Omron EE-SV3-C Optical Sensor: Equivalent & Substitute Parts

Part Overview

The Omron EE-SV3-C is an optical sensor designed for through-beam detection applications. This phototransistor-based sensor operates at a sensing distance of 0.134" (3.4mm) and is mounted directly to PCBs. The component is currently active in production and widely available. Alternative part numbers within the Omron EE-SV3 and EE-SJ3 series provide equivalent functionality for applications requiring component substitution due to supply constraints, design revisions, or inventory management.

Engineering Selection Recommendations

All substitute parts listed are active products manufactured by Omron Electronics Inc-EMC Div and maintain full electrical and mechanical compatibility with the EE-SV3-C. Selection among these equivalents should be based on:

Compliance Requirements: The EE-SV3-C and EE-SV3-D carry ROHS3 Compliant status. The EE-SJ3-G, EE-SX1071, and EE-SX1088 also meet ROHS3 requirements. The EE-SV3-B is RoHS Compliant. All parts are classified under ECCN EAR99 and HTSUS 8541.49.8000.

REACH Status: The EE-SV3-C and EE-SV3-D are REACH Unaffected. The EE-SJ3-G, EE-SX1071, and EE-SX1088 are REACH Affected. Applications subject to REACH regulations should specify accordingly.

Moisture Sensitivity: The EE-SV3-C and EE-SX1071 are Not Applicable for MSL. The EE-SV3-B and EE-SV3-D carry MSL 1 (Unlimited). The EE-SX1088 is Not Applicable for MSL.

Inventory Availability: EE-SX1088 offers the highest stock level at 14,565 pieces. EE-SV3-B provides 5,222 pieces. Other alternatives range from 936 to 2,620 pieces.

Frequently Asked Questions (FAQ)

Q: Can EE-SV3-C be directly replaced with EE-SJ3-G?

A: Yes. Both parts share identical electrical specifications (50 mA If, 20 mA Ic, 30 V VCE breakdown, 4µs response time) and mechanical parameters (0.134" sensing distance, through-beam method, phototransistor output, through-hole PCB mount). The primary difference is the base product number designation (EE-SV3 versus EE-SJ3).

Q: What is the difference between EE-SV3-C and EE-SV3-B?

A: Both parts are electrically and mechanically identical. The differences are in compliance certifications: EE-SV3-C is ROHS3 Compliant and REACH Unaffected with Not Applicable MSL, while EE-SV3-B is RoHS Compliant and REACH Affected with MSL 1 (Unlimited). EE-SV3-B has significantly higher inventory availability (5,222 vs. 936 pieces).

Q: Are all substitute parts suitable for the same PCB layout?

A: Yes. All substitute parts use identical through-hole PCB mount packaging and mechanical dimensions. No PCB redesign is required for substitution.

Q: Which substitute part should be selected for REACH-compliant applications?

A: The EE-SV3-C and EE-SV3-D are REACH Unaffected and are the appropriate choices for applications requiring REACH compliance. The EE-SJ3-G, EE-SX1071, and EE-SX1088 are REACH Affected.

Q: Do all substitute parts operate within the same temperature range?

A: Yes. All listed parts operate from -25°C to 85°C, ensuring thermal compatibility across the entire substitute group.

Q: What is the fastest available substitute with the highest inventory?

A: EE-SX1088 combines the highest inventory level (14,565 pieces) with identical response time (4µs, 4µs) and all core electrical specifications of the EE-SV3-C.
