ATF16V8B-15JC Equivalent & Substitute Parts

Part Overview

The ATF16V8B-15JC is a 16V8 Programmable Logic Device (PLD) IC featuring 8 macrocells with 15 ns propagation delay, housed in a 20-PLCC surface mount package. This component is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ATF16V8B-15JC is determined by the following critical parameters:

Direct Equivalents (Same Macrocell Count & Package):

• Programmable Type: EE PLD
• Number of Macrocells: 8
• Voltage - Input: 5V
• Speed: 15 ns
• Package / Case: 20-LCC (J-Lead)
• Supplier Device Package: 20-PLCC (9x9)

Functional Upgrades (Enhanced Macrocell Count):

• Programmable Type: EE PLD
• Voltage - Input: 5V
• Speed: 15 ns
• Product Status: Active

The ATF16V8B-15JU qualifies as a direct equivalent with identical electrical and mechanical specifications but active product status and improved compliance. The ATF22V10C-15JU functions as a substitute with increased macrocell capacity (10 vs. 8), different package footprint (28-PLCC vs. 20-PLCC), and active availability.

Parameter Comparison

Engineering Selection Recommendations

ATF16V8B-15JU is the primary substitute for direct replacement applications. This part maintains identical electrical specifications (8 macrocells, 15 ns speed, 5V input) and mechanical compatibility (20-PLCC package) while offering active product status, ROHS3 compliance, and verified programmability. The increased MSL rating (3 vs. 2) reflects current manufacturing standards.

ATF22V10C-15JU serves as a functional upgrade path for designs requiring additional logic capacity. With 10 macrocells versus 8, this part accommodates more complex programmable logic functions while maintaining 15 ns speed and 5V operation. The larger 28-PLCC package requires PCB layout modification. This option is suitable for new designs or redesigns where board space permits the larger footprint.

Both substitute parts are manufactured by Microchip Technology, carry ROHS3 compliance, and maintain EAR99 export classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can ATF16V8B-15JU be used as a direct drop-in replacement for ATF16V8B-15JC?

A: Yes. The ATF16V8B-15JU maintains identical electrical parameters (8 macrocells, 15 ns propagation delay, 5V input) and mechanical specifications (20-PLCC package, 20-LCC J-Lead case). No circuit modifications are required.

Q: What is the primary difference between ATF16V8B-15JU and ATF22V10C-15JU?

A: The ATF22V10C-15JU provides 10 macrocells compared to 8 in the ATF16V8B-15JU, enabling more complex logic implementations. The package footprint increases from 20-PLCC (9x9) to 28-PLCC (11.51x11.51), requiring PCB redesign. Both maintain 15 ns speed and 5V operation.

Q: Are there package compatibility considerations when substituting with ATF22V10C-15JU?

A: Yes. The ATF22V10C-15JU uses a 28-PLCC package versus the 20-PLCC of the original part. PCB layout modification is necessary to accommodate the larger footprint and increased pin count. Existing socket designs are not compatible.

Q: What compliance improvements are provided by the substitute parts?

A: Both ATF16V8B-15JU and ATF22V10C-15JU achieve ROHS3 compliance, whereas the original ATF16V8B-15JC is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

Q: How do the moisture sensitivity levels differ?

A: The ATF16V8B-15JC and ATF22V10C-15JU both carry MSL 2 (1 Year), while the ATF16V8B-15JU carries MSL 3 (168 Hours). MSL 3 indicates more stringent moisture control requirements during storage and handling.
