OD-880L Infrared Emitter - Equivalent & Substitute Parts

Part Overview

The OD-880L is an infrared (IR) emitter manufactured by Opto Diode Corp, designed for applications requiring 880nm wavelength emission at 100mA forward current. This component operates at a typical forward voltage of 1.55V and delivers 50mW/sr radiant intensity in a TO-46-2 lens top metal can package with a 35° viewing angle.

The OD-880L is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where 880nm IR emission specifications are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OD-880L is determined by the following critical parameters:

Wavelength Compatibility: The primary substitution criterion is wavelength. The OD-880L operates at 880nm. Substitute parts must maintain the same wavelength to preserve optical system performance and spectral response characteristics.

Electrical Parameters: Forward current (If) and forward voltage (Vf) must be compatible with existing circuit designs. The OD-880L operates at 100mA maximum forward current and 1.55V typical forward voltage.

Mechanical Compatibility: Package type (TO-46-2), mounting method (Through Hole), and orientation (Top View) must match to ensure physical fit within existing PCB layouts and mechanical assemblies.

Optical Parameters: Viewing angle (35°) and radiant intensity specifications determine the optical performance envelope for the application.

Based on these criteria, the OD-850L is identified as a substitute part. However, the OD-850L operates at 850nm wavelength, which differs from the OD-880L specification. This represents a wavelength shift and is not a direct equivalent for applications requiring strict 880nm operation.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The OD-880L is obsolete, while the OD-850L is active and currently in production. The OD-850L has 1908 units in stock, ensuring availability for immediate procurement.

Compliance and Certifications: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The OD-850L carries RoHS Compliant status. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints.

Electrical Compatibility: Forward current specifications are identical at 100mA maximum. Forward voltage differs by 0.05V (1.55V vs. 1.6V), which is within typical circuit tolerance margins for most applications.

Thermal Operating Range: The OD-880L operates from -55°C to 100°C, while the OD-850L operates from -40°C to 100°C. Applications requiring operation below -40°C cannot use the OD-850L as a substitute.

Wavelength Consideration: The OD-850L operates at 850nm instead of 880nm. This wavelength difference affects optical system performance and spectral response. Selection of the OD-850L is appropriate only for applications where 850nm wavelength is acceptable or where the optical system can accommodate the spectral shift.

Frequently Asked Questions (FAQ)

Q: Can the OD-850L directly replace the OD-880L in all applications?

A: No. While both parts share identical package, mounting type, viewing angle, and forward current specifications, the OD-850L operates at 850nm wavelength versus the OD-880L's 880nm. Direct substitution is only appropriate for applications where 850nm wavelength is acceptable or where the optical system design permits wavelength variation.

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

A: The OD-880L has a typical forward voltage of 1.55V, while the OD-850L is 1.6V. The 0.05V difference is typically accommodated by standard circuit designs with adequate voltage headroom.

Q: Are there thermal operating range differences?

A: Yes. The OD-880L operates from -55°C to 100°C, while the OD-850L operates from -40°C to 100°C. Applications requiring operation below -40°C ambient temperature cannot use the OD-850L as a substitute.

Q: Are both parts in the same package?

A: Yes. Both the OD-880L and OD-850L use the TO-46-2 Lens Top Metal Can package with Through Hole mounting and Top View orientation. Physical fit within existing PCB layouts is identical.

Q: What is the availability status of these parts?

A: The OD-880L is obsolete with 633 units in stock. The OD-850L is active with 1908 units in stock, providing better long-term availability for new designs and production runs.

Q: Do both parts have the same compliance certifications?

A: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The OD-850L carries RoHS Compliant status. Both have Moisture Sensitivity Level 1 (Unlimited).
