Substitute Part Grouping Explanation

Substitute parts for the SSHB21HS-20034 are selected based on the following criteria:

Primary Substitution Parameters:

• Number of Lines: 2 (all substitutes maintain this requirement)
• Mounting Type: Through Hole (all substitutes use through-hole mounting)
• Package / Case: Vertical, 4 PC Pin (all substitutes use this configuration)
• Voltage Rating - AC: 250V (all substitutes maintain this rating)
• RoHS Status: ROHS3 Compliant (all substitutes meet this compliance requirement)

Secondary Variation Parameters:

• Inductance @ 10 kHz: Range from 1.4 mH to 12.5 mH
• Current Rating (Max): Range from 2A to 2.2A
• DC Resistance (Max): Range from 120 mOhm to 160 mOhm
• Operating Temperature Range: -25°C ~ 120°C or -25°C ~ 130°C
• Physical Dimensions: Variations in length, width, and height

Substitution is valid when the application requirements permit operation within the specified inductance, current, and resistance ranges of the alternative part.

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. Selection among substitute parts depends on specific application requirements:

SSHB10H-22014: Suitable for applications requiring lower inductance (1.4 mH) with higher current capacity (2.2A) and lower DC resistance (120 mOhm). Offers extended operating temperature range to 130°C. Smaller physical footprint (22.00mm x 17.00mm).

SSHB10H-R22034: Provides inductance (3.4 mH) closely matching the main part with higher current capacity (2.2A) and lower DC resistance (120 mOhm). Maintains identical operating temperature range. Smaller physical footprint (22.00mm x 17.00mm).

SSR21NHS-M20103: Delivers higher inductance (10.3 mH) with matching current rating (2A) and slightly elevated DC resistance (150 mOhm). Larger physical footprint (23.00mm x 23.00mm) with reduced height (14.50mm).

SSR21NV-M20125: Provides highest inductance (12.5 mH) with matching current rating (2A) and highest DC resistance (160 mOhm). Compact length (22.00mm) with increased height (27.00mm).

SSR21NVS-M20103: Delivers inductance (10.3 mH) matching SSR21NHS-M20103 with identical electrical specifications. Compact length (22.00mm) with increased height (27.00mm).

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the SSHB21HS-20034?

A: Substitute parts must maintain 2-line configuration, through-hole mounting, vertical 4-pin package, 250V AC voltage rating, and ROHS3 compliance. Inductance, current rating, and DC resistance may vary within the specified ranges of available alternatives.

Q: Can I use SSHB10H-22014 as a direct replacement?

A: SSHB10H-22014 is electrically and mechanically compatible for 2-line common mode choke applications. However, its inductance (1.4 mH) differs significantly from the main part (3.431 mH). Use this substitute only if your application permits operation at the lower inductance value.

Q: What is the difference between SSR21NHS-M20103 and SSR21NVS-M20103?

A: Both parts share identical electrical specifications: 10.3 mH inductance, 2A current rating, and 150 mOhm DC resistance. The primary difference is physical dimensions. SSR21NHS-M20103 measures 23.00mm x 23.00mm x 14.50mm height, while SSR21NVS-M20103 measures 22.00mm x 16.00mm x 27.00mm height. Select based on available board space.

Q: Why does SSHB10H-R22034 have a higher current rating than the main part?

A: SSHB10H-R22034 is rated for 2.2A maximum current compared to the main part's 2A rating. This higher rating does not affect substitution compatibility; it indicates the part can safely handle the main part's current requirements with additional margin.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use identical packaging: Vertical, 4 PC Pin through-hole configuration. Physical dimensions vary, which may affect PCB layout considerations. Verify board space availability before selection.

Q: What is the significance of DC resistance differences among substitute parts?

A: DC resistance values range from 120 mOhm to 160 mOhm across substitutes. Lower DC resistance reduces power dissipation and heat generation. Select based on thermal and efficiency requirements of your specific application.

Q: Can I use SSR21NV-M20125 if my circuit requires 3.431 mH inductance?

A: SSR21NV-M20125 provides 12.5 mH inductance, which is significantly higher than the required 3.431 mH. Use this substitute only if your application design permits operation at the higher inductance value.
