CDH53-150KC Equivalent & Substitute Parts

Part Overview

The CDH53-150KC is a 15 µH unshielded drum core wirewound inductor manufactured by Sumida America Components Inc., rated for 1 A continuous current with a maximum DC resistance of 250 mOhm. This surface mount component is designed for applications requiring fixed inductance in compact nonstandard packages.

The CDH53-150KC is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing production requirements, field repairs, and design continuity where this inductor specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDH53-150KC is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Inductance value: 15 µH
• Inductance tolerance: ±10%
• Current rating: 1 A minimum
• DC resistance: 250 mOhm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded

Mechanical Equivalence Criteria:

• Mounting type: Surface Mount
• Package classification: Nonstandard
• Physical footprint: 6.00 mm × 5.20 mm × 3.20 mm maximum height
• Inductance measurement standard: 1 kHz test frequency

The CDH53NP-150KC satisfies all electrical and mechanical equivalence requirements and is therefore classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The CDH53NP-150KC is the direct functional equivalent of the obsolete CDH53-150KC. Both components are manufactured by Sumida America Components Inc. within the CDH53 series and share identical electrical specifications and mechanical dimensions.

Selection Basis:

The CDH53NP-150KC is recommended as the primary substitute based on:

1. Product Status: The CDH53NP-150KC maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete CDH53-150KC.

2. Regulatory Compliance: The CDH53NP-150KC is ROHS3 compliant, meeting current environmental and regulatory requirements. The original CDH53-150KC is non-compliant with modern RoHS standards.

3. Operating Temperature Range: The CDH53NP-150KC extends the lower operating temperature limit to -40°C, providing a wider operational envelope than the CDH53-150KC (-30°C minimum).

4. Electrical and Mechanical Equivalence: All critical parameters—inductance, current rating, DC resistance, core material, shielding, mounting type, and physical dimensions—are identical between both parts.

5. Packaging Consideration: The CDH53NP-150KC is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. The original CDH53-150KC was supplied in bulk packaging. This difference does not affect electrical or mechanical compatibility but may require adjustment to procurement and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can the CDH53NP-150KC be used as a direct replacement for the CDH53-150KC in existing designs?

A: Yes. The CDH53NP-150KC is electrically and mechanically equivalent to the CDH53-150KC. All critical parameters—inductance value, tolerance, current rating, DC resistance, core material, shielding, and physical dimensions—are identical. The component can be substituted without circuit redesign or PCB layout modification.

Q: What is the difference between the CDH53-150KC and CDH53NP-150KC?

A: The primary differences are product status, regulatory compliance, and packaging format. The CDH53-150KC is obsolete and RoHS non-compliant, while the CDH53NP-150KC is active production and ROHS3 compliant. The CDH53NP-150KC also has an extended lower operating temperature limit (-40°C vs. -30°C). The CDH53NP-150KC is supplied in Tape & Reel format rather than bulk packaging.

Q: Are there any compatibility issues with PCB assembly when switching from CDH53-150KC to CDH53NP-150KC?

A: No compatibility issues exist. Both components have identical surface mount footprints and physical dimensions (6.00 mm × 5.20 mm × 3.20 mm). The nonstandard package type is consistent between both parts. The Tape & Reel packaging of the CDH53NP-150KC is compatible with standard automated pick-and-place assembly equipment.

Q: Does the CDH53NP-150KC meet current regulatory requirements?

A: Yes. The CDH53NP-150KC is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components. The obsolete CDH53-150KC does not meet these requirements.

Q: What is the operating temperature range for the CDH53NP-150KC?

A: The CDH53NP-150KC operates from -40°C to 100°C, providing a wider temperature range than the original CDH53-150KC (-30°C to 100°C). This extended range supports applications requiring operation at lower ambient temperatures.

Q: Is the inductance value and tolerance identical between both parts?

A: Yes. Both the CDH53-150KC and CDH53NP-150KC are rated at 15 µH with ±10% tolerance, measured at 1 kHz. Inductance specifications are identical.

Q: Can the CDH53NP-150KC handle the same current as the CDH53-150KC?

A: Yes. Both components are rated for 1 A continuous current with a maximum DC resistance of 250 mOhm. Current handling capability is identical.
