Key Parameters

Substitute Part Grouping Explanation

Substitution of the SP724AHT is determined by the following critical parameters:

• Package / Case: SOT-23-6 (physical and electrical compatibility requirement)
• Technology: Mixed Technology (functional equivalence)
• Number of Circuits: 4 (circuit configuration match)
• Mounting Type: Surface Mount (assembly compatibility)
• Category: Transient Voltage Suppressors (TVS) (functional classification)
• Manufacturer: Littelfuse Inc. (same manufacturer ensures design continuity)

The SP724AHTG qualifies as a direct substitute based on matching all critical parameters while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The SP724AHTG is the direct substitute for the obsolete SP724AHT. Both components share identical electrical and mechanical specifications, including package type, circuit configuration, and functional classification. The SP724AHTG offers the following advantages:

• Active product status ensures long-term availability and manufacturing support
• ROHS3 compliance meets current environmental and regulatory requirements
• REACH Unaffected status confirms compliance with chemical substance regulations
• Identical SOT-23-6 package enables direct PCB layout compatibility
• Same manufacturer (Littelfuse Inc.) maintains design continuity and performance characteristics

Frequently Asked Questions (FAQ)

Q: Can SP724AHTG be used as a direct replacement for SP724AHT?

A: Yes. The SP724AHTG is a direct substitute. Both components share identical package type (SOT-23-6), technology (Mixed Technology), circuit count (4), and functional classification (Transient Voltage Suppressors). No PCB layout modifications are required.

Q: What is the primary reason to transition from SP724AHT to SP724AHTG?

A: The SP724AHT is classified as obsolete, while SP724AHTG maintains active product status. This ensures continued availability, manufacturing support, and compliance with current regulatory standards including ROHS3 and REACH requirements.

Q: Are there any packaging differences between these parts?

A: Both components use the SOT-23-6 surface mount package. The SP724AHTG is available in Cut Tape (CT) and Digi-Reel® packaging options, providing flexibility for different procurement and assembly requirements.

Q: Do these components have identical electrical performance?

A: Both components are specified with identical technology classification (Mixed Technology), circuit configuration (4 circuits), and functional application (General Purpose Transient Voltage Suppression). Electrical performance characteristics are equivalent.

Q: What compliance certifications differ between these parts?

A: The SP724AHTG is ROHS3 compliant and REACH Unaffected, while the SP724AHT is RoHS non-compliant. Both share identical ECCN (EAR99) and HTSUS (8536.30.8000) classifications.
