Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 745355-4 is based on strict electrical and mechanical parameter equivalence within the D-Sub connector category. The substitute part must maintain identical specifications across the following critical parameters:

Electrical Parameters:

• 50-position configuration
• 3-row layout
• Shell size 5 (DD, D)
• 6A current rating
• 125V voltage rating
• Gold contact finish
• Brass contact material

Mechanical Parameters:

• D-Sub plug connector type with male pins
• Right-angle through-hole mounting
• Solder termination
• Mating side flange with 4-40 standard screws
• Steel tin-plated shell
• Operating temperature range -55°C to 105°C
• UL94 V-0 flammability rating

Compliance Parameters:

• Moisture Sensitivity Level 1 (Unlimited)
• ECCN EAR99 classification
• HTSUS 8536.69.4040

The substitute part 5745355-4 meets all these requirements while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 5745355-4 serves as the direct active equivalent to the obsolete 745355-4. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including pin count, shell size, current and voltage ratings, and operating temperature range.

The primary distinction between these parts lies in product status and regulatory compliance. The 745355-4 is classified as obsolete and carries RoHS non-compliant status. The 5745355-4 is an active product with ROHS3 compliance, making it the appropriate selection for new designs and applications requiring current regulatory adherence.

The dielectric material differs between the two parts: the main part uses thermoplastic material, while the substitute employs polyamide (PA) nylon with glass filling. Both materials satisfy the UL94 V-0 flammability requirement and maintain equivalent electrical performance across the specified operating temperature range of -55°C to 105°C.

For applications requiring component replacement or new procurement, the 5745355-4 is the designated active equivalent. Both parts are manufactured by TE Connectivity AMP Connectors within the AMPLIMITE HDP-20 series and are functionally interchangeable at the connector interface level.

Frequently Asked Questions (FAQ)

Q: Can the 5745355-4 directly replace the 745355-4 in existing assemblies?

A: Yes. The 5745355-4 maintains identical electrical and mechanical specifications to the 745355-4 across all critical parameters including pin configuration, shell size, current rating, voltage rating, and mounting type. Both connectors are D-Sub 50-position plugs with right-angle solder termination and are functionally interchangeable at the connector interface.

Q: What is the significance of the product status difference between these parts?

A: The 745355-4 is classified as obsolete, indicating it is no longer in active production. The 5745355-4 is an active product, meaning it is currently manufactured and available for procurement. For new designs and ongoing production requirements, the active 5745355-4 is the appropriate selection.

Q: How does the RoHS compliance difference affect component selection?

A: The 745355-4 is RoHS non-compliant, while the 5745355-4 is ROHS3 compliant. Applications subject to RoHS regulations or customer requirements mandating RoHS compliance must use the 5745355-4. Both parts maintain equivalent electrical performance and reliability characteristics.

Q: Are there differences in the dielectric materials used in these connectors?

A: The 745355-4 uses thermoplastic dielectric material, while the 5745355-4 uses polyamide (PA) nylon with glass filling. Both materials meet the UL94 V-0 flammability rating and maintain equivalent electrical performance across the operating temperature range of -55°C to 105°C.

Q: What is the difference in packaging between these parts?

A: The 745355-4 is supplied in standard packaging, while the 5745355-4 is supplied in bulk packaging. Packaging format does not affect connector performance or compatibility; it relates only to order quantity and handling procedures.

Q: Are both parts manufactured by the same company?

A: Yes. Both the 745355-4 and 5745355-4 are manufactured by TE Connectivity AMP Connectors and belong to the AMPLIMITE HDP-20 series. They share identical design specifications and manufacturing standards.

Q: What are the current and voltage ratings for these connectors?

A: Both connectors are rated for 6A current and 125V voltage. These ratings apply across the entire operating temperature range of -55°C to 105°C.

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

A: Yes. Both connectors are rated for operation up to 105°C and down to -55°C, making them suitable for applications requiring extended temperature ranges within these limits.
