ASPI-0704S-151M-T Equivalent & Substitute Parts

Part Overview

The ASPI-0704S-151M-T is a 150 µH shielded drum core wirewound inductor manufactured by Abracon LLC, rated for 460 mA continuous current with 880mOhm DC resistance. This surface mount component operates across the -40°C to 125°C temperature range and is designed for applications requiring compact, shielded inductive filtering in standard PCB layouts. The part maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance can be maintained across critical operating parameters while accommodating minor variations in test frequency and maximum operating temperature specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0704S-151M-T is determined by strict equivalence across the following critical parameters:

• Inductance Value: 150 µH (±20% tolerance)
• Current Rating: 460 mA minimum
• DC Resistance: 880 mOhm maximum
• Core Material: Ferrite
• Shielding: Shielded construction
• Mounting: Surface mount, nonstandard package
• Physical Footprint: 7.30 × 7.30 × 4.50 mm (identical dimensions)
• Compliance: ROHS3 compliant, MSL 1 rating

The CDRH74NP-151MC-B from Sumida America Components Inc. meets all electrical and mechanical substitution criteria. Minor variations in inductance test frequency (100 kHz vs. 1 kHz) and maximum operating temperature (-40°C to 100°C vs. -40°C to 125°C) do not affect functional equivalence for standard filtering applications within the specified current and temperature operating window.

Parameter Comparison

Engineering Selection Recommendations

Both the ASPI-0704S-151M-T and CDRH74NP-151MC-B are Active products with full ROHS3 compliance and unlimited moisture sensitivity ratings, making either suitable for production deployment. Selection between these parts should be based on:

ASPI-0704S-151M-T (Abracon): Preferred for applications requiring operation across the full -40°C to 125°C temperature range, particularly in high-temperature environments approaching 125°C.

CDRH74NP-151MC-B (Sumida): Suitable for applications operating within -40°C to 100°C. Current inventory availability (5907 pcs) may support shorter lead times compared to the primary part.

Both parts share identical electrical specifications, physical footprint, and compliance certifications. The substitution is mechanically and electrically transparent for standard filtering applications within the overlapping temperature range (-40°C to 100°C).

Frequently Asked Questions (FAQ)

Q: Can CDRH74NP-151MC-B replace ASPI-0704S-151M-T in all applications?

A: Yes, for applications operating within -40°C to 100°C. If your circuit requires sustained operation above 100°C, the ASPI-0704S-151M-T is required.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 7.30 × 7.30 × 4.50 mm and use identical surface mount nonstandard packages. PCB footprints are interchangeable.

Q: Do the inductance test frequencies affect circuit performance?

A: The ASPI-0704S-151M-T is tested at 100 kHz while the CDRH74NP-151MC-B is tested at 1 kHz. Both deliver 150 µH ±20% inductance across standard operating frequencies. For applications requiring specific frequency response characteristics, consult detailed impedance curves from the respective manufacturers.

Q: Are both parts RoHS compliant?

A: Yes. Both the ASPI-0704S-151M-T and CDRH74NP-151MC-B are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity ratings.

Q: What is the DC resistance specification?

A: Both parts specify 880 mOhm maximum DC resistance, ensuring equivalent power dissipation and thermal performance in filtering circuits.
