Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GP-A8S is determined by the following critical parameters:

• Sensing Distance: 0.079" (2mm) — exact match required
• Output Configuration: NPN - Open Collector — exact match required
• Voltage Supply Range: 21.6V ~ 26.4V — must encompass or match the operating range
• Current Supply: 150 mA — must support or exceed this requirement
• Package Type: Module, Wire Leads — physical and electrical interface compatibility
• RoHS Compliance: Required for regulatory alignment

The GP-XC8S meets all critical substitution criteria. While the GP-XC8S operates within a narrower temperature range (0°C ~ 50°C versus -10°C ~ 55°C), it maintains full electrical and mechanical compatibility for standard industrial applications within its specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The GP-XC8S is the qualified substitute for the obsolete GP-A8S based on the following engineering criteria:

• Electrical Compatibility: Identical voltage supply range (21.6V ~ 26.4V), current rating (150 mA), and output configuration (NPN - Open Collector) ensure direct functional replacement.
• Physical Compatibility: Both components use Module, Wire Leads packaging, maintaining identical form factor and interface requirements.
• Regulatory Compliance: Both parts are RoHS Compliant, meeting current environmental and regulatory standards.
• Product Availability: The GP-XC8S is currently in active production status with 817 units in stock, ensuring supply chain continuity.
• Temperature Operating Range: The GP-XC8S operates within 0°C ~ 50°C. Applications requiring the extended lower temperature range (-10°C) of the original GP-A8S require verification of actual system operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the GP-XC8S directly replace the GP-A8S in existing designs?

A: Yes, for applications operating within the 0°C ~ 50°C temperature range. The electrical specifications, output configuration, sensing distance, and package type are identical. If your system operates below 0°C, verify actual operating conditions before substitution.

Q: Are there any differences in sensing method between these parts?

A: The GP-A8S sensing method is not specified in the available data. The GP-XC8S is specified as Through-Beam sensing. Both maintain the same 0.079" (2mm) sensing distance and NPN open collector output, ensuring functional compatibility.

Q: What is the impact of the narrower temperature range on the GP-XC8S?

A: The GP-XC8S operates from 0°C ~ 50°C compared to the GP-A8S range of -10°C ~ 55°C. Substitution is valid only if your application operates within the 0°C ~ 50°C envelope. Confirm actual system operating temperatures before implementation.

Q: Are both parts RoHS Compliant?

A: Yes, both the GP-A8S and GP-XC8S are RoHS Compliant, meeting current environmental standards for electronic components.

Q: What is the packaging difference between these parts?

A: Both parts use Module, Wire Leads packaging. The GP-A8S is supplied without specified packaging, while the GP-XC8S is supplied in Box packaging. The electrical and physical interfaces remain identical.
