Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATF16V8BQL-15PI is determined by strict equivalence across the following parameters: manufacturer series (16V8), macrocell count (8), input voltage (5V), propagation delay (15 ns), mounting type (through hole), and package configuration (20-DIP). The substitute part ATF16V8BQL-15PU maintains identical electrical and mechanical specifications while differing only in packaging format (tube versus unspecified original packaging) and product status (active versus obsolete). This substitution is valid for direct replacement in existing designs and new applications.

Parameter Comparison

Engineering Selection Recommendations

The ATF16V8BQL-15PU is the direct functional equivalent of the ATF16V8BQL-15PI. Selection of the substitute part is justified by its active product status, ensuring long-term availability and supply chain continuity. The ATF16V8BQL-15PU achieves ROHS3 compliance, providing environmental and regulatory advantages over the obsolete original part. Both components share identical electrical performance characteristics, macrocell architecture, and physical package dimensions, enabling direct substitution without circuit redesign. For new designs or system refreshes, the ATF16V8BQL-15PU is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can ATF16V8BQL-15PU replace ATF16V8BQL-15PI in existing applications?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters: 8 macrocells, 5V operation, 15 ns speed, and 20-DIP package. Direct substitution is valid.

Q: What is the difference between the two part numbers?

A: The primary differences are packaging format (tube for the -15PU variant) and product status (active versus obsolete). The -15PU is the current production equivalent.

Q: Are there compliance differences between these parts?

A: Yes. The ATF16V8BQL-15PU is ROHS3 compliant, while the ATF16V8BQL-15PI is RoHS non-compliant. Both maintain REACH Unaffected status.

Q: Does the 20-DIP package dimension remain the same?

A: Yes. Both parts use the identical 20-DIP (0.300", 7.62mm) package configuration, ensuring PCB footprint compatibility.

Q: Why is the original part listed as obsolete?

A: The ATF16V8BQL-15PI has been discontinued by Microchip Technology. The ATF16V8BQL-15PU represents the active production line for this device family.
