Substitute Part Grouping Explanation

Substitution of the MAX9691EUA-T is determined by strict equivalence across all electrical and mechanical parameters. The allowed substitution criteria are:

• Identical comparator architecture with latch functionality
• Matching output type: Complementary, ECL
• Equivalent electrical performance: Input offset voltage, input bias current, output current, quiescent current, CMRR, PSRR, and propagation delay
• Identical operating temperature range: -40°C ~ 85°C
• Same package configuration: 8-TSSOP, 8-MSOP with 0.118" (3.00mm) width
• Surface mount mounting type
• Matching RoHS3 compliance and REACH unaffected status
• MSL rating of 1 (Unlimited)

The MAX9691EUA+T qualifies as a direct substitute based on complete parameter alignment across all specified criteria.

Engineering Selection Recommendations

The MAX9691EUA+T is the appropriate selection for applications currently using or requiring the MAX9691EUA-T. The substitute part maintains active product status with Analog Devices Inc./Maxim Integrated, ensuring long-term availability and supply chain continuity. Both parts carry identical ROHS3 compliance and REACH unaffected certifications, meeting regulatory requirements for industrial and commercial applications. The primary distinction is packaging format: the substitute is supplied in Tape & Reel configuration, which is standard for production environments and offers improved handling efficiency compared to tube packaging.

Frequently Asked Questions (FAQ)

Q: Can MAX9691EUA+T replace MAX9691EUA-T in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including input offset voltage, bias current, output current, propagation delay, and operating temperature range. Pin configuration and package dimensions are identical.

Q: What is the difference between MAX9691EUA-T and MAX9691EUA+T?

A: The primary difference is product status and packaging format. MAX9691EUA-T is obsolete and supplied in tube packaging. MAX9691EUA+T is active and supplied in Tape & Reel format. All electrical specifications and package dimensions are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited). Regulatory requirements are met by either part.

Q: Is the 8-uMAX/uSOP package compatible with standard PCB assembly equipment?

A: Yes. The 8-TSSOP, 8-MSOP package with 0.118" (3.00mm) width is a standard surface mount configuration compatible with conventional pick-and-place and reflow assembly processes.

Q: What is the significance of the 1.8ns propagation delay specification?

A: The 1.8ns maximum propagation delay defines the response time of the comparator output to input signal changes. This specification is identical between the main part and substitute, ensuring equivalent timing performance in high-speed applications.
