Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F3570CS are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Electrical Parameters:

• Resistance value: 357 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package / Case: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of Terminations: 2 (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The CRCW2512357RFKEGHP from Vishay Dale meets all mandatory substitution criteria. This part maintains identical electrical specifications and package format while offering enhanced power rating (1.5W versus 1W) and automotive-grade qualification (AEC-Q200), making it suitable for direct substitution in applications where the main part is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F3570CS and CRCW2512357RFKEGHP are Active product status components with full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and deployment.

The RC6432F3570CS is the primary specification component and should be used when Samsung Electro-Mechanics sourcing is required or when the 1W power rating is the design specification.

The CRCW2512357RFKEGHP from Vishay Dale serves as a direct electrical and mechanical substitute with the following distinctions:

• Enhanced power rating of 1.5W provides additional thermal margin in applications operating at or near the 1W specification limit
• AEC-Q200 automotive qualification indicates suitability for automotive and high-reliability applications
• Pulse withstanding capability provides enhanced transient performance
• Dimensional variance (height 0.028" versus 0.026") remains within standard PCB assembly tolerances for 2512 package components

Selection between these parts should be based on supply chain requirements, application-specific power dissipation analysis, and sourcing preferences rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512357RFKEGHP be used as a direct replacement for RC6432F3570CS?

A: Yes. Both components share identical resistance value (357 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), package format (2512/6432 Metric), and compliance status (ROHS3, REACH unaffected). The substitute part maintains full electrical and mechanical compatibility.

Q: What is the significance of the 1.5W power rating on the substitute part versus the 1W rating on the main part?

A: The 1.5W rating on CRCW2512357RFKEGHP indicates higher power dissipation capability. In applications where the RC6432F3570CS is specified at 1W, the substitute part can accommodate the same or greater power dissipation without thermal stress. This represents a performance enhancement rather than a limitation.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The RC6432F3570CS measures 0.248" L x 0.126" W with 0.026" maximum seated height. The CRCW2512357RFKEGHP measures 0.248" L x 0.124" W with 0.028" maximum seated height. Both conform to 2512 package specifications and are compatible with standard PCB assembly processes.

Q: What does AEC-Q200 qualification mean for the substitute part?

A: AEC-Q200 is an automotive electronics qualification standard. The CRCW2512357RFKEGHP meets this standard, indicating suitability for automotive applications and high-reliability environments. This qualification is not a requirement for general industrial applications but indicates enhanced quality assurance and testing protocols.

Q: Are both parts available in the same packaging format?

A: The RC6432F3570CS is supplied in standard packaging. The CRCW2512357RFKEGHP is supplied in Tape & Reel (TR) format. Both are compatible with automated assembly equipment. Packaging format selection depends on production volume and assembly process requirements.

Q: Do these parts have identical moisture sensitivity characteristics?

A: Yes. Both components are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions and no special handling or storage requirements beyond standard component storage practices.
