KEMET SH-101 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The KEMET SH-101 is a through-hole mounted common mode choke (CMC) designed for power line filtering applications. This 2-line component provides 0.35 µH inductance at 100 kHz with a maximum current rating of 3A and 16 mOhm DC resistance. The part is currently in active production status with ROHS3 compliance and REACH unaffected classification. Substitute parts are identified when equivalent electrical and mechanical parameters allow direct functional replacement in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KEMET SH-101 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Lines: 2
• Current Rating (Max): 3A
• DC Resistance (Max): 16 mOhm
• Voltage Rating - DC: 150V
• Operating Temperature Range: -25°C to 80°C
• Mounting Type: Through Hole
• Package / Case: Vertical, 4 PC Pin
• Physical Dimensions: 12.5mm L x 10.00mm W x 12.00mm H (Max)
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Allowable Variation Parameter:

• Inductance @ 100 kHz: Substitutes must maintain the same series classification within the SH product line

The SH-201 is classified as a parametric equivalent because it maintains all mandatory electrical and mechanical specifications while operating within the same product series and compliance framework.

Engineering Selection Recommendations

SH-101 Primary Selection: The SH-101 is the specified component when 0.35 µH inductance at 100 kHz is the circuit requirement. This part maintains active production status with full ROHS3 compliance and REACH unaffected classification. Current inventory is 907 pieces.

SH-201 Substitute Selection: The SH-201 is a direct substitute when circuit design allows for 0.5 µH inductance at 100 kHz. All electrical ratings, mechanical dimensions, mounting configuration, and regulatory compliance are identical to the SH-101. The SH-201 has higher inventory availability at 1774 pieces. Both parts are manufactured by KEMET within the same SH series and share identical through-hole vertical mounting specifications.

Compliance Basis: Both parts satisfy ROHS3 compliance requirements and maintain REACH unaffected status. Selection between these parts is based solely on the inductance value required by the circuit application and component availability.

Frequently Asked Questions (FAQ)

Q: Can the SH-201 replace the SH-101 in any application?

A: The SH-201 can replace the SH-101 only when the circuit design accommodates 0.5 µH inductance instead of 0.35 µH. All other electrical parameters (current rating, DC resistance, voltage rating, temperature range) and mechanical specifications (mounting type, package, dimensions) are identical. The substitution is valid only if the higher inductance value does not violate circuit performance requirements.

Q: Are the physical dimensions identical between SH-101 and SH-201?

A: Yes. Both parts have identical dimensions: 12.5mm length, 10.00mm width, and 12.00mm maximum height. Both use vertical 4-pin through-hole mounting. PCB layout and mechanical clearance requirements are identical.

Q: What is the difference between SH-101 and SH-201?

A: The only electrical difference is inductance at 100 kHz: SH-101 provides 0.35 µH while SH-201 provides 0.5 µH. All other specifications including current rating (3A), DC resistance (16 mOhm), voltage rating (150V DC), and operating temperature range (-25°C to 80°C) are identical.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both SH-101 and SH-201 are ROHS3 compliant and REACH unaffected. Both maintain active production status with identical compliance certifications.

Q: Which part should I select if inductance value is not critical?

A: Selection should be based on circuit design requirements and component availability. If the circuit design permits 0.5 µH inductance, the SH-201 is available in higher quantity (1774 pieces versus 907 pieces for SH-101).

Q: Are these parts interchangeable on the PCB?

A: Yes, from a mechanical and electrical interface perspective. Both parts use identical through-hole vertical 4-pin mounting with the same footprint. Substitution is valid only when the inductance difference does not affect circuit performance.
