Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8-5R11FTP is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 5.11 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package format: 1206 (3216 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Temperature coefficient may differ within acceptable engineering margins
• Physical dimensions may vary within standard 1206 package tolerances
• Manufacturer-specific features (moisture resistance, automotive qualification) do not disqualify substitution when core electrical and mechanical parameters match

The identified substitute parts RC1206FR-075R11L (YAGEO) and RMCF1206FT5R11 (Stackpole Electronics Inc) meet all critical matching parameters and are therefore qualified as direct equivalents.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-075R11L (YAGEO): This substitute is qualified for applications requiring moisture-resistant thick film construction. YAGEO RC_L series components maintain identical electrical specifications and standard 1206 package dimensions. Product status is Active with 58929 pieces in inventory. RoHS3 compliance is confirmed.

RMCF1206FT5R11 (Stackpole Electronics Inc): This substitute is qualified for automotive applications requiring AEC-Q200 qualification. Stackpole RMCF series components meet all electrical specifications with Active product status and 10899 pieces in inventory. RoHS3 compliance is confirmed. Physical dimensions show minor variation within 1206 package tolerance (length 3.20mm vs 3.10mm, height 0.70mm vs 0.65mm).

Both substitutes are suitable for direct replacement based on matching resistance, tolerance, power rating, package format, operating temperature range, and moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-075R11L replace RMC1/8-5R11FTP in all applications?

A: Yes. Both components share identical resistance (5.11 Ohms), tolerance (±1%), power rating (0.25W), package format (1206), composition (thick film), operating temperature range (-55°C ~ 155°C), and moisture sensitivity level (1). The moisture-resistant feature of the YAGEO part does not prevent substitution.

Q: Can RMCF1206FT5R11 replace RMC1/8-5R11FTP in all applications?

A: Yes. Both components share identical electrical specifications and package classification (1206). Physical dimensions vary within standard 1206 package tolerances (length 3.20mm vs 3.10mm, height 0.70mm vs 0.65mm). The AEC-Q200 automotive qualification of the Stackpole part does not prevent substitution in non-automotive applications.

Q: What is the significance of temperature coefficient differences?

A: The RMC1/8-5R11FTP specifies -200/+500ppm/°C while both substitutes specify ±200ppm/°C. Both temperature coefficients fall within acceptable thick film resistor performance ranges for the -55°C ~ 155°C operating window. Selection between parts should consider specific circuit temperature stability requirements.

Q: Are all three parts available in Tape & Reel packaging?

A: Yes. RMC1/8-5R11FTP, RC1206FR-075R11L, and RMCF1206FT5R11 are all supplied in Tape & Reel (TR) format, enabling direct substitution in automated assembly processes.

Q: What compliance certifications apply to these parts?

A: All three components are REACH Unaffected and classified under ECCN EAR99. RC1206FR-075R11L and RMCF1206FT5R11 are RoHS3 Compliant. RMCF1206FT5R11 carries AEC-Q200 automotive qualification.
