Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSM0012-843-IR is determined by strict alignment of the following electrical and mechanical parameters:

• Wavelength: Must be 1200nm (primary functional requirement)
• Maximum Forward Current (If): Must support 50mA operation
• Package / Case: Must be 1206 (3216 Metric) for PCB layout compatibility
• Mounting Type: Must be Surface Mount for assembly process compatibility
• Operating Temperature Range: Must encompass -40°C ~ 85°C
• RoHS Compliance: Must maintain RoHS Compliant status

The MTSM0012-844-IR meets all substitution criteria. While it exhibits a higher typical forward voltage (1.1V vs. 1V) and narrower viewing angle (40° vs. 50°), these variations remain within acceptable tolerance for equivalent component classification and do not preclude functional substitution in circuit designs rated for the specified parameters.

Engineering Selection Recommendations

The MTSM0012-844-IR is the qualified equivalent for MTSM0012-843-IR applications. Selection rationale:

• Product Status: MTSM0012-844-IR maintains Active status, ensuring continued manufacturing availability and supply chain reliability, whereas MTSM0012-843-IR is Obsolete.
• Compliance Alignment: Both components maintain identical RoHS Compliance, ECCN (EAR99), and HTSUS classifications, ensuring regulatory and export control consistency.
• Electrical Compatibility: Identical maximum forward current (50mA) and operating temperature range (-40°C ~ 85°C) confirm functional equivalence for circuit-level integration.
• Mechanical Compatibility: Identical 1206 (3216 Metric) package and Surface Mount configuration ensure direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can MTSM0012-844-IR be used as a direct replacement for MTSM0012-843-IR?

A: Yes. Both components share identical wavelength (1200nm), maximum forward current (50mA), package form factor (1206), mounting type (Surface Mount), and operating temperature range (-40°C ~ 85°C). The MTSM0012-844-IR is the active equivalent.

Q: What are the differences between these two parts?

A: The MTSM0012-844-IR exhibits a higher typical forward voltage (1.1V vs. 1V) and a narrower viewing angle (40° vs. 50°). These differences do not affect substitution eligibility for applications designed to the specified electrical and optical parameters.

Q: Why is MTSM0012-843-IR marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. The MTSM0012-844-IR represents the current active production equivalent, ensuring supply continuity for new designs and legacy system support.

Q: Are there packaging differences between these parts?

A: Both components are supplied in 1206 (3216 Metric) Surface Mount packages with identical Moisture Sensitivity Level (5A, 24 Hours). Packaging compatibility is confirmed.

Q: Do these parts have the same regulatory certifications?

A: Yes. Both components are RoHS Compliant and share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming regulatory and export control equivalence.
