2SXE180M Equivalent & Substitute Parts

Part Overview

The 2SXE180M is a 180 µF, 2 V aluminum polymer capacitor manufactured by Rubycon in the 2917 (7343 Metric) surface mount package. This component is designed for general purpose applications requiring low ESR and stable performance across extended temperature ranges. The part is currently obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SXE180M is determined by the following critical parameters:

• Capacitance Value: 180 µF (exact match required)
• Package Footprint: 2917 (7343 Metric) (physical compatibility)
• Mounting Type: Surface Mount (assembly compatibility)
• Voltage Rating: Minimum 2 V (equal or higher acceptable)
• Type: Aluminum Polymer (electrical characteristics)
• Operating Temperature Range: -55°C ~ 105°C (environmental compatibility)

The EEF-CT0G181R from Panasonic meets all substitution criteria. While it features a higher voltage rating (4 V) and different ESR specification (15 mOhm), these parameters remain within acceptable substitution boundaries for general purpose applications. The identical package footprint, capacitance value, and temperature range ensure mechanical and electrical compatibility.

Engineering Selection Recommendations

The EEF-CT0G181R is the primary substitute for the obsolete 2SXE180M. Selection is justified on the following basis:

• Product Status: The EEF-CT0G181R maintains active production status, ensuring long-term availability and supply chain stability.
• Compliance: Both components are ROHS3 compliant and REACH unaffected, meeting regulatory requirements.
• Electrical Compatibility: Identical capacitance (180 µF) and matching package footprint (2917 / 7343 Metric) ensure direct replacement capability.
• Voltage Margin: The 4 V rating of the substitute exceeds the 2 V requirement, providing additional safety margin in circuit operation.
• Thermal Performance: Matching operating temperature range (-55°C ~ 105°C) and lifetime specification (2000 Hrs @ 105°C) ensure equivalent thermal behavior.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CT0G181R directly replace the 2SXE180M on the PCB?

A: Yes. Both components use the 2917 (7343 Metric) surface mount package with identical footprint dimensions (7.30mm L × 4.30mm W). No PCB layout modifications are required.

Q: What is the significance of the voltage rating difference (2 V vs. 4 V)?

A: The substitute's higher voltage rating (4 V) is acceptable for applications designed for 2 V operation. Higher voltage ratings provide additional safety margin and do not negatively impact circuit performance in lower voltage applications.

Q: How do the ESR values differ, and does this matter?

A: The 2SXE180M specifies 9 mOhm ESR, while the EEF-CT0G181R specifies 15 mOhm. For general purpose applications, this difference is within acceptable tolerance. Applications with strict ESR requirements should evaluate ripple current performance; the substitute supports higher ripple current (5.1 A vs. 3 A @ 100 kHz).

Q: Are there any compliance or certification differences?

A: Both components are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution.

Q: What is the availability status of each part?

A: The 2SXE180M is obsolete with limited remaining inventory. The EEF-CT0G181R is in active production with substantial inventory availability, making it the recommended long-term solution.
