Substitute Part Grouping Explanation

Substitution eligibility for the RMCS0805FT5R11 is determined by strict equivalence across the following critical parameters:

• Resistance value: 5.11 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±200ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Physical dimensions: 0.079" L x 0.049" W / 2.00mm x 1.25mm (exact match required)
• Height - Seated (Max): 0.024" (0.60mm) (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (exact match required)

The RC0805FR-075R11L from YAGEO meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the RMCS0805FT5R11 and RC0805FR-075R11L are Active product status components with full ROHS3 compliance and REACH Unaffected certification. The RC0805FR-075R11L is designated as the manufacturer-recommended substitute and carries significantly higher inventory availability (73,538 units versus 907 units). Both parts satisfy identical electrical specifications, mechanical dimensions, and environmental operating parameters. Selection between these parts should be based on supply chain availability, lead time requirements, and packaging format preference (Tape & Reel for RMCS0805FT5R11 versus Cut Tape & Digi-Reel® for RC0805FR-075R11L).

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-075R11L be used as a direct replacement for RMCS0805FT5R11?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance values (5.11 Ohms ±1%), power ratings (0.125W), package dimensions (0805 / 2012 Metric), temperature coefficients (±200ppm/°C), and operating temperature ranges (-55°C ~ 155°C). Both meet ROHS3 compliance and REACH Unaffected requirements.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer (Stackpole Electronics Inc versus YAGEO), series designation (RMCS versus RC_L), protective features (anti-sulfur versus moisture resistant), and packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with PCB assembly?

A: No. Both parts share identical 0805 (2012 Metric) package specifications, physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), and maximum seated height (0.024" / 0.60mm). PCB footprints and assembly processes are fully compatible.

Q: Which part should be selected for new designs?

A: Selection should be based on supply chain strategy and availability. The RC0805FR-075R11L offers higher inventory levels and may provide better lead time performance. Both parts are Active status and suitable for production use.

Q: Do packaging format differences affect component performance?

A: No. Tape & Reel and Cut Tape & Digi-Reel® are packaging and delivery formats only. They do not affect electrical performance, reliability, or mechanical compatibility once components are mounted on the PCB.
