Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3743CS is determined by the following mandatory parameters:

• Resistance Value: 374 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.25W / 1/4W (exact match required)
• Package / Case: 1206 (3216 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)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: CRCW1206374KFKEA (Vishay Dale) or RC1206FR-07374KL (YAGEO) are recommended for new designs. Both parts maintain Active product status and provide full electrical and mechanical compatibility with the RCS3216F3743CS. CRCW1206374KFKEA includes AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability. RC1206FR-07374KL offers equivalent performance without automotive-specific certification.

Alternative Selection: ERJ-8ENF3743V (Panasonic) provides complete electrical and mechanical equivalence but carries Not For New Designs product status. This part is suitable for replacement or repair applications only and should not be selected for new circuit designs.

Compliance Considerations: All substitute parts are ROHS3 compliant and REACH unaffected, matching the environmental and regulatory status of the main part number.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206374KFKEA replace RCS3216F3743CS in existing circuits?

A: Yes. CRCW1206374KFKEA meets all electrical specifications (374 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C) and mechanical requirements (1206 package, 3.20mm x 1.60mm dimensions). Direct substitution is valid.

Q: What is the difference between ERJ-8ENF3743V and the other substitutes?

A: ERJ-8ENF3743V carries Not For New Designs product status, indicating the manufacturer has discontinued active development. Electrical and mechanical parameters are identical to other substitutes. Use only for repair or replacement of existing assemblies.

Q: Are there dimensional differences between substitute parts?

A: All parts use 1206 (3216 Metric) package. Minor height variations exist: RCS3216F3743CS (0.66mm max), CRCW1206374KFKEA (0.60mm max), ERJ-8ENF3743V (0.70mm max), RC1206FR-07374KL (0.65mm max). These variations are within standard PCB assembly tolerances and do not affect interchangeability.

Q: Which substitute is best for automotive applications?

A: CRCW1206374KFKEA includes AEC-Q200 automotive qualification. ERJ-8ENF3743V also carries AEC-Q200 rating but is Not For New Designs. For new automotive designs, CRCW1206374KFKEA is the appropriate selection.

Q: Do all substitutes have the same moisture sensitivity rating?

A: Yes. All parts including RCS3216F3743CS, CRCW1206374KFKEA, ERJ-8ENF3743V, and RC1206FR-07374KL are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
