Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the E3X-DA9-S are identified based on the following critical parameters that determine functional compatibility:

• Amplifier Type: Standard
• Voltage Supply Range: 12V ~ 24V (or compatible overlapping range)
• Output Type: PNP or PNP-compatible configurations
• Operating Temperature Range: -25°C ~ 55°C (TA)
• Manufacturer: Omron Automation and Safety
• Moisture Sensitivity Level: 1 (Unlimited)

The E3X-HD8 and E3NX-FA9TW meet these substitution criteria through matching or compatible electrical specifications and environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete E3X-DA9-S, the following active alternatives are available:

E3X-HD8 provides direct voltage supply compatibility (12V ~ 24V) with identical operating temperature range and MSL rating. This part features PNP - Open Collector output configuration and increased current supply capacity (60 mA versus 40 mA). The E3X-HD8 is currently in active production status with RoHS3 compliance and REACH affected designation.

E3NX-FA9TW offers extended voltage supply range (10V ~ 30V), encompassing the original 12V ~ 24V specification. This part maintains identical operating temperature and MSL ratings. The E3NX-FA9TW is actively produced and provides broader supply voltage flexibility for system integration.

Both substitute parts are manufactured by Omron Automation and Safety and carry identical export classification (EAR99) and moisture sensitivity ratings as the original component.

Frequently Asked Questions (FAQ)

Q: Can the E3X-HD8 directly replace the E3X-DA9-S in existing installations?

A: The E3X-HD8 shares identical supply voltage range (12V ~ 24V) and operating temperature specifications (-25°C ~ 55°C). Both feature PNP output configuration. The E3X-HD8 supplies higher current capacity (60 mA versus 40 mA), which is compatible with systems designed for the original 40 mA specification. Mechanical mounting and connector compatibility must be verified for your specific application.

Q: What is the advantage of the E3NX-FA9TW over the E3X-HD8?

A: The E3NX-FA9TW provides extended supply voltage range (10V ~ 30V) compared to the E3X-HD8 (12V ~ 24V). This broader range offers greater flexibility in systems with variable supply voltages. Both parts maintain identical operating temperature and moisture sensitivity ratings.

Q: Are there packaging differences between these substitute parts?

A: Yes. The E3X-DA9-S was supplied in standard packaging. The E3X-HD8 is packaged in Box format, while the E3NX-FA9TW is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Do all three parts share the same compliance certifications?

A: All three parts carry EAR99 export classification and MSL rating of 1 (Unlimited). The E3X-HD8 additionally carries RoHS3 compliance and REACH affected designation. These certifications do not affect functional substitution.

Q: What inventory status should I consider when selecting a substitute?

A: The E3X-HD8 has 1159 units in stock, while the E3NX-FA9TW has 773 units available. Both are actively produced. Component availability should be evaluated based on your procurement timeline and system requirements.
