Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RMC1/8-7R15FTP are qualified based on the following critical parameters:

Electrical Equivalence: Resistance value of 7.15 Ohms with ±1% tolerance and 0.25W power rating must be maintained across all substitute candidates.

Package Compatibility: All substitute parts must utilize the 1206 (3216 Metric) surface mount package with 2 terminations to ensure mechanical fit and soldering compatibility on printed circuit boards.

Thermal Performance: Operating temperature range of -55°C ~ 155°C must be supported by substitute components to maintain functional reliability across specified environmental conditions.

Composition and Construction: Thick film resistor construction is required to preserve electrical characteristics and performance consistency.

Moisture and Environmental Compliance: Moisture Sensitivity Level 1 (Unlimited) classification and REACH Unaffected status must be maintained.

The following substitute parts meet all specified criteria:

1. RC1206FR-077R15L (YAGEO) – Moisture Resistant variant
2. RMCF1206FT7R15 (Stackpole Electronics Inc) – Automotive AEC-Q200 variant

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-077R15L (YAGEO) is suitable for applications requiring moisture-resistant thick film construction. This substitute maintains electrical equivalence with the RMC1/8-7R15FTP while offering enhanced moisture resistance characteristics. ROHS3 compliance and REACH Unaffected status align with modern regulatory requirements. This variant is appropriate for general industrial and commercial applications where moisture protection is beneficial.

RMCF1206FT7R15 (Stackpole Electronics Inc) is qualified for automotive and high-reliability applications through AEC-Q200 certification. This substitute provides equivalent electrical performance with automotive-grade qualification. ROHS3 compliance and REACH Unaffected status support automotive supply chain requirements. This variant is appropriate for automotive, aerospace, and mission-critical applications requiring AEC-Q200 qualification.

Both substitute parts maintain full electrical and mechanical compatibility with the RMC1/8-7R15FTP across all specified operating parameters. Selection between substitutes depends on application-specific requirements: moisture resistance for general use or automotive AEC-Q200 qualification for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-077R15L replace RMC1/8-7R15FTP in any application?

A: RC1206FR-077R15L maintains electrical equivalence (7.15 Ohms ±1%, 0.25W) and mechanical compatibility (1206 package, 2 terminations) with RMC1/8-7R15FTP. The substitute operates across the same temperature range (-55°C ~ 155°C) and maintains MSL 1 classification. Substitution is valid for applications where moisture-resistant thick film construction is acceptable.

Q: What is the difference between the temperature coefficients of these parts?

A: RMC1/8-7R15FTP specifies -200 / +500 ppm/°C temperature coefficient. RC1206FR-077R15L and RMCF1206FT7R15 both specify ±200 ppm/°C. The substitute parts offer more symmetrical temperature coefficient performance across the operating range.

Q: Is RMCF1206FT7R15 suitable for non-automotive applications?

A: RMCF1206FT7R15 is electrically and mechanically equivalent to RMC1/8-7R15FTP and functions in any application within the specified operating parameters. AEC-Q200 certification indicates automotive-grade reliability but does not restrict use in non-automotive applications.

Q: Are there physical dimension differences between these parts?

A: RMC1/8-7R15FTP measures 0.122" L x 0.063" W (3.10mm x 1.60mm) with 0.025" maximum seated height. RC1206FR-077R15L measures 0.122" L x 0.063" W (3.10mm x 1.60mm) with 0.026" maximum seated height. RMCF1206FT7R15 measures 0.126" L x 0.063" W (3.20mm x 1.60mm) with 0.028" maximum seated height. All parts fit the 1206 package footprint; minor height variations do not affect standard PCB assembly processes.

Q: Do all three parts have the same moisture sensitivity classification?

A: All three parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: What compliance certifications apply to each part?

A: RMC1/8-7R15FTP: REACH Unaffected, EAR99. RC1206FR-077R15L: ROHS3 Compliant, REACH Unaffected, EAR99. RMCF1206FT7R15: ROHS3 Compliant, AEC-Q200, REACH Unaffected, EAR99.
