Equivalent & Substitute Parts for 2SXB150M

Part Overview

The 2SXB150M is a 150 µF, 2 V aluminum polymer capacitor manufactured by Rubycon in the 2917 (7343 Metric) surface mount package. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing production and maintenance applications. The part is designed for general-purpose applications requiring low equivalent series resistance and stable performance across extended temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SXB150M is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 150 µF (exact match required)
• Package / Case: 2917 (7343 Metric) (physical and electrical compatibility)
• Mounting Type: Surface Mount (assembly compatibility)
• Type: Aluminum Polymer (electrical characteristics and performance profile)

Allowable Parameter Variations:

• Voltage Rating: The substitute may exceed the original rating (2 V original; 4 V substitute acceptable for higher voltage margin)
• ESR: Substitute values within the same performance class are acceptable
• Ripple Current: Higher ratings provide additional design margin
• Product Status: Active status preferred over obsolete for long-term availability

The EEF-CX0G151R from Panasonic meets all mandatory matching criteria while providing enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0G151R is a direct functional substitute for the 2SXB150M. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute part offers the following advantages:

• Active product status ensures continued availability and supply chain stability
• Higher voltage rating (4 V vs. 2 V) provides increased design margin for voltage transients
• Enhanced ripple current capability (5.1 A vs. 3 A @ 100 kHz) supports higher current applications
• Identical physical footprint and mounting characteristics enable direct PCB replacement
• Equivalent thermal performance (2000 Hrs @ 105°C) maintains reliability specifications

The 2 mOhm increase in ESR (13 mOhm to 15 mOhm) remains within acceptable performance tolerances for general-purpose applications and does not compromise circuit functionality.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0G151R be used as a direct replacement for the 2SXB150M on existing PCBs?

A: Yes. Both components share identical package dimensions (2917 / 7343 Metric), surface mount land patterns, and electrical characteristics within the specified tolerance ranges. No PCB modifications are required.

Q: Why is the substitute part rated at 4 V instead of 2 V?

A: Higher voltage ratings provide additional design margin and protection against voltage transients. A 4 V rated capacitor is fully compatible with 2 V circuit applications and offers improved reliability.

Q: Are there any thermal performance differences between these parts?

A: Both components specify 2000 hours lifetime at 105°C and identical operating temperature ranges (-55°C to 105°C). Thermal performance is equivalent.

Q: What is the significance of the ESR difference (13 mOhm vs. 15 mOhm)?

A: The 2 mOhm difference represents a 15% increase in equivalent series resistance. For general-purpose applications, this variation remains within acceptable performance parameters and does not affect circuit functionality.

Q: Is the substitute part available in the same packaging format?

A: The EEF-CX0G151R is supplied in Tape & Reel (TR) format, which is standard for high-volume production. The 2SXB150M packaging format was not specified in the original documentation.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both the 2SXB150M and EEF-CX0G151R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
