Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ATF16V8BQL-15JI is determined by strict equivalence across the following critical parameters:

• Series and Macrocell Count: Both main and substitute parts must belong to the 16V8 series with exactly 8 macrocells
• Speed Rating: Propagation delay must be 15 ns or faster
• Voltage Rating: Input voltage must be 5V
• Package Type: Both parts must use 20-PLCC (9x9) surface mount packaging with 20-LCC J-Lead configuration
• Programmable Type: Both must be EE PLD (Electrically Erasable Programmable Logic Device)

The ATF16V8BQL-15JU meets all substitution criteria and is identified as a direct equivalent. The primary distinction between these parts is product status and compliance certification, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ATF16V8BQL-15JU is the direct functional equivalent for the obsolete ATF16V8BQL-15JI. Selection between these parts should be based on the following factors:

For New Designs and Production: The ATF16V8BQL-15JU is the appropriate choice. This part carries Active product status, ensuring long-term availability and manufacturer support. It meets ROHS3 compliance requirements, which is mandatory for applications subject to RoHS regulations. The verified programmable status confirms compatibility with standard programming equipment and procedures.

For Legacy System Maintenance: The ATF16V8BQL-15JI remains functionally interchangeable with the ATF16V8BQL-15JU at the electrical and logical level. However, the obsolete status and RoHS non-compliance status should be evaluated against regulatory and supply chain requirements for the specific application.

Compliance Considerations: The ATF16V8BQL-15JU provides ROHS3 compliance, whereas the ATF16V8BQL-15JI does not. Both parts are REACH Unaffected and carry the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Frequently Asked Questions (FAQ)

Q: Can the ATF16V8BQL-15JU be used as a direct replacement for the ATF16V8BQL-15JI in existing designs?

A: Yes. Both parts are electrically and functionally equivalent. They share identical macrocell count (8), speed rating (15 ns), voltage specification (5V), and package configuration (20-PLCC 9x9). No design modifications are required for substitution.

Q: What is the difference between the ATF16V8BQL-15JI and ATF16V8BQL-15JU?

A: The parts are functionally identical. The primary differences are product status (Obsolete vs. Active), RoHS compliance (non-compliant vs. ROHS3 Compliant), programmable verification status (Not Verified vs. Verified), and moisture sensitivity level specifications (MSL 2 vs. MSL 3).

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the identical 20-PLCC (9x9) surface mount package with 20-LCC J-Lead configuration. Pinout and footprint are identical.

Q: Why is the ATF16V8BQL-15JI classified as obsolete?

A: The ATF16V8BQL-15JI has reached end-of-life status with Microchip Technology. The ATF16V8BQL-15JU remains in active production and is the recommended part for all new applications.

Q: Does the moisture sensitivity level difference affect substitution?

A: The moisture sensitivity level (MSL 2 vs. MSL 3) reflects different storage and handling requirements but does not affect electrical performance or functional compatibility. Both parts are suitable for standard surface mount assembly processes.

Q: Is programming compatibility maintained between these parts?

A: Yes. Both parts are EE PLD (Electrically Erasable Programmable Logic Device) types. The ATF16V8BQL-15JU carries verified programmable status, confirming compatibility with standard ATF16V8 programming equipment and software.
