P0473T Common Mode Choke Equivalent & Substitute Parts

Part Overview

The P0473T is a 2-line common mode choke (CMC) designed for power line filtering applications in surface mount configurations. This component features a 1.63A maximum current rating and 110mOhm DC resistance, housed in a compact 0.500" × 0.500" (12.70mm × 12.70mm) package with 0.220" maximum height.

The P0473T carries an obsolete product status. Locating equivalent or substitute components is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or repair requirements for systems utilizing this component.

Substitute Part Grouping Explanation

Substitution of the P0473T 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): 1.63A (thermal and current handling capacity)
• DC Resistance (DCR) (Max): 110mOhm (electrical performance specification)
• Operating Temperature Range: -40°C to 120°C (environmental operating limits)
• Mounting Type: Surface Mount (assembly compatibility)
• Package / Case: Horizontal, 4 PC Pad (footprint and pad configuration)
• Size / Dimension: 0.500" L × 0.500" W (12.70mm × 12.70mm) (PCB layout compatibility)

The P0473NLT meets all substitution criteria as a direct equivalent from the same manufacturer (Pulse Electronics) with identical electrical specifications and mechanical dimensions.

Engineering Selection Recommendations

The P0473NLT is a direct functional and mechanical equivalent to the P0473T. Selection of the P0473NLT is supported by the following factors:

• Electrical Equivalence: Identical current rating, DC resistance, and operating temperature specifications ensure equivalent performance in power line filtering applications.
• Mechanical Compatibility: Matching footprint dimensions (0.500" × 0.500"), pad configuration (Horizontal, 4 PC Pad), and compatible height (P0473NLT at 0.215" is within acceptable tolerance for surface mount assembly) confirm PCB layout compatibility.
• Product Status: The P0473NLT is in active production status, ensuring long-term availability and supply chain reliability compared to the obsolete P0473T.
• Regulatory Compliance: The P0473NLT meets ROHS3 compliance requirements, whereas the P0473T is non-compliant. For applications subject to RoHS regulations, the P0473NLT is the appropriate selection.
• Packaging Availability: The P0473NLT is available in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both prototype and production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the P0473NLT be used as a direct replacement for the P0473T in existing designs?

A: Yes. The P0473NLT meets all critical electrical and mechanical parameters required for direct substitution. The identical current rating (1.63A), DC resistance (110mOhm), operating temperature range (-40°C to 120°C), and footprint dimensions (0.500" × 0.500") confirm functional equivalence. The P0473NLT's slightly lower profile (0.215" vs. 0.220") is compatible with standard surface mount assembly processes.

Q: What is the primary advantage of selecting the P0473NLT over the P0473T?

A: The P0473NLT is in active production status, ensuring reliable supply availability. Additionally, the P0473NLT meets ROHS3 compliance requirements, making it suitable for applications subject to RoHS regulations. The P0473T is obsolete and non-compliant.

Q: Are there any height or clearance concerns when substituting the P0473NLT for the P0473T?

A: No. The P0473NLT maximum height of 0.215" (5.46mm) is lower than the P0473T at 0.220" (5.59mm), providing improved clearance margins in space-constrained applications. Both components use identical horizontal, 4 PC pad package configurations.

Q: What packaging options are available for the P0473NLT?

A: The P0473NLT is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both prototype development and production volume orders.

Q: Are the electrical performance characteristics identical between the P0473T and P0473NLT?

A: Yes. Both components share identical specifications for filter type (Power Line), number of lines (2), current rating (1.63A maximum), DC resistance (110mOhm maximum), and operating temperature range (-40°C to 120°C).
