Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTSM0012-199-IR is determined by the following critical parameters:

• Wavelength: Must remain 1200nm for optical system compatibility
• Package / Case: Must be 1206 (3216 Metric) for PCB layout and mechanical fit
• Mounting Type: Must be Surface Mount for assembly process compatibility
• Current Rating (If): Maximum 50mA forward current capability
• Operating Temperature Range: Must support -40°C ~ 85°C
• Manufacturer: Marktech Optoelectronics maintains design continuity

The MTSM0012-194-IR qualifies as a direct substitute based on matching wavelength, package, mounting type, current rating, and operating temperature specifications. This substitute is an Active product with improved availability compared to the Obsolete MTSM0012-199-IR.

Parameter Comparison

Engineering Selection Recommendations

The MTSM0012-194-IR is the qualified substitute for the obsolete MTSM0012-199-IR. Both components share identical wavelength (1200nm), current rating (50mA), package format (1206), and operating temperature range (-40°C ~ 85°C). Both maintain RoHS Compliance and identical export classification (EAR99).

The MTSM0012-194-IR is currently Active with confirmed inventory availability (1145 Pcs), whereas the MTSM0012-199-IR is Obsolete. The substitute exhibits a forward voltage of 1.1V compared to 1V in the original part, and provides a wider viewing angle of 120° versus 90°. These parameter variations remain within acceptable substitution tolerances for SWIR emitter applications in the 1200nm spectrum.

Frequently Asked Questions (FAQ)

Q: Can MTSM0012-194-IR directly replace MTSM0012-199-IR in existing designs?

A: Yes. Both parts share identical wavelength (1200nm), current rating (50mA), package format (1206), and operating temperature specifications (-40°C ~ 85°C). The substitute is mechanically and electrically compatible for PCB assembly and circuit operation.

Q: What are the differences between these two parts?

A: The primary differences are forward voltage (1.1V vs 1V) and viewing angle (120° vs 90°). The MTSM0012-194-IR also includes specified radiant intensity (2.1mW/sr @ 50mA) and is supplied in Tape & Reel packaging. The substitute is an Active product with current manufacturing support.

Q: Are both parts RoHS compliant?

A: Yes. Both MTSM0012-199-IR and MTSM0012-194-IR are RoHS Compliant with identical Moisture Sensitivity Level (5A, 24 Hours) and export classification (EAR99).

Q: What is the package format for these components?

A: Both parts use the 1206 (3216 Metric) Surface Mount package format, ensuring identical PCB footprint and assembly compatibility.

Q: Why is the original part listed as Obsolete?

A: The MTSM0012-199-IR is classified as Obsolete, indicating discontinued manufacturing. The MTSM0012-194-IR is the active equivalent maintained by Marktech Optoelectronics for continued supply and support.
