KEMET SH-102 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The KEMET SH-102 is a 2-line common mode choke (CMC) designed for power line filtering applications. This through-hole component operates at 1.5 µH inductance at 100 kHz with a 3A maximum current rating and 26 mOhm DC resistance. The part is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component interchangeability in circuit designs where the primary part becomes unavailable or inventory constraints exist.

Substitute Part Grouping Explanation

Substitute parts for the SH-102 are identified based on strict parameter alignment within the KEMET SH series common mode choke product line. The substitution logic is based on the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: KEMET (same manufacturer)
• Series: SH (same product series)
• Filter Type: Power Line (same application category)
• Number of Lines: 2 (identical configuration)
• Current Rating (Max): 3A (identical current capacity)
• Voltage Rating - DC: 150V (identical voltage specification)
• Mounting Type: Through Hole (identical mounting method)
• Package / Case: Vertical, 4 PC Pin (identical pin configuration)
• Operating Temperature Range: -25°C to 80°C (identical thermal range)
• RoHS Status: ROHS3 Compliant (identical compliance)
• Product Status: Active (current production status)

Variable Parameters Allowing Substitution:

• Inductance @ 100 kHz (1.5 µH, 3.2 µH, or 7.5 µH)
• DC Resistance (Max) (25 mOhm or 26 mOhm)
• Physical Dimensions (size and height variations)

Substitute parts SH-302 and SH-311 maintain all critical electrical and mechanical parameters while offering different inductance values and minor resistance/dimensional variations. These parts are direct substitutes when circuit design permits inductance value flexibility within the specified range.

Parameter Comparison

Engineering Selection Recommendations

SH-102 Primary Selection: The SH-102 is the specified component for applications requiring 1.5 µH inductance at 100 kHz. All parts maintain Active product status with ROHS3 compliance and identical electrical ratings (3A, 150V DC, 26 mOhm DCR).

SH-302 Substitution: The SH-302 provides 7.5 µH inductance at 100 kHz with identical current, voltage, and resistance specifications. Physical dimensions remain unchanged (12.5mm x 10.00mm x 12.00mm height). This substitute is applicable when higher inductance filtering is acceptable within circuit design parameters. Inventory availability is 4866 pieces.

SH-311 Substitution: The SH-311 provides 3.2 µH inductance at 100 kHz with marginally lower DC resistance (25 mOhm versus 26 mOhm). Physical dimensions differ: 14.00mm x 12.00mm footprint with 9.50mm height. This substitute accommodates applications requiring intermediate inductance values and reduced thermal dissipation. Inventory availability is 733 pieces.

All substitute parts maintain identical compliance certifications (ROHS3, REACH Unaffected, EAR99, HTSUS 8548.00.0000) and thermal operating range (-25°C to 80°C).

Frequently Asked Questions (FAQ)

Q: Can SH-302 replace SH-102 in any application? A: SH-302 substitution is valid when circuit design permits 7.5 µH inductance instead of 1.5 µH. All electrical ratings (3A current, 150V voltage, 26 mOhm resistance) and compliance specifications are identical. Physical dimensions remain unchanged.

Q: What is the primary difference between SH-311 and SH-102? A: SH-311 provides 3.2 µH inductance (versus 1.5 µH), slightly lower DC resistance (25 mOhm versus 26 mOhm), and different physical dimensions (14.00mm x 12.00mm footprint, 9.50mm height versus 12.5mm x 10.00mm footprint, 12.00mm height). Current and voltage ratings remain identical at 3A and 150V DC.

Q: Are all three parts pin-compatible? A: Yes. All three parts (SH-102, SH-302, SH-311) use identical Vertical, 4 PC Pin package configuration and through-hole mounting type, ensuring mechanical compatibility in PCB layouts.

Q: Do substitute parts require design verification? A: Substitution validity depends on circuit inductance requirements. SH-102 (1.5 µH), SH-311 (3.2 µH), and SH-302 (7.5 µH) represent different inductance values within the same product family. Circuit design must accommodate the selected inductance value.

Q: What is the inventory status of each part? A: SH-102 has 951 pieces in stock, SH-302 has 4866 pieces, and SH-311 has 733 pieces available as new original inventory.

Q: Are all parts ROHS3 compliant? A: Yes. SH-102, SH-302, and SH-311 are all ROHS3 compliant with REACH Unaffected status and identical regulatory classifications (EAR99, HTSUS 8548.00.0000).

Q: What is the operating temperature range for all substitute parts? A: All three parts operate within -25°C to 80°C temperature range with identical thermal specifications.
