Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS0805FT4R02 is determined by strict equivalence across the following critical parameters:

Electrical specifications must match exactly: 4.02 Ohms resistance value, ±1% tolerance, and 0.125W power rating. Temperature coefficient of ±200ppm/°C and operating temperature range of -55°C ~ 155°C must be maintained.

Mechanical compatibility requires identical package designation (0805 / 2012 Metric), physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), and maximum seated height (0.024" / 0.60mm). The component must feature two terminations in standard configuration.

Compliance and certification requirements include RoHS3 compliance, MSL 1 rating (unlimited moisture sensitivity), REACH Unaffected status, and Tape & Reel packaging format. Composition type (thick film) and termination technology must be compatible with the original design.

Parameter Comparison

Engineering Selection Recommendations

The RC0805FR-074R02L manufactured by YAGEO qualifies as a direct substitute for the RMCS0805FT4R02. Both components maintain Active product status and satisfy identical compliance requirements: RoHS3 certification, REACH Unaffected classification, and MSL 1 rating. Electrical and mechanical parameters are equivalent across all specified criteria, including resistance value, tolerance, power rating, temperature characteristics, and physical dimensions. The substitute part is available in the same Tape & Reel packaging format, supporting equivalent supply chain integration and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-074R02L be used as a direct replacement for RMCS0805FT4R02 in production?

A: Yes. Both parts meet identical electrical specifications (4.02 Ohms ±1%, 0.125W), mechanical dimensions (0805 package, 2.00mm x 1.25mm), and compliance certifications (RoHS3, REACH Unaffected, MSL 1). No design modifications are required.

Q: Are there differences in the thick film composition between these parts?

A: The RMCS0805FT4R02 features anti-sulfur composition, while the RC0805FR-074R02L features moisture-resistant composition. Both are thick film resistors with identical electrical performance and operating temperature range (-55°C ~ 155°C). The different protective features address different environmental conditions but do not affect substitution eligibility for standard applications.

Q: Do both parts support the same assembly and storage conditions?

A: Yes. Both components carry MSL 1 rating (unlimited moisture sensitivity), indicating no special moisture control requirements during storage or assembly. Both are supplied in Tape & Reel packaging and support standard pick-and-place assembly processes.

Q: What is the temperature coefficient significance for substitution?

A: Both parts maintain ±200ppm/°C temperature coefficient, ensuring equivalent resistance stability across the -55°C ~ 155°C operating range. This parameter must match for applications requiring predictable resistance behavior across temperature variations.

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. Compliance status is equivalent for all regulatory frameworks.
