Key Parameters

Substitute Part Grouping Explanation

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

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

The substitute part ATF16V8BQL-15SU meets all these criteria, differing only in packaging format (Tube versus unspecified for the main part) and product status classifications. Both parts are manufactured by Microchip Technology within the 16V8 series and maintain identical electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ATF16V8BQL-15SU is the direct functional equivalent of the ATF16V8BQL-15SC. Selection between these parts should be based on the following factors:

Product Status: The ATF16V8BQL-15SC is classified as obsolete, while the ATF16V8BQL-15SU maintains active product status. For new designs or long-term production requirements, the active status part is preferred for supply chain continuity.

Compliance Certifications: The ATF16V8BQL-15SU is ROHS3 compliant, whereas the ATF16V8BQL-15SC is RoHS non-compliant. Applications subject to RoHS regulations require the compliant substitute.

Programmable Verification: The ATF16V8BQL-15SU is verified as programmable by DiGi-Electronics, while the ATF16V8BQL-15SC verification status is not confirmed. This verification status may be relevant for programming and configuration workflows.

Both parts share identical electrical performance, package dimensions, and thermal characteristics, ensuring direct substitution at the circuit board level.

Frequently Asked Questions (FAQ)

Q: Can ATF16V8BQL-15SU replace ATF16V8BQL-15SC in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent, featuring identical macrocell count, input voltage, propagation delay, and 20-SOIC package dimensions. Direct substitution is possible without circuit modifications.

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

A: The primary differences are product status (obsolete versus active), RoHS compliance classification (non-compliant versus ROHS3 compliant), and packaging format (unspecified versus Tube). Electrical and functional specifications are identical.

Q: Why should I use ATF16V8BQL-15SU instead of ATF16V8BQL-15SC?

A: The ATF16V8BQL-15SU offers active product status for improved supply availability, ROHS3 compliance for regulatory adherence, and verified programmability. These factors support long-term production and regulatory requirements.

Q: Are there any package or pinout differences?

A: No. Both parts use the 20-SOIC package with identical 0.295" width and 7.50mm dimensions. Pinout and mechanical compatibility are fully maintained.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 2 rating with a 1-year floor life. Standard moisture control procedures during storage and handling apply to both components.
