LVC25JR510EV Equivalent & Substitute Parts

Part Overview

The LVC25JR510EV is a 510 mOhms ±5% 1W chip resistor in 2512 (6432 Metric) package manufactured by Ohmite. This thick film current sense resistor with moisture resistant properties operates across -40°C to 125°C and is RoHS3 compliant. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LVC25JR510EV is determined by the following critical parameters: resistance value (510 mOhms), package type (2512), composition (thick film), temperature coefficient (±100ppm/°C), and compliance certifications (RoHS3). Substitute parts must maintain the same resistance value and package footprint to ensure mechanical and electrical compatibility.

Tolerance and power rating variations are permitted within engineering design margins. Parts with improved tolerance (±1% versus ±5%) or higher power ratings (2W versus 1W) provide enhanced performance characteristics while maintaining functional equivalence. Operating temperature range extensions and additional certifications (AEC-Q200) represent upgrades that do not compromise compatibility.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with RoHS3 compliance, ensuring regulatory alignment and long-term availability compared to the obsolete LVC25JR510EV.

RCWE2512R510FKEA (Vishay Dale) provides the highest specification upgrade with ±1% tolerance, 2W power rating, and AEC-Q200 automotive qualification. This part is suitable for applications requiring automotive-grade reliability and extended temperature operation (-55°C to 155°C).

RHC2512FTR510 (Stackpole Electronics Inc) offers ±1% tolerance and 2W power rating with active product status and extended temperature range. This part maintains moisture resistant properties without automotive certification.

RHC2512JTR510 (Stackpole Electronics Inc) matches the original ±5% tolerance specification while providing 2W power rating and extended temperature range. This part represents a direct tolerance-equivalent upgrade with improved power handling.

RL73H3AR51FTDF and RL73H3AR51FTE (TE Connectivity Passive Product) both provide ±1% tolerance with 1W power rating matching the original power specification. Both parts feature current sense properties and extended temperature operation. RL73H3AR51FTE has higher inventory availability (15,519 pcs) compared to RL73H3AR51FTDF (2,888 pcs).

Frequently Asked Questions (FAQ)

Q: Can RCWE2512R510FKEA replace LVC25JR510EV in all applications?

A: RCWE2512R510FKEA is mechanically and electrically compatible as a direct substitute. The 2512 package footprint is identical, resistance value matches, and all compliance certifications are met. The improved tolerance (±1% versus ±5%) and higher power rating (2W versus 1W) represent performance enhancements that do not create compatibility issues.

Q: What is the difference between the Stackpole RHC2512FTR510 and RHC2512JTR510 options?

A: Both parts share identical package, resistance, temperature coefficient, and operating range specifications. The primary difference is tolerance: RHC2512FTR510 provides ±1% tolerance while RHC2512JTR510 maintains ±5% tolerance matching the original part. Both offer 2W power rating and moisture resistant properties.

Q: Are the TE Connectivity RL73H3AR51FTDF and RL73H3AR51FTE interchangeable?

A: Yes, both parts are functionally identical with matching resistance, tolerance, power rating, package, and operating specifications. The difference is packaging format and inventory availability. RL73H3AR51FTE has significantly higher stock (15,519 pcs versus 2,888 pcs).

Q: Does the extended operating temperature range (-55°C to 155°C) of substitute parts affect compatibility with the original -40°C to 125°C specification?

A: No. Extended temperature range represents an upgrade that maintains full compatibility. Applications designed for -40°C to 125°C operation function identically with parts rated to -55°C to 155°C.

Q: Is AEC-Q200 certification required for non-automotive applications?

A: AEC-Q200 certification is not required for non-automotive applications. RCWE2512R510FKEA includes this certification as an additional qualification. For general industrial and consumer applications, parts without automotive certification (RHC2512 series, RL73H3 series) are fully suitable.

Q: Can I use a 2W rated part in place of the original 1W specification?

A: Yes. Higher power rating provides additional thermal margin and does not create compatibility issues. The 2512 package dimensions remain identical, and electrical characteristics are preserved. This represents a performance upgrade suitable for applications with higher current or thermal stress.
