PE-53914 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The PE-53914 is a 2-line common mode choke (CMC) designed for power line filtering applications with a 500mA current rating and 850mOhm maximum DC resistance. This surface mount component operates across a temperature range of -40°C to 130°C with a 250V AC voltage rating. The PE-53914 is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PE-53914 is determined by strict equivalence across the following electrical and mechanical parameters:

• Filter Type: Power Line (identical functional classification)
• Number of Lines: 2 (electrical configuration requirement)
• Current Rating (Max): 500mA (load capacity specification)
• DC Resistance (Max): 850mOhm (impedance characteristic)
• Voltage Rating - AC: 250V (voltage withstand requirement)
• Operating Temperature Range: -40°C ~ 130°C (thermal operating envelope)
• Mounting Type: Surface Mount (assembly compatibility)
• Physical Dimensions: 0.645" L x 0.560" W x 0.350" H maximum (PCB layout constraint)
• Package / Case: Horizontal, 4 PC Pad (footprint compatibility)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage requirement)

The PE-53914NL meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The PE-53914NL is the direct substitute for the obsolete PE-53914. Both components are manufactured by Pulse Electronics and maintain identical electrical specifications and physical form factors. The primary distinction is product status: PE-53914NL is active and currently in production, whereas PE-53914 is obsolete.

For new designs or ongoing production requiring compliance with current regulatory standards, PE-53914NL is the appropriate selection. This substitute provides ROHS3 compliance, whereas the original PE-53914 is RoHS non-compliant. Both components maintain REACH Unaffected status and identical moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can PE-53914NL be used as a direct replacement for PE-53914 in existing designs?

A: Yes. PE-53914NL is electrically and mechanically equivalent to PE-53914. Both components share identical current ratings (500mA), DC resistance (850mOhm), voltage ratings (250V AC), operating temperature range (-40°C ~ 130°C), and physical dimensions (0.645" L x 0.560" W x 0.350" H). The footprint and pad configuration are identical, enabling direct PCB substitution without layout modifications.

Q: What is the primary reason for substitution?

A: PE-53914 is classified as obsolete. PE-53914NL is the active production equivalent from the same manufacturer, ensuring long-term component availability and supply chain continuity.

Q: Are there compliance differences between these parts?

A: PE-53914NL is ROHS3 compliant, whereas PE-53914 is RoHS non-compliant. Both maintain REACH Unaffected status. For applications subject to RoHS regulations, PE-53914NL is the required selection.

Q: Do packaging differences affect compatibility?

A: PE-53914 is supplied in standard packaging, while PE-53914NL is supplied in Tube packaging. This distinction affects procurement and handling procedures but does not impact electrical performance or PCB assembly compatibility.

Q: Are the electrical characteristics identical?

A: Yes. Both components are 2-line common mode chokes with 500mA maximum current rating, 850mOhm maximum DC resistance, 250V AC voltage rating, and -40°C to 130°C operating temperature range. Electrical performance is equivalent.
