Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ATF22LV10C-15PI is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the 22V10 series
• Macrocell Count: Identical at 10 macrocells
• Package Configuration: Identical 24-DIP (0.300", 7.62mm) through-hole mounting
• Input Voltage: Both operate at 3.3V
• Programmable Type: Both are EE PLD (Electrically Erasable Programmable Logic Device)
• Speed Consideration: The substitute part may have equal or faster propagation delay (lower nanosecond value)

The ATF22LV10C-10PU qualifies as a direct substitute because it maintains all core electrical and mechanical parameters while offering improved speed performance (10 ns versus 15 ns).

Parameter Comparison

Engineering Selection Recommendations

The ATF22LV10C-10PU is a qualified substitute for the ATF22LV10C-15PI based on the following criteria:

Electrical Compatibility: Both devices share identical macrocell architecture, input voltage specification, and programmable logic configuration. The substitute operates at 10 ns propagation delay, which is faster than the original 15 ns specification, ensuring timing compatibility in applications designed for the original part.

Mechanical Compatibility: Pin-for-pin compatibility is maintained through identical 24-DIP packaging and through-hole mounting configuration, enabling direct socket replacement without PCB modification.

Product Status and Compliance: The substitute part is classified as Active, providing long-term availability and supply chain stability. The ATF22LV10C-10PU meets ROHS3 compliance requirements, whereas the original part is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Inventory Availability: The substitute part maintains higher stock levels (1550 Pcs) compared to the original part (835 Pcs), supporting procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can the ATF22LV10C-10PU directly replace the ATF22LV10C-15PI in existing designs?

A: Yes. The substitute maintains identical macrocell count, input voltage, package configuration, and through-hole mounting. The faster 10 ns speed specification is backward-compatible with designs specified for 15 ns operation.

Q: What is the significance of the speed difference between 15 ns and 10 ns?

A: Speed refers to propagation delay through the programmable logic device. The 10 ns specification of the substitute part is faster, meaning logic transitions occur in less time. This improvement does not create compatibility issues in applications designed for the slower 15 ns part.

Q: Are there any compliance differences between these parts?

A: The substitute part (ATF22LV10C-10PU) is ROHS3 compliant, while the original part (ATF22LV10C-15PI) is RoHS non-compliant. Both maintain REACH Unaffected status. For applications requiring RoHS compliance, the substitute is the appropriate selection.

Q: Is the 24-DIP package identical between both parts?

A: Yes. Both parts use 24-DIP (0.300", 7.62mm) packaging with through-hole mounting. No PCB layout modifications are required for substitution.

Q: What is the difference between the -15PI and -10PU suffixes?

A: The numeric portion indicates propagation delay (15 ns versus 10 ns). The letter suffix indicates packaging format: PI denotes PDIP in tube packaging, while PU denotes PDIP in tube packaging. Both are compatible with standard DIP sockets.
