Key Parameters

Substitute Part Grouping Explanation

Substitution for the LVC25FR250EV is determined by strict equivalence in the following parameters:

• Resistance value: 250 mOhms
• Tolerance: ±1%
• Package / Case: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts maintain these core electrical and mechanical specifications. While substitute parts feature higher power ratings (2W versus 1W) and extended operating temperature ranges (-55°C ~ 155°C versus -40°C ~ 125°C), these represent improvements in performance envelope and do not compromise compatibility in applications designed for the original LVC25FR250EV specifications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing support, addressing the obsolescence status of the LVC25FR250EV. Selection between CRM2512-FX-R250ELF and RHC2512FTR250 should be based on application-specific requirements and procurement availability.

CRM2512-FX-R250ELF is supplied in Tape & Reel packaging with current sense feature designation and maintains REACH Unaffected status. RHC2512FTR250 is supplied in Tape & Reel packaging with moisture resistant feature designation and maintains REACH Unaffected status. Both parts are ROHS3 compliant with MSL 1 rating.

The higher power ratings (2W) and extended operating temperature ranges of both substitutes provide design margin beyond the original 1W, 1% tolerance specification. Dimensional variations within the 2512 package footprint are within acceptable PCB assembly tolerances.

Frequently Asked Questions (FAQ)

Q: Can CRM2512-FX-R250ELF or RHC2512FTR250 be used as direct replacements for LVC25FR250EV?

A: Yes. Both parts maintain identical resistance (250 mOhms), tolerance (±1%), package (2512), composition (thick film), and temperature coefficient (±100ppm/°C). The higher power ratings and extended temperature ranges represent performance improvements compatible with LVC25FR250EV applications.

Q: What is the difference between the two substitute parts?

A: CRM2512-FX-R250ELF emphasizes current sense functionality. RHC2512FTR250 emphasizes moisture resistant characteristics. Both are electrically and mechanically equivalent for the specified parameters. Selection may depend on feature prioritization and supplier availability.

Q: Are there packaging differences between the main part and substitutes?

A: The main part LVC25FR250EV packaging type is not specified in available data. Both substitutes are supplied in Tape & Reel (TR) format. Dimensional variations exist within the 2512 package specification: LVC25FR250EV measures 0.250" L x 0.130" W (6.35mm x 3.30mm); CRM2512-FX-R250ELF measures 0.248" L x 0.122" W (6.30mm x 3.10mm); RHC2512FTR250 measures 0.248" L x 0.126" W (6.30mm x 3.20mm). These variations are within standard 2512 package tolerances.

Q: Do the substitute parts maintain RoHS and MSL compliance?

A: Yes. Both CRM2512-FX-R250ELF and RHC2512FTR250 are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original LVC25FR250EV specifications.
