SXR332M025ST Equivalent & Substitute Parts

Part Overview

The SXR332M025ST is a 3300 µF, 25 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in radial, can package configuration. This component is classified as obsolete, indicating that the original manufacturer has discontinued production. The SXR series operates across a temperature range of -40°C to 105°C with a rated lifetime of 5000 hours at 105°C, making it suitable for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Due to the obsolete status of the SXR332M025ST, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for production and field replacement applications.

Mandatory Equivalence Parameters:

Capacitance: 3300 µF (exact match required)
Voltage Rating: 25 V (exact match required)
Tolerance: ±20% (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)
Lead Spacing: 7.50 mm (exact match required)
Case Diameter: 16.00 mm (exact match required)
Polarization: Polar (exact match required)

Compatible Parameter Ranges:

Operating Temperature Range: Must encompass or equal -40°C to 105°C minimum
Lifetime @ 105°C: Substitute parts with 10000 hours provide extended reliability compared to the original 5000 hours

Frequently Asked Questions (FAQ)

Q: Can the SXR332M025ST be directly replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts are electrically and mechanically equivalent to the SXR332M025ST. They share identical capacitance (3300 µF), voltage rating (25 V), tolerance (±20%), lead spacing (7.50 mm), case diameter (16.00 mm), and mounting type (through-hole radial). Direct PCB substitution is supported without circuit redesign.

Q: What is the primary difference between the original SXR332M025ST and the substitute parts?

A: The original SXR332M025ST is obsolete with a 5000-hour lifetime at 105°C. Most substitute parts are active products with extended 10000-hour lifetime, providing improved reliability and longer service life. Additionally, many substitutes feature lower impedance values, resulting in reduced equivalent series resistance and improved high-frequency performance.

Q: Does the height difference between the original part (36.00 mm) and compact substitutes (27.00 mm) affect PCB compatibility?

A: Height differences do not affect electrical compatibility. Compact substitutes (27.00 mm height) occupy less vertical PCB space, which may be advantageous in space-constrained designs. The original height (36.00 mm) can be matched with ELXV250ELL332ML35S (36.50 mm) if vertical clearance is a design constraint. Lead spacing and case diameter remain identical across all substitutes, ensuring footprint compatibility.

Q: Which substitute part offers the best performance characteristics?

A: Performance depends on application requirements. For impedance-critical applications, 25ZLH3300MEFC16X25 offers the lowest impedance (13 mOhms). For ripple current handling, EEU-FR1E332 provides the highest ripple current at 100 kHz (3.82 A). For automotive applications, ELXV250ELL332ML35S includes AEC-Q200 certification and extended temperature range (-55°C to 105°C).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, meeting environmental and regulatory requirements equivalent to the original SXR332M025ST.

Q: Should UHE1E332MHD be used in new designs?

A: No. UHE1E332MHD carries a product status of "Not For New Designs." While electrically compatible and currently available, this part is designated for legacy support only. New designs should select from active-status alternatives such as 25ZLJ3300M16X25, 25ZLH3300MEFC16X25, EEU-FR1E332, or EKZN250ELL332ML25S.

Q: What inventory considerations should guide part selection?

A: 25ZLJ3300M16X25 offers the highest inventory availability (18,604 pcs), providing supply security for high-volume production. UHE1E332MHD also maintains substantial inventory (9,893 pcs) despite "Not For New Designs" status. Other active substitutes maintain adequate stock levels (744 to 6,550 pcs) for standard production requirements.

Q: Can substitute parts be mixed within a single assembly?

A: Yes. All substitute parts meet identical electrical specifications and are mechanically compatible. Mixed usage within a single assembly does not create compatibility issues. However, design documentation should reflect the specific part number used to maintain traceability and support field replacement procedures.
