TE Connectivity 3-2176075-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 3-2176075-3 is a 3.3 nH unshielded thin film inductor rated for 150 mA maximum current with 1 Ohm maximum DC resistance in a 0201 (0603 Metric) surface mount package. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain electrical performance across critical parameters including inductance value, current rating, DC resistance, and frequency characteristics while meeting the same package and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 3-2176075-3 is determined by strict alignment with the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 3.3 nH (tolerance variations acceptable within design margin)
• Current rating: minimum 150 mA
• DC resistance: maximum 1 Ohm
• Package: 0201 (0603 Metric) surface mount
• Shielding: Unshielded configuration
• Compliance: ROHS3 compliant, MSL 1

Secondary Compatibility Factors:

• Self resonant frequency: 6 GHz or higher
• Q factor at test frequency: 8 or higher preferred
• Operating temperature range: alignment with application requirements
• Mounting compatibility: surface mount tape and reel packaging

The identified substitute parts meet the primary electrical and mechanical criteria, enabling direct functional replacement in circuit applications designed for the original component.

Parameter Comparison

Engineering Selection Recommendations

Würth Elektronik 744900033 is the primary substitute for the TE Connectivity 3-2176075-3. This part maintains identical electrical specifications across inductance, current rating, DC resistance, Q factor, and self resonant frequency. The component carries active product status with established supply availability (10222 pieces in stock). Operating temperature range of -40°C to 125°C and ROHS3 compliance align with the original part requirements. Tape and reel packaging supports automated assembly processes.

TDK MLK0603L3N3ST000 serves as an alternative substitute with enhanced electrical performance characteristics. The multilayer construction delivers superior current rating (200 mA versus 150 mA) and lower DC resistance (400 mOhm maximum versus 1 Ohm maximum), providing design margin for applications requiring improved efficiency. The higher self resonant frequency (8 GHz) and extended operating temperature range (-55°C to 125°C) accommodate demanding environments. However, the component carries Last Time Buy status, indicating limited future availability. Inductance tolerance widens to ±0.3 nH, and seated height increases to 0.013 inches, requiring verification of PCB layout constraints.

Both substitute parts maintain the 0201 (0603 Metric) package footprint, enabling direct PCB placement compatibility. Selection between alternatives depends on application-specific requirements for current margin, DC resistance performance, and long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 744900033 directly replace the TE Connectivity 3-2176075-3 in existing designs?

A: Yes. The Würth Elektronik 744900033 maintains identical inductance (3.3 nH), current rating (150 mA), DC resistance (1 Ohm maximum), and Q factor (8 @ 500 MHz) specifications. The 0201 (0603 Metric) package dimensions and surface mount configuration are identical, enabling direct PCB substitution without layout modification.

Q: What are the key differences between the Würth Elektronik and TDK substitute options?

A: The Würth Elektronik 744900033 provides electrical equivalence with active product status. The TDK MLK0603L3N3ST000 offers enhanced performance through lower DC resistance (400 mOhm versus 1 Ohm) and higher current rating (200 mA versus 150 mA), but carries Last Time Buy status. The TDK component also exhibits slightly increased seated height (0.013 inches versus 0.011 inches) and wider inductance tolerance (±0.3 nH versus ±0.2 nH).

Q: Are there height constraints when substituting with the TDK MLK0603L3N3ST000?

A: The TDK component maximum seated height is 0.013 inches (0.33mm) compared to 0.011 inches (0.28mm) for the original part. PCB layout clearance must accommodate this 0.002-inch (0.05mm) height difference to prevent mechanical interference with adjacent components or solder mask features.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. Both the Würth Elektronik 744900033 and TDK MLK0603L3N3ST000 are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original TE Connectivity component compliance profile.

Q: What is the significance of product status (Active versus Last Time Buy) for component selection?

A: Active status indicates ongoing production and established long-term supply availability. Last Time Buy status signals that production will cease after a specified date, with no future replenishment. For new designs requiring extended production lifecycles, the active Würth Elektronik 744900033 provides supply continuity assurance.

Q: Can the inductance tolerance difference (±0.2 nH versus ±0.3 nH) affect circuit performance?

A: Tolerance impact depends on circuit application sensitivity to inductance variation. For RF and high-frequency applications with tight impedance matching requirements, the tighter ±0.2 nH tolerance of the Würth Elektronik part provides superior performance consistency. For general-purpose filtering and coupling applications, the ±0.3 nH tolerance of the TDK part remains acceptable.

Q: Are the substitute parts available in tape and reel packaging for automated assembly?

A: Yes. Both the Würth Elektronik 744900033 and TDK MLK0603L3N3ST000 are supplied in Tape & Reel (TR) packaging, supporting high-volume automated pick-and-place assembly processes.
