2SLG150M Equivalent & Substitute Parts

Part Overview

The 2SLG150M is a 150 µF, 2 V aluminum polymer capacitor manufactured by Rubycon in the PC-CON and SLG series. This surface mount component is housed in a 2917 (7343 Metric) package with a maximum seated height of 1.10 mm and an ESR of 9 mOhm. The part is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SLG150M is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 150 µF (±20% tolerance acceptable)
• Package / Case: 2917 (7343 Metric)
• Mounting Type: Surface Mount
• Type: Aluminum Polymer

Allowable Variation Parameters:

• Voltage Rating: May be equal to or higher than the original 2 V rating
• ESR: May be equal to or lower than the original 9 mOhm specification
• Ripple Current: May be equal to or higher than the original 2.7 A @ 100 kHz
• Lifetime @ Temperature: May be equal to or higher than 2000 Hrs @ 105°C
• Height - Seated: Must not exceed the original 1.10 mm maximum to ensure PCB layout compatibility

The EEF-CX0G151R from Panasonic Electronic Components meets these substitution criteria with a higher voltage rating (4 V), lower ESR (15 mOhm), and higher ripple current capability (5.1 A @ 100 kHz), while maintaining the same package footprint and capacitance value.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0G151R is a direct functional substitute for the 2SLG150M. Both components are ROHS3 compliant and maintain identical operating temperature ranges and thermal lifetime ratings. The Panasonic part carries active product status, ensuring long-term availability and supply chain stability compared to the obsolete Rubycon component.

The EEF-CX0G151R provides superior electrical performance with a higher voltage rating (4 V versus 2 V), which offers increased design margin in low-voltage applications. The higher ripple current capability (5.1 A versus 2.7 A) supports applications with greater AC current demands. The increase in seated height from 1.10 mm to 1.90 mm must be verified against PCB layout constraints and clearance requirements for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0G151R replace the 2SLG150M in all applications?

A: The EEF-CX0G151R is electrically compatible as a substitute. The higher voltage rating (4 V) and lower ESR (15 mOhm) are advantageous for most applications. However, the increased seated height (1.90 mm versus 1.10 mm) must be verified against PCB layout and component clearance requirements.

Q: What is the significance of the voltage rating difference?

A: The 2SLG150M is rated for 2 V, while the EEF-CX0G151R is rated for 4 V. In applications operating at or below 2 V, the higher voltage rating of the substitute provides additional design margin and does not negatively impact performance.

Q: Are there any compliance differences between these parts?

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

Q: What does the height difference mean for PCB design?

A: The EEF-CX0G151R has a maximum seated height of 1.90 mm compared to the 2SLG150M at 1.10 mm. This 0.80 mm increase must be accommodated in PCB layout, particularly in applications with tight vertical clearance constraints or automated assembly height restrictions.

Q: Why is the 2SLG150M listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Rubycon. The EEF-CX0G151R from Panasonic, with active product status, provides a supported alternative for new designs and production continuity.
