Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2-2176086-4 is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 15 nH with ±5% tolerance
• Unshielded configuration
• Surface mount technology
• RoHS3 compliance
• MSL 1 rating

Secondary Compatibility Factors:

• Current rating capability (minimum 1.1 A required for direct substitution)
• DC resistance characteristics
• Self-resonant frequency performance
• Operating temperature range coverage

The TDK Corporation MLK1005S15NJT000 shares the core inductance specification and unshielded topology. However, this substitute exhibits reduced current rating (300 mA versus 1.1 A) and elevated DC resistance (500 mOhm versus 110 mOhm), indicating application-dependent compatibility rather than direct equivalence.

Engineering Selection Recommendations

TE Connectivity 2-2176086-4 (Obsolete): This wirewound inductor is no longer in production. Existing inventory of 977 pieces is available through current stock channels. The part maintains full RoHS3 compliance and REACH unaffected status. Applications currently utilizing this component require transition planning to alternative sources.

TDK MLK1005S15NJT000 (Last Time Buy): The TDK substitute provides matching inductance and tolerance specifications with extended lower temperature operating range (-55°C versus -40°C minimum). This multilayer inductor is available in standard 0402 (1005 Metric) packaging with significantly higher inventory (10,100 pieces). The part is RoHS3 compliant and REACH unaffected.

Critical Substitution Limitations: The TDK MLK1005S15NJT000 exhibits current rating of 300 mA, representing a 73% reduction from the TE Connectivity specification of 1.1 A. DC resistance increases from 110 mOhm to 500 mOhm maximum. These parameter differences restrict substitution to applications where current demand does not exceed 300 mA and where increased resistive losses are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the TDK MLK1005S15NJT000 directly replace the TE Connectivity 2-2176086-4 in all applications?

A: No. While both components share identical 15 nH inductance and ±5% tolerance, the TDK substitute is rated for 300 mA maximum current compared to 1.1 A for the TE Connectivity part. Substitution is valid only for circuits where current demand does not exceed 300 mA.

Q: What is the impact of the increased DC resistance in the TDK substitute?

A: The TDK MLK1005S15NJT000 exhibits 500 mOhm maximum DC resistance versus 110 mOhm for the TE Connectivity 2-2176086-4. This 4.5-fold increase results in higher resistive losses and heat dissipation. Applications sensitive to insertion loss or thermal performance require evaluation of this parameter change.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the TE Connectivity 2-2176086-4 and TDK MLK1005S15NJT000 are RoHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the packaging difference between these components?

A: The TE Connectivity 2-2176086-4 uses nonstandard packaging (0.045" L x 0.028" W / 1.15mm x 0.70mm). The TDK MLK1005S15NJT000 uses standard 0402 (1005 Metric) packaging (0.039" L x 0.020" W / 1.00mm x 0.50mm). PCB layout modifications are required for substitution.

Q: Does the TDK substitute offer any performance advantages?

A: The TDK MLK1005S15NJT000 provides extended lower temperature operation (-55°C minimum versus -40°C) and higher self-resonant frequency (4 GHz versus 3.9 GHz). Standard 0402 packaging offers improved availability and supply chain stability.

Q: What is the product status of each component?

A: The TE Connectivity 2-2176086-4 is classified as obsolete. The TDK MLK1005S15NJT000 is designated as Last Time Buy, indicating limited future availability.
