Parameter Comparison

Engineering Selection Recommendations

BWVC006060452R2M00 (Pulse Electronics)

This substitute provides improved inductance tolerance (±20% versus ±30%), slightly higher current rating (4.68 A versus 4.6 A), and enhanced saturation current (8.55 A versus 7.4 A). The DC resistance remains at 18mOhm, matching the original specification. Extended operating temperature range (-55°C to 125°C) provides additional thermal margin. ROHS3 compliance and REACH unaffected status confirm regulatory alignment. Height increase to 4.70mm requires verification of PCB clearance constraints.

BWVS006060452R2M00 (Pulse Electronics)

This substitute offers the highest current rating (5.1 A) and saturation current (8.8 A) among all alternatives, with tighter inductance tolerance (±20%). DC resistance of 18.4mOhm remains within acceptable limits. Extended operating temperature range (-55°C to 125°C) and full regulatory compliance (ROHS3, REACH unaffected) support deployment in demanding applications. Height of 4.70mm and nonstandard package require mechanical verification.

SDCH1V6045-2R2M-R (Eaton - Electronics Division)

This substitute maintains the original height specification (4.50mm) and operating temperature range (-40°C to 125°C), simplifying mechanical integration. Inductance tolerance improves to ±20%. However, current rating (4.5 A) is marginally lower than the original, and DC resistance increases to 22mOhm maximum. Semi-shielded construction differs from the fully shielded original, affecting electromagnetic interference characteristics. ROHS3 compliance and REACH unaffected status confirm regulatory requirements.

All substitute parts are active products with confirmed inventory availability and maintain the same 6.00mm x 6.00mm footprint and ferrite core material as the original component.

Frequently Asked Questions (FAQ)

Q: Can BWVC006060452R2M00 be used as a direct replacement for SWPA6045S2R2NT?

A: BWVC006060452R2M00 meets all critical electrical specifications: 2.2 µH inductance, 4.68 A current rating, 18mOhm DC resistance, and ferrite shielded construction. The 6.00mm x 6.00mm footprint is identical. The seated height increases from 4.50mm to 4.70mm, requiring verification of available PCB clearance. Inductance tolerance improves from ±30% to ±20%.

Q: What is the difference between shielded and semi-shielded inductors?

A: Shielded inductors (BWVC006060452R2M00, BWVS006060452R2M00, SWPA6045S2R2NT) provide complete electromagnetic shielding, reducing radiated emissions and susceptibility to external magnetic fields. Semi-shielded inductors (SDCH1V6045-2R2M-R) offer partial shielding, resulting in lower cost and reduced height but increased electromagnetic coupling to surrounding components. Selection depends on EMI/EMC requirements of the application.

Q: Why does BWVS006060452R2M00 have higher current rating than the original part?

A: BWVS006060452R2M00 achieves 5.1 A continuous current rating through optimized core geometry and winding design while maintaining the same 2.2 µH inductance and 6.00mm x 6.00mm footprint. Higher saturation current (8.8 A) indicates improved magnetic material utilization. This provides additional design margin for applications requiring higher current capacity.

Q: Are all substitute parts RoHS and REACH compliant?

A: BWVC006060452R2M00, BWVS006060452R2M00, and SDCH1V6045-2R2M-R are all ROHS3 compliant and REACH unaffected. The original SWPA6045S2R2NT does not specify RoHS or REACH status in the provided data. Regulatory compliance documentation should be verified with manufacturers for specific applications.

Q: What is the impact of DC resistance variation on circuit performance?

A: DC resistance directly affects power dissipation and voltage drop across the inductor. SWPA6045S2R2NT specifies 18mOhm maximum. BWVC006060452R2M00 matches this at 18mOhm. BWVS006060452R2M00 increases to 18.4mOhm (0.4mOhm increase). SDCH1V6045-2R2M-R increases to 22mOhm maximum (4mOhm increase). At 4.6 A, the 22mOhm resistance produces 0.1 W dissipation, requiring thermal evaluation in power-sensitive applications.

Q: Can SDCH1V6045-2R2M-R be used in applications requiring full electromagnetic shielding?

A: SDCH1V6045-2R2M-R is semi-shielded, not fully shielded. Applications requiring complete electromagnetic isolation or operating in high-EMI environments should use fully shielded alternatives: BWVC006060452R2M00 or BWVS006060452R2M00. Semi-shielded construction is suitable for applications with moderate EMI requirements and cost constraints.

Q: What is the significance of inductance tolerance in circuit design?

A: Inductance tolerance affects filter response, resonant frequency, and impedance matching. SWPA6045S2R2NT specifies ±30% tolerance, while all substitutes offer ±20% tolerance. Tighter tolerance reduces circuit performance variation and simplifies design margin calculations. Applications with critical frequency response or impedance requirements benefit from the improved tolerance of substitute parts.

Q: Are the substitute parts available in the same packaging format?

A: SWPA6045S2R2NT is supplied in Tape & Reel (TR). BWVC006060452R2M00 is supplied in Tape & Reel (TR). BWVS006060452R2M00 is supplied in Cut Tape (CT) & Digi-Reel®. SDCH1V6045-2R2M-R is supplied in Tape & Reel (TR). Packaging format affects handling, storage, and automated assembly compatibility. Verify packaging requirements with manufacturing and assembly operations.
