Engineering Selection Recommendations

All substitute parts (EE-SA104, EE-SX1046, EE-SX198, EE-SX199) are active products with full electrical and mechanical equivalence to the obsolete EE-SA102. Selection among these alternatives should be based on product availability and regulatory compliance requirements for the target application.

EE-SA104 and EE-SX1046 maintain RoHS Compliant status. EE-SX198 and EE-SX199 are certified as ROHS3 Compliant, with EE-SX198 marked as REACH Affected and EE-SX199 marked as REACH Unaffected. All parts carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications.

Frequently Asked Questions (FAQ)

Q: Can EE-SA104, EE-SX1046, EE-SX198, and EE-SX199 be used interchangeably with EE-SA102?

A: Yes. All substitute parts maintain identical electrical parameters (current ratings, voltage ratings, response time) and mechanical specifications (sensing distance, mounting type, package configuration). Direct substitution is supported without circuit modification.

Q: What is the primary difference between the substitute parts?

A: The substitute parts differ only in product status (all active versus obsolete EE-SA102) and regulatory compliance certifications. Electrical and mechanical characteristics are identical across all parts.

Q: Are there packaging differences between these parts?

A: EE-SA102 is listed with unspecified packaging. All substitute parts are supplied in Bulk packaging. Confirm packaging requirements for your procurement process.

Q: Which substitute part should be selected for new designs?

A: Any of the active substitute parts (EE-SA104, EE-SX1046, EE-SX198, EE-SX199) are suitable for new designs. Selection should consider regulatory compliance requirements specific to the target application and regional market.

Q: Do these parts require any circuit modifications when substituting for EE-SA102?

A: No circuit modifications are required. All electrical parameters and mechanical mounting specifications are identical, enabling direct pin-for-pin substitution.
