Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSM0013-843-IR is determined by the following critical parameters:

Core Compatibility Criteria:

• Wavelength: 1300nm (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Current - DC Forward (If) (Max): 50mA (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Typ): Tolerance within typical operating specifications
• Viewing Angle: Variation acceptable based on application requirements
• Product Status: Active status preferred for new designs; Obsolete status acceptable for legacy support
• Packaging Format: Tape & Reel (TR) acceptable as alternative to standard packaging

The MTSM0013-844-IR qualifies as a direct substitute based on matching all core compatibility criteria while maintaining identical wavelength, package format, current rating, and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

The MTSM0013-844-IR is the designated substitute for the obsolete MTSM0013-843-IR. Both components maintain identical wavelength (1300nm), package format (1206 / 3216 Metric), maximum forward current (50mA), and operating temperature range (-40°C ~ 85°C). The MTSM0013-844-IR carries Active product status, ensuring continued availability and manufacturing support.

Differences between the main part and substitute are limited to forward voltage (0.9V vs. 1.1V) and viewing angle (50° vs. 40°). These variations fall within acceptable parameters for SWIR emitter applications and do not compromise core functional compatibility.

Both parts maintain identical RoHS Compliance and Moisture Sensitivity Level (MSL) ratings, ensuring equivalent environmental and regulatory compliance. The MTSM0013-844-IR is available in Tape & Reel (TR) packaging format, standard for high-volume surface mount assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the MTSM0013-844-IR directly replace the MTSM0013-843-IR in existing designs?

A: Yes. Both parts share identical wavelength (1300nm), package format (1206 / 3216 Metric), maximum forward current (50mA), and operating temperature specifications (-40°C ~ 85°C). The forward voltage difference (0.9V vs. 1.1V) and viewing angle variation (50° vs. 40°) are within acceptable substitution parameters for SWIR emitter applications.

Q: What is the significance of the Product Status difference?

A: The MTSM0013-843-IR is classified as Obsolete, indicating discontinued manufacturing and limited inventory availability. The MTSM0013-844-IR maintains Active status, ensuring ongoing production, supply chain availability, and manufacturer support for new designs and legacy system maintenance.

Q: Are there packaging format considerations for substitution?

A: The MTSM0013-843-IR is supplied in standard packaging, while the MTSM0013-844-IR is available in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated surface mount assembly operations and does not affect component functionality or electrical performance.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the MTSM0013-843-IR and MTSM0013-844-IR are RoHS Compliant and share identical Moisture Sensitivity Level (MSL) ratings of 5A (24 Hours), ensuring equivalent environmental and regulatory compliance across applications.

Q: How do the forward voltage and viewing angle differences affect substitution?

A: The forward voltage increase from 0.9V to 1.1V and viewing angle reduction from 50° to 40° are design variations within the MTSM0013 series. These parameters do not affect wavelength accuracy or maximum current handling. Circuit designs must account for the forward voltage difference in current-limiting resistor calculations. The narrower viewing angle (40°) provides more focused infrared emission compared to the wider 50° angle of the original part.
