PE-68422 Equivalent & Substitute Parts

Part Overview

The PE-68422 is a flyback transformer designed for 100 kHz switching applications in DC/DC converter circuits. This surface mount component provides 1500Vrms isolation and operates across a primary voltage range of 18–36V, making it suitable for SMPS (Switched-Mode Power Supply) implementations using National Semiconductor chipsets including the LM2585, LM2586, LM2587, and LM2588 families. The part is currently in active production status with 997 units available in stock. Substitute parts are identified when packaging or inventory requirements differ while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PE-68422 is determined by strict equivalence across the following critical parameters:

• Primary voltage range: 18–36V
• Isolation voltage: 1500Vrms
• Mounting configuration: Surface Mount
• Physical footprint: 0.970" L × 1.070" W (24.64mm × 27.18mm)
• Height constraint: 0.680" maximum seated height
• Operating temperature range: –40°C to +130°C
• Intended chipset compatibility: LM2585, LM2586, LM2587, LM2588
• Regulatory compliance: ROHS3, REACH Unaffected

The PE-68422NL is classified as a direct substitute. It maintains identical electrical specifications, mechanical dimensions, and regulatory certifications. The only distinction is packaging format: PE-68422NL is supplied in Tray packaging, whereas the primary PE-68422 uses standard packaging. Both parts are manufactured by Pulse Electronics and carry active product status.

Parameter Comparison

Engineering Selection Recommendations

Both PE-68422 and PE-68422NL are active production components manufactured by Pulse Electronics with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements and inventory availability:

• PE-68422 is recommended for applications requiring standard packaging format with current inventory of 997 units.
• PE-68422NL is recommended for applications requiring Tray packaging format with current inventory of 967 units.

Both parts satisfy identical electrical and mechanical requirements for flyback converter applications using LM2585, LM2586, LM2587, and LM2588 chipsets. No performance or reliability differences exist between the two variants.

Frequently Asked Questions (FAQ)

Q: Can PE-68422NL be used as a direct replacement for PE-68422?

A: Yes. PE-68422NL is a direct electrical and mechanical equivalent. The only difference is packaging format (Tray versus standard). Both parts maintain identical specifications for primary voltage (18–36V), isolation voltage (1500Vrms), operating temperature range (–40°C to +130°C), physical dimensions, and regulatory compliance.

Q: What determines substitution eligibility for this transformer?

A: Substitution is valid when the following parameters match: primary voltage range, isolation voltage rating, mounting type, physical footprint, maximum seated height, operating temperature range, and intended chipset compatibility. Packaging format differences do not affect electrical or mechanical substitution eligibility.

Q: Are there any compliance or regulatory differences between PE-68422 and PE-68422NL?

A: No. Both parts carry identical ROHS3 compliance status and REACH unaffected designation. No regulatory or environmental compliance differences exist.

Q: What is the significance of the Tray packaging option?

A: Tray packaging (PE-68422NL) is used for bulk handling and automated assembly processes. Standard packaging (PE-68422) is used for general distribution. The choice depends on manufacturing process requirements and supply chain logistics, not component performance.

Q: Are both parts currently available?

A: Yes. PE-68422 has 997 units in stock, and PE-68422NL has 967 units in stock. Both are classified as new original inventory.
