Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATF16V8BQL-15JC is determined by strict equivalence across the following critical parameters:

• Series and Base Product Number: Both parts belong to the ATF16V8 series, ensuring functional compatibility at the architecture level
• Programmable Type: EE PLD (Electrically Erasable Programmable Logic Device) designation must remain constant
• Macrocell Count: 8 macrocells required for pin-compatible operation
• Speed Rating: 15 ns propagation delay maintains timing specifications
• Input Voltage: 5V supply voltage compatibility
• Package Configuration: 20-PLCC (9x9) surface mount package ensures mechanical and electrical pin compatibility
• Mounting Type: Surface mount designation confirms PCB assembly compatibility

The substitute part ATF16V8BQL-15JU meets all these criteria while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The ATF16V8BQL-15JU is the direct functional equivalent of the ATF16V8BQL-15JC. All critical electrical and mechanical parameters are identical, ensuring drop-in compatibility in existing circuit designs.

Advantages of ATF16V8BQL-15JU:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance satisfies modern environmental and regulatory requirements
• Verified programmable status through DiGi-Electronics confirms reliable programming capability
• Higher inventory availability (3786 pcs vs. 1634 pcs) supports procurement timelines

Compliance Considerations:

Both parts maintain REACH Unaffected status and EAR99 export classification. The substitute part's ROHS3 compliance provides regulatory advantage for new designs and systems subject to environmental directives.

Frequently Asked Questions (FAQ)

Q: Can ATF16V8BQL-15JU be used as a direct replacement for ATF16V8BQL-15JC?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters: 8 macrocells, 15 ns speed, 5V input, and 20-PLCC package configuration. Pin-for-pin compatibility is confirmed.

Q: What is the difference between the -15JC and -15JU suffix designations?

A: The suffix indicates packaging and compliance variations. The -15JU variant features ROHS3 compliance and verified programmable status, while the -15JC is non-compliant. Both maintain identical electrical specifications and package dimensions.

Q: Does the moisture sensitivity level difference affect circuit performance?

A: Moisture sensitivity level (MSL) affects component storage and handling requirements, not circuit performance. MSL 3 (168 Hours) for the -15JU requires shorter time-to-reflow windows compared to MSL 2 (1 Year) for the -15JC. Storage conditions must comply with the respective MSL rating.

Q: Are there any programming differences between these parts?

A: No. Both parts are EE PLD (Electrically Erasable Programmable Logic Device) with identical architecture. The -15JU carries verified programmable status, confirming reliable programming capability through standard ATF16V8 programming equipment.

Q: What is the impact of RoHS compliance on system design?

A: ROHS3 compliance of the -15JU eliminates restricted substances (lead, cadmium, mercury, etc.), supporting regulatory compliance for systems subject to environmental directives. The non-compliant -15JC may require additional documentation for legacy system support.
