Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub receptacle housings is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Connector style (D-Sub)
• Connector type (Receptacle for Female Contacts)
• Number of positions (9)
• Number of rows (2)
• Shell size and layout (1 / DE, E)
• Mounting type (Free Hanging In-Line)
• Flange feature (Cable Side 4-40)
• Contact type (Signal)

Acceptable Variation Parameters:

• Shell material finish (Steel with Tin or Nickel plating)
• Dielectric material (Thermoplastic or PBT)
• Product status (Active substitutes for Obsolete main part)
• RoHS compliance status
• Manufacturer identity

The identified substitutes meet all critical matching parameters and are therefore electrically and mechanically compatible with the 745907-1 housing.

Engineering Selection Recommendations

TE Connectivity 1658643-1 (Direct Substitute)

The 1658643-1 is the primary equivalent for the obsolete 745907-1. Both parts share identical manufacturer lineage (TE Connectivity AMP Connectors), series designation (AMPLIMITE HDP-20), and all critical electrical and mechanical parameters. The 1658643-1 is active in production status and carries ROHS3 compliance certification with REACH Unaffected status, addressing regulatory requirements that the original part does not meet. Shell finish thickness is specified at 200µin (5.08µm). This part is supplied in bulk packaging.

NorComp Inc. 170-009-273L010 (Similar Substitute)

The 170-009-273L010 provides functional equivalence through matching all critical connector parameters. This part differs in manufacturer identity, series designation (170 series), shell finish material (Nickel Plated versus Tin Plated), and dielectric material (PBT versus Thermoplastic). The part carries ROHS3 compliance and REACH Unaffected status. Operating temperature range is specified as -50°C to 125°C. This part is supplied in tray packaging. Selection of this substitute is appropriate when manufacturer standardization on NorComp components is required or when the specified operating temperature range is a system requirement.

Frequently Asked Questions (FAQ)

Q: Can the 1658643-1 be used as a direct replacement for the 745907-1?

A: Yes. The 1658643-1 is mechanically and electrically compatible with the 745907-1. Both parts share identical connector style, type, position count, row configuration, shell size, mounting method, and flange specifications. The 1658643-1 is the active production equivalent.

Q: What is the primary difference between the 1658643-1 and 170-009-273L010?

A: The primary differences are manufacturer identity, shell finish material (Tin Plated versus Nickel Plated), and dielectric material composition (Thermoplastic versus PBT). Both parts are mechanically and electrically compatible with the 745907-1 and meet current RoHS3 and REACH compliance requirements.

Q: Does the shell finish material difference between substitutes affect compatibility?

A: No. Both Tin Plated and Nickel Plated steel shells meet the mechanical and electrical requirements for D-Sub receptacle housings in this configuration. Selection between finishes depends on system-level corrosion resistance requirements and environmental exposure conditions.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both the 1658643-1 and 170-009-273L010 carry ROHS3 compliance certification. The original 745907-1 is RoHS non-compliant, making substitution necessary for applications requiring regulatory compliance.

Q: What packaging options are available for these substitutes?

A: The 1658643-1 is supplied in bulk packaging. The 170-009-273L010 is supplied in tray packaging. Packaging selection depends on procurement volume and handling requirements.

Q: Does the NorComp 170-009-273L010 have specified operating temperature limits?

A: Yes. The 170-009-273L010 specifies an operating temperature range of -50°C to 125°C. The 745907-1 and 1658643-1 do not have specified operating temperature ranges in the provided data.

Q: Are contacts included with these housings?

A: No. All three parts (745907-1, 1658643-1, and 170-009-273L010) are housings only. Contacts must be procured separately and are not included.

Q: Can these parts be intermixed in the same assembly?

A: Yes. All three parts are mechanically and electrically compatible and can be used interchangeably within the same assembly, provided that system-level requirements for compliance, operating temperature, and environmental exposure are met.
