SN101M063ST Equivalent & Substitute Parts

Part Overview

The SN101M063ST is a 100 µF, 63 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing maintenance and repair applications. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 1000 hours at 85°C and is suitable for general-purpose applications requiring through-hole mounting.

Substitute Part Grouping Explanation

Substitution of the SN101M063ST is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Capacitance value: 100 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Bi-Polar (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)
• Lead spacing: 0.295" (7.50 mm) (exact match required)
• Case diameter: 0.630" (16.00 mm) (exact match required)
• Operating temperature range: -40°C ~ 85°C (minimum requirement)
• RoHS compliance: ROHS3 Compliant (exact match required)

Allowable Variation Parameters:

• Voltage rating: Substitute must equal or exceed 63 V
• Lifetime @ 85°C: Substitute must equal or exceed 1000 Hrs
• Ripple current @ 120 Hz: Substitute must equal or exceed 410 mA
• Height - Seated (Max): Substitute may exceed 0.984" within PCB layout constraints
• ESR: Substitute specifications may differ if not explicitly constrained by application

The UVP2A101MHD1TN meets all critical matching parameters and exceeds allowable variation thresholds.

Parameter Comparison

Engineering Selection Recommendations

The UVP2A101MHD1TN from Nichicon is a direct functional substitute for the SN101M063ST. Both components share identical electrical specifications for capacitance, tolerance, and operating temperature range. The substitute part exceeds the original specification in voltage rating (100 V vs. 63 V), lifetime at 85°C (2000 Hrs vs. 1000 Hrs), and ripple current capacity (425 mA vs. 410 mA).

The primary physical difference is the seated height: the UVP2A101MHD1TN measures 1.063" (27.00 mm) compared to the original 0.984" (25.00 mm), representing a 0.079" (2.00 mm) increase. This height differential must be evaluated against PCB layout constraints and available vertical clearance in the target application.

Both parts maintain ROHS3 compliance and bi-polar polarization. The substitute carries "Not For New Designs" status, consistent with the obsolete status of the original part. Selection of the UVP2A101MHD1TN is appropriate for replacement and repair applications where the increased height does not conflict with mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can the UVP2A101MHD1TN directly replace the SN101M063ST without circuit modification?

A: The UVP2A101MHD1TN is electrically compatible with the SN101M063ST. Both components have identical capacitance (100 µF), tolerance (±20%), and operating temperature range (-40°C ~ 85°C). The substitute's higher voltage rating (100 V) and extended lifetime (2000 Hrs @ 85°C) do not require circuit changes. Physical compatibility depends on PCB layout; the substitute is 0.079" (2.00 mm) taller and must fit within available vertical clearance.

Q: What is the significance of the voltage rating difference?

A: The SN101M063ST is rated for 63 V, while the UVP2A101MHD1TN is rated for 100 V. In replacement applications, the higher voltage rating of the substitute provides additional safety margin and does not degrade performance in circuits designed for 63 V operation. The substitute will function correctly in any circuit where the original 63 V part was specified.

Q: Does the height difference affect PCB compatibility?

A: The UVP2A101MHD1TN is 0.079" (2.00 mm) taller than the SN101M063ST (1.063" vs. 0.984" seated height). This difference must be evaluated against available vertical clearance on the PCB and any mechanical constraints such as enclosure height, component stacking, or proximity to other tall components. If vertical space is limited, physical verification is required before installation.

Q: Are both parts RoHS compliant?

A: Both the SN101M063ST and UVP2A101MHD1TN are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the difference between the product statuses "Obsolete" and "Not For New Designs"?

A: The SN101M063ST is classified as obsolete, indicating it is no longer manufactured or supported by Cornell Dubilier Electronics. The UVP2A101MHD1TN carries "Not For New Designs" status from Nichicon, indicating it remains available for existing applications but is not recommended for new product development. Both statuses reflect legacy component classifications; the substitute remains suitable for replacement and repair of existing equipment.

Q: Are there any ESR considerations for substitution?

A: The SN101M063ST specifies ESR of 1.59 Ohm @ 120Hz. The UVP2A101MHD1TN does not provide an explicit ESR specification in the available data. For applications where ESR is a critical parameter (such as high-frequency ripple filtering or low-impedance power supply circuits), ESR performance should be verified through the manufacturer's detailed technical documentation or direct testing before final selection.
