Engineering Selection Recommendations

Closest Electrical Match: SSHB10H-R05500 provides the nearest inductance value (50 mH versus 49.5 mH nominal) with identical 500 mA current rating and 250V AC voltage specification. This part maintains full ROHS3 compliance and active product status. Height increases from 0.531 inches to 0.610 inches, requiring PCB layout verification.

For Higher Current Applications (600 mA): SSHB10H-R06400 and SSHB21HS-06378 both support 600 mA operation with acceptable inductance ranges (40 mH and 37.8 mH respectively). Both maintain 250V AC rating and -25°C to 120°C operating range. SSHB10H-R06400 offers lower DCR (1.3 Ohm) compared to the original 1.6 Ohm specification.

For Extended Temperature Range: SSHB10H-05212 extends the upper operating temperature to 130°C while maintaining 500 mA current rating. Inductance reduces to 21.2 mH, suitable for applications requiring lower inductance with enhanced thermal performance.

For Higher Inductance Requirements: SSHB21H-R06825 and SSHB21HS-R05910 provide inductance values of 82.5 mH and 91 mH respectively, supporting applications requiring increased filtering at the cost of larger physical dimensions and higher DCR values.

All recommended substitutes maintain ROHS3 compliance, REACH unaffected status, and active manufacturing status. Selection depends on specific application requirements for inductance, current capacity, and physical constraints.

Frequently Asked Questions (FAQ)

Q: Can SSHB10H-R05500 directly replace SSR10HS-05495 in my circuit?

A: SSHB10H-R05500 is electrically compatible with inductance of 50 mH (versus 49.5 mH), identical 500 mA current rating, and matching 250V AC voltage specification. The primary difference is increased height from 0.531 inches to 0.610 inches. PCB layout must accommodate the larger vertical dimension. Both parts operate across -25°C to 120°C and maintain ROHS3 compliance.

Q: What is the difference between SSHB10H and SSHB10HS series?

A: Both series are 2-line through-hole common mode chokes with identical mounting configuration. The SSHB10HS series typically features lower DCR values (1.55 Ohm maximum) compared to SSHB10H series (1.7 Ohm maximum), resulting in reduced power dissipation. Physical dimensions remain consistent at 0.866 inches L x 0.669 inches W x 0.610 inches H.

Q: Can I use a 600 mA rated part in place of a 500 mA rated part?

A: Yes. A higher current rating indicates the component can safely handle greater current without exceeding thermal or electrical limits. SSHB10H-R06400 (600 mA) and SSHB21HS-06378 (600 mA) are suitable replacements for 500 mA applications. Verify that inductance and DCR values meet circuit requirements.

Q: How do I select between SSHB21H and SSHB10H series?

A: SSHB21H series components feature larger physical dimensions (1.024 inches L x 0.906 inches W) compared to SSHB10H series (0.866 inches L x 0.669 inches W). Selection depends on available PCB space and inductance requirements. Both series maintain identical height (0.610 inches) and mounting configuration.

Q: Are all listed substitutes ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH unaffected status, matching the compliance profile of SSR10HS-05495. All parts are active in production with current inventory availability.

Q: What does DCR (DC Resistance) affect in my application?

A: DC Resistance determines power dissipation at rated current. Lower DCR values reduce heat generation. SSR10HS-05495 specifies 1.6 Ohm maximum DCR. SSHB10H-R06400 offers 1.3 Ohm (lower dissipation), while SSHB21HS-R05910 specifies 1.88 Ohm (higher dissipation). Select based on thermal budget and power efficiency requirements.

Q: Can I use SSHB21HS-R05910 (91 mH) instead of SSR10HS-05495 (49.5 mH)?

A: SSHB21HS-R05910 provides nearly double the inductance with identical 500 mA current rating and 250V AC voltage. This substitution is valid only if your circuit design requires higher inductance filtering. Verify that the larger physical dimensions (1.024 inches L x 0.906 inches W) fit your PCB layout. Higher DCR (1.88 Ohm) increases power dissipation.
