Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASPI-6045T-102M-T is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 1 mH (±20% tolerance)
• Shielding requirement: Shielded construction
• Core material: Ferrite
• Mounting type: Surface mount
• Operating temperature range: -40°C to 125°C minimum
• Inductance test frequency: 100 kHz

Secondary Compatibility Factors:

• Current rating must equal or exceed 300 mA
• DC resistance must be compatible with circuit design requirements
• RoHS3 compliance required for regulatory alignment

The substitute part CDRH127L125NP-102MC satisfies all primary matching criteria. While this substitute employs drum core construction rather than wirewound design, both configurations deliver equivalent inductance performance at the specified test frequency and operating conditions. The substitute part provides superior current handling capability (640 mA) and lower DC resistance (1.495 Ohm), making it suitable for applications where the original part is no longer available.

Engineering Selection Recommendations

CDRH127L125NP-102MC as Primary Substitute:

The CDRH127L125NP-102MC is the active equivalent for the obsolete ASPI-6045T-102M-T. Both components meet identical inductance specifications (1 mH ±20%), operate across the same temperature range (-40°C to 125°C), and maintain shielded ferrite core construction for electromagnetic containment.

The substitute part holds active product status, ensuring ongoing availability and supply chain support. Both components are ROHS3 compliant and carry EAR99 export classification, maintaining regulatory alignment with the original design.

Design Considerations:

The CDRH127L125NP-102MC provides enhanced electrical performance relative to the original part. The current rating of 640 mA exceeds the original 300 mA specification, and the DC resistance of 1.495 Ohm is substantially lower than the original 5.85 Ohm maximum. These characteristics result in reduced power dissipation and improved thermal performance in the application circuit.

Physical dimensions differ between the two parts. The substitute occupies a larger footprint (12.00mm x 12.00mm versus 6.00mm x 6.00mm) and greater height (8.00mm versus 4.50mm). PCB layout modification is required to accommodate the larger package envelope.

The substitute part is supplied in Tape & Reel packaging, supporting automated assembly processes. Both components maintain MSL Level 1 moisture sensitivity classification, requiring identical handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the CDRH127L125NP-102MC directly replace the ASPI-6045T-102M-T without circuit modification?

A: Electrical substitution is valid. Both inductors deliver 1 mH inductance at 100 kHz test frequency with identical tolerance and operating temperature range. The substitute part provides superior current handling and lower DC resistance, which benefits circuit performance. However, PCB layout modification is mandatory due to the larger physical footprint (12.00mm x 12.00mm versus 6.00mm x 6.00mm).

Q: What is the significance of the different core construction types (wirewound versus drum core)?

A: Both wirewound and drum core constructions with ferrite material deliver equivalent inductance performance at the specified test frequency. The construction difference does not affect the primary electrical parameter (inductance value) or the shielding effectiveness. The drum core design of the substitute part contributes to its lower DC resistance and higher current rating.

Q: Are there any compliance or regulatory differences between these parts?

A: Both components are ROHS3 compliant and carry EAR99 export classification. Moisture sensitivity levels are identical (MSL Level 1). No regulatory barriers exist to substitution. The CDRH127L125NP-102MC maintains full compliance with the original design requirements.

Q: How does the lower DC resistance of the substitute part affect circuit operation?

A: Lower DC resistance (1.495 Ohm versus 5.85 Ohm) reduces resistive power dissipation in the inductor. This results in lower operating temperature and improved efficiency in the application circuit. The substitute part's enhanced thermal performance is beneficial for circuits operating at or near the original current rating.

Q: What packaging format is the substitute part supplied in?

A: The CDRH127L125NP-102MC is supplied in Tape & Reel (TR) format, supporting automated pick-and-place assembly. The original part packaging format is not specified in the available data. Tape & Reel packaging is standard for high-volume surface mount production.

Q: Is the higher saturation current (830 mA) of the substitute part relevant for this application?

A: The saturation current specification indicates the current level at which the inductor begins to lose inductance due to core saturation. The original part saturates at 300 mA, while the substitute saturates at 830 mA. For applications operating at or below 300 mA, this difference is not operationally significant. For applications requiring higher current capability, the substitute part provides additional design margin.
