Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 1-1624109-1 are selected based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Mandatory Matching Criteria:

• Inductance value: 39 nH (allows tolerance variation within acceptable circuit performance margins)
• Package form factor: 0603 (1608 Metric) surface mount
• Shielding configuration: Unshielded
• Current rating: Equal to or greater than 200 mA
• Operating temperature range: Must encompass or exceed -40°C ~ 85°C

Secondary Compatibility Factors:

• DC resistance characteristics (lower DCR values indicate improved performance)
• Frequency response characteristics (self-resonant frequency and Q factor)
• RoHS and REACH compliance status
• Moisture sensitivity level

The identified substitute parts meet these criteria while offering active product status and improved availability compared to the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

Würth Elektronik 744761139C is the primary substitute for the TE Connectivity 1-1624109-1. This part maintains the 39 nH inductance specification and 0603 (1608 Metric) package form factor. The Würth part offers superior electrical characteristics including significantly lower DC resistance (210 mOhm versus 3 Ohm), higher current rating (600 mA versus 200 mA), and extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C). The part is active in production status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The higher Q factor (36 @ 250 MHz) and increased self-resonant frequency (2.2 GHz) provide improved frequency response characteristics.

Stackpole Electronics LTF0603GT39N serves as an alternative substitute, maintaining the 39 nH inductance and 0603 package specification with active product status. However, this part has limited parameter documentation in the provided data set, restricting detailed electrical comparison. Selection of this part requires verification of current rating and operating temperature specifications against circuit requirements.

Both substitute parts are compliant with REACH regulations and carry EAR99 ECCN classification, matching the regulatory profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 744761139C directly replace the TE Connectivity 1-1624109-1 in existing designs?

A: Yes, the Würth part maintains electrical equivalence across the critical parameters: 39 nH inductance, 0603 (1608 Metric) surface mount package, and unshielded configuration. The lower DC resistance and higher current rating of the Würth part provide improved performance margins. Verification of circuit-specific requirements regarding tolerance, frequency response, and temperature operation is necessary before implementation.

Q: What is the significance of the DC resistance difference between the main part and substitute parts?

A: The TE Connectivity part specifies 3 Ohm maximum DC resistance, while the Würth part specifies 210 mOhm maximum. Lower DC resistance reduces power dissipation and heat generation in the inductor during operation. This represents a substantial improvement in the Würth substitute, resulting in lower operating temperatures and improved circuit efficiency.

Q: Are there package compatibility concerns when substituting these parts?

A: Both the TE Connectivity and Würth parts use the 0603 (1608 Metric) package form factor with surface mount mounting type. Physical dimensions are comparable (TE: 1.60mm x 0.80mm x 0.55mm height; Würth: 1.65mm x 1.15mm x 1.10mm height). The Würth part has slightly larger dimensions but remains compatible with standard 0603 PCB footprints. The Stackpole part also uses 0603 packaging.

Q: What compliance certifications apply to these substitute parts?

A: The Würth Elektronik 744761139C is ROHS3 compliant and REACH unaffected. The TE Connectivity original part has RoHS status listed as not applicable due to its obsolete classification. All parts carry EAR99 ECCN classification and fall under HTSUS code 8504.50.8000.

Q: How do the frequency characteristics compare between the main part and substitutes?

A: The TE Connectivity part exhibits Q factor of 15 @ 500 MHz and self-resonant frequency of 1.5 GHz. The Würth substitute shows Q factor of 36 @ 250 MHz and self-resonant frequency of 2.2 GHz. The higher Q factor and increased self-resonant frequency of the Würth part indicate superior high-frequency performance characteristics.

Q: What is the current rating consideration for substitution?

A: The TE Connectivity part is rated for 200 mA maximum current. The Würth substitute is rated for 600 mA, providing a 3x current margin. For applications operating at or near the 200 mA specification of the original part, the Würth substitute offers substantial headroom for transient current conditions and thermal stability.

Q: Is the extended operating temperature range of the Würth part significant?

A: The TE Connectivity part operates from -40°C to 85°C, while the Würth substitute operates from -40°C to 125°C. The extended upper temperature limit of the Würth part provides additional thermal margin for applications in elevated ambient conditions or high-power circuit environments.
