SK100M063ST Equivalent & Substitute Parts

Part Overview

The SK100M063ST is a 10 µF, 63 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, through-hole configuration. This component is classified as Active and is designed for general-purpose applications requiring stable capacitance performance across a wide operating temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits the use of functionally compatible components from different manufacturers. The substitute parts listed maintain electrical and mechanical compatibility with the SK100M063ST within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the SK100M063ST is determined by strict adherence to the following electrical and mechanical parameters:

Electrical Parameters:

• Capacitance: 10 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 63 V (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Lifetime: 2000 Hrs @ 85°C (exact match required)

Mechanical Parameters:

• Lead Spacing: 0.079" (2.00 mm) (exact match required)
• Size / Dimension: 0.197" Dia (5.00 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• REACH Status: REACH Unaffected (exact match required)

All substitute parts listed meet these criteria. Variations in ESR, ripple current ratings, and height dimensions within the specified maximum seated height do not preclude substitution, as these parameters remain within acceptable operational tolerances for general-purpose applications.

Engineering Selection Recommendations

ECA-1JM100 (Panasonic Electronic Components)

The ECA-1JM100 is classified as Active and represents the preferred substitute for the SK100M063ST. This part maintains full electrical and mechanical compatibility with identical capacitance, voltage rating, tolerance, operating temperature range, and lifetime specifications. The component meets all compliance requirements including ROHS3 and REACH standards. The reduced height dimension (0.472" versus 0.512") provides additional design flexibility for space-constrained applications. Inventory availability of 11,748 units supports consistent supply chain access.

UVR1J100MDD (Nichicon)

The UVR1J100MDD meets all electrical and mechanical substitution criteria and maintains full compliance with ROHS3 and REACH standards. However, this part is classified as Obsolete, indicating discontinued manufacturing status. While functionally equivalent to the SK100M063ST, the Obsolete designation presents long-term supply chain risk. The reduced height dimension (0.433" versus 0.512") is compatible with board-level integration. This part is suitable for substitution only when current inventory is available and long-term supply continuity is not a design requirement. Inventory availability of 23,354 units reflects existing stock levels only.

Frequently Asked Questions (FAQ)

Q: Can the ECA-1JM100 be used as a direct replacement for the SK100M063ST?

A: Yes. The ECA-1JM100 meets all electrical and mechanical specifications required for direct substitution. Both parts share identical capacitance (10 µF), voltage rating (63 V), tolerance (±20%), operating temperature range (-40°C to 85°C), and lifetime rating (2000 Hrs @ 85°C). Lead spacing, case diameter, and mounting type are identical. The reduced height dimension of the ECA-1JM100 (0.472" versus 0.512") is within acceptable tolerance for through-hole radial capacitor applications.

Q: Why is the UVR1J100MDD listed as Obsolete?

A: The Obsolete designation indicates that Nichicon has discontinued manufacturing of the UVR1J100MDD. This classification reflects the product's end-of-life status with the manufacturer. While existing inventory may be available, future procurement cannot be guaranteed. The Obsolete status does not affect the electrical or mechanical compatibility of available units with the SK100M063ST.

Q: Are there differences in ESR between the SK100M063ST and its substitutes?

A: The SK100M063ST specifies an ESR of 11.94 Ohm. The ECA-1JM100 and UVR1J100MDD do not provide ESR specifications in their datasheets. For applications where ESR is a critical design parameter, the SK100M063ST's specified value should be used as the reference. The absence of published ESR data for substitute parts does not preclude their use in general-purpose applications where ESR tolerance is not explicitly defined.

Q: Do the height differences between substitute parts affect PCB layout?

A: The substitute parts have reduced maximum seated heights compared to the SK100M063ST: ECA-1JM100 at 0.472" (12.00 mm) and UVR1J100MDD at 0.433" (11.00 mm) versus the SK100M063ST at 0.512" (13.00 mm). These reductions are compatible with standard through-hole PCB designs. If the original design accommodates the SK100M063ST's height, both substitute parts will fit within the allocated space. No PCB layout modifications are required.

Q: Are all listed parts RoHS and REACH compliant?

A: Yes. The SK100M063ST, ECA-1JM100, and UVR1J100MDD are all ROHS3 Compliant and REACH Unaffected. These compliance certifications ensure compatibility with regulatory requirements for electronic component procurement and use in regulated markets.

Q: What is the difference between Active and Obsolete product status?

A: Active status indicates that the manufacturer continues to produce and support the component. Obsolete status indicates that the manufacturer has discontinued production. The SK100M063ST and ECA-1JM100 are Active products with ongoing manufacturing support. The UVR1J100MDD is Obsolete, meaning no new production is available from Nichicon. For new designs or long-term applications, Active products are preferred to ensure sustained supply chain access.
