Key Parameters

Substitute Part Grouping Explanation

Substitution of the EEF-UE0G221XE is determined by strict equivalence across the following parameters:

• Capacitance Value: 220 µF (exact match required)
• Voltage Rating: 4 V (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)

Substitute parts must maintain identical electrical specifications for capacitance, voltage, and tolerance. Physical package dimensions and mounting compatibility are mandatory. Variations in ESR, ripple current capability, lifetime rating, and operating temperature range are permitted within the aluminum-polymer capacitor category, provided the core electrical parameters remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes (Active Product Status)

The EEF-CX0G221R, EEF-CX0G221XR, and EEF-SX0G221ER are all active Panasonic products that meet the core electrical and mechanical requirements for direct substitution. All three are ROHS3 compliant and REACH unaffected, supporting modern regulatory requirements. The EEF-CX and EEF-SX series offer extended lifetime ratings of 2000 hours at 105°C compared to the original 1000-hour specification, providing improved reliability margins.

Alternative Substitute (Obsolete Status)

The ECASD60G227M010K00 from Murata Electronics is electrically equivalent with matching 10 mOhm ESR and 1000-hour lifetime. However, this part is also classified as obsolete. Selection of this substitute should be limited to applications requiring exact ESR matching or where Murata qualification is mandated. ROHS3 compliance and REACH unaffected status are confirmed.

Recommendation Basis

For new designs and production continuity, select from the active Panasonic substitutes. The EEF-SX0G221ER offers the lowest ESR (9 mOhm) and highest ripple current capability (6.3 A @ 100 kHz), providing superior performance characteristics. The EEF-CX0G221XR balances ESR performance (12 mOhm) with extended lifetime rating. Both maintain identical package footprint and mounting compatibility with the original EEF-UE0G221XE.

Frequently Asked Questions (FAQ)

Q: Can EEF-CX0G221R, EEF-CX0G221XR, and EEF-SX0G221ER be used interchangeably with EEF-UE0G221XE?

A: Yes. All three parts share identical capacitance (220 µF), voltage rating (4 V), tolerance (±20%), package (2917 / 7343 Metric), and mounting type (Surface Mount). Differences in ESR, ripple current, and lifetime rating do not prevent functional substitution in general-purpose applications.

Q: What is the primary difference between the Panasonic substitute options?

A: The EEF-SX0G221ER has the lowest ESR at 9 mOhm and highest ripple current at 6.3 A @ 100 kHz. The EEF-CX0G221XR offers 12 mOhm ESR with 5.6 A ripple current. The EEF-CX0G221R has 15 mOhm ESR with 5.1 A ripple current. All three provide 2000-hour lifetime at 105°C, exceeding the original 1000-hour specification.

Q: Is the Murata ECASD60G227M010K00 a suitable replacement?

A: The ECASD60G227M010K00 meets all core electrical and mechanical requirements with matching 10 mOhm ESR and 1000-hour lifetime. However, it is classified as obsolete. Use this substitute only when Murata qualification is required or when exact ESR matching is critical to circuit performance.

Q: Are there any physical dimension differences between these substitutes?

A: All substitutes use the 2917 (7343 Metric) package with identical surface mount land size (0.287" L x 0.169" W / 7.30mm x 4.30mm). Height variations exist: EEF-UE0G221XE at 0.165" (4.20mm), EEF-CX series at 0.075" (1.90mm), EEF-SX0G221ER at 0.079" (2.00mm), and ECASD60G227M010K00 at 0.110" (2.80mm). These height differences do not affect PCB footprint compatibility but may impact board-level clearance in space-constrained designs.

Q: Do all substitutes meet current regulatory compliance standards?

A: The three active Panasonic substitutes (EEF-CX0G221R, EEF-CX0G221XR, EEF-SX0G221ER) are ROHS3 compliant and REACH unaffected. The Murata ECASD60G227M010K00 is also ROHS3 compliant and REACH unaffected. The original EEF-UE0G221XE compliance status is not specified in available documentation.
