Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3403CS is determined by the following mandatory parameters:

• Resistance Value: 340 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 Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within standard tolerances and differences in packaging format (Tape & Reel versus bulk) do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: CRCW1206340KFKEA (Vishay Dale) or RC1206FR-07340KL (YAGEO) are recommended for new designs. Both components maintain Active product status, ensuring long-term availability and supply chain stability. CRCW1206340KFKEA includes AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability. RC1206FR-07340KL provides moisture-resistant characteristics aligned with the original RCS3216F3403CS specification.

Secondary Selection: ERJ-8ENF3403V (Panasonic) is functionally equivalent but carries "Not For New Designs" product status. This component is suitable only for legacy system maintenance or repair applications where the original part is unavailable.

All substitute parts are ROHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206340KFKEA replace RCS3216F3403CS in existing designs?

A: Yes. Both components share identical electrical specifications (340 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C operating range) and package format (1206 / 3216 Metric). Physical dimension variations (height: 0.024" vs 0.026") are within standard PCB assembly tolerances and do not affect circuit performance or board layout.

Q: What is the difference between the substitute parts?

A: CRCW1206340KFKEA includes AEC-Q200 automotive qualification and is supplied in Tape & Reel packaging. ERJ-8ENF3403V also includes AEC-Q200 qualification but carries "Not For New Designs" status. RC1206FR-07340KL emphasizes moisture-resistant characteristics and is supplied in Tape & Reel format. All three are electrically and mechanically equivalent to the original part.

Q: Why is ERJ-8ENF3403V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends alternative parts for new circuit designs. The component remains functionally equivalent and suitable for replacement in existing applications or repair scenarios.

Q: Are there packaging format differences between substitute parts?

A: The main part RCS3216F3403CS is supplied in standard packaging. All substitute parts are supplied in Tape & Reel (TR) format, which is standard for high-volume SMD assembly. This format difference does not affect component functionality or electrical performance.

Q: Can these parts be used interchangeably in automotive applications?

A: CRCW1206340KFKEA and ERJ-8ENF3403V both carry AEC-Q200 automotive qualification. RC1206FR-07340KL does not specify automotive qualification. Component selection should align with application requirements and qualification standards.
