Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC6432J364CS is based on the following allowed parameters:

Electrical Parameters (Must Match):

• Resistance value: 360 kOhms
• Power rating: 1W minimum
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum

Mechanical Parameters (Must Match):

• Package type: 2512 (6432 Metric)
• Composition: Thick Film
• Number of terminations: 2
• Moisture resistance: Required

Compliance Parameters (Must Match or Exceed):

• RoHS3 compliance
• MSL 1 rating
• REACH unaffected status

Tolerance Consideration: Tolerance variations (±5% vs ±1%) are permitted when the substitute part offers equal or tighter tolerance, as this does not compromise circuit performance.

Product Status Consideration: Substitute parts with "Not For New Designs" status are listed for reference in legacy system maintenance and repair scenarios only.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - RC2512JK-07360KL (YAGEO):

The RC2512JK-07360KL is the direct equivalent substitute for the RC6432J364CS. Both parts share identical electrical specifications (360 kOhms, ±5% tolerance, 1W, ±100ppm/°C), mechanical compatibility (2512 package, thick film composition), and compliance certifications (ROHS3, MSL 1). The YAGEO part maintains Active product status and offers higher inventory availability (9024 pieces). The primary difference is packaging format (Tape & Reel vs. Bulk), which does not affect electrical or mechanical performance. This substitute is suitable for all new designs and production applications.

Alternative Substitute - ERJ-1TNF3603U (Panasonic):

The ERJ-1TNF3603U provides an alternative with improved tolerance specification (±1% vs. ±5%), maintaining all other critical parameters including 360 kOhms resistance, 1W power rating, 2512 package, and -55°C to 155°C operating range. This part includes AEC-Q200 automotive qualification and is ROHS3 compliant with MSL 1 rating. However, the ERJ-1TNF3603U carries "Not For New Designs" product status, restricting its use to legacy system maintenance, repair, and field replacement scenarios only. The tighter tolerance may provide performance benefits in precision applications but does not justify new design adoption given the discontinued status.

Selection Criteria:

• For new designs and production: Use RC2512JK-07360KL (YAGEO) as the primary substitute
• For legacy system maintenance: ERJ-1TNF3603U (Panasonic) is available for repair applications where AEC-Q200 qualification is beneficial
• For continued original sourcing: RC6432J364CS (Samsung) remains the primary part with confirmed Active status

All three parts are ROHS3 compliant, MSL 1 rated, and suitable for -55°C to 155°C operating environments.

Frequently Asked Questions (FAQ)

Q: Can RC2512JK-07360KL replace RC6432J364CS directly on the PCB?

A: Yes. Both parts use the 2512 (6432 Metric) package with identical footprint dimensions and two terminations. Physical and electrical compatibility is confirmed. The only difference is packaging format (Tape & Reel vs. Bulk), which does not affect board-level installation.

Q: What is the tolerance difference between RC6432J364CS and ERJ-1TNF3603U?

A: RC6432J364CS has ±5% tolerance, while ERJ-1TNF3603U has ±1% tolerance. The ±1% specification is tighter and provides better resistance value accuracy. Both tolerances are acceptable for the 360 kOhms specification, but ERJ-1TNF3603U offers superior precision if required by circuit design.

Q: Why is ERJ-1TNF3603U marked "Not For New Designs"?

A: This designation indicates the part is in end-of-life status and Panasonic does not recommend it for new product development. It remains available for existing system support and field repairs. New designs should use RC2512JK-07360KL (YAGEO) or RC6432J364CS (Samsung).

Q: Are all three parts ROHS3 compliant?

A: Yes. RC6432J364CS, RC2512JK-07360KL, and ERJ-1TNF3603U are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All three meet current environmental and regulatory requirements.

Q: What is the temperature coefficient specification and why does it matter?

A: All three parts have ±100ppm/°C temperature coefficient. This specification defines how the resistance value changes with temperature. A ±100ppm/°C coefficient means the resistance will shift approximately 0.01% per degree Celsius change. This is consistent across all substitutes and suitable for standard industrial applications.

Q: Can I use these parts in automotive applications?

A: RC6432J364CS and RC2512JK-07360KL are standard industrial-grade parts. ERJ-1TNF3603U includes AEC-Q200 automotive qualification. If automotive-grade certification is required, ERJ-1TNF3603U is the only qualified option, though it is restricted to legacy applications due to "Not For New Designs" status.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel (TR) packaging is used for automated assembly lines with pick-and-place equipment. Bulk packaging is used for manual assembly or smaller production runs. Both formats contain the same electrical component; packaging choice depends on manufacturing process requirements, not electrical performance.

Q: Are dimensional variations between parts significant?

A: Dimensional variations are minimal and within acceptable PCB footprint tolerances. RC6432J364CS: 6.30mm L x 3.20mm W; RC2512JK-07360KL: 6.35mm L x 3.10mm W; ERJ-1TNF3603U: 6.40mm L x 3.20mm W. All fit the standard 2512 footprint. Height differences (0.66mm to 0.70mm) are negligible for board-level clearance.

Q: Which substitute has the best inventory availability?

A: RC2512JK-07360KL (YAGEO) has 9024 pieces in stock, compared to 1152 pieces for RC6432J364CS and 2536 pieces for ERJ-1TNF3603U. YAGEO offers the highest availability for immediate procurement.
