ITR8402-F Equivalent & Substitute Parts

Part Overview

The ITR8402-F is an optical sensor manufactured by Everlight Electronics Co Ltd, designed for PCB mount applications with a 0.1" (2.54mm) sensing distance. This phototransistor-based sensor is actively produced and suitable for through-hole mounting in optical detection circuits. Substitute parts may be required due to inventory constraints, design optimization, or application-specific sensing distance requirements while maintaining functional compatibility within the phototransistor output configuration.

Key Parameters

Substitute Part Grouping Explanation

The LTH-301-05 manufactured by LITEON qualifies as a substitute based on the following alignment criteria:

• Output Configuration: Both parts feature phototransistor output, enabling direct functional replacement in detection circuits
• Mounting Type: Both utilize through-hole mounting, compatible with standard PCB assembly processes
• Operating Temperature Range: Both operate across -25°C ~ 85°C, ensuring thermal compatibility in equivalent environments
• Product Status: Both are actively produced, ensuring supply chain continuity
• Category: Both are classified as optical sensors with phototransistor-based detection

The primary difference is sensing distance: ITR8402-F operates at 0.1" (2.54mm) while LTH-301-05 operates at 0.236" (6mm). This distinction requires application-level evaluation based on specific gap or slot width requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the ITR8402-F and LTH-301-05 are active products with established supply availability. Selection between these parts depends on application-specific sensing distance requirements:

• ITR8402-F: Select for applications requiring 0.1" (2.54mm) sensing distance with standard PCB mount configuration
• LTH-301-05: Select for applications requiring 0.236" (6mm) sensing distance with through-beam detection in slot-type configurations

Both parts operate within identical temperature ranges and feature phototransistor output, supporting equivalent circuit design approaches. The LTH-301-05 provides faster response time (4µs versus 15µs), which may be advantageous in high-speed detection applications.

Frequently Asked Questions (FAQ)

Q: Can LTH-301-05 directly replace ITR8402-F in existing designs?

A: Direct replacement is possible only if the application's sensing distance requirement can accommodate the 0.236" (6mm) gap of the LTH-301-05 versus the 0.1" (2.54mm) of the ITR8402-F. PCB layout and mechanical mounting must be re-evaluated for the module-type package configuration.

Q: What is the primary difference between these optical sensors?

A: The primary difference is sensing distance and package type. ITR8402-F uses a compact PCB mount for short-distance detection, while LTH-301-05 is a module with PC pins designed for slot-type through-beam applications at greater distances.

Q: Are both parts suitable for the same operating temperature range?

A: Yes, both parts operate across -25°C ~ 85°C, ensuring thermal compatibility in equivalent environmental conditions.

Q: Does the faster response time of LTH-301-05 affect compatibility?

A: Faster response time (4µs versus 15µs) is generally compatible with existing circuit designs. Circuit performance may improve with the faster response characteristic, but no design modifications are required for basic functionality.

Q: What compliance certifications apply to these parts?

A: Both parts carry ECCN EAR99 classification and HTSUS 8541.41.0000 coding. The LTH-301-05 is ROHS3 compliant. Verify specific compliance requirements for your application and region.
