Key Parameters

Substitute Part Grouping Explanation

Substitution for the LVC25JR470EV is determined by the following critical parameters: resistance value (470 mOhms), package type (2512), composition (thick film), temperature coefficient (±100ppm/°C), and RoHS3 compliance. Tolerance and power rating variations are permitted within the substitute group based on application requirements and active product availability.

The substitute parts are grouped into two categories:

Category 1: Direct Electrical Equivalents (±1% Tolerance, 1W Power)

• RL73H3AR47FTE (TE Connectivity)
• RL73H3AR47FTDF (TE Connectivity)

These parts maintain the 1W power rating with improved tolerance (±1%) and extended operating temperature range (-55°C ~ 155°C).

Category 2: Upgraded Power Rating Equivalents (±5% Tolerance, 2W Power)

• CRM2512-JX-R470ELF (Bourns Inc.)
• RHC2512JTR470 (Stackpole Electronics Inc.)

These parts provide increased power dissipation capability (2W) while maintaining the original ±5% tolerance and extended operating temperature range (-55°C ~ 155°C).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are active products with ROHS3 compliance and MSL Level 1 rating, ensuring regulatory compliance and long-term availability.

For applications requiring tolerance matching with the original LVC25JR470EV (±5%), select CRM2512-JX-R470ELF or RHC2512JTR470. These parts provide identical tolerance specifications with increased power dissipation (2W) and extended operating temperature range.

For applications where improved tolerance (±1%) is acceptable or beneficial, RL73H3AR47FTE or RL73H3AR47FTDF provide tighter resistance control while maintaining the 1W power rating and extended temperature range.

All substitute parts maintain the 2512 package footprint, thick film composition, and ±100ppm/°C temperature coefficient, ensuring mechanical and thermal compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can RL73H3AR47FTE and RL73H3AR47FTDF be used interchangeably with the LVC25JR470EV?

A: Yes. Both parts share identical electrical specifications (470 mOhms, ±1% tolerance, 1W power, ±100ppm/°C temperature coefficient) and package type (2512). The ±1% tolerance is tighter than the original ±5%, making these parts suitable for applications where the original tolerance is acceptable. The extended operating temperature range (-55°C ~ 155°C) provides additional margin compared to the original specification (-40°C ~ 125°C).

Q: What is the difference between the TE Connectivity parts (RL73H3AR47FTE and RL73H3AR47FTDF)?

A: Both TE Connectivity parts are electrically identical with the same resistance, tolerance, power rating, and temperature specifications. The primary difference is packaging: RL73H3AR47FTE is supplied in Tape & Reel format, while RL73H3AR47FTDF is also supplied in Tape & Reel format. Consult the respective datasheets for specific packaging and reel configuration details.

Q: Should I select the 2W power rated parts (CRM2512-JX-R470ELF or RHC2512JTR470) over the 1W parts?

A: Selection depends on thermal design requirements. The 2W parts provide increased power dissipation capability and are suitable for applications with higher current or thermal stress. If the original 1W design is adequate, the 1W substitute parts are appropriate. The 2W parts maintain the same package footprint and are mechanically compatible.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with MSL Level 1 rating, meeting regulatory requirements for lead-free and hazardous substance restrictions.

Q: What is the impact of tolerance differences on circuit performance?

A: The original LVC25JR470EV specifies ±5% tolerance. The TE Connectivity substitutes (RL73H3AR47FTE and RL73H3AR47FTDF) provide ±1% tolerance, which represents tighter resistance control. For current sense applications, improved tolerance may reduce measurement error. The Bourns and Stackpole substitutes maintain ±5% tolerance, matching the original specification.
