Substitute Part Grouping Explanation

Substitution eligibility for the PE-51719 is determined by strict equivalence across the following critical parameters:

• Current Rating: 20 A (exact match required)
• Frequency Range: 20kHz – 200kHz (exact match required)
• Inductance: 80 mH (exact match required)
• Current Ratio: 200CT:1 (exact match required)
• Type: Non-Invasive (Solid Core) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination Style: PC Pin (exact match required)
• Physical Dimensions: 0.900" L × 0.700" W (exact match required)

The PE-51719NL meets all substitution criteria as a direct equivalent manufactured by Pulse Electronics with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The PE-51719NL is the direct substitute for the obsolete PE-51719. Both components are manufactured by Pulse Electronics and share identical electrical and mechanical specifications, ensuring pin-for-pin and form-factor compatibility.

• Tray packaging supports automated assembly processes
• Identical performance characteristics eliminate the need for circuit redesign or re-qualification

For applications currently using the PE-51719, direct substitution with PE-51719NL requires no circuit modifications or performance re-evaluation.

Frequently Asked Questions (FAQ)

Q: Can PE-51719NL be used as a direct replacement for PE-51719?

A: Yes. The PE-51719NL is a direct substitute with identical current rating (20 A), frequency range (20kHz – 200kHz), inductance (80 mH), current ratio (200CT:1), mounting type (through hole), termination style (PC pin), and physical dimensions. No circuit modifications are required.

Q: What is the primary difference between PE-51719 and PE-51719NL?

A: The PE-51719NL is the active production equivalent of the obsolete PE-51719. The primary differences are product status (active vs. obsolete), RoHS compliance (ROHS3 compliant vs. non-compliant), and packaging format (tray vs. bulk).

Q: Are there any compatibility concerns when switching from PE-51719 to PE-51719NL?

A: No compatibility concerns exist. Both components are manufactured by Pulse Electronics with identical electrical performance and mechanical form factors. The PE-51719NL is suitable for direct PCB assembly without design changes.

Q: What packaging options are available for PE-51719NL?

A: The PE-51719NL is supplied in tray packaging, which is standard for automated assembly operations and provides improved component protection compared to bulk packaging.

Q: Does PE-51719NL meet current regulatory compliance standards?

A: Yes. The PE-51719NL is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in most markets.
