Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2176075-4 is based on the following critical parameters that must remain constant or compatible:

Mandatory Matching Parameters:

• Inductance value: 0.4 nH
• Inductance tolerance: ±0.2 nH
• Package / Case: 0201 (0603 Metric)
• Mounting type: Surface Mount
• Shielding configuration: Unshielded

Compatible Variation Parameters:

• Current rating: Substitute must equal or exceed 350 mA
• DC resistance: Substitute must equal or be lower than 250 mOhm
• Self-resonant frequency: Substitute must equal or exceed 9 GHz
• RoHS and MSL compliance: Substitute must maintain or exceed compliance level

The TDK Corporation MLG0603S0N4CT000 satisfies all mandatory matching parameters and exceeds performance in current rating (600 mA vs. 350 mA) and DC resistance (100 mOhm vs. 250 mOhm), making it a direct functional substitute.

Engineering Selection Recommendations

The TDK Corporation MLG0603S0N4CT000 is the qualified substitute for the obsolete TE Connectivity 2176075-4. Selection is based on the following engineering criteria:

Compliance and Certification: Both components maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with current manufacturing and environmental standards.

Product Status: The TE Connectivity 2176075-4 is classified as obsolete, creating supply chain risk. The TDK MLG0603S0N4CT000 is active production status with confirmed inventory availability (8771 pieces), providing long-term supply continuity.

Electrical Performance: The substitute part meets or exceeds all critical electrical parameters. The identical inductance value (0.4 nH) and tolerance (±0.2 nH) ensure circuit performance equivalence. The improved current rating (600 mA vs. 350 mA) and reduced DC resistance (100 mOhm vs. 250 mOhm) provide enhanced thermal and electrical performance margins.

Physical Compatibility: Both components share identical package dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) and mounting type (Surface Mount 0201), enabling direct board-level substitution without layout modification.

Packaging Consideration: The main part is supplied in Cut Tape (CT) & Digi-Reel® packaging, while the substitute is supplied in Tape & Reel (TR) format. Both formats are standard for surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the TDK MLG0603S0N4CT000 be used as a direct replacement for the TE Connectivity 2176075-4?

A: Yes. Both components have identical inductance (0.4 nH), inductance tolerance (±0.2 nH), package type (0201 / 0603 Metric), and mounting configuration (Surface Mount). The substitute meets or exceeds all electrical performance requirements.

Q: What are the key differences between these two inductors?

A: The primary differences are manufacturer (TE Connectivity vs. TDK), inductor type (Thin Film vs. Multilayer), product status (Obsolete vs. Active), and performance specifications. The TDK part provides superior current handling (600 mA vs. 350 mA) and lower DC resistance (100 mOhm vs. 250 mOhm).

Q: Are there any compatibility issues with PCB assembly?

A: No. Both components use identical 0201 (0603 Metric) surface mount packages with matching physical dimensions. Standard pick-and-place and reflow assembly processes are compatible with both parts.

Q: Does the substitute part meet the same compliance standards?

A: Yes. Both the TE Connectivity 2176075-4 and TDK MLG0603S0N4CT000 are ROHS3 compliant and rated MSL Level 1 (Unlimited). Both carry EAR99 ECCN classification and identical HTSUS code (8504.50.8000).

Q: What is the impact of the different inductor types (Thin Film vs. Multilayer)?

A: Both inductor types achieve the specified 0.4 nH inductance with ±0.2 nH tolerance. The multilayer construction of the TDK part provides improved current handling capacity and lower DC resistance, resulting in reduced power dissipation in the application circuit.

Q: Is the packaging format difference (Cut Tape vs. Tape & Reel) significant?

A: Both packaging formats are standard for surface mount component assembly. Cut Tape (CT) is suitable for manual or small-volume assembly, while Tape & Reel (TR) is optimized for high-volume automated assembly. Selection depends on production volume and assembly equipment capability.

Q: What is the self-resonant frequency difference, and does it matter?

A: The TE Connectivity part has a self-resonant frequency of 9 GHz, while the TDK substitute is 10 GHz. Both frequencies are well above typical RF and high-speed digital circuit operating ranges, ensuring stable inductor behavior across the intended application bandwidth.
