Key Parameters

Substitute Part Grouping Explanation

Substitution of the ESRD151M0EB is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 150 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Type: Aluminum - Polymer (exact match required)

Allowable Variation Parameters:

• Voltage Rating: Substitute must equal or exceed 2.5 V
• ESR: Substitute must equal or be lower than 15 mOhm
• Lifetime @ Temperature: Substitute must equal or exceed 1000 Hrs @ 105°C
• Ripple Current @ 100 kHz: Substitute must equal or exceed 3 A
• Operating Temperature Range: Substitute must encompass or exceed -55°C ~ 105°C

The EEF-CX0G151R from Panasonic Electronic Components meets all mandatory matching parameters and exceeds allowable variation parameters, qualifying it as a direct substitute for the ESRD151M0EB.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0G151R is a qualified substitute for the ESRD151M0EB based on the following engineering criteria:

Electrical Compatibility: The substitute part maintains identical capacitance (150 µF), tolerance (±20%), and ESR (15 mOhm) specifications. The voltage rating of 4 V exceeds the original 2.5 V requirement, providing additional design margin. The ripple current capability of 5.1 A at 100 kHz exceeds the original 3 A specification, supporting higher current applications.

Thermal Performance: The EEF-CX0G151R provides extended lifetime of 2000 hours at 105°C compared to the original 1000 hours, improving long-term reliability in thermal stress conditions.

Physical Compatibility: Both parts utilize identical 2917 (7343 Metric) surface mount packaging with matching land sizes (0.287" L x 0.169" W / 7.30mm x 4.30mm), ensuring direct PCB layout compatibility without redesign.

Regulatory Compliance: Both the original and substitute parts are ROHS3 compliant. The EEF-CX0G151R additionally carries REACH Unaffected status, meeting extended environmental compliance requirements.

Supply Status: The EEF-CX0G151R is in active production with substantial inventory availability (21,633 pieces), ensuring reliable long-term supply compared to the obsolete ESRD151M0EB.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0G151R directly replace the ESRD151M0EB without PCB modifications?

A: Yes. Both parts share identical 2917 (7343 Metric) package dimensions and surface mount land patterns (0.287" L x 0.169" W / 7.30mm x 4.30mm). No PCB layout changes are required for physical substitution.

Q: Why does the EEF-CX0G151R have a higher voltage rating (4 V vs. 2.5 V)?

A: Higher voltage ratings in capacitor design provide increased design margin and reliability. The 4 V rating of the substitute part does not negatively impact circuit performance in applications rated for 2.5 V operation. The capacitance and ESR remain identical, ensuring equivalent electrical behavior.

Q: Are there differences in height between these two parts?

A: Yes. The ESRD151M0EB has a maximum seated height of 0.110" (2.80mm), while the EEF-CX0G151R has a maximum seated height of 0.075" (1.90mm). The substitute part is physically lower, which may provide additional PCB clearance benefits. Verify clearance in your specific application if height-constrained.

Q: What is the significance of the extended lifetime specification (2000 Hrs vs. 1000 Hrs @ 105°C)?

A: The EEF-CX0G151R provides double the rated lifetime at elevated temperature, indicating improved long-term reliability and reduced degradation rates in thermal stress conditions. This specification enhancement does not affect immediate performance but improves long-term field reliability.

Q: Are both parts RoHS compliant?

A: Yes. Both the ESRD151M0EB and EEF-CX0G151R are ROHS3 compliant. The EEF-CX0G151R additionally carries REACH Unaffected certification, meeting extended environmental and regulatory requirements.

Q: What is the difference in ripple current capability?

A: The ESRD151M0EB is rated for 3 A ripple current at 100 kHz, while the EEF-CX0G151R is rated for 5.1 A at the same frequency. The substitute part supports higher AC current stress, providing additional margin for high-frequency switching applications.

Q: Is the packaging format different between these parts?

A: The ESRD151M0EB is supplied in standard packaging, while the EEF-CX0G151R is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume surface mount assembly and does not affect component performance or compatibility.
