Key Parameters

Substitute Part Grouping Explanation

Substitution of the ESRE221M0EB is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Capacitance: 220 µF
• Voltage Rating: 2.5 V
• Tolerance: ±20%
• Type: Aluminum - Polymer

Mechanical Parameters (Must Match):

• Package / Case: 2917 (7343 Metric)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 105°C

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant

Substitute parts may exhibit improved performance characteristics (lower ESR, higher ripple current rating, extended lifetime) while maintaining full compatibility with the original design specifications. The EEF-SX0E221ER from Panasonic Electronic Components meets all equivalence criteria and is classified as an active product.

Parameter Comparison

Engineering Selection Recommendations

The EEF-SX0E221ER is a direct electrical and mechanical equivalent to the ESRE221M0EB. Both components satisfy identical core specifications for capacitance, voltage rating, tolerance, package geometry, and operating temperature range. The substitute part is manufactured by Panasonic Electronic Components and maintains active product status, ensuring long-term availability and supply chain continuity.

The EEF-SX0E221ER demonstrates improved performance characteristics relative to the original part: reduced ESR (9 mOhm versus 12 mOhm), doubled thermal lifetime rating (2000 Hrs versus 1000 Hrs @ 105°C), and nearly doubled ripple current capacity (6.3 A versus 3.3 A @ 100 kHz). These enhancements provide additional design margin without compromising compatibility.

Both components are ROHS3 compliant and carry identical ECCN and HTSUS classifications, confirming regulatory and trade compliance equivalence. The substitute part is available in Tape & Reel packaging, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0E221ER be used as a direct replacement for the ESRE221M0EB in existing designs?

A: Yes. The EEF-SX0E221ER is electrically and mechanically equivalent. Both components share identical capacitance (220 µF), voltage rating (2.5 V), tolerance (±20%), package (2917 / 7343 Metric), and operating temperature range (-55°C ~ 105°C). No circuit modifications are required.

Q: What are the physical differences between these components?

A: The primary physical difference is seated height. The ESRE221M0EB has a maximum seated height of 0.161" (4.10 mm), while the EEF-SX0E221ER measures 0.079" (2.00 mm). Both components occupy identical footprint dimensions (0.287" L x 0.169" W / 7.30 mm x 4.30 mm) and are compatible with the same PCB land pattern.

Q: Why does the substitute part have lower ESR and higher ripple current rating?

A: These are performance improvements inherent to the substitute design. Lower ESR (9 mOhm versus 12 mOhm) and higher ripple current capacity (6.3 A versus 3.3 A @ 100 kHz) reflect advances in polymer capacitor technology and manufacturing processes. These improvements provide additional operational margin without affecting compatibility.

Q: Are there any compliance or certification differences?

A: No. Both components are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications. Regulatory and trade compliance are equivalent.

Q: What is the significance of the product status difference?

A: The ESRE221M0EB is classified as obsolete, indicating discontinued manufacturing and limited availability. The EEF-SX0E221ER is active, ensuring reliable long-term supply and continued manufacturer support. For new designs or production continuity, the active substitute is the appropriate selection.

Q: Does the difference in packaging format affect compatibility?

A: No. The ESRE221M0EB is supplied in standard packaging, while the EEF-SX0E221ER is supplied in Tape & Reel (TR) format. Both are surface mount components with identical land patterns and mounting procedures. Tape & Reel packaging is standard for automated assembly processes and does not affect electrical or mechanical compatibility.

Q: What is the thermal lifetime rating difference?

A: The ESRE221M0EB is rated for 1000 hours at 105°C, while the EEF-SX0E221ER is rated for 2000 hours at the same temperature. This extended lifetime provides additional design margin for applications requiring extended operational life at elevated temperatures.
