ITR20004 Equivalent & Substitute Parts

Part Overview

The ITR20004 is a reflective optical sensor manufactured by Everlight Electronics Co Ltd, classified as an opto interrupter with phototransistor output. This component operates as a reflective optical sensor in a 4-DIP (0.157", 4.00mm) through-hole package configuration. The ITR20004 is currently listed as obsolete, necessitating identification of functionally equivalent substitute components for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the ITR20004 is based on strict electrical and mechanical parameter matching within the optical sensor category. The primary substitution criterion is functional equivalence across the following parameters:

Electrical Equivalence Parameters:

• Sensing method: Reflective
• Output type: Phototransistor
• Voltage - Collector Emitter Breakdown (Max): 30 V
• Current - Collector (Ic) (Max): 50 mA
• Current - DC Forward (If) (Max): 50 mA
• Operating temperature range: -25°C ~ 85°C

Mechanical Compatibility Considerations:

• Package type and form factor differences require circuit board layout evaluation
• Mounting method differences (through-hole versus surface mount) necessitate PCB redesign

The ITR8307 qualifies as a substitute based on matching electrical specifications and sensing characteristics, despite differences in package configuration and mounting methodology.

Parameter Comparison

Engineering Selection Recommendations

The ITR8307 serves as the primary substitute for the obsolete ITR20004 based on electrical parameter equivalence. Both components share identical specifications for voltage breakdown, collector current, forward current, and operating temperature range. Both employ reflective sensing methodology with phototransistor output architecture.

The ITR8307 maintains active product status with Everlight Electronics Co Ltd, ensuring ongoing availability and supply chain continuity. The component is RoHS3 compliant, meeting current environmental and regulatory requirements.

Implementation Considerations:

Substitution requires circuit board redesign due to package configuration differences. The ITR20004 utilizes through-hole mounting in 4-DIP format, while the ITR8307 employs surface-mount technology in 4-SMD flat-lead configuration. Response time differs marginally (15µs versus 20µs), which may require timing circuit evaluation in applications with critical temporal constraints.

Frequently Asked Questions (FAQ)

Q: Can the ITR8307 directly replace the ITR20004 without circuit modification?

A: No. While electrical specifications are identical, the mounting methods differ fundamentally. The ITR20004 is through-hole mounted; the ITR8307 is surface-mounted. PCB layout and footprint redesign are required.

Q: What are the key electrical parameters that make ITR8307 equivalent to ITR20004?

A: Equivalence is established through matching voltage breakdown (30 V), collector current (50 mA maximum), forward current (50 mA maximum), operating temperature range (-25°C to 85°C), sensing method (reflective), and output type (phototransistor).

Q: Does the response time difference between ITR20004 (15µs) and ITR8307 (20µs) affect substitution suitability?

A: Response time difference must be evaluated within specific application requirements. The 5µs differential may be significant in high-speed switching applications but negligible in standard detection circuits. Circuit timing analysis is necessary.

Q: Is the ITR8307 compliant with current environmental standards?

A: Yes. The ITR8307 is RoHS3 compliant. The ITR20004 status is listed as REACH Unaffected.

Q: What is the sensing distance specification for these components?

A: The ITR20004 sensing distance is not specified in available documentation. The ITR8307 operates at 0.039" (1mm) sensing distance. Application-specific distance requirements must be evaluated independently.

Q: Are both components available from the same manufacturer?

A: Yes. Both the ITR20004 and ITR8307 are manufactured by Everlight Electronics Co Ltd.
