PE-67100 Current Sense Transformer Equivalent & Substitute Parts

Part Overview

The PE-67100 is a 37 A current sense transformer designed for invasive current measurement applications operating in the 10kHz to 200kHz frequency range. This component features a through-hole mounting configuration with a secondary DC resistance of 1.4Ohm maximum and 20 mH inductance. The PE-67100 is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PE-67100 is based on strict equivalence of the following electrical and mechanical parameters:

• Current rating of 37 A minimum
• Frequency range covering 10kHz to 200kHz operation
• Current ratio of 100:1
• Inductance of 20 mH
• Secondary DC resistance of 1.4Ohm maximum
• Through-hole mounting configuration with PC pin termination
• Physical dimensions compatible with 0.750" height seated maximum
• Moisture sensitivity level of 1 (Unlimited)

The PE-67100NL satisfies all substitution criteria as a direct equivalent from the same manufacturer, Pulse Electronics, with identical electrical performance specifications and compatible mechanical form factor.

Parameter Comparison

Engineering Selection Recommendations

The PE-67100NL is the direct substitute for the obsolete PE-67100. Both components are manufactured by Pulse Electronics and share identical electrical specifications and mechanical form factors. The PE-67100NL is currently in active production status with 731 pieces available in inventory.

The PE-67100NL provides the additional advantage of ROHS3 compliance, whereas the original PE-67100 is RoHS non-compliant. Both components maintain REACH Unaffected status and EAR99 ECCN classification. The substitute part is supplied in tray packaging and maintains the same through-hole PC pin termination configuration, ensuring direct compatibility in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can PE-67100NL be used as a direct replacement for PE-67100?

A: Yes. The PE-67100NL is a direct substitute with identical electrical performance (37 A current rating, 100:1 current ratio, 20 mH inductance, 1.4Ohm secondary resistance) and compatible mechanical specifications (through-hole mounting, PC pin termination, 0.750" seated height). Both components operate across the 10kHz to 200kHz frequency range.

Q: What is the primary difference between PE-67100 and PE-67100NL?

A: The PE-67100NL is the active production variant with ROHS3 compliance. The original PE-67100 is obsolete and RoHS non-compliant. The substitute includes primary DC resistance specification (56Ohm) in addition to secondary resistance, and is available in tray packaging versus the original packaging configuration.

Q: Are there any dimensional differences between these parts?

A: Both components share the same seated height of 0.750" (19.05mm). The length and width dimensions are transposed (PE-67100: 0.750" L × 0.565" W; PE-67100NL: 0.565" L × 0.750" W), but both fit within the same maximum height envelope and maintain identical PC pin termination spacing for through-hole PCB mounting.

Q: What inventory status should be considered for procurement?

A: PE-67100NL has 731 pieces in stock as new original inventory. The obsolete PE-67100 has 1132 pieces available but is no longer in active production. For new designs and ongoing production, PE-67100NL is the recommended selection.

Q: Are compliance certifications equivalent between the two parts?

A: Both components maintain REACH Unaffected status and EAR99 ECCN classification. The PE-67100NL provides superior compliance with ROHS3 certification, whereas the PE-67100 is RoHS non-compliant. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both parts.
