Engineering Selection Recommendations

The 5749192-1 is the direct substitute for the obsolete 749192-1. Both parts are manufactured by TE Connectivity and maintain identical electrical and mechanical specifications across all critical parameters including position count, cable exit angle, shielding configuration, and material composition.

The primary distinction between the two parts is product status and regulatory compliance. The 749192-1 is classified as obsolete and carries RoHS non-compliant status. The 5749192-1 is an active product with RoHS compliant certification, making it the appropriate selection for new designs and ongoing procurement where regulatory compliance is required.

Both parts share identical moisture sensitivity levels and export classification codes. The substitute part demonstrates higher inventory availability, supporting reliable supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 5749192-1 be used as a direct replacement for the 749192-1?

A: Yes. The 5749192-1 is a direct equivalent substitute. All electrical and mechanical parameters are identical, including position count, cable exit angle, shielding type, material composition, and assembly features.

Q: What is the primary reason to transition from 749192-1 to 5749192-1?

A: The 749192-1 is obsolete. The 5749192-1 is an active product offering continued availability and RoHS compliance certification, which is required for many applications and regulatory environments.

Q: Are there any compatibility differences between these two parts?

A: No. Both parts are designed for the AMPLIMITE .050 III series and maintain identical specifications for round cable applications with 180° cable exit and shielded construction.

Q: Does the RoHS compliance difference affect physical or electrical compatibility?

A: No. RoHS compliance relates to material composition restrictions and regulatory requirements, not to the physical or electrical performance of the connector backshell. Both parts maintain identical material specifications and functional characteristics.

Q: What is the packaging difference between these parts?

A: The 749192-1 packaging is not specified in available documentation. The 5749192-1 is supplied in box packaging.

Q: Are both parts suitable for applications requiring shielded 40-position D-Sub backshells?

A: Yes. Both parts are shielded two-piece backshells with 40 positions, spring lock features, and strain relief hardware. The 5749192-1 is recommended for new applications due to its active status and RoHS compliance.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
