Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAL45VB332K is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 3.3 mH (±10% tolerance band)
• Mounting type: Through hole axial configuration
• Component type: Wirewound inductor
• Shielding classification: Unshielded

Secondary Compatibility Criteria:

• Current rating: Substitute must support minimum 75 mA continuous operation
• DC resistance: Substitute must not exceed 65 Ohm maximum
• Operating temperature range: Substitute must cover or exceed -25°C ~ 105°C
• Package / case: Axial form factor

The AIAP-01-332K-T from Abracon LLC satisfies all primary matching criteria and exceeds secondary compatibility requirements through higher current rating (83 mA) and lower DC resistance (29 Ohm maximum).

Parameter Comparison

Engineering Selection Recommendations

The AIAP-01-332K-T is a direct functional substitute for the CAL45VB332K based on the following engineering criteria:

Electrical Compatibility: Both components provide identical 3.3 mH inductance with ±10% tolerance. The substitute exhibits superior electrical performance through 29 Ohm maximum DC resistance compared to 65 Ohm, resulting in lower power dissipation. Current rating of 83 mA exceeds the original 75 mA specification, providing operational margin.

Mechanical Compatibility: Both components utilize through-hole axial mounting with identical package classification. Physical dimensions differ slightly (0.130" Dia x 0.360" L for substitute versus 0.173" Dia x 0.315" L for original), requiring verification of board layout constraints.

Product Status and Compliance: The AIAP-01-332K-T is classified as active product status, ensuring continued availability and supply chain stability. The substitute carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Both components are classified as EAR99 and share identical HTSUS code 8504.50.8000.

Temperature Performance: The substitute extends operating temperature range to -40°C ~ 105°C, providing enhanced low-temperature performance compared to the original -25°C ~ 105°C specification.

Frequently Asked Questions (FAQ)

Q: Can the AIAP-01-332K-T directly replace the CAL45VB332K in existing designs?

A: The AIAP-01-332K-T provides electrical and functional equivalence for the CAL45VB332K. Physical dimensions differ; board layout verification is required to confirm mechanical fit within existing PCB footprints.

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

A: The AIAP-01-332K-T exhibits 29 Ohm maximum DC resistance compared to 65 Ohm in the original. This reduction decreases resistive losses and heat generation during operation, improving overall circuit efficiency.

Q: Are there any compliance differences between the two parts?

A: The AIAP-01-332K-T carries RoHS3 compliance and REACH unaffected status. Both components share EAR99 classification and identical HTSUS coding. The substitute meets current regulatory requirements for electronic component manufacturing.

Q: Does the higher current rating of the substitute affect circuit operation?

A: The AIAP-01-332K-T is rated for 83 mA continuous current, exceeding the original 75 mA specification. This provides operational margin and does not negatively affect circuit function when used in applications designed for 75 mA operation.

Q: What are the physical dimension differences, and do they matter?

A: Original CAL45VB332K: 0.173" Dia x 0.315" L (4.40mm x 8.00mm). Substitute AIAP-01-332K-T: 0.130" Dia x 0.360" L (3.30mm x 9.14mm). The substitute is narrower but slightly longer. PCB footprint and component spacing must be verified for compatibility.

Q: Is the extended temperature range of the substitute beneficial?

A: The AIAP-01-332K-T operates from -40°C ~ 105°C compared to the original -25°C ~ 105°C. The extended low-temperature specification provides enhanced performance in applications requiring operation below -25°C.
