Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5IRC-940-F is determined by the following critical parameters:

Primary Matching Criteria:

• Wavelength: 940nm (exact match required)
• Package / Case: Radial through-hole (mechanical compatibility)
• Mounting Type: Through Hole (board-level compatibility)
• Orientation: Top View (optical axis alignment)

Secondary Compatibility Parameters:

• Current - DC Forward (If) Max: Substitute must support the design current requirement
• Voltage - Forward (Vf) Typical: Circuit voltage compatibility
• Viewing Angle: Application-dependent; narrow angles (15°–16°) are functionally equivalent
• Operating Temperature Range: Substitute range must encompass or exceed the application requirement
• Radiant Intensity (Ie): Optical output performance; specifications use different measurement units (mW/cm² vs. mW/sr) and test conditions

The LTE-209 from Lite-On Inc. meets all primary matching criteria and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

LTE-209 Substitution Suitability:

The LTE-209 is a direct mechanical and optical substitute for the 5IRC-940-F. Both components share identical wavelength (940nm), package type (radial through-hole), and orientation (top view). The LTE-209 is currently in active production with confirmed inventory availability (1619 pcs), whereas the 5IRC-940-F is obsolete.

Electrical Parameter Differences:

The LTE-209 exhibits a lower typical forward voltage (1.2V vs. 1.4V) and supports a higher maximum forward current (60mA vs. 50mA). The operating temperature range of the LTE-209 (-40°C to 85°C) is narrower at the lower bound compared to the 5IRC-940-F (-45°C to 85°C). Both components carry MSL 1 (Unlimited) moisture sensitivity classification.

Compliance and Certification:

The LTE-209 is RoHS3 compliant. Both components are classified under ECCN EAR99 and HTSUS 8541.41.0000. The LTE-209's active product status ensures ongoing technical support and supply chain continuity.

Selection Basis:

Component selection should be based on circuit voltage tolerance, forward current requirements, and minimum operating temperature specification. The LTE-209 is suitable for applications where the lower forward voltage and higher current rating do not conflict with circuit design parameters, and where the -40°C minimum operating temperature meets application requirements.

Frequently Asked Questions (FAQ)

Q: Can the LTE-209 be used as a direct replacement for the 5IRC-940-F in existing designs?

A: The LTE-209 is mechanically and optically compatible with the 5IRC-940-F due to matching wavelength (940nm), radial through-hole package, and top-view orientation. Circuit-level compatibility depends on whether the design can accommodate the LTE-209's lower forward voltage (1.2V vs. 1.4V) and higher maximum current rating (60mA vs. 50mA). The narrower operating temperature range (-40°C to 85°C vs. -45°C to 85°C) must also be verified against application requirements.

Q: What are the key differences in radiant intensity between these components?

A: The 5IRC-940-F specifies 7.0mW/cm² at 100mA, while the LTE-209 specifies 1.38mW/sr at 20mA. These measurements use different units (mW/cm² vs. mW/sr) and different test currents, making direct numerical comparison invalid. Radiant intensity performance must be evaluated based on the specific application's optical requirements and measurement methodology.

Q: Why is the LTE-209 preferred over the 5IRC-940-F?

A: The LTE-209 is an active product with current manufacturing support and confirmed inventory availability, whereas the 5IRC-940-F is obsolete. For new designs or ongoing production, the LTE-209 provides supply chain continuity and technical support from Lite-On Inc.

Q: Are there any moisture sensitivity or environmental compliance concerns?

A: Both components carry identical MSL 1 (Unlimited) moisture sensitivity classification, indicating no special moisture handling requirements. Both are classified under ECCN EAR99 and HTSUS 8541.41.0000. The LTE-209 is RoHS3 compliant, supporting environmental regulatory requirements.

Q: What should be verified before implementing the LTE-209 as a substitute?

A: Verification should include circuit voltage compatibility with the LTE-209's 1.2V typical forward voltage, confirmation that the design current requirement does not exceed 60mA, and validation that the -40°C minimum operating temperature meets application specifications. Optical performance should be evaluated based on the specific measurement methodology and application requirements.
