Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5646759-1 is the direct substitute for the obsolete TE Connectivity Erni 124118. Selection of this substitute part is based on the following engineering criteria:

Product Status Consideration: The original part is classified as obsolete, while the substitute is active product status. This ensures continued availability, manufacturing support, and compliance with current regulatory standards.

Regulatory Compliance: Both parts maintain RoHS compliance and REACH unaffected status, satisfying environmental and hazardous substance restrictions. The substitute part carries RoHS Compliant designation, confirming adherence to current directives.

Electrical and Mechanical Equivalence: All critical parameters including connector type, position count, pitch, mounting configuration, and termination method are identical. The operating temperature range of -55°C to 125°C is maintained across both parts.

Contact and Shielding Specifications: Gold contact finish is preserved in the substitute part with specified contact finish thickness of 30.0µin (0.76µm). Shielding is maintained through upper shield construction, providing equivalent electromagnetic protection.

Current and Voltage Ratings: The substitute part provides specified current rating of 1.5 A and voltage rating of 750Vrms, establishing defined electrical performance parameters for system design.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity AMP 5646759-1 be used as a direct replacement for the TE Connectivity Erni 124118?

A: Yes. The substitute part meets all critical electrical and mechanical parameters. Both connectors share identical pitch, position count, mounting type, and operating temperature range. Physical dimensions and connector style are equivalent, enabling direct substitution in existing designs and applications.

Q: What is the difference between shielded and upper shield configurations?

A: Both configurations provide electromagnetic shielding for the connector assembly. The shielded designation on the original part and upper shield designation on the substitute part indicate equivalent shielding functionality. The upper shield construction on the substitute part provides the same level of electromagnetic protection required for backplane connector applications.

Q: Are there packaging differences between these parts?

A: The original part packaging is not specified in the documentation. The substitute part is supplied in tube packaging. Packaging format does not affect electrical or mechanical compatibility; it pertains only to handling, storage, and logistics considerations.

Q: What is the significance of the contact finish thickness specification on the substitute part?

A: The substitute part specifies contact finish thickness of 30.0µin (0.76µm) for the gold plating. This specification defines the durability and wear characteristics of the contact surface. Both parts utilize gold contact finish, ensuring equivalent electrical conductivity and corrosion resistance.

Q: Why is the original part classified as obsolete?

A: Obsolete classification indicates the part is no longer manufactured by the original supplier. The substitute part from TE Connectivity AMP Connectors maintains active product status, ensuring ongoing availability and manufacturing support for current and future applications.

Q: Are the electrical ratings specified for both parts?

A: The original part does not specify voltage or current ratings in the provided documentation. The substitute part specifies 1.5 A current rating and 750Vrms voltage rating. These ratings establish the electrical performance envelope for the substitute part in backplane connector applications.

Q: What is Moisture Sensitivity Level 1 (Unlimited)?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. Both parts carry this designation, confirming equivalent moisture sensitivity characteristics.
