P0751.102NL Equivalent & Substitute Parts

Part Overview

The P0751.102NL is a 1 µH unshielded wirewound inductor manufactured by Pulse Electronics, rated for 6.8 A continuous current with a maximum DC resistance of 10 mOhm. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified based on matching inductance value, shielding type, mounting configuration, and operating temperature range compatibility to ensure functional equivalence in surface mount applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P0751.102NL are qualified based on the following criteria:

• Inductance value of 1 µH (±20% tolerance)
• Unshielded configuration
• Surface mount package type
• Current rating equal to or greater than 6.8 A
• DC resistance of 10 mOhm or lower
• Operating temperature range that encompasses or exceeds -40°C to 130°C
• ROHS3 compliance and REACH unaffected status

Three substitute parts meet these electrical and mechanical parameters: 7445601 (Würth Elektronik), SDR1005-1R0ML (Bourns Inc.), and UP2B-1R0-R (Eaton - Electronics Division).

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are Active product status and maintain ROHS3 compliance with REACH unaffected designation, matching the regulatory requirements of the P0751.102NL.

The 7445601 (Würth Elektronik WE-PD4 series) provides higher current rating (8.6 A) and lower DC resistance (7 mOhm), with operating temperature range of -40°C to 125°C. This part is suitable for applications where the upper temperature limit of 125°C is acceptable.

The SDR1005-1R0ML (Bourns SDR1005 series) offers 7.5 A current rating and 7 mOhm DC resistance, with operating temperature range of -40°C to 125°C. This part is suitable for applications where the upper temperature limit of 125°C is acceptable.

The UP2B-1R0-R (Eaton UNI-PAC series) provides the highest current rating (9.3 A) and lowest DC resistance (6.5 mOhm). However, the operating temperature range is limited to -40°C to 85°C, restricting use in applications requiring operation above 85°C.

Selection should prioritize operating temperature range requirements. For applications requiring operation up to 130°C, the P0751.102NL remains the only qualified option. For applications with maximum operating temperature of 125°C or lower, the Würth or Bourns substitutes are suitable. For applications with maximum operating temperature of 85°C or lower, the Eaton substitute offers superior current handling and lower resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 7445601 replace the P0751.102NL in all applications?

A: The 7445601 is electrically compatible for applications with operating temperatures up to 125°C. Applications requiring operation above 125°C must use the P0751.102NL, as the substitute part is rated only to 125°C maximum.

Q: What is the primary difference between the substitute parts?

A: The three substitutes differ in current rating, DC resistance, and maximum operating temperature. The Würth 7445601 and Bourns SDR1005-1R0ML both support 125°C maximum temperature. The Eaton UP2B-1R0-R supports only 85°C maximum temperature but offers superior current handling and lower resistance.

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

A: All parts are surface mount with nonstandard package dimensions. Physical dimensions vary slightly: P0751.102NL is 12.95mm × 9.40mm × 5.46mm; 7445601 is 12.70mm × 10.00mm × 5.30mm; SDR1005-1R0ML is 12.70mm × 10.00mm × 5.00mm; UP2B-1R0-R is 13.97mm × 10.41mm × 6.00mm. PCB layout verification is required for dimensional compatibility.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the P0751.102NL.

Q: Which substitute offers the best performance characteristics?

A: The Eaton UP2B-1R0-R provides the lowest DC resistance (6.5 mOhm) and highest current rating (9.3 A). However, this advantage is limited to applications with maximum operating temperature of 85°C or lower.
