SDCL1608C56NJTDF Equivalent & Substitute Parts

Part Overview

The SDCL1608C56NJTDF is a 56 nH unshielded multilayer ceramic inductor manufactured by Shenzhen Sunlord Electronics Co., Ltd. This surface mount component is rated for 300 mA continuous current with a maximum DC resistance of 750 mOhm and operates across the temperature range of -55°C to 125°C. The part is classified as Active product status with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across inductance value, current rating, DC resistance, package dimensions, and operating temperature specifications. Identifying qualified substitutes ensures design flexibility, supply chain continuity, and component availability across manufacturing cycles.

Parameter Comparison

Engineering Selection Recommendations

Both the SDCL1608C56NJTDF and 7447860156 are Active product status components with identical electrical and mechanical specifications across all critical parameters. Selection between these parts is based on the following factors:

Supply Chain Availability: The SDCL1608C56NJTDF maintains higher inventory levels (17,115 pcs) compared to the 7447860156 (4,911 pcs). For applications requiring immediate availability or large volume procurement, the Sunlord component offers superior stock position.

Compliance & Certifications: The Würth Elektronik 7447860156 carries explicit RoHS3 compliance and REACH Unaffected status documentation. The SDCL1608C56NJTDF does not specify these certifications in the provided parameters. For applications subject to RoHS3 or REACH regulatory requirements, the Würth Elektronik part provides documented compliance assurance.

Self-Resonant Frequency Consideration: The SDCL1608C56NJTDF exhibits a self-resonant frequency of 1.1 GHz, while the 7447860156 operates at 900 MHz. This difference does not affect substitution eligibility for DC or low-frequency AC applications but may influence performance in high-frequency circuit designs operating near or above 900 MHz.

Both components are suitable for direct substitution in applications where the specified electrical and mechanical parameters are the primary selection criteria.

Frequently Asked Questions (FAQ)

Q: Can the 7447860156 be used as a direct replacement for the SDCL1608C56NJTDF?

A: Yes. Both components share identical inductance (56 nH), current rating (300 mA), DC resistance (750 mOhm max), package dimensions (0603/1608 Metric), and operating temperature range (-55°C to 125°C). They are parametric equivalents and direct substitutes for applications where these specifications are the primary design criteria.

Q: Are there differences in self-resonant frequency between these parts?

A: Yes. The SDCL1608C56NJTDF has a self-resonant frequency of 1.1 GHz, while the 7447860156 operates at 900 MHz. For applications operating at frequencies below 900 MHz, this difference is not significant. For high-frequency designs operating near or above 900 MHz, the higher self-resonant frequency of the Sunlord component may provide performance advantages.

Q: What is the significance of the 0603 (1608 Metric) package designation?

A: The 0603 package is a standard surface mount inductor footprint measuring 0.063" length × 0.031" width (1.60mm × 0.80mm). Both substitute parts use this identical package, ensuring mechanical compatibility with existing PCB layouts and assembly processes without design modification.

Q: Do both parts require special handling for moisture sensitivity?

A: No. Both components carry Moisture Sensitivity Level (MSL) 1, which designates unlimited shelf life without moisture control requirements. Standard handling procedures for surface mount components are sufficient.

Q: Which part should be selected for RoHS3-compliant applications?

A: The Würth Elektronik 7447860156 carries explicit RoHS3 compliance certification. If RoHS3 compliance documentation is required for regulatory or customer qualification purposes, the 7447860156 is the specified choice. The SDCL1608C56NJTDF does not provide RoHS3 certification in the available parameters.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both the SDCL1608C56NJTDF and 7447860156 are supplied in Tape & Reel (TR) format, suitable for automated assembly processes and high-volume production environments.
