TE Connectivity 745135-2 D-Sub Connector Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 745135-2 is a D-Sub connector housing plug designed for 37-position male contact applications. This component functions as the shell assembly for D-Sub connectors in the AMPLIMITE HDP-20 series, featuring a cable-side flange with 4-40 mounting holes and grounding indents. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional and mechanical compatibility for ongoing production and field replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 745135-2 are identified based on strict equivalence across the following critical parameters: connector style (D-Sub), connector type (plug for male contacts), position count (37), row configuration (2), shell size and layout (4 DC, C), mounting type (free hanging in-line), flange feature (cable side 4-40), and presence of grounding indents. All substitute parts maintain identical mechanical interfaces and contact accommodation specifications. Variations in shell material finish, dielectric material composition, and product status are documented but do not affect mechanical or electrical interchangeability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 745135-4 is the direct manufacturer equivalent and primary substitute for the obsolete 745135-2. Both parts share identical series designation (AMPLIMITE HDP-20) and mechanical specifications. The 745135-4 is currently in active production status with ROHS3 compliance and REACH unaffected certification, addressing regulatory requirements that the original part does not meet. Shell finish differs from tin-lead to tin plating with specified thickness of 200µin (5.08µm), maintaining corrosion protection within equivalent parameters.

NorComp 170-037-173L010 provides an alternative cross-manufacturer substitute with identical mechanical and electrical interface specifications. This part is manufactured by NorComp Inc. within the 170 series and maintains active product status with ROHS3 compliance and REACH unaffected designation. The dielectric material differs from polyamide to polybutylene terephthalate (PBT), and shell finish is nickel plated rather than tin based. Operating temperature range is specified as -50°C to 125°C. Moisture sensitivity level is not applicable for this alternative.

Selection between the two active substitutes depends on supply chain requirements, regulatory compliance mandates, and material composition specifications for the target application. Both alternatives maintain full mechanical and electrical interchangeability with the original 745135-2 across all critical interface parameters.

Frequently Asked Questions (FAQ)

Q: Can the 745135-4 directly replace the obsolete 745135-2 in existing designs?

A: Yes. The 745135-4 maintains identical mechanical interface specifications, including shell size (4 DC, C), position count (37), row configuration (2), mounting type (free hanging in-line), and flange feature (cable side 4-40). Both parts belong to the AMPLIMITE HDP-20 series and accommodate the same contact configurations.

Q: What is the primary difference between the 745135-2 and 745135-4?

A: The 745135-4 is the active production equivalent with updated compliance certifications. The 745135-2 uses tin-lead plating and is RoHS non-compliant, while the 745135-4 features tin plating with 200µin thickness and ROHS3 compliance. Both maintain identical functional specifications.

Q: Is the NorComp 170-037-173L010 mechanically compatible with the TE Connectivity alternatives?

A: Yes. The NorComp part maintains identical shell size (4 DC, C), position count (37), row configuration (2), mounting type, and flange specifications. Mechanical interchangeability is confirmed across all interface parameters.

Q: What material differences exist between the substitute parts?

A: The 745135-2 and 745135-4 use polyamide (PA) nylon glass-filled dielectric material. The NorComp 170-037-173L010 uses polybutylene terephthalate (PBT) glass-filled dielectric. Shell finishes differ: 745135-2 uses tin-lead plating, 745135-4 uses tin plating (200µin), and 170-037-173L010 uses nickel plating. These material variations do not affect mechanical or electrical interchangeability.

Q: Are there packaging differences between the substitute parts?

A: Yes. The 745135-2 is supplied in unspecified packaging, the 745135-4 is supplied in bulk packaging, and the 170-037-173L010 is supplied in tray packaging. Packaging format does not affect component functionality or interchangeability.

Q: Which substitute part should be selected for new designs requiring RoHS compliance?

A: Both active substitutes (745135-4 and 170-037-173L010) are ROHS3 compliant. The 745135-2 is RoHS non-compliant and unsuitable for applications with regulatory compliance requirements.

Q: Does the operating temperature specification affect part selection?

A: The NorComp 170-037-173L010 specifies an operating temperature range of -50°C to 125°C. Operating temperature data is not provided for the TE Connectivity parts (745135-2 and 745135-4). Temperature requirements for the target application should be evaluated against available specifications.

Q: Are contacts included with these connector housings?

A: No. All three parts (745135-2, 745135-4, and 170-037-173L010) are housing assemblies only. Contacts must be sourced separately and are not included with the housing purchase.
