TE Connectivity 748568-1 D-Sub High Density Receptacle Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 748568-1 is a D-Sub high density receptacle housing designed for 62-position female contact applications. This connector is part of the AMPLIMITE HDP-22 series and features a 3-row configuration with shell size 4 (DC, C) high density layout. The part is currently classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support and procurement planning. Active alternatives are available from TE Connectivity and NorComp Inc. that maintain functional and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 748568-1 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: 62
• Number of rows: 3
• Shell size and layout: 4 (DC, C) High Density
• Contact type: Signal
• Mounting type: Free Hanging (In-Line)
• Flange feature: Housing/Shell (Unthreaded)

Acceptable Variations:

• Shell finish material (tin plated or nickel plated) and finish thickness
• Dielectric material composition (polyamide-based formulations)
• Packaging format (bulk, tray)
• Product status (active substitutes for obsolete main part)
• Compliance certifications (RoHS3 compliance preferred for new designs)

The identified substitute parts maintain full mechanical and electrical compatibility within the D-Sub high density connector category while offering improved availability and compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 1658684-1

The TE Connectivity 1658684-1 is the direct equivalent substitute for the obsolete 748568-1. Both parts are manufactured by TE Connectivity within the AMPLIMITE HDP-22 series and share identical electrical and mechanical specifications. The 1658684-1 offers the following advantages:

• Active product status with ongoing availability
• RoHS3 compliance for regulatory alignment with current standards
• REACH unaffected status for environmental compliance
• Specified shell finish thickness (200µin / 5.08µm) for consistent plating quality
• Bulk packaging format for production environments

Secondary Substitute: NorComp 180-062-273L000

The NorComp 180-062-273L000 provides an alternative source for D-Sub high density 62-position receptacle housings. This part maintains full mechanical and electrical compatibility through identical connector geometry and contact configuration. Selection of this substitute is appropriate when:

• Multi-source procurement strategy is required
• Nickel plating finish is preferred over tin plating
• Operating temperature range of -50°C to 100°C is specified
• Tray packaging format aligns with assembly processes
• RoHS3 and REACH compliance requirements are met

Both substitute parts eliminate the obsolescence risk associated with the 748568-1 while maintaining full form, fit, and function compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1658684-1 be used as a direct replacement for the 748568-1 in existing designs?

A: Yes. The 1658684-1 is a direct equivalent substitute. Both parts share identical connector style, type, position count, row configuration, shell size, mounting type, and flange features. The primary difference is product status (active versus obsolete) and compliance certifications (RoHS3 compliant versus non-compliant).

Q: What is the difference between tin plating and nickel plating finishes?

A: The 748568-1 and 1658684-1 use tin plating, while the NorComp 180-062-273L000 uses nickel plating. Both finishes provide corrosion resistance and electrical conductivity. Selection between them depends on application-specific environmental and performance requirements not specified in this reference.

Q: Are contacts included with these housing parts?

A: No. All three parts (748568-1, 1658684-1, and 180-062-273L000) are housings only. Female contacts must be sourced separately and are not included with the housing purchase.

Q: What does RoHS3 compliance mean for component selection?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations. The 1658684-1 and 180-062-273L000 are RoHS3 compliant, while the 748568-1 is non-compliant. For new designs and systems subject to RoHS regulations, the compliant substitutes are required.

Q: Can the NorComp 180-062-273L000 be used in applications requiring tin plating?

A: The NorComp part uses nickel plating instead of tin plating. Substitution is appropriate only if the application does not have specific finish material requirements. The TE Connectivity 1658684-1 maintains the tin plating finish of the original 748568-1.

Q: What is the significance of the operating temperature range specified for the NorComp part?

A: The NorComp 180-062-273L000 specifies an operating temperature range of -50°C to 100°C. This parameter is not specified for the TE Connectivity parts. Selection of the NorComp substitute is appropriate when this temperature range meets application requirements.

Q: How do packaging formats (bulk versus tray) affect component selection?

A: Packaging format does not affect electrical or mechanical compatibility. The 1658684-1 is supplied in bulk packaging, while the 180-062-273L000 is supplied in tray packaging. Selection depends on assembly process requirements and inventory management practices.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life with no moisture sensitivity precautions required. Both the 748568-1 and 1658684-1 carry MSL 1 rating. The NorComp part lists MSL as not applicable, indicating no moisture sensitivity constraints.
