Key Parameters

Substitute Part Grouping Explanation

Substitution of the 748677-5 is determined by strict equivalence across the following critical parameters:

• Connector Type & Series: AMPLIMITE HD-20 series D-Sub backshell
• Position Count: 50-position configuration
• Shell Size: D-size compatibility
• Cable Exit Orientation: 180° shielded exit
• Mechanical Interface: Two-piece backshell design with 4-40 mating screws
• Material Composition: ABS plastic with nickel over copper plating
• Shielding Configuration: Shielded construction

The substitute part 5748677-5 maintains identical electrical and mechanical specifications across all these parameters, with the primary distinction being product status transition from obsolete to active and RoHS compliance upgrade.

Parameter Comparison

Engineering Selection Recommendations

The 5748677-5 is the direct functional equivalent to the 748677-5 for all D-Sub backshell applications requiring 50-position, 180° shielded cable exit configurations within the AMPLIMITE HD-20 series.

Product Status Consideration: The 748677-5 is classified as obsolete. The 5748677-5 maintains active product status, ensuring continued availability and manufacturer support for new designs and production requirements.

Compliance Upgrade: The 5748677-5 achieves RoHS compliance, whereas the 748677-5 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements or customer specifications mandating RoHS-compliant components.

Mechanical and Electrical Equivalence: Both parts are identical in connector type, position count, shell size, cable exit angle, shielding configuration, material composition, plating specification, and mating hardware. No design modifications are required for substitution.

Inventory and Packaging: The 5748677-5 is available in bulk packaging with 2000 units in stock, compared to 696 units of the obsolete 748677-5. Bulk packaging designation indicates standard production quantities suitable for manufacturing operations.

Frequently Asked Questions (FAQ)

Q: Can the 5748677-5 directly replace the 748677-5 in existing designs?

A: Yes. The 5748677-5 is mechanically and electrically identical to the 748677-5 across all specified parameters, including position count, shell size, cable exit orientation, shielding, material composition, and mating hardware. No design modifications are required.

Q: What is the primary difference between these two parts?

A: The 5748677-5 is the active production equivalent with RoHS compliance, whereas the 748677-5 is obsolete and RoHS non-compliant. Both parts are functionally identical for D-Sub backshell applications.

Q: Are there any compatibility concerns when substituting the 5748677-5 for the 748677-5?

A: No compatibility concerns exist. Both parts are designed for identical D-Sub connector configurations with 50-position, D-size shell, 180° shielded cable exit, and 4-40 mating screws.

Q: What does the packaging designation "Bulk" mean for the 5748677-5?

A: Bulk packaging indicates standard production quantities supplied by the manufacturer, typically in quantities suitable for manufacturing operations rather than individual component packaging.

Q: Are both parts suitable for applications requiring RoHS compliance?

A: Only the 5748677-5 is RoHS compliant. The 748677-5 is RoHS non-compliant and is not suitable for applications with RoHS regulatory requirements.

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

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Are there any export or regulatory restrictions on these parts?

A: Both parts are classified under ECCN EAR99 and HTSUS 8538.90.8180, indicating standard commercial electronic components with no additional export restrictions beyond standard regulations.
