LVM25FVR025E-TR Equivalent & Substitute Parts

Part Overview

The LVM25FVR025E-TR is a 25 milliohm, ±1% tolerance, 1W chip resistor manufactured by Ohmite in the 2512 (6432 Metric) package. This metal foil current sense resistor is designed for precision current measurement applications and is currently in active production status. Substitute parts are identified when inventory constraints, lead time requirements, or specific application certifications necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LVM25FVR025E-TR is permissible when the alternative part maintains the following critical parameters:

• Resistance value: 25 mOhms
• Tolerance: ±1%
• Package: 2512 (6432 Metric)
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C to 170°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS compliance status

The PE2512FKE7W0R025L qualifies as a direct substitute based on these parameters. While this part features a higher power rating (2W versus 1W) and metal film composition (versus metal foil), these characteristics represent functional enhancements that do not compromise compatibility in applications designed for the original 1W specification.

Parameter Comparison

Engineering Selection Recommendations

Both the LVM25FVR025E-TR and PE2512FKE7W0R025L are active production parts with full RoHS compliance. The PE2512FKE7W0R025L carries AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade reliability standards. The higher power rating of the YAGEO part (2W) provides additional thermal margin in current sense applications without altering electrical performance at the specified 1W operating point. Selection between these parts should be based on availability, lead time, and whether automotive qualification is required for the end application.

Frequently Asked Questions (FAQ)

Q: Can the PE2512FKE7W0R025L replace the LVM25FVR025E-TR in all applications?

A: Yes. Both parts share identical resistance, tolerance, temperature coefficient, and operating temperature range. The 2512 package dimensions are equivalent, and both maintain MSL 1 moisture sensitivity. The higher power rating of the substitute part does not create compatibility issues in circuits designed for 1W operation.

Q: What is the significance of the AEC-Q200 certification on the YAGEO part?

A: AEC-Q200 is an automotive industry qualification standard. This certification indicates the PE2512FKE7W0R025L has undergone additional reliability testing and is approved for automotive applications. If your application does not require automotive qualification, this certification is not a limiting factor for substitution.

Q: Are there dimensional differences between these parts?

A: Both parts use the 2512 (6432 Metric) package. Dimensional specifications are nearly identical: LVM25FVR025E-TR measures 0.252" L × 0.126" W (6.40mm × 3.20mm), while PE2512FKE7W0R025L measures 0.250" L × 0.125" W (6.35mm × 3.18mm). These minor variations fall within standard PCB footprint tolerances and do not affect board-level compatibility.

Q: Does the metal foil versus metal film composition affect substitution?

A: Both compositions meet the specified ±1% tolerance and ±50ppm/°C temperature coefficient. The metal film composition of the substitute part is functionally equivalent for current sense applications within the stated operating parameters.

Q: Are both parts RoHS compliant?

A: Yes. The LVM25FVR025E-TR is RoHS Compliant, and the PE2512FKE7W0R025L is ROHS3 Compliant. Both meet RoHS requirements for restricted substance elimination.
