Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for PTC thermistors is determined by the following critical parameters: nominal resistance value, resistance tolerance, operating temperature range, package dimensions, and mounting type. The PRF15BF102RB6RC can be substituted by parts that maintain the same 1 kOhms nominal resistance, 0402 (1005 Metric) surface mount package, and compatible operating temperature specifications.

The TPM0S102P075RT meets the core functional requirements of matching resistance value and package form factor. However, substitution must account for differences in resistance tolerance and maximum operating temperature, which may affect circuit performance in specific applications.

Parameter Comparison

Engineering Selection Recommendations

The TPM0S102P075RT is an active product from Murata Electronics and serves as a functional substitute for the PRF15BF102RB6RC in applications where the operating temperature does not exceed 100°C. Both components share identical nominal resistance values and package specifications, enabling direct physical replacement on PCBs designed for 0402 surface mount thermistors.

Selection between these parts should be based on application temperature requirements. The PRF15BF102RB6RC supports operation up to 160°C, while the TPM0S102P075RT is limited to 100°C maximum. Additionally, the PRF15BF102RB6RC provides tighter resistance tolerance (±5%) compared to the TPM0S102P075RT (±50%), which may be critical in precision temperature sensing circuits.

Both components are RoHS compliant and suitable for standard manufacturing processes. The TPM0S102P075RT's active status provides better long-term availability compared to the Last Time Buy status of the PRF15BF102RB6RC.

Frequently Asked Questions (FAQ)

Q: Can the TPM0S102P075RT replace the PRF15BF102RB6RC in all applications?

A: Physical replacement is possible due to matching package and mounting specifications. However, functional compatibility depends on application temperature requirements. If the circuit operates above 100°C, the TPM0S102P075RT is not suitable. Additionally, the wider resistance tolerance of the TPM0S102P075RT may affect precision applications requiring ±5% tolerance.

Q: What are the key differences between these two parts?

A: The primary differences are operating temperature range (PRF15BF102RB6RC: -40°C to 160°C; TPM0S102P075RT: -40°C to 100°C), resistance tolerance (PRF15BF102RB6RC: ±5%; TPM0S102P075RT: ±50%), and product status (PRF15BF102RB6RC: Last Time Buy; TPM0S102P075RT: Active).

Q: Are both parts from the same manufacturer?

A: Yes, both the PRF15BF102RB6RC and TPM0S102P075RT are manufactured by Murata Electronics.

Q: Will the TPM0S102P075RT fit the same PCB footprint?

A: Yes, both components use the 0402 (1005 Metric) surface mount package and are compatible with identical PCB layouts.

Q: Which part should I select for new designs?

A: For new designs, the TPM0S102P075RT is recommended due to its Active product status, ensuring long-term availability. However, if your application requires operation above 100°C or demands ±5% resistance tolerance, alternative solutions should be evaluated.
