SH101M6R3ST Equivalent & Substitute Parts

Part Overview

The SH101M6R3ST is a 100 µF, 6.3 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, through-hole configuration. This component is classified as obsolete, indicating discontinued production and limited availability. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 2000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Identification of equivalent and substitute parts is necessary due to the obsolete status of the SH101M6R3ST. Equivalent alternatives provide direct functional replacement with identical electrical specifications, while substitute parts offer upgraded performance characteristics or extended component availability from active manufacturers.

Engineering Selection Recommendations

Direct Equivalent (Same Voltage Rating):

SEK101M6R3ST is the primary direct equivalent to SH101M6R3ST. Both components share identical electrical specifications: 100 µF capacitance, 6.3 V rating, ±20% tolerance, and 3.45 Ohm ESR @ 120 Hz. The SEK101M6R3ST is manufactured by Cornell Dubilier Electronics with active product status, ensuring current availability. The operating temperature range extends to -55°C (compared to -40°C on the original), providing enhanced low-temperature performance. Physical dimensions differ slightly in height (0.512" versus 0.433"), which must be verified for space-constrained applications. RoHS3 compliance is maintained.

UPW0J101MDD (Nichicon) provides an alternative direct equivalent at 6.3 V with identical physical height (0.433") and footprint. This part is classified as obsolete but maintains 2000-hour lifetime at 105°C and extended operating temperature range (-55°C ~ 105°C). RoHS3 compliance is confirmed.

Upgraded Alternatives (Higher Voltage Rating):

SEK101M010ST, UHE1A101MDD, UPW1A101MDD, EEU-EB1A101S, and EKZE100ELL101ME11D are 10 V rated alternatives. These parts accept the same 6.3 V operating conditions while providing voltage margin. Selection among these upgraded options depends on availability, lifetime requirements, and physical space constraints:

SEK101M010ST (Cornell Dubilier, Active): 10 V rating, 2.92 Ohm ESR, active status, 0.512" height
UHE1A101MDD (Nichicon, Obsolete): 10 V rating, 4000-hour lifetime, 0.433" height
UPW1A101MDD (Nichicon, Obsolete): 10 V rating, 2000-hour lifetime, 0.433" height
EEU-EB1A101S (Panasonic, Active): 10 V rating, 5000-hour lifetime, 0.472" height
EKZE100ELL101ME11D (Chemi-Con, Active): 10 V rating, 2000-hour lifetime, 0.492" height

All substitute parts maintain ROHS3 compliance and through-hole radial configuration with 0.079" (2.00 mm) lead spacing and 0.197" (5.00 mm) diameter.

Frequently Asked Questions (FAQ)

Q: Can I use a 10 V rated capacitor in place of the 6.3 V SH101M6R3ST?

A: Yes. A 10 V rated capacitor with identical capacitance (100 µF), tolerance (±20%), and physical dimensions operates correctly in circuits designed for 6.3 V. The higher voltage rating provides additional safety margin and does not affect circuit performance when the applied voltage remains at or below 6.3 V.

Q: What is the significance of ESR (Equivalent Series Resistance)?

A: ESR affects ripple current handling and heat generation. Lower ESR values indicate better high-frequency performance. The SH101M6R3ST specifies 3.45 Ohm @ 120 Hz. Substitute parts with equal or lower ESR maintain or improve performance. Parts without specified ESR values require verification from manufacturer datasheets before selection.

Q: Does the height difference between 0.433" and 0.512" affect compatibility?

A: Physical height differences must be evaluated against available board space and component clearance requirements. The SEK101M6R3ST (0.512" height) is taller than the original SH101M6R3ST (0.433" height). Verify clearance in your specific application before substitution. Lead spacing (0.079") and diameter (0.197") remain constant across all alternatives.

Q: Why are some substitute parts listed as obsolete?

A: Obsolete parts indicate discontinued production. While currently available in inventory, long-term sourcing cannot be guaranteed. Active status parts (SEK101M6R3ST, EEU-EB1A101S, EKZE100ELL101ME11D) are preferred for new designs and long-term production requirements.

Q: What does RoHS3 compliance mean?

A: RoHS3 (Restriction of Hazardous Substances Directive 3) compliance certifies that the component meets European environmental standards by restricting specified hazardous materials. All listed substitute parts maintain RoHS3 compliance, ensuring regulatory compatibility.

Q: How do I select between multiple 10 V alternatives?

A: Selection criteria include: (1) Product Status—active parts ensure availability; (2) Lifetime @ 105°C—longer lifetimes (5000 hours for EEU-EB1A101S) provide extended service life; (3) Physical Height—verify clearance in your application; (4) Manufacturer—consider supply chain reliability and technical support availability.

Q: Is the operating temperature range important for my application?

A: Yes. The SH101M6R3ST operates from -40°C to 105°C. Most substitutes extend the lower limit to -55°C, providing enhanced cold-temperature performance. Verify that your application requirements fall within the selected part's operating range.

Q: Can I interchange parts with different ripple current ratings?

A: Ripple current capacity must meet or exceed your circuit requirements. Higher ripple current ratings indicate better performance under AC stress conditions. Verify that selected substitute parts support your circuit's ripple current demands at both 120 Hz and 10 kHz operating frequencies.
