Substitute Part Grouping Explanation

Substitute parts for the ETQ-P3WR82WFN are qualified based on the following electrical and mechanical parameters:

Inductance Value: All substitutes maintain 820 nH ±20% tolerance
Current Rating: Substitutes rated at 13 A or higher meet or exceed the 14 A requirement
DC Resistance: All substitutes specified at 8 mOhm maximum or lower
Shielding: All substitutes are shielded inductors
Mounting: All substitutes are surface mount components
Physical Compatibility: All substitutes fit within the 7.00mm x 6.60mm x 3.00mm envelope or smaller equivalent footprints
Test Frequency: All substitutes characterized at 100 kHz

The following active substitute parts meet these criteria and are available as direct replacements.

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing status, providing supply continuity for the obsolete ETQ-P3WR82WFN. Selection among substitutes should be based on the following factors:

For applications requiring lowest DC resistance: The 0630CDMCCDS-R82MC (Sumida) offers 6 mOhm maximum, providing improved efficiency compared to the 8 mOhm specification of the original part.

For applications requiring highest current saturation margin: The HCMA0703-R82-R (Eaton) and PG0426.821NL (Pulse Electronics) both specify 24 A saturation current, providing maximum headroom above the 14 A rating.

For extended temperature operation: The LMLP07A7MR82DTAS (KYOCERA AVX) supports operation to 155°C, exceeding the standard -55°C to 125°C range of most alternatives.

For automotive applications: The HCMA0703-R82-R (Eaton) carries AEC-Q200 qualification. The SRP7028A-R82M (Bourns) also carries AEC-Q200 qualification and provides Q factor specification (15 @ 100kHz) and self-resonant frequency data (61 MHz).

All substitute parts are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can any of these substitutes be used as a direct replacement for the ETQ-P3WR82WFN?

A: Yes. All listed parts maintain the same 820 nH inductance value, ±20% tolerance, and 8 mOhm or lower DC resistance. Physical dimensions are compatible with the original 7.00mm x 6.60mm x 3.00mm footprint. Electrical performance at 100 kHz test frequency is equivalent.

Q: What is the difference between the core materials used in these substitutes?

A: The original ETQ-P3WR82WFN uses metal composite core construction. Substitutes employ metal, carbonyl powder, or iron powder cores. These material differences affect saturation current characteristics and temperature stability but do not impact the specified inductance, current rating, or DC resistance parameters at rated operating conditions.

Q: Are all substitutes suitable for high-temperature applications?

A: Most substitutes operate across -55°C to 125°C. The LMLP07A7MR82DTAS extends to 155°C maximum. The PG0426.821NL operates to 130°C. Verify the operating temperature range of your specific application before selection.

Q: Do any substitutes provide additional technical specifications beyond the original part?

A: Yes. The SRP7028A-R82M (Bourns) provides Q factor (15 @ 100kHz) and self-resonant frequency (61 MHz) data. The 0630CDMCCDS-R82MC (Sumida) specifies saturation current at 19.5 A. These additional parameters may be useful for detailed circuit analysis but are not required for basic substitution compatibility.

Q: Which substitute offers the best value for cost-sensitive applications?

A: This determination requires current pricing and availability data not provided in this reference. Consult your component supplier for cost and lead time comparisons among active parts.

Q: Are there any compliance or certification differences between substitutes?

A: The HCMA0703-R82-R (Eaton) and SRP7028A-R82M (Bourns) carry AEC-Q200 automotive qualification. All substitutes are RoHS3 compliant. The SRP7028A-R82M and ASPI-0630LR-R82M-T15 carry REACH Unaffected status. Select based on your application's compliance requirements.
