TE Connectivity 749246-1 D-Sub Receptacle Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 749246-1 is a D-Sub receptacle housing designed for 15-position female contact applications within the AMPLIMITE HDP-20 series. This connector functions as a housing component for D-shaped connectors in free-hanging, in-line mounting configurations with integrated backshell, latch lock, and shielding features.

The 749246-1 carries an obsolete product status, necessitating identification of functionally equivalent alternatives for ongoing procurement and system maintenance. Active substitute components maintain identical electrical and mechanical specifications while offering current manufacturing availability and updated compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 749246-1 is determined by strict equivalence across all electrical and mechanical parameters. The substitute component must maintain identical specifications in the following critical areas:

Electrical Parameters: Connector style (D-Sub), connector type (receptacle for female contacts), number of positions (15), number of rows (2), shell size and layout (2 DA, A), contact type (signal), and dielectric material composition (polyamide nylon, glass filled).

Mechanical Parameters: Mounting type (free hanging, in-line), flange feature location (mating side), integrated features (backshell, latch lock, shielded), shell material and finish (steel, tin plated), shell finish thickness (200µin / 5.08µm), and color (black).

Series Compatibility: All substitute parts must belong to the AMPLIMITE HDP-20 series to ensure compatibility with existing contact sets and mating connectors.

The substitute part 5749246-1 satisfies all equivalence criteria and represents a direct functional replacement within the same product series.

Parameter Comparison

Engineering Selection Recommendations

The 5749246-1 serves as the direct functional equivalent for the obsolete 749246-1 component. Both parts maintain identical electrical and mechanical specifications across all critical parameters, ensuring seamless integration into existing assemblies and systems.

The primary distinction between these components is product lifecycle status and regulatory compliance. The 749246-1 is classified as obsolete with non-compliant RoHS status, while the 5749246-1 maintains active product status with full RoHS compliance. This compliance improvement aligns with current environmental and regulatory requirements without introducing any functional or dimensional changes.

Both components share identical moisture sensitivity levels (MSL 1, Unlimited), export classifications (EAR99), and tariff codes (8538.90.8180), confirming their interchangeability from procurement, logistics, and regulatory perspectives.

For new designs and ongoing procurement activities, the 5749246-1 is the appropriate selection due to its active manufacturing status and improved compliance certifications. For legacy system maintenance requiring the original 749246-1 specification, the 5749246-1 provides direct substitution without design modification or system re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the 5749246-1 directly replace the 749246-1 in existing assemblies?

A: Yes. The 5749246-1 is a direct functional equivalent with identical electrical and mechanical specifications. No design modifications, re-qualification, or system changes are required for substitution.

Q: What is the primary reason for substituting the 749246-1?
