PE-65857 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The PE-65857 is a 4-line common mode choke (CMC) surface mount component manufactured by Pulse Electronics, designed for signal line filtering applications. This part features a DC resistance of 220mOhm and is packaged in a vertical 8 gull wing configuration with dimensions of 0.475" L x 0.475" W x 0.390" H maximum.

The PE-65857 carries an obsolete product status, making it necessary to identify functionally equivalent alternatives for new designs and ongoing production requirements. Active substitute parts maintain the core electrical and mechanical characteristics while offering improved availability and compliance with current regulatory standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PE-65857 is determined by the following critical parameters:

• Filter Type: Must be Signal Line
• Number of Lines: Must be 4
• Mounting Type: Must be Surface Mount
• Package Configuration: Must be Vertical, 8 Gull Wing
• DC Resistance (DCR): Must be within acceptable tolerance range (220mOhm baseline)

The T8003NL meets all substitution criteria as a parametric equivalent. Both parts share identical filter type, line count, mounting configuration, and package style. The DCR specification of T8003NL (200mOhm maximum) represents a lower resistance value, which is electrically compatible with the original 220mOhm specification and provides improved performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The T8003NL is the qualified substitute for PE-65857 based on the following factors:

Product Status: T8003NL carries active product status, ensuring continued availability and manufacturing support, whereas PE-65857 is obsolete.

Regulatory Compliance: T8003NL is ROHS3 compliant, meeting current environmental and material restriction requirements. PE-65857 is RoHS non-compliant and does not satisfy modern procurement standards.

Electrical Compatibility: The T8003NL DCR specification of 200mOhm is lower than the PE-65857 specification of 220mOhm, providing equivalent or improved performance in signal line filtering applications.

Physical Compatibility: Both parts maintain identical electrical line configuration, mounting type, and package style. T8003NL features a more compact footprint (0.450" L x 0.265" W vs. 0.475" L x 0.475" W) and reduced height (0.220" vs. 0.390"), which may require PCB layout verification for space-constrained applications.

Moisture Sensitivity: T8003NL specifies MSL 3 (168 hours) compared to PE-65857 MSL 1 (unlimited). Standard moisture control procedures during storage and assembly are required.

Frequently Asked Questions (FAQ)

Q: Can T8003NL directly replace PE-65857 in existing designs?

A: T8003NL is electrically and functionally equivalent to PE-65857 for signal line common mode choke applications. Both parts share identical filter type, 4-line configuration, surface mount technology, and vertical 8 gull wing package. PCB layout verification is required due to dimensional differences in footprint and height.

Q: What are the key differences between these parts?

A: The primary differences are product status (T8003NL is active; PE-65857 is obsolete), regulatory compliance (T8003NL is ROHS3 compliant; PE-65857 is not), DC resistance (T8003NL 200mOhm vs. PE-65857 220mOhm), physical dimensions (T8003NL is more compact), and moisture sensitivity level (T8003NL MSL 3 vs. PE-65857 MSL 1).

Q: Are there any compatibility concerns with the smaller footprint of T8003NL?

A: T8003NL has a smaller footprint (0.450" L x 0.265" W) and lower height (0.220") compared to PE-65857 (0.475" L x 0.475" W, 0.390" height). PCB layout and assembly process verification is necessary to confirm compatibility with existing designs.

Q: What moisture handling procedures apply to T8003NL?

A: T8003NL specifies MSL 3 (168 hours), requiring standard moisture control during storage and assembly. Components must be stored in controlled humidity environments and baked according to IPC standards prior to reflow soldering if moisture absorption limits are exceeded.

Q: Is T8003NL available in the same packaging format as PE-65857?

A: T8003NL is supplied in tube packaging, whereas PE-65857 packaging format is not specified in available data. Confirm packaging requirements for your procurement and assembly processes.
