Substitutes are grouped by inductance value to support applications requiring different filtering characteristics while maintaining electrical and mechanical compatibility within the specified parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status with KEMET and are ROHS3 compliant, ensuring long-term availability and regulatory compliance equivalent to the SSHB21H-R12296 main part.

Selection by Inductance Requirement:

• SSHB21H-12145 (14.5 mH): Lower inductance option for applications requiring reduced filtering impedance. Maintains identical DC resistance specification (490 mOhm) and current rating (1.2A).

• SSHB21HS-R12220 (22 mH): Mid-range inductance with improved DC resistance performance (430 mOhm versus 490 mOhm). Suitable for applications where lower insertion loss is beneficial.

• SSR21NH-M12345 (34.5 mH): Higher inductance option for enhanced common mode filtering. Features reduced DC resistance (430 mOhm) and compact footprint (23.00mm x 23.00mm versus 26.00mm x 23.00mm).

• SSRH24NVS-12500 (50 mH): Maximum inductance option for maximum common mode attenuation. Increased height (31.00mm) accommodates higher inductance winding. DC resistance specification (430 mOhm) provides efficient performance.

All substitutes support identical current rating (1.2A), voltage rating (250V AC), operating temperature range (-25°C to 120°C), and through-hole mounting configuration with 4-pin vertical package.

Frequently Asked Questions (FAQ)

Q: Can SSHB21H-12145 replace SSHB21H-R12296 in my application?

A: SSHB21H-12145 is electrically compatible if your circuit design accommodates the lower inductance value (14.5 mH versus 29.6 mH). Both parts share identical current rating (1.2A), voltage rating (250V AC), DC resistance specification (490 mOhm), operating temperature range (-25°C to 120°C), and through-hole mounting configuration. Verify that the reduced inductance meets your filtering requirements.

Q: What is the difference between SSHB21HS-R12220 and SSHB21H-R12296?

A: Both parts operate at different inductance values (22 mH versus 29.6 mH) and belong to different series designations (SSHB21HS versus SSHB21H). SSHB21HS-R12220 features lower DC resistance (430 mOhm versus 490 mOhm), resulting in reduced insertion loss. Physical dimensions and pin configuration remain identical. Selection depends on inductance and insertion loss requirements.

Q: Are all substitute parts physically compatible with the same PCB footprint?

A: SSR21NH-M12345 and SSRH24NVS-12500 have different physical dimensions compared to SSHB21H-R12296. SSR21NH-M12345 has a smaller footprint (23.00mm x 23.00mm versus 26.00mm x 23.00mm). SSRH24NVS-12500 has increased height (31.00mm versus 15.50mm). SSHB21H-12145 and SSHB21HS-R12220 maintain identical dimensions (26.00mm x 23.00mm x 15.50mm). Verify PCB layout compatibility before substitution.

Q: Do all substitute parts maintain the same compliance certifications?

A: All substitute parts are ROHS3 compliant and maintain active product status with KEMET. REACH status is unaffected for all parts. ECCN classification (EAR99) and HTSUS code (8548.00.0000) are identical across all parts.

Q: What inductance value should I select for my common mode filtering application?

A: Inductance selection depends on your target frequency and attenuation requirements. Available options range from 14.5 mH (SSHB21H-12145) to 50 mH (SSRH24NVS-12500). Higher inductance values provide greater common mode attenuation at the expense of increased component size and height. All parts maintain identical current rating (1.2A) and voltage rating (250V AC).

Q: Can I use SSRH24NVS-12500 in a space-constrained application?

A: SSRH24NVS-12500 has a maximum height of 31.00mm, which is significantly larger than SSHB21H-R12296 (15.50mm). For space-constrained applications, SSHB21H-12145, SSHB21HS-R12220, or SSR21NH-M12345 are more suitable options. SSR21NH-M12345 offers the most compact footprint (23.00mm x 23.00mm) while maintaining 34.5 mH inductance.
