Substitute Part Grouping Explanation

Substitute parts for the RC6432F3742CS are identified based on strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Resistance value: 37.4 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)

The ERJ-1TNF3742U from Panasonic Electronic Components meets all primary substitution criteria. This part maintains identical electrical specifications and package compatibility while offering automotive-grade AEC-Q200 qualification. Physical dimensions show minor variations within acceptable tolerances for PCB footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

RC6432F3742CS (Samsung Electro-Mechanics):

• Primary selection for new designs requiring active production status
• Recommended for applications without automotive qualification requirements
• Current inventory availability: 822 pieces

ERJ-1TNF3742U (Panasonic Electronic Components):

• Suitable for direct substitution in existing designs currently using RC6432F3742CS
• Provides automotive-grade AEC-Q200 qualification for applications requiring enhanced reliability standards
• Product status is "Not For New Designs," indicating this part is in mature/legacy phase
• Higher inventory availability: 4802 pieces
• Packaging format: Tape & Reel (TR) for automated assembly processes

Both parts maintain identical electrical performance and thermal characteristics. Selection between them depends on production status requirements and automotive qualification needs for the end application.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF3742U replace RC6432F3742CS in existing designs?

A: Yes. Both parts share identical electrical specifications (37.4 kOhms ±1%, 1W, ±100ppm/°C) and operate across the same temperature range (-55°C ~ 155°C). Physical dimensions are compatible with standard 2512 PCB footprints. The ERJ-1TNF3742U provides additional AEC-Q200 automotive qualification.

Q: What are the physical dimension differences?

A: Length varies by 0.004" (0.10mm) and height by 0.002" (0.04mm). These differences fall within standard PCB design tolerances for 2512 package footprints and do not affect mechanical compatibility.

Q: Why is ERJ-1TNF3742U marked "Not For New Designs"?

A: This designation indicates the part is in mature production phase. Panasonic continues to supply existing inventory, but recommends alternative parts for new design starts. However, it remains a valid substitute for existing applications.

Q: What packaging formats are available?

A: RC6432F3742CS is supplied in standard packaging format. ERJ-1TNF3742U is available in Tape & Reel (TR) format, suitable for high-volume automated assembly operations.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC6432F3742CS and ERJ-1TNF3742U are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Which part should be selected for automotive applications?

A: ERJ-1TNF3742U includes AEC-Q200 automotive qualification. RC6432F3742CS does not specify automotive qualification. For automotive end-use, ERJ-1TNF3742U is the appropriate selection.
