SXR152M025ST Equivalent & Substitute Parts

Part Overview

The SXR152M025ST is a 1500 µF, 25 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in radial, can package configuration. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support, maintenance, and new design implementations where this specification remains applicable.

The SXR series represents a general-purpose aluminum electrolytic capacitor line designed for through-hole mounting applications. As product status transitions to obsolete, active equivalent parts from other manufacturers become necessary to maintain supply chain continuity and ensure long-term component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SXR152M025ST is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 1500 µF (exact match required)
• Tolerance: ±20% (electrical specification tolerance)
• Polarization: Polar (installation polarity requirement)
• Mounting Type: Through Hole (assembly compatibility)
• Package / Case: Radial, Can (physical form factor)
• Lead Spacing: 0.197" (5.00mm) (PCB footprint compatibility)
• Operating Temperature Range: -40°C ~ 105°C (environmental specification)

Allowable Parameter Variations:

• Voltage - Rated: Substitute parts may have equal or higher voltage ratings. A higher voltage rating provides additional safety margin and is electrically compatible with circuits designed for 25 V operation.
• Physical Dimensions (Diameter, Height): Minor variations are acceptable provided the component fits within the available PCB space and does not create mechanical interference.
• ESR, Ripple Current, Lifetime @ Temperature: These performance characteristics may differ between manufacturers while maintaining functional equivalence for general-purpose applications.

The EEU-FM1V152L from Panasonic Electronic Components meets all mandatory matching parameters and represents an active, in-stock equivalent part with a higher voltage rating (35 V) and improved performance characteristics.

Engineering Selection Recommendations

Primary Substitute: EEU-FM1V152L

The EEU-FM1V152L from Panasonic Electronic Components is the recommended equivalent part for the obsolete SXR152M025ST. Selection is based on the following engineering criteria:

Compliance and Regulatory Status:

• Both parts are ROHS3 compliant, ensuring regulatory alignment for current manufacturing and distribution standards.
• The EEU-FM1V152L carries active product status with confirmed inventory availability (1165 pcs in stock), providing supply chain security.

Electrical Compatibility:

• Capacitance and tolerance specifications are identical (1500 µF ±20%).
• The 35 V voltage rating of the EEU-FM1V152L exceeds the 25 V requirement of the original circuit, providing additional operational margin without introducing electrical incompatibility.
• Polar configuration and operating temperature range (-40°C ~ 105°C) match exactly.

Physical and Mechanical Compatibility:

• Lead spacing (0.197" / 5.00mm) is identical, ensuring PCB footprint compatibility.
• Physical dimensions show minor variations: diameter increases from 12.00mm to 12.50mm, and height increases from 30.00mm to 37.00mm. These variations require verification of available PCB space and clearance above the board surface to confirm mechanical fit within the target application.

Performance Characteristics:

• The EEU-FM1V152L demonstrates improved performance metrics compared to the original part, including higher ripple current ratings and extended lifetime at rated temperature (7000 Hrs @ 105°C versus 4000 Hrs @ 105°C).

Frequently Asked Questions (FAQ)

Q: Can the EEU-FM1V152L be used as a direct replacement for the SXR152M025ST?

A: The EEU-FM1V152L is electrically and functionally equivalent for circuits designed for the SXR152M025ST. However, physical dimensions differ: the substitute is 0.02" (0.50mm) larger in diameter and 0.276" (7.00mm) taller. Verify that available PCB space and clearance above the board accommodate these dimensional differences before installation.

Q: Why does the substitute part have a higher voltage rating (35 V vs. 25 V)?

A: A higher voltage rating does not create incompatibility in circuits designed for lower voltages. The 35 V rating of the EEU-FM1V152L provides additional safety margin and is fully compatible with 25 V circuit operation. The capacitor will function correctly at any voltage up to and including its rated maximum.

Q: Are there any performance differences between the original and substitute parts?

A: Yes. The EEU-FM1V152L offers improved performance: higher ripple current capacity (3 A @ 120 Hz and 3.75 A @ 100 kHz versus 770 mA @ 120 Hz and 1.54 A @ 100 kHz) and extended lifetime at rated temperature (7000 Hrs @ 105°C versus 4000 Hrs @ 105°C). These improvements enhance reliability and operational margin in the target application.

Q: What is the significance of the lead spacing specification?

A: Lead spacing (0.197" / 5.00mm) determines PCB hole pattern compatibility. Both the original and substitute parts share identical lead spacing, confirming that the component will fit existing PCB footprints without modification.

Q: Is the EEU-FM1V152L currently available?

A: Yes. The EEU-FM1V152L is classified as active product status with 1165 pcs confirmed in stock, ensuring immediate availability for procurement and assembly operations.

Q: What compliance certifications apply to the substitute part?

A: The EEU-FM1V152L is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution in regulated markets.

Q: Are there dimensional constraints I should consider before selecting this substitute?

A: Yes. The EEU-FM1V152L is physically larger than the original part (diameter: 12.50mm vs. 12.00mm; height: 37.00mm vs. 30.00mm). Confirm that the target PCB has sufficient space and vertical clearance above the board surface to accommodate the substitute component without mechanical interference or contact with adjacent components.
