SXR102M025ST Equivalent & Substitute Parts Reference

Part Overview

The SXR102M025ST is a 1000 µF, 25 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in radial, through-hole configuration. This component is classified as obsolete, indicating discontinued production and limited availability for new procurement. 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 obsolete status and finite inventory (799 pieces), identifying equivalent and substitute parts is necessary for design continuity, production planning, and long-term supply chain management. Substitute parts maintain the same capacitance and tolerance while offering improved availability, extended lifetime ratings, or higher voltage ratings for enhanced design margin.

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on substitution logic:

Upgrade Substitutes (Higher Voltage Rating): Parts rated at 35 V maintain the same 1000 µF capacitance and ±20% tolerance while providing increased voltage margin. These parts are electrically compatible in applications where the original 25 V rating is not a limiting constraint. All upgrade substitutes share identical lead spacing (5.00 mm) and through-hole mounting configuration, ensuring PCB footprint compatibility. Upgrade substitutes include:

EEU-EB1V102 (Panasonic, 35 V, 10000 Hrs @ 105°C)
EEU-FC1V102 (Panasonic, 35 V, 5000 Hrs @ 105°C)
EKY-350ELL102MK25S (Chemi-Con, 35 V, 10000 Hrs @ 105°C)
EKZE350ELL102MK25S (Chemi-Con, 35 V, 5000 Hrs @ 105°C)
UHD1V102MHD (Nichicon, 35 V, 5000 Hrs @ 105°C)
UHE1V102MHD (Nichicon, 35 V, 10000 Hrs @ 105°C)
UPW1V102MHD (Nichicon, 35 V, 7000 Hrs @ 105°C)

Similar Substitute (Same Voltage Rating): EEU-FR1E102 maintains the original 25 V rating with identical capacitance and tolerance. This part differs in physical dimensions and offers extended lifetime (10000 Hrs @ 105°C) with active product status.

Key parameters determining substitution eligibility:

Capacitance: 1000 µF (fixed requirement)
Tolerance: ±20% (fixed requirement)
Lead Spacing: 0.197" / 5.00 mm (PCB compatibility)
Mounting Type: Through Hole, Radial (form factor compatibility)
Polarization: Polar (electrical requirement)

Frequently Asked Questions (FAQ)

Q: Can I use a 35 V rated capacitor in place of the original 25 V SXR102M025ST?

A: Yes. A 35 V rated capacitor is electrically compatible in any application designed for 25 V operation. The higher voltage rating provides additional safety margin and does not affect circuit performance. All 35 V substitutes listed maintain identical capacitance (1000 µF), tolerance (±20%), lead spacing (5.00 mm), and through-hole mounting configuration.

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

A: Active status indicates the manufacturer continues production and supports the part for new designs. "Not For New Designs" status indicates the manufacturer has discontinued active support but may maintain limited production for existing customers. For new designs, select parts with Active status: EEU-EB1V102, EEU-FC1V102, EKY-350ELL102MK25S, EKZE350ELL102MK25S, UPW1V102MHD, or EEU-FR1E102.

Q: Does the physical size difference between substitutes affect PCB compatibility?

A: Lead spacing (5.00 mm) is identical across all substitutes and the original part, ensuring PCB footprint compatibility. Height variations (22.00 mm to 27.00 mm) may affect clearance in space-constrained applications. For identical height to the original (25.00 mm), select EEU-FC1V102, UHD1V102MHD, UHE1V102MHD, or UPW1V102MHD. For reduced height (22.00 mm), EEU-FR1E102 is suitable if vertical clearance is limited.

Q: Which substitute offers the longest service life?

A: EEU-EB1V102, EKY-350ELL102MK25S, and EEU-FR1E102 all provide 10000 Hrs @ 105°C lifetime, which is 2.5 times longer than the original SXR102M025ST (4000 Hrs @ 105°C). UPW1V102MHD provides 7000 Hrs @ 105°C as an intermediate option.

Q: Is EEU-FR1E102 a direct replacement for the SXR102M025ST?

A: EEU-FR1E102 maintains the same 25 V voltage rating and 1000 µF capacitance as the original part. However, it differs in physical dimensions (smaller diameter and height) and offers extended lifetime (10000 Hrs vs. 4000 Hrs). Verify PCB clearance before substitution due to dimensional differences.

Q: What does "ROHS3 Compliant" mean for these capacitors?

A: ROHS3 Compliant indicates the part meets Restriction of Hazardous Substances Directive 3 requirements, restricting lead, mercury, cadmium, hexavalent chromium, and specified brominated flame retardants. All listed substitutes are ROHS3 compliant, ensuring regulatory compliance for EU and equivalent markets.

Q: Can I mix different substitute part numbers in the same circuit board?

A: Yes. All substitute parts maintain identical capacitance (1000 µF), tolerance (±20%), lead spacing (5.00 mm), and through-hole mounting. They are electrically and mechanically interchangeable. However, for manufacturing consistency and supply chain simplification, using a single part number per design is recommended.

Q: Which substitute has the highest inventory availability?

A: EEU-FR1E102 (Panasonic) has the highest inventory with 1,000,400 units in stock. For 35 V rated alternatives, EEU-FC1V102 (Panasonic) has 105,693 units in stock.
