GL100MN1MP1 Equivalent & Substitute Parts

Part Overview

The GL100MN1MP1 is an infrared (IR) emitter operating at 940nm wavelength, designed for surface mount applications requiring 50mA maximum forward current at 1.2V typical forward voltage. Manufactured by SHARP/Socle Technology, this component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The 2-SMD, No Lead package with 20° viewing angle serves applications in proximity sensing, remote control, and IR communication systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GL100MN1MP1 is determined by the following critical parameters:

• Wavelength: Must remain 940nm for optical system compatibility
• Package / Case: Must be 2-SMD, No Lead for PCB assembly compatibility
• Mounting Type: Must be Surface Mount
• Forward Voltage (Vf): 1.2V typical ensures circuit compatibility
• Operating Temperature Range: Must support the required thermal envelope
• RoHS Compliance: Required for regulatory and supply chain requirements

The IR42-21C/TR8 from Everlight Electronics Co Ltd meets these core substitution criteria while maintaining functional equivalence in the 940nm IR emitter category.

Parameter Comparison

Engineering Selection Recommendations

The IR42-21C/TR8 serves as a direct functional substitute for the GL100MN1MP1 based on the following factors:

• Product Status: The IR42-21C/TR8 maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete GL100MN1MP1
• Compliance: Both components meet RoHS requirements; the IR42-21C/TR8 carries ROHS3 Compliant certification with REACH Unaffected status, providing enhanced regulatory alignment
• Electrical Compatibility: Identical forward voltage (1.2V typical) and wavelength (940nm) ensure direct circuit compatibility
• Package Equivalence: Both utilize 2-SMD, No Lead surface mount packages, eliminating PCB redesign requirements
• Current Rating: The IR42-21C/TR8 supports 65mA maximum forward current, exceeding the GL100MN1MP1 specification of 50mA, providing operational margin
• Thermal Range: The IR42-21C/TR8 operating range (-25°C ~ 85°C) covers the majority of the GL100MN1MP1 range (-30°C ~ 85°C), with the lower temperature limit difference of 5°C applicable only in extreme cold environments

Frequently Asked Questions (FAQ)

Q: Can the IR42-21C/TR8 directly replace the GL100MN1MP1 without circuit modifications?

A: Yes. Both components share identical forward voltage (1.2V), wavelength (940nm), package type (2-SMD, No Lead), and mounting method (Surface Mount). No circuit redesign is required for substitution.

Q: What is the significance of the 65mA vs. 50mA current rating difference?

A: The IR42-21C/TR8 supports higher maximum forward current (65mA) compared to the GL100MN1MP1 (50mA). This provides additional operational margin and does not create compatibility issues when the circuit is designed for 50mA operation.

Q: How does the 30° viewing angle of the IR42-21C/TR8 compare to the 20° angle of the GL100MN1MP1?

A: The IR42-21C/TR8 has a wider viewing angle (30° vs. 20°), which increases the optical detection range. This is generally beneficial for proximity sensing and IR communication applications and does not create incompatibility.

Q: Are there temperature range considerations for substitution?

A: The IR42-21C/TR8 operates from -25°C to 85°C, while the GL100MN1MP1 operates from -30°C to 85°C. The 5°C difference at the lower limit is relevant only for applications requiring operation below -25°C. For standard industrial and consumer applications, this difference is not significant.

Q: What packaging format is the IR42-21C/TR8 supplied in?

A: The IR42-21C/TR8 is supplied in Tape & Reel (TR) format, standard for high-volume surface mount assembly. The GL100MN1MP1 packaging format was not specified in the available data.

Q: Are both components RoHS compliant?

A: Yes. The GL100MN1MP1 is RoHS Compliant, and the IR42-21C/TR8 is ROHS3 Compliant. Both meet regulatory requirements for hazardous substance restrictions.
