Substitute Part Grouping Explanation

Substitution of the RC6432F4532CS is determined by strict equivalence across the following critical parameters:

• Resistance Value: 45.3 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 1W (exact match required)
• Package Format: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Termination Count: 2 (exact match required)
• RoHS Compliance: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity: MSL 1 (minimum requirement)

The identified substitute part ERJ-1TNF4532U meets all electrical and mechanical parameters. Physical dimensions show minor variations within acceptable tolerances for the 2512 package format. The substitute part carries automotive AEC-Q200 qualification, which represents an additional certification beyond the base requirement.

Parameter Comparison

Engineering Selection Recommendations

RC6432F4532CS (Samsung Electro-Mechanics) is suitable for applications requiring an active production status component with moisture-resistant thick film construction. This part is appropriate for general industrial and commercial applications with standard environmental requirements.

ERJ-1TNF4532U (Panasonic Electronic Components) provides equivalent electrical and mechanical performance with the addition of automotive AEC-Q200 qualification. However, this part carries a "Not For New Designs" product status designation. Selection of this substitute should be limited to legacy system support, replacement inventory, or applications where automotive-grade qualification is specifically required and the product status restriction is acceptable.

For new design implementations, the RC6432F4532CS remains the primary selection. For automotive applications or systems requiring AEC-Q200 certification, alternative active-status parts meeting the specified parameters should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF4532U be used as a direct replacement for RC6432F4532CS?

A: Yes, ERJ-1TNF4532U meets all electrical and mechanical parameters required for direct substitution. Physical dimensions vary slightly within acceptable tolerances for the 2512 package format. The substitute part includes automotive AEC-Q200 qualification as an additional feature.

Q: What is the significance of the "Not For New Designs" status on ERJ-1TNF4532U?

A: This designation indicates that Panasonic does not recommend this part for new product development. The part remains available for existing applications and legacy system support. New designs should prioritize active-status alternatives.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. RC6432F4532CS measures 0.248" L × 0.126" W × 0.026" H (max). ERJ-1TNF4532U measures 0.252" L × 0.126" W × 0.028" H (max). These variations fall within standard 2512 package tolerances and do not affect PCB layout compatibility.

Q: Do both parts meet the same compliance requirements?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. ERJ-1TNF4532U includes additional automotive AEC-Q200 qualification.

Q: What packaging formats are available?

A: RC6432F4532CS is supplied in standard packaging. ERJ-1TNF4532U is supplied in Tape & Reel (TR) format, which may affect procurement and handling procedures.

Q: Are the temperature coefficients identical?

A: Yes, both parts specify ±100ppm/°C temperature coefficient and operate across the identical temperature range of -55°C to 155°C.
