Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAL45VB822K is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 8.2 mH with ±10% tolerance
• Mounting type: Through hole axial configuration
• Shielding classification: Unshielded wirewound construction
• Package case: Axial form factor

Secondary Compatibility Factors:

• Current rating: Substitute must support minimum 50 mA continuous operation
• DC resistance: Substitute DCR must not exceed circuit design limits
• Operating temperature: Substitute must cover or exceed -25°C to 105°C range
• Moisture sensitivity: MSL 1 classification ensures unlimited shelf life compatibility

The AIAP-01-822K-T from Abracon LLC meets all primary matching criteria and provides enhanced specifications in current rating (54 mA) and reduced DC resistance (75 Ohm), making it a direct functional substitute for the obsolete CAL45VB822K.

Engineering Selection Recommendations

The AIAP-01-822K-T is the qualified substitute for the obsolete CAL45VB822K based on the following engineering factors:

Functional Equivalence: Both components provide identical inductance values (8.2 mH) with matching tolerance specifications (±10%), ensuring circuit performance consistency. The axial through-hole configuration and unshielded wirewound construction are identical, permitting direct board-level replacement without layout modifications.

Performance Enhancement: The AIAP-01-822K-T provides improved electrical characteristics with 54 mA current rating (8% higher than the original 50 mA specification) and reduced DC resistance of 75 Ohm compared to the original 125 Ohm maximum. These improvements reduce power dissipation and thermal stress in the application.

Compliance and Availability: The AIAP-01-822K-T maintains active product status with confirmed inventory availability (1021 pieces in stock). The component is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements. The extended operating temperature range (-40°C to 105°C) provides additional thermal margin compared to the original specification.

Moisture and Environmental Compatibility: Both components share MSL 1 classification, ensuring unlimited shelf life and identical moisture handling requirements. The ECCN and HTSUS classifications remain consistent across both parts.

Frequently Asked Questions (FAQ)

Q: Can the AIAP-01-822K-T directly replace the CAL45VB822K without circuit modifications?

A: Yes. Both components share identical inductance values (8.2 mH), tolerance specifications (±10%), axial through-hole mounting configuration, and unshielded wirewound construction. Direct board-level substitution is supported without design changes.

Q: What is the significance of the lower DC resistance in the AIAP-01-822K-T?

A: The AIAP-01-822K-T exhibits 75 Ohm maximum DC resistance compared to 125 Ohm in the original part. This 40% reduction in series resistance decreases power dissipation (I²R losses) and thermal generation, improving overall circuit efficiency and component reliability.

Q: Are there physical dimension differences between these components?

A: Yes. The CAL45VB822K measures 0.173" diameter × 0.315" length (4.40mm × 8.00mm), while the AIAP-01-822K-T measures 0.130" diameter × 0.360" length (3.30mm × 9.14
