Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F8251CS is determined by strict alignment of the following critical parameters:

Electrical Specifications:

• Resistance value: 8.25 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Specifications:

• Package format: 2512 (6432 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 2512 footprint

Compliance & Environmental:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)
• Composition: Thick film

The CRCW25128K25FKEG from Vishay Dale meets all substitution criteria, with identical electrical parameters and package specifications. The substitute part includes additional automotive AEC-Q200 qualification, which does not restrict its use in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F8251CS and CRCW25128K25FKEG are Active product status components with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts should be based on:

Availability and Supply Chain: The CRCW25128K25FKEG currently maintains higher inventory (1963 pcs) compared to the RC6432F8251CS (725 pcs), making it suitable for applications where supply continuity is a priority.

Packaging Format: The RC6432F8251CS is supplied in standard packaging, while the CRCW25128K25FKEG is available in Tape & Reel (TR) format, which is preferred for automated assembly processes.

Automotive Applications: The CRCW25128K25FKEG carries AEC-Q200 automotive qualification. This certification does not restrict use in non-automotive circuits and provides additional qualification documentation for applications requiring automotive-grade component traceability.

Dimensional Tolerance: Both parts conform to the 2512 package standard. Minor dimensional variations (width: 3.20mm vs 3.15mm; height: 0.66mm vs 0.70mm) remain within standard PCB footprint tolerances and do not affect circuit performance or board layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CRCW25128K25FKEG directly replace the RC6432F8251CS in existing designs?

A: Yes. Both parts share identical electrical specifications (8.25 kOhms ±1%, 1W, ±100ppm/°C), operate across the same temperature range (-55°C to 155°C), and conform to the 2512 package standard. The PCB footprint and circuit behavior remain unchanged.

Q: What is the significance of the AEC-Q200 rating on the CRCW25128K25FKEG?

A: AEC-Q200 is an automotive industry qualification standard. This certification indicates the part has undergone additional reliability testing for automotive environments. The rating does not restrict the component's use in non-automotive applications and simply provides enhanced qualification documentation.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within standard tolerances. The CRCW25128K25FKEG has a maximum seated height of 0.028" (0.70mm) compared to 0.026" (0.66mm) for the RC6432F8251CS, and a width of 3.15mm versus 3.20mm. These differences remain within 2512 package specifications and do not affect PCB layout compatibility.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both the RC6432F8251CS and CRCW25128K25FKEG are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What packaging formats are available?

A: The RC6432F8251CS is supplied in standard packaging. The CRCW25128K25FKEG is available in Tape & Reel (TR) format, which is optimized for automated pick-and-place assembly operations.

Q: Are both parts ROHS3 compliant?

A: Yes. Both components meet ROHS3 compliance requirements and are REACH Unaffected, making them suitable for applications with environmental and regulatory compliance requirements.
