Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LVC25FR750EV is determined by the following mandatory parameters:

• Resistance value: 750 mOhms
• Tolerance: ±1%
• Package / Case: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

The substitute parts identified maintain these core electrical and mechanical specifications. Variations in power rating (1W vs. 2W), operating temperature range, and product status (active vs. obsolete) are noted but do not preclude substitution when the mandatory parameters align. Physical dimensions remain within acceptable tolerances for PCB footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain electrical equivalence to the LVC25FR750EV based on resistance, tolerance, package, and composition specifications.

RCWE2512R750FKEA (Vishay Dale) provides a 2W power rating upgrade with automotive AEC-Q200 qualification. This part is suitable for applications requiring enhanced thermal performance or automotive-grade reliability. The extended operating temperature range (-55°C ~ 155°C) accommodates wider environmental conditions.

RL73H3AR75FTDF and RL73H3AR75FTE (TE Connectivity Passive Product) maintain the original 1W power specification with extended operating temperature range (-55°C ~ 155°C). Both parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating. RL73H3AR75FTE offers significantly higher inventory availability (39195 Pcs) compared to RL73H3AR75FTDF (5965 Pcs), providing supply chain advantages for high-volume applications.

All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification, matching the original part's environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can RCWE2512R750FKEA replace LVC25FR750EV in any application?

A: RCWE2512R750FKEA is electrically equivalent with identical resistance, tolerance, package, and composition. The 2W power rating is a superset of the 1W requirement, making it suitable for direct substitution. The automotive AEC-Q200 qualification adds reliability assurance for demanding applications.

Q: What is the difference between RL73H3AR75FTDF and RL73H3AR75FTE?

A: Both parts are electrically and mechanically identical. The primary difference is inventory availability: RL73H3AR75FTE has 39195 Pcs in stock versus 5965 Pcs for RL73H3AR75FTDF. Both are active products from TE Connectivity Passive Product series RL73 / CGS.

Q: Are the physical dimensions compatible with the original LVC25FR750EV footprint?

A: Yes. All substitute parts use the 2512 (6432 Metric) package. Dimensional variations are within acceptable tolerances: length ranges from 0.248" to 0.250" (6.30mm to 6.35mm), width ranges from 0.122" to 0.130" (3.10mm to 3.30mm), and height ranges from 0.026" to 0.028" (0.65mm to 0.70mm). These tolerances are standard for 2512 package specifications and do not affect PCB assembly compatibility.

Q: Does the extended operating temperature range of substitute parts affect compatibility?

A: No. The substitute parts' extended operating temperature ranges (-55°C ~ 155°C) are supersets of the original part's range (-40°C ~ 125°C). This provides enhanced performance margin without affecting electrical characteristics within the original operating window.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts carry ROHS3 compliance certification, matching the original LVC25FR750EV specification.
