Engineering Selection Recommendations

Primary Substitute: SDED20161T-3R3MS

The SDED20161T-3R3MS is the direct equivalent from Delta Electronics/Cyntec, the original manufacturer. This part maintains identical electrical specifications including 3.3 µH inductance, ±20% tolerance, 1.05 A current rating, and 292 mOhm maximum DC resistance. The SDED20161T-3R3MS is in Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating. This substitute provides the highest level of compatibility and is the preferred choice for direct replacement.

Secondary Substitutes: Pulse Electronics BWVC Series

The BWVC002016103R3M00 and BWVC002016103R3T00 are functionally equivalent alternatives from Pulse Electronics. Both maintain the 3.3 µH inductance, 0806 package, and shielded construction. The BWVC002016103R3M00 offers ±20% tolerance matching the original specification, while the BWVC002016103R3T00 provides ±30% tolerance. Both parts are rated for 880 mA continuous current with 295 mOhm DC resistance. These parts are suitable for applications where the lower current rating is acceptable within circuit design margins.

Tertiary Substitutes: Pulse Electronics BWVH Series

The BWVH002016103R3MH1 and BWVH002016103R3TH1 provide alternative specifications with 800 mA current rating and 380 mOhm DC resistance. The BWVH002016103R3MH1 maintains ±20% tolerance, while BWVH002016103R3TH1 offers ±30% tolerance. These parts are suitable for applications with lower current requirements and where increased DC resistance is acceptable.

All substitute parts are ROHS3 compliant, operate across the -55°C to 125°C temperature range, and maintain the 0806 (2016 Metric) surface mount package specification.

Frequently Asked Questions (FAQ)

Q: Can the SDED20161T-3R3MS directly replace the PSD20161T-3R3MS?

A: Yes. The SDED20161T-3R3MS is manufactured by the same company (Delta Electronics/Cyntec) and maintains identical electrical and mechanical specifications. It is the direct equivalent and primary substitute.

Q: What is the difference between the BWVC and BWVH series substitutes?

A: The BWVC series is rated for 880 mA continuous current with 295 mOhm DC resistance. The BWVH series is rated for 800 mA continuous current with 380 mOhm DC resistance. Both maintain the 3.3 µH inductance and 0806 package. Selection depends on circuit current requirements and acceptable DC resistance values.

Q: Are there differences in tolerance between substitute parts?

A: Yes. Parts designated with "M" in the part number (BWVC002016103R3M00, BWVH002016103R3MH1) offer ±20% inductance tolerance. Parts designated with "T" (BWVC002016103R3T00, BWVH002016103R3TH1) offer ±30% inductance tolerance. The original PSD20161T-3R3MS specifies ±20% tolerance.

Q: Do all substitute parts fit the same PCB footprint?

A: All substitute parts use the 0806 (2016 Metric) package with identical length and width dimensions (0.079" L x 0.063" W). The BWVH series has a maximum seated height of 0.040" (1.02mm) compared to 0.039" (1.00mm) for other parts. This minimal difference does not affect PCB footprint compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and carry unlimited moisture sensitivity rating (MSL 1).

Q: Which substitute should I select if my circuit requires the full 1.05 A current rating?

A: The SDED20161T-3R3MS is the only substitute that maintains the 1.05 A current rating specification. If lower current ratings are acceptable within your circuit design, the BWVC series (880 mA) or BWVH series (800 mA) may be used.

Q: What is the significance of the "Not For New Designs" status on the original part?

A: This designation indicates the PSD20161T-3R3MS has been discontinued for new product development by the manufacturer. The SDED20161T-3R3MS from the same manufacturer is the recommended replacement for ongoing production and new designs.
