Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 3-2176075-1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 3.1 nH (tolerance variations acceptable within design margin)
• Package format: 0201 (0603 Metric) surface mount
• Shielding configuration: Unshielded
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)

Acceptable Parameter Variations:

• Current rating: Substitute must equal or exceed 150 mA minimum
• DC resistance: Substitute must equal or be lower than 1 Ohm maximum
• Q factor and self-resonant frequency: Substitute values may differ provided inductance and impedance characteristics remain within circuit tolerance
• Inductor type: Thin film and multilayer constructions are functionally equivalent at this inductance value and frequency range
• Operating temperature range: Substitute must support intended application environment

The Shenzhen Sunlord Electronics SDCL0603Q3N1BT02B03 meets all mandatory matching parameters and exceeds performance specifications in current rating and DC resistance, qualifying it as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The Shenzhen Sunlord Electronics SDCL0603Q3N1BT02B03 is qualified as a direct substitute for the obsolete TE Connectivity 3-2176075-1 based on the following engineering criteria:

Electrical Compatibility: The substitute part maintains identical inductance value (3.1 nH) with improved tolerance specification (±0.1 nH versus ±0.2 nH). Current rating is increased from 150 mA to 450 mA, providing design margin for thermal and electrical stress. DC resistance is reduced from 1 Ohm maximum to 250 mOhm maximum, resulting in lower power dissipation and improved circuit efficiency. Q factor improvement from 8 to 13 at 500 MHz indicates superior frequency response characteristics.

Physical Compatibility: Both components utilize identical 0201 (0603 Metric) surface mount packaging with matching footprint dimensions (0.024" L x 0.012" W). Height difference of 0.002" (0.05mm) is negligible for standard PCB assembly processes and does not impact board-level integration.

Compliance and Supply Status: The substitute part carries active product status, ensuring long-term availability and supply chain continuity. Both components maintain MSL 1 (Unlimited) moisture sensitivity rating, eliminating special handling requirements. The original part's ROHS3 compliance is maintained through the substitute's compliance with equivalent environmental standards.

Application Suitability: The multilayer ceramic core construction of the substitute provides stable performance across the specified operating temperature range (-55°C to 125°C), supporting applications requiring extended thermal operation. The improved self-resonant frequency (8.5 GHz versus 6 GHz) extends usable frequency bandwidth for high-speed circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the Sunlord SDCL0603Q3N1BT02B03 be used as a direct replacement for the TE Connectivity 3-2176075-1 in existing designs?

A: Yes. Both components share identical inductance value (3.1 nH), package format (0201/0603 Metric), and physical footprint dimensions. The substitute meets or exceeds all electrical specifications of the original part. PCB layout and assembly processes require no modification.

Q: What is the significance of the reduced DC resistance in the substitute part?

A: The substitute's DC resistance of 250 mOhm maximum compared to the original 1 Ohm maximum represents a 75% reduction in series resistance. This directly reduces power dissipation (I²R losses) in the inductor, improving overall circuit efficiency and reducing thermal stress on the component and surrounding circuitry.

Q: Does the difference in inductor type (thin film versus multilayer) affect circuit performance?

A: At 3.1 nH inductance and the specified frequency range (500 MHz test frequency, 6-8.5 GHz self-resonant frequency), both thin film and multilayer ceramic constructions deliver equivalent inductance and impedance characteristics. The multilayer ceramic construction of the substitute provides improved Q factor (13 versus 8), indicating lower losses and better frequency response.

Q: Are there any height clearance concerns with the substitute part?

A: The substitute part height is 0.013" (0.33mm) maximum compared to 0.011" (0.28mm) for the original part, representing a 0.002" (0.05mm) increase. This difference is within standard PCB assembly tolerances and does not impact component placement, solder joint formation, or board-level clearance requirements for typical applications.

Q: What is the operating temperature range for the substitute part?

A: The Sunlord SDCL0603Q3N1BT02B03 operates across -55°C to 125°C. This range covers standard industrial and extended commercial temperature requirements. Verify that this range meets your specific application requirements.

Q: How does the improved Q factor of the substitute part benefit circuit design?

A: Q factor of 13 at 500 MHz (versus 8 for the original) indicates lower energy dissipation and sharper frequency selectivity. This results in improved filter performance, reduced insertion loss in RF/microwave circuits, and better impedance matching characteristics in high-frequency applications.

Q: Is the substitute part available in tape and reel packaging?

A: Yes. The Sunlord SDCL0603Q3N1BT02B03 is supplied in Tape & Reel (TR) packaging format, suitable for automated PCB assembly processes. Inventory availability is 15,822 pieces in new original condition.

Q: Are moisture sensitivity precautions required for the substitute part?

A: No. Both the original and substitute parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity. Standard handling and storage procedures apply without special desiccant or humidity-controlled environment requirements.
