SXR332M016ST Equivalent & Substitute Parts Reference

Part Overview

The SXR332M016ST is a 3300 µF, 16 V aluminum electrolytic capacitor in radial can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, with 773 units currently in stock. The part is designed for general-purpose applications requiring stable capacitance and reliable performance across industrial temperature ranges.

Due to the obsolete status of the SXR332M016ST, equivalent substitute parts from active manufacturers are necessary for new designs, production continuity, and long-term component availability. The substitute parts listed maintain the same electrical specifications (3300 µF capacitance, 16 V rated voltage, ±20% tolerance) and mechanical compatibility (radial through-hole mounting, 5.00 mm lead spacing) while offering extended operational lifetimes and improved performance characteristics.

Engineering Selection Recommendations

Product Status Consideration: The SXR332M016ST is classified as obsolete. All listed substitute parts are manufactured by active suppliers (Rubycon, Panasonic Electronic Components, Chemi-Con) with active product status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: All substitute parts maintain ROHS3 compliance, matching the regulatory status of the original component. This ensures compatibility with current manufacturing standards and environmental regulations.

Mechanical Compatibility: All substitute parts feature identical lead spacing (5.00 mm) and through-hole radial mounting configuration. However, physical dimensions vary:

Compact options (27.00 mm height): 16YXJ3300M12.5X25, EEU-FS1C332, EKYA160ELL332MK25S, EKYB160ELL332MK25S
Standard options (32.00-37.00 mm height): 16ZLH3300MEFC12.5X30, 16ZLJ3300M12.5X30, 16ZLS3300MEFC12.5X30, EEU-FM1C332L, EEU-FR1C332L, EKY-160ELL332MK35S

PCB layout verification is required to confirm that selected substitute parts fit within available vertical clearance constraints.

Performance Characteristics: Substitute parts demonstrate improved electrical performance compared to the obsolete SXR332M016ST:

Impedance reduction: 80 mOhms (original) to 12-32 mOhms (substitutes)
Lifetime extension: 4000 hours (original) to 6000-10000 hours (substitutes)
Enhanced ripple current handling: 1.19 A @ 120 Hz (original) to 1.67-3.00 A @ 120 Hz (substitutes)

These improvements provide superior reliability and thermal stability in operational circuits.

Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts be used interchangeably with the SXR332M016ST?

A: All listed substitute parts meet the critical electrical and mechanical parameters required for direct substitution: 3300 µF capacitance, 16 V voltage rating, ±20% tolerance, 5.00 mm lead spacing, and through-hole radial mounting. However, physical height differences require PCB layout verification before implementation. Compact variants (27.00 mm) may not fit in enclosures designed for the original 40.00 mm height, while standard variants (32.00-37.00 mm) provide closer dimensional compatibility.

Q: What is the significance of impedance and ESR differences between the original and substitute parts?

A: The original SXR332M016ST specifies 80 mOhms ESR at 120 Hz. Substitute parts exhibit lower impedance values (12-32 mOhms), which reduces voltage ripple, heat generation, and improves circuit stability. Lower impedance is a performance enhancement that does not compromise substitution eligibility.

Q: Why do substitute parts have longer operational lifetimes?

A: The original SXR332M016ST is rated for 4000 hours at 105°C. Substitute parts from active manufacturers (Rubycon, Panasonic, Chemi-Con) are rated for 6000-10000 hours at 105°C. Extended lifetime reflects modern manufacturing improvements and does not indicate incompatibility; it represents superior reliability for new designs.

Q: Are there any height restrictions I should consider when selecting a substitute?

A: Yes. The original SXR332M016ST has a maximum seated height of 40.00 mm. Substitute parts range from 26.50 mm to 37.00 mm. If your PCB assembly has vertical clearance constraints (such as proximity to other components or enclosure lids), select substitute parts with appropriate height ratings. Compact options (26.50-27.00 mm) provide maximum clearance; standard options (32.00-37.00 mm) offer closer dimensional matching to the original.

Q: Do all substitute parts maintain the same lead spacing for PCB compatibility?

A: Yes. All substitute parts maintain 5.00 mm (0.197") lead spacing, ensuring compatibility with PCB hole patterns designed for the SXR332M016ST. No PCB redesign is required for lead spacing accommodation.

Q: What is the difference between Rubycon YXJ, ZLH, ZLJ, and ZLS series?

A: All Rubycon series maintain identical electrical specifications (3300 µF, 16 V, ±20% tolerance) and lead spacing. Differences are in physical dimensions and performance characteristics: YXJ and ZLS series offer compact heights (27.00 mm and 32.00 mm respectively), while ZLH and ZLJ series provide standard heights (32.00 mm). ZLS series is rated for 6000 hours at 105°C, while YXJ, ZLH, and ZLJ are rated for 10000 hours. Selection depends on available PCB space and required operational lifetime.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant, matching the regulatory status of the original SXR332M016ST. This ensures compatibility with current manufacturing standards and environmental regulations across all markets.

Q: Can I use a substitute part with higher ripple current rating in a circuit designed for the original part?

A: Yes. Substitute parts with higher ripple current ratings (up to 3.00 A @ 120 Hz compared to the original 1.19 A @ 120 Hz) are fully compatible and provide enhanced performance margin. Higher ripple current capability indicates improved thermal stability and does not create circuit incompatibility.
