Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RMCS1206FT2K61 are qualified based on the following criteria:

• Identical resistance value: 2.61 kOhms
• Identical tolerance: ±1%
• Identical power rating: 0.25W (1/4W)
• Identical package: 1206 (3216 Metric)
• Identical composition: Thick Film
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical RoHS and REACH compliance status
• Identical MSL rating: 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in additional features (automotive AEC-Q200 qualification, moisture resistance enhancements) do not affect functional interchangeability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are functionally equivalent to the RMCS1206FT2K61 for standard applications requiring a 2.61 kOhms ±1% 1206 thick film resistor.

For new designs, select from parts with Active product status: AC1206FR-072K61L, CR1206-FX-2611ELF, CRCW12062K61FKEA, RC1206FR-072K61L, or RC3216F2611CS.

For automotive applications requiring AEC-Q200 qualification, use AC1206FR-072K61L, CRCW12062K61FKEA, or ERJ-8ENF2611V.

For applications requiring enhanced moisture resistance without automotive qualification, use CR1206-FX-2611ELF, RC1206FR-072K61L, or RC3216F2611CS.

The ERJ-8ENF2611V carries Not For New Designs status and should be used only for legacy system maintenance or replacement applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these parts directly into a circuit designed for RMCS1206FT2K61?

A: Yes. All listed substitute parts share identical electrical specifications (2.61 kΩ ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and are packaged in the 1206 (3216 Metric) form factor. Physical dimensions vary slightly within the 1206 specification, but these variations do not affect PCB footprint compatibility or electrical performance.

Q: What is the difference between parts with and without AEC-Q200 qualification?

A: AEC-Q200 qualification indicates the part meets automotive industry reliability and quality standards. Parts with AEC-Q200 (AC1206FR-072K61L, CRCW12062K61FKEA, ERJ-8ENF2611V) are suitable for automotive applications. Parts without this qualification (CR1206-FX-2611ELF, RC1206FR-072K61L, RC3216F2611CS) are suitable for general industrial and consumer applications.

Q: Why is ERJ-8ENF2611V marked as "Not For New Designs"?

A: This product status indicates the manufacturer has discontinued active development and recommends alternative parts for new circuit designs. ERJ-8ENF2611V remains available for existing product support and legacy system maintenance.

Q: Are all these parts RoHS3 compliant?

A: Yes. All listed parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts can be stored indefinitely without special moisture control measures and do not require baking before soldering.
