SN010M063ST Equivalent & Substitute Parts

Part Overview

The Cornell Dubilier Electronics (CDE) SN010M063ST is a 1 µF, 63 V aluminum electrolytic capacitor in radial, can package format. This component is classified as Obsolete product status. Locating alternative equivalent or substitute parts becomes necessary due to discontinued manufacturing and limited remaining inventory. Suitable replacement candidates must maintain functional compatibility while meeting or exceeding the original electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN010M063ST is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance: 1 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 63 V or higher (rated voltage must equal or exceed original specification)
• Operating Temperature Range: -40°C ~ 85°C (must cover the same range)
• Lead Spacing: 0.079" (2.00mm) (exact match required for PCB compatibility)
• Size / Dimension: 0.197" Dia (5.00mm) (exact match required for mounting clearance)
• Package / Case: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)

The substitute parts identified meet these core criteria while offering improvements in lifetime rating and active product status, making them suitable direct replacements in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

Würth Elektronik 860010772005 (WCAP-ATG8 Series)

This part is designated Active product status with doubled lifetime rating (2000 Hrs @ 85°C versus 1000 Hrs @ 85°C for the original). The 63 V voltage rating provides exact electrical compatibility. ROHS3 compliance and EAR99 classification maintain regulatory alignment. The increased height (12.50mm vs. 11.00mm) requires PCB clearance verification but does not affect electrical performance. This represents the closest functional equivalent with superior longevity characteristics.

Nichicon UVP2A010MDD (UVP Series)

This part carries Obsolete product status matching the original part's current classification. The 100 V voltage rating provides increased margin above the original 63 V specification, suitable for applications requiring voltage headroom. Lifetime rating equals the Würth option at 2000 Hrs @ 85°C. The increased height (12.50mm vs. 11.00mm) requires identical PCB clearance consideration. ROHS3 compliance and EAR99 classification preserve regulatory requirements. Selection between this option and the Würth part depends on availability priorities and voltage margin requirements.

Frequently Asked Questions (FAQ)

Q: Can the UVP2A010MDD (100 V rating) directly replace the SN010M063ST (63 V rating)?

A: Yes. The 100 V rated part is electrically compatible in any circuit designed for 63 V operation. The higher voltage rating provides additional safety margin and does not compromise circuit function. However, verify that circuit layout permits the increased package height (12.50mm vs. 11.00mm).

Q: Are there physical mounting differences between the substitute parts and the original?

A: All three parts maintain identical lead spacing (0.079" / 2.00mm) and base diameter (0.197" / 5.00mm). The original part has maximum seated height of 0.433" (11.00mm), while both substitutes reach 0.492" (12.50mm). Confirm available clearance above the capacitor on the PCB before component selection.

Q: What is the significance of the lifetime rating difference (1000 Hrs vs. 2000 Hrs @ 85°C)?

A: Lifetime rating indicates expected operational duration under specified temperature conditions. The original SN010M063ST specifies 1000 Hrs @ 85°C. Both substitute parts provide doubled lifetime (2000 Hrs @ 85°C), resulting in extended service life in equivalent thermal environments. This improvement does not affect immediate compatibility but enhances reliability in long-duration applications.

Q: Why does one substitute part show Bi-Polar while others show Polar polarization?

A: Polarization classification describes internal capacitor construction. Bi-Polar construction permits operation in either polarity direction. Polar construction requires correct polarity orientation during installation. The original SN010M063ST is Bi-Polar. The Würth Elektronik 860010772005 is Polar, requiring observance of polarity markings during assembly. The Nichicon UVP2A010MDD maintains Bi-Polar construction, matching the original design. Circuit design determines whether bi-polar capability is functionally required.

Q: Are all three parts ROHS3 compliant?

A: Yes. The original SN010M063ST and both substitute parts (Würth Elektronik 860010772005 and Nichicon UVP2A010MDD) are certified ROHS3 compliant, ensuring environmental and regulatory compatibility across all three options.

Q: Which substitute part is recommended for new designs?

A: The Würth Elektronik 860010772005 carries Active product status, indicating current manufacturing and ongoing supplier availability. This status is preferred for designs requiring long-term component sourcing and supply chain stability. The Nichicon UVP2A010MDD, while functionally equivalent, carries Obsolete status like the original part, indicating limited future availability.
