MAX305EPE Equivalent & Substitute Parts
Part Overview
The MAX305EPE is a 2-circuit IC switch with DPST-NO configuration and 35Ohm on-state resistance, designed for analog signal switching and multiplexing applications. This part is classified as obsolete, making identification of active equivalent components essential for new designs and production continuity. The MAX305EPE operates across single supply (10V to 30V) or dual supply (±4.5V to ±20V) configurations with 150ns/100ns switching times and low charge injection characteristics.

Substitute Part Grouping Explanation
Substitution for the MAX305EPE is determined by strict equivalence across the following critical parameters:
- Switch circuit topology (DPST - NO)
- Multiplexer configuration (2:1)
- On-state resistance specification (35Ohm maximum)
- Channel-to-channel matching tolerance (500mOhm)
- Supply voltage ranges (single and dual configurations)
- Switching time performance (150ns/100ns)
- Charge injection and capacitance characteristics
- Package form factor (16-DIP through-hole)
- Operating temperature range (0°C ~ 70°C)
The MAX305CPE+ meets all electrical and mechanical parameters required for direct substitution. This part maintains identical functional specifications while offering active product status and improved compliance certifications.

Engineering Selection Recommendations
The MAX305CPE+ is the direct parametric equivalent for MAX305EPE replacement. Both parts share identical electrical specifications and mechanical packaging, ensuring pin-for-pin compatibility and functional interchangeability in existing circuit designs.
The MAX305CPE+ offers two significant advantages over the obsolete MAX305EPE:
- Active product status ensures long-term availability and manufacturing support
- ROHS3 compliance satisfies current environmental and regulatory requirements, whereas the MAX305EPE is RoHS non-compliant
Both parts maintain REACH Unaffected status and EAR99 export classification. Selection between these parts should be based on supply chain requirements and regulatory compliance mandates for the target application.
Frequently Asked Questions (FAQ)
Q: Can MAX305CPE+ directly replace MAX305EPE in existing designs?
A: Yes. The MAX305CPE+ is a parametric equivalent with identical electrical performance, switching characteristics, and 16-DIP through-hole package. No circuit modifications are required.
Q: What is the primary reason to transition from MAX305EPE to MAX305CPE+?
