OP295C Infrared Emitter 890nm Equivalent & Substitute Parts

Part Overview

The OP295C is an infrared (IR) emitter manufactured by TT Electronics/Optek Technology, designed for applications requiring 890nm wavelength emission at 150mA forward current. This component features a T 1 3/4 through-hole package with a 20° viewing angle and operates across the temperature range of -40°C to 100°C. The OP295C is classified as obsolete, necessitating identification of active substitute components that maintain functional compatibility for new designs or production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OP295C are grouped based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Wavelength: 880nm–940nm range (near-infrared spectrum compatibility)
• Forward Current: 50mA–150mA (operational current capability)
• Forward Voltage: 1.2V–4V (power supply compatibility)
• Viewing Angle: 20° (optical beam pattern)
• Mounting Type: Through Hole (mechanical fit)
• Package Type: T 1 3/4 or Radial (form factor compatibility)
• Operating Temperature: -40°C minimum to 85°C–100°C maximum
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

Direct Substitutes (Identical Package & Wavelength):

• OP295B: Same manufacturer, same wavelength (890nm), same package (T 1 3/4), active product status

Functional Equivalents (Different Package, Compatible Wavelength & Current):

• LTE-4208: 940nm wavelength, 50mA current, T 1 3/4 package
• LTE-4238: 880nm wavelength, 100mA current, Radial package
• XTHI12BF: 880nm wavelength, 50mA current, Radial package
• XTHI12W: 880nm wavelength, 50mA current, Radial package
• XTNI12BF: 940nm wavelength, 50mA current, Radial package
• XTNI12W: 940nm wavelength, 50mA current, Radial package

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: OP295B

The OP295B is the direct substitute for the OP295C. Both components share identical electrical specifications (890nm wavelength, 150mA forward current, 4V forward voltage) and mechanical packaging (T 1 3/4 through-hole). The OP295B maintains active product status with ROHS3 compliance and equivalent operating temperature range (-40°C to 100°C). This component provides drop-in compatibility for existing circuit designs.

Secondary Recommendations for Alternative Packages:

When circuit board redesign is acceptable, the following active components provide functional equivalence:

• LTE-4208: Maintains T 1 3/4 package compatibility with 940nm wavelength and 50mA current rating. Suitable for applications where lower current operation is acceptable.
• LTE-4238, XTHI12BF, XTHI12W: Provide 880nm wavelength operation with Radial package configuration. Require PCB layout modification but offer active product status and ROHS3 compliance.
• XTNI12BF, XTNI12W: Deliver 940nm wavelength with Radial package. Require PCB layout modification but offer active product status and ROHS3 compliance.

All substitute components maintain ROHS3 compliance and operate within the -40°C to 85°C temperature range, with the exception of OP295B which extends to 100°C.

Frequently Asked Questions (FAQ)

Q: Can OP295B directly replace OP295C without circuit modification?

A: Yes. The OP295B is electrically and mechanically identical to the OP295C. Both components feature 890nm wavelength, 150mA forward current, 4V forward voltage, and T 1 3/4 through-hole packaging. No circuit or PCB layout changes are required.

Q: What is the primary difference between OP295C and OP295B?

A: The OP295C is classified as obsolete, while OP295B maintains active product status. All electrical and mechanical parameters are equivalent.

Q: Can I use LTE-4208 as a substitute for OP295C?

A: LTE-4208 is functionally compatible for applications where the following parameter differences are acceptable: 940nm wavelength (versus 890nm), 50mA maximum forward current (versus 150mA), and 1.2V forward voltage (versus 4V). The T 1 3/4 package maintains mechanical compatibility. Circuit redesign may be required to accommodate the lower current rating and different voltage characteristics.

Q: Why do some substitute parts use Radial packages instead of T 1 3/4?

A: Radial package components (LTE-4238, XTHI12BF, XTHI12W, XTNI12BF, XTNI12W) require different PCB footprints and mounting hole configurations compared to the T 1 3/4 axial package. These components are listed as functional equivalents based on wavelength and current compatibility but require PCB layout modification for implementation.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute components maintain ROHS3 compliance, consistent with the OP295C specification.

Q: What is the operating temperature difference between OP295C and the substitute parts?

A: The OP295C operates from -40°C to 100°C. Most substitute components (LTE-4208, LTE-4238, XTHI12BF, XTHI12W, XTNI12BF, XTNI12W) operate from -40°C to 85°C. The OP295B maintains the full -40°C to 100°C range. Applications requiring operation above 85°C must use OP295B.

Q: Which substitute part offers the highest radiant intensity?

A: XTNI12BF and XTNI12W both provide 25mW/sr @ 50mA radiant intensity, the highest among the listed substitutes. These components operate at 940nm wavelength with Radial packaging.
