LVC25FR050EV Equivalent & Substitute Parts

Part Overview

The LVC25FR050EV is a 50 mOhms ±1% 1W chip resistor in 2512 (6432 Metric) package manufactured by Ohmite. This current sense thick film resistor is designed for applications requiring precision low-resistance measurements with moisture resistance. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LVC25FR050EV is determined by the following critical parameters:

• Resistance Value: 50 mOhms ±1% (exact match required)
• Package Type: 2512 (6432 Metric) (physical and electrical compatibility)
• Tolerance: ±1% (precision requirement)
• Composition: Thick Film (material consistency)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity: MSL 1 (Unlimited) (environmental robustness)

The substitute parts identified maintain these core parameters while offering improvements in power rating, temperature coefficient, and operating temperature range. All substitutes are active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

CSR2512FG50L0 (Stackpole Electronics Inc) is suitable for direct substitution in applications where the increased power rating (2W vs 1W) and extended operating temperature range (-55°C to 155°C) provide design margin. This part is active and ROHS3 compliant with standard industrial packaging (Tape & Reel).

CSRN2512FK50L0 (Stackpole Electronics Inc) is recommended for automotive and mission-critical applications requiring AEC-Q200 qualification. This part offers the same electrical specifications as CSR2512FG50L0 with automotive-grade reliability certification. Availability is significantly higher (206,307 pcs in stock). Cut Tape & Digi-Reel packaging is available.

CRM2512-FX-R050ELF (Bourns Inc.) is the manufacturer-recommended substitute. It maintains the original ±100 ppm/°C temperature coefficient while providing 2W power rating and extended temperature range. This part is active and ROHS3 compliant with Tape & Reel packaging.

All three substitutes maintain the critical 50 mOhms ±1% resistance specification, 2512 package footprint, and MSL 1 moisture sensitivity rating required for functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can CSR2512FG50L0 be used as a direct replacement for LVC25FR050EV?

A: Yes. Both parts share identical resistance (50 mOhms ±1%), tolerance (±1%), package (2512), composition (thick film), and moisture sensitivity (MSL 1). The substitute offers higher power rating (2W vs 1W) and wider operating temperature range (-55°C to 155°C vs -40°C to 125°C), making it functionally compatible for the same circuit applications.

Q: What is the difference between CSR2512FG50L0 and CSRN2512FK50L0?

A: Both parts have identical electrical specifications (50 mOhms ±1%, 2W, ±200 ppm/°C). The primary difference is that CSRN2512FK50L0 carries AEC-Q200 automotive qualification and is available in Cut Tape & Digi-Reel packaging, while CSR2512FG50L0 is standard industrial grade in Tape & Reel packaging. CSRN2512FK50L0 has significantly higher inventory availability.

Q: Why does CRM2512-FX-R050ELF have ±100 ppm/°C while other substitutes have ±200 ppm/°C?

A: CRM2512-FX-R050ELF maintains the original temperature coefficient specification (±100 ppm/°C) from the LVC25FR050EV, providing tighter temperature stability. CSR2512FG50L0 and CSRN2512FK50L0 specify ±200 ppm/°C, which is acceptable for most current sense applications but represents a relaxed specification.

Q: Are all substitutes RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental compliance profile.

Q: What packaging options are available for these substitutes?

A: CSR2512FG50L0 and CRM2512-FX-R050ELF are supplied in Tape & Reel (TR) packaging. CSRN2512FK50L0 is available in Cut Tape (CT) & Digi-Reel packaging, offering flexibility for both automated assembly and manual component handling.
