CDH53-560KC Equivalent & Substitute Parts

Part Overview

The CDH53-560KC is a 56 µH unshielded drum core wirewound inductor manufactured by Sumida America Components Inc., rated for 500 mA continuous current with a maximum DC resistance of 870 mOhm. This surface mount component operates across the temperature range of -30°C to 100°C and is specified for 1 kHz inductance testing.

The CDH53-560KC is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing production requirements, field repairs, and design continuity where this inductor specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDH53-560KC is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Inductance value: 56 µH
• Inductance tolerance: ±10%
• Current rating: 500 mA minimum
• DC resistance: 870 mOhm maximum
• Inductance test frequency: 1 kHz

Mechanical Equivalence Criteria:

• Core material: Ferrite
• Core configuration: Drum core, unshielded
• Mounting type: Surface mount
• Package dimensions: 6.00 mm × 5.20 mm × 3.20 mm maximum height
• Moisture sensitivity: MSL 1 or better

Compliance Considerations:

• RoHS compliance status
• Operating temperature range capability

The CDH53NP-560KC meets all electrical and mechanical equivalence criteria and is therefore classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The CDH53NP-560KC is the direct substitute for the obsolete CDH53-560KC. Both components are manufactured by Sumida America Components Inc. within the same CDH53 series and share identical electrical specifications and mechanical dimensions.

Key Advantages of CDH53NP-560KC:

The substitute part maintains active product status, ensuring continued availability and supply chain reliability. The CDH53NP-560KC is ROHS3 compliant, meeting current environmental and regulatory requirements, whereas the main part is non-compliant. The extended operating temperature range of -40°C to 100°C provides additional thermal margin compared to the -30°C to 100°C range of the main part. Tape & Reel packaging is standard for automated assembly processes.

Compatibility Confirmation:

All critical electrical parameters—inductance, tolerance, current rating, and DC resistance—are identical. Physical dimensions and mounting type are unchanged. The substitute part is electrically and mechanically interchangeable in all applications where the CDH53-560KC was specified.

Frequently Asked Questions (FAQ)

Q: Can CDH53NP-560KC be used as a direct replacement for CDH53-560KC?

A: Yes. The CDH53NP-560KC is electrically and mechanically equivalent. All inductance, current, resistance, and dimensional specifications are identical. The substitute part is suitable for direct substitution in all circuit applications.

Q: What is the difference between the two parts?

A: The primary differences are product status, regulatory compliance, and packaging format. The CDH53-560KC is obsolete and RoHS non-compliant. The CDH53NP-560KC is an active product with ROHS3 compliance and is supplied in Tape & Reel format. The CDH53NP-560KC also provides an extended lower operating temperature limit of -40°C versus -30°C.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 6.00 mm length × 5.20 mm width with a maximum seated height of 3.20 mm. PCB footprint and mounting requirements are identical.

Q: Does the extended temperature range of CDH53NP-560KC affect circuit performance?

A: The extended range (-40°C to 100°C versus -30°C to 100°C) provides additional operational margin. For applications operating within the original -30°C to 100°C specification, both parts perform identically. Applications requiring operation below -30°C benefit from the substitute part's extended range.

Q: Is Tape & Reel packaging compatible with existing assembly processes?

A: Tape & Reel packaging is the standard format for automated surface mount assembly. If the original design used bulk packaging, conversion to Tape & Reel format is standard practice and requires no circuit design changes.

Q: Are there any compliance or certification differences?

A: The CDH53NP-560KC is ROHS3 compliant, meeting current environmental directives. The original CDH53-560KC is non-compliant. For new designs or products subject to RoHS requirements, the substitute part is the appropriate selection.
