SXR101M025ST Equivalent & Substitute Parts

Part Overview

The SXR101M025ST is a 100 µF, 25 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part operates across a temperature range of -40°C to 105°C and is rated for 3000 hours at 105°C. Substitution is required due to product discontinuation while maintaining compatibility with general-purpose circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SXR101M025ST is determined by the following critical parameters that must remain constant or be exceeded:

Mandatory Matching Parameters:

• Capacitance: 100 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can (exact match required)
• Lead Spacing: 0.138" (3.50 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -40°C to 105°C (minimum requirement)

Allowable Parameter Upgrades:

• Voltage Rating: Substitute parts rated at 63 V exceed the original 25 V specification, providing enhanced voltage margin and circuit protection
• Lifetime @ Temperature: Substitute parts rated at 8000 hours or 10000 hours at 105°C exceed the original 3000-hour specification, providing extended operational life

Both substitute parts (EEU-FR1J101L and EEU-EB1J101) meet all mandatory matching criteria and provide improvements in voltage rating and thermal lifetime, making them suitable replacements for the obsolete SXR101M025ST.

Engineering Selection Recommendations

EEU-EB1J101 (Recommended Primary Substitute)

The EEU-EB1J101 is the preferred substitute for the SXR101M025ST. This Panasonic component carries active product status, ensuring long-term availability and supply chain continuity. The part maintains identical capacitance, tolerance, and package dimensions while providing a 63 V voltage rating and 10000-hour lifetime at 105°C. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The increased voltage rating provides additional circuit protection margin, and the extended thermal lifetime supports applications requiring enhanced reliability.

EEU-FR1J101L (Alternative Substitute)

The EEU-FR1J101L serves as an alternative substitute with active product status. This part provides the same capacitance and tolerance specifications with a 63 V voltage rating and 8000-hour lifetime at 105°C. Both substitute options are ROHS3 compliant and suitable for direct replacement in through-hole applications. The selection between EEU-EB1J101 and EEU-FR1J101L depends on application-specific requirements for thermal lifetime and ripple current handling capacity.

Frequently Asked Questions (FAQ)

Q: Can the EEU-EB1J101 or EEU-FR1J101L be used as direct replacements for the SXR101M025ST?

A: Yes. Both substitute parts maintain identical capacitance (100 µF), tolerance (±20%), polarization (polar), package type (radial, can), lead spacing (0.138" / 3.50 mm), and mounting type (through hole). The substitute parts are physically and electrically compatible with the original component in through-hole circuit applications.

Q: Why do the substitute parts have a higher voltage rating (63 V vs. 25 V)?

A: The higher voltage rating is an allowable upgrade that does not compromise compatibility. A 63 V rated capacitor operates safely at 25 V and below, providing additional voltage margin and circuit protection. This upgrade is standard practice in component substitution when the original part becomes obsolete.

Q: What is the difference between the EEU-EB1J101 and EEU-FR1J101L?

A: Both parts share identical capacitance, tolerance, voltage rating, and package specifications. The primary differences are thermal lifetime (10000 hours vs. 8000 hours at 105°C) and ripple current ratings. The EEU-EB1J101 provides extended thermal life, while the EEU-FR1J101L offers higher ripple current capacity at both low and high frequencies.

Q: Are there any height differences that affect PCB layout?

A: The substitute parts have a maximum seated height of 0.650" (16.50 mm) compared to the original 0.630" (16.00 mm). This 0.020" (0.50 mm) increase is negligible for most applications but should be verified if the component is mounted in space-constrained environments or near other tall components.

Q: Do the substitute parts meet current compliance standards?

A: Yes. Both EEU-EB1J101 and EEU-FR1J101L are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in most markets.

Q: What is the operating temperature range for the substitute parts?

A: Both substitute parts operate across -40°C to 105°C, matching the original SXR101M025ST specification and supporting the same thermal operating envelope.
