Engineering Selection Recommendations

All substitute parts listed maintain identical electrical and mechanical specifications to the EE-SJ3-G. Selection between equivalent parts should be based on the following factors:

Compliance Requirements: The EE-SJ3-G carries RoHS Compliant status. Substitute parts EE-SV3-C, EE-SV3-D, EE-SX1071, and EE-SX1088 are ROHS3 Compliant, which represents an updated compliance standard. EE-SV3-B maintains RoHS Compliant status matching the original part.

Regulatory Classification: REACH status varies among substitutes. EE-SV3-B and EE-SX1071 are REACH Affected, while EE-SV3-C and EE-SV3-D are REACH Unaffected. EE-SX1088 is REACH Affected. Regulatory requirements specific to your application or region should guide selection.

Inventory Availability: EE-SX1088 offers the highest inventory level at 14,565 pieces, followed by EE-SV3-B at 5,222 pieces. Lower inventory levels exist for EE-SX1071 (2,620 pieces), EE-SV3-D (1,148 pieces), and EE-SV3-C (936 pieces).

Moisture Sensitivity Level: EE-SV3-B and EE-SV3-D specify MSL 1 (Unlimited), indicating no moisture sensitivity constraints. EE-SJ3-G, EE-SV3-C, EE-SX1071, and EE-SX1088 are not applicable for MSL, which does not affect functional performance.

Frequently Asked Questions (FAQ)

Q: Are all listed parts electrically interchangeable with the EE-SJ3-G?

A: Yes. All substitute parts share identical electrical parameters: 50 mA maximum DC forward current, 20 mA maximum collector current, 30 V maximum collector-emitter breakdown voltage, and 4µs response time. They operate across the same temperature range (-25°C to 85°C) and use the same through-beam sensing method with phototransistor output.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 represents an updated version of the RoHS directive with revised substance restrictions. Both certifications indicate compliance with hazardous substance limitations. The specific regulatory framework applicable to your region or customer requirements should determine which certification is required.

Q: Do differences in REACH status affect part functionality?

A: No. REACH status indicates regulatory classification under the European chemicals regulation but does not alter electrical or mechanical performance. Selection should be based on your supply chain location and regulatory obligations.

Q: Can I use EE-SX1088 as a direct replacement for EE-SJ3-G in existing designs?

A: Yes. EE-SX1088 maintains all critical electrical and mechanical parameters required for through-beam optical sensing at 0.134" (3.4mm) distance. PCB mount footprint and pin configuration are compatible. Verify compliance requirements specific to your application before implementation.

Q: What does MSL 1 (Unlimited) mean for EE-SV3-B and EE-SV3-D?

A: MSL 1 (Unlimited) indicates that these parts have no moisture sensitivity constraints and do not require special handling or storage conditions related to moisture exposure. This simplifies supply chain management compared to parts with higher MSL ratings.

Q: Are there any performance differences between the EE-SV3 series and EE-SX series?

A: No performance differences exist. Both series meet identical electrical specifications for sensing distance, current ratings, voltage ratings, and response time. Series designation reflects internal Omron product categorization but does not indicate functional variation.
