MAX9691EPA Equivalent & Substitute Parts

Part Overview

The MAX9691EPA is a single-channel comparator with integrated latch functionality, featuring complementary ECL output architecture. Manufactured by Analog Devices Inc./Maxim Integrated, this device operates across the industrial temperature range of -40°C to 85°C and is housed in an 8-DIP through-hole package.

The MAX9691EPA is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance where this comparator is specified in active applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX9691EPA is determined by strict equivalence across the following critical parameters:

Functional Architecture: Single-channel comparator with integrated latch, complementary ECL output configuration

Electrical Performance: Input offset voltage maximum of 6.5mV @ 5V, input bias current maximum of 20µA @ 5V, output current of 50mA typical, quiescent current maximum of 26mA, CMRR of 80dB and PSRR of 60dB, propagation delay maximum of 1.8ns

Physical Form Factor: 8-DIP through-hole package with 0.300" (7.62mm) pitch

Environmental Compliance: ROHS3 compliance, MSL Level 1, REACH unaffected status

Operating Conditions: Industrial temperature range -40°C to 85°C

Parts meeting all these criteria are classified as direct substitutes. Variations in product status (active versus obsolete) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MAX9691EPA+ serves as the direct substitute for the MAX9691EPA. Both parts are electrically and mechanically identical across all specified parameters. The primary distinction is product lifecycle status: the MAX9691EPA is classified as obsolete, while the MAX9691EPA+ maintains active status.

For new designs or system refreshes, the MAX9691EPA+ is the appropriate selection due to its active product status and continued manufacturer support. For legacy system maintenance where the MAX9691EPA is currently specified, the MAX9691EPA+ provides seamless compatibility without design modification.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements. The MSL Level 1 rating indicates unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can MAX9691EPA+ be used as a direct replacement for MAX9691EPA in existing designs?

A: Yes. The MAX9691EPA+ is electrically and mechanically identical to the MAX9691EPA. All electrical parameters, package dimensions, pin configuration, and operating characteristics are equivalent. No circuit modification or PCB redesign is required.

Q: What is the difference between MAX9691EPA and MAX9691EPA+?

A: The parts are functionally identical. The primary difference is product status: MAX9691EPA is obsolete, while MAX9691EPA+ is active. The "+" designation in MAX9691EPA+ indicates the active product variant from Analog Devices Inc./Maxim Integrated.

Q: Are there any packaging differences between these parts?

A: The MAX9691EPA is supplied in standard packaging, while the MAX9691EPA+ is supplied in tube packaging. Both use the same 8-DIP through-hole form factor with 0.300" (7.62mm) pitch. Tube packaging does not affect electrical performance or board-level compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MAX9691EPA and MAX9691EPA+ are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 rating. Environmental and regulatory compliance is identical.

Q: What is the propagation delay specification for these comparators?

A: The maximum propagation delay is 1.8ns for both parts. This specification defines the time interval between input signal transition and output response in the comparator with latch configuration.

Q: Can these parts operate across the full industrial temperature range?

A: Yes. Both MAX9691EPA and MAX9691EPA+ are rated for operation from -40°C to 85°C, covering the industrial temperature range. Electrical parameters are specified at 5V supply voltage within this temperature band.
