Engineering Selection Recommendations

Primary Selection Criteria:

The 227SML025MD8 and ATB227M025 are electrically and mechanically interchangeable for applications requiring 220 µF capacitance at 25 V in surface mount radial can configuration. Both components maintain Active product status and full regulatory compliance under ROHS3 and REACH standards.

Selection Based on Application Requirements:

The ATB227M025 substitute part is appropriate for applications where one or more of the following conditions apply:

• Extended operational lifetime is required beyond 2000 hours
• Operating temperatures exceed 85°C
• Higher ripple current handling capability is necessary
• Lower equivalent series resistance is beneficial for signal integrity
• Wider temperature operating range (-55°C to 105°C) is required

The 227SML025MD8 main part remains suitable for general purpose applications operating within the specified temperature range of -40°C to 85°C with standard ripple current requirements.

Both parts are manufactured by the same supplier, ensuring consistent quality and reliability standards. PCB layout modifications are minimal due to compatible physical dimensions and surface mount land sizes.

Frequently Asked Questions (FAQ)

Q: Are the 227SML025MD8 and ATB227M025 pin-compatible?

A: Yes. Both components are surface mount radial can packages with identical physical diameter (0.315" / 8.00 mm) and compatible height dimensions. Surface mount land sizes are compatible for standard PCB assembly processes.

Q: Can the ATB227M025 be used as a direct replacement for the 227SML025MD8?

A: Yes. The substitute part maintains identical electrical specifications for capacitance (220 µF), voltage rating (25 V), and tolerance (±20%). Both components are polar aluminum electrolytic capacitors with identical package classification and mounting type.

Q: What are the performance differences between these two parts?

A: The ATB227M025 offers improved electrical performance with lower ESR (960 mOhm versus 1.206 Ohm at 120 Hz), higher ripple current ratings (420 mA at 120 Hz versus 230 mA), and extended operational lifetime (5000 hours at 105°C versus 2000 hours at 85°C). The substitute part also supports a wider operating temperature range (-55°C to 105°C versus -40°C to 85°C).

Q: Are both parts RoHS compliant?

A: Yes. Both the 227SML025MD8 and ATB227M025 are ROHS3 Compliant with MSL rating of 1 (Unlimited moisture sensitivity level). Both parts are REACH Unaffected.

Q: What is the inventory status for these parts?

A: The 227SML025MD8 has 834 pieces in stock. The ATB227M025 substitute has 32733 pieces in stock.

Q: Do these parts require different PCB layout considerations?

A: No significant layout changes are required. Both components use compatible surface mount land sizes (227SML025MD8: 0.327" L x 0.327" W; ATB227M025: 0.346" L x 0.335" W). Standard surface mount assembly processes apply to both parts.

Q: Which part should be selected for new designs?

A: Component selection depends on application-specific requirements. For applications requiring extended lifetime, elevated temperature operation, or higher ripple current handling, the ATB227M025 is the appropriate selection. For standard general purpose applications within the specified operating parameters, either part is suitable.
