Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SP720AB is determined by strict alignment with the following critical parameters:

• Manufacturer: Littelfuse Inc.
• Category: Transient Voltage Suppressors (TVS)
• Technology: Mixed Technology
• Number of Circuits: 14
• Mounting Type: Surface Mount
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Applications: General Purpose
• Moisture Sensitivity Level: 1 (Unlimited)

The SP720ABG qualifies as a direct substitute based on complete alignment across all specified parameters. The primary distinction is product status and compliance certification, with SP720ABG being an active product with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The SP720ABG is the direct equivalent for the obsolete SP720AB. Selection of SP720ABG is supported by:

• Identical electrical and mechanical specifications across all functional parameters
• Active product status with ongoing manufacturer support
• ROHS3 compliance, meeting current regulatory requirements
• REACH Unaffected status, confirming environmental compliance
• Tube packaging format for standard procurement workflows

For applications currently using SP720AB, transition to SP720ABG provides functional continuity with improved compliance posture and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can SP720ABG be used as a direct replacement for SP720AB in existing designs?

A: Yes. SP720ABG is functionally equivalent to SP720AB across all specified electrical and mechanical parameters, including circuit count, package type, and mounting configuration. Both devices are 16-SOIC surface mount TVS components with 14 circuits designed for general-purpose circuit protection.

Q: What is the primary difference between SP720AB and SP720ABG?

A: The primary differences are product status and compliance certifications. SP720AB is obsolete and RoHS non-compliant, while SP720ABG is an active product with ROHS3 compliance and REACH Unaffected status. Functionally, both devices are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both SP720AB and SP720ABG use the 16-SOIC package format with identical dimensions (0.154" width, 3.90mm). Pinout and mechanical compatibility are identical.

Q: Why should I transition from SP720AB to SP720ABG?

A: SP720AB is classified as obsolete, which limits long-term availability and manufacturer support. SP720ABG is an active product with current compliance certifications (ROHS3), ensuring regulatory alignment and supply chain continuity for new designs and production runs.

Q: Is SP720ABG available in different packaging formats?

A: SP720ABG is supplied in Tube packaging. Verify packaging requirements for your procurement and assembly processes.
