GP1UX511RK Equivalent & Substitute Parts

Part Overview

The GP1UX511RK is a remote receiver sensor manufactured by SHARP/Socle Technology, designed for infrared signal reception at 38.0kHz with an 8.5m sensing distance. This component is classified as obsolete, making equivalent substitutes necessary for ongoing system maintenance and new design implementations. The through-hole mounting configuration and 4.5V to 5.5V supply voltage range define its operational parameters in legacy and compatible applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GP1UX511RK is determined by the following critical parameters:

• B.P.F. Center Frequency: Must be 38.0kHz to maintain signal compatibility with existing infrared transmission protocols
• Mounting Type: Through hole configuration required for PCB integration compatibility
• Voltage Supply Range: Must accommodate the 4.5V to 5.5V operating window or provide a compatible subset
• Sensing Distance: Minimum 8.5m to maintain or exceed original detection range
• Product Status: Active alternatives preferred for long-term availability and support

The TSOP14438 meets these substitution criteria while offering extended sensing distance (30m), broader voltage tolerance (2.5V ~ 5.5V), and active product status.

Parameter Comparison

Engineering Selection Recommendations

The TSOP14438 serves as a direct functional substitute for the obsolete GP1UX511RK based on the following criteria:

• Frequency Compatibility: Both components operate at 38.0kHz, ensuring signal protocol compatibility
• Mounting Compatibility: Identical through-hole mounting type allows direct PCB integration without layout modifications
• Voltage Tolerance: The TSOP14438 voltage range (2.5V ~ 5.5V) encompasses the GP1UX511RK requirement (4.5V ~ 5.5V)
• Performance Enhancement: Extended sensing distance (30m vs. 8.5m) and broader operating temperature range (-25°C ~ 85°C vs. -10°C ~ 70°C) provide operational advantages
• Compliance Status: Both components maintain MSL 1 rating and RoHS compliance, with TSOP14438 meeting ROHS3 standards
• Product Availability: Active product status of TSOP14438 ensures long-term supply and technical support

Frequently Asked Questions (FAQ)

Q: Can the TSOP14438 directly replace the GP1UX511RK without circuit modifications?

A: Yes. Both components share the same 38.0kHz center frequency, through-hole mounting configuration, and compatible voltage supply ranges. The TSOP14438 voltage range (2.5V ~ 5.5V) fully encompasses the GP1UX511RK specification (4.5V ~ 5.5V).

Q: What are the key differences between these two sensors?

A: The primary differences are sensing distance (TSOP14438: 30m vs. GP1UX511RK: 8.5m), operating temperature range (TSOP14438: -25°C ~ 85°C vs. GP1UX511RK: -10°C ~ 70°C), supply current (TSOP14438: 700µA vs. GP1UX511RK: 600µA), and product status (TSOP14438 is active; GP1UX511RK is obsolete).

Q: Are there any packaging considerations when substituting these parts?

A: Both components use through-hole mounting and maintain MSL 1 (Unlimited) moisture sensitivity levels. No special handling or storage modifications are required when transitioning from GP1UX511RK to TSOP14438.

Q: Does the TSOP14438 meet the same compliance standards as the GP1UX511RK?

A: Both components are RoHS compliant. The TSOP14438 additionally meets ROHS3 standards and is REACH Unaffected, providing enhanced regulatory compliance for current applications.

Q: What is the impact of the increased sensing distance on system design?

A: The TSOP14438 30m sensing distance exceeds the GP1UX511RK 8.5m specification. This enhancement allows operation at greater distances without circuit redesign. System performance remains compatible with applications designed for the original 8.5m range.
