Substitute Part Grouping Explanation

Substitution of the MAX965ESA-T is determined by strict equivalence across the following critical parameters:

• Functional Type: Single-channel comparator with integrated voltage reference
• Output Configuration: Open-drain, rail-to-rail output
• Supply Voltage Range: 1.6V ~ 5.5V
• Electrical Performance: Input offset voltage 7mV @ 5.5V, input bias current 0.05µA @ 5.5V, quiescent current 12µA maximum
• Signal Integrity: CMRR 56.48dB, PSRR 80dB, propagation delay 20µs maximum, hysteresis ±1mV
• Package Specification: 8-SOIC surface mount package with 0.154" width (3.90mm)
• Environmental Compliance: ROHS3 compliant, REACH unaffected, MSL 1

Substitute parts must match all electrical parameters, package dimensions, and mounting specifications without deviation.

Parameter Comparison

Engineering Selection Recommendations

The MAX965ESA+T is a direct parametric equivalent to the MAX965ESA-T. Both devices share identical electrical specifications, operating ranges, and package dimensions. The primary distinction is product status: the MAX965ESA-T is obsolete while the MAX965ESA+T is active in production.

For new designs or replacement applications, the MAX965ESA+T is the appropriate selection. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The packaging format difference (tube versus tape & reel) reflects standard distribution practices and does not affect functional compatibility or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can MAX965ESA+T replace MAX965ESA-T in existing designs?

A: Yes. The MAX965ESA+T is electrically and mechanically identical to the MAX965ESA-T. All electrical parameters, operating ranges, and package specifications are equivalent. The only difference is product status and packaging format.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging (MAX965ESA-T) is used for lower-volume orders and manual assembly. Tape & reel packaging (MAX965ESA+T) is standard for automated pick-and-place assembly. Both formats contain the same component with identical specifications.

Q: Are there any compatibility concerns when switching from MAX965ESA-T to MAX965ESA+T?

A: No compatibility concerns exist. The devices are pin-compatible, functionally identical, and operate across the same supply voltage range and temperature specifications. PCB layout and circuit design require no modification.

Q: Why is the MAX965ESA-T listed as obsolete?

A: Obsolescence reflects manufacturing discontinuation. The MAX965ESA+T remains in active production and serves as the current equivalent for this comparator function.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both MAX965ESA-T and MAX965ESA+T are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) classification.
