Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 748636-1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: D-Sub, High Density
• Connector Type: Receptacle for Female Contacts
• Number of Positions: 44
• Number of Rows: 3
• Shell Size, Connector Layout: 3 (DB, B) High Density
• Contact Type: Signal
• Mounting Type: Free Hanging (In-Line)
• Flange Feature: Housing/Shell (Unthreaded)
• Features: Shielded
• Shell Material, Finish: Steel, Tin Plated
• Color: Black
• Series: AMPLIMITE HDP-22

The substitute part 5748636-1 maintains complete functional and mechanical compatibility with the original 748636-1 across all specified parameters. The primary distinction between these components is product status and compliance certification, with the substitute part classified as active and RoHS compliant, whereas the original part is obsolete and RoHS non-compliant.

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 5748636-1

The 5748636-1 is the direct equivalent substitute for the obsolete 748636-1. Selection of this substitute is supported by the following engineering criteria:

Product Status Alignment: The substitute part is classified as active, ensuring continued manufacturer support, availability, and technical documentation access. The original part is obsolete, limiting future procurement options and technical resources.

Compliance Certification: The substitute part carries RoHS compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution. The original part is RoHS non-compliant, which may restrict use in applications subject to RoHS directives.

Functional Equivalence: Both parts maintain identical specifications across all critical connector parameters including connector style, type, position count, row configuration, shell size, contact type, mounting method, shielding, shell material, and color.

Material Specification Difference: The substitute part specifies polyamide (PA) nylon glass-filled dielectric material, compared to the original thermoplastic specification. Both materials are suitable for D-Sub high-density housing applications and maintain equivalent electrical and mechanical performance characteristics within the specified parameter set.

Availability: The substitute part demonstrates higher inventory availability (1506 units versus 798 units), supporting both immediate procurement needs and long-term supply chain planning.

Frequently Asked Questions (FAQ)

Q: Can the 5748636-1 directly replace the 748636-1 in existing applications?

A: Yes. The 5748636-1 maintains complete functional and mechanical compatibility with the 748636-1 across all specified connector parameters. Both parts are D-Sub high-density 44-position receptacles with identical shell size, mounting configuration, shielding, and material finish specifications.

Q: What is the difference in dielectric material between these parts?

A: The original 748636-1 uses thermoplastic dielectric material, while the substitute 5748636-1 uses polyamide (PA) nylon glass-filled material. Both materials are suitable for D-Sub high-density housing applications and provide equivalent electrical and mechanical performance within the specified parameter range.

Q: Why is the 748636-1 classified as obsolete?

A: The 748636-1 is classified as obsolete by the manufacturer. The active equivalent 5748636-1 is available for new designs and ongoing production requirements.

Q: Does the 5748636-1 meet RoHS compliance requirements?

A: Yes. The 5748636-1 is RoHS compliant. The original 748636-1 is RoHS non-compliant. Applications subject to RoHS directives require use of the compliant substitute part.

Q: Are there packaging differences between these parts?

A: The substitute part 5748636-1 is available in bulk packaging. The original part packaging specification is not provided in the technical documentation.

Q: Do both parts include contacts?

A: No. Both the 748636-1 and 5748636-1 are housing-only components. Contacts are not included and must be sourced separately.

Q: What is the inventory status for each part?

A: The original 748636-1 has 798 units in stock. The substitute 5748636-1 has 1506 units in stock, providing higher availability for procurement planning.

Q: Are these parts from the same manufacturer?

A: Yes. Both parts are manufactured by TE Connectivity AMP Connectors and belong to the AMPLIMITE HDP-22 series.
