RMCS1206FT237K Equivalent & Substitute Parts

Part Overview

The RMCS1206FT237K is a 237 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This anti-sulfur resistor operates across -55°C to 155°C with a temperature coefficient of ±100ppm/°C and is ROHS3 compliant. Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements mandate specific manufacturer certifications such as automotive AEC-Q200 qualification or alternative packaging formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT237K is determined by strict equivalence across the following parameters: resistance value (237 kOhms), tolerance (±1%), power rating (0.25W), package type (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99). All four substitute parts meet these core electrical and mechanical requirements. Variations in physical dimensions (length, width, height) and specific feature sets (anti-sulfur, moisture resistant, automotive AEC-Q200) do not preclude substitution but may influence selection based on application-specific environmental or regulatory needs.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are electrically and mechanically equivalent to the RMCS1206FT237K and maintain full compliance with ROHS3, REACH, and EAR99 requirements.

CR1206-FX-2373ELF (Bourns Inc.) and RC1206FR-07237KL (YAGEO) are recommended for general-purpose applications requiring moisture-resistant thick film construction with active product status and standard commercial availability.

CRCW1206237KFKEA (Vishay Dale) is recommended for automotive and harsh-environment applications requiring AEC-Q200 qualification with active product status and high inventory availability.

ERJ-8ENF2373V (Panasonic Electronic Components) meets automotive AEC-Q200 requirements but carries a "Not For New Designs" product status designation. This part is suitable only for legacy system maintenance or replacement applications where design continuity is required.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RMCS1206FT237K with any of these parts in my design?

A: Yes, all four substitute parts are electrically and mechanically equivalent. They share identical resistance (237 kOhms), tolerance (±1%), power rating (0.25W), package type (1206), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Physical dimension variations are within acceptable tolerances for 1206 package specifications.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur construction (RMCS1206FT237K) protects against sulfur-containing atmospheric corrosion. Moisture-resistant construction (CR1206-FX-2373ELF, RC1206FR-07237KL) provides protection against humidity and moisture ingress. Both are thick film resistors with MSL 1 (Unlimited) ratings. Feature selection depends on specific environmental exposure conditions.

Q: Should I use the Panasonic ERJ-8ENF2373V if it has "Not For New Designs" status?

A: The ERJ-8ENF2373V is suitable only for replacement or maintenance of existing systems already using this part number. For new designs, select from CR1206-FX-2373ELF (Bourns), CRCW1206237KFKEA (Vishay Dale), or RC1206FR-07237KL (YAGEO), all with active product status.

Q: Are automotive AEC-Q200 parts required for my application?

A: AEC-Q200 qualification (CRCW1206237KFKEA, ERJ-8ENF2373V) is mandatory only for automotive and safety-critical applications. For general industrial or consumer electronics, standard commercial-grade parts (CR1206-FX-2373ELF, RC1206FR-07237KL) are appropriate.

Q: What packaging options are available?

A: RMCS1206FT237K, CR1206-FX-2373ELF, ERJ-8ENF2373V, and RC1206FR-07237KL are supplied in Tape & Reel (TR) format. CRCW1206237KFKEA is available in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on assembly equipment compatibility and procurement volume requirements.
