2SLE100M Equivalent & Substitute Parts Reference

Part Overview

The 2SLE100M is a 100 µF, 2 V aluminum polymer capacitor manufactured by Rubycon in the 2917 (7343 Metric) surface mount package. This component is classified as obsolete, making substitute parts necessary for ongoing production and maintenance applications. The part delivers 9 mOhm ESR with a 2000-hour lifetime rating at 105°C, suitable for general-purpose applications requiring compact form factors and low equivalent series resistance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SLE100M is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Capacitance: 100 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Type: Polymer (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or greater than 2 V (higher voltage ratings are acceptable in applications requiring 2 V operation)
• ESR (Equivalent Series Resistance): May be equal to or lower than 9 mOhm (lower ESR values are acceptable)
• Ripple Current @ High Frequency: May be equal to or greater than 3 A @ 100 kHz (higher ripple current ratings are acceptable)
• Lifetime @ Temperature: May be equal to or greater than 2000 Hrs @ 105°C (longer lifetime ratings are acceptable)
• Height - Seated (Max): May be equal to or less than 0.055" (1.40mm) (lower height values are acceptable)

The EEF-CT0J101R from Panasonic Electronic Components qualifies as a substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CT0J101R qualifies as a direct substitute for the obsolete 2SLE100M based on electrical and mechanical parameter alignment. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory consistency in applications requiring the original part.

The Panasonic EEF-CT0J101R offers improved electrical characteristics: a higher voltage rating (6.3 V versus 2 V) provides additional design margin in applications operating at 2 V, and the increased ripple current rating (5.1 A versus 3 A @ 100 kHz) supports higher current environments. The ESR increase from 9 mOhm to 15 mOhm remains within acceptable tolerance for general-purpose applications.

The EEF-CT0J101R is classified as Active, ensuring continued availability and supply chain stability compared to the obsolete 2SLE100M.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CT0J101R replace the 2SLE100M in all applications?

A: The EEF-CT0J101R is electrically and mechanically compatible with the 2SLE100M for applications operating at 2 V. The higher voltage rating and improved ripple current capability make it suitable for general-purpose use. Verify that the application does not depend on the specific ESR value of 9 mOhm; the EEF-CT0J101R's 15 mOhm ESR is acceptable for most general-purpose circuits.

Q: What is the difference in height between these two parts?

A: The 2SLE100M has a maximum seated height of 0.055" (1.40mm), while the EEF-CT0J101R measures 0.059" (1.50mm). This 0.004" (0.10mm) difference is negligible for most PCB layouts and does not affect the 2917 (7343 Metric) package footprint compatibility.

Q: Why does the EEF-CT0J101R have a higher voltage rating?

A: The 6.3 V rating on the EEF-CT0J101R provides design margin and flexibility for applications that may require higher voltage operation. In 2 V applications, the part operates well within its voltage specification, ensuring reliability and extended component life.

Q: Are both parts RoHS compliant?

A: Yes, both the 2SLE100M and EEF-CT0J101R are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the packaging difference between these parts?

A: The 2SLE100M is supplied in standard packaging, while the EEF-CT0J101R is available in Tape & Reel (TR) format. Both use the same 2917 (7343 Metric) surface mount package and are compatible with automated assembly equipment.
