Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLC6045T-150M is determined by the following critical parameters:

• Inductance Value: Must be 15 µH with ±20% tolerance
• Current Rating: Minimum 2.1 A continuous current capability
• Saturation Current (Isat): Must support 2.1 A without saturation
• DC Resistance: Lower or equivalent to 91 mOhm to maintain circuit performance
• Shielding: Must be shielded to preserve electromagnetic isolation
• Package Footprint: Surface mount configuration with 6.00mm × 6.00mm base dimensions and 4.50mm maximum height
• Moisture Sensitivity: MSL 1 classification required
• Operating Temperature: Must support -40°C minimum; extended upper range acceptable

The ASPI-6045S-150M-T from Abracon LLC meets all substitution criteria. This part maintains identical inductance, tolerance, and physical footprint while offering improved DC resistance (68 mOhm versus 91 mOhm) and extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 105°C).

Engineering Selection Recommendations

The ASPI-6045S-150M-T is a direct functional substitute for the obsolete VLC6045T-150M. Selection should be based on the following factors:

Product Status: The VLC6045T-150M is obsolete. The ASPI-6045S-150M-T carries active product status from Abracon LLC, ensuring ongoing availability and manufacturing support.

Compliance & Certifications: The ASPI-6045S-150M-T is RoHS3 compliant, providing enhanced environmental compliance compared to the original part. Both components are REACH unaffected and classified under ECCN EAR99.

Performance Advantages: The substitute part delivers lower DC resistance (68 mOhm versus 91 mOhm), reducing power dissipation and heat generation in the circuit. The higher saturation current rating (2.5 A versus 2.1 A) provides additional design margin. Extended operating temperature range (-40°C ~ 125°C) supports broader application environments.

Packaging & Handling: Both parts share identical surface mount footprint and MSL 1 moisture sensitivity classification. The substitute is supplied in Tape & Reel packaging, standard for production environments.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-6045S-150M-T be used as a direct replacement for the VLC6045T-150M on existing PCBs?

A: Yes. Both parts share identical package dimensions (6.00mm × 6.00mm × 4.50mm maximum height) and surface mount configuration. No PCB layout modifications are required.

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

A: The ASPI-6045S-150M-T exhibits 68 mOhm DC resistance compared to 91 mOhm in the original part. This 25% reduction decreases resistive losses, lowering power dissipation and operating temperature of the inductor during current flow.

Q: Are there any temperature-related limitations when substituting?

A: No. The substitute part supports an extended operating temperature range (-40°C ~ 125°C) compared to the original (-40°C ~ 105°C). Applications operating within the original temperature window face no thermal constraints.

Q: How do the saturation current ratings compare?

A: The ASPI-6045S-150M-T has a saturation current of 2.5 A versus 2.1 A for the VLC6045T-150M. Both parts support the required 2.1 A continuous current rating. The higher saturation rating in the substitute provides additional margin before inductance degradation occurs.

Q: What packaging format is the substitute available in?

A: The ASPI-6045S-150M-T is supplied in Tape & Reel (TR) format, standard for automated assembly and production environments. The original part packaging format was not specified in available data.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both parts carry MSL 1 (Unlimited) classification, indicating no moisture-related handling restrictions or baking requirements prior to soldering.

Q: Does the substitute part provide self-resonant frequency data?

A: Yes. The ASPI-6045S-150M-T specifies a self-resonant frequency of 12 MHz. This parameter was not provided for the original VLC6045T-150M and may be useful for high-frequency circuit analysis.
