CDH63NP-560KC Equivalent & Substitute Parts

Part Overview

The CDH63NP-560KC is a 56 µH unshielded wirewound inductor manufactured by Sumida America Components Inc., rated for 420 mA continuous current with a maximum DC resistance of 1.13 Ohm. This component is classified as obsolete product status. Locating equivalent substitute parts is necessary due to discontinued availability and the need for continued supply chain support in applications requiring fixed inductance filtering, energy storage, or signal conditioning circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDH63NP-560KC is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 56 µH (exact match required)
• Mounting type: Surface Mount (exact match required)
• Current rating: Minimum 420 mA continuous current capability
• Saturation current: Minimum 530 mA

Secondary Compatibility Factors:

• DC resistance: Lower values preferred to minimize power dissipation
• Physical dimensions: Nonstandard package footprint compatibility
• RoHS and MSL compliance: ROHS3 Compliant and MSL 1 required

The substitute part SPD62R-563M meets the primary inductance and mounting requirements while providing superior current handling capability (680 mA rated, 680 mA saturation). Physical dimensions remain within acceptable tolerance for nonstandard SMD applications.

Engineering Selection Recommendations

SPD62R-563M as Primary Substitute:

The SPD62R-563M is an active product from API Delevan Inc. and serves as the direct equivalent for CDH63NP-560KC applications. Both components share identical 56 µH inductance values and surface mount nonstandard package configurations. The substitute provides enhanced electrical performance with 680 mA current rating and saturation current, exceeding the original 420 mA / 530 mA specifications by 61.9% and 28.3% respectively.

The SPD62R-563M features lower DC resistance (850 mOhm vs. 1.13 Ohm), resulting in reduced power dissipation and improved thermal performance. The shielded drum core construction of the substitute provides electromagnetic interference mitigation compared to the unshielded wirewound design of the original part.

Physical dimensions show minimal variation (6.60mm x 6.20mm x 3.00mm vs. 6.30mm x 6.10mm x 2.90mm), maintaining compatibility with existing PCB layouts designed for nonstandard SMD packages. Both components maintain ROHS3 compliance and MSL 1 ratings, ensuring equivalent environmental and moisture handling requirements.

The substitute's active product status ensures continued availability and supply chain reliability, addressing the obsolescence constraint of the original CDH63NP-560KC.

Frequently Asked Questions (FAQ)

Q: Can SPD62R-563M directly replace CDH63NP-560KC in all applications?

A: SPD62R-563M meets the core electrical requirements (56 µH inductance, surface mount, nonstandard package) and exceeds current handling specifications. The shielded construction and lower DCR provide performance improvements. Physical dimensions differ by approximately 0.30mm in length, 0.10mm in width, and 0.10mm in height; PCB layout verification is required for space-constrained designs.

Q: What is the impact of the inductance tolerance difference (±10% vs. ±20%)?

A: The original CDH63NP-560KC specifies ±10% tolerance, while SPD62R-563M specifies ±20%. For applications requiring tighter inductance control, the substitute's wider tolerance may necessitate circuit performance validation. Both tolerances remain within standard industrial specifications for fixed inductors.

Q: Does the shielded design of SPD62R-563M affect circuit performance?

A: The shielded drum core construction of SPD62R-563M reduces electromagnetic radiation and susceptibility compared to the unshielded wirewound design. This typically improves EMI performance in sensitive applications. No adverse effects are expected; performance improvements are anticipated in noise-sensitive circuits.

Q: Are there packaging differences between the two parts?

A: CDH63NP-560KC is supplied in standard packaging format. SPD62R-563M is supplied in Tape & Reel (TR) format. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings. Tape & Reel packaging is standard for high-volume surface mount assembly operations.

Q: What is the significance of the operating temperature specification?

A: SPD62R-563M specifies -55°C ~ 125°C operating range. The original CDH63NP-560KC does not provide operating temperature data. The substitute's specified range covers standard industrial and commercial temperature requirements. Applications requiring extended temperature operation should reference the SPD62R-563M datasheet for performance characteristics at temperature extremes.
