Substitute Part Grouping Explanation

Substitute parts for the RC1005J8R2CS are qualified based on the following criteria:

Electrical Equivalence: All substitute parts maintain identical resistance value (8.2 Ohms), tolerance (±5%), and power rating (0.063W / 1/16W).

Mechanical Compatibility: All substitutes use the 0402 (1005 Metric) package format with matching physical dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm) and maximum seated height (0.016" / 0.40mm).

Environmental Specifications: All substitutes operate within the same temperature range (-55°C to 155°C) and maintain MSL 1 (Unlimited) moisture sensitivity rating.

Compliance Standards: All substitutes are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with matching HTSUS code 8533.21.0030.

Composition: All substitutes use thick film construction with moisture-resistant characteristics.

Substitutes differ in manufacturer identity, temperature coefficient specifications, and specialized certifications (automotive AEC-Q200 qualification for specific alternatives).

Parameter Comparison

Engineering Selection Recommendations

RC0402JR-078R2L (YAGEO): This substitute provides direct electrical and mechanical equivalence with improved temperature coefficient performance (±200ppm/°C versus ±300ppm/°C). YAGEO RC_L series maintains full ROHS3 compliance and MSL 1 rating. Selection is appropriate for applications requiring enhanced temperature stability within standard industrial specifications.

RMCF0402JT8R20 (Stackpole Electronics Inc): This substitute adds AEC-Q200 automotive qualification to the base electrical and mechanical specifications. Temperature coefficient matches YAGEO at ±200ppm/°C. Selection is appropriate for automotive applications, harsh environment deployments, or designs requiring automotive-grade component reliability. ROHS3 compliance and MSL 1 rating are maintained.

All three parts maintain Active product status and full compliance with ROHS3, REACH, and export classification requirements. Selection between alternatives depends on application environment (standard industrial versus automotive), temperature stability requirements, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can RC0402JR-078R2L replace RC1005J8R2CS in any application?

A: Yes. Both parts share identical electrical specifications (8.2 Ohms ±5%, 0.063W), mechanical dimensions (0402 package), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1). The YAGEO part offers improved temperature coefficient (±200ppm/°C versus ±300ppm/°C), making it suitable for all applications where the Samsung part is specified.

Q: What is the difference between RC0402JR-078R2L and RMCF0402JT8R20?

A: Both parts are electrically and mechanically equivalent with matching temperature coefficients (±200ppm/°C). The primary difference is that RMCF0402JT8R20 carries AEC-Q200 automotive qualification. Selection depends on application requirements: use YAGEO for standard industrial applications; use Stackpole for automotive or mission-critical applications requiring automotive-grade reliability.

Q: Are all three parts interchangeable in PCB assembly?

A: Yes. All three parts use identical 0402 (1005 Metric) package format with matching physical dimensions (0.039" L x 0.020" W, 0.016" maximum seated height) and two terminations. PCB footprints, pick-and-place programming, and reflow profiles are identical across all three parts.

Q: Does temperature coefficient difference affect circuit performance?

A: Temperature coefficient affects resistance stability across temperature extremes. RC1005J8R2CS has ±300ppm/°C; RC0402JR-078R2L and RMCF0402JT8R20 have ±200ppm/°C. For applications operating across the full -55°C to 155°C range, the lower temperature coefficient of YAGEO and Stackpole parts provides improved resistance stability. For applications with limited temperature variation, the difference is negligible.

Q: Are moisture sensitivity levels identical across all three parts?

A: Yes. All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Storage, handling, and assembly processes are identical for all three parts.

Q: Which part should be selected for new designs?

A: For standard industrial applications, RC0402JR-078R2L offers improved temperature coefficient performance with equivalent compliance. For automotive or harsh environment applications, RMCF0402JT8R20 provides AEC-Q200 qualification. Both are preferred over RC1005J8R2CS for new designs due to superior temperature stability and equivalent availability.
