Key Parameters

Substitute Part Grouping Explanation

Substitution of the LVC25FR470EV is based on strict equivalence across the following critical parameters:

• Electrical Specifications: Resistance value (470 mOhms), tolerance (±1%), power rating (1W), and temperature coefficient (±100ppm/°C) must be identical
• Package Compatibility: 2512 (6432 Metric) package ensures mechanical fit and thermal performance equivalence
• Composition and Application: Thick film construction with current sense capability maintains functional performance
• Environmental Compliance: RoHS3 compliance and MSL 1 rating ensure regulatory and reliability equivalence
• Operating Temperature: Substitute parts must support the required thermal operating window

The TE Connectivity RL73H3AR47FTE and RL73H3AR47FTDF meet all substitution criteria as active components with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity RL73H3 series parts (RL73H3AR47FTE and RL73H3AR47FTDF) provide direct functional equivalence to the obsolete LVC25FR470EV. Selection between the two TE Connectivity options is determined by packaging requirements: RL73H3AR47FTE is supplied in Tape & Reel (TR) packaging, while RL73H3AR47FTDF is also supplied in Tape & Reel (TR) packaging. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in current manufacturing environments. The extended operating temperature range (-55°C ~ 155°C) of the TE Connectivity substitutes provides enhanced thermal margin beyond the original part specification.

Frequently Asked Questions (FAQ)

Q: Can RL73H3AR47FTE and RL73H3AR47FTDF be used interchangeably with LVC25FR470EV?

A: Both TE Connectivity parts meet all electrical and mechanical substitution criteria. Identical resistance (470 mOhms), tolerance (±1%), power rating (1W), package (2512), and composition (thick film) ensure direct compatibility. Both are active products with current availability.

Q: What are the dimensional differences between the original and substitute parts?

A: The LVC25FR470EV measures 0.250" L x 0.130" W with 0.026" maximum seated height. The RL73H3 series measures 0.250" L x 0.122" W with 0.028" maximum seated height. These minor dimensional variations remain within 2512 package tolerance and do not affect board-level fit or thermal performance.

Q: Are there temperature range considerations for substitution?

A: The original LVC25FR470EV operates from -40°C to 125°C. The RL73H3 substitutes operate from -55°C to 155°C, providing extended thermal capability. Applications requiring the original temperature range are fully supported by the substitute parts.

Q: What packaging formats are available for the substitute parts?

A: Both RL73H3AR47FTE and RL73H3AR47FTDF are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Are the substitute parts RoHS compliant?

A: Both RL73H3 series parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original LVC25FR470EV.
