TE Connectivity 748333-7 D-Sub Contact Equivalent & Substitute Parts

Part Overview

The TE Connectivity 748333-7 is a D-Sub contact male pin designed for crimp termination with 22-28 AWG wire gauges. This component is classified as obsolete and is part of the AMPLIMITE HDP-22 series. Due to its obsolete status, equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production and field service applications. The part exhibits non-compliance with RoHS standards and is subject to REACH regulations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 748333-7 is determined by the following critical parameters:

Primary Substitution Criteria:

• Contact Type: Male Pin
• Contact Termination: Crimp
• Wire Gauge Compatibility: 22-28 AWG or overlapping range
• Contact Material: Brass
• Contact Finish: Gold
• Contact Form: Stamped
• Series Compatibility: AMPLIMITE HDP-22 or equivalent high-density D-Sub series

Substitution Logic:

The direct substitute 1658670-4 (TE Connectivity) maintains identical electrical and mechanical specifications within the same AMPLIMITE HDP-22 series. This part is classified as active and RoHS3 compliant, providing a direct functional replacement with improved compliance status.

The similar substitute 180-101-170L001 (NorComp Inc.) operates within a narrower wire gauge range (24-26 AWG), which falls within the original specification envelope (22-28 AWG). This part is from the NorComp 180 series and is RoHS3 compliant. The wire gauge restriction represents a functional limitation compared to the original part.

Parameter Comparison

Engineering Selection Recommendations

1658670-4 (Direct Substitute - Recommended for Primary Selection)

The TE Connectivity 1658670-4 is the preferred substitute for the obsolete 748333-7. Both parts share identical specifications within the AMPLIMITE HDP-22 series, including wire gauge range (22-28 AWG), contact material, finish type, and termination method. The 1658670-4 carries active product status and RoHS3 compliance, eliminating regulatory concerns associated with the original non-compliant part. Inventory availability (39,665 pieces) ensures supply continuity. This substitute requires no design modification and provides direct functional equivalence.

180-101-170L001 (Similar Substitute - Conditional Selection)

The NorComp 180-101-170L001 serves as an alternative when TE Connectivity parts are unavailable. This part maintains compatibility with the core electrical and mechanical requirements: male pin contact, crimp termination, brass material, and gold flash finish. However, the wire gauge specification is restricted to 24-26 AWG, which represents a subset of the original 22-28 AWG range. This limitation restricts application to designs utilizing only 24-26 AWG conductors. The part is RoHS3 compliant and carries active product status. Selection of this substitute requires confirmation that the application wire gauge falls within the 24-26 AWG envelope.

Frequently Asked Questions (FAQ)

Q: Can the 1658670-4 be used as a direct replacement for 748333-7 without design changes?

A: Yes. The 1658670-4 maintains identical electrical and mechanical specifications within the AMPLIMITE HDP-22 series. No design modifications are required. The primary difference is improved RoHS3 compliance status.

Q: What is the wire gauge limitation of the 180-101-170L001 substitute?

A: The 180-101-170L001 is specified for 24-26 AWG wire gauges, compared to the original 22-28 AWG range. Applications using 22-23 AWG or 27-28 AWG conductors cannot use this substitute without conductor gauge modification.

Q: Are all three parts compatible within the same D-Sub connector assembly?

A: The 748333-7 and 1658670-4 are fully compatible within AMPLIMITE HDP-22 assemblies. The 180-101-170L001 is compatible with NorComp 180 series D-Sub connectors and may have different mechanical fit characteristics in TE Connectivity assemblies. Mechanical compatibility must be confirmed for cross-manufacturer applications.

Q: What is the significance of the RoHS compliance difference?

A: The 748333-7 is RoHS non-compliant, while both substitutes (1658670-4 and 180-101-170L001) are RoHS3 compliant. For applications subject to RoHS regulations or customer requirements, the compliant substitutes are mandatory. For legacy systems without RoHS mandates, the original part remains functionally equivalent.

Q: How does the contact form specification affect substitution?

A: All three parts use stamped contact forms, ensuring consistent mechanical and electrical performance. The stamped form is a manufacturing process that does not affect functional substitution eligibility.

Q: What packaging differences exist between these parts?

A: The 748333-7 is supplied in unspecified packaging, the 1658670-4 in bulk packaging, and the 180-101-170L001 in tray packaging. Packaging differences do not affect electrical or mechanical compatibility but may influence procurement and handling procedures.

Q: Is the MSL rating identical across all three parts?

A: Yes. All three parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
