MAX310C/D Equivalent & Substitute Parts Reference

Part Overview

The MAX310C/D is an RF video multiplexer IC manufactured by Analog Devices Inc./Maxim Integrated, designed for video switching applications. This die-form component functions as a 1-channel video switch with 8:1 multiplexer/demultiplexer capability and break-before-make switching characteristics. The MAX310C/D is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing system support. Substitute parts must maintain functional compatibility while offering improved product status and extended availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX310C/D is based on the following critical parameters that define functional equivalence:

• Multiplexer Configuration: 8:1 multiplexer/demultiplexer circuit with 1 channel
• Switching Characteristics: Break-before-make feature preservation
• On-State Resistance: Maximum 250Ω specification
• Supply Voltage Compatibility: Dual supply voltage range overlap (±4.5V minimum)
• Base Product Number: MAX310 series designation
• Switching Function: Video multiplexer IC for RF/video applications

The MAX310EWN+ qualifies as a manufacturer-recommended substitute because it maintains all core functional parameters while offering active product status and extended operating temperature range. The primary difference is packaging format (18-SOIC vs. die form) and expanded supply voltage specifications.

Engineering Selection Recommendations

The MAX310EWN+ is the manufacturer-recommended substitute for the obsolete MAX310C/D. Selection should be based on the following factors:

Product Status: The MAX310C/D is obsolete with limited remaining inventory (680 pcs). The MAX310EWN+ maintains active product status with established supply channels (787 pcs in stock), ensuring long-term availability for production and support applications.

Functional Equivalence: Both parts share identical core specifications for multiplexer configuration (8:1), channel count (1), on-state resistance (250Ω maximum), and break-before-make switching characteristics. These parameters define the video switching function and are preserved in the substitute.

Compliance: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with current manufacturing and storage requirements.

Operating Envelope: The MAX310EWN+ provides expanded operating temperature range (-40°C to 85°C versus 0°C to 70°C) and dual supply voltage range (±4.5V to 18V versus ±4.5V to 16.5V), offering greater design flexibility without compromising the original specification envelope.

Package Consideration: The MAX310EWN+ is supplied in 18-SOIC package format rather than die form. Applications requiring die-form components must evaluate alternative MAX310 variants or assess feasibility of package conversion through qualified assembly partners.

Frequently Asked Questions (FAQ)

Q: Can the MAX310EWN+ directly replace the MAX310C/D in all applications?

A: The MAX310EWN+ maintains functional equivalence for video multiplexer applications requiring 8:1 switching with break-before-make characteristics and 250Ω maximum on-state resistance. The primary consideration is package form factor: the MAX310EWN+ is supplied as 18-SOIC, while the MAX310C/D is die form. Applications designed for die-form components require package conversion or alternative MAX310 variants.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: (1) 8:1 multiplexer/demultiplexer configuration, (2) 1-channel architecture, (3) 250Ω maximum on-state resistance, (4) break-before-make switching feature, (5) dual supply voltage range with minimum ±4.5V capability, and (6) MAX310 base product number designation. All parameters must be maintained for functional equivalence.

Q: Does the expanded operating temperature range of the MAX310EWN+ affect compatibility?

A: No. The MAX310EWN+ operating temperature range (-40°C to 85°C) encompasses the original MAX310C/D specification (0°C to 70°C). The expanded range provides additional design margin and is fully backward compatible with applications designed for the narrower temperature window.

Q: Are there supply voltage differences that affect circuit design?

A: The MAX310EWN+ dual supply voltage range (±4.5V to 18V) is compatible with and extends beyond the MAX310C/D specification (±4.5V to 16.5V). Both parts support the same minimum supply voltage (±4.5V). The MAX310EWN+ permits operation at ±18V, offering additional design flexibility without requiring circuit modifications for existing ±4.5V to ±16.5V applications.

Q: What compliance certifications are maintained in the substitute part?

A: Both the MAX310C/D and MAX310EWN+ maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. The MAX310EWN+ carries REACH Unaffected status and EAR99 export classification, consistent with current regulatory requirements for active components.

Q: How should package form factor differences be addressed in design transitions?

A: Applications currently using die-form MAX310C/D components should evaluate: (1) feasibility of transitioning to 18-SOIC package format through PCB redesign, (2) availability of alternative MAX310 variants in die form from the manufacturer, or (3) engagement with qualified assembly partners for package conversion services. The functional specifications remain identical across package formats within the MAX310 product line.
