PE-63387 Pulse Transformer 1:1:1 1.5mH Equivalent & Substitute Parts

Part Overview

The PE-63387 is a 1.5mH pulse transformer with 1:1:1 turns ratio configuration, designed for through-hole mounting applications. This component features a compact form factor of 1.090" L x 0.750" W with a maximum seated height of 1.200". The PE-63387 is classified as obsolete, making identification of suitable alternatives essential for ongoing design support and production continuity. The active substitute PE-63387NL provides functional equivalence with improved compliance status.

Substitute Part Grouping Explanation

The PE-63387NL qualifies as a direct substitute based on strict parameter equivalence across all critical electrical and mechanical specifications. Substitution is valid when the following parameters match identically:

• Inductance: 1.5mH (identical)
• ET (Volt-Time): 320VµS (identical)
• Turns Ratio: 1:1:1 (identical)
• Mounting Type: Through Hole (identical)
• Physical Dimensions: 1.090" L x 0.750" W x 1.200" H max (identical)
• Operating Temperature Range: 0°C ~ 70°C (identical)
• MSL Rating: 1 (Unlimited) (identical)

The PE-63387NL maintains full functional and mechanical compatibility with the obsolete PE-63387, with the primary distinction being packaging format (Tray vs. standard packaging) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The PE-63387NL is the appropriate selection for new designs and production continuity applications. This part maintains complete electrical and mechanical equivalence to the obsolete PE-63387 while offering active product status and ROHS3 compliance. The transition from RoHS non-compliant to ROHS3 compliant status aligns with current regulatory requirements for electronic component manufacturing and distribution.

Both parts share identical REACH and ECCN classifications, confirming regulatory consistency across the substitution. The packaging format difference (Tray for PE-63387NL) does not affect functional performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can PE-63387NL be used as a direct replacement for PE-63387 in existing designs?

A: Yes. The PE-63387NL provides complete functional and mechanical equivalence. All critical parameters—inductance, ET rating, turns ratio, mounting type, and physical dimensions—are identical. The component will integrate into existing PCB layouts and circuit designs without modification.

Q: What is the significance of the RoHS compliance difference?

A: The PE-63387 is RoHS non-compliant, while PE-63387NL is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, PE-63387NL is the required selection. Both parts maintain identical REACH status.

Q: Does the packaging format (Tray vs. standard) affect component performance?

A: No. Packaging format affects only handling, storage, and logistics. The electrical and mechanical characteristics of the transformer remain unchanged. PE-63387NL is supplied in Tray packaging, which is standard for active production components.

Q: Are there any temperature or environmental operating differences between these parts?

A: No. Both parts operate identically across the 0°C to 70°C temperature range and share MSL 1 (Unlimited) moisture sensitivity rating, indicating equivalent environmental performance.

Q: Why is PE-63387 classified as obsolete?

A: The PE-63387 has been superseded by the PE-63387NL, which offers improved compliance status and active manufacturing support. For new procurement and design work, PE-63387NL is the current production equivalent.
