OP295B Infrared Emitter 890nm - Equivalent & Substitute Parts

Part Overview

The OP295B is an infrared (IR) emitter manufactured by TT Electronics/Optek Technology, designed for applications requiring 890nm wavelength emission at 150mA forward current. This through-hole T 1 3/4 package component operates across -40°C to 100°C and maintains active product status with full RoHS3 compliance. Substitute parts become necessary when addressing supply constraints, package form factor requirements, or wavelength optimization for specific detector compatibility in infrared sensing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OP295B is determined by the following critical parameters: infrared emitter type classification, wavelength range (880nm-940nm acceptable for most IR detector applications), viewing angle (20° standard), through-hole mounting compatibility, and RoHS3 compliance status. The substitute parts are grouped into two categories based on package form factor:

Category 1: T 1 3/4 Through-Hole Package (Direct Package Match)

• LTE-4208 (LITEON): 940nm wavelength, 50mA maximum current, 1.2V forward voltage

Category 2: Radial Through-Hole Package (Alternative Form Factor)

• XTHI12BF and XTHI12W (SunLED): 880nm wavelength, 50mA maximum current, 1.3V forward voltage
• XTNI12BF and XTNI12W (SunLED): 940nm wavelength, 50mA maximum current, 1.2V forward voltage

All substitute parts maintain 20° viewing angle, through-hole mounting, RoHS3 compliance, and operate within -40°C to 85°C temperature range.

Engineering Selection Recommendations

For T 1 3/4 Package Continuity: LTE-4208 provides direct package compatibility with the OP295B. This LITEON component maintains identical through-hole T 1 3/4 form factor and 20° viewing angle. Selection of LTE-4208 requires circuit design accommodation for reduced maximum forward current (50mA versus 150mA) and lower forward voltage (1.2V versus 4V). Wavelength shift from 890nm to 940nm is acceptable where detector spectral response encompasses both wavelengths.

For Radial Package Applications: XTHI12BF, XTHI12W, XTNI12BF, and XTNI12W offer radial through-hole mounting alternatives. These SunLED components are suitable for designs where radial orientation provides mechanical or thermal advantages. All four parts maintain active product status and RoHS3 compliance. Selection between 880nm (XTHI series) and 940nm (XTNI series) depends on detector spectral matching requirements.

Compliance and Availability: All substitute parts carry RoHS3 compliance, REACH unaffected status, and EAR99 ECCN classification matching the OP295B. Inventory availability ranges from 1,140 to 11,842 units across substitute options.

Frequently Asked Questions (FAQ)

Q: Can LTE-4208 directly replace OP295B in existing PCB layouts? A: LTE-4208 maintains identical T 1 3/4 through-hole package and 20° viewing angle, enabling direct PCB footprint compatibility. Circuit design must accommodate maximum forward current reduction from 150mA to 50mA and forward voltage change from 4V to 1.2V.

Q: What wavelength differences exist between substitute options? A: Three wavelengths are available: 880nm (XTHI12 series), 890nm (OP295B original), and 940nm (LTE-4208 and XTNI12 series). Wavelength selection depends on infrared detector spectral response characteristics. Most silicon photodiodes and phototransistors respond across 880nm-940nm range.

Q: Are radial package substitutes mechanically compatible with T 1 3/4 footprints? A: No. Radial packages (XTHI12BF, XTHI12W, XTNI12BF, XTNI12W) require different PCB hole patterns and mounting orientation compared to T 1 3/4 axial packages. Radial substitutes necessitate PCB redesign.

Q: Do all substitute parts operate across the full OP295B temperature range? A: No. OP295B operates -40°C to 100°C, while all substitute parts operate -40°C to 85°C. Applications requiring operation above 85°C cannot use these substitutes.

Q: What is the impact of forward current reduction in substitute parts? A: Substitute parts maximum forward current is 50mA compared to OP295B 150mA. Radiant intensity output will be proportionally reduced. Circuit design must verify adequate signal strength for detector sensitivity at reduced drive current.

Q: Are all substitute parts RoHS3 compliant? A: Yes. LTE-4208, XTHI12BF, XTHI12W, XTNI12BF, and XTNI12W all carry RoHS3 compliance matching OP295B certification status.
