SDCL1608C47NJTDF Equivalent & Substitute Parts

Part Overview

The SDCL1608C47NJTDF is a 47 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 700 mOhm and operates across the temperature range of -55°C to 125°C. The part is classified as Active product status and is available in 0603 (1608 Metric) package format with Tape & Reel packaging.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across critical parameters including inductance value, tolerance, current rating, DC resistance, operating temperature range, and package dimensions. Substitution becomes necessary due to inventory availability, supply chain considerations, or design optimization requirements.

Substitute Part Grouping Explanation

Substitute parts for the SDCL1608C47NJTDF are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following critical parameters:

Electrical Parameters:

• Inductance value: 47 nH (exact match required)
• Inductance tolerance: ±5% (exact match required)
• DC resistance: 700 mOhm maximum (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Core material: Ceramic (exact match required)
• Shielding configuration: Unshielded (exact match required)

Mechanical Parameters:

• Package format: 0603 (1608 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Physical dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm) (exact match required)
• Maximum seated height: 0.037" (0.95mm) (exact match required)

Allowable Variations:

• Current rating: Substitute parts may have equal or higher current rating than the main part
• Self-resonant frequency: Variations permitted within acceptable operating bandwidth
• Q factor: Variations permitted provided electrical performance is maintained

Parameter Comparison

Engineering Selection Recommendations

Both the SDCL1608C47NJTDF and the 7447860147 are classified as Active products with equivalent electrical specifications for the core inductance parameters. The Würth Elektronik 7447860147 provides a higher current rating of 350 mA compared to the Sunlord part's 300 mA rating, which represents an operational advantage in applications requiring higher current capacity without exceeding the maximum DC resistance specification.

Both parts maintain identical operating temperature ranges, package dimensions, and moisture sensitivity classifications. Both are compliant with EAR99 export control classification and share the same HTSUS commodity code.

The primary difference between these parts is the self-resonant frequency specification: the Sunlord SDCL1608C47NJTDF operates at 1.2 GHz while the Würth Elektronik 7447860147 operates at 900 MHz. This difference must be evaluated against specific circuit requirements and frequency-dependent performance criteria in the target application.

Selection between these parts should be based on current requirement compatibility, frequency response requirements, and supply chain availability. Both parts are suitable for direct substitution in applications where the specified electrical and mechanical parameters are met.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 7447860147 be used as a direct replacement for the SDCL1608C47NJTDF?

A: Yes, the 7447860147 is a direct substitute for the SDCL1608C47NJTDF. Both parts share identical inductance values (47 nH), tolerance specifications (±5%), DC resistance ratings (700 mOhm maximum), operating temperature ranges (-55°C to 125°C), and package dimensions (0603 / 1608 Metric). The substitute part provides a higher current rating (350 mA versus 300 mA), which is compatible with the original design.

Q: What is the significance of the different self-resonant frequencies?

A: The self-resonant frequency (SRF) defines the frequency at which the inductor transitions from inductive to capacitive behavior. The SDCL1608C47NJTDF has an SRF of 1.2 GHz while the 7447860147 has an SRF of 900 MHz. Applications operating near or above these frequencies must account for this difference in frequency response characteristics. For applications operating well below these frequencies, this difference has minimal impact.

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

A: Yes, both parts are supplied in Tape & Reel (TR) packaging and are available in the 0603 (1608 Metric) surface mount package. Physical dimensions are identical: 0.063" L x 0.031" W (1.60mm x 0.80mm) with a maximum seated height of 0.037" (0.95mm).

Q: What is the moisture sensitivity level for these parts?

A: Both the SDCL1608C47NJTDF and 7447860147 are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts share identical export control classifications (EAR99) and HTSUS commodity codes (8504.50.8000). The Würth Elektronik 7447860147 carries RoHS3 compliance and REACH Unaffected status certifications. Both parts are Active products with no known end-of-life announcements.

Q: What is the Q factor specification and how does it compare?

A: Both parts specify a Q factor of 12 at 100 MHz, indicating equivalent quality factor performance at this test frequency. This parameter reflects the ratio of reactive power to dissipated power in the inductor.
