TE Connectivity 205736-7 D-Sub Receptacle Equivalent & Substitute Parts

Part Overview

The TE Connectivity 205736-7 is a 15-position D-Sub receptacle connector with female sockets, designed for through-hole solder termination applications. This connector belongs to the AMPLIMITE HDP-20 series and is classified as an active product. The connector features a 2-row configuration with shell size 2 (DA, A) layout, rated for 6A current and 125V voltage operation across an extended temperature range of -55°C to 105°C.

Identifying equivalent and substitute parts is necessary when bulk packaging is unavailable, when alternative compliance certifications are required, or when alternative dielectric materials meet specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 205736-7 are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following criteria:

Critical Matching Parameters:

• Connector type (Receptacle, Female Sockets)
• Number of positions (15)
• Number of rows (2)
• Shell size and layout (2 / DA, A)
• Mounting type (Through Hole)
• Termination method (Solder)
• Current rating (6A)
• Voltage rating (125V)
• Operating temperature range (-55°C ~ 105°C)
• Contact material (Phosphor Bronze)
• Shell material and finish (Steel, Yellow Chromate Plated Zinc)
• Flammability rating (UL94 V-0)

Allowable Variations:

• Packaging format (Bulk vs. Tube)
• Contact finish thickness (30.0µin vs. Flash)
• Dielectric material (PBT Glass Filled vs. PA Nylon Glass Filled)
• RoHS compliance status
• REACH status designation

The substitute part 5205736-7 maintains all critical electrical and mechanical parameters while differing only in packaging, dielectric material composition, and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 205736-7 and 5205736-7 are active products from TE Connectivity AMP Connectors and maintain identical electrical and mechanical specifications for D-Sub receptacle applications. Selection between these parts is determined by specific application requirements:

Select 205736-7 when:

• Bulk packaging format is required for high-volume manufacturing operations
• RoHS non-compliant status is acceptable for the application
• PBT (Polybutylene Terephthalate) dielectric material is specified in design requirements
• Contact finish thickness of 30.0µin is required

Select 5205736-7 when:

• Tube packaging format is preferred for component handling and storage
• RoHS compliance certification is required by regulatory or customer specifications
• PA (Polyamide) Nylon dielectric material is acceptable for the application
• Flash gold contact finish meets application requirements
• Higher inventory availability (7004 pcs vs. 770 pcs) is advantageous

Both parts operate across the identical temperature range (-55°C to 105°C), carry the same UL94 V-0 flammability rating, and support the same 6A current and 125V voltage specifications. The dielectric material variation between PBT and PA Nylon does not affect electrical performance within the specified operating parameters, as both are glass-filled formulations rated for the same flammability classification.

Frequently Asked Questions (FAQ)

Q: Can 5205736-7 be used as a direct replacement for 205736-7 in existing designs?

A: Yes. Both connectors are mechanically and electrically identical in all critical parameters. The 15-position D-Sub receptacle configuration, through-hole solder termination, 6A current rating, 125V voltage rating, and -55°C to 105°C operating temperature range are identical. Substitution is valid from an engineering standpoint.

Q: What is the difference between the dielectric materials used in these connectors?

A: The 205736-7 uses Polybutylene Terephthalate (PBT) glass-filled material, while the 5205736-7 uses Polyamide (PA) Nylon glass-filled material. Both materials are glass-filled and rated UL94 V-0. The material difference does not affect electrical performance within the specified operating parameters.

Q: Does the contact finish thickness difference affect performance?

A: The 205736-7 has a specified contact finish thickness of 30.0µin (0.76µm), while the 5205736-7 has a flash gold finish. Both provide gold contact finish for corrosion resistance and conductivity. Flash finish is a thinner application that meets electrical requirements while reducing material usage.

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

A: The 205736-7 is RoHS non-compliant, while the 5205736-7 is RoHS Compliant. RoHS compliance is a regulatory requirement in certain markets and applications. Selection depends on whether the application or end-use market requires RoHS certification.

Q: Are the packaging differences significant for component selection?

A: Packaging format (Bulk vs. Tube) affects handling, storage, and manufacturing processes but does not affect connector performance. Bulk packaging is typically used for high-volume pick-and-place operations, while tube packaging is suitable for manual assembly or lower-volume applications. Select based on manufacturing process requirements.

Q: Can these connectors be used interchangeably in the same PCB assembly?

A: Yes. Both connectors have identical mechanical dimensions, mounting type (through-hole), shell size (2 / DA, A), and flange configuration. They are footprint-compatible and can be used interchangeably in PCB designs without layout modifications.

Q: What is the significance of the inventory difference between these parts?

A: The 205736-7 has 770 pcs in stock, while the 5205736-7 has 7004 pcs in stock. Higher inventory availability may influence lead time and supply chain considerations for production planning.

Q: Are there any temperature or voltage limitations when substituting between these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 105°C) and carry the same voltage rating (125V) and current rating (6A). There are no thermal or electrical limitations when substituting between these connectors.

Q: What does "REACH Affected" vs. "Vendor Undefined" mean in the context of these parts?

A: REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) is a European Union regulation. The 205736-7 is marked as REACH Affected, indicating it is subject to REACH requirements. The 5205736-7 is marked as Vendor Undefined, meaning the vendor has not provided specific REACH status information. Selection depends on whether REACH compliance documentation is required for the application.

Q: Are both connectors suitable for the same voltage and current applications?

A: Yes. Both connectors are rated for 125V and 6A. They are suitable for identical electrical applications within these specifications.
