ITR9702-F Equivalent & Substitute Parts

Part Overview

The ITR9702-F is an optical sensor manufactured by Everlight Electronics Co Ltd, classified as a through-beam phototransistor slotted module. This component is designed for applications requiring non-contact object detection through a 0.157" (4mm) sensing distance. The part maintains Active product status with 870 units in current inventory stock.

Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameter ranges for slotted optical sensor modules. Substitution becomes necessary due to supply constraints, lead time requirements, or inventory availability across different manufacturers while maintaining system compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ITR9702-F are identified based on the following critical parameters that define functional equivalence:

Sensing Method: Through-Beam operation is mandatory for substitution compatibility.

Output Configuration: Phototransistor or Transistor output types are functionally equivalent for this application category.

Collector Current (Ic) Rating: Maximum 20 mA is the baseline requirement; substitute parts must meet or exceed this specification.

Collector-Emitter Breakdown Voltage: 30 V minimum is required for circuit protection compatibility.

Operating Temperature Range: -25°C to 85°C defines the environmental operating envelope.

Mounting Type: Through Hole mounting is required for mechanical compatibility.

Package Configuration: Slotted Module form factor is essential for optical path alignment.

Compliance Standards: ROHS3 compliance is mandatory for regulatory equivalence.

The LTH-301-07 from Lite-On Inc. qualifies as a substitute based on alignment across these critical parameters, despite variations in sensing distance and response time specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ITR9702-F and LTH-301-07 maintain Active product status with ROHS3 compliance certification, qualifying them for equivalent use in through-beam optical sensing applications. The ITR9702-F offers 870 units in current inventory, while the LTH-301-07 provides significantly higher availability at 12,491 units.

The LTH-301-07 demonstrates superior response time performance (3µs to 4µs versus 15µs) and increased forward current capability (60 mA versus 50 mA), while maintaining identical collector current and breakdown voltage specifications. The sensing distance differential (0.200" versus 0.157") reflects the physical slot width variation between manufacturers but does not preclude functional substitution in applications where the detection gap accommodates the 0.043" (1.08mm) difference.

Selection between these parts should be based on inventory availability, lead time requirements, and specific application sensing distance constraints. Both parts satisfy the core electrical and mechanical requirements for through-beam phototransistor module applications.

Frequently Asked Questions (FAQ)

Q: Can the LTH-301-07 directly replace the ITR9702-F in existing designs?

A: The LTH-301-07 is functionally equivalent for through-beam optical sensing applications. Both parts share identical collector current (20 mA), breakdown voltage (30 V), operating temperature range (-25°C to 85°C), and mounting configuration (Through Hole, Slotted Module). The primary design consideration is the sensing distance difference: 0.200" (5.08mm) for LTH-301-07 versus 0.157" (4mm) for ITR9702-F. Verify that your mechanical slot width accommodates the LTH-301-07 dimensions before substitution.

Q: What is the significance of the response time difference between these parts?

A: The ITR9702-F specifies 15µs response time, while the LTH-301-07 offers 3µs to 4µs response time. Response time defines the sensor's switching speed when detecting object presence or absence. The LTH-301-07's faster response provides superior performance for high-speed detection applications. If your application operates at lower switching frequencies, both parts are functionally compatible.

Q: Are there mechanical compatibility concerns with the PC Pins configuration on the LTH-301-07?

A: The LTH-301-07 features PC Pins (printed circuit board pins) within its Module, PC Pins, Slot Type package. The ITR9702-F uses a standard Slotted Module configuration. Both employ Through Hole mounting. Verify that your PCB footprint and pin spacing accommodate the LTH-301-07's specific pin configuration before implementation.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the ITR9702-F and LTH-301-07 are ROHS3 compliant and carry EAR99 ECCN classification. They satisfy equivalent regulatory requirements for industrial and commercial optical sensor applications.

Q: Which part should be selected based on availability?

A: The LTH-301-07 maintains significantly higher inventory (12,491 units) compared to the ITR9702-F (870 units). For applications where sensing distance tolerance permits, the LTH-301-07 offers superior supply chain reliability and reduced lead time risk.
