GP-A5S Optical Sensor: Equivalent & Substitute Parts

Part Overview

The GP-A5S is an optical sensor module manufactured by Panasonic Industrial Automation Sales, designed for 0.039" (1mm) sensing distance applications with NPN open collector output configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, redesign, and procurement planning. The GP-A5S operates within a 21.6V to 26.4V supply voltage range with 150 mA current consumption and supports operating temperatures from -10°C to 55°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GP-A5S is determined by strict alignment of the following critical parameters:

• Sensing Distance: 0.039" (1mm) — exact match required for optical detection range compatibility
• Output Configuration: NPN - Open Collector — electrical interface must remain identical for circuit integration
• Voltage Supply Range: 21.6V ~ 26.4V — power supply compatibility is mandatory
• Current Supply: 150 mA — load characteristics must be equivalent
• Package Type: Module, Wire Leads — physical form factor and connection method must be compatible
• RoHS Compliance: Required for regulatory and procurement standards

The GP-XC5SE qualifies as a substitute based on matching all critical electrical parameters and package configuration. Differences in sensing method (Through-Beam vs. unspecified for GP-A5S), mounting type availability, and operating temperature range do not preclude substitution when the primary sensing distance and electrical interface requirements are met.

Parameter Comparison

Engineering Selection Recommendations

The GP-XC5SE is the designated substitute for the obsolete GP-A5S based on electrical and mechanical parameter equivalence. Both components share identical sensing distance (0.039" / 1mm), output configuration (NPN - Open Collector), supply voltage range (21.6V ~ 26.4V), current consumption (150 mA), and package type (Module, Wire Leads). Both components maintain RoHS compliance and MSL Level 1 rating.

The primary distinction is product status: the GP-A5S is obsolete while the GP-XC5SE is active, ensuring ongoing availability and supply chain continuity. The GP-XC5SE is supplied in Box packaging and operates across a 0°C ~ 50°C temperature range, which encompasses the lower portion of the GP-A5S operating range (-10°C ~ 55°C). For applications requiring the full -10°C to 55°C temperature envelope, thermal performance validation is necessary.

Frequently Asked Questions (FAQ)

Q: Can the GP-XC5SE directly replace the GP-A5S in existing circuits?

A: Yes. Both components share identical electrical specifications: NPN open collector output, 21.6V ~ 26.4V supply voltage, 150 mA current consumption, and 0.039" (1mm) sensing distance. Wire lead connections and module form factor are equivalent, enabling direct substitution in circuit design and PCB layouts.

Q: What is the difference in operating temperature range between these parts?

A: The GP-A5S operates from -10°C to 55°C, while the GP-XC5SE operates from 0°C to 50°C. The GP-XC5SE does not support the -10°C lower limit. Applications requiring operation below 0°C must evaluate alternative solutions or confirm that the 0°C minimum is acceptable for the intended environment.

Q: Are both parts RoHS compliant?

A: Yes. Both the GP-A5S and GP-XC5SE are RoHS compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, meeting regulatory requirements for electronics manufacturing and procurement.

Q: Why is the GP-A5S listed as obsolete?

A: The GP-A5S has reached end-of-life status in the manufacturer's product portfolio. The GP-XC5SE represents the active equivalent within the Panasonic GP-X series, providing continued support and availability for this sensing distance and electrical configuration.

Q: Does packaging format affect substitution?

A: The GP-A5S and GP-XC5SE both use Module, Wire Leads packaging. The GP-XC5SE is supplied in Box packaging format, which is a distribution and storage consideration only and does not affect electrical or mechanical compatibility.
