Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2262CS is determined by strict alignment with the following electrical and mechanical parameters:

Critical Parameters (Must Match Exactly):

• Resistance value: 22.6 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package designation: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: MSL 1
• RoHS compliance: ROHS3

Acceptable Variations:

• Manufacturer identity (different suppliers)
• Packaging format (Tape & Reel vs. bulk)
• Physical dimensions within 2512 package tolerance
• Additional certifications (e.g., AEC-Q200 automotive qualification)
• Product status (Active or Not For New Designs)

The two identified substitutes—CRCW251222K6FKEG (Vishay Dale) and ERJ-1TNF2262U (Panasonic Electronic Components)—meet all critical parameters and are therefore electrically and mechanically interchangeable with the RC6432F2262CS.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Applications: The CRCW251222K6FKEG (Vishay Dale) is the preferred substitute. It maintains active product status, carries AEC-Q200 automotive qualification, and offers the highest inventory availability (4390 units). This part is suitable for new designs and high-volume production environments.

For Existing Designs with Established Supply: The RC6432F2262CS (Samsung Electro-Mechanics) remains the primary choice with confirmed active status and adequate inventory (905 units).

For Automotive or Qualified Applications: Both CRCW251222K6FKEG and ERJ-1TNF2262U carry AEC-Q200 certification, making them suitable for automotive-grade applications. The Vishay Dale part is preferred due to active product status.

For Legacy or Maintenance Applications: The ERJ-1TNF2262U (Panasonic Electronic Components) is available with substantial inventory (8664 units) but carries "Not For New Designs" status. This part is suitable only for replacement or repair of existing assemblies where the original specification is maintained.

Compliance Considerations: All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. No additional regulatory barriers exist for substitution.

Frequently Asked Questions (FAQ)

Q: Can CRCW251222K6FKEG be used as a direct replacement for RC6432F2262CS?

A: Yes. Both parts share identical electrical specifications (22.6 kOhms, ±1%, 1W, ±100ppm/°C, -55°C to 155°C) and the same 2512 package. The primary difference is packaging format (Tape & Reel vs. bulk) and the addition of AEC-Q200 automotive certification on the Vishay part. No circuit redesign or PCB layout modification is required.

Q: What is the difference between the Samsung and Panasonic parts?

A: The RC6432F2262CS (Samsung) and ERJ-1TNF2262U (Panasonic) are electrically identical. The Panasonic part carries "Not For New Designs" status, indicating it is in mature or declining production phase. Physical dimensions vary slightly within 2512 package tolerance (Panasonic: 6.40mm L vs. Samsung: 6.30mm L). For new designs, the Vishay CRCW251222K6FKEG is recommended.

Q: Does the AEC-Q200 certification on the Vishay and Panasonic parts affect compatibility?

A: No. AEC-Q200 is an additional automotive qualification that does not restrict use in non-automotive applications. Parts with AEC-Q200 certification are fully compatible with designs that do not require automotive qualification. The certification represents a superset of standard performance requirements.

Q: Are there packaging considerations when switching between these parts?

A: Yes. The RC6432F2262CS is supplied in bulk packaging, while CRCW251222K6FKEG and ERJ-1TNF2262U are supplied in Tape & Reel format. This affects procurement, handling, and assembly processes but does not impact electrical or mechanical compatibility. PCB footprints and soldering procedures remain identical.

Q: Which part should be selected for a new automotive design?

A: The CRCW251222K6FKEG (Vishay Dale) is the appropriate choice. It combines active product status, AEC-Q200 automotive certification, and high inventory availability. This ensures long-term supply continuity and compliance with automotive qualification requirements.

Q: Can ERJ-1TNF2262U be used in new production designs?

A: The ERJ-1TNF2262U carries "Not For New Designs" status, indicating Panasonic does not recommend this part for new applications. While electrically compatible, this designation signals potential future discontinuation. New designs should specify either RC6432F2262CS or CRCW251222K6FKEG to ensure supply continuity.

Q: What is the significance of MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life under standard storage conditions (23°C, 50% relative humidity). No special moisture-control packaging or baking procedures are required before soldering. All three parts share this specification, ensuring identical handling requirements.
