Key Parameters

Substitute Part Grouping Explanation

The P0429 has one direct substitute: P0429NL. Both parts are manufactured by Pulse Electronics and share identical electrical and mechanical specifications. The substitution is valid based on the following critical parameters:

• Current Rating: 9.7A (identical)
• DC Resistance: 14mOhm maximum (identical)
• Number of Lines: 2 (identical)
• Operating Temperature: -40°C to 120°C (identical)
• Physical Dimensions: 30.99mm × 25.40mm × 12.70mm (identical)
• Package / Case: Horizontal, 4 PC Pad (identical)
• RoHS and REACH Compliance: Identical

The only difference between these parts is packaging format: P0429 uses standard packaging while P0429NL uses tube packaging. This distinction affects only procurement and assembly logistics, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both P0429 and P0429NL are active production parts from Pulse Electronics with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability:

• P0429 is suitable for standard procurement workflows with 798 units in stock.
• P0429NL is suitable for applications requiring tube packaging, with higher inventory availability at 1338 units.

Both parts meet ROHS3 compliance and REACH requirements. Moisture sensitivity level 1 indicates unlimited shelf life under standard storage conditions. Either part is electrically and mechanically interchangeable in circuit designs requiring a 2-line common mode choke with 9.7A current handling and 14mOhm DC resistance.

Frequently Asked Questions (FAQ)

Q: Can P0429NL be used as a direct replacement for P0429?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (tube vs. standard). Circuit performance and PCB assembly compatibility are unchanged.

Q: What determines compatibility between P0429 and P0429NL?

A: Compatibility is determined by matching electrical parameters (current rating, DC resistance, number of lines), mechanical dimensions, and mounting type. Both parts meet these criteria identically.

Q: Does packaging format affect component performance?

A: No. Packaging format (standard vs. tube) affects only procurement, storage, and assembly handling. Electrical and mechanical performance are identical.

Q: Are both parts actively manufactured?

A: Yes. Both P0429 and P0429NL are active production parts from Pulse Electronics.

Q: What is the significance of the MSL 1 rating?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life under standard storage conditions. No special moisture control measures are required during storage or handling.

Q: Do both parts meet environmental compliance standards?

A: Yes. Both P0429 and P0429NL are ROHS3 compliant and REACH unaffected.
