SWPA3010S2R2NT Equivalent & Substitute Parts

Part Overview

The SWPA3010S2R2NT is a 2.2 µH shielded drum core wirewound inductor manufactured by Shenzhen Sunlord Electronics Co., Ltd. This surface mount component is rated for 1.09 A continuous current with a maximum DC resistance of 143 mOhm and operates across the temperature range of -40°C to 125°C. The part is currently active in production with substantial inventory availability.

Substitute parts are identified when equivalent inductance values, current ratings, shielding characteristics, and physical dimensions align within acceptable engineering tolerances. Alternative sources provide equivalent electrical performance while maintaining compatibility with existing PCB layouts and thermal requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the SWPA3010S2R2NT is determined by the following critical parameters:

Inductance Value: The substitute part must maintain 2.2 µH inductance. Tolerance variations between ±30% (SWPA3010S2R2NT) and ±20% (BWVF003030102R2M00) are acceptable as both specifications encompass the nominal value.

Current Rating: The substitute must support the application's current requirements. The SWPA3010S2R2NT operates at 1.09 A continuous current; substitute parts with equal or higher current ratings are acceptable.

DC Resistance: Lower DC resistance in substitute parts reduces power dissipation and heat generation. The SWPA3010S2R2NT specifies 143 mOhm maximum; substitutes with 100 mOhm provide improved performance characteristics.

Shielding: Both the main part and substitute must be shielded to maintain electromagnetic compatibility and prevent interference in sensitive circuits.

Physical Dimensions: The package footprint (3.00 x 3.00 mm) and height (1.00 mm nominal) must remain consistent for PCB layout compatibility.

Core Material: Ferrite core construction is maintained across all qualified substitutes.

Mounting Type: Surface mount technology is required for both main and substitute parts.

Engineering Selection Recommendations

Primary Selection (SWPA3010S2R2NT): Use when Shenzhen Sunlord Electronics supply chain is established and inventory availability is prioritized. This part is active in production with 21,400 units in stock.

Substitute Selection (BWVF003030102R2M00): Use when the following conditions apply:

Supply Chain Diversification: Pulse Electronics sourcing is preferred to reduce single-manufacturer dependency.
Improved Performance Margin: The substitute provides 28% higher current rating (1.4 A vs. 1.09 A) and 30% lower DC resistance (100 mOhm vs. 143 mOhm), resulting in reduced thermal dissipation and extended component life in current-limited applications.
Regulatory Compliance: The BWVF003030102R2M00 carries explicit ROHS3 compliance certification and REACH unaffected status, meeting stringent environmental requirements for regulated markets.
Extended Temperature Range: The substitute operates from -55°C to 125°C, providing 15°C additional low-temperature margin compared to the primary part.
Tighter Inductance Tolerance: The ±20% tolerance specification provides improved consistency for precision-dependent circuits.

Both parts maintain identical physical footprints, shielding characteristics, ferrite core construction, and surface mount compatibility, enabling direct substitution without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can BWVF003030102R2M00 directly replace SWPA3010S2R2NT on existing PCBs?

A: Yes. Both parts share identical package dimensions (3.00 x 3.00 mm footprint, 1.00 mm nominal height), surface mount technology, and shielded ferrite core construction. No PCB layout modifications are required.

Q: What is the primary electrical difference between these parts?

A: The BWVF003030102R2M00 provides superior electrical performance with 30% lower DC resistance (100 mOhm vs. 143 mOhm) and 28% higher current rating (1.4 A vs. 1.09 A). Both maintain identical 2.2 µH inductance values.

Q: Are there inductance tolerance implications when substituting?

A: The SWPA3010S2R2NT specifies ±30% tolerance while the BWVF003030102R2M00 specifies ±20%. The tighter tolerance of the substitute part provides improved consistency. Both tolerances encompass the nominal 2.2 µH value, maintaining circuit compatibility.

Q: Does the substitute part meet environmental compliance requirements?

A: The BWVF003030102R2M00 carries ROHS3 compliance certification and REACH unaffected status. The SWPA3010S2R2NT compliance status is not specified in available documentation.

Q: What is the temperature operating range difference?
