Key Parameters

Substitute Part Grouping Explanation

Substitution for the ATF16V8B-10PC is determined by strict equivalence in the following parameters:

• Series: 16V8
• Number of Macrocells: 8
• Voltage - Input: 5V
• Mounting Type: Through Hole
• Package / Case: 20-DIP (0.300", 7.62mm)
• Programmable Type: EE PLD

Speed (propagation delay) is a secondary parameter that permits substitution when the alternative part meets or exceeds performance requirements. The identified substitute parts maintain full compatibility with the electrical and mechanical specifications of the main part while offering improved or equivalent speed characteristics.

Parameter Comparison

Engineering Selection Recommendations

ATF16V8B-15PU is suitable for applications where the 15 ns speed specification meets timing requirements. This part is active in production, ROHS3 compliant, and available in higher inventory quantities (24,212 pcs), making it the preferred choice for new designs requiring RoHS compliance and long-term availability.

ATF16V8C-7PU provides superior speed performance at 7.5 ns, exceeding the original 10 ns specification. This part is active in production and ROHS3 compliant. Selection of this part is appropriate for timing-critical applications or when enhanced performance margin is required. Inventory availability is lower (1,900 pcs) compared to ATF16V8B-15PU.

Both substitute parts maintain full electrical and mechanical compatibility with the ATF16V8B-10PC while offering active product status and modern compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can ATF16V8B-15PU replace ATF16V8B-10PC in existing designs?

A: Yes. The ATF16V8B-15PU maintains identical electrical specifications (5V input, 8 macrocells, EE PLD type) and mechanical compatibility (20-DIP package, through-hole mounting). The 15 ns speed is slower than the original 10 ns specification; verify that your circuit timing requirements accommodate this difference.

Q: What is the primary advantage of ATF16V8C-7PU over ATF16V8B-15PU?

A: ATF16V8C-7PU offers faster propagation delay at 7.5 ns, compared to 15 ns for ATF16V8B-15PU. Both parts are electrically and mechanically equivalent to the ATF16V8B-10PC. Speed selection depends on circuit timing requirements.

Q: Are there package differences between these parts?

A: No. All three parts use the 20-DIP (0.300", 7.62mm) package with through-hole mounting. Physical and electrical pin compatibility is maintained across all substitute options.

Q: Why is the original ATF16V8B-10PC listed as obsolete?

A: The ATF16V8B-10PC has been discontinued by Microchip Technology. Both substitute parts (ATF16V8B-15PU and ATF16V8C-7PU) are active products, ensuring continued availability for new production and design requirements.

Q: Do the substitute parts meet current compliance standards?

A: Yes. Both ATF16V8B-15PU and ATF16V8C-7PU are ROHS3 compliant, whereas the original ATF16V8B-10PC is RoHS non-compliant. Both substitute parts are REACH Unaffected.
