ATF16V8B-15PC Equivalent & Substitute Parts

Part Overview

The ATF16V8B-15PC is a 16V8 Programmable Logic Device (PLD) IC manufactured by Microchip Technology, featuring 8 macrocells with 15 nanosecond propagation delay in a 20-pin DIP package. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement continuity. The ATF16V8B series remains functionally relevant for legacy system maintenance and new designs requiring EE PLD functionality with 5V input specifications.

Substitute Part Grouping Explanation

Substitution of the ATF16V8B-15PC is determined by strict equivalence across the following parameters: manufacturer (Microchip Technology), series (16V8), programmable type (EE PLD), macrocell count (8), input voltage (5V), speed rating (15 ns), mounting type (Through Hole), and package specification (20-DIP/20-PDIP). The primary distinction between the main part and its substitute lies in packaging format and product status. The ATF16V8B-15PU maintains identical electrical and functional specifications while differing in supplier packaging (Tube versus unspecified for the main part) and product lifecycle status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The ATF16V8B-15PU is the direct functional equivalent of the ATF16V8B-15PC. Selection between these parts should be based on product lifecycle and regulatory compliance requirements. The ATF16V8B-15PC, classified as obsolete, presents procurement risk and limited availability despite current inventory levels. The ATF16V8B-15PU maintains active product status with significantly higher inventory availability (24,212 units versus 5,303 units), ensuring long-term supply chain stability.

Regulatory compliance differs between the two parts. The ATF16V8B-15PU carries ROHS3 compliance certification, while the ATF16V8B-15PC is RoHS non-compliant. For applications subject to RoHS directives or customer specifications requiring RoHS compliance, the ATF16V8B-15PU is the appropriate selection. Both parts maintain identical REACH and ECCN classifications, indicating equivalent export and environmental regulatory status.

Packaging format represents the secondary distinction. The ATF16V8B-15PU is supplied in Tube packaging, which may influence handling, storage, and integration into automated assembly processes compared to the main part specification.

Frequently Asked Questions (FAQ)

Q: Are ATF16V8B-15PC and ATF16V8B-15PU electrically identical?

A: Yes. Both parts share identical electrical specifications: 8 macrocells, 5V input voltage, 15 nanosecond speed rating, and EE PLD programmable type. They are functionally interchangeable at the circuit level.

Q: What is the primary reason to substitute ATF16V8B-15PC with ATF16V8B-15PU?

A: The ATF16V8B-15PC is classified as obsolete, creating procurement and long-term availability risk. The ATF16V8B-15PU is active product with substantially higher inventory levels, ensuring supply chain continuity.

Q: Does the packaging difference between these parts affect circuit performance?

A: No. The packaging format (Tube for ATF16V8B-15PU) does not affect electrical performance or functional operation. Both use identical 20-DIP (0.300", 7.62mm) physical packages suitable for through-hole mounting.

Q: Is RoHS compliance a factor in selecting between these parts?

A: RoHS compliance becomes a selection factor only if your application, customer specification, or regional regulation requires it. The ATF16V8B-15PU is ROHS3 compliant, while the ATF16V8B-15PC is not. For RoHS-mandated applications, the ATF16V8B-15PU is required.

Q: Can I use ATF16V8B-15PU as a direct replacement in existing designs using ATF16V8B-15PC?

A: Yes. Identical pin configuration, voltage specifications, and functional characteristics permit direct substitution without circuit modification.

Q: Are there any environmental or export restrictions affecting these parts?

A: Both parts carry identical REACH and ECCN (EAR99) classifications, indicating equivalent environmental and export regulatory status. No differential restrictions apply between the two parts.
