Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F3483CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 348 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical criteria. Variations in physical dimensions (length, width, height) within standard manufacturing tolerances do not preclude substitution, provided the package designation remains 2512 (6432 Metric) and all electrical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

CRCW2512348KFKEG (Vishay Dale) is the primary substitute for new designs. This component maintains Active product status, carries AEC-Q200 automotive qualification, and is available in Tape & Reel packaging suitable for automated assembly processes. All electrical and thermal specifications align with the RC6432F3483CS.

ERJ-1TNF3483U (Panasonic Electronic Components) is classified as Not For New Designs. While electrical parameters and compliance certifications match the original component, this product status designation indicates Panasonic has discontinued active support for new applications. This part is suitable only for legacy system maintenance or replacement in existing designs where component continuity is required.

The RC6432F3483CS (Samsung Electro-Mechanics) remains the original specification component with Active status and moisture-resistant features optimized for general industrial applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512348KFKEG replace RC6432F3483CS in new designs?

A: Yes. The CRCW2512348KFKEG meets all electrical specifications (348 kOhms ±1%, 1W, ±100ppm/°C, -55°C ~ 155°C), maintains identical package designation (2512/6432 Metric), and holds Active product status with AEC-Q200 automotive qualification. Physical dimensions vary within standard manufacturing tolerances but do not affect functional compatibility.

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

A: The RC6432F3483CS features moisture-resistant characteristics for general industrial use. The CRCW2512348KFKEG carries AEC-Q200 automotive qualification, indicating enhanced reliability testing for automotive applications. Both are electrically and mechanically equivalent for the specified 348 kOhms ±1% 1W 2512 package.

Q: Why is ERJ-1TNF3483U marked "Not For New Designs"?

A: This designation indicates Panasonic has transitioned this product line and no longer actively supports new applications. The component remains electrically and mechanically compatible but should be used only for legacy system maintenance or replacement in existing designs.

Q: Are there packaging differences between these substitutes?

A: Yes. The RC6432F3483CS is supplied in bulk packaging. Both CRCW2512348KFKEG and ERJ-1TNF3483U are supplied in Tape & Reel (TR) format, which is standard for automated assembly. This difference does not affect electrical performance or mechanical fit.

Q: Do all three parts have identical physical dimensions?

A: Physical dimensions vary slightly within standard manufacturing tolerances. RC6432F3483CS and ERJ-1TNF3483U are 0.248" L × 0.126" W (6.30mm × 3.20mm). CRCW2512348KFKEG is 0.248" L × 0.124" W (6.30mm × 3.15mm). Height differences range from 0.026" to 0.028" (0.66mm to 0.70mm). All remain within 2512 package specification and are mechanically compatible.

Q: Are all parts RoHS3 compliant?

A: Yes. RC6432F3483CS, CRCW2512348KFKEG, and ERJ-1TNF3483U are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).
