Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

• Resistance value: 680 mOhms
• Tolerance: ±1%
• Package / Case: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are grouped into two categories based on power rating compatibility:

Direct Equivalents (1W Rating): Parts maintaining the original 1W power specification with identical electrical characteristics.

Upgraded Alternatives (2W Rating): Parts with increased power dissipation capability while maintaining all other electrical parameters, suitable for applications requiring higher thermal margin.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (1W Specification Required):

RL73H3AR68FTE and RL73H3AR68FTDF from TE Connectivity Passive Product are active direct equivalents. Both maintain 1W power rating with identical electrical parameters. RL73H3AR68FTDF is manufacturer recommended. Both parts feature extended operating temperature range (-55°C ~ 155°C) compared to the original specification, providing improved thermal margin. Current sense capability is retained.

For Upgraded Applications (2W Specification Acceptable):

RCWE2512R680FKEA (Vishay Dale) and RHC2512FTR680 (Stackpole Electronics) provide 2W power rating while maintaining all other electrical specifications. RCWE2512R680FKEA includes AEC-Q200 automotive qualification. RHC2512FTR680 is manufacturer recommended. Both support extended operating temperature range (-55°C ~ 155°C). These options are suitable when circuit design permits higher power dissipation capability.

All substitute parts are ROHS3 compliant with MSL 1 rating, matching the original part's environmental compliance profile.

Frequently Asked Questions (FAQ)

Q: Can RL73H3AR68FTE and RL73H3AR68FTDF be used interchangeably with LVC25FR680EV?

A: Yes. Both TE Connectivity parts maintain identical resistance (680 mOhms), tolerance (±1%), power rating (1W), package (2512), composition (thick film), and temperature coefficient (±100ppm/°C). Both are active products with ROHS3 compliance and MSL 1 rating. RL73H3AR68FTDF is manufacturer recommended.

Q: What is the difference between 1W and 2W rated substitutes?

A: Power rating indicates maximum continuous power dissipation capability. 1W substitutes (RL73H3AR68FTE, RL73H3AR68FTDF) match the original specification. 2W substitutes (RCWE2512R680FKEA, RHC2512FTR680) provide increased thermal margin. Selection depends on circuit current requirements and thermal design. All maintain identical electrical characteristics at rated power.

Q: Are all substitute parts in the same 2512 package?

A: Yes. All substitute parts use 2512 (6432 Metric) package with two terminations. Physical dimensions vary slightly within tolerance (length 0.248" to 0.250", width 0.122" to 0.130", height 0.026" to 0.028"), but all are compatible with standard 2512 footprints.

Q: Do substitute parts support current sense applications?

A: RL73H3AR68FTE and RL73H3AR68FTDF explicitly feature current sense capability. RCWE2512R680FKEA includes current sense with automotive AEC-Q200 qualification. RHC2512FTR680 does not list current sense as a feature but maintains electrical compatibility for current sensing applications.

Q: What is the operating temperature difference between the original and substitutes?

A: LVC25FR680EV operates -40°C ~ 125°C. All substitute parts operate -55°C ~ 155°C, providing extended temperature range. This represents improved performance margin for both low and high temperature environments.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original part's environmental compliance requirements.
