Substitute Part Grouping Explanation

Substitution of the obsolete EE-SH3-B is determined by strict equivalence across all critical electrical and mechanical parameters. All substitute parts maintain identical specifications for sensing distance (0.134" / 3.4mm), sensing method (through-beam), output configuration (phototransistor), current ratings (If max 50 mA, Ic max 20 mA), voltage breakdown (30 V), response time (4µs), operating temperature range (-25°C to 85°C), mounting type (through hole), and package configuration (PCB mount). All substitutes are unamplified phototransistor sensors.

The substitute parts identified are: EE-SJ3-G, EE-SV3-B, EE-SV3-C, EE-SV3-D, EE-SV3-G, EE-SX1071, EE-SX1088, EE-SX1096, and EE-SX138. These parts share identical parametric specifications with the main part and differ only in product status (active versus obsolete), packaging format, and regulatory compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can EE-SJ3-G directly replace EE-SH3-B in existing designs?

A: Yes. EE-SJ3-G maintains identical electrical specifications (50 mA If max, 20 mA Ic max, 30 V VCE breakdown), response time (4µs), operating temperature range (-25°C to 85°C), sensing distance (0.134" / 3.4mm), and through-hole PCB mount configuration. The primary difference is product status (active versus obsolete) and packaging format (bulk versus unspecified).

Q: What is the difference between RoHS and ROHS3 compliance among the substitute parts?

A: Both certifications indicate compliance with hazardous substance restrictions. ROHS3 represents a more recent revision of the RoHS directive. Parts marked ROHS3 Compliant (EE-SV3-C, EE-SV3-D, EE-SX1071, EE-SX1088) meet current regulatory standards. Parts marked RoHS Compliant (EE-SJ3-G, EE-SV3-B, EE-SV3-G, EE-SX1096, EE-SX138) also meet compliance requirements. Selection should align with your application's regulatory requirements.

Q: Are all substitute parts available in the same packaging as EE-SH3-B?

A: Most substitute parts are available in bulk packaging. EE-SV3-G and EE-SH3-B have unspecified packaging designations. All parts share identical PCB mount configuration and through-hole mounting type, ensuring mechanical compatibility in circuit board designs.

Q: Which substitute part offers the best supply availability?

A: EE-SX1088 provides the highest inventory level at 14,565 pieces, followed by EE-SV3-B at 5,222 pieces. Both are active products with ROHS3 and RoHS compliance respectively, making them suitable for immediate production deployment.

Q: Do all substitute parts maintain the same response time as EE-SH3-B?

A: Yes. All substitute parts maintain identical response time specifications of 4µs, 4µs, ensuring equivalent switching performance in through-beam optical sensing applications.
