Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EE-SJ3-C are identified based on strict equivalence across the following critical parameters:

• Sensing distance: 0.134" (3.4mm)
• Sensing method: Through-Beam
• Output configuration: Phototransistor
• Current - Collector (Ic) (Max): 20 mA
• Voltage - Collector Emitter Breakdown (Max): 30 V
• Response time: 4µs
• Operating temperature range: -25°C ~ 85°C
• Mounting type: Through Hole
• Package / Case: PCB Mount
• Type: Unamplified
• Base product number: EE-SJ3

The EE-SJ3-D meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical and mechanical specifications within the optical sensor through-beam category.

Parameter Comparison

Engineering Selection Recommendations

Both the EE-SJ3-C and EE-SJ3-D are active products from Omron Electronics Inc-EMC Div with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability: EE-SJ3-D has 2481 units in stock compared to 984 units for EE-SJ3-C
• Regulatory compliance: Both parts are ROHS3 compliant and carry EAR99 classification
• Supply chain considerations: EE-SJ3-D is REACH Affected; EE-SJ3-C status is REACH Unaffected

For applications requiring REACH unaffected components, EE-SJ3-C is the appropriate selection. For general applications where REACH compliance is managed at the system level, EE-SJ3-D offers superior stock availability.

Frequently Asked Questions (FAQ)

Q: Can EE-SJ3-D replace EE-SJ3-C in existing designs?

A: Yes. Both parts share identical sensing distance, sensing method, output configuration, electrical ratings, response time, operating temperature range, mounting type, and package specifications. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between EE-SJ3-C and EE-SJ3-D?

A: The parts are parametrically equivalent. Differences exist in REACH regulatory status (EE-SJ3-C is REACH Unaffected; EE-SJ3-D is REACH Affected) and Moisture Sensitivity Level designation. Electrical and mechanical performance is identical.

Q: Are both parts suitable for PCB mount applications?

A: Yes. Both EE-SJ3-C and EE-SJ3-D are configured for PCB mount installation with through-hole mounting type and identical package specifications.

Q: What is the sensing distance for these optical sensors?

A: Both parts operate with a 0.134" (3.4mm) through-beam sensing distance, suitable for slot-type optical sensing applications.

Q: Do these parts require amplification?

A: No. Both EE-SJ3-C and EE-SJ3-D are unamplified phototransistor output sensors. The phototransistor output provides direct signal conditioning without integrated amplification stages.
