SH101M035ST Equivalent & Substitute Parts Reference

Part Overview

The SH101M035ST is a 100 µF, 35 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). 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.

Due to obsolete status and limited inventory (889 pieces), identification of active equivalent and substitute parts is necessary to ensure design continuity and long-term supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the SH101M035ST is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria (Must Match):

Capacitance: 100 µF
Tolerance: ±20%
Voltage Rating: 35 V or higher
Mounting Type: Through Hole
Package Type: Radial, Can
Lead Spacing: 0.138" (3.50 mm)
Diameter: 0.315" (8.00 mm)
Height: 0.453" (11.50 mm) or compatible

Secondary Compatibility Factors:

Operating Temperature Range: -40°C to 105°C minimum
Lifetime @ 105°C: 2000 hours minimum
RoHS3 Compliance required

Substitute parts are grouped into two categories:

Category A - Direct Equivalents (35 V Rating): Parts maintaining the original 35 V voltage specification with identical or superior electrical characteristics.

Category B - Upgraded Substitutes (50 V Rating): Parts with elevated voltage rating (50 V) providing enhanced voltage margin while maintaining all mechanical and thermal specifications. These are suitable for applications where the original 35 V specification permits higher-rated components.

Engineering Selection Recommendations

For Direct Replacement (35 V Specification):

SEK101M035ST (CDE) is the primary recommended substitute. This part maintains identical electrical specifications (100 µF, 35 V, ±20%, 1.86 Ohm ESR, 2000 Hrs @ 105°C) while offering active product status and significantly higher inventory availability (48,257 pieces). The extended operating temperature range (-55°C to 105°C) provides additional thermal margin compared to the original SH101M035ST (-40°C to 105°C). Both parts are ROHS3 compliant and share identical mechanical dimensions and lead spacing.

EEU-FC1V101 (Panasonic) provides an alternative direct equivalent with active status. This part maintains the 35 V specification and 2000-hour lifetime. The lower impedance (117 mOhms) indicates superior high-frequency performance characteristics. AEC-Q200 automotive rating provides additional quality assurance. However, inventory is limited (778 pieces).

For Upgraded Voltage Specification (50 V):

EEU-EB1H101S (Panasonic) is recommended for applications permitting higher voltage rating. This part offers enhanced reliability with 5000-hour lifetime at 105°C (2.5× improvement over original specification) while maintaining identical mechanical form factor and ROHS3 compliance. Active product status and substantial inventory (25,914 pieces) ensure long-term availability.

UPW1H101MPD (Nichicon) provides an alternative 50 V upgrade with 3000-hour lifetime and active design consideration. The extended temperature range (-55°C to 105°C) and improved ripple current handling (315.25 mA @ 120 Hz) support demanding applications. Inventory availability is adequate (17,612 pieces).

Parts Not Recommended for New Designs:

UHE1H101MPD, UPS1H101MPD, and UPW1V101MPD carry "Not For New Designs" status and should be avoided for new product development despite adequate inventory levels.

Frequently Asked Questions (FAQ)

Q1: Can SEK101M035ST directly replace SH101M035ST without circuit modification?

A: Yes. SEK101M035ST maintains identical electrical specifications (100 µF, 35 V, ±20% tolerance, 1.86 Ohm ESR, 2000 Hrs @ 105°C) and mechanical dimensions (lead spacing 0.138", diameter 0.315", height 0.453"). The extended temperature range (-55°C to 105°C) provides additional margin. No circuit modification is required.

Q2: What is the difference between 35 V and 50 V rated substitutes?

A: The 50 V rated parts (EEU-EB1H101S, UHE1H101MPD, UPS1H101MPD, UPW1H101MPD) provide higher voltage margin and typically extended lifetime ratings. These are suitable for applications where the circuit design permits higher-rated components. The 35 V specification of the original part must be verified as a minimum requirement before selecting 50 V alternatives.

Q3: Why does EEU-FC1V101 show lower impedance (117 mOhms) compared to SH101M035ST (1.86 Ohm)?

A: Impedance and ESR are measured at different frequencies and conditions. EEU-FC1V101 impedance is specified at 100 kHz, while SH101M035ST ESR is specified at 120 Hz. Lower impedance at high frequency indicates superior performance in ripple current applications. Both parts meet the 2000-hour lifetime specification at 105°C.

Q4: Is RoHS3 compliance maintained across all substitute parts?

A: Yes. All recommended substitute parts (SEK101M035ST, EEU-FC1V101, EEU-EB1H101S, UHE1H101MPD, UPS1H101MPD, UPW1H101MPD, UPW1V101MPD) are ROHS3 compliant, matching the original SH101M035ST specification.

Q5: What does "Not For New Designs" status mean?

A: This designation indicates the manufacturer has discontinued active support for new product development. While these parts remain available in inventory, they are not recommended for designs entering production. SEK101M035ST and EEU-FC1V101 (35 V) or EEU-EB1H101S (50 V) are preferred for new designs.

Q6: Can mechanical dimensions vary between substitute parts?

A: All recommended substitutes maintain identical lead spacing (0.138" / 3.50 mm), diameter (0.315" / 8.00 mm), and height specifications (0.453" / 11.50 mm for 35 V parts; 0.492" / 12.50 mm for EEU-EB1H101S). Verify PCB layout compatibility before final selection.

Q7: Which substitute offers the longest operational lifetime?

A: EEU-EB1H101S provides 5000 hours at 105°C, representing 2.5× improvement over the original 2000-hour specification. UHE1H101MPD offers 7000 hours but carries "Not For New Designs" status.
