P0752.684NL Equivalent & Substitute Parts

Part Overview

The P0752.684NL is a 680 µH unshielded wirewound surface mount inductor manufactured by Pulse Electronics. Rated for 400 mA with a maximum DC resistance of 2.17Ohm, this component is designed for applications requiring fixed inductance in compact form factors. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts may be required due to inventory constraints, lead time considerations, or application-specific performance requirements while maintaining equivalent electrical and mechanical functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P0752.684NL are qualified based on the following critical parameters:

• Inductance Value: Exact match at 680 µH
• Inductance Tolerance: Acceptable range ±10% to ±20%
• Current Rating: Equal to or greater than 400 mA
• DC Resistance: Maximum 2.6Ohm (within acceptable operating margin)
• Shielding Configuration: Unshielded
• Mounting Type: Surface Mount
• Operating Temperature Range: Minimum -40°C ~ 125°C
• Compliance: ROHS3 Compliant, MSL 1

All substitute parts maintain the same inductance value and unshielded configuration. Variations in current saturation rating, core material, and package dimensions are permitted within the specified electrical operating envelope.

Engineering Selection Recommendations

74456268 (Würth Elektronik WE-PD4 Series)

This substitute provides higher current rating (500 mA) and saturation current (550 mA) compared to the primary part. The tighter inductance tolerance (±10%) and ferrite drum core construction offer improved performance stability. Operating temperature range extends to -40°C ~ 125°C. This part is suitable for applications where the P0752.684NL current rating is marginal or where improved tolerance is required.

SDR1005-681KL (Bourns Inc. SDR1005 Series)

This substitute features tighter inductance tolerance (±10%) and ferrite drum core construction. Current rating is 350 mA, which is below the primary part specification. This part is suitable only for applications where the required current does not exceed 350 mA. The SDR1005 series offers higher self-resonant frequency (3 MHz) and documented Q factor (72 @ 96kHz). All parts maintain ROHS3 compliance and MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can the 74456268 directly replace the P0752.684NL?

A: Yes. The 74456268 maintains the same 680 µH inductance value, unshielded configuration, and surface mount package. The higher current rating (500 mA vs. 400 mA) and lower DC resistance tolerance (±10% vs. ±20%) make it electrically compatible for applications operating at or below 400 mA.

Q: Can the SDR1005-681KL directly replace the P0752.684NL?

A: The SDR1005-681KL is compatible only for applications where the operating current does not exceed 350 mA. The part maintains 680 µH inductance and unshielded configuration but has a lower current rating than the primary part.

Q: What is the impact of DC resistance variation between parts?

A: The P0752.684NL specifies 2.17Ohm maximum DC resistance, while both substitutes specify 2.6Ohm maximum. This 0.43Ohm increase results in higher resistive losses. For applications sensitive to power dissipation or thermal performance, verify that the substitute's DC resistance is acceptable for your circuit design.

Q: Are there package dimension differences between these parts?

A: The P0752.684NL measures 0.510" L x 0.370" W x 0.215" H (12.95mm x 9.40mm x 5.46mm). The 74456268 measures 0.500" L x 0.394" W x 0.209" H (12.70mm x 10.00mm x 5.30mm). The SDR1005-681KL measures 0.500" L x 0.394" W x 0.197" H (12.70mm x 10.00mm x 5.00mm). Verify PCB layout compatibility before substitution.

Q: Do all parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. All are classified under ECCN EAR99.
