PE-65855 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The PE-65855 is a 2-line common mode choke (CMC) surface mount component manufactured by Pulse Electronics, designed for signal line filtering applications. With a DC resistance (DCR) of 1Ohm maximum and horizontal 4-pad configuration, this component is used in electromagnetic interference (EMI) suppression circuits.

The PE-65855 carries an obsolete product status. Identifying functionally equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for legacy systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PE-65855 is determined by strict equivalence across the following critical parameters:

• Manufacturer: Pulse Electronics (same manufacturer ensures design compatibility)
• Filter Type: Signal Line (functional application category)
• Number of Lines: 2 (electrical configuration)
• DC Resistance (DCR) Max: 1Ohm (electrical performance specification)
• Mounting Type: Surface Mount (assembly compatibility)
• Physical Dimensions: 0.400" L x 0.345" W, Height 0.250" max (PCB layout compatibility)
• Package / Case: Horizontal, 4 PC Pad (footprint and pad configuration)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage requirements)

The PE-65855NL meets all substitution criteria as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The PE-65855NL is a direct functional equivalent to the PE-65855. Both parts share identical electrical specifications (2-line configuration, 1Ohm DCR maximum), mechanical dimensions, and mounting characteristics.

The PE-65855NL offers two significant advantages:

• Product Status: Active status ensures ongoing availability and supply chain support, eliminating obsolescence risk associated with the PE-65855.
• RoHS Compliance: The PE-65855NL meets RoHS requirements, supporting compliance with current environmental and regulatory standards.

Selection of PE-65855NL is appropriate for new designs and production continuity of legacy systems where component substitution is required.

Frequently Asked Questions (FAQ)

Q: Can PE-65855NL be used as a direct replacement for PE-65855 in existing designs?

A: Yes. Both parts are identical in electrical performance (2-line CMC, 1Ohm DCR), physical dimensions (0.400" x 0.345" x 0.250" max height), and package configuration (Horizontal, 4 PC Pad). PCB layouts and assembly processes require no modification.

Q: What is the difference between PE-65855 and PE-65855NL?

A: The parts are electrically and mechanically equivalent. Differences are limited to product status (Obsolete vs. Active), RoHS compliance status (non-compliant vs. compliant), and packaging format (unspecified vs. Tube).

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance reflects material composition and manufacturing process standards, not electrical or mechanical performance. Both parts meet identical functional specifications.

Q: Are there any compatibility concerns with PCB assembly?

A: No. Identical dimensions, height specifications, and pad configuration (Horizontal, 4 PC Pad) ensure full compatibility with existing PCB designs and assembly equipment.

Q: What packaging is available for PE-65855NL?

A: PE-65855NL is supplied in Tube packaging. Confirm packaging requirements with your procurement process.
