Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F3651CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (3.65 kOhms), tolerance (±1%), power rating (1W), and temperature coefficient (±100ppm/°C) must match exactly.

Mechanical Compatibility: Package format must be 2512 (6432 Metric) with two terminations to ensure PCB footprint compatibility and assembly process alignment.

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

Composition: Thick film construction ensures consistent performance characteristics across thermal cycling and environmental exposure.

The CRCW25123K65FKEG from Vishay Dale meets all substitution criteria while adding automotive-grade AEC-Q200 qualification, making it suitable for applications requiring enhanced reliability standards.

Engineering Selection Recommendations

Primary Selection (RC6432F3651CS): Select the Samsung Electro-Mechanics RC6432F3651CS for general-purpose applications where standard industrial compliance and moisture resistance are required. Active product status ensures continued availability and supply chain stability.

Substitute Selection (CRCW25123K65FKEG): Select the Vishay Dale CRCW25123K65FKEG when automotive-grade reliability is mandated or when enhanced qualification documentation is required for regulated applications. AEC-Q200 certification provides additional assurance for automotive and high-reliability environments. Both parts maintain identical electrical and thermal performance characteristics.

Compliance Alignment: Both parts satisfy ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across global markets. MSL 1 rating on both components eliminates moisture-related handling constraints during assembly and storage.

Frequently Asked Questions (FAQ)

Q: Can CRCW25123K65FKEG directly replace RC6432F3651CS in existing designs?

A: Yes. Both parts share identical resistance (3.65 kOhms), tolerance (±1%), power rating (1W), package format (2512), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). PCB footprints and electrical performance are equivalent.

Q: What is the difference between these two parts?

A: The primary difference is automotive qualification. CRCW25123K65FKEG carries AEC-Q200 certification, indicating enhanced reliability testing and qualification for automotive applications. RC6432F3651CS does not specify automotive qualification. Electrical and thermal specifications are identical.

Q: Are there packaging differences between these parts?

A: Both use the 2512 (6432 Metric) package with identical termination count (2). Dimensional specifications are nearly identical: RC6432F3651CS measures 0.248" L x 0.126" W (6.30mm x 3.20mm), while CRCW25123K65FKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm). Height differences (0.66mm vs 0.70mm) are within standard PCB assembly tolerances and do not affect compatibility.

Q: Do both parts meet environmental compliance requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) rating. No special handling or storage conditions are required for either component.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For automotive or high-reliability applications, CRCW25123K65FKEG is preferred due to AEC-Q200 qualification. For general industrial applications, either part is suitable based on availability and cost considerations.
