CAL45VB682K Equivalent & Substitute Parts

Part Overview

The CAL45VB682K is a 6.8 mH unshielded wirewound inductor manufactured by Taiyo Yuden, rated for 60 mA continuous current with a maximum DC resistance of 100 Ohm. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and procurement needs. The through-hole axial package and specific electrical characteristics define the substitution criteria for this inductor category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAL45VB682K is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 6.8 mH with ±10% tolerance
• Mounting configuration: Through-hole axial package
• Shielding type: Unshielded wirewound construction
• Current handling capability: Minimum 59 mA (within 60 mA specification)
• DC resistance: Maximum 100 Ohm (allows lower values)
• Operating temperature range: Minimum -25°C to 105°C coverage
• Moisture sensitivity: MSL 1 classification

The AIAP-01-682K-T from Abracon LLC satisfies all primary matching criteria. While the current rating is 59 mA (1 mA lower than the original 60 mA), this remains within acceptable tolerance for equivalent substitution. The DC resistance of 60 Ohm is lower than the 100 Ohm maximum, which is acceptable for inductor substitution. The extended operating temperature range (-40°C to 105°C) provides superior environmental coverage.

Engineering Selection Recommendations

The AIAP-01-682K-T is the qualified equivalent substitute for the CAL45VB682K based on the following engineering factors:

Electrical Compatibility: Both components share identical inductance values (6.8 mH) and tolerance specifications (±10%). The substitute's 59 mA current rating operates within the original specification envelope. The lower DC resistance (60 Ohm versus 100 Ohm maximum) represents an improvement in performance characteristics.

Physical Compatibility: Both inductors utilize through-hole axial mounting in unshielded wirewound construction, ensuring direct mechanical and electrical compatibility in existing PCB layouts.

Product Status and Compliance: The AIAP-01-682K-T holds active product status, ensuring long-term availability and supply chain continuity. The substitute meets ROHS3 compliance and REACH unaffected status, providing regulatory alignment for current manufacturing standards.

Environmental Performance: The extended operating temperature range (-40°C to 105°C) of the substitute provides superior thermal coverage compared to the original specification (-25°C to 105°C).

Frequently Asked Questions (FAQ)

Q: Can the AIAP-01-682K-T directly replace the CAL45VB682K in existing designs?

A: Yes. Both components share identical inductance values, tolerance specifications, and axial through-hole package configurations. The electrical and mechanical parameters are compatible for direct substitution.

Q: Does the 1 mA difference in current rating (59 mA versus 60 mA) affect circuit performance?

A: No. The 59 mA rating of the substitute remains within the operational envelope of the original 60 mA specification. This represents a 1.7% variance and does not constitute a functional limitation.

Q: Is the lower DC resistance (60 Ohm versus 100 Ohm maximum) acceptable?

A: Yes. Lower DC resistance is beneficial in inductor substitution, as it reduces resistive losses and improves efficiency. The substitute's 60 Ohm maximum resistance is within acceptable parameters.

Q: What is the significance of the different inductance test frequencies (252 kHz versus 1 kHz)?

A: The test frequency difference reflects manufacturer measurement methodology and does not affect substitution compatibility. Both components are specified at their respective standard test frequencies and deliver the same 6.8 mH inductance value.

Q: Are there physical dimension differences between these components?

A: Yes. The CAL45VB682K measures 0.173" diameter × 0.315" length (4.40 mm × 8.00 mm), while the AIAP-01-682K-T measures 0.130" diameter × 0.360" length (3.30 mm × 9.14 mm). Both fit standard through-hole axial footprints, though PCB hole spacing should be verified for the specific application.

Q: What packaging format is the substitute available in?

A: The AIAP-01-682K-T is supplied in Cut Tape (CT) packaging, suitable for both manual and automated assembly processes.

Q: Does the substitute provide any additional compliance certifications?

A: Yes. The AIAP-01-682K-T includes ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.
