Substitute Part Grouping Explanation

Substitute parts for the SEK101M010ST are identified based on strict electrical and mechanical parameter matching. The primary criteria for substitution are:

Electrical Parameters:

• Capacitance: 100 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lifetime: 2000 Hrs @ 105°C (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)

Mechanical Parameters:

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

Compliance Parameters:

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

Two substitute parts meet these criteria: UPW1A101MDD (Nichicon) and ELXZ100ELL101MEB5D (Chemi-Con). Both parts satisfy all mandatory electrical, mechanical, and compliance requirements for direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

SEK101M010ST (Cornell Dubilier Electronics) - Primary Component

The SEK101M010ST maintains Active product status with full availability and ROHS3 compliance. This part is suitable for general-purpose applications and serves as the baseline reference for substitution analysis.

UPW1A101MDD (Nichicon) - Direct Electrical Equivalent

The UPW1A101MDD is electrically and mechanically equivalent to the SEK101M010ST, matching all critical parameters including capacitance, voltage rating, tolerance, lifetime, and operating temperature range. However, this part carries Obsolete product status, indicating discontinued manufacturing. The UPW1A101MDD has a reduced seated height of 0.433" (11.00mm) compared to the SEK101M010ST at 0.512" (13.00mm), which may provide space advantages in height-constrained PCB layouts. Selection of this part should account for its obsolete status and potential supply limitations.

ELXZ100ELL101MEB5D (Chemi-Con) - Direct Electrical Equivalent with Automotive Qualification

The ELXZ100ELL101MEB5D is electrically and mechanically equivalent to the SEK101M010ST across all critical parameters. This part maintains Active product status with ROHS3 compliance and REACH Unaffected designation. The ELXZ100ELL101MEB5D carries AEC-Q200 automotive qualification rating, indicating suitability for automotive-grade applications. The seated height matches the SEK101M010ST at 0.512" (13.00mm). Selection of this part is appropriate for applications requiring automotive-grade components or when general-purpose specifications are insufficient.

Frequently Asked Questions (FAQ)

Q1: Can UPW1A101MDD be used as a direct replacement for SEK101M010ST?

A: The UPW1A101MDD meets all electrical and mechanical substitution criteria, including capacitance, voltage rating, tolerance, lifetime, operating temperature range, lead spacing, and package type. However, the UPW1A101MDD carries Obsolete product status. The reduced seated height of 0.433" (11.00mm) versus 0.512" (13.00mm) for the SEK101M010ST may affect PCB layout compatibility. Verify component availability before design implementation.

Q2: What is the difference between ELXZ100ELL101MEB5D and SEK101M010ST?

A: Both parts are electrically and mechanically equivalent with matching capacitance (100 µF), voltage rating (10 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), and operating temperature range (-55°C ~ 105°C). The ELXZ100ELL101MEB5D includes AEC-Q200 automotive qualification, making it suitable for automotive applications. The SEK101M010ST is designated for general-purpose applications. Both maintain Active product status and ROHS3 compliance.

Q3: Are there height differences between substitute parts?

A: Yes. The SEK101M010ST and ELXZ100ELL101MEB5D both have a maximum seated height of 0.512" (13.00mm). The UPW1A101MDD has a reduced seated height of 0.433" (11.00mm). This difference may impact PCB layout and component placement. Verify clearance requirements in your specific application before substitution.

Q4: Which substitute part should be selected for new designs?

A: For new designs requiring general-purpose specifications, the ELXZ100ELL101MEB5D (Chemi-Con) is recommended due to its Active product status, ROHS3 compliance, and availability. If automotive-grade qualification is required, the ELXZ100ELL101MEB5D is the appropriate selection. The UPW1A101MDD should be avoided in new designs due to its Obsolete status.

Q5: Do all substitute parts meet RoHS and REACH compliance?

A: Yes. Both UPW1A101MDD and ELXZ100ELL101MEB5D are ROHS3 compliant and REACH Unaffected, matching the compliance status of the SEK101M010ST.

Q6: What are the ripple current specifications for substitute parts?

A: The SEK101M010ST specifies 110 mA @ 120 Hz and 132 mA @ 10 kHz. The UPW1A101MDD specifies 117 mA @ 120 Hz and 180 mA @ 100 kHz. The ELXZ100ELL101MEB5D specifies 70 mA @ 120 Hz and 175 mA @ 100 kHz. Verify ripple current requirements for your specific application circuit.
