RMCS0805FT3R32 Equivalent & Substitute Parts

Part Overview

The RMCS0805FT3R32 is a 3.32 Ohm ±1% 0.125W chip resistor in 0805 (2012 Metric) package manufactured by Stackpole Electronics Inc. This thick film resistor features anti-sulfur construction and is designed for general-purpose applications requiring precision resistance values in compact form factors. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when original inventory is unavailable or when alternative sourcing is required while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RMCS0805FT3R32 are qualified based on strict equivalence of the following electrical and mechanical parameters:

• Resistance value: 3.32 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package type: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Height - Seated (Max): 0.024" (0.60mm)
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The RC0805FR-073R32L from YAGEO meets all these criteria and is classified as a manufacturer-recommended substitute. Variations in surface features (anti-sulfur vs. moisture resistant) do not affect substitution eligibility when all electrical and mechanical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

Both the RMCS0805FT3R32 and RC0805FR-073R32L are active production parts with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability and supply chain requirements. The RC0805FR-073R32L offers significantly higher inventory availability (45,689 pcs vs. 887 pcs) and is available in Cut Tape and Digi-Reel packaging formats. Both parts meet identical electrical specifications, mechanical dimensions, and environmental operating requirements. No performance degradation occurs when substituting between these parts in applications requiring 3.32 Ohm ±1% 0.125W resistors in 0805 package format.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-073R32L be used as a direct replacement for RMCS0805FT3R32?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance values (3.32 Ohms ±1%), power ratings (0.125W), package dimensions (0805 / 2012 Metric), temperature coefficients (±200ppm/°C), and operating ranges (-55°C ~ 155°C). Both are RoHS3 compliant with MSL 1 rating.

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

A: Anti-sulfur and moisture resistant are surface protection features that do not affect the core electrical or mechanical performance of the resistor. Both formulations maintain identical electrical characteristics and are suitable for standard PCB assembly and operating environments.

Q: Are the packaging formats interchangeable?

A: The RMCS0805FT3R32 is supplied in Tape & Reel (TR) format, while the RC0805FR-073R32L is available in Cut Tape (CT) and Digi-Reel formats. All formats contain the same component with identical specifications. Packaging format selection depends on assembly equipment and production volume requirements.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications.
