Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 229LBA025M2EE are qualified based on the following critical parameters that must match or exceed the main part specifications:

Mandatory Matching Parameters:

• Capacitance: 22000 µF (exact match)
• Voltage Rating: 25 V (exact match)
• Tolerance: ±20% (exact match)
• Package Type: Radial, Can - Snap-In (exact match)
• Lead Spacing: 0.394" (10.00 mm) (exact match)
• Physical Dimensions: 1.378" Dia × 1.457" Height (exact match)
• Mounting Type: Through Hole (exact match)
• Polarization: Polar (exact match)

Allowable Variations:

• Operating Temperature Range: Substitute may extend upper limit beyond 85°C
• Lifetime @ Temperature: Substitute may exceed or differ from 2000 Hrs @ 85°C specification
• Ripple Current Ratings: Substitute specifications may vary
• ESR (Equivalent Series Resistance): Substitute may differ when not specified in main part

The identified substitutes 381LX223M025A032 and B41252B5229M meet all mandatory matching parameters and are therefore electrically and mechanically compatible with the 229LBA025M2EE in through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—229LBA025M2EE, 381LX223M025A032, and B41252B5229M—are active production components with full ROHS3 compliance and REACH unaffected status, making them suitable for modern electronic applications subject to environmental regulations.

229LBA025M2EE (Main Part):

• Specified for -40°C to 85°C operating range with 2000 hours lifetime at 85°C
• ESR of 33.91 mOhm @ 120 Hz provides defined electrical performance
• Ripple current capacity: 5.73 A @ 120 Hz, 7.1625 A @ 10 kHz
• Appropriate for applications operating within standard industrial temperature ranges

381LX223M025A032 (Substitute):

• Extended operating range to 105°C with improved lifetime rating of 3000 hours @ 105°C
• Lower ripple current specifications: 4.3 A @ 120 Hz, 4.9 A @ 20 kHz
• Suitable for applications requiring extended temperature performance
• Same physical footprint and electrical ratings as main part

B41252B5229M (Substitute):

• Extended operating range to 105°C with 2000 hours lifetime @ 105°C
• Ripple current @ 120 Hz: 4.28 A
• Manufactured by EPCOS - TDK Electronics, a major capacitor supplier
• Suitable for applications requiring elevated temperature operation
• Same physical footprint and electrical ratings as main part

Selection between these parts depends on application temperature requirements and ripple current demands within the specified operating envelope.

Frequently Asked Questions (FAQ)

Q: Can 381LX223M025A032 or B41252B5229M be used as direct replacements for 229LBA025M2EE?

A: Yes. Both substitute parts match the mandatory electrical and mechanical specifications: 22000 µF capacitance, 25 V voltage rating, ±20% tolerance, and identical physical dimensions (1.378" diameter, 1.457" height, 0.394" lead spacing). All three parts use radial, can-style snap-in packaging with through-hole mounting.

Q: What are the key differences between the substitute parts?

A: The primary differences are manufacturer, series designation, and thermal performance. The 381LX223M025A032 offers 3000 hours lifetime at 105°C, while the B41252B5229M provides 2000 hours at 105°C. Both extend the upper operating temperature to 105°C compared to the main part's 85°C limit. Ripple current ratings differ slightly between parts.

Q: Are there any compatibility concerns with PCB layout?

A: No. All three parts share identical lead spacing (0.394" / 10.00 mm) and physical dimensions, ensuring direct compatibility with existing PCB designs without layout modifications.

Q: Do all parts meet current regulatory requirements?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: Which substitute should be selected for high-temperature applications?

A: Both 381LX223M025A032 and B41252B5229M support operation to 105°C. Selection between them depends on ripple current requirements and specific application thermal cycling conditions.

Q: Are moisture sensitivity considerations different between parts?

A: The 229LBA025M2EE and 381LX223M025A032 are rated MSL 1 (Unlimited). The B41252B5229M lists MSL as Not Applicable. All three parts are suitable for standard storage and handling conditions without special moisture control requirements.
