E3X-DA8 Equivalent & Substitute Parts

Part Overview

The E3X-DA8 is a standard sensor amplifier manufactured by Omron Automation and Safety, designed for expandable digital PNP fiber optic applications with DIN Rail mounting. This part is classified as obsolete, making identification of suitable substitute components essential for system maintenance and new designs requiring equivalent functionality.

The E3X-DA8 operates within a 12V to 24V supply voltage range with a maximum supply current of 40 mA and supports operating temperatures from -25°C to 55°C. Its PNP output configuration and standard amplifier classification define the primary substitution criteria.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the E3X-DA8 are identified based on the following critical parameters that determine functional equivalence:

• Amplifier Type: Standard classification maintained across all substitutes
• Operating Temperature Range: -25°C to 55°C (TA) required for environmental compatibility
• Voltage Supply Range: Compatibility with 12V to 24V operation or broader ranges that encompass this specification
• Output Type: PNP output configuration for signal compatibility
• Mounting Type: DIN Rail mounting for physical installation compatibility
• Moisture Sensitivity Level: MSL 1 (Unlimited) for storage and handling consistency

The E3X-HD8 qualifies as a direct substitute due to matching voltage supply range (12V ~ 24V), identical operating temperature range, PNP output capability, DIN Rail mounting, and equivalent MSL rating. The E3NX-FA8 provides an alternative with an expanded voltage supply range (10V ~ 30V) that encompasses the original specification, matching operating temperature and MSL requirements, though output type specification differs in documentation.

Parameter Comparison

Engineering Selection Recommendations

E3X-HD8 is the primary substitute for the E3X-DA8. Both components share identical voltage supply range (12V ~ 24V), operating temperature specifications (-25°C ~ 55°C), and DIN Rail mounting configuration. The E3X-HD8 maintains active product status and carries ROHS3 compliance and REACH compliance certifications, providing regulatory assurance for new designs and long-term availability. The E3X-HD8 supports higher supply current (60 mA versus 40 mA), which does not restrict compatibility but may provide additional operational margin.

E3NX-FA8 serves as an alternative substitute with an expanded voltage supply range (10V ~ 30V) that fully encompasses the original 12V to 24V specification. This component maintains active product status and identical operating temperature range. The E3NX-FA8 offers broader voltage compatibility for applications with variable supply conditions. Selection between E3X-HD8 and E3NX-FA8 depends on specific application voltage requirements and mounting configuration needs.

Frequently Asked Questions (FAQ)

Q: Why is the E3X-DA8 being discontinued? A: The E3X-DA8 is classified as obsolete. Omron Automation and Safety has transitioned to active product lines including the E3X-HD and E3NX series, which provide equivalent or enhanced functionality with current manufacturing support and regulatory compliance.

Q: Can the E3X-HD8 directly replace the E3X-DA8? A: Yes. The E3X-HD8 maintains the same voltage supply range (12V ~ 24V), operating temperature range (-25°C ~ 55°C), PNP output type, and DIN Rail mounting. Both components have MSL 1 (Unlimited) ratings. The E3X-HD8 supports higher supply current (60 mA), which is compatible with applications designed for the 40 mA specification.

Q: What is the difference between E3X-HD8 and E3NX-FA8? A: The E3X-HD8 maintains the exact voltage supply range of the original part (12V ~ 24V), while the E3NX-FA8 provides an expanded range (10V ~ 30V). The E3X-HD8 explicitly specifies PNP - Open Collector output type. Selection depends on your application's voltage requirements and output configuration needs.

Q: Are there packaging differences between these substitutes? A: Yes. The E3X-DA8 uses standard packaging, E3X-HD8 is supplied in Box packaging, and E3NX-FA8 is supplied in Bulk packaging. Verify packaging requirements for your procurement and inventory management processes.

Q: Do the substitute parts have regulatory compliance certifications? A: The E3X-HD8 carries ROHS3 compliance and REACH compliance certifications. These certifications support use in regulated applications and new product designs. Compliance documentation for the E3NX-FA8 should be verified with the manufacturer for specific regulatory requirements.

Q: What is the inventory status of these substitutes? A: Both E3X-HD8 (1159 Pcs) and E3NX-FA8 (1133 Pcs) are available as new original stock, providing immediate availability for replacement and new designs.
