TE Connectivity 2-2176075-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-2176075-2 is a 2.2 nH unshielded thin film inductor rated for 200 mA maximum current with 700 mOhm 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 the specified inductance, current rating, and impedance parameters while meeting RoHS3 compliance and moisture sensitivity requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 2-2176075-2 is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 2.2 nH
• Package / Case: 0201 (0603 Metric) surface mount
• Shielding configuration: Unshielded
• Mounting type: Surface mount

Secondary Compatibility Parameters:

• Current rating: Minimum 200 mA
• DC resistance: Maximum 700 mOhm
• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

Parts meeting all primary criteria and secondary parameters are classified as direct substitutes. Parts exceeding current rating or providing lower DC resistance offer enhanced performance margins. Variations in inductance tolerance, Q factor, or self-resonant frequency do not disqualify substitution when the primary inductance value and package specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Würth Elektronik 744900022 is the primary substitute for the TE Connectivity 2-2176075-2. This part maintains identical electrical specifications across inductance value, tolerance, current rating, and DC resistance. The component is active status, ensuring long-term availability and supply chain continuity. Both parts share thin film construction, identical Q factor at 500 MHz, and matching self-resonant frequency. RoHS3 compliance and MSL 1 rating are equivalent. The Würth part provides defined operating temperature range (-40°C ~ 125°C) and higher inventory availability (10989 units).

TDK MLK0603L2N2ST000 functions as a secondary substitute with performance enhancements. This multilayer inductor maintains the 2.2 nH inductance value and 0201 package specification. The part exceeds the original current rating (300 mA versus 200 mA) and provides superior DC resistance performance (300 mOhm maximum versus 700 mOhm maximum). Inductance tolerance is wider (±0.3 nH versus ±0.2 nH). The TDK part operates across an extended temperature range (-55°C ~ 125°C) and achieves higher self-resonant frequency (9 GHz). However, this part carries Last Time Buy status, limiting future procurement options. The multilayer construction differs from the original thin film design, and Q factor measurement frequency differs (300 MHz versus 500 MHz).

Selection between the Würth and TDK substitutes depends on design requirements. The Würth part provides direct electrical and construction equivalence with active status. The TDK part offers enhanced current handling and lower resistance at the cost of reduced tolerance precision and limited availability.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 744900022 directly replace the TE Connectivity 2-2176075-2 without circuit modification?

A: Yes. The Würth part maintains identical inductance (2.2 nH), tolerance (±0.2 nH), current rating (200 mA), DC resistance (700 mOhm maximum), and package specification (0201 / 0603 Metric). Both components are unshielded thin film inductors with matching Q factor (8 @ 500MHz) and self-resonant frequency (8 GHz). No circuit redesign is required.

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

A: The Würth 744900022 provides direct electrical equivalence with active product status. The TDK MLK0603L2N2ST000 offers enhanced performance (300 mA current rating, 300 mOhm DC resistance) but uses multilayer construction instead of thin film, carries Last Time Buy status, and has wider inductance tolerance (±0.3 nH). The TDK part is suitable for designs requiring higher current margins or lower resistance; the Würth part is recommended for direct replacement and long-term supply assurance.

Q: Are packaging formats interchangeable between these parts?

A: All three parts use identical 0201 (0603 Metric) surface mount packages with matching footprints and mounting requirements. The TE part is supplied in Cut Tape and Digi-Reel format; both substitutes are supplied in Tape & Reel format. Tape & Reel packaging is standard for automated assembly processes and is compatible with existing pick-and-place equipment.

Q: Do all parts meet the same compliance standards?

A: Yes. The TE Connectivity 2-2176075-2, Würth Elektronik 744900022, and TDK MLK0603L2N2ST000 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All parts carry EAR99 ECCN classification. The Würth part specifies REACH Unaffected status; the TDK part specifies REACH Unaffected status. Compliance requirements are met across all three options.

Q: What is the significance of the "Last Time Buy" status for the TDK part?

A: Last Time Buy status indicates that TDK will discontinue the MLK0603L2N2ST000 after a specified date. Existing inventory (2094 units) represents the final available supply. This part is suitable for current production runs but not recommended for new long-term designs. The Würth Elektronik 744900022, with Active status, is the preferred choice for designs requiring extended production life.

Q: How do inductance tolerance differences affect circuit performance?

A: The TE and Würth parts specify ±0.2 nH tolerance; the TDK part specifies ±0.3 nH tolerance. For a 2.2 nH inductor, the TE and Würth parts maintain tolerance within ±9.1% of nominal value; the TDK part tolerance is ±13.6% of nominal value. Applications requiring tighter inductance control should use the TE or Würth parts. Applications with broader tolerance margins can accommodate the TDK part.

Q: Can the TDK part be used in applications originally designed for the TE part?

A: The TDK MLK0603L2N2ST000 can be used in most applications, with the following considerations: the part provides superior current handling (300 mA versus 200 mA), lower DC resistance (300 mOhm versus 700 mOhm), and extended temperature range (-55°C ~ 125°C). However, inductance tolerance is wider (±0.3 nH), Q factor is measured at different frequency (300 MHz versus 500 MHz), and construction type differs (multilayer versus thin film). Circuit validation is required for applications with strict inductance tolerance or frequency-dependent performance requirements.
