Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F302CS is determined by strict alignment with the following parameters:

Mandatory Matching Criteria:

• Resistance value: 3 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Allowable Variations:

• Manufacturer identity (different suppliers)
• Packaging format (Tape & Reel vs. bulk)
• Physical dimensions within 2512 package tolerance (length 0.248"–0.252", width 0.122"–0.126", height 0.026"–0.028")
• Additional certifications (AEC-Q200 automotive qualification)
• Product status (Active or Not For New Designs)

All identified substitutes meet these criteria and are electrically and mechanically interchangeable with the main part.

Parameter Comparison

Engineering Selection Recommendations

RC2512FK-073KL (YAGEO): Direct equivalent with active product status. Identical electrical and mechanical specifications. Highest compatibility for standard industrial applications. Largest available inventory among non-automotive variants.

RMCF2512FT3K00 (Stackpole Electronics Inc): Direct equivalent with active product status and AEC-Q200 automotive qualification. Suitable for automotive and high-reliability applications requiring automotive-grade components. Largest inventory availability (43767 units).

ERJ-1TNF3001U (Panasonic Electronic Components): Functionally equivalent with AEC-Q200 automotive qualification. Product status is "Not For New Designs," indicating this part is in mature/legacy phase. Suitable for replacement and maintenance applications only; not recommended for new circuit designs.

For new designs requiring standard industrial-grade specifications, RC2512FK-073KL or RMCF2512FT3K00 are preferred. For automotive applications, RMCF2512FT3K00 is the recommended active substitute. ERJ-1TNF3001U is suitable only for legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-073KL replace RC6432F302CS directly? A: Yes. Both parts share identical electrical specifications (3 kOhms ±1%, 1W), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and package (2512). Physical dimensions are within tolerance. Direct substitution is valid.

Q: What is the difference between the automotive-rated parts and the standard parts? A: ERJ-1TNF3001U and RMCF2512FT3K00 carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and testing standards. RC6432F302CS and RC2512FK-073KL do not specify automotive qualification. Automotive-rated parts are required for automotive circuit applications; standard parts are suitable for industrial and consumer applications.

Q: Why is ERJ-1TNF3001U marked "Not For New Designs"? A: This product status indicates the part is in mature/legacy phase. Panasonic continues to supply existing inventory but does not recommend this part for new circuit designs. Use RMCF2512FT3K00 or RC2512FK-073KL for new designs instead.

Q: Are there packaging differences between these substitutes? A: RC6432F302CS is supplied in standard packaging (not specified). RC2512FK-073KL, ERJ-1TNF3001U, and RMCF2512FT3K00 are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly; conversion to bulk or alternative packaging may require special order.

Q: Do all substitutes meet RoHS and REACH compliance? A: Yes. All four parts are ROHS3 compliant and REACH unaffected. All carry MSL 1 (Unlimited) moisture sensitivity rating, requiring no special handling or baking procedures.

Q: What are the physical dimension tolerances for the 2512 package? A: Length ranges 0.248"–0.252" (6.30mm–6.35mm). Width ranges 0.122"–0.126" (3.10mm–3.20mm). Height ranges 0.026"–0.028" (0.65mm–0.70mm). All listed substitutes fall within these tolerances and are PCB-compatible.

Q: Which substitute has the best inventory availability? A: RMCF2512FT3K00 (Stackpole) has the highest inventory at 43767 units, followed by RC2512FK-073KL (YAGEO) at 13357 units and ERJ-1TNF3001U (Panasonic) at 8618 units.
