Engineering Selection Recommendations

Closest Electrical Equivalents:

The SSHB10HS-R07230 and SSR10HS-07265 represent the primary substitute options for the SSRH7H-M06237. Both parts maintain the required 2-line through-hole configuration, 250V AC voltage rating, and ROHS3 compliance. The SSHB10HS-R07230 delivers 23 mH inductance with 810 mOhm DCR, while the SSR10HS-07265 provides 26.5 mH inductance with 850 mOhm DCR. Both support 700 mA current capacity, exceeding the original 600 mA specification.

Secondary Substitution Options:

The SSR21NH-06500 and SSR21NHS-06385 maintain identical current rating (600 mA) and DCR specifications (760 mOhm and 710 mOhm respectively) as the SSRH7H-M06237, with higher inductance values of 50 mH and 38.5 mH. These parts are suitable for applications requiring increased inductance filtering while preserving the original current capacity.

Dimensional Considerations:

The SSRH7H-M06237 features a compact height of 12.00 mm. Substitute parts SSHB10HS-R07230 and SSHB10H-07120 present increased heights of 15.50 mm, while SSR10V-07330, SSR21NV-06500, and SSR21NVS-06385 exceed 21.00 mm. PCB layout constraints must be evaluated before selection.

Compliance Status:

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original component specification.

Frequently Asked Questions (FAQ)

Q: Can SSHB10HS-R07230 directly replace SSRH7H-M06237 in my circuit?

A: The SSHB10HS-R07230 meets all primary substitution criteria: 2-line configuration, through-hole mounting, vertical 4-pin package, 250V AC rating, and ROHS3 compliance. The inductance value of 23 mH falls within the acceptable range (23.0–26.5 mH), and the 700 mA current rating exceeds the original 600 mA specification. However, the increased height of 15.50 mm versus 12.00 mm requires PCB layout verification.

Q: What is the difference between SSR10HS-07265 and SSHB10HS-R07230?

A: Both parts share identical electrical specifications (2-line, through-hole, 250V AC, ROHS3 compliant). The SSR10HS-07265 provides 26.5 mH inductance with 850 mOhm DCR and 13.50 mm height. The SSHB10HS-R07230 delivers 23 mH inductance with 810 mOhm DCR and 15.50 mm height. Selection depends on inductance requirements and available PCB vertical clearance.

Q: Why do some substitute parts have 700 mA rating while the original is 600 mA?

A: Higher current ratings indicate increased thermal capacity and design margin. Parts rated for 700 mA can safely operate at 600 mA with reduced thermal stress. This provides additional design flexibility without compromising circuit performance.

Q: Are SSR21NH-06500 and SSR21NV-06500 interchangeable?

A: Both parts deliver identical electrical performance: 50 mH inductance, 600 mA current rating, 760 mOhm DCR, and ROHS3 compliance. The primary difference is physical height: SSR21NH-06500 measures 14.50 mm while SSR21NV-06500 measures 27.00 mm. Selection is determined by available PCB space.

Q: Can I use SSHB10H-07120 as a substitute despite its lower inductance value?

A: The SSHB10H-07120 provides only 12 mH inductance, significantly below the original 23.7 mH specification. This part is not recommended as a direct substitute unless circuit analysis confirms that reduced inductance filtering is acceptable for the application. The higher current rating (700 mA) and extended temperature range (-25°C to 130°C) do not compensate for the inductance reduction.

Q: What packaging considerations apply when switching from SSRH7H-M06237 to substitute parts?

A: All substitute parts maintain the through-hole vertical 4-pin configuration, ensuring footprint compatibility. However, height variations range from 12.00 mm to 27.00 mm. Verify PCB clearance above the component mounting surface before finalizing part selection. Dimensional drawings should be consulted for precise spatial requirements.
