338HSM016M Equivalent & Substitute Parts

Part Overview

The 338HSM016M is a 3300 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier / Illinois Capacitor. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The part operates across a temperature range of -40°C to 125°C with a rated lifetime of 2000 hours at 125°C, serving general-purpose applications requiring stable capacitance and low equivalent series resistance.

Substitute Part Grouping Explanation

Substitution of the 338HSM016M is determined by the following critical parameters:

Primary Matching Criteria:

Capacitance: 3300 µF (exact match required)
Voltage Rating: 16 V (minimum acceptable)
Tolerance: ±20% (standard for aluminum electrolytic capacitors)
Package: Radial, Can (physical and electrical compatibility)
Mounting: Through Hole (PCB assembly compatibility)
Lead Spacing: 0.295" (7.50 mm) (footprint compatibility)
Case Diameter: 0.630" (16.00 mm) (board layout compatibility)

Secondary Compatibility Parameters:

Operating Temperature Range: -40°C to 125°C minimum
Polarization: Polar (required for electrolytic capacitors)
Height: Maximum 1.319" (33.50 mm) acceptable for most applications

Substitute parts are grouped into two categories: direct equivalents (matching 16 V rating) and upgrades (higher voltage ratings or extended lifetime specifications). All substitute parts maintain identical capacitance, tolerance, package geometry, and lead spacing to ensure direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can I use a 25 V rated capacitor in place of the 16 V 338HSM016M?

A: Yes, provided the circuit design permits. A 25 V capacitor is electrically compatible with a 16 V circuit application. The higher voltage rating provides additional safety margin. However, verify that the increased height (1.319" versus 1.299") does not create clearance issues on the PCB.

Q: What is the difference between direct equivalents and upgraded substitutes?

A: Direct equivalents maintain the original 16 V rating and 2000-hour lifetime specification. Upgraded substitutes offer extended lifetime (4000 to 7000 hours), higher voltage ratings (25 V), or expanded operating temperature ranges. Selection depends on application requirements for reliability and thermal performance.

Q: Are all substitute parts physically compatible with the original PCB layout?

A: Yes. All substitute parts maintain identical lead spacing (0.295" / 7.50 mm) and case diameter (0.630" / 16.00 mm). Maximum height increases slightly from 1.299" to 1.319" on all substitutes. Verify vertical clearance in the target application before assembly.

Q: Which substitute parts carry AEC-Q200 automotive qualification?

A: The following parts are AEC-Q200 certified: 16RX303300M16X31.5 (Rubycon), B41895B5338M (EPCOS - TDK Electronics), B41896C4338M (EPCOS - TDK Electronics), EEU-TP1E332 (Panasonic), EGXE160ELL332MLN3S (Chemi-Con), MAL214656332E3 (Vishay), and MAL214666332E3 (Vishay). Use AEC-Q200 certified parts for automotive applications.

Q: What is the significance of the lifetime specification (hours at temperature)?

A: Lifetime specification indicates the expected operational duration at the stated temperature before capacitance degradation reaches specified limits. The original 338HSM016M specifies 2000 hours at 125°C. Upgraded substitutes offer 4000 to 7000 hours, providing extended service life in high-temperature environments.

Q: Can I substitute the 338HSM016M with a part rated for a lower voltage?

A: No. A capacitor rated for lower voltage than the circuit operating voltage will fail prematurely or catastrophically. All substitute parts maintain the original 16 V minimum rating or higher.

Q: What does RoHS3 compliance indicate?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All active substitute parts listed are RoHS3 compliant.

Q: Are there differences in ripple current handling between the original and substitutes?

A: Yes. Ripple current specifications vary by manufacturer and series. The original 338HSM016M handles 1.33 A at 120 Hz and 1.6625 A at 10 kHz. Substitute parts range from 1.395 A to 2.6 A at 120 Hz. Higher ripple current capability indicates improved thermal performance under AC stress conditions.

Q: What does "Obsolete" product status mean for the 338HSM016M?

A: Obsolete status indicates the manufacturer has discontinued production and no longer supports the part. Existing inventory may be available from distributors, but long-term supply is not guaranteed. Substitution with active products ensures design continuity and future availability.
