ESRH221M0EB Equivalent & Substitute Parts Reference

Part Overview

The ESRH221M0EB is a 220 µF, 2.5 V aluminum-polymer surface mount capacitor manufactured by Cornell Dubilier Electronics (CDE) in the 2917 (7343 Metric) package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The part delivers 12 mOhm equivalent series resistance with a 1000-hour lifetime rating at 105°C, suitable for general-purpose applications requiring compact form factors and low ESR characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ESRH221M0EB is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Capacitance value: 220 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)
• ESR: 12 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 @ 100 kHz: May be equal to or greater than 3 A
• Height - Seated: May be equal to or less than 0.161" (4.10mm)

The EEF-CX0G221XR from Panasonic Electronic Components qualifies as a direct substitute based on matching all critical parameters while exceeding allowable variation thresholds in voltage rating, thermal lifetime, and ripple current capacity.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0G221XR qualifies as a direct substitute for the obsolete ESRH221M0EB based on electrical and mechanical parameter alignment. Both components are ROHS3 compliant and maintain identical capacitance, tolerance, ESR, and package specifications.

The Panasonic substitute provides enhanced performance margins: the 4 V voltage rating exceeds the 2.5 V requirement, the 2000-hour thermal lifetime doubles the original specification, and the 5.6 A ripple current capacity at 100 kHz exceeds the 3 A baseline. The reduced height of 0.075" (1.90mm) compared to 0.161" (4.10mm) offers improved board-level design flexibility without compromising electrical performance.

The active product status of the EEF-CX0G221XR ensures ongoing availability and supply chain continuity, addressing the obsolescence constraint of the original component.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0G221XR be used as a direct replacement for the ESRH221M0EB in existing designs?

A: Yes. Both components share identical capacitance (220 µF), tolerance (±20%), ESR (12 mOhm), package (2917 / 7343 Metric), and mounting type (Surface Mount). The substitute meets or exceeds all electrical and thermal specifications of the original part.

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

A: The substitute's higher voltage rating (4 V) provides additional safety margin in applications designed for 2.5 V operation. This does not create compatibility issues; the component operates safely at lower voltages than its rated maximum.

Q: How does the thermal lifetime difference affect component selection?

A: The EEF-CX0G221XR provides 2000 hours at 105°C compared to the original 1000 hours. This extended lifetime indicates improved thermal stability and longer operational endurance under elevated temperature conditions, benefiting long-term reliability.

Q: Are there any height or form factor considerations for PCB layout?

A: The substitute component has a lower seated height (0.075" vs. 0.161"), which may improve board-level clearance and design flexibility. The identical footprint (7.30mm x 4.30mm) ensures direct PCB land pattern compatibility.

Q: Do both components meet the same compliance standards?

A: Yes. Both the ESRH221M0EB and EEF-CX0G221XR are ROHS3 compliant. The Panasonic substitute additionally carries REACH Unaffected status, providing expanded regulatory coverage for certain applications.

Q: What is the packaging format difference between the original and substitute?

A: The original ESRH221M0EB is supplied in standard packaging. The EEF-CX0G221XR is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations and does not affect component electrical or mechanical properties.
