LVC25JR620EV Equivalent & Substitute Parts

Part Overview

The LVC25JR620EV is a 620 mOhms ±5% 1W chip resistor in 2512 (6432 Metric) package manufactured by Ohmite. This thick film current sense resistor features moisture resistance and operates across -40°C to 125°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility while meeting current supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters: resistance value (620 mOhms), package type (2512), composition (thick film), and current sense functionality. Tolerance, power rating, and operating temperature range may vary within acceptable engineering limits for equivalent parts.

The substitute parts are grouped as follows:

Upgrade Category (Enhanced Specifications): RCWE2512R620FKEA provides improved tolerance (±1% vs ±5%) and increased power rating (2W vs 1W) with automotive AEC-Q200 qualification and extended operating temperature (-55°C ~ 155°C).

Direct Equivalents (Matched Specifications): 4-1622824-3 and RL73H3AR62FTDF maintain the 1W power rating and current sense feature with improved tolerance (±1%) and extended operating temperature range (-55°C ~ 155°C).

Alternative Category (Tolerance Match): RHC2512JTR620 matches the original ±5% tolerance with increased power rating (2W) and extended operating temperature range.

Engineering Selection Recommendations

Primary Selection: RCWE2512R620FKEA (Vishay Dale) is the recommended upgrade path. This part maintains full functional compatibility while providing superior tolerance (±1%), increased power headroom (2W), automotive AEC-Q200 qualification, and extended operating temperature range. ROHS3 compliance is maintained.

Secondary Selection: 4-1622824-3 (TE Connectivity) or RL73H3AR62FTDF (TE Connectivity) are suitable direct equivalents for applications requiring matched 1W power rating. Both offer improved tolerance and extended temperature range. Note that RL73H3AR62FTDF is RoHS non-compliant and should be evaluated against regulatory requirements.

Alternative Selection: RHC2512JTR620 (Stackpole Electronics) provides tolerance matching with the original part while offering increased power rating and extended operating temperature. ROHS3 compliance and REACH compliance are confirmed.

All substitute parts maintain the 2512 package footprint, thick film composition, current sense functionality, and moisture resistance required for direct board-level replacement.

Frequently Asked Questions (FAQ)

Q: Can RCWE2512R620FKEA replace LVC25JR620EV directly on the PCB? A: Yes. Both parts use the 2512 (6432 Metric) package with identical footprint dimensions. The RCWE2512R620FKEA is a direct mechanical and electrical substitute with enhanced specifications.

Q: What is the difference between the 1W and 2W rated parts? A: Power rating indicates maximum continuous power dissipation. The 2W parts (RCWE2512R620FKEA and RHC2512JTR620) provide additional thermal margin in high-current applications. The 1W parts (4-1622824-3 and RL73H3AR62FTDF) match the original specification.

Q: Why is RL73H3AR62FTDF marked as RoHS non-compliant? A: This part does not meet ROHS3 requirements. Selection should be based on end-product regulatory compliance obligations. RCWE2512R620FKEA, 4-1622824-3, and RHC2512JTR620 are all ROHS3 compliant alternatives.

Q: Does tolerance affect circuit performance? A: Tolerance determines resistance value accuracy. The ±1% parts (RCWE2512R620FKEA, 4-1622824-3, RL73H3AR62FTDF) provide tighter control than the original ±5% specification, beneficial for precision current sensing applications.

Q: Are all substitutes automotive qualified? A: Only RCWE2512R620FKEA carries AEC-Q200 automotive qualification. Other parts are suitable for industrial and commercial applications. Automotive applications require AEC-Q200 certification.

Q: What is the operating temperature consideration? A: The original part operates -40°C ~ 125°C. All active substitutes extend this to -55°C ~ 155°C, providing broader environmental compatibility without performance degradation.
