Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F4422CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (44.2 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 format must be 2512 (6432 Metric) to ensure PCB footprint compatibility. Physical dimensions and termination count (2 terminations) must match or remain within acceptable assembly tolerances.

Composition & Construction: Thick film construction is the specified technology. Moisture resistance capability must be maintained.

Compliance & Certification: ROHS3 compliance and MSL 1 rating are mandatory for substitute acceptance. Product status must be Active.

The CRCW251244K2FKEG from Vishay Dale meets all substitution criteria while adding automotive AEC-Q200 qualification, making it functionally and mechanically interchangeable with the RC6432F4422CS.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F4422CS and CRCW251244K2FKEG are Active products with identical electrical and mechanical specifications. Selection between these components should be based on application requirements and supply chain considerations.

The RC6432F4422CS from Samsung Electro-Mechanics is suitable for general-purpose applications requiring moisture-resistant thick film resistors with standard industrial compliance.

The CRCW251244K2FKEG from Vishay Dale provides the same core functionality with additional automotive AEC-Q200 qualification. This certification is relevant only for applications requiring automotive-grade component reliability. For non-automotive applications, this additional qualification does not alter functional performance.

Both components maintain ROHS3 compliance, unlimited moisture sensitivity rating, and identical thermal operating parameters. Packaging format (Tape & Reel for CRCW251244K2FKEG versus standard packaging for RC6432F4422CS) may influence procurement and assembly processes but does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can CRCW251244K2FKEG directly replace RC6432F4422CS in existing designs?

A: Yes. Both components share identical resistance (44.2 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 significance of AEC-Q200 qualification on the CRCW251244K2FKEG?

A: AEC-Q200 is an automotive industry standard for discrete semiconductors and passive components. This certification indicates the component meets automotive reliability and quality requirements. For non-automotive applications, this qualification provides no functional advantage over the RC6432F4422CS.

Q: Are there dimensional differences between these parts?

A: Both components use the 2512 (6432 Metric) package. The RC6432F4422CS has a maximum seated height of 0.026" (0.66mm) with dimensions 0.248" L x 0.126" W. The CRCW251244K2FKEG has a maximum seated height of 0.028" (0.70mm) with dimensions 0.248" L x 0.124" W. These minor variations remain within standard PCB assembly tolerances and do not affect interchangeability.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both RC6432F4422CS and CRCW251244K2FKEG are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts carry this rating, eliminating moisture-related procurement or storage constraints.

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

A: Yes. Both components operate across the identical temperature range of -55°C to 155°C with matching temperature coefficient (±100ppm/°C), ensuring equivalent thermal performance in temperature-sensitive circuits.
