Engineering Selection Recommendations

All substitute parts (EE-SX1046, EE-SX198, EE-SX199) are parametrically equivalent to the EE-SA104 and are qualified for direct replacement. Selection among these alternatives should be based on the following factors:

Product Status & Compliance: All parts maintain active product status. EE-SX198 and EE-SX199 carry ROHS3 compliance certification, while EE-SA104 and EE-SX1046 carry RoHS compliance. EE-SX198 is designated as REACH Affected; EE-SX199 is REACH Unaffected.

Inventory Availability: EE-SX199 and EE-SX198 offer the highest inventory levels (4459 and 4432 units respectively), followed by EE-SX1046 (2876 units) and EE-SA104 (1177 units).

Regulatory Requirements: Applications subject to ROHS3 compliance requirements should prioritize EE-SX198 or EE-SX199. Applications with REACH compliance constraints should select EE-SX199 (REACH Unaffected) or EE-SA104/EE-SX1046 (not subject to REACH designation).

Frequently Asked Questions (FAQ)

Q: Can EE-SX1046, EE-SX198, and EE-SX199 be used interchangeably with EE-SA104?

A: Yes. All substitute parts match the core electrical and mechanical parameters of the EE-SA104, including sensing distance, sensing method, output configuration, current ratings, voltage ratings, response time, operating temperature range, mounting type, and package configuration. Direct substitution is valid for applications requiring these specifications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in sensing distance (0.118" / 3mm), sensing method (through-beam), output configuration (phototransistor), maximum forward current (50 mA), maximum collector current (20 mA), collector-emitter breakdown voltage (30 V), response time (4µs), operating temperature range (-25°C to 85°C), mounting type (through hole), package type (PCB mount), and sensor type (unamplified).

Q: Are there differences in compliance certifications between these parts?

A: Yes. EE-SA104 and EE-SX1046 carry RoHS compliance. EE-SX198 and EE-SX199 carry ROHS3 compliance. Additionally, EE-SX198 is REACH Affected, while EE-SX199 is REACH Unaffected. Applications with specific regulatory requirements should select accordingly.

Q: Which substitute part has the best inventory availability?

A: EE-SX199 and EE-SX198 offer the highest inventory levels at 4459 and 4432 units respectively. EE-SX1046 has 2876 units available.

Q: Are all parts manufactured by the same manufacturer?

A: Yes. All parts, including the main part EE-SA104 and all substitutes (EE-SX1046, EE-SX198, EE-SX199), are manufactured by Omron Electronics Inc-EMC Div.
