RMCS1206FT36K5 Equivalent & Substitute Parts

Part Overview

The RMCS1206FT36K5 is a 36.5 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. Equivalent and substitute parts are identified to support design flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when alternative manufacturers' specifications better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT36K5 is determined by strict equivalence across the following critical parameters:

• Resistance value: 36.5 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)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Composition: Thick Film (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All four substitute parts listed meet these criteria. Variations in physical dimensions (length, width, height) within the 1206 package specification, feature differences (anti-sulfur vs. moisture resistant vs. automotive AEC-Q200), and product status do not affect functional substitutability for this resistor category.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the RMCS1206FT36K5 based on electrical and mechanical parameters. Selection among these alternatives should be guided by the following considerations:

Active Production Status: CR1206-FX-3652ELF (Bourns), CRCW120636K5FKEA (Vishay Dale), and RC1206FR-0736K5L (YAGEO) are all in active production. ERJ-8ENF3652V (Panasonic) carries a "Not For New Designs" status, indicating it is suitable for replacement or repair of existing assemblies but not recommended for new product development.

Compliance and Certifications: CRCW120636K5FKEA and ERJ-8ENF3652V include automotive AEC-Q200 qualification, making them suitable for automotive applications requiring this certification. CR1206-FX-3652ELF and RC1206FR-0736K5L are specified as moisture resistant, providing enhanced environmental protection in humid or corrosive conditions.

Inventory Availability: RC1206FR-0736K5L (YAGEO) offers the highest inventory level at 156,303 pieces, followed by CRCW120636K5FKEA (Vishay Dale) at 19,912 pieces, ERJ-8ENF3652V (Panasonic) at 38,676 pieces, and CR1206-FX-3652ELF (Bourns) at 13,851 pieces.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for RMCS1206FT36K5?

A: Yes. All four substitute parts meet the critical electrical and mechanical specifications: 36.5 kOhms ±1% resistance, 0.25W power rating, 1206 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, thick film composition, ROHS3 compliance, and MSL 1 rating. They are electrically and mechanically interchangeable.

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

A: Anti-sulfur composition (RMCS1206FT36K5) is designed to resist degradation from sulfur-containing environments. Moisture-resistant features (CR1206-FX-3652ELF, RC1206FR-0736K5L) provide protection against humidity and moisture ingress. Both are thick film resistors with identical electrical specifications. Feature selection depends on the specific environmental conditions of the application.

Q: Should I use ERJ-8ENF3652V if it is marked "Not For New Designs"?

A: ERJ-8ENF3652V is suitable for replacement, repair, or maintenance of existing assemblies. For new product development, select from CR1206-FX-3652ELF, CRCW120636K5FKEA, or RC1206FR-0736K5L, which are all in active production status.

Q: Are the automotive AEC-Q200 qualified parts suitable for non-automotive applications?

A: Yes. CRCW120636K5FKEA and ERJ-8ENF3652V meet automotive AEC-Q200 qualification, which includes rigorous reliability and quality testing. These parts are suitable for any application, including non-automotive, and their automotive qualification does not restrict their use.

Q: Do physical dimension variations affect substitutability?

A: No. All parts conform to the 1206 (3216 Metric) package specification. Minor variations in length, width, and height (within the 1206 specification tolerance) do not affect PCB layout compatibility or functional performance. Verify PCB footprint design accommodates the 1206 package standard.

Q: What is MSL 1 rating and why is it important?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life with no moisture precautions required. All listed parts carry MSL 1 rating, meaning they can be stored and handled without special moisture control measures, simplifying inventory management and reducing handling costs.
