Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1051CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (1.05 kOhms), tolerance (±1%), and power rating (1W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (2512 / 6432 Metric), physical dimensions (0.248" L x 0.126" W / 6.30mm x 3.20mm), and termination count (2) ensure PCB footprint compatibility and assembly process alignment.

Compliance & Certification: ROHS3 compliance and MSL 1 rating confirm environmental and handling requirements. Composition (Thick Film) defines manufacturing process and performance characteristics.

The identified substitute CRCW25121K05FKEG from Vishay Dale meets all electrical and mechanical parameters while adding automotive-grade AEC-Q200 qualification, representing an enhanced alternative within the same functional class.

Engineering Selection Recommendations

RC6432F1051CS (Samsung Electro-Mechanics): Select this component for standard industrial applications requiring moisture-resistant thick film construction. Active product status ensures ongoing availability and supply chain stability. ROHS3 compliance and MSL 1 rating support standard manufacturing and storage protocols.

CRCW25121K05FKEG (Vishay Dale): Select this substitute for applications requiring automotive-grade reliability. AEC-Q200 qualification provides enhanced qualification testing and performance validation suitable for automotive and mission-critical environments. Identical electrical and mechanical parameters ensure direct PCB compatibility. Both components maintain ROHS3 compliance and unlimited moisture sensitivity level.

Physical dimension variance (width 0.126" vs 0.124", height 0.026" vs 0.028") falls within standard PCB design tolerances and does not affect functional substitution.

Frequently Asked Questions (FAQ)

Q: Can CRCW25121K05FKEG replace RC6432F1051CS in existing designs?

A: Yes. Both components share identical resistance (1.05 kOhms), tolerance (±1%), power rating (1W), package designation (2512), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Physical dimensions are within standard PCB tolerance ranges. Direct substitution is electrically and mechanically compatible.

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

A: AEC-Q200 is an automotive industry standard qualification that certifies enhanced reliability testing and performance validation. This qualification does not alter electrical or mechanical specifications but indicates suitability for automotive and high-reliability applications. Non-automotive applications are unaffected by this certification.

Q: Are there packaging differences between these parts?

A: RC6432F1051CS is supplied in standard packaging format. CRCW25121K05FKEG is supplied in Tape & Reel (TR) format. Both use identical 2512 (6432 Metric) package designation. Tape & Reel packaging is standard for automated assembly processes and does not affect component performance or compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity level). Compliance certifications are equivalent across both parts.

Q: What is the tolerance on physical dimensions?

A: Width variance is 0.002" (0.15mm) and height variance is 0.002" (0.04mm). These differences are within standard PCB design and assembly tolerances and do not affect footprint compatibility or functional performance.
