P0422T Common Mode Choke Equivalent & Substitute Parts

Part Overview

The P0422T is a 2-line common mode choke (CMC) designed for power line filtering applications in surface mount configurations. This component features a 4.7A current rating with 40mOhm maximum DC resistance and operates across the temperature range of -40°C to 120°C. The P0422T is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement planning.

Substitute Part Grouping Explanation

Substitution of the P0422T is determined by strict equivalence across the following critical parameters:

• Filter Type: Power Line (identical functional classification)
• Number of Lines: 2 (electrical configuration requirement)
• Current Rating (Max): 4.7A (load capacity specification)
• DC Resistance (DCR) (Max): 40mOhm (electrical performance specification)
• Operating Temperature Range: -40°C ~ 120°C (thermal operating envelope)
• Mounting Type: Surface Mount (assembly compatibility)
• Physical Dimensions: 0.770" L x 0.670" W x 0.390" H maximum (PCB layout constraint)
• Package / Case: Horizontal, 4 PC Pad (footprint compatibility)

The P0422NLT meets all substitution criteria as a direct equivalent manufactured by Pulse Electronics with identical electrical and mechanical specifications. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The P0422NLT is the direct substitute for the obsolete P0422T. Both components are manufactured by Pulse Electronics and share identical electrical specifications (4.7A current rating, 40mOhm DCR) and mechanical dimensions (0.770" x 0.670" x 0.390" maximum height). The components are footprint-compatible with identical 4-pad horizontal package configurations.

The P0422NLT carries Active product status, ensuring long-term availability and supply chain continuity. The P0422NLT is ROHS3 compliant, whereas the P0422T is RoHS non-compliant. The P0422NLT is supplied in Tape & Reel (TR) packaging format, which is standard for automated assembly operations, compared to the P0422T bulk packaging format.

Frequently Asked Questions (FAQ)

Q: Can the P0422NLT be used as a direct replacement for the P0422T?

A: Yes. The P0422NLT is electrically and mechanically equivalent to the P0422T. Both components feature identical current ratings (4.7A), DC resistance (40mOhm), operating temperature range (-40°C to 120°C), and physical dimensions (0.770" L x 0.670" W x 0.390" H maximum). The footprint and pad configuration are identical, enabling direct PCB substitution.

Q: What is the difference between the P0422T and P0422NLT?

A: The primary differences are product status, packaging format, and regulatory compliance. The P0422T is obsolete and supplied in bulk packaging, while the P0422NLT is active and supplied in Tape & Reel (TR) format. The P0422NLT is ROHS3 compliant, whereas the P0422T is RoHS non-compliant.

Q: Is the Tape & Reel packaging of the P0422NLT compatible with automated assembly?

A: Yes. Tape & Reel (TR) packaging is the standard format for automated surface mount assembly operations. The P0422NLT in TR format is suitable for high-volume production environments.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both the P0422T and P0422NLT operate across the identical temperature range (-40°C to 120°C) and maintain the same electrical specifications: 4.7A maximum current rating and 40mOhm maximum DC resistance.

Q: What is the moisture sensitivity level for these components?

A: Both the P0422T and P0422NLT have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without moisture control requirements.
