Parameter Comparison

Engineering Selection Recommendations

The RMCF2010FT150R is a direct substitute for the RPC2010KT150R in applications where component specifications align. Both parts are manufactured by Stackpole Electronics Inc and maintain identical electrical performance across the specified operating temperature range. Both components carry AEC-Q200 automotive qualification and ROHS3 compliance certification.

The primary distinction is tolerance specification. The RMCF2010FT150R provides ±1% tolerance compared to the RPC2010KT150R's ±10% tolerance. This tighter tolerance makes the RMCF2010FT150R suitable for precision-critical circuit designs while maintaining full compatibility with the original part's mechanical and thermal characteristics.

Physical dimensions remain consistent between both parts, with a negligible 0.002" (0.05mm) difference in maximum seated height. This minor variation does not impact PCB layout or assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT150R replace RPC2010KT150R in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package type, operating temperature range, and automotive qualification. The substitute offers improved tolerance specification without requiring design modifications.

Q: What is the significance of the tolerance difference?

A: The RPC2010KT150R has ±10% tolerance, meaning the actual resistance can vary between 135 Ohms and 165 Ohms. The RMCF2010FT150R has ±1% tolerance, with actual resistance between 148.5 Ohms and 151.5 Ohms. Applications requiring tighter resistance control benefit from the RMCF2010FT150R.

Q: Are there any physical compatibility concerns?

A: No. Both parts use the 2010 (5025 Metric) package with identical length and width dimensions. The maximum seated height differs by 0.002" (0.05mm), which is negligible for standard PCB assembly and does not affect component placement or clearance.

Q: Do both parts meet automotive standards?

A: Yes. Both the RPC2010KT150R and RMCF2010FT150R carry AEC-Q200 qualification and are suitable for automotive applications across the -55°C to 155°C operating temperature range.

Q: What is the moisture sensitivity rating?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity concerns during storage or handling.
