PE-61017 Pulse Transformer 2:1 1mH Equivalent & Substitute Parts

Part Overview

The PE-61017 is a 1mH pulse transformer with a 2:1 turns ratio manufactured by Pulse Electronics, designed for through-hole mounting applications. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design requirements and production continuity. The transformer operates across a 0°C to 70°C temperature range with a volt-time product of 700VµS and is non-RoHS compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PE-61017 is determined by the following critical parameters:

• Turns Ratio: Must be 2:1 (primary to secondary)
• Mounting Type: Must be through-hole configuration
• Volt-Time Product (ET): Electrical performance indicator for pulse transformer applications
• Operating Temperature Range: Must accommodate or exceed the 0°C to 70°C specification
• Compliance Status: RoHS and REACH certifications for regulatory alignment

The IT246 qualifies as a substitute based on matching turns ratio (2:1) and through-hole mounting. However, differences in inductance (7mH vs. 1mH), ET rating, physical dimensions, and compliance status must be evaluated against specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The IT246 is an active product with ROHS3 compliance, addressing the obsolescence and regulatory limitations of the PE-61017. The IT246 operates across an extended temperature range (-25°C to 70°C), providing broader environmental tolerance. However, the inductance difference (7mH vs. 1mH) and unspecified ET rating require circuit-level validation to confirm functional equivalence. The reduced physical footprint of the IT246 may provide layout advantages in space-constrained applications. Selection should be based on whether the higher inductance and modified electrical characteristics align with the target circuit's performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the IT246 directly replace the PE-61017 in all applications?

A: Direct replacement depends on circuit tolerance to the inductance difference (7mH vs. 1mH) and the unspecified ET rating of the IT246. The matching 2:1 turns ratio and through-hole mounting enable physical substitution, but electrical performance validation is required.

Q: What is the significance of the ET (Volt-Time) parameter?

A: The ET rating defines the maximum volt-time product the transformer core can handle before saturation. The PE-61017 specifies 700VµS; the IT246 ET value is not provided, requiring verification against circuit requirements.

Q: Does the IT246's higher inductance (7mH) affect compatibility?

A: Higher inductance alters impedance and frequency response characteristics. Applications sensitive to these parameters must evaluate whether the 7mH specification meets design specifications.

Q: What are the compliance implications of switching from PE-61017 to IT246?

A: The IT246 is ROHS3 compliant, whereas the PE-61017 is non-compliant. This transition supports regulatory requirements for new designs and manufacturing environments with RoHS mandates.

Q: Are there physical installation differences between these parts?

A: The IT246 is significantly smaller (0.445" height vs. 0.821" height) and lighter (0.2 oz vs. unspecified weight). PCB layout and mechanical clearance must be verified for the reduced footprint.
