Engineering Selection Recommendations

The 9250A-152-RC from Bourns Inc. is the direct equivalent substitute for the obsolete IMS05SH1R5K. Selection of this substitute is based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters are identical, including inductance value, current rating, DC resistance, Q factor, and self-resonant frequency. The substitute maintains the same shielded configuration and frequency response characteristics.

Mechanical Compatibility: Physical dimensions and axial through-hole mounting configuration are identical, ensuring direct board-level compatibility without layout modifications.

Regulatory Compliance: The 9250A-152-RC maintains ROHS3 compliance and REACH unaffected status, matching the original part's regulatory standing. Both components carry EAR99 ECCN classification.

Product Status: The substitute part is active and available, addressing the obsolescence of the original IMS05SH1R5K. Current inventory of 972 pieces is available.

Temperature Performance: The substitute operates across an extended temperature range of -55°C to 125°C, providing additional thermal margin beyond the original part's -55°C to 105°C specification.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-152-RC be used as a direct replacement for the IMS05SH1R5K?

A: Yes. The 9250A-152-RC meets all electrical and mechanical specifications of the IMS05SH1R5K. Inductance, current rating, DC resistance, Q factor, self-resonant frequency, shielding, physical dimensions, and mounting configuration are identical. No circuit modifications or board layout changes are required.

Q: What is the primary difference between these two parts?

A: The IMS05SH1R5K is obsolete, while the 9250A-152-RC is an active product. The substitute also features an extended operating temperature range of -55°C to 125°C compared to the original -55°C to 105°C specification. The core material differs (iron powder versus ferrite), but electrical performance parameters remain equivalent.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Regulatory standing is equivalent.

Q: Will the 9250A-152-RC fit in the same PCB footprint?

A: Yes. Both components share identical physical dimensions of 0.162" diameter by 0.410" length (4.11mm x 10.41mm) and use axial through-hole mounting. No PCB modifications are necessary.

Q: What is the saturation current specification for the substitute?

A: The 9250A-152-RC has a saturation current (Isat) specification of 815 mA, matching the current rating of the original part.

Q: Are there inventory considerations for the substitute part?

A: The 9250A-152-RC is available with 972 pieces in current stock as new original inventory, providing supply continuity for the obsolete IMS05SH1R5K.
