PE-67540 Equivalent & Substitute Parts

Part Overview

The PE-67540 is a 4-line common mode choke (CMC) surface mount component manufactured by Pulse Electronics, designed for signal line filtering applications. With a DC resistance of 600mOhm and vertical 8 gull wing package configuration, this component is classified as obsolete. Due to its obsolete product status, identifying equivalent substitute parts with matching electrical and mechanical specifications is necessary to maintain design continuity and ensure procurement availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PE-67540 is determined by strict equivalence across the following critical parameters:

• Filter Type: Signal Line
• Number of Lines: 4
• DC Resistance (DCR): 600mOhm maximum
• Mounting Type: Surface Mount
• Physical Dimensions: 0.476" L x 0.602" W (12.10mm x 15.30mm)
• Height: 0.350" (8.89mm) maximum
• Package Configuration: Vertical, 8 Gull Wing

The PE-67540NL qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction between the main part and its substitute relates to product status, packaging format, compliance certifications, and moisture sensitivity classification.

Engineering Selection Recommendations

The PE-67540NL is the direct substitute for the obsolete PE-67540. Selection of PE-67540NL is supported by the following factors:

Product Status: PE-67540NL maintains active product status with Pulse Electronics, ensuring ongoing availability and supply chain continuity compared to the obsolete PE-67540.

Compliance Certifications: PE-67540NL achieves RoHS compliance, meeting current regulatory requirements for electronic components in restricted substance directives. The original PE-67540 is RoHS non-compliant.

Moisture Sensitivity: PE-67540NL carries MSL 1 (Unlimited) classification, providing superior moisture handling characteristics and reduced risk during storage and assembly compared to the PE-67540's MSL 3 (168 Hours) rating.

Electrical and Mechanical Equivalence: Both parts maintain identical DC resistance, physical dimensions, height, package configuration, and mounting type, ensuring direct functional compatibility in existing circuit designs.

Regulatory Alignment: Both parts share identical REACH and ECCN classifications, maintaining consistent export and regulatory compliance profiles.

Frequently Asked Questions (FAQ)

Q: Can PE-67540NL be used as a direct replacement for PE-67540 in existing designs?

A: Yes. PE-67540NL is electrically and mechanically equivalent to PE-67540. Both components share identical DC resistance (600mOhm), physical dimensions (0.476" L x 0.602" W, 12.10mm x 15.30mm), height (0.350", 8.89mm), and package configuration (Vertical, 8 Gull Wing). No circuit redesign is required.

Q: What are the key differences between PE-67540 and PE-67540NL?

A: The primary differences are product status, compliance certifications, and moisture sensitivity. PE-67540NL is an active product with RoHS compliance and MSL 1 rating, while PE-67540 is obsolete, RoHS non-compliant, and carries MSL 3 rating. Packaging format differs (Tube for PE-67540NL versus standard for PE-67540).

Q: Why is PE-67540 classified as obsolete?

A: PE-67540 has been discontinued by Pulse Electronics. PE-67540NL represents the current active equivalent, ensuring continued availability and compliance with modern regulatory standards.

Q: Does the MSL 1 rating of PE-67540NL provide advantages over the MSL 3 rating of PE-67540?

A: Yes. MSL 1 (Unlimited) allows indefinite storage without moisture absorption concerns, whereas MSL 3 (168 Hours) requires controlled storage conditions and limits shelf life to 168 hours after moisture exposure. PE-67540NL offers superior handling flexibility and reduced risk of moisture-related failures.

Q: Are there any compliance or certification differences between these parts?

A: Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99). PE-67540NL achieves RoHS compliance, while PE-67540 does not. For applications requiring RoHS compliance, PE-67540NL is the appropriate selection.

Q: What packaging formats are available for these parts?

A: PE-67540 is supplied in standard packaging, while PE-67540NL is supplied in Tube packaging format. Both maintain identical component specifications and performance characteristics.
