SEK102M010ST Equivalent & Substitute Parts Reference

Part Overview

The SEK102M010ST is a 1000 µF, 10 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in radial, can package configuration. This component is classified as Active product status and is designed for general-purpose applications requiring through-hole mounting. The part operates across a temperature range of -55°C to 105°C with a rated lifetime of 2000 hours at 105°C.

Substitute parts become necessary when the primary manufacturer part is unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits equivalent electrical and mechanical specifications. The substitute parts listed maintain identical or compatible electrical ratings and physical dimensions to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SEK102M010ST is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Capacitance: 1000 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Tolerance: ±20% (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match required)
• Lifetime: 2000 Hrs @ 105°C (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Diameter: 0.394" (10.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

Allowable Variation Parameters:

• Height - Seated (Max): Variation permitted within PCB assembly constraints
• ESR (Equivalent Series Resistance): Variation permitted if electrical performance requirements are met
• Ripple Current ratings: Variation permitted based on application requirements

All substitute parts listed meet the critical matching parameters and are therefore electrically and mechanically interchangeable with the SEK102M010ST in standard through-hole PCB applications.

Engineering Selection Recommendations

Primary Selection (Active Status): The ECA-1AHG102 from Panasonic Electronic Components is the preferred substitute for new designs. This part maintains Active product status, ensuring long-term availability and manufacturer support. It meets all critical electrical and mechanical parameters and carries ROHS3 compliance certification. The lower seated height of 0.531" (13.50mm) compared to the SEK102M010ST provides additional PCB assembly flexibility.

Secondary Selection (Legacy Applications): The UPS1A102MPD from Nichicon is classified as "Not For New Designs" and should be selected only when supporting existing production runs or legacy equipment where design changes are not feasible. This part meets all critical substitution parameters and maintains ROHS3 compliance. The higher seated height of 0.689" (17.50mm) requires verification against PCB layout constraints.

Compliance Verification: All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can the UPS1A102MPD be used in new product designs? A: The UPS1A102MPD carries a "Not For New Designs" product status designation. While it meets all electrical and mechanical substitution criteria, Panasonic ECA-1AHG102 is the recommended choice for new designs due to its Active status and assured long-term availability.

Q: What is the significance of the height variation between substitute parts? A: The SEK102M010ST has a maximum seated height of 0.630" (16.00mm), the UPS1A102MPD measures 0.689" (17.50mm), and the ECA-1AHG102 measures 0.531" (13.50mm). Height differences must be verified against PCB layout and component clearance requirements. The ECA-1AHG102 offers the most compact profile, while the UPS1A102MPD requires additional vertical clearance.

Q: Are all substitute parts through-hole mounted? A: Yes. All listed substitute parts are through-hole mounted components with identical lead spacing of 0.197" (5.00mm) and matching radial, can package configuration. Surface-mount alternatives are not included in this reference.

Q: Do the substitute parts maintain the same electrical performance? A: All substitute parts match the critical electrical specifications: 1000 µF capacitance, 10 V voltage rating, ±20% tolerance, 2000 hours lifetime at 105°C, and -55°C to 105°C operating temperature range. ESR values vary (SEK102M010ST: 290 mOhm, UPS1A102MPD: 140 mOhms), which may affect ripple current handling in high-frequency applications.

Q: Are all parts RoHS compliant? A: Yes. The SEK102M010ST, UPS1A102MPD, and ECA-1AHG102 are all ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic component manufacturing.

Q: What is the inventory status of these parts? A: The SEK102M010ST has 791 pieces in stock, the UPS1A102MPD has 2748 pieces in stock, and the ECA-1AHG102 has 11240 pieces in stock. Inventory levels should be verified at time of procurement.
