Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTSM0013-199-IR is determined by the following critical parameters:

• Wavelength: Must remain 1300nm for optical system compatibility
• Package / Case: Must be 1206 (3216 Metric) for PCB layout compatibility
• Mounting Type: Must be Surface Mount for assembly process compatibility
• Current - DC Forward (If) (Max): Must be 50mA or greater to support existing circuit design
• Operating Temperature Range: Must encompass -40°C ~ 85°C minimum
• RoHS Compliance: Must maintain RoHS Compliant status for regulatory requirements

The MTSM0013-194-IR qualifies as a direct substitute based on these parameters. Variations in forward voltage (Vf) and viewing angle are permissible within circuit design tolerances when the primary optical and electrical characteristics remain compatible.

Parameter Comparison

Engineering Selection Recommendations

The MTSM0013-194-IR is the qualified substitute for the obsolete MTSM0013-199-IR. Both parts are manufactured by Marktech Optoelectronics and maintain identical wavelength (1300nm), package form factor (1206), mounting type (Surface Mount), and maximum forward current (50mA) specifications. The substitute part carries Active product status, ensuring continued availability and supply chain reliability.

The MTSM0013-194-IR exhibits a forward voltage increase of 0.1V (1.1V versus 1V) and a reduced viewing angle (40° versus 90°). These parameter variations require circuit-level evaluation to confirm compatibility with existing power supply design and optical beam pattern requirements. The identical operating temperature range (-40°C ~ 85°C) and RoHS compliance status support direct substitution from regulatory and environmental perspectives.

Frequently Asked Questions (FAQ)

Q: Can MTSM0013-194-IR directly replace MTSM0013-199-IR without circuit modification?

A: Direct replacement is possible if the circuit design accommodates the 0.1V higher forward voltage and the 40° viewing angle meets optical system requirements. The identical 50mA maximum current rating and 1206 package ensure mechanical and electrical interface compatibility.

Q: What is the significance of the viewing angle difference between these parts?

A: The MTSM0013-199-IR provides a 90° viewing angle (wider beam pattern), while the MTSM0013-194-IR provides a 40° viewing angle (narrower, more directional beam). Application-specific optical design determines which viewing angle is appropriate. Narrower viewing angles concentrate radiant intensity in a specific direction.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -40°C ~ 85°C, supporting equivalent thermal performance in the same application environments.

Q: What is the impact of the 0.1V forward voltage difference?

A: The MTSM0013-194-IR requires 1.1V versus 1V for the original part. Power supply design and current-limiting circuit configuration must accommodate this voltage increase. Verify that existing series resistor values and supply voltage remain appropriate for the substitute part.

Q: Why is the substitute part listed as Active while the original is Obsolete?

A: The MTSM0013-194-IR maintains Active product status, indicating ongoing manufacturing and availability from Marktech Optoelectronics. This ensures long-term supply chain continuity for new designs and production runs.

Q: Are packaging and moisture sensitivity specifications identical?

A: Yes. Both parts use 1206 (3216 Metric) Surface Mount package with identical Moisture Sensitivity Level (MSL) rating of 5A (24 Hours), requiring equivalent handling and storage protocols.
