Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EE-SJ8-B are identified based on strict equivalence of the following critical parameters:

• Sensing distance: 0.315" (8mm)
• Sensing method: Through-Beam
• Output configuration: Phototransistor
• Current ratings: If (Max) 50 mA, Ic (Max) 20 mA
• Voltage rating: Collector Emitter Breakdown (Max) 30 V
• Response time: 4µs, 4µs
• Mounting type: Through Hole
• Package type: PCB Mount
• Sensor type: Unamplified

The EE-SX1070 meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical performance specifications and mechanical compatibility, differing only in operating temperature range and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the EE-SJ8-B and EE-SX1070 are active production parts from Omron Electronics Inc-EMC Div with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

The EE-SJ8-B is RoHS Compliant and suitable for applications with operating temperature requirements up to 85°C. The EE-SX1070 offers ROHS3 Compliant certification and extended operating temperature capability to 95°C, with REACH Affected status noted. The EE-SX1070 also provides higher inventory availability at 2200 units compared to 755 units for the EE-SJ8-B. Both parts maintain identical electrical performance and mechanical compatibility for PCB mount through-hole installation.

Frequently Asked Questions (FAQ)

Q: Can the EE-SX1070 be used as a direct replacement for the EE-SJ8-B?

A: Yes. Both parts share identical sensing distance (0.315" / 8mm), sensing method (through-beam), output configuration (phototransistor), current ratings (If Max 50 mA, Ic Max 20 mA), voltage rating (30 V), response time (4µs, 4µs), and mounting specifications (through hole, PCB mount). Electrical and mechanical compatibility is maintained.

Q: What is the difference in operating temperature range?

A: The EE-SJ8-B operates from -25°C to 85°C, while the EE-SX1070 extends to -25°C to 95°C. Applications requiring operation above 85°C should specify the EE-SX1070.

Q: Are there differences in regulatory compliance?

A: The EE-SJ8-B carries RoHS Compliant certification. The EE-SX1070 carries ROHS3 Compliant certification and is marked as REACH Affected. Compliance requirements should be verified against application and regional specifications.

Q: Do both parts use the same PCB mount package?

A: Yes. Both parts are configured for PCB mount through-hole installation with identical mechanical compatibility.

Q: Which part should be selected for new designs?

A: Selection depends on operating temperature requirements and regulatory compliance needs. For applications operating above 85°C or requiring ROHS3 compliance, the EE-SX1070 is appropriate. For standard applications within the -25°C to 85°C range, either part meets functional requirements.
