LVC25JR100EV Equivalent & Substitute Parts

Part Overview

The LVC25JR100EV is a 100 mOhms ±5% 1W chip resistor in 2512 (6432 Metric) package manufactured by Ohmite. This thick film current sense resistor features moisture-resistant construction and operates across -40°C to 125°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters: resistance value (100 mOhms), package type (2512), composition (thick film), temperature coefficient (±100ppm/°C), and RoHS3 compliance. Tolerance and power rating variations are permitted within the substitute group based on application requirements. All substitute parts maintain the 2-termination configuration and moisture-resistant thick film construction.

The substitute parts are grouped into two categories:

Upgrade Path (Improved Tolerance): PT2512FK-070R1L, RL73H3AR10FTE, and RL73H3AR10FTDF offer ±1% tolerance with active product status, providing enhanced precision for current sense applications.

Higher Power Alternative: RHC2512JTR100 provides 2W power rating with ±5% tolerance and active status, suitable for applications requiring increased thermal headroom.

Parameter Comparison

Engineering Selection Recommendations

PT2512FK-070R1L (YAGEO): This part provides direct functional replacement with improved ±1% tolerance and extended operating temperature range (-55°C ~ 155°C). It carries AEC-Q200 automotive qualification and active product status, making it suitable for new designs requiring automotive-grade reliability.

RHC2512JTR100 (Stackpole Electronics Inc): Recommended for applications where increased power dissipation capacity is beneficial. The 2W rating provides thermal margin over the original 1W specification while maintaining ±5% tolerance and active product status.

RL73H3AR10FTE (TE Connectivity Passive Product): High-inventory alternative with ±1% tolerance, active status, and extended temperature range. Suitable for precision current sense applications requiring superior tolerance performance.

RL73H3AR10FTDF (TE Connectivity Passive Product): Functionally equivalent to RL73H3AR10FTE with identical electrical specifications and active product status. Selection between these two TE Connectivity variants depends on packaging and supply chain requirements.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and 2512 package compatibility with the original LVC25JR100EV.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with ±1% tolerance in place of the ±5% original?

A: Yes. The ±1% tolerance substitute parts (PT2512FK-070R1L, RL73H3AR10FTE, RL73H3AR10FTDF) provide tighter tolerance performance and are electrically compatible. This represents an upgrade path for applications requiring improved accuracy.

Q: Is the RHC2512JTR100 with 2W power rating a direct replacement?

A: The RHC2512JTR100 is mechanically and electrically compatible with identical resistance, tolerance, and package specifications. The increased 2W power rating does not prevent its use in 1W applications; it provides additional thermal headroom. Verify that board layout and thermal design accommodate the slightly different physical dimensions.

Q: What are the physical dimension differences between substitute parts?

A: All parts use the 2512 (6432 Metric) package with minor dimensional variations within tolerance. Length ranges from 0.248" to 0.250", width from 0.122" to 0.130", and height from 0.026" to 0.028". These variations are within standard PCB pad design tolerances and do not affect assembly compatibility.

Q: Does the extended temperature range of substitute parts affect my design?

A: The substitute parts operate across -55°C ~ 155°C compared to the original -40°C ~ 125°C. This extended range provides additional design margin and does not introduce compatibility issues. If your application operates within the original temperature range, all substitutes remain fully qualified.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental qualification.

Q: Which substitute should I select for automotive applications?

A: PT2512FK-070R1L carries AEC-Q200 automotive qualification and is the recommended choice for automotive-grade designs. Other substitutes are suitable for general industrial applications.
