TE Connectivity 1-2176075-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-2176075-2 is a 1.2 nH unshielded thin film inductor rated for 300 mA with a maximum DC resistance of 350 mOhm 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, and frequency characteristics while meeting the same packaging and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1-2176075-2 is determined by strict equivalence across the following parameters:

Primary Electrical Parameters:

• Inductance value: 1.2 nH
• Current rating: 300 mA minimum
• Package / Case: 0201 (0603 Metric)
• Mounting type: Surface Mount
• Shielding configuration: Unshielded

Secondary Electrical Parameters:

• DC resistance within acceptable operating limits
• Self resonant frequency suitable for intended frequency range
• Q factor performance at specified test frequency

Compliance & Environmental Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 1
• Tape & Reel packaging format

Two substitute parts meet these criteria with variations in construction type and DC resistance characteristics. The Würth Elektronik 744900012 maintains identical electrical specifications with active product status. The TDK Corporation MLK0603L1N2ST000 provides equivalent inductance and current rating with improved DC resistance (220 mOhm vs. 350 mOhm) but operates under Last Time Buy status.

Parameter Comparison

Engineering Selection Recommendations

Würth Elektronik 744900012 is the primary substitute for new designs and production transitions. This part maintains identical electrical specifications to the obsolete TE Connectivity component, including inductance tolerance (±0.2 nH), DC resistance (350 mOhm), and Q factor (8 @ 500MHz). The Würth part carries active product status with established supply chain availability (10,912 pcs in stock). Operating temperature range (-40°C ~ 125°C) is specified and suitable for standard industrial applications. RoHS3 compliance and MSL 1 rating match the original component.

TDK Corporation MLK0603L1N2ST000 serves as an alternative substitute with enhanced DC resistance performance (220 mOhm vs. 350 mOhm), resulting in lower power dissipation. This multilayer construction inductor operates under Last Time Buy status, indicating limited future availability. The inductance tolerance is wider (±0.3 nH vs. ±0.2 nH), and the Q factor is measured at a different frequency (6 @ 300MHz vs. 8 @ 500MHz). Extended operating temperature range (-55°C ~ 125°C) provides additional thermal margin. Selection of the TDK part requires confirmation that the wider tolerance and different construction type are acceptable for the specific application.

Both substitute parts satisfy RoHS3 compliance, MSL 1 moisture sensitivity, and identical physical package dimensions. Component selection should prioritize the Würth Elektronik part for long-term supply security and specification alignment.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 744900012 directly replace the TE Connectivity 1-2176075-2?

A: Yes. Both parts share identical inductance (1.2 nH), inductance tolerance (±0.2 nH), current rating (300 mA), DC resistance (350 mOhm), Q factor (8 @ 500MHz), self resonant frequency (9 GHz), package (0201 / 0603 Metric), and compliance certifications (RoHS3, MSL 1). The Würth part is actively manufactured and available.

Q: What are the differences between the TDK MLK0603L1N2ST000 and the original TE part?

A: The TDK part uses multilayer construction instead of thin film, resulting in lower DC resistance (220 mOhm vs. 350 mOhm). Inductance tolerance is ±0.3 nH (vs. ±0.2 nH), Q factor is measured at 300MHz (vs. 500MHz), and self resonant frequency is 11 GHz (vs. 9 GHz). Operating temperature range extends to -55°C. The TDK part is under Last Time Buy status.

Q: Are all three parts physically identical in size?

A: Yes. All three inductors use the 0201 (0603 Metric) package with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm). Height specifications are 0.011" (0.28mm) for the Würth part and 0.013" (0.33mm) for the TDK part, both within standard PCB assembly tolerances.

Q: Which substitute part should be selected for new production designs?

A: The Würth Elektronik 744900012 is recommended for new designs. It maintains complete electrical and compliance equivalence to the obsolete TE part and carries active product status with established supply availability.

Q: Can the TDK part be used if lower DC resistance is beneficial?

A: The TDK MLK0603L1N2ST000 can be used if the application benefits from reduced DC resistance (220 mOhm vs. 350 mOhm) and extended temperature range (-55°C ~ 125°C). However, the wider inductance tolerance (±0.3 nH) and Last Time Buy status require evaluation against design requirements and supply chain strategy.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The TE Connectivity 1-2176075-2, Würth Elektronik 744900012, and TDK MLK0603L1N2ST000 are all RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference between thin film and multilayer inductor construction?

A: Thin film inductors (TE and Würth parts) use deposited film technology, while multilayer inductors (TDK part) use stacked ceramic layers. The TDK multilayer construction achieves lower DC resistance but operates under Last Time Buy status. Both construction types meet the specified electrical parameters for this 1.2 nH application.
