KEMET SH-212 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The KEMET SH-212 is a 2-line common mode choke designed for power line filtering applications. This through-hole mounted component operates at 1.5 µH inductance at 100 kHz with a maximum current rating of 3A and DC resistance of 23 mOhm. The part is currently active in production and ROHS3 compliant. Substitute parts are identified based on matching electrical and mechanical parameters within the KEMET SH series to support design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SH-212 are selected based on strict parameter matching within the KEMET SH series. The primary substitution criteria are:

Critical Parameters for Substitution:

• Number of Lines: 2 (all substitutes maintain this requirement)
• Current Rating (Max): 3A (all substitutes maintain this requirement)
• Voltage Rating - DC: 150V (all substitutes maintain this requirement)
• Mounting Type: Through Hole (all substitutes maintain this requirement)
• Package / Case: Vertical, 4 PC Pin (all substitutes maintain this requirement)
• Operating Temperature Range: -25°C to 80°C (all substitutes maintain this requirement)
• RoHS Status: ROHS3 Compliant (all substitutes maintain this requirement)

Variable Parameters Allowing Substitution:

• Inductance @ 100 kHz: 1.5 µH (SH-212), 1.5 µH (SH-102), 1.5 µH (SH-202), 7.5 µH (SH-302), 3.2 µH (SH-311)
• DC Resistance (Max): 23 mOhm (SH-212), 26 mOhm (SH-102), 20 mOhm (SH-202), 26 mOhm (SH-302), 25 mOhm (SH-311)
• Physical Dimensions: Variations in length, width, and height across substitute models

Substitutes SH-102 and SH-202 share identical inductance (1.5 µH @ 100 kHz) with the main part SH-212, differing only in DC resistance and physical dimensions. Substitutes SH-302 and SH-311 offer alternative inductance values (7.5 µH and 3.2 µH respectively) for applications requiring different filtering characteristics while maintaining all other critical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity. Selection between SH-212 and its substitutes depends on application-specific requirements:

For 1.5 µH Inductance Applications: SH-102 and SH-202 are direct inductance equivalents to SH-212. SH-202 offers the lowest DC resistance at 20 mOhm, reducing power dissipation. SH-102 provides a compact footprint with slightly higher DC resistance at 26 mOhm. SH-212 maintains intermediate DC resistance at 23 mOhm with larger physical dimensions.

For Alternative Inductance Values: SH-311 provides 3.2 µH inductance with physical dimensions matching SH-212 (0.551" L x 0.472" W, 0.374" H). SH-302 offers 7.5 µH inductance in a smaller footprint (0.492" L x 0.394" W, 0.472" H) for applications requiring higher filtering attenuation.

All parts maintain identical current rating (3A), voltage rating (150V DC), operating temperature range (-25°C to 80°C), and mounting configuration (through-hole, vertical 4-pin package).

Frequently Asked Questions (FAQ)

Q: Can SH-102 directly replace SH-212 in my circuit? A: SH-102 shares the same inductance (1.5 µH @ 100 kHz), current rating (3A), voltage rating (150V), and operating temperature range as SH-212. The primary differences are DC resistance (26 mOhm vs. 23 mOhm) and physical dimensions. Verify PCB layout compatibility before substitution, as SH-102 is smaller (0.492" L x 0.394" W vs. 0.551" L x 0.472" W).

Q: What is the difference between SH-202 and SH-212? A: Both parts have identical inductance (1.5 µH @ 100 kHz) and current rating (3A). SH-202 has lower DC resistance (20 mOhm vs. 23 mOhm), resulting in reduced power dissipation. Physical dimensions are identical to SH-102 (0.492" L x 0.394" W, 0.472" H), differing from SH-212 (0.551" L x 0.472" W, 0.374" H).

Q: When should I use SH-302 instead of SH-212? A: SH-302 provides 7.5 µH inductance compared to SH-212's 1.5 µH. Use SH-302 when your application requires higher filtering attenuation at the cost of increased inductance. All other electrical parameters (3A current, 150V voltage, -25°C to 80°C temperature range) remain identical.

Q: Are all substitute parts ROHS3 compliant? A: Yes. SH-212, SH-102, SH-202, SH-302, and SH-311 are all ROHS3 compliant and maintain active product status.

Q: How do physical dimensions affect substitution? A: Physical dimensions vary across the substitute parts. SH-212 and SH-311 share larger dimensions (0.551" L x 0.472" W), while SH-102, SH-202, and SH-302 use a smaller footprint (0.492" L x 0.394" W). Verify PCB layout and mounting hole spacing before selecting a substitute with different dimensions.

Q: Which substitute has the lowest DC resistance? A: SH-202 has the lowest DC resistance at 20 mOhm, compared to SH-212 at 23 mOhm, SH-311 at 25 mOhm, and SH-102 and SH-302 at 26 mOhm each. Lower DC resistance reduces power dissipation in high-current applications.
