Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1431CS is determined by strict alignment with the following electrical and mechanical parameters:

Electrical Parameters (Non-negotiable):

• Resistance value: 1.43 kOhms
• Tolerance: ±1% (tighter tolerances acceptable)
• Power rating: 1W (higher ratings acceptable)
• Temperature coefficient: ±100ppm/°C (lower values acceptable)
• Operating temperature range: -55°C to 155°C (extended ranges acceptable)

Mechanical Parameters (Non-negotiable):

• Package format: 2512 (6432 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters:

• RoHS3 Compliant status required
• Moisture Sensitivity Level 1 acceptable

The substitute part ERJ-1TNF1431U meets all electrical and mechanical requirements. Dimensional variations within manufacturing tolerances are acceptable provided the part fits the PCB footprint and assembly process specifications.

Engineering Selection Recommendations

Primary Part (RC6432F1431CS): The Samsung Electro-Mechanics RC6432F1431CS maintains Active product status and is the preferred selection for new designs. With 857 units in current inventory, this part provides supply continuity and long-term availability assurance.

Substitute Part (ERJ-1TNF1431U): The Panasonic ERJ-1TNF1431U is electrically and mechanically equivalent with identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. The part carries Automotive AEC-Q200 qualification, indicating enhanced reliability for demanding applications.

However, the ERJ-1TNF1431U carries "Not For New Designs" status, restricting its use to legacy system support, field replacements, or applications where existing qualification documentation permits its use. The dimensional variations (length 6.40mm vs. 6.30mm, height 0.70mm vs. 0.66mm) fall within standard PCB footprint tolerances but require verification against specific board layout constraints.

Selection Criteria:

• Use RC6432F1431CS for new designs and applications requiring long-term supply assurance
• Use ERJ-1TNF1431U only when RC6432F1431CS is unavailable and design documentation permits substitution of parts with "Not For New Designs" status
• Verify PCB footprint compatibility when substituting, particularly for high-density layouts

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF1431U be used as a direct replacement for RC6432F1431CS in new product designs?

A: No. The ERJ-1TNF1431U carries "Not For New Designs" status. New designs must use the RC6432F1431CS. The ERJ-1TNF1431U is restricted to legacy system support and field replacements where existing design documentation permits its use.

Q: Are the dimensional differences between these parts significant?

A: The dimensional variations are minor: length differs by 0.1mm (6.40mm vs. 6.30mm) and height by 0.04mm (0.70mm vs. 0.66mm). These differences fall within standard PCB footprint tolerances. However, verification against specific board layout constraints is required, particularly for high-density applications or boards with tight component spacing.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both RC6432F1431CS and ERJ-1TNF1431U are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8533.21.0030).

Q: What is the difference between the "Moisture Resistant" feature of the Samsung part and the "Automotive AEC-Q200" feature of the Panasonic part?

A: These are different feature designations. "Moisture Resistant" indicates construction designed to resist moisture ingress. "Automotive AEC-Q200" is an automotive industry qualification standard indicating the part meets enhanced reliability and testing requirements for automotive applications. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Can I use the ERJ-1TNF1431U in existing products currently using RC6432F1431CS?

A: Yes, for field replacements and legacy system support. The electrical and mechanical parameters are equivalent. However, this substitution must be documented and approved through your design change control process. Verify that your existing design documentation and qualification testing permit use of parts with "Not For New Designs" status.

Q: What packaging formats are available for these parts?

A: RC6432F1431CS is supplied in standard packaging (specific format not detailed in provided data). ERJ-1TNF1431U is supplied in Tape & Reel (TR) format. Confirm packaging requirements with your procurement specifications before ordering.

Q: Are there other substitute parts available for the RC6432F1431CS?

A: The provided data lists ERJ-1TNF1431U as the primary substitute. The ERJ-1TNF1431U data references additional substitutes (CRCW25121K43FKTG, RC2512FK-071K43L, AC2512FK-071K43L, CRCW25121K43FKEG, RMCF2512FT1K43), but detailed specifications for these parts are not included in the current reference data.
