36401E1N2ATDF Equivalent & Substitute Parts

Part Overview

The 36401E1N2ATDF is a 1.2 nH unshielded thin film surface mount inductor manufactured by TE Connectivity Passive Product. This component is rated for 700 mA continuous current with a maximum DC resistance of 150 mOhm and operates at a self-resonant frequency of 12 GHz. The part is packaged in the 0402 (1005 Metric) form factor and is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, identifying equivalent substitute components is necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 36401E1N2ATDF is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value: 1.2 nH
• Current rating: 700 mA minimum
• DC resistance: 150 mOhm maximum
• Q factor: 13 @ 500 MHz
• Self-resonant frequency: 12 GHz

Mechanical & Package Parameters:

• Package / Case: 0402 (1005 Metric)
• Mounting type: Surface Mount
• Shielding configuration: Unshielded
• Component type: Thin Film inductor

Compliance & Environmental Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must meet or exceed all specified electrical ratings and maintain identical mechanical compatibility. Inductance tolerance, while differing between the main part and substitute, remains within acceptable design margins for high-frequency applications when the nominal inductance value is preserved.

Engineering Selection Recommendations

The ATFC-0402-1N2B-T from Abracon LLC is a direct electrical and mechanical equivalent to the obsolete 36401E1N2ATDF. Selection of this substitute is supported by the following factors:

Product Status: The ATFC-0402-1N2B-T maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete 36401E1N2ATDF.

Electrical Equivalence: All critical electrical parameters—inductance, current rating, DC resistance, Q factor, and self-resonant frequency—are identical between the two components. The substitute exhibits a tighter inductance tolerance (±0.1 nH versus ±0.2 nH), which provides improved consistency in high-frequency circuit performance.

Mechanical Compatibility: Both components share identical package dimensions (0402 / 1005 Metric), mounting type (Surface Mount), and physical footprint, enabling direct board-level substitution without layout modification.

Compliance & Environmental: Both parts meet ROHS3 compliance requirements and carry Moisture Sensitivity Level 1 (Unlimited), ensuring equivalent environmental robustness. The substitute provides an explicit operating temperature range (-45°C ~ 85°C), whereas the main part does not specify this parameter.

Packaging Consideration: The main part is supplied in Cut Tape (CT) packaging, while the substitute is supplied in Tape & Reel (TR) format. This difference reflects standard industry practice for active versus obsolete components and does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the ATFC-0402-1N2B-T be used as a direct replacement for the 36401E1N2ATDF in existing designs?

A: Yes. The ATFC-0402-1N2B-T meets all electrical and mechanical specifications of the 36401E1N2ATDF. Both components are 1.2 nH thin film inductors rated for 700 mA with 150 mOhm maximum DC resistance, packaged in 0402 (1005 Metric) form factor. No circuit redesign or board layout modification is required.

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

A: The 36401E1N2ATDF specifies ±0.2 nH tolerance, while the ATFC-0402-1N2B-T specifies ±0.1 nH tolerance. The substitute provides tighter tolerance control, which may improve circuit performance consistency in high-frequency applications where inductance precision is critical.

Q: Are there packaging differences between these components?

A: Yes. The 36401E1N2ATDF is supplied in Cut Tape (CT) packaging, while the ATFC-0402-1N2B-T is supplied in Tape & Reel (TR) packaging. Both formats are compatible with standard surface mount assembly equipment. The packaging difference reflects the active production status of the substitute component.

Q: Do both components meet the same compliance standards?

A: Yes. Both the 36401E1N2ATDF and ATFC-0402-1N2B-T are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited). Both are classified under ECCN EAR99 and HTSUS 8504.50.8000.

Q: What is the operating temperature range for these inductors?

A: The ATFC-0402-1N2B-T specifies an operating temperature range of -45°C to 85°C. The 36401E1N2ATDF does not provide an explicit operating temperature specification in the available documentation.

Q: Are these components suitable for high-frequency applications?

A: Yes. Both inductors are designed for high-frequency operation with a self-resonant frequency of 12 GHz and a Q factor of 13 at 500 MHz, making them suitable for RF and microwave circuit applications in the gigahertz frequency range.

Q: Can these 0402 inductors be hand-soldered?

A: The 0402 (1005 Metric) package is a surface mount component designed for reflow soldering in automated assembly processes. Hand soldering of 0402 components is not recommended due to the small form factor and risk of thermal damage to the component.
