Key Parameters

Substitute Part Grouping Explanation

Substitution of the SP723ABT is determined by strict alignment of the following critical parameters:

• Manufacturer: Littelfuse Inc.
• Package Type: 8-SOIC (0.154", 3.90mm Width)
• Number of Circuits: 6
• Technology: Mixed Technology
• Mounting Type: Surface Mount
• Applications: General Purpose
• Moisture Sensitivity Level: 1 (Unlimited)

The SP723ABTG qualifies as a direct substitute based on identical alignment across all these parameters. The primary distinction between the main part and substitute is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The SP723ABTG is the direct substitute for the obsolete SP723ABT. Selection of SP723ABTG is supported by:

• Identical electrical and mechanical specifications across all functional parameters
• Active product status ensuring ongoing availability and manufacturing support
• ROHS3 compliance, providing regulatory advantage over the non-compliant SP723ABT
• Availability in multiple packaging formats (Cut Tape and Digi-Reel®), facilitating procurement flexibility
• Equivalent ECCN and HTSUS classifications, maintaining consistent export and tariff treatment

Frequently Asked Questions (FAQ)

Q: Can SP723ABTG directly replace SP723ABT in existing designs?

A: Yes. SP723ABTG is a direct substitute with identical package, circuit count, technology, and functional specifications. No design modifications are required.

Q: What is the primary reason to transition from SP723ABT to SP723ABTG?

A: SP723ABT is obsolete. SP723ABTG is an active product from the same manufacturer with identical specifications, ensuring continued component availability and manufacturing support.

Q: Are there compliance differences between these parts?

A: Yes. SP723ABTG is ROHS3 compliant, while SP723ABT is RoHS non-compliant. This distinction may be relevant for applications subject to RoHS regulations.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 8-SOIC package with 0.154" width and 3.90mm width specification. PCB footprints are identical.

Q: What packaging options are available for SP723ABTG?

A: SP723ABTG is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for different procurement and assembly workflows.

Q: Is the moisture sensitivity level the same?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
