OD-880W Infrared Emitter - Equivalent & Substitute Parts

Part Overview

The OD-880W is an infrared (IR) emitter operating at 880nm wavelength, designed for through-hole mounting in TO-46-2 metal can packaging. This component delivers 100mA forward current with 16mW/sr radiant intensity and operates across -55°C to 100°C. The OD-880W is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OD-880W is determined by the following critical parameters:

Primary Compatibility Criteria:

• Wavelength specification (880nm primary requirement)
• Maximum forward current rating (100mA)
• Package type (TO-46-2 metal can)
• Mounting configuration (through-hole)
• Viewing angle (80°)

Secondary Compatibility Factors:

• Forward voltage tolerance (Vf range)
• Operating temperature range (minimum -55°C requirement)
• Radiant intensity performance
• Moisture sensitivity classification

The OD-850W is identified as a substitute part. While it operates at a different wavelength (850nm instead of 880nm), it maintains electrical and mechanical compatibility across current rating, package type, mounting method, and viewing angle. The wavelength difference represents a functional variation that may be acceptable depending on application-specific spectral requirements.

Engineering Selection Recommendations

OD-880W Status: Obsolete product with 970 units in current inventory.

OD-850W Recommendation: Active product with 24,412 units in inventory. Suitable for applications where 850nm wavelength operation is acceptable. The OD-850W maintains electrical compatibility (100mA current, similar forward voltage) and mechanical compatibility (TO-46-2 package, through-hole mounting, 80° viewing angle). The OD-850W is RoHS Compliant, providing regulatory advantage over the obsolete OD-880W.

Temperature Consideration: The OD-850W operating range (-40°C to 100°C) is narrower than the OD-880W (-55°C to 100°C). Applications requiring operation below -40°C require verification of OD-850W suitability or identification of alternative components.

Packaging Variation: The OD-850W features a lens top configuration compared to the OD-880W metal can design. This optical difference may affect beam characteristics and should be evaluated for specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the OD-850W directly replace the OD-880W in existing designs?

A: Mechanical and electrical compatibility exists (identical current rating, package type, mounting method, viewing angle). However, the wavelength difference (850nm vs. 880nm) requires application-level verification. Systems designed specifically for 880nm spectral response may require optical or detection circuit adjustments.

Q: What is the forward voltage difference between these parts?

A: The OD-880W specifies 1.55V typical forward voltage; the OD-850W specifies 1.6V typical. The 0.05V variance is within standard component tolerance and does not typically require circuit redesign.

Q: Does the OD-850W lens top configuration affect compatibility?

A: The lens top design on the OD-850W may alter optical beam characteristics compared to the OD-880W metal can design. Physical mounting compatibility remains unchanged (TO-46-2 through-hole package), but optical performance should be validated for applications sensitive to beam profile or intensity distribution.

Q: Are there temperature range limitations with the OD-850W?

A: The OD-850W operates from -40°C to 100°C, compared to the OD-880W range of -55°C to 100°C. Applications requiring operation below -40°C cannot use the OD-850W as a direct substitute without additional thermal management or alternative component selection.

Q: What is the inventory status for these parts?

A: The OD-880W (obsolete) has 970 units available. The OD-850W (active product) has 24,412 units in stock, providing superior long-term availability and supply chain reliability.

Q: Is the OD-850W RoHS compliant?

A: Yes, the OD-850W is RoHS Compliant. The OD-880W RoHS status is not specified in available documentation.
