Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATF16V8BQL-15PC is determined by strict equivalence across the following critical parameters: identical series designation (16V8), matching macrocell count (8), equivalent speed rating (15 ns), identical input voltage specification (5V), and compatible package format (20-DIP through-hole). The ATF16V8BQL-15PU satisfies all substitution criteria as a direct functional equivalent within the same product family, differing only in packaging configuration (tube versus tray) and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The ATF16V8BQL-15PU is the direct functional substitute for the obsolete ATF16V8BQL-15PC. Both components share identical electrical specifications, macrocell architecture, speed performance, and physical package dimensions. The primary distinction is product lifecycle status: the ATF16V8BQL-15PU maintains active production status with verified programmability certification and ROHS3 compliance, whereas the ATF16V8BQL-15PC is obsolete and RoHS non-compliant. For new designs or production continuity, the ATF16V8BQL-15PU is the appropriate selection. Both parts carry REACH Unaffected status and EAR99 export classification. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both variants.

Frequently Asked Questions (FAQ)

Q: Can ATF16V8BQL-15PU directly replace ATF16V8BQL-15PC in existing designs? A: Yes. Both parts are electrically and mechanically identical. The ATF16V8BQL-15PU operates at the same 5V input voltage, provides 15 nanosecond speed performance, and uses the identical 20-DIP through-hole package. No circuit modifications are required.

Q: What is the difference between the -15PC and -15PU suffix designations? A: The suffix indicates packaging configuration. The -15PC variant uses tray packaging, while -15PU uses tube packaging. Electrical and functional specifications remain identical.

Q: Why is the ATF16V8BQL-15PC classified as obsolete? A: Product obsolescence reflects Microchip Technology's lifecycle management. The ATF16V8BQL-15PU remains in active production and is the recommended alternative for ongoing applications.

Q: Are there RoHS compliance differences between these parts? A: Yes. The ATF16V8BQL-15PC is RoHS non-compliant, while the ATF16V8BQL-15PU is ROHS3 compliant. For applications requiring RoHS certification, the ATF16V8BQL-15PU is mandatory.

Q: Do both parts support the same programming specifications? A: Yes. Both are EE PLD (Electrically Erasable Programmable Logic Device) types with 8 macrocells. The ATF16V8BQL-15PU carries verified programmability certification from DiGi-Electronics.

Q: Is the 20-DIP package footprint identical for both parts? A: Yes. Both use 20-DIP (0.300", 7.62mm) through-hole packages with identical pin configurations and PCB mounting requirements.
