Key Parameters

Substitute Part Grouping Explanation

The PE-65778NL qualifies as a direct substitute based on the following critical parameters:

• Inductance: Identical at 1.2mH
• Turns Ratio: Identical at 1CT:1CT
• Mounting Type: Identical through-hole configuration
• Physical Dimensions: Identical footprint (0.500" L x 0.350" W x 0.250" H max)
• Operating Temperature Range: Identical -40°C ~ 85°C
• Moisture Sensitivity Level: Identical MSL 1 (Unlimited)

The PE-65778NL maintains full electrical and mechanical compatibility with the original PE-65778 while offering improved product status (Active vs. Obsolete) and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The PE-65778NL is the appropriate selection for new designs and production continuity. The original PE-65778 is obsolete and no longer actively manufactured. The PE-65778NL provides identical electrical performance and mechanical compatibility while offering active product status and ROHS3 compliance certification. For applications requiring RoHS non-compliant components, the PE-65778 may be sourced from existing inventory; however, long-term availability is not assured.

Frequently Asked Questions (FAQ)

Q: Can PE-65778NL be used as a direct replacement for PE-65778 in existing designs?

A: Yes. The PE-65778NL is electrically and mechanically identical to the PE-65778. All critical parameters—inductance (1.2mH), turns ratio (1CT:1CT), physical dimensions, operating temperature range, and MSL rating—are identical. PCB layout and circuit design require no modification.

Q: What is the primary difference between PE-65778 and PE-65778NL?

A: The PE-65778NL is the active production equivalent. The original PE-65778 is obsolete. Additionally, the PE-65778NL carries ROHS3 compliance certification, whereas the PE-65778 is RoHS non-compliant. Both parts share identical electrical specifications and physical footprints.

Q: Are there packaging differences between these parts?

A: The PE-65778NL is supplied in Tube packaging. Packaging format does not affect electrical or mechanical performance and does not impact PCB assembly compatibility.

Q: What is the MSL rating for these transformers?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are these parts subject to export control restrictions?

A: Both parts are classified under ECCN EAR99, indicating standard commercial classification with no additional export restrictions beyond normal regulatory requirements.
