Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RMC1/10-7R50FTP are qualified based on the following electrical and mechanical parameters:

Core Substitution Criteria:

• Resistance value: 7.5 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• Termination count: 2 (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The identified substitute parts RC0805FR-077R5L (YAGEO) and RMCF0805FT7R50 (Stackpole Electronics Inc) meet all core electrical and mechanical parameters. Differences in secondary characteristics such as temperature coefficient, specific features (moisture resistance, automotive qualification), and physical height variations do not preclude substitution when core parameters align.

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-077R5L (YAGEO): This substitute part meets all core electrical and mechanical parameters. The RC0805FR-077R5L features moisture-resistant thick film construction and maintains RoHS3 compliance. The temperature coefficient specification of ±200ppm/°C is tighter than the RMC1/10-7R50FTP. Physical height is 0.024" (0.60mm) compared to 0.026" (0.65mm) of the main part, which may be advantageous in space-constrained applications. Current inventory availability is 2170 pieces.

RMCF0805FT7R50 (Stackpole Electronics Inc): This substitute part meets all core electrical and mechanical parameters and carries AEC-Q200 automotive qualification. The RMCF0805FT7R50 is suitable for applications requiring automotive-grade reliability standards. Temperature coefficient is ±200ppm/°C. Physical dimensions and height match the main part exactly at 0.026" (0.65mm). RoHS3 compliance is confirmed. Current inventory availability is 5581 pieces.

Selection between substitute parts should be based on application requirements: YAGEO RC0805FR-077R5L for general-purpose applications with moisture resistance priority, or Stackpole RMCF0805FT7R50 for automotive applications requiring AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-077R5L replace RMC1/10-7R50FTP in any application? A: RC0805FR-077R5L meets all core electrical and mechanical parameters required for substitution. The 0.002" (0.05mm) height difference is within typical PCB assembly tolerances. Moisture-resistant construction provides additional environmental protection. Substitution is valid for applications where the core parameters (7.5 Ohms, ±1%, 1/8W, 0805 package) are the determining factors.

Q: What is the difference between RMCF0805FT7R50 and RMC1/10-7R50FTP? A: Both parts share identical electrical specifications (7.5 Ohms, ±1%, 1/8W) and package format (0805). The primary difference is that RMCF0805FT7R50 carries AEC-Q200 automotive qualification, making it suitable for automotive applications. Temperature coefficient is ±200ppm/°C versus -200/+500ppm/°C for the main part. Physical dimensions are identical.

Q: Are all three parts interchangeable on the same PCB? A: Yes. All three parts share identical resistance, tolerance, power rating, package type, and operating temperature range. Physical dimensions are equivalent within manufacturing tolerances. Substitution between any of these parts is valid from an electrical and mechanical standpoint.

Q: Does the temperature coefficient difference affect substitution? A: The temperature coefficient is a secondary parameter that does not preclude substitution when core parameters match. The RMC1/10-7R50FTP has a temperature coefficient of -200/+500ppm/°C, while both substitute parts specify ±200ppm/°C. Selection should consider application temperature stability requirements, but this difference does not invalidate substitution based on core parameters.

Q: Which substitute part has better availability? A: RMCF0805FT7R50 (Stackpole Electronics Inc) has the highest current inventory at 5581 pieces. RC0805FR-077R5L (YAGEO) has 2170 pieces available. The main part RMC1/10-7R50FTP has 813 pieces in stock.

Q: Can I use these parts in moisture-sensitive applications? A: All three parts carry Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. RC0805FR-077R5L includes explicit moisture-resistant construction. All parts are suitable for moisture-sensitive applications without special handling requirements.

Q: Are these parts RoHS compliant? A: RMC1/10-7R50FTP does not specify RoHS status in provided data. RC0805FR-077R5L and RMCF0805FT7R50 are both RoHS3 compliant. All parts are REACH Unaffected and classified as EAR99 for export control purposes.
