SSHB21HS-R30028 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The SSHB21HS-R30028 is a 2.8 mH Common Mode Choke (CMC) manufactured by KEMET, designed for two-line filtering applications in through-hole configurations. This component operates at 3A maximum current with 60 mOhm DC resistance 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, matching current ratings, and identical mechanical mounting specifications. Alternative models provide design flexibility for component availability, inventory optimization, and application-specific space constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSHB21HS-R30028 is determined by the following criteria:

Primary Matching Parameters:

• Number of Lines: 2 (fixed requirement)
• Current Rating (Max): 3A (fixed requirement)
• DC Resistance (Max): 60 mOhm (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 Parameter:

• Inductance @ 10 kHz: Substitutes may differ from 2.8 mH while maintaining electrical compatibility within the application circuit design

All identified substitute parts maintain identical electrical ratings, thermal specifications, compliance certifications, and mechanical mounting configurations. Variations in inductance value and physical dimensions are the only differentiating factors among substitute options.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status with ROHS3 compliance and REACH unaffected certification. Selection among equivalent options is based on:

Inductance Value Requirements: The main part SSHB21HS-R30028 operates at 2.8 mH. Substitute parts offer inductance values of 600 µH, 1.3 mH, and 1.5 mH. Circuit design specifications determine which inductance value is acceptable for the application.

Series Compatibility: SSHB10HS and SSHB21HS series parts share identical electrical and thermal ratings. SSR series parts (SSR10HS-30013 and SSR10VS-30013) provide equivalent electrical performance with alternative mechanical packaging.

Physical Dimensions: SSHB21HS-R30028 measures 26.00mm L × 23.00mm W × 15.50mm H. SSHB10HS variants measure 22.00mm L × 17.00mm W × 15.50mm H. SSR10HS-30013 measures 15.50mm maximum height. SSR10VS-30013 measures 23.50mm L × 13.00mm W × 21.00mm H. Space constraints within the target application determine dimensional compatibility.

Inventory Availability: All substitute parts maintain active stock status with quantities ranging from 934 to 1547 pieces.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must remain constant when selecting a substitute for SSHB21HS-R30028?

A: Current rating (3A), DC resistance (60 mOhm), AC voltage rating (250V), operating temperature range (-25°C to 120°C), number of lines (2), and mounting type (through hole) must remain unchanged. These parameters define the electrical and thermal operating envelope.

Q: Can inductance value be changed when substituting this component?

A: Inductance value variation is permitted only when the application circuit design accommodates the alternative inductance specification. The substitute parts provide 600 µH, 1.3 mH, and 1.5 mH options. Circuit performance validation is required to confirm compatibility with the specific application.

Q: What is the difference between SSHB21HS and SSR series parts?

A: Both series maintain identical electrical ratings (3A, 60 mOhm, 250V, -25°C to 120°C). The primary differences are series designation and physical dimensions. SSHB21HS parts measure 26.00mm × 23.00mm. SSR10HS-30013 has a maximum height of 13.50mm. SSR10VS-30013 measures 23.50mm × 13.00mm × 21.00mm.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected certification status, matching the compliance profile of SSHB21HS-R30028.

Q: How do physical dimensions affect part selection?

A: Physical dimensions determine whether a substitute part fits within the available PCB space. SSHB10HS variants are smaller (22.00mm × 17.00mm) compared to SSHB21HS-R30028 (26.00mm × 23.00mm). SSR10VS-30013 has increased height (21.00mm) compared to the main part (15.50mm). Verify available space before final selection.

Q: Can SSHB10HS-30006 (600 µH) replace SSHB21HS-R30028 (2.8 mH)?

A: Substitution is possible only if the application circuit design functions with 600 µH inductance. The significantly lower inductance value alters filtering characteristics and must be validated for the specific application requirements.

Q: What inventory quantities are available for each substitute?

A: SSHB10HS-30006: 1379 pieces; SSHB10HS-R30015: 934 pieces; SSHB21HS-30013: 1088 pieces; SSR10HS-30013: 973 pieces; SSR10VS-30013: 1547 pieces.
