P0422 Common Mode Choke 4.7A Surface Mount - Equivalent & Substitute Parts

Part Overview

The P0422 is a 2-line common mode choke (CMC) designed for power line filtering applications. It features a 4.7A maximum current rating with 40mOhm DC resistance, housed in a surface mount package with horizontal 4-pad configuration. The component is actively produced, RoHS3 compliant, and maintains unlimited moisture sensitivity rating (MSL 1). This part is used in power distribution and EMI suppression circuits where dual-line filtering is required. Substitute parts are identified based on matching electrical specifications and mechanical compatibility within the same product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P0422 is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Current rating (4.7A), DC resistance (40mOhm maximum), and filter type (power line, 2-line configuration)
• Mechanical Compatibility: Surface mount mounting type, identical package footprint (Horizontal, 4 PC Pad), and matching physical dimensions (19.56mm x 17.02mm x 9.91mm maximum height)
• Environmental & Compliance: Operating temperature range (-40°C to 120°C), RoHS3 compliance, and MSL rating (1)
• Packaging Format: The primary distinction between P0422 and its substitute relates to packaging delivery method (tape/reel versus tube), which does not affect electrical or mechanical performance

The P0422NL variant meets all substitution criteria as a direct equivalent, differing only in packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

Both P0422 and P0422NL are active production components from Pulse Electronics with full RoHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on procurement and assembly requirements:

• P0422: Standard packaging format suitable for automated pick-and-place assembly workflows
• P0422NL: Tube packaging format, applicable for manual assembly operations or specific supply chain requirements

Both parts maintain the same performance envelope across current handling (4.7A), impedance characteristics (40mOhm DCR), thermal operating range (-40°C to 120°C), and physical footprint. Inventory availability may influence selection; P0422NL currently shows higher stock levels (1200 pcs vs. 775 pcs).

Frequently Asked Questions (FAQ)

Q: Can P0422NL be used as a direct replacement for P0422 in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (tube versus standard). PCB layout, thermal performance, and electrical behavior remain unchanged.

Q: Does packaging format affect assembly compatibility?

A: Packaging format affects supply chain handling and assembly line equipment compatibility. Standard packaging (P0422) integrates with tape-and-reel automated systems. Tube packaging (P0422NL) requires manual placement or alternative feeder systems. Electrical and mechanical performance on the PCB is unaffected.

Q: Are there any compliance or certification differences between P0422 and P0422NL?

A: No. Both parts carry identical RoHS3 compliance, MSL 1 rating, and environmental certifications. Regulatory status is equivalent.

Q: What determines if a part can substitute for the P0422?

A: Substitution requires matching specifications across: current rating (4.7A), DC resistance (40mOhm maximum), filter type (power line, 2-line), mounting type (surface mount), package footprint (Horizontal, 4 PC Pad), physical dimensions (19.56mm x 17.02mm x 9.91mm), operating temperature range (-40°C to 120°C), and compliance certifications (RoHS3, MSL 1).

Q: Can parts from other manufacturers substitute for the P0422?

A: Substitution eligibility is restricted to parts meeting all specified electrical and mechanical parameters. Only Pulse Electronics P0422NL is listed as an equivalent variant based on provided data.
