Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SP720AP are identified based on the following critical parameters that determine functional and mechanical compatibility:

• Package / Case: 16-DIP (identical form factor and pin count)
• Mounting Type: Through Hole (identical assembly method)
• Number of Circuits: 14 (identical circuit configuration)
• Technology: Mixed Technology (identical internal architecture)
• Applications: General Purpose (identical functional scope)
• Manufacturer: Littelfuse Inc. (same manufacturer ensures design continuity)

The SP720AP has one direct substitute part: SP720APP. This substitute maintains identical electrical and mechanical specifications while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SP720AP is obsolete and no longer in active production. The SP720APP is the direct substitute part from Littelfuse Inc., maintaining identical electrical and mechanical specifications while offering active product status.

Key advantages of SP720APP over SP720AP:

• Active product status ensures continued availability and manufacturer support
• ROHS3 compliance meets current environmental and regulatory requirements
• REACH Unaffected status confirms compliance with chemical substance regulations
• Tube packaging provides standard component handling and storage

Both parts share identical package geometry (16-DIP), circuit configuration (14 circuits), and mounting methodology (through-hole), ensuring direct compatibility in existing designs without PCB modifications.

Frequently Asked Questions (FAQ)

Q: Can SP720APP be used as a direct replacement for SP720AP?

A: Yes. SP720APP is a direct substitute for SP720AP. Both components feature identical 16-DIP package geometry, 14-circuit configuration, mixed technology architecture, and through-hole mounting. No design modifications are required.

Q: What is the primary reason to transition from SP720AP to SP720APP?

A: SP720AP is obsolete and no longer manufactured. SP720APP is the active equivalent part from Littelfuse Inc., ensuring continued component availability and manufacturer support for new designs and production runs.

Q: Are there compliance differences between SP720AP and SP720APP?

A: Yes. SP720APP is ROHS3 compliant and REACH Unaffected, while SP720AP is RoHS non-compliant. For applications requiring environmental compliance certification, SP720APP is the appropriate selection.

Q: Do SP720AP and SP720APP have identical pinouts?

A: Yes. Both parts use the 16-PDIP package format with identical pin assignments, enabling direct socket compatibility without rework.

Q: What packaging formats are available for SP720APP?

A: SP720APP is supplied in Tube packaging, which is the standard format for through-hole DIP components.
