Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F10R2CS is determined by strict alignment with the following core parameters:

Mandatory Matching Parameters:

• Resistance Value: 10.2 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 2512 (6432 Metric) (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Composition: Thick Film (exact match required)
• Number of Terminations: 2 (exact match required)

Allowable Variation Parameters:

• Power Rating: Substitute parts may exceed the 1W rating of the main part, provided all other electrical and mechanical parameters remain identical. Higher power ratings provide additional thermal margin without affecting circuit performance.
• Physical Dimensions: Minor variations within the 2512 package specification are acceptable (height and width tolerances within supplier specifications).
• Certifications and Features: Substitute parts may include additional certifications (such as AEC-Q200) or enhanced features (such as pulse withstanding capability) without compromising substitution validity.

The CRCW251210R2FKEGHP from Vishay Dale qualifies as a direct substitute based on this criteria.

Parameter Comparison

Engineering Selection Recommendations

The CRCW251210R2FKEGHP qualifies as a direct substitute for the RC6432F10R2CS based on electrical and mechanical parameter equivalence. Selection between these parts should be based on the following criteria:

Primary Selection Factors:

1. Inventory Availability: The CRCW251210R2FKEGHP maintains higher stock levels (3144 units) compared to the RC6432F10R2CS (792 units), supporting supply chain continuity.

2. Power Rating Enhancement: The substitute part provides 1.5W power rating versus the 1W rating of the main part. This increased thermal capacity is compatible with all applications designed for the 1W specification and provides additional margin in power-dissipation-sensitive circuits.

3. Automotive Certification: The CRCW251210R2FKEGHP carries AEC-Q200 automotive qualification and pulse withstanding capability. Applications requiring automotive-grade components benefit from these certifications. Applications without automotive requirements are unaffected by this additional qualification.

4. Product Status: Both parts maintain Active product status, ensuring long-term availability and manufacturing support.

5. Compliance Alignment: Both parts support RoHS3 compliance requirements. The substitute part's compliance status aligns with regulatory requirements for the main part.

Physical Compatibility: Dimensional variations between the two parts (width difference of 0.002" and height difference of 0.002") remain within standard 2512 package tolerances and do not affect PCB layout or assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the CRCW251210R2FKEGHP be used in place of the RC6432F10R2CS without circuit redesign?

A: Yes. The substitute part maintains identical resistance value (10.2 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and package format (2512). No circuit redesign is required. The increased power rating (1.5W versus 1W) is compatible with all applications designed for the original 1W specification.

Q: What is the significance of the higher power rating on the substitute part?

A: The 1.5W power rating on the CRCW251210R2FKEGHP provides additional thermal dissipation capacity compared to the 1W rating of the RC6432F10R2CS. This higher rating does not change circuit behavior but provides increased margin in applications where power dissipation approaches the component's thermal limits. Applications operating within the 1W specification of the original part remain fully compatible.

Q: Are there physical compatibility concerns with the dimensional differences?

A: No. The width difference of 0.002" (0.05mm) and height difference of 0.002" (0.04mm) between the two parts fall within standard manufacturing tolerances for the 2512 package specification. These variations do not affect PCB footprint compatibility, assembly processes, or mechanical fit.

Q: What does AEC-Q200 certification mean for non-automotive applications?

A: AEC-Q200 is an automotive industry qualification standard. For non-automotive applications, this certification has no impact on component performance or suitability. The CRCW251210R2FKEGHP functions identically to the RC6432F10R2CS in non-automotive circuits. The certification simply indicates the part meets additional automotive reliability and testing requirements.

Q: Are the packaging formats compatible?

A: The RC6432F10R2CS is supplied in standard packaging, while the CRCW251210R2FKEGHP is available in Cut Tape (CT) and Digi-Reel® formats. Both packaging types contain identical components. Packaging format selection depends on assembly process requirements (tape and reel for automated assembly, cut tape for manual or small-volume applications).

Q: Can these parts be mixed in the same production run?

A: Yes. Both parts are electrically and mechanically equivalent within the specified parameters. Mixing parts from different manufacturers in the same production run is acceptable provided assembly and testing processes accommodate the minor dimensional variations within 2512 package tolerances.

Q: What compliance standards apply to both parts?

A: Both the RC6432F10R2CS and CRCW251210R2FKEGHP are ROHS3 compliant. The substitute part carries additional AEC-Q200 automotive qualification. Both parts are REACH unaffected and classified under ECCN EAR99 for export purposes.
