MTSM5015-199-IR Equivalent & Substitute Parts

Part Overview

The MTSM5015-199-IR is a Surface Mount Infrared (IR) Emitter operating at 1550nm wavelength, designed for SWIR (Short-Wave Infrared) applications. Manufactured by Marktech Optoelectronics in a 1206 (3216 Metric) package, this component is rated for 50mA DC forward current with a 1V typical forward voltage and 90° viewing angle. The part is currently listed as Obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSM5015-199-IR is determined by the following critical parameters:

• Wavelength: 1550nm (exact match required for SWIR application compatibility)
• Current Rating: 50mA maximum DC forward current (electrical compatibility)
• Package / Case: 1206 (3216 Metric) (mechanical and PCB layout compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)
• Operating Temperature Range: -40°C ~ 85°C (thermal environment compatibility)

The MTSM5015-194-IR meets all substitution criteria. While it exhibits a slightly higher forward voltage (1.05V vs. 1V) and wider viewing angle (120° vs. 90°), these variations remain within acceptable operational parameters for equivalent functionality. Both components share identical wavelength, current rating, package specification, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The MTSM5015-194-IR is the qualified substitute for the obsolete MTSM5015-199-IR. Both components are manufactured by Marktech Optoelectronics and maintain RoHS compliance and identical MSL ratings. The substitute part carries Active product status, ensuring continued availability and supply chain reliability.

The MTSM5015-194-IR is available in Tape & Reel (TR) packaging with 2565 units in current inventory, compared to the main part's 700 units. For new designs or procurement requiring the 1550nm SWIR emitter in 1206 package format, the MTSM5015-194-IR provides equivalent electrical and mechanical compatibility with the added advantage of active product support.

Frequently Asked Questions (FAQ)

Q: Can the MTSM5015-194-IR directly replace the MTSM5015-199-IR in existing designs?

A: Yes. Both components share identical wavelength (1550nm), current rating (50mA), package specification (1206), and operating temperature range (-40°C ~ 85°C). The forward voltage difference (1.05V vs. 1V) and viewing angle variation (120° vs. 90°) do not prevent functional substitution in standard SWIR emitter applications.

Q: What is the significance of the viewing angle difference?

A: The MTSM5015-194-IR provides a wider 120° viewing angle compared to the 90° angle of the main part. This represents an expanded radiation pattern and does not restrict compatibility; designs accommodating 90° can operate with 120° without modification.

Q: Why is the main part listed as Obsolete?

A: Obsolete status indicates the MTSM5015-199-IR is no longer in active production. The MTSM5015-194-IR, with Active status, represents the current manufacturing equivalent from Marktech Optoelectronics.

Q: Are packaging options different between these parts?

A: The main part is specified with standard packaging, while the substitute is available in Tape & Reel (TR) format. Both use the identical 1206 (3216 Metric) package case. TR packaging is standard for high-volume surface mount assembly processes.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both components are RoHS Compliant with identical Moisture Sensitivity Level (MSL) ratings of 5A (24 Hours), ECCN classification (EAR99), and HTSUS code (8541.41.0000).
