Substitute Part Grouping Explanation

Substitution of the 36401E2N7ATDF is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Inductance value: 2.7 nH
• Current rating: 440 mA minimum
• DC resistance: 350 mOhm maximum
• Q factor: 13 @ 500 MHz
• Self-resonant frequency: 8 GHz
• Inductor type: Thin film

Mechanical Specifications:

• Package: 0402 (1005 Metric)
• Mounting: Surface mount
• Shielding: Unshielded
• Physical dimensions: 0.039" L × 0.020" W (1.00 mm × 0.50 mm)
• Maximum seated height: 0.015" (0.37 mm)

Compliance & Environmental:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts must meet or exceed all electrical parameters and maintain identical mechanical compatibility. Inductance tolerance may vary within acceptable design margins. Product status and availability are secondary considerations to electrical and mechanical equivalence.

Engineering Selection Recommendations

The ATFC-0402-2N7B-T from Abracon LLC is a direct electrical and mechanical equivalent to the obsolete 36401E2N7ATDF. Both components share identical inductance values, current ratings, DC resistance specifications, Q factors, and self-resonant frequencies. Physical dimensions and package specifications are identical, ensuring PCB layout compatibility without redesign.

The ATFC-0402-2N7B-T offers the following advantages for component selection:

Product Status: The Abracon part maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete TE Connectivity part.

Compliance: Both components are ROHS3 compliant and carry identical moisture sensitivity ratings (MSL 1 - Unlimited), meeting environmental and regulatory requirements.

Inductance Tolerance: The Abracon substitute provides tighter inductance tolerance (±0.1 nH versus ±0.2 nH), which may improve circuit performance in applications requiring precise inductance values.

Operating Temperature Range: The Abracon part specifies an operating temperature range of -45°C to 85°C, providing defined thermal performance parameters absent from the TE Connectivity specification.

Packaging: The Abracon part is supplied in Tape & Reel (TR) format, which is standard for high-volume production environments, whereas the TE Connectivity part is supplied in Cut Tape (CT) format.

Frequently Asked Questions (FAQ)

Q: Can the ATFC-0402-2N7B-T directly replace the 36401E2N7ATDF without circuit modifications?

A: Yes. Both components are electrically and mechanically equivalent. They share identical inductance values (2.7 nH), current ratings (440 mA), DC resistance (350 mOhm max), Q factors (13 @ 500 MHz), and self-resonant frequencies (8 GHz). Physical dimensions and package specifications are identical, requiring no PCB layout changes.

Q: What is the difference in inductance tolerance between these parts?

A: The 36401E2N7ATDF has a tolerance of ±0.2 nH, while the ATFC-0402-2N7B-T has a tolerance of ±0.1 nH. The tighter tolerance of the Abracon part may provide improved circuit performance in applications sensitive to inductance variation.

Q: Are both parts RoHS compliant?

A: Yes. Both the 36401E2N7ATDF and ATFC-0402-2N7B-T are ROHS3 compliant and carry identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: What is the difference in packaging format?

A: The 36401E2N7ATDF is supplied in Cut Tape (CT) format, while the ATFC-0402-2N7B-T is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and high-volume production.

Q: Does the Abracon part have specified operating temperature limits?

A: Yes. The ATFC-0402-2N7B-T specifies an operating temperature range of -45°C to 85°C. The TE Connectivity part does not provide an operating temperature specification in the available data.

Q: Are the physical dimensions identical?

A: Yes. Both components are packaged in the 0402 (1005 Metric) form factor with identical dimensions of 0.039" L × 0.020" W (1.00 mm × 0.50 mm) and maximum seated height of 0.015" (0.37 mm).

Q: Why is the TE Connectivity part listed as obsolete?

A: The 36401E2N7ATDF is classified as obsolete, indicating that TE Connectivity has discontinued production. The Abracon ATFC-0402-2N7B-T maintains active production status, ensuring continued availability for new designs and component replenishment.
