SK332M010ST Equivalent & Substitute Parts

Part Overview

The SK332M010ST is a 3300 µF, 10 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, through-hole configuration. This capacitor is rated for general-purpose applications with a 2000-hour lifetime at 85°C and operates across a temperature range of -40°C to 85°C. The part is currently Active in product status and fully compliant with RoHS3 and REACH regulations.

Substitute parts become necessary when the primary manufacturer's stock is unavailable, when design requirements permit alternative qualified sources, or when legacy components require replacement with current production alternatives. The SK332M010ST has been identified with one direct substitute that maintains electrical and mechanical compatibility within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SK332M010ST is determined by strict equivalence across the following parameters:

Electrical Parameters (Must Match):

• Capacitance: 3300 µF
• Voltage Rating: 10 V
• Tolerance: ±20%
• Operating Temperature Range: -40°C to 85°C
• Lifetime at Temperature: 2000 Hrs @ 85°C

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package Type: Radial, Can
• Lead Spacing: 0.197" (5.00mm)
• Polarization: Polar

Regulatory Parameters (Must Match):

• RoHS3 Compliance
• REACH Status: REACH Unaffected

The substitute part UVR1A332MHD meets all critical electrical, mechanical, and regulatory requirements. Physical dimensions (can diameter and height) are within acceptable manufacturing tolerances for through-hole PCB mounting. Ripple current ratings at both low and high frequencies remain within acceptable operational parameters for general-purpose applications.

Engineering Selection Recommendations

Primary Part: SK332M010ST (CDE)

The SK332M010ST is the recommended selection for new designs. This part carries Active product status, indicating ongoing manufacturer support, availability, and continued production. Full compliance with RoHS3 and REACH regulations is confirmed. The part is currently in stock with 1038 units available.

Substitute Part: UVR1A332MHD (Nichicon)

The UVR1A332MHD is a qualified substitute for applications where the primary part is unavailable. This part meets all critical electrical and mechanical specifications with equivalent capacitance, voltage rating, tolerance, operating temperature range, and lifetime rating. Physical dimensions are compatible with through-hole PCB layouts designed for the SK332M010ST. Ripple current performance is within acceptable parameters for general-purpose applications.

The UVR1A332MHD carries a "Not For New Designs" product status, indicating that Nichicon has discontinued active development of this series. This designation does not affect compatibility with existing designs but indicates that long-term availability may be limited. The part is currently in stock with 2544 units available.

Selection Criteria:

For new product development, select the SK332M010ST to ensure long-term supply chain stability and manufacturer support. For legacy system repairs or replacement of failed components in existing installations, the UVR1A332MHD provides electrical and mechanical equivalence. Both parts satisfy regulatory compliance requirements for RoHS3 and REACH.

Frequently Asked Questions (FAQ)

Q: Can the UVR1A332MHD be used as a direct replacement for the SK332M010ST on existing PCBs?

A: Yes. Both parts are through-hole radial capacitors with identical lead spacing (0.197" / 5.00mm), identical capacitance (3300 µF), voltage rating (10 V), and operating temperature range (-40°C to 85°C). Physical dimensions are compatible; the UVR1A332MHD has a slightly smaller can diameter (0.492" vs. 0.512") and height (0.866" vs. 0.906"), which does not affect PCB mounting or electrical performance.

Q: What does "Not For New Designs" mean for the UVR1A332MHD?

A: This product status indicates that Nichicon has discontinued active development and marketing of the UVR series. The part remains available from existing inventory but is not recommended for incorporation into new product designs. Existing designs using this part may continue to operate without modification.

Q: Are there differences in ESR (Equivalent Series Resistance) between these parts?

A: The SK332M010ST specifies ESR at 100 mOhm @ 120 Hz. The UVR1A332MHD does not provide ESR specification in the available data. For applications where ESR is a critical design parameter, the SK332M010ST is the preferred selection.

Q: Do both parts have the same ripple current rating?

A: Both parts support ripple current operation at low and high frequencies. The SK332M010ST is rated for 1.4 A @ 120 Hz and 1.54 A @ 1 kHz. The UVR1A332MHD is rated for 1.45 A @ 120 Hz and 1.6675 A @ 10 kHz. These ratings are compatible for general-purpose applications.

Q: Are both parts RoHS3 and REACH compliant?

A: Yes. Both the SK332M010ST and UVR1A332MHD are RoHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: The SK332M010ST has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The UVR1A332MHD lists MSL as Not Applicable, which is consistent with through-hole aluminum electrolytic capacitor construction.

Q: Can these parts be used interchangeably in high-ripple-current applications?

A: Both parts are rated for general-purpose applications with specified ripple current limits. The UVR1A332MHD provides slightly higher ripple current capability at high frequency (1.6675 A @ 10 kHz vs. 1.54 A @ 1 kHz for the SK332M010ST). For applications requiring maximum ripple current performance, verify that the selected part's rating meets the circuit requirement.
