SSHB21H-07340 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The SSHB21H-07340 is a 34 mH Common Mode Choke (CMC) manufactured by KEMET, designed for two-line filtering applications in through-hole configurations. This component operates at 700mA maximum current with a DC resistance of 1.16Ohm and is rated for 250V AC operation across an operating temperature range of -25°C to 120°C. The part maintains Active product status and is ROHS3 compliant.

Substitute parts are identified when equivalent electrical performance can be achieved through alternative inductance values, DC resistance specifications, or dimensional variations while maintaining core functional parameters such as current rating, voltage rating, temperature range, and mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSHB21H-07340 is determined by the following critical parameters:

Core Compatibility Criteria:

• Number of Lines: 2 (fixed requirement)
• Current Rating (Max): 700mA (fixed requirement)
• Voltage Rating - AC: 250V (fixed requirement)
• Operating Temperature: -25°C ~ 120°C (fixed requirement)
• Mounting Type: Through Hole (fixed requirement)
• Package / Case: Vertical, 4 PC Pin (fixed requirement)
• RoHS Status: ROHS3 Compliant (fixed requirement)

Variable Parameters Allowing Substitution:

• Inductance @ 10 kHz: 26.7 mH to 89 mH range
• DC Resistance (Max): 1.03Ohm to 1.16Ohm range
• Size / Dimension: 0.906" L x 0.906" W (23.00mm x 23.00mm) to 1.024" L x 0.906" W (26.00mm x 23.00mm)
• Height (Max): 0.571" (14.50mm) to 0.610" (15.50mm)

All identified substitute parts maintain the fixed parameters while offering alternative inductance and resistance characteristics within the KEMET common mode choke product family.

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original SSHB21H-07340 component. Selection between the main part and substitutes depends on application-specific inductance requirements:

SSHB21H-R07700 provides double the inductance (70 mH) while maintaining identical DC resistance and dimensional specifications. This part is suitable for applications requiring higher filtering impedance at the same current and voltage ratings.

SSHB21HS-07267 offers lower inductance (26.7 mH) with reduced DC resistance (1.03Ohm). This configuration is applicable where lower insertion loss is prioritized and inductance requirements are less stringent than the main part.

SSR21NH-M07890 delivers the highest inductance value (89 mH) with a compact footprint (23.00mm x 23.00mm length and width, 14.50mm height). This part accommodates space-constrained layouts while providing maximum filtering capability within the 700mA current specification.

All parts share identical electrical ratings (250V AC, 700mA, -25°C to 120°C operating range) and mounting configuration (through-hole, vertical 4-pin package), confirming functional interchangeability within their respective inductance specifications.

Frequently Asked Questions (FAQ)

Q: What determines whether a part can substitute for the SSHB21H-07340?

A: Substitute parts must maintain identical specifications for number of lines (2), current rating (700mA), voltage rating (250V AC), operating temperature range (-25°C to 120°C), mounting type (through-hole), package configuration (vertical 4-pin), and compliance status (ROHS3). Inductance values, DC resistance, and physical dimensions may vary within the defined ranges.

Q: Can SSHB21H-R07700 be used in place of SSHB21H-07340?

A: SSHB21H-R07700 is electrically compatible with SSHB21H-07340 for all core parameters. The primary difference is inductance: 70 mH versus 34 mH. Selection depends on whether the application requires the higher inductance value. Both parts share identical dimensions and DC resistance specifications.

Q: What is the advantage of SSHB21HS-07267 over the main part?

A: SSHB21HS-07267 provides lower DC resistance (1.03Ohm versus 1.16Ohm), resulting in reduced power dissipation and insertion loss. Inductance is lower at 26.7 mH. This part is suitable for applications where minimizing resistive losses is critical and inductance requirements are lower than the main part specification.

Q: Why does SSR21NH-M07890 have different dimensions?

A: SSR21NH-M07890 belongs to the SSR series rather than the SSHB21H series, resulting in a more compact footprint (23.00mm x 23.00mm versus 26.00mm x 23.00mm) and reduced height (14.50mm versus 15.50mm). All electrical parameters remain compatible. This part accommodates space-constrained PCB layouts.

Q: Are all substitute parts in stock?

A: Inventory availability is as follows: SSHB21H-07340 (694 Pcs), SSHB21H-R07700 (890 Pcs), SSHB21HS-07267 (1005 Pcs), SSR21NH-M07890 (1362 Pcs). All parts are listed as new original stock.

Q: Do all parts meet the same compliance requirements?

A: All parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Compliance status is uniform across the main part and all substitutes.
