Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F1403CS is determined by the following critical parameters:

Electrical Parameters: Resistance value (140 kOhms), tolerance (±1%), and power rating (0.25W) must be identical across all substitute parts.

Package Compatibility: All substitutes must use the 1206 (3216 Metric) package with 2 terminations to ensure PCB footprint compatibility and automated assembly compatibility.

Environmental & Compliance Parameters: Operating temperature range (-55°C ~ 155°C), temperature coefficient (±100ppm/°C), RoHS3 compliance, and MSL 1 rating are mandatory for direct substitution.

Composition: Thick film construction is maintained across all substitutes to preserve electrical performance characteristics.

Substitute parts are classified into two categories:

Direct Substitutes: Parts meeting all electrical, mechanical, and environmental specifications with identical or compatible feature sets (CR1206-FX-1403ELF, RC1206FR-07140KL).

Similar Substitutes: Parts meeting all core electrical and mechanical requirements but with additional certifications or feature variations (CRCW1206140KFKEA with AEC-Q200 automotive qualification, ERJ-8ENF1403V with AEC-Q200 qualification and Not For New Designs status).

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: CR1206-FX-1403ELF (Bourns Inc.) and RC1206FR-07140KL (YAGEO) are direct substitutes with Active product status. Both maintain identical electrical specifications and environmental ratings. Selection between these two is based on inventory availability and supply chain preferences.

For Automotive Applications: CRCW1206140KFKEA (Vishay Dale) is the appropriate selection when AEC-Q200 automotive qualification is required. This part maintains all core electrical and mechanical specifications while providing automotive-grade reliability certification. Product status is Active.

For Legacy System Maintenance: ERJ-8ENF1403V (Panasonic Electronic Components) meets all electrical and mechanical requirements with AEC-Q200 qualification. However, this part carries a "Not For New Designs" product status designation. Use this part only for replacement in existing systems where original part sourcing is exhausted.

Dimensional Considerations: All substitute parts maintain the 1206 package footprint. Minor variations in seated height (0.024" to 0.030") do not affect PCB assembly compatibility. Verify specific height constraints only if application involves space-limited designs.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-07140KL (YAGEO) be used as a direct replacement for RC3216F1403CS (Samsung)?

A: Yes. Both parts share identical resistance (140 kOhms), tolerance (±1%), power rating (0.25W), package (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1). Electrical and mechanical compatibility is confirmed.

Q: What is the difference between CR1206-FX-1403ELF and CRCW1206140KFKEA?

A: Both parts meet core electrical specifications. CRCW1206140KFKEA includes AEC-Q200 automotive qualification; CR1206-FX-1403ELF does not. Select CRCW1206140KFKEA for automotive applications requiring this certification. For non-automotive applications, either part is suitable.

Q: Why is ERJ-8ENF1403V marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) is not recommending this part for new product development. The part remains functionally equivalent and suitable for replacement in existing systems. For new designs, select from Active status alternatives: CR1206-FX-1403ELF, RC1206FR-07140KL, or CRCW1206140KFKEA.

Q: Are there package footprint differences between these substitutes?

A: All substitutes use the 1206 (3216 Metric) package with identical footprint dimensions. Seated height varies slightly (0.024" to 0.030" maximum), which is within standard PCB assembly tolerances and does not affect placement or soldering.

Q: Which substitute has the best inventory availability?

A: CR1206-FX-1403ELF (Bourns) has the highest inventory at 37,715 pieces, followed by ERJ-8ENF1403V (Panasonic) at 36,693 pieces. RC1206FR-07140KL (YAGEO) has 23,468 pieces available.

Q: Can I use CRCW1206140KFKEA in non-automotive applications?

A: Yes. AEC-Q200 qualification is a superset of standard industrial requirements. CRCW1206140KFKEA is fully compatible with non-automotive applications and provides enhanced reliability margins.
