Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLP6045LT-2R2N is determined by the following critical parameters:

• Inductance Value: Must be 2.2 µH with ±30% tolerance
• Current Rating: Minimum 5.1 A continuous current capability
• Core Type: Ferrite drum core, wirewound construction
• Shielding: Shielded configuration required
• Operating Temperature: -40°C to 105°C range
• Mounting: Surface mount, nonstandard package
• Test Frequency: 100 kHz inductance measurement standard

Both substitute parts meet these core electrical and mechanical requirements while offering improvements in specific parameters such as reduced DC resistance or increased saturation current.

Parameter Comparison

Engineering Selection Recommendations

VLS6045EX-2R2N (TDK Corporation): This substitute is the primary equivalent for the VLP6045LT-2R2N. Both parts are manufactured by TDK Corporation and share identical electrical specifications for inductance, tolerance, current rating, and operating temperature. The VLS6045EX-2R2N offers superior performance with reduced DC resistance (19 mOhm versus 26 mOhm) and higher saturation current (7.5 A versus 6.4 A). The part is active in production with RoHS3 compliance and available in Cut Tape and Digi-Reel packaging. The footprint is slightly smaller (6.00mm versus 6.80mm), which may require PCB layout verification.

CDRH6D23HPNP-2R2NC (Sumida America Components Inc.): This substitute meets the core inductance, tolerance, and temperature requirements. However, the current rating is reduced to 4.1 A, which is below the original 5.1 A specification. The saturation current is also lower at 4.4 A. This part is suitable only for applications where the actual operating current does not exceed 4.1 A. The height is significantly reduced (2.50mm versus 4.50mm), offering potential space savings in constrained designs. The part is active in production and available in Tape & Reel packaging.

Frequently Asked Questions (FAQ)

Q: Can the VLS6045EX-2R2N directly replace the VLP6045LT-2R2N without circuit modification?

A: The VLS6045EX-2R2N is electrically compatible as a direct replacement. Both parts maintain the same inductance value, tolerance, current rating, and operating temperature range. The reduced DC resistance and increased saturation current represent improvements. PCB layout verification is required due to the smaller footprint (6.00mm versus 6.80mm).

Q: Is the CDRH6D23HPNP-2R2NC suitable for all applications using the VLP6045LT-2R2N?

A: The CDRH6D23HPNP-2R2NC is suitable only for applications where the continuous operating current does not exceed 4.1 A. The original part is rated for 5.1 A, making this substitute inappropriate for designs operating at or near the original current specification. Verify actual circuit current requirements before selection.

Q: What are the packaging differences between these substitutes?

A: The VLP6045LT-2R2N uses nonstandard packaging. The VLS6045EX-2R2N is available in Cut Tape (CT) and Digi-Reel packaging. The CDRH6D23HPNP-2R2NC is supplied in Tape & Reel (TR) format. Confirm packaging compatibility with assembly equipment and procurement processes.

Q: Are there compliance or certification differences?

A: The VLS6045EX-2R2N carries RoHS3 compliance. Both substitute parts maintain MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status, matching the original part's environmental compliance profile.

Q: What is the impact of the different physical dimensions?

A: The VLS6045EX-2R2N is smaller (6.00mm versus 6.80mm footprint) with identical height (4.50mm). The CDRH6D23HPNP-2R2NC has a similar footprint (6.70mm) but significantly reduced height (2.50mm). PCB layout and component placement must be verified for each substitute to ensure clearance and thermal management requirements are met.
