CDR74BNP-220MC Equivalent & Substitute Parts

Part Overview

The CDR74BNP-220MC is a 22 µH shielded surface mount inductor manufactured by Sumida America Components Inc. This fixed inductor is rated for 1.12 A continuous current with a maximum DC resistance of 130mOhm and operates across a temperature range of -25°C to 80°C. The component features ferrite core construction with shielding and is RoHS3 compliant.

The CDR74BNP-220MC is classified as obsolete. Locating equivalent or substitute inductors with matching electrical and mechanical specifications is necessary for design continuity, procurement planning, and system reliability in applications where this component was originally specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDR74BNP-220MC is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value: 22 µH with ±20% tolerance
• Shielded construction to maintain electromagnetic isolation
• Ferrite core material for consistent performance characteristics
• Surface mount technology for PCB compatibility

Mechanical Compatibility Requirements:

• Nonstandard package footprint matching original dimensions (7.80mm x 7.00mm)
• Height compatibility with existing PCB layouts (4.90mm maximum seated height)
• Surface mount mounting type

Functional Compatibility Requirements:

• Current rating sufficient for application requirements (minimum 1.12 A)
• DC resistance within acceptable operating parameters
• Operating temperature range coverage for intended application environment
• RoHS3 compliance for regulatory alignment

The CDRH6D26HPNP-220MC qualifies as a substitute based on matching inductance value, tolerance, core material, shielding, and mounting type. Differences in current rating, DC resistance, temperature range, and physical dimensions must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The CDR74BNP-220MC is obsolete, making the CDRH6D26HPNP-220MC the appropriate substitute from an availability and lifecycle perspective. The substitute part is classified as active and maintains current manufacturing status with Sumida America Components Inc.

Compliance Alignment: Both parts maintain RoHS3 compliance and MSL 1 moisture sensitivity rating, ensuring regulatory and environmental compatibility across applications.

Electrical Performance: The substitute part provides equivalent inductance (22 µH) and tolerance (±20%) with improved current handling capability (1.2 A versus 1.12 A) and defined saturation current (1.7 A). The increased DC resistance (174mOhm versus 130mOhm maximum) represents a trade-off that must be evaluated against specific circuit requirements and thermal constraints.

Thermal Operating Range: The substitute part extends the operating temperature range to -40°C to 105°C, providing broader environmental coverage compared to the original part's -25°C to 80°C specification.

Physical Footprint: The substitute part features a smaller footprint (6.70mm x 6.70mm versus 7.80mm x 7.00mm) and reduced height (2.50mm versus 4.90mm). PCB layout compatibility must be confirmed before implementation.

Frequently Asked Questions (FAQ)

Q: Can the CDRH6D26HPNP-220MC be used as a direct replacement for the CDR74BNP-220MC?

A: The CDRH6D26HPNP-220MC matches the critical electrical specifications (22 µH inductance, ±20% tolerance, ferrite core, shielded construction) and mounting type. However, the smaller physical dimensions and increased DC resistance require verification of PCB layout compatibility and circuit performance impact before implementation.

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

A: The substitute part specifies 174mOhm maximum DC resistance compared to 130mOhm maximum in the original part. This 44mOhm increase will result in higher resistive losses and heat generation under the same current conditions. Applications sensitive to power dissipation or thermal performance must evaluate this parameter against design margins.

Q: Does the substitute part's smaller footprint affect PCB compatibility?

A: Yes. The CDRH6D26HPNP-220MC measures 6.70mm x 6.70mm with 2.50mm maximum height, compared to the original 7.80mm x 7.00mm with 4.90mm maximum height. Existing PCB layouts designed for the CDR74BNP-220MC footprint require modification to accommodate the substitute part's dimensions.

Q: Are both parts available in the same packaging format?

A: No. The original CDR74BNP-220MC packaging format is not specified. The substitute CDRH6D26HPNP-220MC is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations.

Q: What is the practical difference in current rating between the two parts?

A: The original part is rated for 1.12 A continuous current. The substitute part is rated for 1.2 A continuous current with a saturation current of 1.7 A. For applications operating at or near the original 1.12 A specification, the substitute part provides adequate current handling with additional margin.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental requirements are equivalent between the two components.
