SXR152M016ST Equivalent & Substitute Parts Reference

Part Overview

The SXR152M016ST is a 1500 µF, 16 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in radial, through-hole configuration. This component is classified as obsolete, indicating it is no longer in active production. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 4000 hours at 105°C. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for ongoing design support, production continuity, and long-term component availability.

Substitute Part Grouping Explanation

Substitution of the SXR152M016ST is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Capacitance: 1500 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: Minimum 16 V (equal or higher voltage rating is acceptable)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)
Lead Spacing: 5.00 mm (exact match required)
Polarization: Polar (exact match required)

Secondary Compatibility Parameters:

Operating Temperature Range: Must encompass or exceed -40°C to 105°C
Physical Dimensions: Diameter and height must be compatible with PCB layout constraints
RoHS Compliance: ROHS3 Compliant status maintained

Substitute parts are grouped into two categories:

Upgrade Substitutes (Higher Voltage Rating): Parts rated at 25 V or higher provide voltage margin above the original 16 V specification. These parts maintain identical capacitance, tolerance, lead spacing, and mounting configuration while offering improved reliability through higher voltage headroom.

Similar Substitutes (Higher Voltage Rating): Parts rated at 35 V represent a higher voltage tier suitable for applications requiring additional voltage margin or where 25 V alternatives are unavailable.

All substitute parts listed maintain ROHS3 compliance and through-hole radial configuration with 5.00 mm lead spacing.

Engineering Selection Recommendations

For Active Production and New Designs:

The EEU-FC1E152 (Panasonic) and EKY-250ELL152MK25S (Chemi-Con) are the primary recommended substitutes. Both parts are classified as Active and maintain ROHS3 compliance. The EEU-FC1E152 carries AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability. The EKY-250ELL152MK25S offers extended lifetime (10000 hours at 105°C) compared to the original part (4000 hours), providing improved long-term reliability.

The EKZE250ELL152MK25S (Chemi-Con) is an alternative active substitute with the highest ripple current capability (2.77 A @ 100 kHz) and lowest impedance (18 mOhms), beneficial for high-ripple-current applications.

For Legacy System Support:

The UHE1E152MHD (Nichicon) and UPW1E152MHD6 (Nichicon) are classified as "Not For New Designs" but remain available for legacy system maintenance. These parts maintain compatibility with existing designs and are suitable for repair and replacement scenarios where design changes are not feasible.

For Higher Voltage Margin Applications:

The EEU-FM1V152L (Panasonic) rated at 35 V provides the highest voltage margin above the original 16 V specification. This part is suitable for applications where additional voltage headroom is required or where 25 V alternatives are unavailable. Note that this part has a maximum seated height of 37.00 mm, which may require PCB layout verification.

Physical Dimension Considerations:

The original SXR152M016ST has a diameter of 12.00 mm and height of 25.00 mm. Most substitute parts have a diameter of 12.50 mm (0.5 mm larger) and heights ranging from 25.00 mm to 37.00 mm. PCB layout verification is required to confirm clearance for parts with increased dimensions.

Frequently Asked Questions (FAQ)

Q1: Can I use a 25 V rated capacitor in place of the 16 V SXR152M016ST?

Yes. A higher voltage rating is electrically compatible and provides voltage margin. The 25 V substitutes (EEU-FC1E152, EKY-250ELL152MK25S, EKZE250ELL152MK25S, UHE1E152MHD, UPW1E152MHD6) are direct functional replacements. The circuit will operate normally at 16 V or below with a 25 V rated capacitor.

Q2: What is the difference between "Active" and "Not For New Designs" product status?

"Active" status indicates the manufacturer continues production and supports the part for new designs. "Not For New Designs" indicates the manufacturer maintains production for legacy support only and does not recommend the part for new circuit designs. For new designs, select parts with "Active" status: EEU-FC1E152, EKY-250ELL152MK25S, EKZE250ELL152MK25S, or EEU-FM1V152L.

Q3: Why do some substitute parts have different physical dimensions?

Substitute parts from different manufacturers may have slightly different case sizes while maintaining the same electrical specifications. The original SXR152M016ST has a 12.00 mm diameter; most substitutes have 12.50 mm diameter. Height varies from 25.00 mm to 37.00 mm depending on voltage rating and manufacturer design. Verify PCB layout clearance before substitution.

Q4: What does ROHS3 compliance mean?

ROHS3 (Restriction of Hazardous Substances Directive 3) compliance indicates the component meets European environmental regulations restricting hazardous materials. All listed substitute parts maintain ROHS3 compliance, ensuring regulatory compatibility with modern manufacturing and environmental standards.

Q5: Which substitute part offers the best reliability for long-term operation?

The EKY-250ELL152MK25S and UHE1E152MHD both offer 10000 hours lifetime at 105°C, compared to the original part's 4000 hours. For active production, the EKY-250ELL152MK25S is preferred due to its Active product status. The EKY-250ELL152MK25S also offers lower impedance (27 mOhms) and higher ripple current capability.

Q6: Can I use the EEU-FM1V152L (35 V) instead of a 25 V substitute?

Yes. The 35 V rated EEU-FM1V152L is electrically compatible and provides the highest voltage margin. However, this part has a maximum seated height of 37.00 mm, which is 12 mm taller than the original part. PCB layout verification is mandatory to confirm vertical clearance before substitution.

Q7: What is the significance of ESR (Equivalent Series Resistance) and impedance values?

ESR and impedance affect ripple current handling and heat generation. Lower values indicate better performance under high-ripple-current conditions. The EKZE250ELL152MK25S has the lowest impedance (18 mOhms) among substitutes, making it optimal for applications with high ripple current requirements. The original part has 150 mOhm ESR @ 120 Hz; substitutes range from 12 to 30 mOhms, providing improved performance.

Q8: Are all substitute parts available in the same packaging as the original?

All listed substitute parts are through-hole radial configuration with 5.00 mm lead spacing, matching the original SXR152M016ST mounting type and package style. Packaging format (Bulk) is consistent across all substitutes. No surface-mount alternatives are provided.

Q9: Which substitute should I select for automotive applications?

The EEU-FC1E152 (Panasonic) carries AEC-Q200 automotive qualification, making it the recommended choice for automotive applications. This part is Active, ROHS3 compliant, and rated at 25 V with 5000 hours lifetime at 105°C.

Q10: What is the lead spacing and why is it important?

Lead spacing is the distance between the two radial leads: 5.00 mm (0.197 inches). This dimension is critical for PCB footprint compatibility. All substitute parts maintain 5.00 mm lead spacing, ensuring direct PCB compatibility without layout modifications.
