MAX4580EPE Equivalent & Substitute Parts

Part Overview

The MAX4580EPE is a 2-circuit IC switch with SPST-NC (Single Pole Single Throw - Normally Closed) configuration, rated for 1.25Ohm on-state resistance. This component is classified as obsolete by the manufacturer. Due to its obsolete status, identifying functionally compatible substitute parts is essential for design continuity and procurement planning. Substitute parts must maintain electrical compatibility across switching characteristics, voltage ratings, and package specifications while meeting current manufacturing and compliance standards.

Substitute Part Grouping Explanation

Substitute parts for the MAX4580EPE are identified based on the following critical parameters that determine functional compatibility:

Switch Circuit Configuration: SPST - NC topology (2 circuits required)
On-State Resistance: Maximum 1.25Ohm (primary electrical characteristic)
Supply Voltage Ratings: Single supply 4.5V ~ 36V and dual supply ±4.5V ~ 20V
Package Type: 16-DIP (0.300", 7.62mm) for mechanical compatibility
Operating Temperature Range: Minimum -40°C ~ 85°C coverage

Two substitute parts meet these criteria:

MAX4680CPE+: Matches on-state resistance (1.25Ohm), package, and voltage ratings. Active product status with RoHS3 compliance. Operating temperature range is 0°C ~ 70°C, which is narrower than the original.
MAX4607EPE+: Differs in on-state resistance (2.5Ohm maximum), which is higher than the original specification. Maintains package, voltage ratings, and operating temperature range (-40°C ~ 85°C). Active product status with RoHS3 compliance.

Engineering Selection Recommendations

MAX4680CPE+ is the primary substitute for direct replacement. It maintains identical on-state resistance (1.25Ohm), package configuration, and voltage supply ratings. The component is active and RoHS3 compliant. The operating temperature range (0°C ~ 70°C) is narrower than the original; applications requiring operation below 0°C or above 70°C must account for this limitation.

MAX4607EPE+ is an alternative substitute when on-state resistance of 2.5Ohm is acceptable for the application. This part maintains the full operating temperature range (-40°C ~ 85°C) and offers faster switch times (110ns, 150ns) compared to the original. The component is active and RoHS3 compliant. Applications sensitive to on-state resistance must evaluate whether the 2× increase in resistance is compatible with circuit performance.

Both substitutes are RoHS3 compliant, addressing environmental and regulatory requirements that the obsolete MAX4580EPE does not meet.

Frequently Asked Questions (FAQ)

Q: Can MAX4680CPE+ be used as a direct replacement for MAX4580EPE?

A: Yes, MAX4680CPE+ is electrically and mechanically compatible. Both parts feature 1.25Ohm on-state resistance, 2-circuit SPST-NC configuration, and 16-DIP packaging. The operating temperature range of MAX4680CPE+ (0°C ~ 70°C) must be verified against application requirements, as it does not extend to -40°C or above 70°C.

Q: What is the key difference between MAX4680CPE+ and MAX4607EPE+?

A: The primary difference is on-state resistance. MAX4680CPE+ maintains 1.25Ohm (matching the original), while MAX4607EPE+ has 2.5Ohm maximum resistance. MAX4607EPE+ offers faster switching times and maintains the full -40°C ~ 85°C operating temperature range. Selection depends on whether the application can tolerate increased on-state resistance.

Q: Are both substitutes compatible with the 16-DIP package of the original part?

A: Yes. Both MAX4680CPE+ and MAX4607EPE+ use 16-DIP (0.300", 7.62mm) packaging, ensuring mechanical and pin compatibility with the original MAX4580EPE.

Q: Do the substitute parts meet RoHS compliance?

A: Yes. Both MAX4680CPE+ and MAX4607EPE+ are RoHS3 compliant, whereas the original MAX4580EPE is RoHS non-compliant. This addresses regulatory requirements for new designs and procurement.

Q: What supply voltage ranges do the substitutes support?

A: Both substitutes support identical supply voltage ratings: single supply 4.5V ~ 36V and dual supply ±4.5V ~ 20V, matching the original MAX4580EPE specifications.
