Key Parameters

Substitute Part Grouping Explanation

Substitution of the ESRH151M0EB is based on the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Capacitance: 150 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• ESR: 15 mOhm (exact match required for ripple current performance)
• Operating Temperature Range: -55°C ~ 105°C (minimum requirement)
• Voltage - Rated: Equal to or greater than 2.5 V (uprating permitted)

The EEF-CX0G151R from Panasonic Electronic Components satisfies all substitution criteria with identical capacitance, tolerance, ESR, package dimensions, and mounting type. The substitute part features a higher voltage rating (4 V) and extended lifetime (2000 Hrs @ 105°C), both providing enhanced performance margins without compromising circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0G151R is recommended as the direct substitute for the obsolete ESRH151M0EB. Both components are ROHS3 compliant and suitable for applications requiring general-purpose aluminum polymer capacitor functionality. The substitute part is actively manufactured and maintained by Panasonic Electronic Components, ensuring long-term availability and supply chain stability.

The Panasonic EEF-CX0G151R offers improved performance characteristics through higher voltage rating and extended thermal lifetime, providing additional design margin without introducing functional or physical incompatibility. The reduced maximum seated height (0.075" versus 0.110") indicates improved integration density and represents a beneficial design enhancement.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0G151R be used as a direct replacement for the ESRH151M0EB? A: Yes. Both components share identical capacitance, tolerance, ESR, footprint, and mechanical package specifications, enabling direct PCB-level substitution without design modification.

Q: Does the higher voltage rating of the EEF-CX0G151R affect circuit compatibility? A: No. Higher voltage rating does not affect compatibility. Capacitors rated for higher voltages operate correctly at lower voltages. The 4 V rating of the substitute part accommodates the 2.5 V design requirement with improved safety margin.

Q: Are there physical placement concerns due to the different heights? A: No. The EEF-CX0G151R has a lower maximum seated height (0.075" versus 0.110"), which provides additional clearance. PCB layout accommodation for the original part will accommodate the substitute without constraint.

Q: What is the difference in ripple current capability? A: The EEF-CX0G151R supports 5.1 A @ 100 kHz compared to 2.5 A for the ESRH151M0EB. This represents enhanced thermal performance and increased headroom for ripple current applications.

Q: Are RoHS compliance requirements met by both parts? A: Yes. Both the ESRH151M0EB and EEF-CX0G151R are ROHS3 compliant, satisfying regulatory requirements for hazardous substance restrictions.

Q: Why is the ESRH151M0EB classified as obsolete? A: Obsolescence status indicates that the component is no longer manufactured by Cornell Dubilier Electronics and is no longer recommended for new designs. The EEF-CX0G151R from Panasonic is an actively supported alternative for ongoing production and new development.
