Equivalent & Substitute Parts for 2SLE100M1.4X7.3

Part Overview

The Rubycon 2SLE100M1.4X7.3 is a 100 µF, 2 V aluminum polymer capacitor in the 2917 (7343 Metric) surface mount package. This component is classified as Not For New Designs, indicating it has been superseded in Rubycon's product portfolio. Finding equivalent substitute parts is necessary for applications requiring continued supply, legacy system maintenance, or design flexibility when the original part becomes unavailable.

Substitute Part Grouping Explanation

Substitution of aluminum polymer capacitors is determined by the following critical parameters:

Capacitance Value: Must match exactly at 100 µF
Package Footprint: Must be identical 2917 (7343 Metric) for PCB compatibility
Voltage Rating: Must be equal to or greater than 2 V
Type: Must be aluminum polymer construction
Operating Temperature Range: Must support -55°C ~ 105°C minimum
Mounting Type: Must be surface mount

The Panasonic EEF-CX0J101R meets all substitution criteria. While it features a higher voltage rating (6.3 V) and slightly different ESR and ripple current specifications, these parameters remain within acceptable ranges for general purpose applications and represent an upgrade in voltage capability without compromising footprint compatibility.

Engineering Selection Recommendations

The Panasonic EEF-CX0J101R is a direct functional substitute for the Rubycon 2SLE100M1.4X7.3. Both components are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial applications.

The primary distinction is product status: the Rubycon part is classified as Not For New Designs, while the Panasonic part is Active. For applications requiring continued supply or new designs, the Panasonic EEF-CX0J101R is the appropriate selection. The higher voltage rating (6.3 V versus 2 V) provides additional design margin without affecting PCB layout or thermal performance.

Physical height differs by 0.020" (0.50 mm), which may require verification in space-constrained applications. The increased ESR (15 mOhm versus 9 mOhm) and higher ripple current capability (5.1 A versus 3 A) are acceptable trade-offs for general purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic EEF-CX0J101R be used as a direct replacement on existing PCBs designed for the Rubycon 2SLE100M1.4X7.3?

A: Yes. Both components use the identical 2917 (7343 Metric) package with matching footprint dimensions (0.287" L x 0.169" W). The height difference of 0.020" is typically accommodated in standard PCB design clearances.

Q: Why does the substitute part have a higher voltage rating?

A: The Panasonic part is rated for 6.3 V versus 2 V on the Rubycon part. This represents a design upgrade that provides additional voltage margin. In applications operating at 2 V, the higher rating does not negatively impact performance and may improve reliability.

Q: Are there differences in electrical performance between these parts?

A: The ESR differs (15 mOhm versus 9 mOhm) and ripple current capability is higher on the Panasonic part (5.1 A versus 3 A at 100 kHz). Both maintain identical capacitance, tolerance, lifetime rating, and operating temperature range. The differences are within acceptable parameters for general purpose applications.

Q: What is the significance of the "Not For New Designs" status on the Rubycon part?

A: This designation indicates the part has been superseded in the manufacturer's product line. For new designs, the Panasonic EEF-CX0J101R is the recommended selection. For legacy applications, the Panasonic part provides continued supply with equivalent functionality.

Q: Are both parts RoHS compliant?

A: Yes. Both the Rubycon 2SLE100M1.4X7.3 and Panasonic EEF-CX0J101R are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial applications.
