Substitute Part Grouping Explanation

Substitute parts for the SDCL1005C4N3STDF are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Inductance value: 4.3 nH with ±0.3nH tolerance
• Package / Case: 0402 (1005 Metric)
• Type: Multilayer
• Material - Core: Ceramic
• Shielding: Unshielded
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 125°C

Allowable Parameter Variations:

• Current Rating: Equal to or greater than 300 mA
• DC Resistance (DCR): Equal to or less than 200mOhm Max
• Q @ Freq: Equal to or greater than 8 @ 100MHz
• Frequency - Self Resonant: Equal to or greater than 4GHz

The BSCH001005054N3SCS from Pulse Electronics meets all critical matching parameters and demonstrates improved performance in allowable variation categories, including higher current rating (400 mA), lower DC resistance (180mOhm Max), and higher self-resonant frequency (6GHz).

Parameter Comparison

Engineering Selection Recommendations

Both the SDCL1005C4N3STDF and BSCH001005054N3SCS are active production components with identical core electrical specifications and package dimensions. Selection between these parts is based on application requirements and supply chain considerations.

The SDCL1005C4N3STDF from Shenzhen Sunlord Electronics is the primary part specification with substantial inventory availability (127,658 pcs). This part is suitable for applications requiring the specified 300 mA current rating and 200mOhm maximum DC resistance.

The BSCH001005054N3SCS from Pulse Electronics is a direct substitute offering enhanced performance characteristics. This part provides a higher current rating of 400 mA, lower DC resistance of 180mOhm Max, and a higher self-resonant frequency of 6GHz compared to the primary part. The BSCH001005054N3SCS is ROHS3 compliant and REACH unaffected. This substitute is appropriate for applications where improved thermal performance or higher frequency operation is beneficial, or when Pulse Electronics supply chain availability is preferred.

Both parts share identical inductance values, tolerances, package dimensions, operating temperature ranges, and moisture sensitivity ratings. The height difference of 0.002" (0.05mm) between seated heights is negligible for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the BSCH001005054N3SCS replace the SDCL1005C4N3STDF in all applications?

A: The BSCH001005054N3SCS meets all critical electrical and mechanical parameters required for substitution. The substitute part provides equal or superior performance across all specified parameters. Direct substitution is electrically and mechanically compatible for applications designed for the SDCL1005C4N3STDF.

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

A: The primary differences are current rating (400 mA vs. 300 mA), DC resistance (180mOhm vs. 200mOhm), self-resonant frequency (6GHz vs. 4GHz), and seated height (0.024" vs. 0.026"). The BSCH001005054N3SCS offers improved performance in these parameters while maintaining identical inductance, tolerance, package, and operating temperature specifications.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 0402 (1005 Metric) package with identical length and width dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm). The seated height difference of 0.002" (0.05mm) is within standard PCB assembly tolerances and does not affect component placement or functionality.

Q: What is the inductance tolerance for both parts?

A: Both the SDCL1005C4N3STDF and BSCH001005054N3SCS have an inductance tolerance of ±0.3nH around the nominal 4.3 nH value.

Q: Are both parts suitable for high-frequency applications?

A: Both parts are suitable for high-frequency applications within their specified operating ranges. The SDCL1005C4N3STDF has a self-resonant frequency of 4GHz, while the BSCH001005054N3SCS has a self-resonant frequency of 6GHz. The Q factor at 100MHz is identical at 8 for both parts.

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

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without moisture control requirements.

Q: Are there compliance differences between the two parts?

A: The BSCH001005054N3SCS is explicitly ROHS3 compliant and REACH unaffected. Both parts are classified under ECCN EAR99 and HTSUS 8504.50.8000. Compliance documentation should be verified with the respective manufacturers for specific application requirements.
