Rubycon 2SLG180M1.4X7.3 Equivalent & Substitute Parts

Part Overview

The Rubycon 2SLG180M1.4X7.3 is a 180 µF, 2 V aluminum polymer surface mount capacitor in the 2917 (7343 Metric) package. This component is classified as Not For New Designs, indicating it has been superseded in Rubycon's product portfolio. The part operates across a temperature range of -55°C to 105°C with a 2000-hour lifetime rating at 105°C. Finding equivalent substitute parts is necessary for applications requiring continued supply, design flexibility, or performance optimization while maintaining the same physical footprint and electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2SLG180M1.4X7.3 is determined by the following critical parameters:

• Capacitance: Must be 180 µF (±20% tolerance acceptable)
• Package: Must be 2917 (7343 Metric) to ensure physical compatibility with existing PCB layouts
• Mounting Type: Must be Surface Mount
• Type: Aluminum Polymer construction
• Operating Temperature Range: Must support -55°C to 105°C minimum
• Compliance: RoHS3 compliance required

The Panasonic EEF-CX0J181R meets all substitution criteria. While it features a higher voltage rating (6.3 V vs. 2 V) and different ESR (15 mOhm vs. 9 mOhm), these parameters do not prevent substitution in applications designed for the original part. The higher voltage rating provides additional design margin, and the identical capacitance, package, and temperature range ensure functional compatibility.

Engineering Selection Recommendations

The Panasonic EEF-CX0J181R is the qualified substitute for the Rubycon 2SLG180M1.4X7.3. Selection should be based on the following factors:

• Product Status: The Panasonic part carries Active status, ensuring long-term availability and supply continuity compared to the Rubycon part's Not For New Designs classification.
• Compliance: Both parts maintain ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements for current manufacturing standards.
• Physical Compatibility: Identical package dimensions (2917 / 7343 Metric) and mounting type ensure direct PCB layout compatibility without redesign.
• Electrical Compatibility: Matching capacitance and tolerance values maintain circuit performance. The higher voltage rating of the Panasonic part provides additional operational margin without adverse effects in applications designed for 2 V operation.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic EEF-CX0J181R directly replace the Rubycon 2SLG180M1.4X7.3 on existing PCBs?

A: Yes. Both parts use the identical 2917 (7343 Metric) package with matching physical dimensions and surface mount land patterns. No PCB modifications are required.

Q: Why does the Panasonic substitute have a higher voltage rating (6.3 V vs. 2 V)?

A: Higher voltage ratings do not prevent substitution. The Panasonic part operates safely in circuits designed for 2 V operation. The additional voltage margin may improve reliability in applications with voltage transients.

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

A: Yes. The Rubycon part specifies 9 mOhm ESR, while the Panasonic part specifies 15 mOhm ESR at 100 kHz. Both values are within acceptable ranges for general-purpose aluminum polymer capacitors. Applications sensitive to ESR should evaluate the impact of this 6 mOhm difference.

Q: Do both parts meet current compliance standards?

A: Yes. Both the Rubycon 2SLG180M1.4X7.3 and Panasonic EEF-CX0J181R are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

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

A: This designation indicates the part has been superseded in Rubycon's product line. While existing inventory may be available, Rubycon does not recommend its use in new designs. The Panasonic substitute, with Active status, is the preferred choice for ongoing and future applications.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across -55°C to 105°C with a 2000-hour lifetime rating at 105°C, ensuring equivalent thermal performance.
