Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMF05LCFLP-7 is determined by strict equivalence across the following critical parameters:

• Electrical Characteristics: Voltage - Reverse Standoff (5V Min), Voltage - Breakdown (6V Min), Voltage - Clamping (12.5V Max), and Power - Peak Pulse (70W)
• Physical Form Factor: 6-UFDFN Exposed Pad package with Surface Mount configuration
• Functional Architecture: Unidirectional Zener TVS diode with 5 channels
• Environmental & Compliance Standards: Automotive Grade, AEC-Q101 qualification, ROHS3 compliance, and -55°C ~ 150°C operating temperature range

The substitute part DMF05LCFLPA-7 maintains identical electrical performance and package specifications. The primary difference is packaging format: the original uses Cut Tape (CT) while the substitute uses Tape & Reel (TR), and the substitute includes specified peak pulse current (5A @ 8/20µs) and capacitance data (25pF @ 1MHz).

Parameter Comparison

Engineering Selection Recommendations

The DMF05LCFLPA-7 is the direct functional equivalent to the DMF05LCFLP-7. Both components share identical electrical specifications, package geometry, and automotive-grade qualification. The substitute part is currently in Active product status, ensuring long-term availability and supply chain continuity compared to the Last Time Buy status of the original part.

The primary distinction between these parts is packaging format: Cut Tape versus Tape & Reel. This difference affects procurement and assembly logistics but does not impact electrical performance or circuit compatibility. Selection between these parts should be based on manufacturing process requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can DMF05LCFLPA-7 be used as a direct replacement for DMF05LCFLP-7 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical voltage ratings (5V reverse standoff, 6V breakdown, 12.5V clamping), power dissipation (70W peak pulse), package form factor (6-UFDFN Exposed Pad), and operating temperature range (-55°C ~ 150°C). PCB layout and schematic connections require no modification.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging provides individual component strips suitable for manual handling and small-volume assembly. Tape & Reel (TR) packaging supplies components on continuous reels optimized for automated pick-and-place assembly equipment. Both formats contain identical components; the difference is in delivery and handling method.

Q: Why is the original part marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing production. This necessitates transition to an active equivalent part to maintain design support and ensure future procurement availability. The DMF05LCFLPA-7 provides this continuity.

Q: Are there any compliance or certification differences between these parts?

A: Both parts meet automotive-grade requirements and are manufactured by Diodes Incorporated. The original part explicitly lists AEC-Q101 qualification and ROHS3 compliance. The substitute part maintains the same automotive-grade classification and manufacturing standards, ensuring equivalent reliability and regulatory compliance for automotive applications.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are electrically and mechanically identical with the same package specifications, they can be used interchangeably within the same circuit design and production run without affecting circuit performance or reliability.
