Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5749721-5 is the direct functional equivalent for the obsolete 5750458-5 connector. Selection of the substitute part is based on the following engineering criteria:

Product Status Consideration: The 5750458-5 is classified as obsolete, creating supply chain risk for new production and field replacements. The 5749721-5 maintains active product status with TE Connectivity, ensuring long-term availability and manufacturing continuity.

Electrical and Mechanical Equivalence: All critical electrical parameters (current rating, voltage rating, operating temperature range) and mechanical parameters (connector geometry, pitch, mounting configuration, termination method) are identical between the main part and substitute. The connectors are fully interchangeable at the circuit board level.

Compliance and Certification: Both parts meet UL94 V-0 flammability requirements and maintain RoHS compliance. The substitute part carries ROHS3 compliance, representing current regulatory alignment. Both parts are REACH unaffected and carry MSL 1 (unlimited) moisture sensitivity rating, indicating no special handling requirements.

Material Specification Difference: The dielectric material differs between parts (polyester versus thermoplastic). Both materials are standard for D-Type connector applications and provide equivalent electrical insulation performance within the specified voltage and temperature ranges. This material difference does not affect functional compatibility or performance in the specified operating environment.

Availability and Inventory: The substitute part 5749721-5 has significantly higher inventory availability (1860 pieces) compared to the obsolete main part (897 pieces), supporting both immediate procurement and long-term supply security.

Frequently Asked Questions (FAQ)

Q: Can the 5749721-5 be used as a direct replacement for the 5750458-5 in existing designs?

A: Yes. The 5749721-5 is electrically and mechanically equivalent to the 5750458-5. All connector parameters including pin count, pitch, current rating, voltage rating, operating temperature range, and solder termination are identical. The connectors are pin-for-pin compatible and require no circuit board redesign.

Q: What is the difference between the dielectric materials used in these connectors?

A: The 5750458-5 uses polyester dielectric material, while the 5749721-5 uses thermoplastic dielectric material. Both materials provide equivalent electrical insulation performance within the specified voltage rating of 30V and operating temperature range of -55°C to 105°C. The material difference does not affect connector function or compatibility.

Q: Why is the 5750458-5 listed as obsolete?

A: The 5750458-5 has been discontinued by TE Connectivity. The 5749721-5 represents the current active equivalent in the AMPLIMITE .050 III series and is the recommended part for new designs and replacement applications.

Q: Are there any differences in RoHS compliance between these parts?

A: Both parts are RoHS compliant. The 5750458-5 carries RoHS compliance status, while the 5749721-5 carries ROHS3 compliance status, which represents alignment with current regulatory requirements. Both parts meet the same environmental and material restriction standards.

Q: What is the packaging difference between these connectors?

A: The 5750458-5 packaging is not specified in the available documentation. The 5749721-5 is supplied in tube packaging, which is standard for D-Type connectors and provides protection during storage and handling. Packaging does not affect connector performance or compatibility.

Q: Are moisture sensitivity levels the same for both parts?

A: Yes. Both the 5750458-5 and 5749721-5 carry MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture control or baking requirements during storage, handling, or assembly.

Q: Can these connectors be used interchangeably in high-temperature applications?

A: Yes. Both connectors are rated for operation across the identical temperature range of -55°C to 105°C. They are fully interchangeable for applications within this temperature specification.

Q: What is the current-carrying capacity of these connectors?

A: Both connectors are rated for 1A per contact. The total current capacity depends on the number of contacts used in the specific application. The 50-position configuration allows for multiple parallel current paths if required by the circuit design.
