EE-SPX303 Equivalent & Substitute Parts

Part Overview

The EE-SPX303 is an optical sensor module manufactured by Omron Automation and Safety, designed for through-beam sensing applications with a 0.512" (13mm) sensing distance. This component features NPN open collector output with dark-ON configuration and operates across a 5V to 24V supply voltage range in a slotted chassis mount package.

The EE-SPX303 has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain system functionality, ensure supply chain continuity, and support ongoing maintenance and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EE-SPX303 is determined by the following critical parameters:

• Sensing Distance: 0.512" (13mm) — must match exactly
• Sensing Method: Through-beam configuration — must match exactly
• Package / Case: Module, Slotted — must match exactly
• Mounting Type: Chassis Mount — must match exactly
• Output Configuration: NPN output topology — must be compatible
• Voltage - Supply Range: Must encompass or be compatible with the original 5V ~ 24V range

The EE-SPX303N qualifies as a direct substitute based on matching sensing distance, through-beam method, slotted module package, and chassis mount configuration. While the EE-SPX303N offers selectable output configuration (Dark-ON/Light-ON) compared to the fixed dark-ON output of the original part, it maintains NPN open collector topology and operates within a compatible voltage range (12V ~ 24V).

Parameter Comparison

Engineering Selection Recommendations

The EE-SPX303N is the direct substitute for the obsolete EE-SPX303. Both components share identical sensing distance, through-beam methodology, slotted module packaging, and chassis mount configuration.

The EE-SPX303N carries active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The selectable output configuration (Dark-ON/Light-ON) in the EE-SPX303N provides operational flexibility beyond the fixed dark-ON output of the original part.

The voltage supply range of the EE-SPX303N (12V ~ 24V) is narrower than the original (5V ~ 24V). Applications requiring 5V operation must be evaluated for compatibility or alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the EE-SPX303N directly replace the EE-SPX303 in existing designs?

A: Yes. The EE-SPX303N maintains identical sensing distance (0.512"/13mm), through-beam sensing method, slotted module package, and chassis mount configuration. Verify that your application operates within the 12V ~ 24V supply voltage range of the substitute part.

Q: What is the key difference between the EE-SPX303 and EE-SPX303N?

A: The primary difference is output configuration flexibility. The EE-SPX303 provides fixed dark-ON output, while the EE-SPX303N offers selectable dark-ON or light-ON output. Both maintain NPN open collector topology.

Q: Does the EE-SPX303N support 5V operation?

A: No. The EE-SPX303N operates within 12V ~ 24V supply voltage range. The original EE-SPX303 supported 5V ~ 24V. Applications requiring 5V operation require alternative component evaluation.

Q: What is the inventory status of these parts?

A: The EE-SPX303 (obsolete) has 752 pieces in stock. The EE-SPX303N (active) has 1900 pieces in stock.

Q: Are there compliance differences between these parts?

A: The EE-SPX303N is ROHS3 compliant and REACH affected, providing modern regulatory compliance. The EE-SPX303 is REACH unaffected with unspecified RoHS status.
