Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 3-2176075-2 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 3.2 nH
• Package format: 0201 (0603 Metric) surface mount
• Shielding configuration: Unshielded
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)

Allowable Variation Parameters:

• Current rating must equal or exceed 150 mA
• DC resistance must not exceed 1 Ohm maximum
• Inductance tolerance must be ±0.2 nH or tighter
• Self-resonant frequency must be 6 GHz or higher
• Q factor at 500 MHz must be 8 or higher

The Pulse Electronics BSPQ000603043N2B00 satisfies all mandatory matching parameters and exceeds allowable variation thresholds, qualifying it as a direct substitute.

Engineering Selection Recommendations

The Pulse Electronics BSPQ000603043N2B00 is a qualified substitute for the obsolete TE Connectivity 3-2176075-2 based on the following engineering criteria:

Compliance and Availability: The substitute part maintains ROHS3 compliance and MSL 1 rating, ensuring regulatory alignment with the original component. The substitute is currently in active production status with confirmed inventory availability, addressing the obsolescence constraint of the original part.

Electrical Performance: The substitute part delivers superior electrical characteristics across all measured parameters. DC resistance is reduced to 170 mOhm maximum compared to 1 Ohm maximum, resulting in lower power dissipation. Quality factor at 500 MHz increases from 8 to 20, indicating improved efficiency at the test frequency. Self-resonant frequency increases from 6 GHz to 7 GHz, extending the usable frequency range.

Current Capacity: The substitute part is rated for 500 mA maximum current, exceeding the original 150 mA specification by a factor of 3.33. This provides additional design margin for applications requiring higher current handling.

Physical Compatibility: Footprint dimensions remain identical at 0.024" L x 0.012" W (0.60mm x 0.30mm), ensuring direct PCB layout compatibility. Seated height increases from 0.011" (0.28mm) to 0.017" (0.43mm), a difference of 0.006" (0.15mm) that does not impact standard surface mount assembly processes or clearance requirements in typical applications.

Inductance Specification: Both parts maintain 3.2 nH inductance at 500 MHz test frequency. The substitute part offers tighter tolerance at ±0.1 nH compared to ±0.2 nH, providing improved consistency for precision circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the Pulse Electronics BSPQ000603043N2B00 be used as a direct replacement in existing designs using the TE Connectivity 3-2176075-2?

A: Yes. The substitute part matches all mandatory electrical and mechanical parameters. Identical inductance value, package format, and footprint dimensions enable direct PCB substitution. The increased seated height of 0.006" (0.15mm) does not affect standard assembly or clearance in typical applications.

Q: What are the key differences between the original and substitute parts?

A: The substitute part features lower DC resistance (170 mOhm vs. 1 Ohm), higher current rating (500 mA vs. 150 mA), higher Q factor (20 vs. 8 at 500 MHz), and higher self-resonant frequency (7 GHz vs. 6 GHz). These represent performance improvements rather than deviations from the original specification.

Q: Are there any material or construction differences between these parts?

A: The original TE Connectivity part is a thin film inductor, while the substitute Pulse Electronics part is a thick film inductor with ceramic core material. Both are unshielded and maintain identical electrical performance at the specified test frequency of 500 MHz.

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

A: Yes. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. The substitute part carries REACH Unaffected status, confirming regulatory alignment.

Q: What is the impact of the increased seated height on PCB assembly?

A: The seated height increase from 0.011" (0.28mm) to 0.017" (0.43mm) represents a 0.006" (0.15mm) difference. This does not impact standard surface mount assembly processes, reflow profiles, or clearance requirements in typical circuit board designs.

Q: Is the substitute part available in the same packaging format?

A: The substitute part is supplied in Tape & Reel (TR) packaging, while the original part packaging format was not specified in the available data. Both parts use identical 0201 (0603 Metric) component package format suitable for automated assembly equipment.

Q: How does the tighter inductance tolerance of the substitute part affect circuit performance?

A: The substitute part tolerance of ±0.1 nH is tighter than the original ±0.2 nH specification. This provides improved consistency and reduced variation in inductance values across production batches, beneficial for precision applications requiring tight component tolerances.
