2SLG100M1.4X7.3 Equivalent & Substitute Parts

Part Overview

The 2SLG100M1.4X7.3 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 This component is classified as Not For New Designs, indicating it has been superseded in Rubycon's product line. The part is suitable for general purpose applications requiring low ESR characteristics and stable performance across the -55°C to 105°C operating temperature range. Identifying equivalent substitute parts is necessary for applications where the original part is no longer available or where design flexibility is required.

Substitute Part Grouping Explanation

Substitution of the 2SLG100M1.4X7.3 is determined by the following critical parameters:

• Capacitance Value: Must be 100 µF
• Package Type: Must be 2917 (7343 Metric) to ensure mechanical and electrical compatibility
• Voltage Rating: Must be equal to or greater than 2 V
• Type: Must be Aluminum Polymer to maintain electrical characteristics
• Mounting Type: Must be Surface Mount
• Operating Temperature Range: Must encompass -55°C ~ 105°C
• Lifetime Rating: Must meet or exceed 2000 Hrs @ 105°C
• Compliance: Must maintain ROHS3 compliance

The substitute part EEF-CX0J101R from Panasonic Electronic Components meets all substitution criteria. The higher voltage rating (6.3 V vs. 2 V) and increased ESR (15 mOhm vs. 9 mOhm) are acceptable variations that do not compromise functionality in general purpose applications where the original 2 V rating is sufficient.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0J101R is a direct substitute for the 2SLG100M1.4X7.3 based on the following factors:

• Both parts maintain identical capacitance, tolerance, package dimensions, and operating temperature range
• The substitute part carries Active product status, ensuring continued availability and supply chain stability
• Both parts are ROHS3 compliant and meet identical regulatory requirements
• The higher voltage rating of the substitute part (6.3 V) provides additional design margin without compromising performance in applications rated for 2 V operation
• The increased ripple current capability (5.1 A vs. 2.7 A) of the substitute part offers improved performance headroom

Selection of the EEF-CX0J101R is appropriate for new designs and replacement applications where the original 2SLG100M1.4X7.3 is unavailable.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0J101R be used as a direct replacement for the 2SLG100M1.4X7.3?

A: Yes. Both parts share identical capacitance, tolerance, package type, and operating temperature specifications. The substitute part is mechanically and electrically compatible for surface mount applications.

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

A: The EEF-CX0J101R is rated for 6.3 V, compared to the original 2 V rating. In applications where the circuit voltage does not exceed 2 V, the higher voltage rating of the substitute part does not affect performance and provides additional design margin.

Q: Are there differences in ESR between the two parts?

A: The substitute part has an ESR of 15 mOhm compared to 9 mOhm for the original part. This difference is acceptable for general purpose applications and does not impact functionality in circuits designed for the original 2 V, 100 µF specification.

Q: Do both parts have the same physical dimensions?

A: Both parts use the 2917 (7343 Metric) package with identical length and width (7.30mm x 4.30mm). The substitute part has a slightly greater seated height (1.90mm vs. 1.10mm), which must be verified against PCB layout constraints.

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

A: This designation indicates the 2SLG100M1.4X7.3 has been superseded by Rubycon and is no longer recommended for new product development. The EEF-CX0J101R, with Active status, is the appropriate choice for ongoing and new applications.
