Key Parameters

Substitute Part Grouping Explanation

The PE-65351NL qualifies as a direct substitute based on the following critical parameters that determine functional and mechanical compatibility:

• Inductance: Both parts specify 1.2mH
• Turns Ratio: Both maintain 1:2CT configuration
• Mounting Type: Both are through-hole mounted
• Physical Dimensions: Identical footprint (0.500" L x 0.350" W; 12.70mm x 8.89mm)
• Height: Identical seated height of 0.250" (6.35mm)
• Operating Temperature Range: Both rated 0°C ~ 70°C
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)

The PE-65351NL represents an active product variant with enhanced compliance characteristics, making it suitable for applications requiring current regulatory standards.

Engineering Selection Recommendations

The PE-65351NL is the designated substitute for the obsolete PE-65351. Selection criteria are based on the following factors:

Product Status: The PE-65351 is obsolete, while PE-65351NL maintains active production status, ensuring continued availability and supply chain reliability.

Regulatory Compliance: PE-65351NL achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions. The original PE-65351 is RoHS non-compliant, which may present regulatory barriers in new designs or applications subject to RoHS requirements.

Functional Equivalence: All critical electrical and mechanical parameters are identical between the two parts, including inductance, turns ratio, mounting configuration, and thermal operating range.

Physical Compatibility: Identical dimensions and footprint ensure direct board-level substitution without PCB redesign or mechanical rework.

Frequently Asked Questions (FAQ)

Q: Can PE-65351NL be used as a direct replacement for PE-65351 in existing designs?

A: Yes. The PE-65351NL maintains identical inductance (1.2mH), turns ratio (1:2CT), physical dimensions, and operating temperature range. No circuit modifications or PCB layout changes are required for substitution.

Q: What is the primary difference between PE-65351 and PE-65351NL?

A: The PE-65351NL is an active product variant with ROHS3 compliance, whereas the PE-65351 is obsolete and RoHS non-compliant. Both parts are functionally and mechanically equivalent.

Q: Are there any packaging differences between these parts?

A: The PE-65351NL is supplied in tube packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Does the MSL rating differ between the two parts?

A: No. Both PE-65351 and PE-65351NL are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What export control classifications apply to these parts?

A: Both parts are classified under ECCN EAR99 and HTSUS 8504.31.2000, with identical export control treatment.
