Substitute Part Grouping Explanation

Substitution of the CPF0201B511RE with CPF0201B511RE1 is based on electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical selection criteria: resistance value of 511 Ohms, tolerance of ±0.1%, power rating of 0.03W (1/32W), thin film composition, temperature coefficient of ±25ppm/°C, operating temperature range of -55°C to 155°C, and 0201 (0603 Metric) package format with matching physical dimensions and termination count. Both components maintain ROHS3 compliance and MSL 1 rating. The substitute part is qualified for direct replacement where the original part number is unavailable or where supply chain optimization is required.

Parameter Comparison

Engineering Selection Recommendations

Both CPF0201B511RE and CPF0201B511RE1 are active production components from TE Connectivity Passive Product with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts is determined by inventory availability and supply chain requirements rather than performance differentiation. The substitute part CPF0201B511RE1 provides equivalent functional performance in all circuit applications where the original part number is specified. Both components are suitable for use in precision analog circuits, measurement instrumentation, and applications requiring tight tolerance resistors with low temperature coefficient performance. The MSL 1 rating indicates unlimited shelf life under standard storage conditions for both parts.

Frequently Asked Questions (FAQ)

Q: Can CPF0201B511RE1 be used as a direct replacement for CPF0201B511RE?

A: Yes. Both parts are electrically and mechanically identical with matching resistance value (511 Ohms), tolerance (±0.1%), power rating (0.03W), temperature coefficient (±25ppm/°C), operating temperature range (-55°C to 155°C), and 0201 package format. Direct substitution is applicable in all circuit designs.

Q: Are there any differences in compliance or certification between these parts?

A: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. The primary difference is REACH status documentation, with CPF0201B511RE1 designated as REACH Unaffected. This does not affect functional equivalence or circuit performance.

Q: What is the significance of the 0201 package format?

A: The 0201 (0603 Metric) package is a surface-mount chip resistor measuring 0.023" L x 0.011" W (0.58mm x 0.29mm) with a maximum seated height of 0.011" (0.28mm). Both substitute parts share identical package dimensions and termination configuration, ensuring compatibility with existing PCB layouts and assembly processes.

Q: Are these parts suitable for high-precision applications?

A: Yes. Both CPF0201B511RE and CPF0201B511RE1 are thin film resistors with ±0.1% tolerance and ±25ppm/°C temperature coefficient, making them suitable for precision analog circuits, measurement instrumentation, and applications requiring stable resistor performance across the operating temperature range.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Unlimited) indicates that these components have unlimited shelf life under standard storage conditions and do not require special moisture control or baking procedures prior to assembly. This simplifies inventory management and reduces handling requirements.
