Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 4-2176075-1 is based on the following critical parameters:

Inductance Value: The substitute part must operate within the tolerance band of the original specification. The 4-2176075-1 specifies 4.4 nH ±0.2 nH, establishing an acceptable range of 4.2 nH to 4.6 nH.

Package Compatibility: Both the main part and substitute must use identical 0201 (0603 Metric) surface mount packaging to ensure PCB layout compatibility and assembly process alignment.

Shielding Configuration: The unshielded design of the original part establishes the electromagnetic environment for which the circuit was designed. Substitute parts must maintain unshielded construction.

Physical Dimensions: The footprint and height specifications must match to prevent assembly interference and maintain design intent for high-frequency applications.

Compliance Standards: RoHS3 compliance and MSL rating must be maintained to satisfy regulatory and manufacturing requirements.

The TDK Corporation MLK0603L4N3ST000 meets these substitution criteria with a 4.3 nH inductance value (within the acceptable tolerance band), identical 0201 package, unshielded construction, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TDK Corporation MLK0603L4N3ST000 is the qualified substitute for the obsolete TE Connectivity 4-2176075-1 based on the following engineering criteria:

Inductance Compatibility: The 4.3 nH value of the TDK part falls within the acceptable tolerance band established by the original 4.4 nH ±0.2 nH specification, ensuring functional equivalence in circuit operation.

Package and Footprint Alignment: Both components utilize identical 0201 (0603 Metric) surface mount packaging with matching lateral dimensions (0.024" L x 0.012" W). The height difference of 0.002" (0.33mm vs 0.28mm) is within typical PCB assembly clearance margins and does not preclude direct substitution.

Compliance Certification: Both parts maintain ROHS3 compliance and MSL Level 1 rating, satisfying regulatory requirements and manufacturing process compatibility.

Availability Status: The substitute part is designated as Last Time Buy with significantly higher inventory availability (18,533 pcs vs 1,583 pcs), providing extended procurement window for design transitions.

Unshielded Configuration: The maintained unshielded design ensures electromagnetic behavior consistency with the original circuit design intent.

Frequently Asked Questions (FAQ)

Q: Can the TDK MLK0603L4N3ST000 be used as a direct replacement for the TE Connectivity 4-2176075-1?

A: Yes. Both components share identical 0201 (0603 Metric) surface mount packaging, unshielded construction, and the 4.3 nH inductance value of the TDK part falls within the acceptable tolerance band of the original 4.4 nH ±0.2 nH specification.

Q: What is the significance of the 0.002" height difference between these parts?

A: The TDK substitute has a maximum seated height of 0.013" compared to 0.011" for the original part. This 0.002" difference is negligible for standard PCB assembly and does not impact component placement or clearance in typical circuit designs.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent regulatory and manufacturing process compatibility.

Q: Why is the inductance tolerance of the substitute part wider (±0.3 nH vs ±0.2 nH)?

A: The TDK part uses multilayer construction technology, which has inherent tolerance characteristics different from the thin film construction of the original part. The 4.3 nH nominal value with ±0.3 nH tolerance still maintains overlap with the original specification band, ensuring functional compatibility.

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

A: Thin film inductors use deposited film technology on a substrate, while multilayer inductors use stacked ceramic layers with embedded conductors. Both technologies achieve the required inductance value in the 0201 package format. The multilayer construction of the substitute part provides additional current handling capability (200 mA) and defined DC resistance (500 mOhm Max).

Q: Is the packaging format (Tape & Reel vs Cut Tape) significant for substitution?

A: Packaging format affects procurement and assembly logistics but does not impact electrical or mechanical compatibility. The TDK part is supplied in Tape & Reel format, which is standard for high-volume production environments and may offer cost advantages over Cut Tape packaging.

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

A: Last Time Buy status indicates the manufacturer has announced end-of-life for this component. While currently available in substantial inventory (18,533 pcs), procurement should be planned accordingly for long-term production requirements.
