Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN101M100ST is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 100 µF (exact match required)
• Voltage rating: 100 V (minimum acceptable)
• Tolerance: ±20% (matching specification)
• Polarization: Bi-Polar (functional requirement)

Mechanical Parameters:

• Package type: Radial, Can (physical form factor)
• Mounting type: Through Hole (PCB interface)
• Lead spacing: 0.295" (7.50 mm) (footprint compatibility)
• Case diameter: 0.630" (16.00 mm) (board clearance)

Compliance Parameters:

• RoHS3 Compliant status (regulatory requirement)
• Operating temperature range: -40°C to 85°C (environmental specification)

The substitute part UVP2A101MHD1TN meets all mandatory electrical, mechanical, and compliance criteria for direct substitution in applications previously using the SN101M100ST.

Parameter Comparison

Engineering Selection Recommendations

The UVP2A101MHD1TN manufactured by Nichicon is a direct electrical and mechanical equivalent to the obsolete SN101M100ST. Both components satisfy identical electrical specifications (100 µF, 100 V, ±20% tolerance) and maintain compatible through-hole radial can package dimensions with matching lead spacing of 0.295" (7.50 mm).

The substitute part demonstrates superior reliability characteristics, with a rated lifetime of 2000 hours at 85°C compared to the original part's 1000-hour specification. The reduced seated height of 1.063" (27.00 mm) versus 1.260" (32.00 mm) provides additional board layout flexibility without compromising electrical performance.

Both components maintain ROHS3 compliance and operate across the identical temperature range of -40°C to 85°C, ensuring regulatory and environmental compatibility in existing applications. The UVP2A101MHD1TN is suitable for direct substitution in general-purpose applications previously utilizing the SN101M100ST.

Frequently Asked Questions (FAQ)

Q: Can the UVP2A101MHD1TN be used as a direct replacement for the SN101M100ST?

A: Yes. Both components share identical electrical specifications (100 µF, 100 V, ±20% tolerance), matching lead spacing (0.295" / 7.50 mm), and compatible through-hole radial can package dimensions. The substitute meets all mandatory substitution criteria.

Q: What is the significance of the height difference between these parts?

A: The UVP2A101MHD1TN has a seated height of 1.063" (27.00 mm) compared to the SN101M100ST's 1.260" (32.00 mm). This 0.197" (5.00 mm) reduction provides additional clearance in space-constrained PCB layouts without affecting electrical performance or footprint compatibility.

Q: Are there compliance differences between the two parts?

A: No. Both the SN101M100ST and UVP2A101MHD1TN are ROHS3 compliant and operate across the identical temperature range of -40°C to 85°C, ensuring equivalent regulatory and environmental compliance.

Q: How do the lifetime ratings compare?

A: The UVP2A101MHD1TN is rated for 2000 hours at 85°C, exceeding the SN101M100ST's 1000-hour specification. This represents improved reliability for extended-life applications.

Q: Are the lead spacings identical?

A: Yes. Both components feature a lead spacing of 0.295" (7.50 mm) and case diameter of 0.630" (16.00 mm), ensuring direct PCB footprint compatibility without layout modifications.

Q: What is the product status of the substitute part?

A: The UVP2A101MHD1TN is classified as "Not For New Designs" by Nichicon. While suitable for replacement and maintenance applications, long-term availability should be evaluated for new product development initiatives.
