplied in Tape & Reel format), and any specific procurement or qualification requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can the CRCW25127K68FKEG directly replace the RC6432F7681CS on a PCB?

A: Yes. Both parts share identical electrical specifications (7.68 kOhms ±1%, 1W, ±100ppm/°C, -55°C ~ 155°C), identical package designation (2512 / 6432 Metric), and identical termination count (2). Dimensional variations (0.002" width, 0.002" height) are within standard PCB design tolerances for this package class.

Q: What does AEC-Q200 qualification on the Vishay part mean for non-automotive applications?

A: AEC-Q200 is an automotive reliability standard that establishes enhanced testing and quality requirements. Parts meeting this standard are suitable for any application, including non-automotive use. The qualification represents a higher assurance level and does not restrict component application scope.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RC6432F7681CS and CRCW25127K68FKEG are ROHS3 compliant, meeting current environmental and hazardous substance restrictions for electronic components.

Q: What is the significance of Moisture Sensitivity Level 1 (Unlimited)?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. These parts do not require special moisture-controlled storage, handling, or reflow procedures and can be stored and processed under standard industrial conditions.

Q: Do the packaging format differences affect substitution?

A: Packaging format (Tape & Reel versus other formats) affects supply chain logistics and automated assembly processes but does not affect the electrical or mechanical compatibility of the component itself. Format selection depends on manufacturing process requirements and inventory management practices.

Q: Are the temperature coefficient specifications identical?

A: Yes. Both parts specify ±100ppm/°C temperature coefficient and operate across the identical temperature range of -55°C to 155°C, ensuring equivalent thermal performance in circuit applications.
