Engineering Selection Recommendations

SSRH7H-M17029 Selection Criteria: This substitute provides higher inductance (2.9 mH vs. 2.3 mH) with identical current rating (1.7A) and slightly elevated DC resistance (120 mOhm vs. 100 mOhm). Selection is appropriate for applications requiring increased inductance filtering at the cost of marginally higher resistive losses. All compliance certifications and physical parameters remain identical.

SSRH7HS-M20013 Selection Criteria: This substitute provides lower inductance (1.3 mH vs. 2.3 mH) with higher current capacity (2.0A vs. 1.7A) and lower DC resistance (80 mOhm vs. 100 mOhm). Selection is appropriate for applications requiring higher current handling and reduced power dissipation, with the trade-off of reduced inductance filtering. All compliance certifications and physical parameters remain identical.

Both substitutes maintain ROHS3 compliance, REACH unaffected status, and active product status. All three parts are manufactured by KEMET within the SSRH7H-M series and share identical mechanical packaging.

Frequently Asked Questions (FAQ)

Q: Can SSRH7H-M17029 be used as a direct replacement for SSRH7HS-M17023?

A: SSRH7H-M17029 is mechanically and electrically compatible for through-hole PCB mounting. The higher inductance value (2.9 mH vs. 2.3 mH) and slightly higher DC resistance (120 mOhm vs. 100 mOhm) must be evaluated against circuit requirements. Both parts share identical current rating, voltage rating, temperature range, and compliance certifications.

Q: Can SSRH7HS-M20013 be used as a direct replacement for SSRH7HS-M17023?

A: SSRH7HS-M20013 is mechanically and electrically compatible for through-hole PCB mounting. The lower inductance value (1.3 mH vs. 2.3 mH) and higher current capacity (2.0A vs. 1.7A) with lower DC resistance (80 mOhm vs. 100 mOhm) must be evaluated against circuit requirements. Both parts share identical voltage rating, temperature range, and compliance certifications.

Q: Do all three parts have identical physical dimensions?

A: Yes. SSRH7HS-M17023, SSRH7H-M17029, and SSRH7HS-M20013 all measure 18.00mm L x 14.50mm W x 12.00mm H with vertical 4-pin through-hole mounting. They are mechanically interchangeable on PCBs designed for this form factor.

Q: What is the primary difference between the substitute parts?

A: SSRH7H-M17029 prioritizes inductance filtering with higher inductance and identical current rating. SSRH7HS-M20013 prioritizes current capacity and efficiency with lower inductance, higher current rating, and lower DC resistance. Selection depends on whether the circuit requires higher inductance filtering or higher current handling.

Q: Are all three parts compliant with environmental regulations?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected. All maintain active product status with KEMET as the manufacturer.

Q: What is the AC voltage rating for all substitute parts?

A: All three parts are rated for 250V AC. Operating temperature range is -25°C to 120°C across all variants.
