OD-880WHT Infrared Emitter - Equivalent & Substitute Parts

Part Overview

The OD-880WHT is an infrared (IR) emitter manufactured by Opto Diode Corp, designed for applications requiring 880nm wavelength emission at 100mA forward current. This component features a TO-46-2 metal can package with a 80° viewing angle and operates across a temperature range of -65°C to 150°C.

The OD-880WHT is classified as obsolete. Identifying suitable substitute components is necessary for design continuity, procurement planning, and system integration in applications where this emitter is currently specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OD-880WHT is evaluated based on the following critical parameters that define functional compatibility:

Primary Compatibility Criteria:

• Package Type: Both main and substitute parts must use TO-46-2 metal can through-hole mounting to ensure mechanical and thermal compatibility
• Maximum Forward Current (If): Substitute parts must support the same 100mA maximum current rating
• Operating Temperature Range: Substitute parts must maintain the -65°C to 150°C operating window
• Wavelength: While the OD-880WHT operates at 880nm, substitute parts may operate at adjacent wavelengths within the near-infrared spectrum if the application permits wavelength variation

Secondary Considerations:

• Forward voltage (Vf) variations are acceptable within typical circuit design tolerances
• Viewing angle differences are acceptable provided the substitute part's angle meets or exceeds application requirements
• Product status (active vs. obsolete) affects long-term availability and supply chain planning

The OD-850WHT qualifies as a substitute based on matching package type, forward current rating, and operating temperature range, despite operating at a different wavelength (850nm vs. 880nm).

Parameter Comparison

Engineering Selection Recommendations

OD-850WHT as Substitute for OD-880WHT:

The OD-850WHT is an active product with current manufacturing support, addressing the obsolescence status of the OD-880WHT. Both components share identical maximum forward current (100mA), operating temperature range (-65°C to 150°C), and through-hole TO-46-2 package configuration.

The primary difference is wavelength: OD-850WHT operates at 850nm compared to the OD-880WHT's 880nm. This 30nm difference falls within the near-infrared spectrum and is suitable for applications where wavelength-specific performance is not a critical design constraint.

The OD-850WHT provides a wider viewing angle (160° vs. 80°), which may be advantageous for applications requiring broader light distribution. Forward voltage is nominally equivalent (1.6V vs. 1.55V), representing a negligible difference in circuit operation.

Both components carry identical ECCN (EAR99) and HTSUS classifications, and both maintain MSL 1 (Unlimited) moisture sensitivity ratings. The OD-850WHT's RoHS Compliant status provides additional regulatory alignment for modern manufacturing environments.

Frequently Asked Questions (FAQ)

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

A: Direct replacement is possible from a mechanical and electrical standpoint. Both components use identical TO-46-2 through-hole packages, support 100mA forward current, and operate across -65°C to 150°C. However, the 30nm wavelength difference (850nm vs. 880nm) must be evaluated against application-specific requirements. Applications sensitive to wavelength performance should conduct functional testing.

Q: What is the significance of the viewing angle difference between these parts?

A: The OD-880WHT provides an 80° viewing angle, while the OD-850WHT provides 160°. A wider viewing angle results in broader light distribution but lower peak intensity in the forward direction. Applications requiring narrow-beam emission may experience performance changes with the substitute part.

Q: Why is the OD-880WHT classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The OD-850WHT, classified as active, represents the current product line alternative from Opto Diode Corp for near-infrared emitter applications in the 100mA TO-46-2 package category.

Q: Are there compliance or regulatory differences between these parts?

A: Both components share identical ECCN (EAR99) and HTSUS classifications. The OD-850WHT carries RoHS Compliant certification, which may be required for certain manufacturing environments. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What inventory considerations apply to these parts?

A: The OD-880WHT has 720 pieces in stock but is obsolete with no future production. The OD-850WHT has 13,473 pieces in stock and is an active product with ongoing availability. For new designs or long-term production planning, the OD-850WHT provides supply chain continuity.

Q: How do forward voltage differences affect circuit design?

A: The OD-850WHT operates at 1.6V typical forward voltage compared to the OD-880WHT's 1.55V. This 0.05V difference is within standard circuit design tolerances and does not require significant modifications to existing driver circuits or current-limiting resistor calculations.
