Equivalent & Substitute Parts for 108HSM050M

Part Overview

The 108HSM050M is a 1000 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier / Illinois Capacitor. This component is classified as obsolete, with 747 pieces currently in stock. The HSM series capacitor is rated for 2000 hours at 125°C and operates across a temperature range of -40°C to 125°C, suitable for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Due to the obsolete status of the 108HSM050M, identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability. Active alternatives with comparable electrical and mechanical specifications are available from multiple manufacturers including Panasonic, Vishay, Rubycon, EPCOS/TDK, and Chemi-Con.

Frequently Asked Questions (FAQ)

Q1: Can I use a 63 V rated capacitor in place of the 50 V 108HSM050M?

A: Yes. A higher voltage rating provides additional safety margin and does not degrade circuit performance. The 63RX301000M16X31.5 and EGXE630ELL102MLN3S are direct substitutes with 63 V ratings. Voltage rating indicates the maximum voltage the capacitor can safely withstand; using a higher-rated component in a 50 V circuit is electrically compatible.

Q2: What is the significance of AEC-Q200 certification?

A: AEC-Q200 is an automotive-grade qualification standard indicating the component has undergone rigorous testing for reliability, temperature cycling, and long-term performance in automotive environments. Parts with AEC-Q200 certification (B41896C6108M, MAL214691105E3, 50RX301000M16X31.5, 63RX301000M16X31.5, EGXE500ELL102MLN3S, EGXE630ELL102MLN3S) are suitable for automotive and high-reliability applications. Non-certified parts are acceptable for general-purpose applications.

Q3: Why do some substitutes have different heights?

A: Aluminum electrolytic capacitors with identical capacitance and voltage ratings may have different physical dimensions depending on the manufacturer's design and internal construction. The 108HSM050M has a maximum seated height of 33.00 mm. Substitutes with heights up to 33.50 mm are mechanically compatible in most PCB layouts. The MAL214691105E3 at 27.00 mm is shorter and offers space advantage. Verify PCB clearance requirements before selection.

Q4: What does ESR (Equivalent Series Resistance) indicate?

A: ESR represents the internal resistance of the capacitor at a specified frequency. Lower ESR values indicate better high-frequency performance and reduced heat generation. The 108HSM050M specifies 166 mOhm @ 120 Hz. Substitutes with lower impedance values (B41896C6108M at 22 mOhms, B41866C6108M000 at 29 mOhms) provide improved performance. Higher ESR values are acceptable if circuit design permits.

Q5: Is the ±20% tolerance acceptable for my application?

A: The 108HSM050M and all listed substitutes share ±20% tolerance, meaning actual capacitance may vary from 800 µF to 1200 µF. This tolerance is standard for general-purpose aluminum electrolytic capacitors. If tighter tolerance is required, consult the manufacturer for specialized series. For most applications, ±20% tolerance is acceptable.

Q6: What is the difference between 2000-hour and 5000-hour lifetime ratings?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (125°C in this case) before capacitance degradation exceeds acceptable limits. A 5000-hour rating provides 2.5 times longer service life than 2000 hours. For applications requiring extended reliability or operating continuously at elevated temperatures, select parts with higher lifetime ratings (B41896C6108M at 7000 hours, MAL214691105E3 at 5000 hours).

Q7: Can I substitute the 108HSM050M with a surface-mount capacitor?

A: No. The 108HSM050M is a through-hole radial component. All listed substitutes are also through-hole radial packages. Surface-mount capacitors have different mechanical interfaces and are not compatible with through-hole PCB designs. Mounting type must remain unchanged.

Q8: What does "Obsolete" status mean for the 108HSM050M?

A: Obsolete status indicates the manufacturer has discontinued production of this part. While 747 pieces are currently in stock, future availability is not guaranteed. Substitution with active-status parts (all listed alternatives) ensures long-term supply chain continuity and supports future design revisions.

Q9: Are all substitutes ROHS3 compliant?

A: Yes. The 108HSM050M and all listed substitutes are ROHS3 compliant, meeting environmental and hazardous substance restrictions. REACH status is "REACH Unaffected" for all parts, indicating compliance with chemical safety regulations.

Q10: Which substitute offers the best overall performance?

A: Selection depends on application requirements. For general-purpose applications, the EEU-TA1H102 provides direct equivalence. For automotive or high-reliability applications, the B41896C6108M offers the longest lifetime (7000 hours @ 125°C) with AEC-Q200 certification. For space-constrained designs, the MAL214691105E3 provides compact height (27.00 mm) with 5000-hour lifetime and AEC-Q200 certification. Evaluate specific circuit requirements before final selection.
