MAX457EPA Equivalent & Substitute Parts

Part Overview

The MAX457EPA is a general-purpose video amplifier integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This device contains two independent amplifier circuits in an 8-pin DIP package and is designed for general-purpose amplification applications. The MAX457EPA is classified as obsolete, which necessitates identification of equivalent substitute components for ongoing design support and procurement requirements. The active product variant MAX457EPA+ provides functional continuity for new designs and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX457EPA is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Number of Circuits: 2 channels
• -3dB Bandwidth: 70 MHz
• Slew Rate: 300 V/µs
• Current - Supply: 35 mA
• Current - Output / Channel: 20 mA
• Voltage - Supply, Single/Dual (±): ±4.5V ~ 5.5V

Physical and Mechanical Specifications:

• Mounting Type: Through Hole
• Package / Case: 8-DIP (0.300", 7.62mm)
• Supplier Device Package: 8-PDIP

The MAX457EPA+ qualifies as a direct substitute because it maintains identical electrical performance parameters and physical packaging specifications. The primary distinction is product status and compliance certification, not functional capability.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Component Replacement: The MAX457EPA+ is the direct functional equivalent for applications currently using the MAX457EPA. All electrical and mechanical parameters are identical, ensuring pin-for-pin compatibility and circuit-level interchangeability.

For New Designs: The MAX457EPA+ is the appropriate selection due to its active product status. This ensures long-term availability, manufacturer support, and compliance with current regulatory requirements.

Compliance Considerations: The MAX457EPA+ achieves ROHS3 compliance, whereas the MAX457EPA is RoHS non-compliant. Both devices maintain REACH Unaffected status and EAR99 export classification. Organizations subject to RoHS requirements must use MAX457EPA+.

Packaging and Procurement: The MAX457EPA+ is supplied in Tube packaging, which differs from the original MAX457EPA packaging specification. Both variants use identical 8-PDIP physical packages suitable for through-hole mounting on standard PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can MAX457EPA+ be used as a direct replacement for MAX457EPA in existing designs?

A: Yes. The MAX457EPA+ provides complete electrical and mechanical equivalence. All performance parameters, supply voltage ranges, output current ratings, bandwidth specifications, and slew rate characteristics are identical. The 8-PDIP package dimensions and pin configuration are unchanged, enabling direct PCB substitution.

Q: What is the primary reason to transition from MAX457EPA to MAX457EPA+?

A: The MAX457EPA is classified as obsolete, limiting future availability and manufacturer support. The MAX457EPA+ is an active product with ongoing production and supply chain continuity. Additionally, MAX457EPA+ achieves ROHS3 compliance, meeting current regulatory standards.

Q: Are there any electrical performance differences between these parts?

A: No. Both devices specify identical -3dB bandwidth of 70 MHz, slew rate of 300 V/µs, supply current of 35 mA, output current per channel of 20 mA, and dual supply voltage range of ±4.5V to ±5.5V.

Q: What packaging differences exist between MAX457EPA and MAX457EPA+?

A: The MAX457EPA+ is supplied in Tube packaging, while the original MAX457EPA packaging specification is not detailed in the component data. Both use the same 8-DIP (0.300", 7.62mm) physical package format. Tube packaging is standard for active production components and does not affect circuit performance or PCB mounting.

Q: Does the RoHS compliance difference affect circuit functionality?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. Both devices function identically in circuit applications. However, RoHS3 compliance of MAX457EPA+ is required for applications subject to RoHS regulations.

Q: Are both parts suitable for general-purpose amplification applications?

A: Yes. Both MAX457EPA and MAX457EPA+ are specified for general-purpose applications. The dual-channel configuration, 70 MHz bandwidth, and 300 V/µs slew rate support video amplification and general signal conditioning tasks within the specified supply voltage and current parameters.
