Substitute Part Grouping Explanation

Substitution for the LVC25JR680EV is determined by the following critical parameters:

Resistance Value: 680 mOhms (exact match required)
Package / Case: 2512 (6432 Metric) (physical and electrical compatibility)
Tolerance: ±5% or better (±1% is acceptable as upgrade)
Power Rating: 1W minimum (2W is acceptable as upgrade)
Composition: Thick Film (maintains electrical characteristics)
Temperature Coefficient: ±100ppm/°C (standard for this category)
RoHS Compliance: ROHS3 Compliant (regulatory requirement)

All substitute parts listed maintain these core parameters while offering active product status and improved availability.

Engineering Selection Recommendations

Direct Tolerance Match (±5%):

CRM2512-JX-R680ELF (Bourns Inc.) and RHC2512JTR680 (Stackpole Electronics Inc) maintain the original ±5% tolerance specification while offering 2W power rating and extended operating temperature range (-55°C ~ 155°C). Both parts are active products with ROHS3 compliance.

Upgraded Tolerance (±1%):

RL73H3AR68FTE and RL73H3AR68FTDF (TE Connectivity Passive Product) provide ±1% tolerance with 1W power rating, matching the original power specification. Both are active products with extended temperature range and ROHS3 compliance.
RCWE2512R680FKEA (Vishay Dale) offers ±1% tolerance with 2W power rating and AEC-Q200 automotive qualification. Active product status with ROHS3 compliance.
RHC2512FTR680 (Stackpole Electronics Inc) provides ±1% tolerance with 2W power rating, active product status, and ROHS3 compliance.

All substitute parts are active products with ROHS3 compliance, ensuring regulatory alignment and long-term availability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can I use a 2W rated substitute in place of the 1W original? A: Yes. A higher power rating is a conservative substitution that maintains circuit safety margins. The 2512 package dimensions remain identical across all listed parts.

Q: What is the difference between ±5% and ±1% tolerance substitutes? A: Tolerance defines the acceptable resistance variation from the nominal 680 mOhm value. ±1% tolerance provides tighter control (±6.8 mOhms) compared to ±5% (±34 mOhms). Selection depends on circuit accuracy requirements.

Q: Are all substitute parts pin-compatible with the original LVC25JR680EV? A: Yes. All substitute parts use the 2512 (6432 Metric) package with 2 terminations, maintaining identical PCB footprint and electrical connection points.

Q: Why do some substitutes have extended operating temperature ranges? A: Substitute parts from active product lines (Vishay Dale, TE Connectivity, Bourns Inc., Stackpole Electronics Inc) are manufactured to current specifications, which typically include wider temperature ranges (-55°C ~ 155°C) compared to the obsolete original part (-40°C ~ 125°C).

Q: Is AEC-Q200 qualification required for my application? A: AEC-Q200 qualification is specific to automotive applications. RCWE2512R680FKEA includes this certification. For non-automotive applications, other active substitutes without automotive qualification are suitable.

Q: What is the significance of the 2512 package designation? A: 2512 is the imperial designation (0.250" L x 0.130" W). The metric equivalent is 6432 (6.35mm x 3.30mm). All listed parts use this standardized package, ensuring mechanical and electrical compatibility.
