Substitute Part Grouping Explanation

Substitute parts for the UPW2C101MHH are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes maintain identical electrical specifications (100 µF, 160 V, ±20% tolerance) and mechanical dimensions (0.630" diameter, 0.984" height, 0.295" lead spacing). These parts are interchangeable in applications where the original specifications are required.

Upgrade Substitutes provide enhanced electrical performance while maintaining mechanical compatibility. These parts increase voltage rating or lifetime specifications, allowing operation in more demanding environments without physical redesign.

The substitution logic is based strictly on:

Capacitance value (100 µF)
Voltage rating (160 V minimum for direct substitutes; 250 V for upgrades)
Tolerance (±20%)
Physical dimensions and lead spacing (identical for all substitutes)
Mounting type (Through Hole, Radial configuration)
Polarization (Polar)

Engineering Selection Recommendations

UPW2C101MHD is a direct substitute for the UPW2C101MHH, maintaining identical electrical and mechanical specifications. This part is classified as obsolete but achieves ROHS3 compliance, making it suitable for applications requiring regulatory adherence. Inventory availability is significantly higher (4611 pcs) compared to the original part (702 pcs).

EKXG251ELL101ML25S is an upgrade substitute manufactured by Chemi-Con. This part maintains mechanical compatibility while providing enhanced electrical performance: 250 V voltage rating (versus 160 V), 10000-hour lifetime at 105°C (versus 8000 hours), and doubled ripple current capacity at 120 Hz (680 mA versus 330 mA). The part carries active product status and ROHS3 compliance. Selection of this upgrade is appropriate for applications where higher voltage margin or extended operational lifetime is beneficial.

Frequently Asked Questions (FAQ)

Q: Can UPW2C101MHD be used as a direct replacement for UPW2C101MHH?

A: Yes. Both parts share identical capacitance (100 µF), voltage rating (160 V), tolerance (±20%), physical dimensions (0.630" diameter, 0.984" height, 0.295" lead spacing), and mounting configuration (Through Hole, Radial). The primary difference is packaging format and RoHS compliance status.

Q: What are the advantages of selecting EKXG251ELL101ML25S over the direct substitutes?

A: EKXG251ELL101ML25S provides three performance enhancements: increased voltage rating (250 V versus 160 V), extended lifetime (10000 hours versus 8000 hours at 105°C), and higher ripple current capacity (680 mA at 120 Hz versus 330 mA). These improvements allow operation in higher-stress electrical environments without circuit redesign. The part maintains identical physical dimensions and mounting configuration.

Q: Are all substitute parts mechanically compatible with the original PCB layout?

A: Yes. All substitute parts maintain identical lead spacing (0.295" / 7.50 mm), case diameter (0.630" / 16.00 mm), and seated height (0.984" / 25.00 mm). No PCB modifications are required for substitution.

Q: What is the difference between the packaging formats listed for UPW2C101MHH and UPW2C101MHD?

A: UPW2C101MHH is supplied in standard packaging, while UPW2C101MHD is supplied in bulk packaging. Both parts are identical in electrical and mechanical specifications; packaging format affects only order quantity and handling procedures.

Q: Which substitute part should be selected for new designs?

A: Selection depends on application requirements. For direct replacement in existing designs, UPW2C101MHD provides equivalent performance with improved compliance status. For new designs or applications requiring enhanced performance margins, EKXG251ELL101ML25S is recommended due to its active product status, higher voltage rating, and extended lifetime specification.
