Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F4420CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 442 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 2512 (6432 Metric)
• Number of terminations: 2
• Physical dimensions within tolerance

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

The identified substitutes maintain identical electrical specifications and package compatibility. Differences in packaging format (Tape & Reel vs. bulk) and additional certifications (AEC-Q200) represent enhancements rather than deviations from core specifications.

Engineering Selection Recommendations

AC2512FK-07442RL (YAGEO) - Upgrade Substitute:

This part qualifies as an upgrade substitute due to inclusion of AEC-Q200 automotive qualification in addition to all baseline specifications. The AC2512FK-07442RL maintains identical electrical parameters and 2512 package compatibility. Packaging is supplied in Tape & Reel format. Current inventory availability is 7702 pieces. This substitute is suitable for applications where automotive-grade reliability is beneficial or required.

CRCW2512442RFKEG (Vishay Dale) - Similar Substitute:

This part maintains full electrical and mechanical compatibility with identical resistance, tolerance, power rating, and temperature specifications. The CRCW2512442RFKEG includes AEC-Q200 automotive qualification. Physical dimensions remain within acceptable tolerance for 2512 package footprints. Packaging is supplied in Tape & Reel format. Current inventory availability is 4380 pieces. This substitute is suitable for direct replacement in existing designs.

Both substitutes carry ROHS3 compliance and MSL Level 1 rating, matching the original part's environmental and regulatory status.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-07442RL replace RC6432F4420CS in existing designs?

A: Yes. Both parts share identical electrical specifications (442 Ohms ±1%, 1W, ±100ppm/°C, -55°C to 155°C operating range) and 2512 package footprint. Physical dimensions are within standard tolerance for this package class. The AC2512FK-07442RL includes additional AEC-Q200 automotive qualification.

Q: What is the difference between the two substitute parts?

A: Both AC2512FK-07442RL and CRCW2512442RFKEG meet all electrical and mechanical requirements. Differences are limited to manufacturer (YAGEO vs. Vishay Dale), packaging format (both Tape & Reel), and minor dimensional variations within package tolerance. Both include AEC-Q200 certification.

Q: Are there packaging format differences between the main part and substitutes?

A: The RC6432F4420CS is specified with standard packaging. Both substitutes (AC2512FK-07442RL and CRCW2512442RFKEG) are supplied in Tape & Reel format. This difference affects handling and assembly processes but does not impact electrical or mechanical compatibility.

Q: Do all parts meet the same compliance standards?

A: Yes. The RC6432F4420CS, AC2512FK-07442RL, and CRCW2512442RFKEG are all ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity rating. The substitutes include additional AEC-Q200 automotive qualification.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: resistance value (442 Ohms), tolerance (±1%), power rating (1W), package type (2512), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). All identified substitutes meet these criteria.

Q: Can height differences affect PCB assembly?

A: Physical dimensions including height are within standard tolerance for the 2512 package class. RC6432F4420CS height is 0.026" (0.66mm), AC2512FK-07442RL is 0.026" (0.65mm), and CRCW2512442RFKEG is 0.028" (0.70mm). These variations are within acceptable limits for standard PCB assembly processes.
