Key Parameters

Substitute Part Grouping Explanation

Substitution of the ESRH151M0ER is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 150 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Type: Aluminum - Polymer (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• ESR: 15 mOhm (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or greater than 2.5 V
• Lifetime @ Temperature: May be equal to or greater than 1000 Hrs @ 105°C
• Ripple Current @ High Frequency: May be equal to or greater than 2.5 A @ 100 kHz
• Physical dimensions and height may vary within the same package classification

The EEF-CX0G151R from Panasonic Electronic Components qualifies as a direct substitute based on matching all mandatory parameters while providing enhanced performance in voltage rating, thermal lifetime, and ripple current capacity.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0G151R is a qualified substitute for the ESRH151M0ER based on the following engineering criteria:

Compliance and Regulatory Status: Both components are ROHS3 compliant. The EEF-CX0G151R carries active product status from Panasonic Electronic Components, ensuring continued availability and manufacturing support. The ESRH151M0ER is classified as obsolete, making transition to an active equivalent necessary for long-term supply chain reliability.

Electrical Performance: The substitute part maintains identical capacitance (150 µF), tolerance (±20%), and ESR (15 mOhm) specifications. The higher voltage rating (4 V versus 2.5 V) and extended thermal lifetime (2000 Hrs @ 105°C versus 1000 Hrs @ 105°C) provide enhanced performance margins without introducing incompatibility. The increased ripple current rating (5.1 A @ 100 kHz versus 2.5 A @ 100 kHz) supports higher current applications.

Physical Compatibility: Both components use identical package classification (2917 / 7343 Metric) and surface mount mounting type. The substitute part features a lower seated height (1.90mm versus 2.80mm), which is advantageous for space-constrained designs and does not create compatibility issues.

Procurement Considerations: The EEF-CX0G151R is available in Tape & Reel (TR) packaging with substantial inventory (21,633 Pcs), supporting high-volume production requirements. The ESRH151M0ER, while currently in stock (1,004 Pcs), is obsolete and subject to supply discontinuation.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0G151R directly replace the ESRH151M0ER in existing designs?

A: Yes. The EEF-CX0G151R meets all mandatory electrical and mechanical parameters for direct substitution. Identical capacitance, tolerance, ESR, package type, and mounting configuration ensure functional compatibility. The higher voltage rating and thermal lifetime provide performance enhancement without introducing design conflicts.

Q: What is the significance of the voltage rating difference (2.5 V versus 4 V)?

A: The substitute part is rated for higher voltage operation. In applications where the circuit voltage does not exceed 2.5 V, the higher rating of the substitute part presents no disadvantage and provides additional safety margin. The capacitor will operate within its specified parameters at the original design voltage.

Q: Does the lower seated height (1.90mm versus 2.80mm) affect PCB layout?

A: The lower profile of the substitute part is beneficial for space-constrained designs. It does not create compatibility issues with existing PCB layouts designed for the original part. The footprint dimensions remain identical (7.30mm x 4.30mm), ensuring pad alignment compatibility.

Q: Are there any thermal performance differences?

A: The substitute part is rated for 2000 Hrs @ 105°C compared to 1000 Hrs @ 105°C for the original part. This extended thermal lifetime indicates improved long-term reliability in high-temperature environments. Both components operate across the identical temperature range (-55°C to 105°C).

Q: What packaging options are available for the substitute part?

A: The EEF-CX0G151R is supplied in Tape & Reel (TR) packaging, standard for high-volume surface mount assembly. The original ESRH151M0ER packaging format is not specified in the provided data.

Q: Are both parts RoHS compliant?

A: Yes. Both the ESRH151M0ER and EEF-CX0G151R are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: Why is the original part classified as obsolete?

A: Product obsolescence typically results from manufacturer discontinuation decisions. The EEF-CX0G151R from Panasonic maintains active product status, ensuring continued manufacturing support, availability, and technical documentation.
