RMCS1206FT23R7 Equivalent & Substitute Parts

Part Overview

The RMCS1206FT23R7 is a 23.7 Ohm ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This thick film resistor features anti-sulfur construction and operates across -55°C to 155°C. The part is currently active in production. Substitute parts may be required due to inventory availability, supply chain considerations, or specific application requirements such as automotive qualification or enhanced moisture resistance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT23R7 is determined by the following critical parameters:

• Resistance value: 23.7 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• RoHS3 compliance and MSL 1 rating (required for regulatory and environmental compatibility)

All identified substitute parts meet these core electrical and mechanical parameters. Variations exist in manufacturing features (automotive AEC-Q200 qualification, moisture resistance enhancements) and physical dimensions within acceptable tolerances for the 1206 package form factor.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are electrically and mechanically equivalent to the RMCS1206FT23R7 based on core parameters. Selection should be based on product status and application requirements:

CRCW120623R7FKEA (Vishay Dale) is recommended for applications requiring automotive-grade components. This part carries AEC-Q200 qualification and maintains active production status, making it suitable for new designs in automotive and high-reliability applications.

RC1206FR-0723R7L (YAGEO) is suitable for general-purpose applications requiring moisture-resistant construction. This part maintains active production status and is appropriate for new designs in standard industrial and consumer applications.

ERJ-8ENF23R7V (Panasonic Electronic Components) carries AEC-Q200 automotive qualification but is designated "Not For New Designs." This part should be used only for legacy system maintenance or replacement applications where the original specification requires Panasonic components.

Frequently Asked Questions (FAQ)

Q: Can CRCW120623R7FKEA be used as a direct replacement for RMCS1206FT23R7?

A: Yes. Both parts share identical electrical specifications (23.7 Ohms ±1%, 0.25W, ±100ppm/°C) and operate across -55°C to 155°C. Physical dimensions are within acceptable tolerances for the 1206 package. The CRCW part includes automotive AEC-Q200 qualification, which provides additional reliability assurance without compromising compatibility.

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

A: Anti-sulfur construction (RMCS1206FT23R7) protects against sulfur-containing atmospheric corrosion. Moisture-resistant construction (RC1206FR-0723R7L) provides enhanced protection against humidity and moisture ingress. Both are thick film resistors with equivalent electrical performance. Feature selection depends on environmental exposure conditions in the application.

Q: Why is ERJ-8ENF23R7V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends alternative parts for new product designs. The part remains available for existing applications and legacy system support but should not be selected for new designs due to potential future availability constraints.

Q: Are all substitute parts suitable for automated assembly?

A: Yes. All parts are supplied in Tape & Reel (TR) packaging and are compatible with standard surface mount assembly equipment. Physical dimensions across all parts are within the 1206 package specification tolerance, ensuring consistent pick-and-place and reflow performance.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH unaffected. Compliance certifications are equivalent across all options.
