MAX902CPD Equivalent & Substitute Parts

Part Overview

The MAX902CPD is a dual comparator with integrated latch functionality, designed for TTL-level output applications. This device operates across a wide supply voltage range (5V ~ 10V single supply, ±2.5V ~ 5V dual supply) and is housed in a 14-pin DIP package for through-hole mounting. The MAX902CPD is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution of the MAX902CPD is determined by strict equivalence across the following critical parameters:

• Dual comparator architecture with integrated latch function
• TTL output configuration
• Supply voltage range: 5V ~ 10V (single), ±2.5V ~ 5V (dual)
• Input offset voltage: 4mV @ ±5V maximum
• Input bias current: 10µA maximum
• Quiescent current specifications: 8mA, 6mA, 3mA
• Common-mode rejection ratio: 82.5dB minimum
• Power supply rejection ratio: 80dB minimum
• Operating temperature range: 0°C ~ 70°C
• 14-pin DIP package with 0.300" (7.62mm) pitch
• Through-hole mounting configuration

The MAX902CPD+ is a direct functional equivalent manufactured by the same supplier, maintaining identical electrical specifications and package geometry while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The MAX902CPD+ is a direct substitute for the MAX902CPD. Both devices maintain identical electrical specifications, package configuration, and compliance certifications. The primary distinction is product status: the MAX902CPD is obsolete while the MAX902CPD+ is active.

For new designs and production continuity, the MAX902CPD+ is the appropriate selection due to its active status and assured long-term availability. Both parts satisfy ROHS3 compliance and REACH requirements, ensuring regulatory alignment for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can MAX902CPD+ be used as a direct replacement for MAX902CPD in existing designs?

A: Yes. The MAX902CPD+ is electrically and mechanically identical to the MAX902CPD. Pin configuration, electrical performance, and package dimensions are equivalent, enabling direct substitution without circuit modification.

Q: What is the significance of the "+" designation in MAX902CPD+?

A: The "+" suffix indicates the active production variant of the MAX902 base product. This designation reflects current manufacturing status and packaging configuration (tube packaging for MAX902CPD+).

Q: Are there any compliance or certification differences between these parts?

A: No. Both the MAX902CPD and MAX902CPD+ maintain identical RoHS3 compliance, REACH status, and moisture sensitivity ratings. Regulatory requirements are satisfied by either part.

Q: Why is the MAX902CPD classified as obsolete?

A: Obsolescence reflects the manufacturer's discontinuation of this specific part number variant. The MAX902CPD+ represents the active continuation of this product line with equivalent functionality.

Q: What packaging differences exist between MAX902CPD and MAX902CPD+?

A: The MAX902CPD+ is supplied in tube packaging, while the original MAX902CPD packaging is not specified in the technical data. Both maintain the identical 14-DIP (0.300", 7.62mm) physical package for through-hole mounting.

Q: Are the electrical specifications guaranteed to be identical?

A: Yes. Input offset voltage, input bias current, quiescent current, CMRR, PSRR, and all other electrical parameters are specified identically across both part numbers.
