• Switching frequency: 67 kHz
• Power rating: 25W
• Duty cycle: 72%
• Fault protection features: Current Limiting, Open Loop, Over Load, Over Temperature, Over Voltage
• Control features: Soft Start

Mechanical Parameters (Identical):

• Package type: 8-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Supplier device package: PG-DIP-8

Functional Parameters (Identical):

• Topology: Flyback
• Output isolation: Isolated
• Internal switch configuration: Yes
• Operating temperature range: -40°C ~ 150°C (TJ)

Parameter Comparison

Engineering Selection Recommendations

The ICE3B0565XKLA1 is the direct substitute for the obsolete ICE3B0565. Both parts share identical electrical specifications, mechanical packaging, and functional characteristics, enabling pin-for-pin replacement without circuit modification.

The ICE3B0565XKLA1 carries ROHS3 compliance certification, providing regulatory advantage for new production and updated designs. Both parts maintain MSL Level 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.

The ICE3B0565XKLA1 is classified as "Not For New Designs," indicating limited future availability. For applications requiring long-term supply assurance, evaluation of alternative offline switch topologies from current product lines is recommended as a secondary contingency measure.

Frequently Asked Questions (FAQ)

Q: Can ICE3B0565XKLA1 replace ICE3B0565 in existing designs?

A: Yes. The ICE3B0565XKLA1 is a direct substitute with identical electrical ratings (650V breakdown, 8.5V-21V supply, 67 kHz switching, 25W power), identical package (8-DIP through-hole), and identical functional features (flyback topology, soft start, comprehensive fault protection). No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance certifications. The ICE3B0565 is Obsolete, while ICE3B0565XKLA1 is Not For New Designs. The ICE3B0565XKLA1 includes ROHS3 compliance certification. All electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: Both parts use the same 8-DIP (0.300", 7.62mm) package with through-hole mounting. The ICE3B0565XKLA1 is supplied in Tube packaging, while the original ICE3B0565 packaging format is not specified. Both are compatible with standard DIP sockets and PCB layouts.

Q: What protection features are included in these parts?

A: Both the ICE3B0565 and ICE3B0565XKLA1 include current limiting, open loop protection, overload protection, over-temperature protection, and over-voltage protection. Soft start control is integrated to reduce inrush current during power-up.

Q: Are these parts suitable for new designs?

A: The ICE3B0565XKLA1 is classified as Not For New Designs, indicating limited future availability. For new designs requiring offline flyback switch functionality, evaluation of current-generation alternatives from Infineon's CoolMOS or CoolSET product families is recommended.
