Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SDCL1608C4N7STDF is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 4.7 nH within ±0.3 nH tolerance
• Package / Case: 0603 (1608 Metric)
• Shielding type: Unshielded
• Mounting type: Surface Mount
• Operating temperature range: -55°C to 125°C minimum

Acceptable Variation Parameters:

• Current Rating: Substitute must equal or exceed 500 mA
• DC Resistance (DCR): Substitute must not exceed 200 mOhm maximum
• Q @ Freq: Substitute must equal or exceed 10 @ 100 MHz

The BSCH001608084N7S00 from Pulse Electronics meets all mandatory matching criteria and exceeds performance requirements in current rating (600 mA vs. 500 mA) and DC resistance (160 mOhm vs. 200 mOhm maximum). Both components share identical inductance specifications, package dimensions, and operating temperature ranges.

Engineering Selection Recommendations

Primary Part: SDCL1608C4N7STDF

The SDCL1608C4N7STDF is the specified component with active production status and confirmed inventory availability (1025 units). This part meets all circuit requirements and should be used as the first-choice selection when available.

Substitute Part: BSCH001608084N7S00

The BSCH001608084N7S00 from Pulse Electronics is a direct functional equivalent with superior electrical performance characteristics. This substitute is appropriate for the following conditions:

• Primary part supply constraints or extended lead times
• Design flexibility requiring multiple qualified sources
• Applications benefiting from improved DC resistance (160 mOhm vs. 200 mOhm maximum)
• Applications requiring higher current margin (600 mA vs. 500 mA rating)

Both components carry identical moisture sensitivity ratings (MSL 1 - Unlimited) and operate across the same temperature envelope (-55°C to 125°C). The substitute part maintains full mechanical and electrical compatibility with the 0603 (1608 Metric) package footprint and surface mount assembly process.

The BSCH001608084N7S00 demonstrates ROHS3 compliance and REACH unaffected status, providing additional regulatory alignment for applications with environmental compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the BSCH001608084N7S00 be used as a direct replacement for the SDCL1608C4N7STDF?

A: Yes. Both components share identical inductance values (4.7 nH ±0.3 nH), package dimensions (0603 / 1608 Metric), operating temperature ranges (-55°C to 125°C), and quality factors (10 @ 100 MHz). The substitute part exceeds the current rating and DC resistance specifications of the main part, making it functionally equivalent and electrically superior for this application.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer origin and self-resonant frequency. The SDCL1608C4N7STDF has a self-resonant frequency of 6 GHz, while the BSCH001608084N7S00 operates at 4.75 GHz. The substitute part also provides lower maximum DC resistance (160 mOhm vs. 200 mOhm) and higher current rating (600 mA vs. 500 mA). Both differences favor the substitute part in terms of electrical performance.

Q: Are the physical dimensions identical?

A: Yes. Both components are packaged in the 0603 (1608 Metric) case with identical length (0.063" / 1.60mm), width (0.031" / 0.80mm), and maximum seated height (0.037" / 0.95mm). They are mechanically interchangeable on PCB layouts designed for the 0603 footprint.

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

A: Both the SDCL1608C4N7STDF and BSCH001608084N7S00 carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Can these parts be used interchangeably in high-frequency applications?

A: Both components are rated for high-frequency operation with Q factors of 10 @ 100 MHz. The self-resonant frequencies differ (6 GHz vs. 4.75 GHz), which may affect performance in applications operating near or above 4.75 GHz. Circuit-specific frequency requirements should be evaluated to determine which part is appropriate for the intended application.

Q: What packaging formats are available for both parts?

A: Both components are supplied in Tape & Reel (TR) packaging, suitable for automated surface mount assembly processes.

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

A: The BSCH001608084N7S00 explicitly carries ROHS3 compliance and REACH unaffected status certifications. Both parts are classified under ECCN EAR99 and HTSUS 8504.50.8000. Applications with specific environmental or regulatory requirements should reference the substitute part's compliance documentation.
