Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX951EPA+ is determined by strict alignment of the following critical parameters:

Package Compatibility: The 8-DIP (0.300", 7.62mm) through-hole package is the primary mechanical constraint. Any substitute must use identical pinout and physical dimensions to ensure direct board-level compatibility without layout modifications.

Functional Classification: The device operates as an amplifier, comparator, and reference circuit. Substitutes must provide equivalent functional capability within the smart card application domain.

Compliance & Regulatory Status: RoHS3 compliance, REACH unaffected status, and MSL Level 1 rating establish the environmental and regulatory baseline. Substitutes must maintain or exceed these compliance levels.

Manufacturing Status: As an obsolete product, substitutes are identified from the same manufacturer lineage or equivalent product lines that maintain functional and package compatibility.

Based on the provided input data, the MAX951EPA+ is listed as its own direct substitute, indicating this is the primary reference part for this substitution analysis.

Parameter Comparison

Engineering Selection Recommendations

The MAX951EPA+ is classified as an obsolete product. Component selection for replacement applications must prioritize:

Regulatory Compliance: Any substitute must maintain ROHS3 compliance and REACH unaffected status to satisfy current environmental regulations and supply chain requirements.

Package Integrity: The 8-DIP through-hole package is a fixed requirement. Substitutes must use identical package geometry and pinout to ensure direct compatibility with existing printed circuit board designs.

Functional Equivalence: The amplifier, comparator, and reference functionality must be preserved for smart card applications. Functional specifications must be verified against application requirements.

Availability & Status: Given the obsolete status, component sourcing should prioritize verified inventory from authorized distributors. The current inventory of 855 pieces represents available stock of the original part number.

Frequently Asked Questions (FAQ)

Q: Why is the MAX951EPA+ listed as obsolete?

A: Product obsolescence is determined by the manufacturer. Obsolete status indicates the part is no longer in active production, though existing inventory may remain available through authorized distributors.

Q: Can the MAX951EPA+ be replaced with a different package type?

A: No. The 8-DIP (0.300", 7.62mm) through-hole package is a fixed mechanical requirement. Package changes require circuit board redesign and are outside the scope of direct substitution.

Q: What are the critical parameters for substitution?

A: Package type (8-DIP), mounting method (through-hole), functional classification (amplifier/comparator/reference), RoHS3 compliance, and REACH unaffected status are the primary substitution criteria.

Q: Is the MAX951EPA+ RoHS compliant?

A: Yes. The MAX951EPA+ is ROHS3 compliant and has an MSL rating of 1 (unlimited moisture sensitivity level), indicating no special moisture handling requirements.

Q: Where can the MAX951EPA+ be sourced?

A: Authorized distributors of Analog Devices Inc./Maxim Integrated components maintain inventory. Current stock availability is 855 pieces in tube packaging.

Q: What applications use the MAX951EPA+?

A: The MAX951EPA+ is specified for smart card applications requiring integrated amplification, comparison, and reference functions in a compact through-hole package.
