CAL45VB560K Equivalent & Substitute Parts

Part Overview

The CAL45VB560K is a 56 µH unshielded wirewound inductor manufactured by Taiyo Yuden, rated for 710 mA continuous current with a maximum DC resistance of 750 mOhm. This component is designed for through-hole axial mounting applications requiring fixed inductance in the 56 µH range. The part is classified as obsolete, making identification of equivalent substitutes necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the CAL45VB560K is based on the following critical parameters that must align across equivalent components:

Primary Matching Criteria:

• Inductance value: 56 µH (exact match required)
• Inductance tolerance: ±10% (matching tolerance specification)
• Shielding type: Unshielded (electromagnetic shielding characteristics must be identical)
• Mounting type: Through hole axial (physical and electrical connection method)
• Package / case: Axial (form factor and pin configuration)

Secondary Compatibility Parameters:

• Current rating: Substitute must support the application's current requirements
• DC resistance: Lower DCR values provide improved efficiency; higher values may be acceptable depending on circuit design
• Operating temperature range: Substitute must cover or exceed the application's temperature requirements
• Moisture sensitivity level: MSL 1 rating ensures unlimited shelf life compatibility

The AIAP-01-560K-T from Abracon LLC meets all primary matching criteria and is therefore classified as a direct equivalent substitute for the CAL45VB560K.

Parameter Comparison

Engineering Selection Recommendations

The AIAP-01-560K-T is an active product from Abracon LLC and serves as the functional equivalent to the obsolete CAL45VB560K. Both components share identical inductance values, tolerance specifications, shielding characteristics, and axial through-hole mounting configuration.

Current Rating Consideration: The AIAP-01-560K-T is rated for 650 mA continuous current, compared to the CAL45VB560K's 710 mA rating. Applications operating at or below 650 mA continuous current are fully compatible. Applications requiring current levels between 650 mA and 710 mA require circuit-level evaluation to determine if the lower current rating presents a constraint.

DC Resistance Advantage: The AIAP-01-560K-T features a maximum DC resistance of 470 mOhm, which is lower than the CAL45VB560K's 750 mOhm specification. This represents improved electrical efficiency and reduced power dissipation in the substitute component.

Temperature Range: The AIAP-01-560K-T operates across -40°C to 105°C, extending the lower temperature limit by 15°C compared to the CAL45VB560K's -25°C to 105°C range.

Compliance Status: The AIAP-01-560K-T carries RoHS3 compliance and REACH unaffected status, supporting modern regulatory requirements for component procurement.

Frequently Asked Questions (FAQ)

Q: Can the AIAP-01-560K-T directly replace the CAL45VB560K in all applications?

A: The AIAP-01-560K-T is a direct substitute for applications where the continuous current requirement does not exceed 650 mA. Both components provide identical 56 µH inductance, ±10% tolerance, unshielded configuration, and axial through-hole mounting. Applications requiring the full 710 mA current rating of the original part require evaluation of the substitute's 650 mA rating against actual circuit current demands.

Q: What is the physical size difference between these components?

A: The CAL45VB560K measures 0.173" diameter × 0.315" length (4.40mm × 8.00mm). The AIAP-01-560K-T measures 0.130" diameter × 0.360" length (3.30mm × 9.14mm). Both are axial through-hole components with compatible PCB footprints, though the substitute is slightly narrower in diameter and longer in axial length.

Q: Does the lower DC resistance of the AIAP-01-560K-T affect circuit performance?

A: The AIAP-01-560K-T's 470 mOhm maximum DC resistance is lower than the CAL45VB560K's 750 mOhm specification. Lower DC resistance reduces resistive losses and heat generation, which is beneficial for circuit efficiency. This difference does not negatively impact circuit performance and typically improves thermal characteristics.

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

A: The AIAP-01-560K-T is RoHS3 compliant and REACH unaffected, supporting current regulatory requirements. The CAL45VB560K, being an obsolete part, may not carry current compliance certifications. Both components carry MSL 1 (unlimited moisture sensitivity) ratings and EAR99 export classification.

Q: What is the inductance test frequency for each component?

A: The CAL45VB560K inductance is tested at 2.52 MHz. The AIAP-01-560K-T inductance is tested at 1 kHz. Both components maintain the specified 56 µH inductance value within ±10% tolerance at their respective test frequencies. The difference in test frequency reflects different measurement methodologies but does not affect functional equivalence for standard circuit applications.
