SH-432 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The SH-432 is a 30 µH Common Mode Choke (CMC) manufactured by KEMET, designed for power line filtering applications. This through-hole component operates at 2.4A maximum current with a DC resistance of 51 mOhm and is rated for 50V DC operation across a temperature range of -25°C to 60°C. The component is ROHS3 compliant and currently maintains active product status with 1,032 units in stock.

Common Mode Chokes are essential filtering components in power distribution circuits, EMI suppression networks, and signal integrity applications. Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while preserving mechanical compatibility and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SH-432 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Current Rating (Maximum): Must equal or exceed 2.4A
• DC Resistance (Maximum): Must not exceed 51 mOhm
• Voltage Rating (DC): Must equal or exceed 50V
• Number of Lines: Must equal 2
• Mounting Type: Must be Through Hole
• Package Configuration: Must be Vertical, 6 PC Pin
• Operating Temperature Range: Must encompass -25°C to 60°C
• RoHS Status: Must maintain ROHS3 Compliance

Functional Parameter:

• Inductance @ 100 kHz: Determines filtering performance; substitutes with different inductance values serve different circuit requirements and are classified separately

The SH-132 is identified as a parametric equivalent based on matching all critical parameters. The inductance value differs (2.6 µH versus 30 µH), indicating application-specific selection rather than direct drop-in replacement.

Parameter Comparison

Engineering Selection Recommendations

SH-432 Selection Criteria: The SH-432 is selected for applications requiring 30 µH inductance at 100 kHz. This inductance value is appropriate for power line filtering in circuits where higher attenuation of common-mode noise is required. The component maintains active product status with robust inventory availability (1,032 units), ensuring supply chain reliability.

SH-132 Selection Criteria: The SH-132 is selected for applications requiring 2.6 µH inductance at 100 kHz. This lower inductance value is suitable for circuits requiring minimal impedance insertion while maintaining common-mode filtering. The component is also active with adequate inventory (845 units).

Compliance Basis: Both components are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronic component deployment in regulated markets. Both maintain identical electrical ratings (2.4A current, 51 mOhm DCR, 50V DC rating) and mechanical specifications (through-hole mounting, vertical 6-pin configuration, identical footprint dimensions).

Selection Logic: Component selection between SH-432 and SH-132 is determined exclusively by the required inductance value for the specific circuit application. Electrical and mechanical compatibility is assured across both parts within the SH series.

Frequently Asked Questions (FAQ)

Q: Can SH-132 be used as a direct replacement for SH-432?

A: No. While both components share identical electrical ratings (2.4A, 51 mOhm DCR, 50V), mechanical compatibility (through-hole, vertical 6-pin), and compliance certifications (ROHS3), they differ in inductance value (2.6 µH versus 30 µH). Direct replacement is only valid if the circuit design specifies 2.6 µH inductance. Inductance mismatch will alter filtering performance and circuit behavior.

Q: Are the physical dimensions identical between SH-432 and SH-132?

A: Yes. Both components share identical footprint dimensions (10.00mm length × 9.00mm width) and maximum height (10.50mm). Both use vertical, 6-pin package configuration. PCB layout compatibility is assured.

Q: What is the significance of the different inductance values?

A: Inductance determines the filtering effectiveness at a given frequency. The 30 µH SH-432 provides higher impedance and greater attenuation of common-mode noise compared to the 2.6 µH SH-132. Selection depends on the circuit's EMI suppression requirements and impedance budget.

Q: Are both parts currently available?

A: Yes. SH-432 has 1,032 units in stock, and SH-132 has 845 units in stock. Both maintain active product status.

Q: Do both components meet the same compliance standards?

A: Yes. Both SH-432 and SH-132 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code (8548.00.0000).

Q: Can these components be used interchangeably in the same circuit?

A: No. Interchangeability is limited to applications where the specific inductance value is not critical to circuit function. In most power line filtering and EMI suppression applications, inductance value is a design-critical parameter. Circuit validation is required before substitution.
