ET2432-019 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The ET2432-019 is a 2-line common mode choke manufactured by Triad Magnetics, designed for power line filtering applications. This through-hole component features 24 mH inductance at 10 kHz with a 600 mA maximum current rating and 1.6 Ohm DC resistance. The part is actively produced and maintains full compliance with RoHS3, CSA, IEC, and UL standards. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowed parameter ranges for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ET2432-019 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Filter Type: Power Line
• Number of Lines: 2
• Mounting Type: Through Hole
• Package / Case: Vertical, 4 PC Pin
• Voltage Rating - AC: 250 V
• Operating Temperature Range: -20°C to 105°C
• Compliance: CSA, IEC, UL certifications
• RoHS Status: ROHS3 Compliant

Allowable Parameter Variation:

• Inductance @ 10 kHz: May exceed 24 mH
• Current Rating (Max): Must equal or exceed 600 mA
• DC Resistance (Max): Must not exceed 1.6 Ohm
• Physical dimensions: May vary within through-hole mounting constraints

The ET2835-036 qualifies as a parametric equivalent because it maintains all mandatory matching criteria while providing higher inductance (66 mH), increased current capacity (700 mA), and lower DC resistance (1.5 Ohm).

Parameter Comparison

Engineering Selection Recommendations

Both the ET2432-019 and ET2835-036 are active products with identical compliance certifications (CSA, IEC, UL) and RoHS3 status. Selection between these parts depends on circuit requirements:

ET2432-019 Selection Criteria:

• Applications requiring exactly 24 mH inductance at 10 kHz
• Circuits designed for 600 mA maximum current
• Space-constrained designs (smaller footprint: 19.48 mm L × 26.42 mm W)

ET2835-036 Selection Criteria:

• Applications tolerating or requiring higher inductance (66 mH)
• Circuits benefiting from increased current capacity (700 mA)
• Designs where lower DC resistance (1.5 Ohm vs. 1.6 Ohm) reduces power dissipation
• Applications with available board space for larger component (31.50 mm L × 23.49 mm W)

Both parts maintain identical voltage ratings, temperature ranges, and regulatory compliance. The choice between them is determined by specific circuit inductance requirements and current handling needs.

Frequently Asked Questions (FAQ)

Q: Can ET2835-036 be used as a direct replacement for ET2432-019?

A: ET2835-036 is a parametric equivalent, not a direct pin-for-pin replacement. Both parts use identical through-hole vertical 4-pin packaging and mounting type. However, ET2835-036 has higher inductance (66 mH vs. 24 mH) and different physical dimensions. Substitution is valid only if the circuit design accommodates the higher inductance value and the larger footprint (31.50 mm L × 23.49 mm W vs. 19.48 mm L × 26.42 mm W).

Q: What are the key differences between these two parts?

A: The primary differences are inductance (24 mH vs. 66 mH at 10 kHz), current rating (600 mA vs. 700 mA), DC resistance (1.6 Ohm vs. 1.5 Ohm), and physical dimensions. All other parameters—filter type, line count, voltage rating, temperature range, mounting type, and certifications—are identical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both ET2432-019 and ET2835-036 are ROHS3 compliant and carry identical regulatory approvals from CSA, IEC, and UL.

Q: What is the voltage rating for both parts?

A: Both parts have an AC voltage rating of 250 V and operate across the temperature range of -20°C to 105°C.

Q: Can these parts be used interchangeably in all applications?

A: No. Interchangeability depends on circuit inductance requirements. ET2835-036 provides 2.75 times higher inductance than ET2432-019. Use ET2835-036 only in applications where the higher inductance value is acceptable or beneficial. For circuits requiring exactly 24 mH, use ET2432-019.

Q: What is the physical footprint difference?

A: ET2432-019 measures 19.48 mm L × 26.42 mm W × 31.00 mm H. ET2835-036 measures 31.50 mm L × 23.49 mm W × 37.00 mm H. Both use vertical through-hole mounting with 4 pins.
