Substitute Part Grouping Explanation

The ATF16V8C-7PU qualifies as a direct substitute for the ATF16V8C-7PC based on identical core electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Identical series designation (16V8)
• Matching macrocell count (8 macrocells)
• Identical programmable type (EE PLD)
• Matching speed specification (7.5 ns)
• Identical input voltage requirement (5V)
• Identical package and pinout (20-PDIP)
• Identical mounting type (Through Hole)

The primary distinction between these parts is packaging format and product status, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ATF16V8C-7PU is the direct functional equivalent for the obsolete ATF16V8C-7PC. Selection of the ATF16V8C-7PU is appropriate for:

• Replacement in existing designs currently using ATF16V8C-7PC
• New designs requiring 16V8 PLD functionality with 8 macrocells and 7.5 ns performance
• Applications requiring active product status and ongoing manufacturer support
• Systems requiring ROHS3 compliance

The ATF16V8C-7PU maintains identical electrical performance, pinout, and package dimensions, enabling direct substitution without circuit redesign. The transition from obsolete to active product status ensures continued availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can ATF16V8C-7PU directly replace ATF16V8C-7PC in existing circuits?

A: Yes. Both parts share identical electrical specifications, pinout, and package dimensions (20-PDIP). No circuit modifications are required for substitution.

Q: What is the primary difference between these two parts?
