SS100M035ST Equivalent & Substitute Parts Reference

Part Overview

The SS100M035ST is a 10 µF, 35 V aluminum electrolytic capacitor in radial configuration manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, with 871 pieces currently in stock. The part features a 1000-hour lifetime rating at 85°C and an equivalent series resistance (ESR) of 15.92 Ohm at 120 Hz, making it suitable for general-purpose applications requiring stable capacitance in through-hole mounting configurations.

Due to its obsolete status, identifying equivalent and substitute parts is necessary for ongoing design support, maintenance, and production continuity. Substitute components must maintain compatibility across critical electrical parameters including capacitance value, voltage rating, tolerance, and physical dimensions to ensure direct replacement capability.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

ECE-A1VKA100 (Panasonic Electronic Components) and ECE-A1VKS100 (Panasonic Electronic Components) are parametric equivalents to the SS100M035ST, maintaining 10 µF capacitance, 35 V rating, ±20% tolerance, and identical physical dimensions (0.197" diameter, 0.079" lead spacing). Both parts are ROHS3 compliant and active products with substantial inventory availability (11,045 and 16,068 units respectively). ECE-A1VKA100 features a maximum seated height of 7.00 mm, matching the original specification exactly.

For Enhanced Reliability (Extended Lifetime):

SK100M035ST (Cornell Dubilier Electronics) and ESK106M035AC3AA (KEMET) provide 2000-hour lifetime ratings at 85°C, doubling the endurance specification of the original part while maintaining all primary electrical parameters. Both are active products with high inventory levels (6,230 and 21,737 units). Note that SK100M035ST has a maximum seated height of 13.00 mm and ESK106M035AC3AA measures 12.50 mm, requiring verification of available PCB clearance.

For Voltage Margin Enhancement:

ECE-A1HKA100 (Panasonic Electronic Components) provides a 50 V rating with identical 10 µF capacitance and ±20% tolerance, suitable for applications requiring additional voltage safety margin. This part is ROHS3 compliant, active, and available in high quantity (30,734 units). Physical dimensions match the original specification (0.197" diameter, 0.079" lead spacing, 7.00 mm height).

For Extended Temperature Operation:

EEA-GA1V100 (Panasonic Electronic Components) maintains 10 µF, 35 V specifications with extended operating temperature range (-55°C to 105°C) and 1000-hour lifetime at 105°C. This part is ROHS3 compliant, active, and suitable for applications requiring enhanced thermal performance. Physical dimensions are identical to the original part.

All recommended substitutes are ROHS3 compliant and suitable for general-purpose applications. Selection should be based on specific application requirements regarding lifetime, voltage margin, temperature range, and available PCB space.

Frequently Asked Questions (FAQ)

Q: Can SK100M035ST be used as a direct replacement for SS100M035ST?

A: SK100M035ST maintains identical electrical specifications (10 µF, 35 V, ±20% tolerance, 15.92 Ohm ESR) and physical diameter (5.00 mm) with matching lead spacing (2.00 mm). However, the seated height is 13.00 mm compared to the original 7.00 mm. Verification of available PCB clearance is required before substitution.

Q: What is the difference between ECE-A1VKS100 and ECE-A1VKA100?

A: Both parts are Panasonic products with identical electrical specifications (10 µF, 35 V, ±20% tolerance). ECE-A1VKS100 belongs to the KS series with 6.00 mm maximum seated height, while ECE-A1VKA100 belongs to the KA series with 7.00 mm maximum seated height. The KA series part matches the original SS100M035ST height specification exactly.

Q: Is ECE-A1HKA100 compatible with the original circuit design?

A: ECE-A1HKA100 maintains identical capacitance (10 µF), tolerance (±20%), physical diameter (5.00 mm), lead spacing (2.00 mm), and height (7.00 mm). The voltage rating is 50 V instead of 35 V, which is acceptable for direct substitution as higher voltage ratings do not affect circuit operation in applications designed for 35 V. This part provides additional voltage safety margin.

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

A: ESR specifications are not provided for all substitute parts in the available data. Where ESR is specified (SK100M035ST at 15.92 Ohm), it matches the original part. ESR values depend on frequency and temperature conditions. For applications where ESR is critical, parts with documented ESR specifications should be prioritized.

Q: Can EEA-GA1V100 be used in high-temperature applications?

A: EEA-GA1V100 is rated for 1000 hours at 105°C with an operating temperature range of -55°C to 105°C, compared to the original part's -40°C to 85°C range. This part is suitable for applications requiring extended temperature performance. All other electrical parameters (10 µF, 35 V, ±20% tolerance) remain identical.

Q: What is the inventory status for substitute parts?

A: ECE-A1VKS100 has the highest inventory (16,068 units), followed by ECE-A1HKA100 (30,734 units) and ESK106M035AC3AA (21,737 units). SK100M035ST offers 6,230 units. All substitute parts are currently in stock as new original components.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant, matching the environmental compliance status of the original SS100M035ST. This ensures compatibility with modern manufacturing and regulatory requirements.

Q: What is the difference between "Active" and "Obsolete" product status?

A: Active products are currently manufactured and supported by the supplier, ensuring ongoing availability and technical support. Obsolete products are no longer manufactured. The SS100M035ST is obsolete; therefore, active substitute parts (ECE-A1VKS100, ECE-A1HKA100, EEA-GA1V100, ESK106M035AC3AA, ECE-A1VKA100) are recommended for new designs and long-term production continuity.
