Key Parameters

Substitute Part Grouping Explanation

Substitution of the SP0505BAHT is determined by strict equivalence across the following critical parameters:

• Unidirectional Channels: 5
• Voltage - Reverse Standoff (Typ): 5.5V (Max)
• Voltage - Clamping (Max) @ Ipp: 8.5V
• Package / Case: SOT-23-6
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 85°C (TA)

The SP0505BAHTG qualifies as a direct substitute because it maintains identical electrical specifications and physical packaging while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The SP0505BAHTG is the direct equivalent substitute for the obsolete SP0505BAHT. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility in existing circuit designs.

The SP0505BAHTG offers significant advantages for new designs and procurement:

• Active product status ensures long-term availability and manufacturing support
• ROHS3 compliance meets current environmental and regulatory requirements
• Enhanced packaging options (Cut Tape and Digi-Reel) improve supply chain flexibility
• Identical performance characteristics eliminate the need for circuit redesign or re-qualification

For applications currently using SP0505BAHT, direct replacement with SP0505BAHTG requires no circuit modifications or performance validation beyond standard component verification procedures.

Frequently Asked Questions (FAQ)

Q: Can SP0505BAHTG be used as a direct replacement for SP0505BAHT?

A: Yes. Both components are electrically and mechanically identical, with matching reverse standoff voltage (5.5V), clamping voltage (8.5V), channel configuration (5 unidirectional), and SOT-23-6 package specifications. No circuit modifications are required.

Q: What is the primary reason to transition from SP0505BAHT to SP0505BAHTG?

A: The SP0505BAHT is obsolete, while SP0505BAHTG maintains active product status. Additionally, SP0505BAHTG is ROHS3 compliant, whereas SP0505BAHT is not. These factors ensure continued availability and regulatory compliance.

Q: Are there any packaging differences between these parts?

A: SP0505BAHTG is available in Cut Tape (CT) and Digi-Reel packaging options, providing greater supply chain flexibility. The SP0505BAHT packaging specification was not detailed in available documentation.

Q: Do these components have identical operating temperature ranges?

A: Yes. Both SP0505BAHT and SP0505BAHTG operate across -40°C to 85°C (TA), ensuring equivalent thermal performance in all specified applications.

Q: Is re-qualification required when switching from SP0505BAHT to SP0505BAHTG?

A: No formal re-qualification is necessary due to complete electrical and mechanical equivalence. Standard component verification procedures are sufficient for design validation.
