Key Parameters

Substitute Part Grouping Explanation

The ASPI-0615FS-330M-T2 qualifies as a direct substitute based on the following critical parameters:

Matching Parameters:

• Inductance value: 33 µH (identical)
• Inductance tolerance: ±20% (identical)
• Core material: Ferrite (identical)
• Shielding: Shielded (identical)
• Mounting type: Surface Mount (identical)
• Package footprint: 6.00 mm x 6.00 mm (identical)
• Inductance test frequency: 100 kHz (identical)
• RoHS compliance: ROHS3 Compliant (identical)
• Moisture sensitivity: 1 (Unlimited) (identical)

Improved Parameters:

• Current rating: 900 mA (versus 550 mA original)
• DC resistance: 310 mOhm (versus 754 mOhm original)
• Current saturation: 900 mA (versus 590 mA original)
• Operating temperature: -25°C ~ 120°C (versus -40°C ~ 105°C original)
• Product status: Active (versus Obsolete original)

The substitute part maintains identical electrical and mechanical specifications while offering superior current handling capability and lower DC resistance, making it suitable for applications requiring the original part's performance envelope.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-0615FS-330M-T2 is the active equivalent for the obsolete ASPI-0612FS-330M-T. Both parts maintain identical inductance specifications, core material, shielding configuration, and footprint dimensions. The substitute part is manufactured by the same supplier and carries equivalent ROHS3 and REACH compliance certifications.

The primary design consideration is the increased seated height of 2.20 mm versus 1.20 mm. Applications with vertical clearance constraints must verify compatibility with the substitute part's physical profile. The improved current rating and reduced DC resistance of the substitute part provide enhanced performance margins for circuits operating near the original part's current limits.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-0615FS-330M-T2 be used as a direct replacement for the ASPI-0612FS-330M-T?

A: Yes, the substitute part maintains identical inductance value, tolerance, core material, shielding, and footprint dimensions. The primary design consideration is the increased height (2.20 mm versus 1.20 mm), which must be verified against PCB clearance requirements.

Q: What are the key differences between these parts?

A: The substitute part offers improved electrical performance with 900 mA current rating versus 550 mA, and 310 mOhm DC resistance versus 754 mOhm. The seated height increases from 1.20 mm to 2.20 mm. Both parts are ROHS3 compliant and use identical ferrite core material.

Q: Does the increased current rating affect circuit behavior?

A: The substitute part's higher current saturation point (900 mA) and lower DC resistance (310 mOhm) do not alter the inductance value or frequency response. These parameters represent improved performance margins and reduced power dissipation in the inductor itself.

Q: Are there packaging differences?

A: The original part is supplied in bulk packaging, while the substitute is supplied in Tape & Reel (TR) format. Both parts are identical in electrical and mechanical specifications.

Q: What is the impact of the different operating temperature ranges?

A: The original part operates from -40°C to 105°C, while the substitute operates from -25°C to 120°C. For applications requiring operation below -25°C, the original specification must be maintained through alternative sourcing or design modification.
