ATF16V8C-5JC Equivalent & Substitute Parts

Part Overview

The ATF16V8C-5JC is a 16V8 Programmable Logic Device (PLD) IC featuring 8 macrocells with 5 nanosecond propagation delay, housed in a 20-PLCC surface mount package. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement. The ATF16V8C series remains functionally relevant for legacy system maintenance and reproduction applications where pin-compatible alternatives are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ATF16V8C-5JC is determined by strict equivalence across the following critical parameters:

• Macrocell count: 8 macrocells (functional logic capacity)
• Input voltage: 5V (electrical compatibility)
• Propagation delay: 5 ns (timing specification)
• Package type: 20-PLCC (9x9) with J-Lead configuration (physical and electrical pinout compatibility)
• Programmable type: EE PLD (electrically erasable programmable logic device)
• Mounting configuration: Surface mount (PCB assembly compatibility)

The ATF16V8C-5JX qualifies as a direct substitute based on identical alignment across all critical parameters. The primary distinction is product status and compliance certification, not functional or physical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ATF16V8C-5JX is the direct functional equivalent for applications currently using the ATF16V8C-5JC. Selection between these parts should be based on the following criteria:

For new designs or systems requiring regulatory compliance: The ATF16V8C-5JX is the appropriate choice, as it maintains active product status and carries ROHS3 compliance certification. This part is suitable for procurement in production quantities with standard lead times.

For legacy system maintenance or reproduction: The ATF16V8C-5JC remains available in inventory (1574 units) and provides identical electrical and physical characteristics. However, the obsolete status indicates limited future availability and no manufacturer support for new programming or technical documentation.

Both parts share identical electrical specifications, timing characteristics, and pinout configurations, ensuring direct substitution without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the ATF16V8C-5JX replace the ATF16V8C-5JC in existing designs?

A: Yes. Both parts are electrically and physically identical across all functional parameters: 8 macrocells, 5V input, 5 ns speed, and 20-PLCC package. No circuit changes are required for substitution.

Q: What is the difference between the ATF16V8C-5JC and ATF16V8C-5JX?

A: The primary differences are product status and compliance certification. The ATF16V8C-5JC is obsolete and RoHS non-compliant. The ATF16V8C-5JX is active and ROHS3 compliant. Functionally and electrically, they are equivalent.

Q: Why is the ATF16V8C-5JC classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support. This does not affect the part's functionality but signals limited future availability and no manufacturer technical support.

Q: Are there packaging differences between these parts?

A: The ATF16V8C-5JX is supplied in tube packaging, while the ATF16V8C-5JC packaging is not specified. Both use the same 20-PLCC (9x9) J-Lead surface mount package for PCB assembly.

Q: Which part should be selected for new production?

A: The ATF16V8C-5JX is recommended for new production due to active status, ROHS3 compliance, and assured long-term availability. The ATF16V8C-5JC should be reserved for legacy system support only.
