Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 227SMH025ML10 are identified based on the following criteria:

Primary Substitution Criteria:

• Capacitance value: 220 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Physical dimensions: 0.394" diameter (10.00mm) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Polarization: Polar (exact match required)

Secondary Compatibility Factors:

• Voltage rating: Equal to or greater than 25 V
• Operating temperature range: Minimum -55°C to 105°C
• RoHS3 compliance: Required
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The identified substitute parts maintain identical capacitance, tolerance, package geometry, and mounting characteristics while offering variations in voltage rating, ESR performance, and thermal lifetime specifications.

Engineering Selection Recommendations

ATB227M035 Substitution:

The ATB227M035 is a direct mechanical and electrical substitute for the 227SMH025ML10 with the following distinctions:

• Voltage rating increased from 25 V to 35 V, providing additional voltage margin in circuit applications
• ESR reduced from 1.2057 Ohm to 840 mOhm, resulting in lower impedance and improved ripple current handling
• Thermal lifetime extended from 1000 hours to 5000 hours at 105°C, indicating superior long-term reliability
• Physical dimensions remain compatible with identical 10.00mm diameter and similar height (10.50mm vs 10.60mm)
• Surface mount land size differs slightly (10.80mm x 10.50mm vs 10.30mm x 10.30mm), requiring PCB layout verification
• Both parts maintain ROHS3 compliance and MSL 1 rating
• Both manufactured by Cornell Dubilier / Illinois Capacitor, ensuring consistent quality standards

MAL214097601E3 Substitution:

The MAL214097601E3 is a direct mechanical and electrical substitute for the 227SMH025ML10 with the following distinctions:

• Voltage rating remains at 25 V, matching the original specification
• Thermal lifetime extended from 1000 hours to 1500 hours at elevated temperature (125°C vs 105°C), indicating improved thermal performance
• Operating temperature range extended to -55°C to 125°C, providing wider temperature operation capability
• Physical dimensions remain compatible with identical 10.00mm diameter and similar height (10.50mm vs 10.60mm)
• Surface mount land size differs slightly (10.50mm x 10.50mm vs 10.30mm x 10.30mm), requiring PCB layout verification
• AEC-Q200 automotive qualification rating included, suitable for automotive applications
• Manufactured by Vishay Beyschlag/Draloric/BC Components, a different manufacturer with established quality standards

Frequently Asked Questions (FAQ)

Q: Can ATB227M035 be used as a direct replacement for 227SMH025ML10?

A: ATB227M035 is mechanically and electrically compatible as a substitute. The 35 V rating provides higher voltage margin than the original 25 V specification. Surface mount land size differs slightly (10.80mm x 10.50mm vs 10.30mm x 10.30mm), requiring PCB layout verification before implementation.

Q: What is the primary advantage of using MAL214097601E3 over the original 227SMH025ML10?

A: MAL214097601E3 offers extended thermal lifetime (1500 hours at 125°C vs 1000 hours at 105°C) and wider operating temperature range (-55°C to 125°C vs -55°C to 105°C). This part includes AEC-Q200 automotive qualification, making it suitable for automotive applications.

Q: Are there PCB layout considerations when substituting these parts?

A: Yes. While all three parts share the same 10.00mm diameter, surface mount land sizes differ. The original 227SMH025ML10 specifies 10.30mm x 10.30mm, ATB227M035 specifies 10.80mm x 10.50mm, and MAL214097601E3 specifies 10.50mm x 10.50mm. PCB layout must accommodate the substitute part's land size requirements.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. Both ATB227M035 and MAL214097601E3 are ROHS3 compliant, matching the original 227SMH025ML10 specification.

Q: What is the difference in ESR performance between these parts?

A: The original 227SMH025ML10 has ESR of 1.2057 Ohm at 120Hz. ATB227M035 reduces this to 840 mOhm at 120Hz, providing lower impedance. MAL214097601E3 does not specify ESR in the provided data.

Q: Can these parts be used interchangeably in all applications?

A: Mechanical and electrical compatibility is established for all three parts based on capacitance, tolerance, package type, and mounting specifications. Application-specific requirements such as voltage margin, thermal lifetime, temperature range, and automotive qualification must be evaluated for each use case.
