Substitute parts are grouped into three categories based on their relationship to the main part:

Direct Substitutes maintain identical electrical specifications and physical dimensions, differing only in series designation or lifetime rating. These include UAQ2D101MHD6, UVY2D101MHD, and UAS2D101MHD6.

Upgraded Substitutes provide enhanced performance characteristics such as higher voltage ratings or extended lifetime ratings while maintaining the same capacitance and physical footprint. These include UCY2V101MHD (350 V, 12000 Hrs) and UPW2D101MHD (8000 Hrs lifetime).

Manufacturer-Recommended Substitutes include UVZ2E101MHD, which operates at 250 V rated voltage, providing additional voltage margin for the same capacitance value.

Similar Substitutes maintain core electrical specifications but may differ in physical dimensions (case diameter, height, or lead spacing). These include UAQ2D101MHD, UAS2D101MHD, and UCS2D101MND9.

Engineering Selection Recommendations

For Direct Replacement (Identical Footprint and Electrical Performance)

UAQ2D101MHD6 and UAS2D101MHD6 are the primary direct substitutes for the UPS2D101MHD. Both maintain the 0.630" (16.00mm) case diameter and 0.295" (7.50mm) lead spacing. UAQ2D101MHD6 is active and recommended for new designs. UAS2D101MHD6 is also active and provides higher ripple current capability (430 mA @ 120 Hz versus 335 mA), making it suitable for applications with elevated ripple current requirements.

For Extended Lifetime Applications

UPW2D101MHD provides 8000 hours lifetime at 105°C compared to the original 3000 hours, though it is classified as obsolete. UCY2V101MHD offers the longest lifetime at 12000 hours with an upgraded 350 V rating, active product status, and significantly higher ripple current handling (825 mA @ 120 Hz). This part is suitable for applications requiring enhanced reliability and voltage margin.

For Voltage Margin Enhancement

UVZ2E101MHD provides a 250 V rated voltage while maintaining 100 µF capacitance and the same physical footprint. This part is manufacturer-recommended and suitable for applications where additional voltage safety margin is required, though it carries "Not For New Designs" status.

For Space-Constrained Applications

UCS2D101MND9 offers the most compact case diameter (0.394" / 10.00mm) with extended 10000-hour lifetime and active product status. This part requires verification of lead spacing compatibility (0.197" / 5.00mm versus 0.295" / 7.50mm) with the PCB layout.

All recommended substitutes maintain ROHS3 compliance and the -40°C to 105°C operating temperature range of the original part.

Frequently Asked Questions (FAQ)

Q: Can UAQ2D101MHD6 be used as a direct replacement for UPS2D101MHD?

A: Yes. UAQ2D101MHD6 maintains identical capacitance (100 µF), voltage rating (200 V), tolerance (±20%), case diameter (0.630" / 16.00mm), and lead spacing (0.295" / 7.50mm). The primary difference is reduced lifetime (2000 hours versus 3000 hours at 105°C), which is acceptable for most general-purpose applications. UAQ2D101MHD6 is active and recommended for new designs.

Q: What is the difference between UAQ2D101MHD6 and UAS2D101MHD6?

A: Both parts share identical electrical ratings and physical dimensions. UAS2D101MHD6 provides higher ripple current capability (430 mA @ 120 Hz and 688 mA @ 10 kHz versus 335 mA @ 120 Hz and 536 mA @ 10 kHz). Select UAS2D101MHD6 for applications with elevated ripple current requirements.

Q: Why would I select UCY2V101MHD over a direct substitute?

A: UCY2V101MHD provides four times the lifetime (12000 hours versus 3000 hours at 105°C) and a higher voltage rating (350 V versus 200 V). This part is active and suitable for long-life applications or designs requiring additional voltage safety margin. The higher ripple current rating (825 mA @ 120 Hz) also supports more demanding electrical environments.

Q: Are there physical dimension constraints I should consider?

A: Yes. Most direct substitutes maintain the 0.630" (16.00mm) case diameter and 0.295" (7.50mm) lead spacing. However, height varies: UPS2D101MHD is 1.319" (34.60mm), while UAQ2D101MHD6 and UAS2D101MHD6 are 1.063" (27.00mm) and 0.866" (22.00mm) respectively. Verify PCB layout clearance before selection. UCS2D101MND9 uses 0.197" (5.00mm) lead spacing, requiring PCB layout verification.

Q: Is RoHS compliance maintained across all substitutes?

A: Yes. All substitute parts listed maintain ROHS3 compliance, matching the original UPS2D101MHD specification.

Q: What is the significance of "Active" versus "Obsolete" product status?

A: Active parts are in current production and recommended for new designs. Obsolete parts are no longer manufactured. For new designs, select active substitutes such as UAQ2D101MHD6, UAS2D101MHD6, UCY2V101MHD, or UCS2D101MND9. For legacy system maintenance, obsolete parts may still be available from inventory.

Q: Can I use UCS2D101MND9 as a substitute if my PCB layout uses 0.295" (7.50mm) lead spacing?

A: No. UCS2D101MND9 uses 0.197" (5.00mm) lead spacing and a smaller case diameter (0.394" / 10.00mm). PCB layout modification is required. This part is suitable only for new designs where lead spacing can be accommodated.
