TE Connectivity 207661-3 D-Sub Receptacle Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 207661-3 is a D-Sub receptacle housing for female contacts in a 37-position configuration. This connector belongs to the AMPLIMITE HDP-20 series and features a shell size 4 (DC, C) layout with cable-side flange mounting. The part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing system maintenance, repair, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of D-Sub receptacle housings is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Connector style (D-Sub)
• Connector type (Receptacle for Female Contacts)
• Number of positions (37)
• Number of rows (2)
• Shell size and connector layout (4 / DC, C)
• Mounting type (Free Hanging / In-Line)
• Flange feature (Cable Side with 4-40 specification)
• Contact type (Signal)

Secondary Compatibility Parameters:

• Shell material and finish composition
• Dielectric material composition
• Color specification
• Physical dimensions and mechanical fit

The substitute parts identified maintain equivalence across all primary criteria. Variations in shell finish material (tin-plated versus nickel-plated) and dielectric composition (polyamide glass-filled versus polybutylene terephthalate) represent acceptable substitutions where mechanical and electrical performance requirements remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 5207661-3

The 5207661-3 represents the direct successor to the obsolete 207661-3 within the TE Connectivity product line. Both parts share identical mechanical specifications, connector layout, and mounting characteristics. The 5207661-3 maintains the same shell material (steel, tin-plated) and finish thickness (200µin / 5.08µm). The primary distinction is product status: the 5207661-3 is active and carries RoHS compliance certification, whereas the 207661-3 is obsolete and non-compliant. The dielectric material composition differs slightly (polyamide nylon without glass fill versus glass-filled polyamide nylon), but this variation does not affect mechanical or electrical compatibility. The 5207661-3 is available in bulk packaging with higher inventory levels (1757 pcs) compared to the original part.

Secondary Substitute: NorComp Inc. 170-037-273L010

The 170-037-273L010 provides cross-manufacturer equivalence for applications requiring D-Sub 37-position receptacle housings with identical mechanical specifications. This part maintains all critical parameters: 37 positions, 2-row configuration, shell size 4 (DC, C), cable-side flange mounting, and free-hanging in-line installation. The primary material differences include nickel plating (versus tin plating) and polybutylene terephthalate dielectric material (versus polyamide nylon). The 170-037-273L010 includes specified operating temperature range (-50°C ~ 125°C) and carries ROHS3 compliance with REACH unaffected status. This part is available in tray packaging with 1091 pcs in stock.

Compliance Considerations:

For applications subject to RoHS or REACH regulatory requirements, the 5207661-3 (RoHS Compliant, REACH Affected) or 170-037-273L010 (ROHS3 Compliant, REACH Unaffected) must be selected in place of the non-compliant 207661-3. The choice between these two active alternatives depends on specific regulatory jurisdiction and material composition requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5207661-3 directly replace the obsolete 207661-3 in existing assemblies?

A: Yes. The 5207661-3 maintains identical mechanical specifications, connector layout, mounting type, and flange configuration. Both parts are TE Connectivity AMPLIMITE HDP-20 series components with 37-position, 2-row D-Sub receptacle housings. The primary difference is product status and regulatory compliance. No physical modification or redesign is required for substitution.

Q: What is the difference between tin-plated and nickel-plated shell finishes?

A: Both finishes provide corrosion resistance and electrical conductivity. Tin plating (207661-3 and 5207661-3) offers lower contact resistance and is standard for signal-level applications. Nickel plating (170-037-273L010) provides enhanced durability in harsh environments and higher temperature applications. The choice depends on environmental exposure and application requirements. Both finishes are compatible with standard D-Sub mating cycles.

Q: Are the dielectric materials (polyamide nylon versus polybutylene terephthalate) interchangeable?

A: Yes, for standard D-Sub receptacle housing applications. Both polyamide nylon and polybutylene terephthalate are established dielectric materials for D-Sub connectors. The 170-037-273L010 uses PBT, which offers slightly different thermal and mechanical properties compared to polyamide nylon. Both materials maintain the required electrical insulation and mechanical strength for 37-position D-Sub housings. Material selection does not affect connector compatibility or mating performance.

Q: What packaging options are available for these substitute parts?

A: The 207661-3 is supplied in unspecified packaging with 962 pcs in stock. The 5207661-3 is available in bulk packaging with 1757 pcs in stock. The 170-037-273L010 is supplied in tray packaging with 1091 pcs in stock. Packaging format does not affect component functionality or compatibility; selection depends on procurement and inventory management requirements.

Q: Does the NorComp 170-037-273L010 include an operating temperature specification?

A: Yes. The 170-037-273L010 specifies an operating temperature range of -50°C ~ 125°C. The TE Connectivity parts (207661-3 and 5207661-3) do not include published operating temperature specifications. For applications with defined temperature requirements, the 170-037-273L010 provides explicit thermal performance data.

Q: Are contacts included with these D-Sub receptacle housings?

A: No. All three parts (207661-3, 5207661-3, and 170-037-273L010) are housings only. Female contacts must be procured separately and inserted into the housing. Contact selection and installation are independent of housing substitution.

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

A: The 5207661-3 is the recommended choice for new designs requiring TE Connectivity components, as it is active, RoHS compliant, and maintains identical specifications to the original 207661-3. The 170-037-273L010 is suitable for applications requiring cross-manufacturer sourcing, ROHS3 compliance, or specified operating temperature performance. Both parts are active and available in production quantities.
