Key Parameters

Substitute Part Grouping Explanation

Substitution of the 70F152AI-RC is based on the following critical parameters:

• Inductance Value: 15 mH (primary functional requirement)
• Mounting Type: Through Hole Axial (mechanical compatibility)
• Shielding Configuration: Unshielded (electromagnetic environment match)
• Current Rating: Minimum 47 mA (electrical load capacity)
• DC Resistance: Lower values preferred to reduce power dissipation
• Operating Temperature Range: Must support application requirements
• RoHS Compliance: ROHS3 Compliant status maintained

The AIAP-02-153K from Abracon LLC meets the core inductance and mounting requirements while offering improved current handling (100 mA) and reduced DC resistance (42.5 Ohm), making it suitable for applications where the original part is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The AIAP-02-153K is an active product with ROHS3 compliance, providing design continuity for applications currently using the obsolete 70F152AI-RC. Both components share identical inductance values and unshielded axial configurations, ensuring mechanical and electromagnetic compatibility.

The substitute part offers superior electrical performance with 100 mA current rating versus 47 mA, and significantly lower DC resistance (42.5 Ohm versus 113 Ohm), reducing power dissipation in the inductor. The inductance tolerance widens from ±5% to ±10%, which must be evaluated against circuit requirements.

Operating temperature range differs: the original supports -55°C to 105°C while the substitute operates -40°C to 85°C. Applications requiring the full original temperature range must assess whether the reduced range is acceptable for their thermal environment.

Frequently Asked Questions (FAQ)

Q: Can AIAP-02-153K directly replace 70F152AI-RC in existing designs?

A: Both components share 15 mH inductance, unshielded configuration, and through-hole axial mounting. The substitute accommodates higher current (100 mA versus 47 mA) and exhibits lower DC resistance. Verify that the operating temperature range (-40°C to 85°C) meets application requirements, as it is narrower than the original (-55°C to 105°C).

Q: What are the physical dimension differences?

A: 70F152AI-RC measures 0.300" diameter × 0.500" length (7.62mm × 12.70mm). AIAP-02-153K measures 0.252" diameter × 0.551" length (6.40mm × 14.00mm). Both are axial through-hole components; verify PCB layout compatibility before substitution.

Q: How does the inductance tolerance affect circuit performance?

A: The original part specifies ±5% tolerance while the substitute allows ±10%. For circuits sensitive to inductance variation, measure the impact of this wider tolerance on frequency response, impedance matching, or filtering characteristics.

Q: Are both parts RoHS compliant?

A: Yes, both 70F152AI-RC and AIAP-02-153K are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: What is the advantage of the lower DC resistance in the substitute?

A: The AIAP-02-153K's 42.5 Ohm DCR versus 113 Ohm in the original reduces resistive losses and heat generation, improving efficiency in applications carrying sustained current loads.
