Engineering Selection Recommendations

Footprint-Compatible Substitutes (Same PCB Mounting Hole Pattern):

Parts SSHB21H-04610, SSHB21H-R041250, and SSHB21HS-R041050 share identical footprint dimensions (26.00 mm × 23.00 mm × 15.50 mm height) with the SSHB21HS-04507. These parts are direct mechanical replacements on existing PCB layouts. Selection among these three depends on required inductance value: 61 mH (SSHB21H-04610), 105 mH (SSHB21HS-R041050), or 125 mH (SSHB21H-R041250). All maintain 400 mA current rating, 250 V AC voltage rating, and RoHS3 compliance.

Alternative Footprint Substitutes (Different PCB Mounting Requirements):

Parts SSR21NH-M041500, SSR21NV-M041500, SSR21NVS-041090, and SSRH7HS-M04467 provide electrical equivalence but require PCB layout modification due to different dimensional specifications. These parts are suitable when PCB redesign is acceptable or when space constraints favor compact form factors. The SSRH7HS-M04467 offers the smallest footprint (18.00 mm × 14.50 mm × 12.00 mm) with inductance of 46.7 mH. The SSR21NVS-041090 provides 109 mH inductance with lowest DCR (1.8 Ohm) in a 22.00 mm × 16.00 mm × 27.00 mm package.

Compliance and Product Status:

All substitute parts maintain Active product status, RoHS3 compliance, REACH unaffected designation, and identical operating temperature range (-25°C to 120°C). No additional qualification or testing documentation is required beyond standard component acceptance procedures.

Frequently Asked Questions (FAQ)

Q: Can SSHB21H-04610 replace SSHB21HS-04507 on the same PCB without layout changes?

A: Yes. Both parts share identical footprint dimensions (26.00 mm × 23.00 mm × 15.50 mm height) and mounting configuration (Vertical, 4 PC Pin through-hole). The primary difference is inductance value: 61 mH versus 50.7 mH. Substitution is mechanically compatible; circuit performance depends on whether the higher inductance value is acceptable for the application.

Q: What is the difference between SSHB21HS and SSHB21H series parts?

A: Both series share identical footprints and electrical ratings (400 mA, 250 V AC, -25°C to 120°C). The primary distinction is DC resistance: SSHB21HS parts (SSHB21HS-04507, SSHB21HS-R041050) specify 2.03 Ohm maximum DCR, while SSHB21H parts (SSHB21H-04610, SSHB21H-R041250) specify 2.25 Ohm maximum DCR. Selection depends on thermal dissipation requirements in the target application.

Q: Are SSR series parts (SSR21NH-M041500, SSR21NV-M041500, SSR21NVS-041090) direct replacements?

A: SSR series parts are electrical equivalents but not direct mechanical replacements. They maintain identical current rating (400 mA), voltage rating (250 V AC), and operating temperature range (-25°C to 120°C), but feature different footprint dimensions. PCB layout modification is required. SSR21NH-M041500 and SSR21NV-M041500 both provide 150 mH inductance; SSR21NVS-041090 provides 109 mH inductance with the lowest DCR (1.8 Ohm).

Q: Which substitute part has the lowest DC resistance?

A: SSRH7HS-M04467 specifies the lowest maximum DCR at 1.79 Ohm, followed by SSR21NVS-041090 at 1.8 Ohm. Both are suitable when minimizing resistive losses is a design priority. However, SSRH7HS-M04467 provides only 46.7 mH inductance, which is lower than the original 50.7 mH specification.

Q: Can I use SSR21NV-M041500 if my PCB has space constraints?

A: SSR21NV-M041500 is not suitable for space-constrained applications. It measures 22.00 mm × 16.00 mm × 27.00 mm (height), making it taller than the original SSHB21HS-04507 (26.00 mm × 23.00 mm × 15.50 mm). For compact installations, SSRH7HS-M04467 (18.00 mm × 14.50 mm × 12.00 mm) is the smallest available substitute.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain RoHS3 compliance and REACH unaffected status, identical to the SSHB21HS-04507. No additional environmental or regulatory qualification is required.

Q: What inductance range is acceptable for substitution?

A: Substitute parts span 46.7 mH to 150 mH at 10 kHz. Selection within this range depends on circuit requirements. The original SSHB21HS-04507 specifies 50.7 mH; parts within ±10% (45.6 mH to 55.8 mH) are closest electrical matches. Parts outside this range (SSHB21H-04610 at 61 mH, SSHB21HS-R041050 at 105 mH, and higher) require circuit analysis to confirm performance compatibility.
