108HSM010M Equivalent & Substitute Parts Reference

Part Overview

The 108HSM010M is a 1000 µF, 10 V aluminum electrolytic capacitor in radial can package manufactured by Cornell Dubilier/Illinois Capacitor. This component is classified as obsolete, with 710 pieces currently in stock. The HSM series capacitor is designed for general-purpose applications requiring through-hole mounting with a 5.00 mm lead spacing and 10.00 mm diameter form factor.

Due to the obsolete status of the 108HSM010M, equivalent and substitute parts from active manufacturers are necessary for ongoing production support, design refresh cycles, and long-term supply chain continuity. The substitute parts listed maintain the core electrical specifications while offering enhanced performance characteristics, extended operational lifetimes, and active product status from established manufacturers.

Voltage Rating: minimum 10 V (equal or higher acceptable)
Tolerance: ±20% or tighter
Package: Radial, Can configuration
Lead Spacing: 5.00 mm (0.197")
Diameter: 10.00 mm (0.394")
Mounting: Through Hole
Polarization: Polar

Acceptable Variation Parameters:

Height: Maximum 0.866" (22.00 mm) acceptable; original 0.846" (21.50 mm) also acceptable
Operating Temperature: -40°C to 125°C minimum; extended ranges acceptable

Selection Criteria Summary:

All listed substitutes maintain the critical parameters: 1000 µF capacitance, ±20% tolerance, radial can package, 5.00 mm lead spacing, 10.00 mm diameter, and through-hole mounting. Product status is active for all substitutes, ensuring long-term supply availability. Height variations (21.50 mm to 22.00 mm) are within typical PCB design tolerances for through-hole components.

Frequently Asked Questions (FAQ)

Q1: Can I use a 16 V rated capacitor (16RX301000M10X20) in place of the 10 V rated 108HSM010M?

A: Yes. Higher voltage ratings are backward compatible in applications designed for lower voltages. The 16 V capacitor operates safely in a 10 V circuit. This substitution is appropriate when design margins or future specification upgrades are considerations. Verify that the slightly increased height (22.00 mm vs. 21.50 mm) does not create PCB clearance conflicts.

Q2: What is the significance of the ESR (Equivalent Series Resistance) specification?

A: ESR directly affects capacitor performance in ripple current applications and thermal stability. Lower ESR values indicate better high-frequency performance and reduced heat generation. The 108HSM010M specifies 332 mOhm @ 120 Hz. Substitute B41896C3108M000 provides 253 mOhm, representing approximately 24% improvement. For general-purpose applications, ESR differences within this range are not critical; however, for power supply filtering or high-ripple-current circuits, lower ESR substitutes provide enhanced performance.

Q3: Why do some substitute parts have extended lifetime ratings (3000 Hrs or 5000 Hrs vs. 2000 Hrs)?

A: Lifetime ratings reflect the number of hours a capacitor maintains its electrical specifications under specified temperature conditions (typically 125°C). Extended lifetime ratings indicate improved internal construction, higher-quality electrolyte formulations, or more robust separator materials. For applications with continuous operation or high ambient temperatures, extended-lifetime substitutes reduce failure risk and improve system reliability. The 108HSM010M specifies 2000 Hrs @ 125°C; substitutes with 3000 Hrs or 5000 Hrs provide additional operational margin.

Q4: Are all substitute parts RoHS3 compliant?

A: All active substitute parts listed are RoHS3 compliant. The original 108HSM010M (obsolete status) does not specify RoHS compliance. RoHS3 compliance ensures the component meets current environmental and hazardous substance restrictions, which is important for new designs and products destined for regulated markets.

Q5: What is the difference between the Panasonic EEU-TA1A102 and the Chemi-Con EGXE100ELL102MJ20S?

A: Both maintain 10 V rating and 1000 µF capacitance. Key differences: EEU-TA1A102 provides 2000 Hrs @ 125°C lifetime (matching the original), while EGXE100ELL102MJ20S provides 3000 Hrs @ 125°C (50% extended). EGXE100ELL102MJ20S carries AEC-Q200 automotive rating; EEU-TA1A102 does not specify automotive qualification. For general-purpose applications, either is suitable; for automotive or extended-life applications, the Chemi-Con part is preferred.

Q6: Can I substitute the 108HSM010M with a capacitor rated at a lower voltage (e.g., 6.3 V)?

A: No. Voltage rating is a critical parameter that cannot be reduced. A capacitor rated below the circuit operating voltage will fail prematurely or catastrophically. All substitute parts must maintain a minimum 10 V rating. Higher voltage ratings (such as 16 V) are acceptable and provide additional safety margin.

Q7: What does "AEC-Q200" rating mean?

A: AEC-Q200 is an automotive electronics qualification standard that specifies reliability and performance requirements for components used in automotive applications. Components with AEC-Q200 rating have undergone rigorous testing for temperature cycling, vibration, humidity, and other automotive environmental stresses. Several substitute parts (Rubycon RX30 series, EPCOS B41896, Chemi-Con GXL series) carry this certification, making them suitable for automotive or high-reliability applications.

Q8: Does the height difference between 21.50 mm and 22.00 mm affect PCB compatibility?

A: The 0.50 mm height difference is typically within standard PCB design tolerances for through-hole components. However, verify clearance in your specific PCB layout, particularly if the capacitor is located near other tall components, connectors, or enclosure walls. Most modern PCB designs accommodate this variation without modification. If clearance is critical, prioritize substitutes with 21.50 mm height: 108HSM010M (original), 10RX301000M10X20, EGXL100EC3102MJ20S, or EGXL100ELL102MJ20S.

Q9: Which substitute offers the best overall value for general-purpose applications?

A: For general-purpose applications requiring direct replacement, B41896C3108M000 (EPCOS - TDK Electronics) provides optimal value: improved ESR (253 mOhm vs. 332 mOhm), extended lifetime (3500 Hrs vs. 2000 Hrs @ 125°C), extended temperature range (-55°C to 125°C), AEC-Q200 rating, and highest inventory availability (6955 units). This part is suitable for immediate production use without design modification.

Q10: Are there any mechanical compatibility issues when substituting the 108HSM010M?

A: All substitute parts maintain identical lead spacing (5.00 mm) and diameter (10.00 mm), ensuring PCB footprint compatibility. Height variations (21.50 mm to 22.00 mm) are minor and typically accommodated in standard designs. All parts are radial can package with through-hole mounting. No mechanical redesign is required for any listed substitute. Verify final assembly clearance in your specific PCB layout.
