Substitute Part Grouping Explanation

Substitution of the ESRD151M0ER requires evaluation against the following critical parameters: capacitance value (150 µF), voltage rating (2.5 V minimum), package type (2917/7343 Metric), mounting method (surface mount), and electrical characteristics (ESR and ripple current rating).

The substitute part EEF-CX0G151R meets the fundamental substitution criteria based on the following allowed parameters:

Capacitance: Both parts specify 150 µF ±20%
Package / Case: Both use 2917 (7343 Metric) surface-mount package
Mounting Type: Both are surface-mount
Voltage Rating: EEF-CX0G151R is rated 4 V (exceeds 2.5 V requirement)
ESR: Both specify 15 mOhm
Operating Temperature Range: Both support -55°C to 105°C
Type: Both are aluminum-polymer capacitors
RoHS Compliance: Both are ROHS3 compliant

The EEF-CX0G151R is an active product with improved specifications in lifetime rating (2000 hours @ 105°C versus 1000 hours) and ripple current capability (5.1 A @ 100 kHz versus 3 A).

Engineering Selection Recommendations

The EEF-CX0G151R qualifies as a direct substitute for the ESRD151M0ER based on matching electrical specifications and identical mechanical package dimensions. The substitute part offers superior product status (active versus obsolete), ensuring continued availability and supply chain reliability. Both parts maintain ROHS3 compliance and equivalent operating temperature specifications.

The EEF-CX0G151R demonstrates improved performance characteristics within the scope of this substitution: extended lifetime rating (2000 hours versus 1000 hours at 105°C) and increased ripple current capability (5.1 A versus 3 A at 100 kHz). The substitute part's 4 V voltage rating provides additional design margin when replacing the 2.5 V rated ESRD151M0ER in equivalent circuit applications. The reduced seated height (0.075" versus 0.110") is compatible with surface-mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0G151R replace the ESRD151M0ER in existing designs?

A: Yes. The EEF-CX0G151R meets all critical substitution parameters: identical 150 µF capacitance, matching 2917 (7343 Metric) package footprint, equivalent 15 mOhm ESR, and compatible operating temperature range (-55°C to 105°C). The higher voltage rating (4 V) of the substitute part is suitable for applications designed for 2.5 V operation.

Q: What are the key differences between these parts?

A: The primary differences are product status (EEF-CX0G151R is active; ESRD151M0ER is obsolete), lifetime rating (2000 hours versus 1000 hours at 105°C), ripple current capability (5.1 A versus 3 A at 100 kHz), and seated height (0.075" versus 0.110"). Both parts maintain identical capacitance, voltage compatibility, ESR, and package footprint.

Q: Are there mounting or land pattern concerns?

A: No. Both parts use identical surface-mount package specifications (2917/7343 Metric) with matching 0.287" x 0.169" footprints. The EEF-CX0G151R's reduced seated height provides improved clearance for component assembly and may reduce PCB profile.

Q: Does the substitute part have equivalent RoHS compliance?

A: Yes. The EEF-CX0G151R is ROHS3 compliant, matching the ESRD151M0ER's compliance status. Both parts are suitable for applications with regulatory RoHS requirements.

Q: Should the 4 V rating of the substitute affect circuit design?

A: No. The EEF-CX0G151R's 4 V rating represents a higher-rated component suitable for 2.5 V applications. In designs where the ESRD151M0ER was specified, the EEF-CX0G151R operates at reduced stress, extending operating life and improving reliability margins.
