Engineering Selection Recommendations

Same-Footprint Substitutes (SSRH7H-M Series):

The SSRH7HS-M07154, SSRH7H-M06237, and SSRH7H-M07196 maintain identical physical dimensions (18.00 × 14.50 × 12.00 mm) and are direct mechanical replacements. All three parts retain Active product status, ROHS3 compliance, and REACH unaffected designation. Selection among these parts depends on whether the application can accommodate inductance variation (15.4 mH to 23.7 mH) and current rating differences (600 mA to 700 mA). The SSRH7HS-M07154 offers the lowest DCR at 630 mOhm with increased current capacity to 700 mA. The SSRH7H-M06237 provides higher inductance at 23.7 mH while maintaining 600 mA current rating.

Larger-Footprint Substitutes (SSHB10HS Series):

The SSHB10HS-07099 and SSHB10HS-R07230 require additional board space (22.00 × 17.00 × 15.50 mm) but offer 700 mA current capacity. The SSHB10HS-R07230 provides 23 mH inductance comparable to the main part while supporting higher current. Both maintain Active status and full compliance certifications.

Larger-Footprint Substitutes (SSR21NH and SSR21NV Series):

The SSR21NH-06500 and SSR21NHS-06385 occupy a larger square footprint (23.00 × 23.00 mm) and deliver significantly higher inductance values (38.5 mH to 50 mH) at 600 mA current rating. The SSR21NV series variants provide similar inductance with alternative dimensions (22.00 × 16.00 mm) and increased height (27.00 mm). All SSR series parts maintain Active status and required compliance certifications.

All substitute parts are manufactured by KEMET, maintain 250V AC voltage rating, operate across -25°C to 120°C temperature range, and comply with ROHS3 and REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can SSRH7HS-M07154 replace SSRH7HS-M06185 in a space-constrained application?

A: Yes. Both parts share identical physical dimensions (18.00 × 14.50 × 12.00 mm) and mounting configuration. The SSRH7HS-M07154 provides lower inductance (15.4 mH versus 18.5 mH) and lower DCR (630 mOhm versus 690 mOhm), with increased current capacity (700 mA versus 600 mA). Substitution is mechanically and electrically compatible if the application circuit tolerates the inductance reduction.

Q: What is the primary difference between SSRH7H-M and SSHB10HS series substitutes?

A: The SSRH7H-M series maintains the compact 18.00 × 14.50 mm footprint of the original part. The SSHB10HS series requires larger board space (22.00 × 17.00 mm) but provides 700 mA current capacity versus 600 mA. Selection depends on available PCB area and current requirements.

Q: Are SSR21NH and SSR21NV series parts suitable for applications requiring 18.5 mH inductance?

A: No. The SSR21NH and SSR21NV series deliver significantly higher inductance values (38.5 mH to 50 mH). These parts are suitable only when the application circuit design permits or requires higher inductance. They occupy larger physical footprints and are not direct mechanical replacements.

Q: Do all substitute parts maintain the same voltage and temperature ratings?

A: Yes. All substitute parts listed maintain 250V AC voltage rating and operate across the -25°C to 120°C temperature range. All are ROHS3 compliant and REACH unaffected, matching the original part's compliance status.

Q: Which substitute offers the lowest DC resistance?

A: The SSRH7HS-M07154 provides the lowest DCR at 630 mOhm maximum, compared to 690 mOhm for the original SSRH7HS-M06185. This lower resistance reduces power dissipation in applications operating at or near the 700 mA current rating.

Q: Can I use a substitute with higher current rating in a 600 mA application?

A: Yes. Parts rated for 700 mA current (SSRH7HS-M07154, SSRH7H-M07196, SSHB10HS-07099, SSHB10HS-R07230) are electrically compatible with 600 mA applications. The higher current rating provides design margin and does not create compatibility issues.

Q: What inventory availability should I consider when selecting a substitute?

A: Current inventory levels are provided in the parameter comparison table. The SSRH7HS-M07154 offers the highest availability at 1687 pieces, while the SSHB10HS-R07230 has the lowest at 931 pieces. Inventory status may change; verify current availability with the supplier.
