MAX951EPA Equivalent & Substitute Parts

Part Overview

The MAX951EPA is a linear amplifier, comparator, and reference integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This device is designed for smart card applications and is packaged in an 8-DIP (0.300", 7.62mm) through-hole configuration. The MAX951EPA is classified as an obsolete product, making identification of equivalent and substitute parts essential for ongoing system support, maintenance, and component procurement in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX951EPA is determined by strict alignment of the following parameters:

Critical Substitution Parameters:

• Device Type: Amplifier, Comparator, Reference
• Package / Case: 8-DIP (0.300", 7.62mm)
• Supplier Device Package: 8-PDIP
• Mounting Type: Through Hole
• Base Product Number: MAX951
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts must match all critical parameters to ensure functional and mechanical compatibility within the original application circuit. Packaging format (Tube vs. other configurations) does not affect electrical or mechanical substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The MAX951EPA+ is a direct substitute for the MAX951EPA based on complete parameter alignment across all critical electrical, mechanical, and compliance specifications. Both devices share identical device classification, package configuration, mounting methodology, and regulatory compliance status.

The primary distinction between these parts is packaging format: MAX951EPA is supplied in standard packaging, while MAX951EPA+ is supplied in Tube packaging. This difference affects only logistics and handling procedures and does not impact electrical performance or mechanical compatibility within the application circuit.

For component selection in legacy smart card applications requiring the MAX951 amplifier, comparator, and reference functionality in 8-DIP through-hole configuration, either MAX951EPA or MAX951EPA+ may be selected interchangeably based on packaging availability and procurement requirements.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with current environmental and hazardous substance restrictions.

Frequently Asked Questions (FAQ)

Q: Can MAX951EPA+ be used as a direct replacement for MAX951EPA?

A: Yes. The MAX951EPA+ is a direct substitute for MAX951EPA. All electrical specifications, device functionality, package dimensions, pin configuration, and compliance certifications are identical. The only difference is packaging format (Tube).

Q: What does the "+" designation in MAX951EPA+ indicate?

A: The "+" designation indicates a packaging or distribution variant. In this case, MAX951EPA+ is supplied in Tube packaging, whereas MAX951EPA uses standard packaging. The electrical and mechanical specifications remain unchanged.

Q: Are there any pin configuration differences between MAX951EPA and MAX951EPA+?

A: No. Both devices use the 8-PDIP package configuration with identical pin assignments and functionality. They are mechanically and electrically interchangeable.

Q: Why is the MAX951EPA classified as obsolete?

A: The MAX951EPA is an older product line that has been discontinued by the manufacturer. Obsolete status indicates that new production has ceased, though existing inventory may remain available through authorized distributors.

Q: Does the packaging format affect circuit board compatibility?

A: No. Packaging format (Tube vs. standard) affects only component handling, storage, and delivery logistics. Once installed on a circuit board, both MAX951EPA and MAX951EPA+ function identically and occupy the same physical footprint.

Q: Are both parts RoHS compliant?

A: Yes. Both MAX951EPA and MAX951EPA+ are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: Can these parts be used in new designs?

A: Both MAX951EPA and MAX951EPA+ are classified as obsolete products. While they may be available through existing inventory channels, they are not recommended for new design implementations. Current design work should evaluate active product alternatives from Analog Devices Inc./Maxim Integrated.
