MTSM5015-843-IR Equivalent & Substitute Parts

Part Overview

The MTSM5015-843-IR is a Surface Mount infrared (IR) emitter operating at 1550nm wavelength, designed for SWIR (Short-Wave Infrared) applications. This component is classified as Obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The part operates at 0.75V forward voltage with a maximum forward current of 50mA and features a 55° viewing angle in a compact 1206 (3216 Metric) SMD package.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSM5015-843-IR is determined by the following critical parameters:

• Wavelength: Must be 1550nm (SWIR band requirement)
• Package/Case: Must be 1206 (3216 Metric) for PCB footprint compatibility
• Mounting Type: Must be Surface Mount for assembly process compatibility
• Forward Current Rating: Must support 50mA maximum
• Operating Temperature Range: Must cover -40°C to 85°C minimum
• RoHS Compliance: Must maintain RoHS Compliant status

The MTSM5015-844-IR qualifies as a direct substitute based on these parameters. Both components share identical wavelength, package, mounting type, current rating, temperature range, and RoHS compliance. Variations in forward voltage (0.75V vs. 1.05V) and viewing angle (55° vs. 40°) represent acceptable design trade-offs within the same product family.

Parameter Comparison

Engineering Selection Recommendations

The MTSM5015-844-IR is the qualified substitute for the obsolete MTSM5015-843-IR. Both components maintain identical compliance certifications (RoHS Compliant, ECCN: EAR99, HTSUS: 8541.41.0000) and share the same critical electrical and mechanical specifications required for 1550nm SWIR emitter applications.

The primary distinction is product status: MTSM5015-844-IR is Active with current manufacturing availability, while MTSM5015-843-IR is Obsolete. The forward voltage differential (0.30V) and viewing angle reduction (15°) are design variations within the same product family and do not preclude functional substitution when circuit design accommodates these parameters.

Frequently Asked Questions (FAQ)

Q: Can MTSM5015-844-IR directly replace MTSM5015-843-IR in existing designs?

A: Yes, provided the circuit design accommodates the higher forward voltage (1.05V vs. 0.75V) and narrower viewing angle (40° vs. 55°). Both components share identical wavelength, package, current rating, and temperature specifications.

Q: What is the impact of the 0.30V forward voltage difference?

A: The higher forward voltage of MTSM5015-844-IR requires circuit adjustment to the current-limiting resistor or power supply configuration. This is a standard design consideration and does not affect optical or thermal performance.

Q: Does the 15° viewing angle reduction affect system performance?

A: The narrower 40° viewing angle of MTSM5015-844-IR concentrates optical output over a smaller solid angle. System compatibility depends on the receiver's field of view and optical coupling design. Verify alignment requirements for your specific application.

Q: Are both parts RoHS compliant?

A: Yes, both MTSM5015-843-IR and MTSM5015-844-IR are RoHS Compliant with identical moisture sensitivity levels (5A, 24 Hours).

Q: What is the availability status of these parts?

A: MTSM5015-843-IR is Obsolete with limited inventory (791 Pcs). MTSM5015-844-IR is Active with current manufacturing support and available inventory (608 Pcs).
