Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria applied strictly to the provided parameters:

Primary Matching Criteria:

• Inductance value must be 2.2 µH (exact match required)
• Mounting type must be Surface Mount (identical PCB assembly process)
• Package footprint must be 5.00 x 5.00 mm (identical land pattern)
• Operating temperature range must encompass or match the application requirement
• Current rating must equal or exceed 3.8 A
• Saturation current must equal or exceed 5.5 A

Secondary Compatibility Criteria:

• DC resistance should not exceed 25 mOhm to maintain thermal performance
• Shielding type (shielded or semi-shielded) acceptable for EMI-sensitive applications
• Inductance tolerance of ±20% or ±30% acceptable for general circuit applications
• Moisture sensitivity level MSL 1 (unlimited) required for standard assembly processes

Identified Substitutes:

1. BWVS005050402R2M00 (Pulse Electronics) — Fully qualified substitute with improved DC resistance (21 mOhm) and extended low-temperature rating (-55°C)

2. SDCH1V5040-2R2M-R (Eaton - Electronics Division) — Qualified substitute with semi-shielded construction and higher current rating (4.2 A)

Parameter Comparison

Engineering Selection Recommendations

BWVS005050402R2M00 (Pulse Electronics)

This substitute is suitable for applications where the SWPA5040S2R2NT is unavailable. The part meets all primary electrical specifications with identical inductance and package footprint. The lower DC resistance (21 mOhm versus 25 mOhm maximum) provides improved thermal efficiency. The extended operating temperature range (-55°C to 125°C) accommodates wider environmental conditions. Both ROHS3 compliance and REACH unaffected status confirm regulatory alignment. The saturation current of 5.7 A exceeds the main part specification. Height difference of 0.20 mm (4.20 mm versus 4.00 mm) must be evaluated against PCB clearance constraints.

SDCH1V5040-2R2M-R (Eaton - Electronics Division)

This substitute is suitable for applications requiring higher current capacity. The part delivers 4.2 A continuous current rating, exceeding the main part by 0.4 A. Identical inductance, package footprint, and DC resistance specifications ensure direct functional compatibility. Semi-shielded construction differs from the main part's fully shielded design; this substitution is appropriate for applications where full shielding is not required. ROHS3 compliance and REACH unaffected status confirm regulatory alignment. Height of 4.10 mm falls between the main part and the Pulse Electronics alternative. The saturation current of 4.9 A is lower than the main part specification and must be evaluated against peak current requirements.

Both substitutes are active products with confirmed inventory availability and identical mounting technology. Selection between substitutes depends on specific application requirements regarding current capacity, shielding level, and thermal performance.

Frequently Asked Questions (FAQ)

Q: Can BWVS005050402R2M00 be used as a direct replacement for SWPA5040S2R2NT?

A: Yes, BWVS005050402R2M00 is a direct substitute. Both parts share identical inductance (2.2 µH), package footprint (5.00 x 5.00 mm), and surface mount technology. The substitute offers improved DC resistance (21 mOhm versus 25 mOhm maximum) and extended low-temperature rating (-55°C versus -40°C). Height difference of 0.20 mm must be verified against PCB clearance requirements.

Q: Can SDCH1V5040-2R2M-R be used as a direct replacement for SWPA5040S2R2NT?

A: Yes, SDCH1V5040-2R2M-R is a qualified substitute for applications where semi-shielded construction is acceptable. Both parts share identical inductance (2.2 µH), package footprint (5.00 x 5.00 mm), DC resistance (25 mOhm maximum), and surface mount technology. The substitute provides higher continuous current rating (4.2 A versus 3.8 A). Shielding type difference must be evaluated against electromagnetic interference requirements.

Q: What is the primary difference between the two substitutes?

A: BWVS005050402R2M00 maintains fully shielded construction with lower DC resistance and extended temperature range. SDCH1V5040-2R2M-R offers semi-shielded construction with higher current capacity. Selection depends on whether full shielding is required and whether the higher current rating is beneficial for the application.

Q: Are all three parts compatible with the same PCB footprint?

A: All three parts use identical 5.00 x 5.00 mm package footprints and surface mount technology. Height differences (4.00 mm, 4.20 mm, and 4.10 mm respectively) must be evaluated against PCB clearance constraints and component stacking requirements.

Q: Do the substitutes meet regulatory compliance requirements?

A: BWVS005050402R2M00 and SDCH1V5040-2R2M-R are both ROHS3 compliant and REACH unaffected. The main part SWPA5040S2R2NT does not specify these certifications. Regulatory compliance must be confirmed for the specific application and end-use market.

Q: What is the significance of the inductance tolerance difference?

A: The main part specifies ±30% tolerance while both substitutes specify ±20% tolerance. Tighter tolerance in substitutes provides more precise inductance values. For applications sensitive to inductance variation, the ±20% tolerance substitutes offer improved performance consistency.

Q: Can saturation current differences affect circuit performance?

A: Yes. The main part saturates at 5.5 A, BWVS005050402R2M00 at 5.7 A, and SDCH1V5040-2R2M-R at 4.9 A. If circuit peak currents approach or exceed 4.9 A, SDCH1V5040-2R2M-R saturation characteristics must be evaluated. BWVS005050402R2M00 provides the highest saturation margin.

Q: What does MSL 1 (Unlimited) moisture sensitivity level mean?

A: MSL 1 indicates the component requires no special moisture protection during storage, handling, or assembly. All three parts share this classification, confirming compatibility with standard manufacturing processes without baking or desiccant requirements.
