Substitute Part Grouping Explanation

Substitution for the UPS2A331MHD1TN is determined by strict equivalence in the following parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.295" (7.50 mm) (exact match required)
• Size / Dimension: 0.630" Dia (16.00 mm) (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Variations in lifetime rating, ripple current specifications, and packaging format (Cut Tape vs. Bulk) do not disqualify a part as a substitute, provided all electrical and mechanical parameters remain within specification.

Parameter Comparison

Engineering Selection Recommendations

Both UPW2A331MHD1TN and UPW2A331MHD are direct substitutes for the UPS2A331MHD1TN based on electrical and mechanical parameter equivalence. All three parts are classified as Not For New Designs and carry ROHS3 compliance certification.

The UPW2A331MHD1TN (Cut Tape packaging) and UPW2A331MHD (Bulk packaging) differ only in packaging format and height specification. The UPW series offers extended lifetime (8000 Hrs @ 105°C versus 3000 Hrs @ 105°C), providing improved reliability in applications requiring extended operational life.

Selection between UPW2A331MHD1TN and UPW2A331MHD should be based on procurement requirements: Cut Tape packaging for smaller quantities and automated assembly, or Bulk packaging for larger volume applications.

Frequently Asked Questions (FAQ)

Q: Can UPW2A331MHD1TN replace UPS2A331MHD1TN directly?

A: Yes. Both parts share identical electrical specifications (330 µF, 100 V, ±20% tolerance) and mechanical dimensions (0.630" diameter, 7.50 mm lead spacing, Through Hole mounting). The primary difference is extended lifetime rating in the UPW series.

Q: What is the difference between UPW2A331MHD1TN and UPW2A331MHD?

A: These parts are electrically and mechanically equivalent. The difference is packaging format: UPW2A331MHD1TN is supplied in Cut Tape (CT), while UPW2A331MHD is supplied in Bulk. Additionally, UPW2A331MHD has a maximum seated height of 0.984" (25.00 mm) compared to 1.063" (27.00 mm) for UPW2A331MHD1TN.

Q: Are all three parts ROHS3 compliant?

A: Yes. UPS2A331MHD1TN, UPW2A331MHD1TN, and UPW2A331MHD all carry ROHS3 Compliant certification.

Q: Does the extended lifetime of the UPW series affect compatibility?

A: No. Extended lifetime (8000 Hrs @ 105°C in UPW versus 3000 Hrs @ 105°C in UPS) represents improved performance and does not affect electrical or mechanical compatibility. The UPW series is a direct substitute.

Q: Can I use these capacitors interchangeably in PCB assembly?

A: Yes, provided the PCB layout accommodates the specified lead spacing (0.295" / 7.50 mm) and component height. The UPW2A331MHD has a slightly reduced maximum height (0.984" vs. 1.063"), which may provide additional clearance in space-constrained designs.
