ATF16V8CZ-15SC Equivalent & Substitute Parts

Part Overview

The ATF16V8CZ-15SC is a 16V8 Programmable Logic Device (PLD) IC manufactured by Microchip Technology, featuring 8 macrocells with 15 nanosecond propagation delay in a 20-SOIC surface mount package. This device is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

The ATF16V8CZ-15SC operates at 5V input voltage and is designed for embedded applications requiring programmable logic functionality. Due to its obsolete status, sourcing direct replacements or functionally equivalent alternatives is necessary for maintenance, repair, and new production builds where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATF16V8CZ-15SC is determined by strict equivalence across the following critical parameters:

• Programmable Type: EE PLD (Electrically Erasable Programmable Logic Device)
• Number of Macrocells: 8
• Voltage - Input: 5V
• Speed: 15 ns propagation delay
• Mounting Type: Surface Mount
• Package / Case: 20-SOIC (0.295", 7.50mm Width)
• Series Compatibility: 16V8

The substitute part ATF16V8CZ-15SU meets all electrical and mechanical parameters required for direct substitution. Both parts share identical core functionality, pinout configuration, and performance specifications. The primary distinction lies in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The ATF16V8CZ-15SU is the direct functional equivalent for the obsolete ATF16V8CZ-15SC. Both devices are manufactured by Microchip Technology and share identical electrical specifications and package configurations.

For new designs and active production: The ATF16V8CZ-15SU is the appropriate selection. This part carries Active product status and meets ROHS3 compliance requirements, making it suitable for modern manufacturing environments and regulatory frameworks. The improved Moisture Sensitivity Level (MSL 1 with unlimited shelf life) provides superior storage stability compared to the main part.

For legacy system maintenance: The ATF16V8CZ-15SU provides full backward compatibility with existing designs using the ATF16V8CZ-15SC. No circuit modifications, firmware changes, or board redesign are required. Pin-for-pin and functional equivalence is guaranteed.

Compliance considerations: Systems requiring RoHS compliance should transition to the ATF16V8CZ-15SU. The main part's RoHS non-compliant status may restrict its use in regulated industries and regions with environmental material restrictions.

Frequently Asked Questions (FAQ)

Q: Can the ATF16V8CZ-15SU directly replace the ATF16V8CZ-15SC without circuit modifications?

A: Yes. Both parts are pin-for-pin compatible with identical electrical specifications, operating voltage, speed performance, and package dimensions. No circuit redesign is necessary.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (Obsolete vs. Active), RoHS compliance (non-compliant vs. ROHS3 Compliant), and moisture sensitivity rating (MSL 2 vs. MSL 1). Electrical and functional performance are identical.

Q: Why does the ATF16V8CZ-15SU have a better MSL rating?

A: MSL (Moisture Sensitivity Level) indicates the maximum shelf life under specified storage conditions. MSL 1 with unlimited shelf life provides superior long-term storage stability compared to MSL 2 (1 Year), reducing risk of moisture-induced failures during component handling and assembly.

Q: Are there any programming or configuration differences between these parts?

A: No. Both devices use identical EE PLD (Electrically Erasable Programmable Logic Device) technology with 8 macrocells. Programming algorithms, fuse configurations, and operational characteristics are equivalent.

Q: What packaging formats are available for the substitute part?

A: The ATF16V8CZ-15SU is supplied in Tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Is the ATF16V8CZ-15SU suitable for new product designs?

A: Yes. The Active product status and ROHS3 compliance make this part appropriate for new designs. It provides the same 15 nanosecond performance and 8 macrocell functionality as the obsolete main part.
