SH332M010ST Equivalent & Substitute Parts Reference

Part Overview

The SH332M010ST is a 3300 µF, 10 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, with 742 pieces currently in stock. The part operates across a temperature range of -40°C to 105°C and is designed for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Substitution becomes necessary due to the obsolete product status of the SH332M010ST. Active equivalent parts from alternative manufacturers provide continued availability, improved reliability specifications, and compliance with current supply chain requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Critical Matching Parameters:

Capacitance: 3300 µF (exact match required)
Voltage Rating: 10 V (exact match required)
Tolerance: ±20% (exact match required)
Lead Spacing: 5.00 mm (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

Compatible Variation Parameters:

Operating Temperature Range: Substitute parts may extend the lower temperature limit (e.g., -55°C vs. -40°C) without affecting compatibility
Lifetime @ Temperature: Substitute parts may offer equal or extended lifetime specifications
ESR and Impedance: Substitute parts may offer equal or lower values, improving performance
Ripple Current Ratings: Substitute parts may offer equal or higher ratings

All substitute parts listed maintain identical electrical ratings (3300 µF, 10 V, ±20%) and mechanical dimensions (5.00 mm lead spacing, radial can package, through-hole mounting). Variations in lifetime specifications, ESR characteristics, and ripple current capabilities represent performance enhancements or equivalent performance levels.

Engineering Selection Recommendations

Primary Recommendation for Active Designs:

SEK332M010ST (Cornell Dubilier Electronics) is the direct upgrade path from the obsolete SH332M010ST. Both parts are manufactured by the same supplier, maintaining design continuity. The SEK series extends the operating temperature range to -55°C to 105°C while preserving all other electrical and mechanical specifications. Product status is Active, ensuring long-term availability and supply chain stability.

Alternative Active Substitutes (Ranked by Compliance and Availability):

EEU-FR1A332 (Panasonic Electronic Components) — Active product status with 10,000-hour lifetime specification at 105°C. Maintains all critical electrical parameters and mechanical dimensions. REACH Unaffected status provides regulatory clarity.
10ZLH3300MEFC12.5X20 (Rubycon) — Active product status with extended 10,000-hour lifetime. Slightly reduced physical dimensions (12.50 mm diameter vs. 13.00 mm) require PCB layout verification. REACH Unaffected status.
EEU-EB1A332 (Panasonic Electronic Components) — Active product status with 10,000-hour lifetime and extended height (27.00 mm). Suitable for applications with vertical clearance availability. REACH Unaffected status.

Not Recommended for New Designs:

UHE1A332MHD (Nichicon) and UPW1A332MHD (Nichicon) carry "Not For New Designs" status. While electrically compatible, these parts should be reserved for legacy system maintenance only. UHE1A332MHD carries REACH Affected status, requiring additional compliance documentation.

Dimensional Considerations:

The original SH332M010ST features a 13.00 mm diameter can. Most active substitutes use 12.50 mm diameter cans, reducing overall footprint. Height variations range from 21.50 mm to 27.00 mm. Verify PCB layout clearance before final selection, particularly for applications with space constraints or adjacent component placement.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different physical diameter?

A: The original SH332M010ST uses a 13.00 mm diameter can. Most active substitutes employ 12.50 mm diameter cans. This reduction in diameter is compatible with standard through-hole PCB layouts designed for 5.00 mm lead spacing. However, verify that the reduced diameter does not interfere with adjacent components or mechanical mounting structures. Height variations must also be confirmed against available vertical clearance.

Q: What is the difference between "Active" and "Not For New Designs" product status?

A: Active products are currently manufactured and supported by the supplier, with guaranteed long-term availability and supply chain continuity. "Not For New Designs" products are in production but not recommended for new circuit designs; these parts should be used only for legacy system repairs or maintenance. For new applications, select only Active-status parts.

Q: Does the extended operating temperature range of SEK332M010ST (-55°C to 105°C vs. -40°C to 105°C) affect circuit performance?

A: No. The extended lower temperature limit of the SEK332M010ST represents an enhancement, not a change in electrical behavior. The part maintains identical capacitance, voltage rating, tolerance, and ESR specifications across the entire operating range. The wider temperature range provides additional design margin for applications exposed to extreme cold environments.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this reference carry ROHS3 Compliant status, matching the original SH332M010ST. This ensures compatibility with current manufacturing standards and regulatory requirements across global markets.

Q: What does "REACH Unaffected" or "REACH Affected" mean for component selection?

A: REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) is a European Union regulation governing chemical substances in products. "REACH Unaffected" indicates the part contains no restricted substances requiring special documentation. "REACH Affected" parts may contain substances requiring additional compliance verification. For applications subject to EU regulations, prioritize REACH Unaffected parts to simplify compliance documentation.

Q: Can I substitute based on lifetime specifications alone?

A: No. Lifetime specifications (measured in hours at 105°C) indicate reliability and expected service life but do not determine electrical or mechanical compatibility. All substitute parts must match the critical parameters: capacitance (3300 µF), voltage rating (10 V), tolerance (±20%), lead spacing (5.00 mm), package type (radial can), and mounting type (through-hole). Lifetime is a secondary selection criterion used to differentiate between otherwise equivalent parts.

Q: Why do some substitute parts have different ESR or impedance values?

A: ESR (Equivalent Series Resistance) and impedance values reflect internal construction differences between manufacturers. Lower ESR or impedance values indicate improved performance characteristics, particularly for high-frequency ripple current applications. The original SH332M010ST specifies 100 mOhm ESR at 120 Hz. Substitute parts with equal or lower impedance values (e.g., 17-35 mOhms) provide equivalent or superior performance without affecting basic circuit function.

Q: Is the SEK332M010ST the only recommended substitute?

A: SEK332M010ST is the primary recommendation due to manufacturer continuity and Active product status. However, EEU-FR1A332, 10ZLH3300MEFC12.5X20, and EEU-EB1A332 are equally valid alternatives from established manufacturers with Active status and extended lifetime specifications. Selection depends on availability, lead time, and specific application requirements (temperature range, physical space constraints, ripple current demands).
