SXR101M010ST Equivalent & Substitute Parts Reference

Part Overview

The SXR101M010ST is a 100 µF, 10 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete and is designed for general-purpose applications requiring through-hole mounting. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 2000 hours at 105°C.

Due to its obsolete status, equivalent and substitute parts are necessary for ongoing design support, production continuity, and component sourcing. Substitute parts are selected based on matching or exceeding the electrical and mechanical parameters of the original specification while maintaining compatibility with the application circuit.

Engineering Selection Recommendations

For Active Product Status Priority:

When sourcing replacements for the SXR101M010ST, preference should be given to active products to ensure long-term availability and supply chain stability. The following active substitutes meet or exceed the original specifications:

SEK101M016ST (Cornell Dubilier Electronics): Active status, same manufacturer as original, 16 V rating provides voltage margin, improved ESR of 2.39 Ohm, extended temperature range to -55°C, higher ripple current capability at 120 Hz (135 mA).
EEU-EB1E101S (Panasonic Electronic Components): Active status, 25 V rating, extended lifetime of 5000 hours at 105°C, ROHS3 compliant, operating temperature range -40°C to 105°C.
EKZE250ELL101MF11D (Chemi-Con): Active status, 25 V rating, 2000 hour lifetime at 105°C, superior ripple current handling at 100 kHz (405 mA), low impedance of 130 mOhms, ROHS3 compliant.

For Compliance and Certification:

All substitute parts listed are ROHS3 compliant and carry EAR99 ECCN classification, matching the regulatory status of the original part. Panasonic and Chemi-Con parts carry REACH Unaffected status, providing additional regulatory assurance.

For Mechanical Compatibility:

All substitutes maintain the 0.098" (2.50 mm) lead spacing required for PCB footprint compatibility. Case diameter increases from 6.00 mm to 6.30 mm are within acceptable mechanical tolerances for radial can packages. Height variations (11.00 mm to 12.20 mm) are within standard radial capacitor envelope specifications.

Frequently Asked Questions (FAQ)

Q: Can the SXR101M010ST be directly replaced with a higher voltage-rated substitute?

A: Yes. Substitutes with voltage ratings of 16 V or 25 V are electrically compatible with circuits designed for 10 V operation. The higher voltage rating provides additional safety margin and does not affect circuit performance. All mechanical parameters (lead spacing, case diameter, height) remain compatible with the original PCB footprint.

Q: What is the significance of the ESR (Equivalent Series Resistance) parameter in selecting a substitute?

A: ESR affects ripple current handling, thermal performance, and frequency response. The original SXR101M010ST specifies 2.52 Ohm @ 120 Hz. Substitutes with equal or lower ESR values (such as SEK101M016ST at 2.39 Ohm) provide improved performance. When ESR is not specified in substitute data, the part remains compatible but specific ripple current performance cannot be directly compared.

Q: Are obsolete substitute parts acceptable for new designs?

A: Obsolete substitute parts (517D107M025AA6AE3, UPW1C101MED, UHE1E101MED) are listed for reference and legacy system support only. For new designs, active products (SEK101M016ST, EEU-EB1E101S, EKZE250ELL101MF11D) are recommended to ensure long-term component availability and manufacturing continuity.

Q: How does the lifetime rating at 105°C affect part selection?

A: Lifetime rating indicates the expected operational duration under specified thermal stress. The original part specifies 2000 hours at 105°C. Substitutes with 5000-hour ratings (EEU-EB1E101S, UHE1E101MED) provide extended service life under high-temperature conditions. Both 2000-hour and 5000-hour parts are functionally compatible; the choice depends on application reliability requirements.

Q: What is the impact of case diameter increase from 6.00 mm to 6.30 mm?

A: The 0.30 mm diameter increase is within standard manufacturing tolerances for radial aluminum electrolytic capacitors and does not affect electrical performance. PCB footprint compatibility is maintained as lead spacing (2.50 mm) remains constant. Physical clearance around the component should be verified in space-constrained applications.

Q: Can substitutes with different ripple current ratings be used interchangeably?

A: Substitutes with equal or higher ripple current ratings are compatible. The original SXR101M010ST specifies 108 mA @ 120 Hz and 180 mA @ 100 kHz. All listed substitutes meet or exceed these values, indicating improved ripple current handling capability. Parts with lower ripple current ratings are not acceptable substitutes.

Q: What does ROHS3 compliance indicate?

A: ROHS3 compliance certifies that the component meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, hexavalent chromium, and specified flame retardants. All listed substitutes carry ROHS3 certification, ensuring regulatory compliance for applications subject to these restrictions.
