Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTSM5014-843-IR is determined by the following critical parameters:

• Wavelength compatibility: SWIR emitters in the 1450nm–1460nm range are functionally interchangeable for most optical sensing and communication applications
• Maximum forward current: Both parts support 50mA operation
• Package and mounting: Identical 1206 (3216 Metric) surface mount package ensures PCB compatibility
• Operating temperature range: Both parts operate across -40°C to 85°C
• Forward voltage tolerance: Typical forward voltages of 1V and 1.05V are within acceptable design margins for standard driver circuits
• Viewing angle variation: The substitute part features a 40° viewing angle compared to the original 30°, which represents an expanded field of view suitable for broader optical coverage

The MTSM6014-844-IR qualifies as a direct substitute based on these aligned electrical and mechanical parameters.

Engineering Selection Recommendations

The MTSM6014-844-IR is the qualified substitute for the obsolete MTSM5014-843-IR. Selection is supported by the following factors:

• Product status alignment: The substitute part carries Active status, ensuring long-term availability and supply chain continuity
• Regulatory compliance: Both parts maintain RoHS Compliant certification and identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications
• Electrical compatibility: Identical maximum forward current (50mA) and operating temperature range (-40°C to 85°C) ensure direct circuit compatibility
• Mechanical compatibility: Identical 1206 (3216 Metric) surface mount package and MSL rating (5A, 24 Hours) permit direct PCB placement without redesign
• Wavelength proximity: The 10nm wavelength difference (1450nm to 1460nm) falls within the SWIR spectrum and is suitable for optical applications requiring this spectral range
• Enhanced optical coverage: The increased viewing angle (40° versus 30°) provides expanded field of view, beneficial for applications requiring broader optical detection or emission patterns

Frequently Asked Questions (FAQ)

Q: Can the MTSM6014-844-IR be used as a direct drop-in replacement for the MTSM5014-843-IR?

A: Yes. Both parts share identical package specifications (1206 / 3216 Metric), mounting type (Surface Mount), maximum forward current (50mA), and operating temperature range (-40°C to 85°C). PCB layout and electrical connections require no modification.

Q: What is the significance of the 10nm wavelength difference between 1450nm and 1460nm?

A: Both wavelengths operate within the short-wave infrared (SWIR) spectrum. The 10nm difference is negligible for most optical sensing, communication, and spectroscopic applications. System performance depends on the specific application's wavelength tolerance, which should be verified against design requirements.

Q: How does the viewing angle change from 30° to 40° affect system performance?

A: The increased viewing angle (40° versus 30°) expands the optical field of view. This benefits applications requiring broader coverage but may reduce peak radiant intensity in the central axis. Applications with strict directional requirements should confirm that the wider angle aligns with optical system design.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both parts are RoHS Compliant and share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. Moisture Sensitivity Level (MSL) ratings are identical at 5A (24 Hours).

Q: What is the forward voltage difference, and does it affect circuit design?

A: The forward voltage difference is 0.05V (1V typical for MTSM5014-843-IR versus 1.05V typical for MTSM6014-844-IR). This 5% variation is within standard design margins for IR emitter driver circuits and does not require circuit modification.

Q: Why is the original part listed as obsolete?

A: Obsolescence typically reflects manufacturer discontinuation due to market demand, product line consolidation, or transition to newer designs. The MTSM6014-844-IR represents the active equivalent within Marktech Optoelectronics' current product portfolio.
