RMCS1206FT2K37 Equivalent & Substitute Parts

Part Overview

The RMCS1206FT2K37 is a 2.37 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This thick film resistor features anti-sulfur composition and is designed for general-purpose applications requiring precision resistance values with tight tolerance specifications. The part is currently in active production status. Substitute parts may be required due to supply chain constraints, regional availability, or specific application requirements such as automotive qualification or enhanced moisture resistance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT2K37 is determined by the following critical parameters:

• Resistance value: 2.37 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Package: 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: MSL 1 (exact match required)

All four substitute parts meet these criteria. Variations in secondary features such as moisture resistance enhancement, automotive qualification, or dimensional tolerances do not affect functional substitutability within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are electrically and mechanically equivalent to the RMCS1206FT2K37 based on the specified parameters. Selection should be based on the following factors:

CR1206-FX-2371ELF (Bourns Inc.) and RC1206FR-072K37L (YAGEO) are recommended for new designs due to active product status and moisture-resistant composition. RC1206FR-072K37L offers the highest inventory availability at 124,679 pieces.

CRCW12062K37FKEA (Vishay Dale) is suitable for applications requiring automotive AEC-Q200 qualification with active product status and 15,369 pieces in stock.

ERJ-8ENF2371V (Panasonic Electronic Components) carries automotive AEC-Q200 qualification but is designated "Not For New Designs," making it suitable only for legacy system maintenance or replacement applications where the original specification must be maintained.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the RMCS1206FT2K37?

A: Yes. All four substitute parts meet the critical electrical and mechanical parameters: 2.37 kOhms resistance, ±1% tolerance, 0.25W power rating, 1206 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, ROHS3 compliance, and MSL 1 moisture sensitivity. They are functionally equivalent for circuit applications.

Q: What is the difference between the anti-sulfur feature of the RMCS1206FT2K37 and the moisture-resistant features of the substitutes?

A: Both anti-sulfur and moisture-resistant compositions are protective features in thick film resistors. The specific composition difference does not affect the electrical parameters or substitutability within the defined specification range.

Q: Should I select the Panasonic ERJ-8ENF2371V if it has automotive AEC-Q200 qualification?

A: The ERJ-8ENF2371V is designated "Not For New Designs." It should be used only for replacement or maintenance of existing systems where the original part specification must be preserved. For new designs, select CR1206-FX-2371ELF, CRCW12062K37FKEA, or RC1206FR-072K37L.

Q: Are there packaging differences that affect PCB assembly?

A: The RMCS1206FT2K37 is supplied in Tape & Reel (TR) packaging. RC1206FR-072K37L is supplied in Cut Tape (CT) & Digi-Reel format. CR1206-FX-2371ELF and CRCW12062K37FKEA are supplied in Tape & Reel. Packaging format does not affect component performance but may influence procurement and assembly logistics.

Q: Which substitute part has the best availability?

A: RC1206FR-072K37L (YAGEO) has the highest inventory with 124,679 pieces in stock, followed by CR1206-FX-2371ELF (Bourns) with 23,738 pieces and CRCW12062K37FKEA (Vishay Dale) with 15,369 pieces.
