Equivalent & Substitute Parts for LVC25FR100EV

Part Overview

The LVC25FR100EV is a 100 mOhms ±1% 1W chip resistor in 2512 (6432 Metric) package manufactured by Ohmite. This thick film current sense resistor is designed for moisture-resistant applications with a temperature coefficient of ±100ppm/°C and operating range of -40°C to 125°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LVC25FR100EV is determined by strict equivalence across the following parameters: resistance value (100 mOhms), tolerance (±1%), power rating (1W), package type (2512), composition (thick film), temperature coefficient (±100ppm/°C), and compliance certifications (ROHS3, MSL 1). All substitute parts listed maintain these core electrical and mechanical specifications, ensuring direct functional compatibility in current sense applications.

The substitute parts are grouped as follows:

Upgrade Substitute: PT2512FK-070R1L (YAGEO) — Active product with automotive AEC-Q200 qualification and extended operating temperature range (-55°C to 155°C).

Manufacturer Recommended Substitutes: RL73H3AR10FTE and RL73H3AR10FTDF (TE Connectivity Passive Product) — Active products with extended operating temperature range (-55°C to 155°C) and REACH compliance.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are electrically and mechanically equivalent to the LVC25FR100EV and are suitable for direct replacement in current sense applications. Selection among substitutes should be based on product availability and compliance requirements:

PT2512FK-070R1L is recommended for automotive applications requiring AEC-Q200 qualification. This part provides the widest operating temperature range (-55°C to 155°C) and is actively manufactured by YAGEO.

RL73H3AR10FTE is recommended for general industrial applications. This TE Connectivity part has the highest inventory availability (103,994 pcs) and is actively produced with REACH compliance.

RL73H3AR10FTDF is recommended as an alternative TE Connectivity option with identical electrical specifications and REACH compliance, suitable for applications where specific packaging or supplier requirements apply.

All substitutes maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with moisture-sensitive manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can RL73H3AR10FTE and RL73H3AR10FTDF be used interchangeably with LVC25FR100EV?

A: Yes. Both TE Connectivity parts are electrically and mechanically equivalent to the LVC25FR100EV. They share identical resistance (100 mOhms), tolerance (±1%), power rating (1W), package type (2512), and composition (thick film). The primary difference is packaging format (Tape & Reel) and extended operating temperature range (-55°C to 155°C versus -40°C to 125°C).

Q: What is the difference between PT2512FK-070R1L and the RL73 series substitutes?

A: PT2512FK-070R1L is manufactured by YAGEO and includes automotive AEC-Q200 qualification. The RL73 series parts are manufactured by TE Connectivity. All three maintain identical core electrical specifications. Selection depends on automotive qualification requirements and supplier preference.

Q: Are there dimensional differences between the substitute parts?

A: Minor dimensional variations exist in width and height specifications. LVC25FR100EV: 0.250" L × 0.130" W (6.35mm × 3.30mm), height 0.026" (0.65mm). PT2512FK-070R1L: 0.250" L × 0.126" W (6.35mm × 3.20mm), height 0.026" (0.65mm). RL73H3AR10FTE and RL73H3AR10FTDF: 0.250" L × 0.122" W (6.35mm × 3.10mm), height 0.028" (0.70mm). These variations are within standard 2512 package tolerances and do not affect PCB layout compatibility.

Q: Do all substitute parts meet RoHS and MSL requirements?

A: Yes. All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original LVC25FR100EV specifications.

Q: Which substitute part has the best availability?

A: RL73H3AR10FTE has the highest inventory availability at 103,994 pcs in stock, followed by PT2512FK-070R1L at 4,189 pcs and RL73H3AR10FTDF at 1,818 pcs.
