SN100M010ST Equivalent & Substitute Parts Reference

Part Overview

The SN100M010ST is a 10 µF, 10 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete and operates across a temperature range of -40°C to 85°C with a 1000-hour lifetime rating at 85°C. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for ongoing design support and production continuity. Substitute parts maintain the same capacitance and tolerance specifications while offering improved lifetime ratings and active product status from alternative manufacturers.

Substitute Part Grouping Explanation

Substitution of the SN100M010ST is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Capacitance: 10 µF (exact match required)
Tolerance: ±20% (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)
Lead Spacing: 0.079" (2.00mm) (exact match required)
Diameter: 0.197" (5.00mm) (exact match required)
Operating Temperature Range: -40°C to 85°C (minimum requirement)
RoHS Status: ROHS3 Compliant (exact match required)

Voltage Rating Substitution Logic: The SN100M010ST operates at 10 V rated voltage. Substitute parts with higher voltage ratings (16 V, 25 V, 35 V) are electrically compatible in circuits designed for 10 V operation. Higher voltage ratings provide increased safety margin and are direct substitutes for the original 10 V specification.

Lifetime Enhancement: Substitute parts from Panasonic and Nichicon offer 2000-hour lifetime ratings at 85°C, compared to the original 1000-hour rating, representing a 2x improvement in operational longevity.

Engineering Selection Recommendations

Primary Recommendation - Panasonic ECE-A1 Series (Active Status):

The Panasonic ECE-A1CN100U, ECE-A1EN100U, and ECE-A1VN100U parts are recommended as primary substitutes for the SN100M010ST. All three Panasonic alternatives maintain active product status, ensuring long-term availability and supply chain continuity. These parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The 2000-hour lifetime rating at 85°C provides extended operational reliability compared to the original 1000-hour specification.

Voltage Selection Guidance:

ECE-A1CN100U (16 V): Direct upgrade for applications with 10 V nominal operation and moderate voltage headroom requirements.
ECE-A1EN100U (25 V): Suitable for applications requiring additional voltage margin and enhanced transient protection.
ECE-A1VN100U (35 V): Appropriate for applications with significant voltage transients or where maximum safety margin is required.

All three voltage ratings are electrically compatible with the original 10 V specification and provide identical capacitance, tolerance, and mechanical form factors.

Secondary Recommendation - Nichicon UVP Series (Obsolete Status):

The Nichicon UVP1C100MDD, UVP1E100MDD, and UVP1V100MDD parts are secondary alternatives. While these parts offer 2000-hour lifetime ratings and maintain the original 0.433" (11.00mm) height dimension, they carry obsolete product status. These parts are suitable for applications where existing inventory must be maintained or where the reduced height is a critical design constraint.

Height Consideration:

Panasonic ECE-A1 series parts have a maximum seated height of 0.472" (12.00mm), compared to 0.433" (11.00mm) for the original SN100M010ST and Nichicon UVP series. PCB layout verification is required if height clearance is constrained.

Frequently Asked Questions (FAQ)

Q: Can I use a 16 V, 25 V, or 35 V rated capacitor in place of the 10 V SN100M010ST?

A: Yes. Higher voltage-rated capacitors are direct electrical substitutes for lower voltage applications. A 16 V, 25 V, or 35 V rated capacitor will function correctly in a circuit designed for 10 V operation. The higher voltage rating provides increased safety margin and transient protection.

Q: What is the difference between the Panasonic and Nichicon substitute options?

A: Both manufacturers provide equivalent electrical performance with 2000-hour lifetime ratings. The primary differences are: (1) Panasonic ECE-A1 series parts have active product status, ensuring long-term availability; (2) Nichicon UVP series parts are obsolete but maintain the original 11.00mm height; (3) Panasonic parts are 12.00mm tall, requiring PCB layout verification for height-constrained applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (Panasonic ECE-A1CN100U, ECE-A1EN100U, ECE-A1VN100U, and Nichicon UVP1C100MDD, UVP1E100MDD, UVP1V100MDD) are ROHS3 compliant and suitable for applications requiring regulatory compliance.

Q: What is the lead spacing requirement, and do all substitutes match?

A: The SN100M010ST requires 0.079" (2.00mm) lead spacing. All listed Panasonic and Nichicon substitutes maintain this identical lead spacing, ensuring direct PCB compatibility without layout modifications.

Q: Does the increased lifetime rating (2000 hours vs. 1000 hours) affect circuit design?

A: No. The increased lifetime rating represents improved component reliability and longevity. Circuit design parameters remain unchanged. The substitute parts are electrically and mechanically equivalent to the original specification.

Q: Which substitute should I select if PCB height is constrained?

A: If PCB clearance is limited to 11.00mm or less, select Nichicon UVP1C100MDD, UVP1E100MDD, or UVP1V100MDD, which maintain the original 0.433" (11.00mm) height. Panasonic ECE-A1 series parts are 0.472" (12.00mm) tall and require additional clearance.

Q: Are there any ripple current differences between substitutes?

A: Ripple current ratings vary slightly across substitutes. The SN100M010ST is rated at 42 mA @ 120 Hz. Panasonic ECE-A1CN100U is rated at 40 mA @ 120 Hz; ECE-A1EN100U at 45 mA @ 120 Hz; ECE-A1VN100U at 43 mA @ 120 Hz. Nichicon UVP series parts are rated at 42-43 mA @ 120 Hz. All values are within acceptable operating parameters for general-purpose applications.

Q: Can I mix different voltage ratings in the same circuit?

A: Yes. Different voltage-rated substitutes can be used in the same circuit if the application design permits. All substitutes maintain identical capacitance (10 µF), tolerance (±20%), and mechanical form factors. Voltage rating selection should be based on individual circuit requirements and transient protection needs.
