Substitute Part Grouping Explanation

Substitution eligibility for the UPS2C101MHD is determined by the following criteria:

Primary Substitution Parameters:

Capacitance: 100 µF (exact match required)
Voltage Rating: 160 V minimum (equal or higher acceptable)
Tolerance: ±20% (exact match)
Polarization: Polar (exact match)
Mounting Type: Through Hole (exact match)
Package Type: Radial, Can (exact match)
Operating Temperature Range: -40°C ~ 105°C (exact match)

Secondary Considerations:

Lead Spacing: 0.295" (7.50mm) preferred for direct PCB compatibility
Physical Dimensions: Height and diameter variations acceptable if PCB layout permits
Lifetime @ 105°C: Higher values indicate improved reliability
Product Status: Active or Obsolete status noted for supply availability

Substitute parts are grouped into three categories: MFR Recommended (direct replacement with enhanced specifications), Upgrade (higher voltage rating), and Similar (alternative series with compatible electrical parameters).

Engineering Selection Recommendations

MFR Recommended Substitute: UCS2C101MHD6

The UCS2C101MHD6 is the primary recommended replacement. It maintains identical electrical specifications (100 µF, 160 V, ±20% tolerance) while offering a 10000-hour lifetime at 105°C compared to the original 3000 hours. Lead spacing and diameter remain unchanged at 0.295" (7.50mm) and 0.630" (16.00mm), ensuring direct PCB compatibility. Product status is Active, guaranteeing supply availability. Height is reduced to 0.846" (21.50mm), which may provide additional PCB layout flexibility.

Upgrade Option: UCS2E101MHD

For applications requiring higher voltage margin, the UCS2E101MHD provides 250 V rating with the same 100 µF capacitance and 10000-hour lifetime. Lead spacing and diameter match the original part. This upgrade is suitable when circuit design permits higher voltage operation and enhanced reliability is desired.

Alternative Upgrade: 107KFM200M

The 107KFM200M from Cornell Dubilier / Illinois Capacitor offers 200 V rating with 10000-hour lifetime. Physical dimensions and lead spacing match the original UPS2C101MHD exactly, including height of 1.063" (27.00mm). This part is Active and ROHS3 compliant. ESR specification is provided at 2.487 Ohm @ 120 Hz.

Similar Series Options: UCY2C101MHD

The UCY2C101MHD (Nichicon UCY series) provides the highest lifetime rating at 12000 hours with Active product status. However, lead spacing is reduced to 0.197" (5.00mm) and diameter to 0.492" (12.50mm), requiring PCB layout verification before substitution.

Not Recommended for New Designs:

URZ series parts (URZ2C101MHD, URZ2C101MRD6) and UVZ2C101MHD offer only 1000 and 2000-hour lifetimes respectively, providing no improvement over the original part. UVZ2C101MHD is marked "Not For New Designs."

Frequently Asked Questions (FAQ)

Q: Can UCS2C101MHD6 be used as a direct replacement for UPS2C101MHD?

A: Yes. Both parts share identical capacitance (100 µF), voltage rating (160 V), tolerance (±20%), lead spacing (0.295" / 7.50mm), and diameter (0.630" / 16.00mm). The UCS2C101MHD6 has a reduced height of 0.846" (21.50mm) versus 1.063" (27.00mm), which is compatible with most PCB layouts. The UCS2C101MHD6 offers superior reliability with 10000-hour lifetime at 105°C.

Q: What is the difference between the MFR Recommended and Upgrade options?

A: The MFR Recommended substitute (UCS2C101MHD6) maintains the original 160 V rating. The Upgrade option (UCS2E101MHD) increases the voltage rating to 250 V, providing additional safety margin in circuits where voltage transients may occur. Both offer 10000-hour lifetimes and identical lead spacing.

Q: Why does UCY2C101MHD have different lead spacing?

A: The UCY2C101MHD uses 0.197" (5.00mm) lead spacing compared to the original 0.295" (7.50mm). This requires verification that PCB pad spacing accommodates the narrower lead configuration. The part offers superior lifetime (12000 hours) and Active product status.

Q: Can I use 107KFM200M from a different manufacturer?

A: Yes. The 107KFM200M from Cornell Dubilier / Illinois Capacitor meets all electrical and mechanical specifications of the UPS2C101MHD, including identical lead spacing, diameter, and height. It provides 200 V rating and 10000-hour lifetime. Verify that your design accepts components from alternative manufacturers.

Q: What is the impact of height differences on PCB compatibility?

A: Height variations affect vertical clearance on the PCB. The original UPS2C101MHD is 1.063" (27.00mm) tall. Shorter alternatives like UCS2C101MHD6 (0.846" / 21.50mm) provide additional clearance. Taller options like UPJ2C101MHD (1.457" / 37.00mm) require verification of available vertical space. Lead spacing and diameter remain the primary compatibility factors.

Q: Why are some parts marked as Obsolete?

A: Obsolete parts have been discontinued by manufacturers and may have limited inventory. Active status parts ensure long-term supply availability. For new designs or production runs, Active status parts are recommended.

Q: Is RoHS3 compliance maintained across all substitutes?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original UPS2C101MHD specification.
