Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 747832-3 is determined by the following critical parameters that must align across candidate parts:

Mandatory Matching Parameters:

• Connector Type: Plug, Male Pins
• Number of Positions: 9
• Number of Rows: 2
• Shell Size, Connector Layout: 1 (DE, E)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Finish: Gold, Flash
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Shell Material Finish: Tin Plated (original) to Nickel Plated (substitutes)
• Current Rating: 6A (original) to 3A per Contact (substitutes) — represents reduced current capacity
• Voltage Rating: 125V (original) to unspecified (substitutes)
• Operating Temperature: -55°C ~ 105°C (original) to -55°C ~ 85°C (substitutes) — represents reduced upper temperature limit
• Flange Feature: Housing/Shell (4-40) to variations including Unthreaded or Mating Side Female Screwlock
• Contact Material: Brass (original) to Copper Alloy (substitutes)
• Dielectric Material: Unspecified (original) to Polyester Thermoplastic or Polyamide (PA9T), Nylon 9T (substitutes)

The substitute parts identified maintain the core D-Sub 9-position plug configuration with right-angle solder termination and through-hole mounting, enabling functional replacement in applications where the reduced electrical ratings and temperature range are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes for Active Production:

The NorComp 183-009-113R171 and 183-009-113R561 connectors are the preferred substitutes for the obsolete TE Connectivity 747832-3. Both NorComp parts maintain the original operating temperature range of -55°C ~ 105°C and offer ROHS3 compliance, addressing regulatory requirements that the original part does not meet. The 183-009-113R171 provides a 5A current rating, closely matching the original 6A specification, while the 183-009-113R561 includes board lock and female screwlock features on the mating side.

Secondary Substitutes with Operational Constraints:

The Mercury United Electronics 625-009-262-042, 625-009-262-031, and 625-009-262-032 connectors are functionally compatible substitutes with the following constraints: these parts operate at a reduced maximum temperature of -55°C ~ 85°C and provide a 3A per contact current rating, both lower than the original specification. These Mercury parts are suitable for applications where the reduced electrical and thermal ratings are acceptable. All Mercury parts offer ROHS3 compliance and active product status.

Compliance Considerations:

All identified substitute parts are ROHS3 compliant, whereas the original TE Connectivity 747832-3 is RoHS non-compliant. Selection of any substitute part addresses RoHS regulatory requirements for new designs and production environments requiring compliance.

Mounting Type Variations:

The NorComp parts support panel mount in addition to through-hole mounting, providing installation flexibility. The Mercury parts support board edge mounting in addition to through-hole mounting. The original TE Connectivity part specifies through-hole and right-angle mounting only.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 183-009-113R171 directly replace the TE Connectivity 747832-3?

A: The NorComp 183-009-113R171 is a functional equivalent for the TE Connectivity 747832-3 in applications where the electrical and thermal specifications are compatible. Both connectors share the same 9-position D-Sub plug configuration, right-angle solder termination, through-hole mounting, and operating temperature range of -55°C ~ 105°C. The NorComp part provides a 5A current rating compared to the original 6A specification. The primary difference is the shell material finish (nickel plated versus tin plated) and the addition of panel mount capability. The NorComp part is ROHS3 compliant, addressing regulatory requirements not met by the obsolete original part.

Q: What is the difference between the Mercury 625-009-262-042, 625-009-262-031, and 625-009-262-032 connectors?

A: All three Mercury parts share the same core specifications: 9-position D-Sub plug, right-angle solder termination, board edge and through-hole mounting, 3A per contact current rating, and -55°C ~ 85°C operating temperature range. The primary differences are in the flange feature configuration. The 625-009-262-042 includes a 4-40 threaded housing/shell flange. The 625-009-262-031 features an unthreaded housing/shell flange. The 625-009-262-032 includes a 4-40 threaded housing/shell flange. All three parts are ROHS3 compliant and active products.

Q: Are the Mercury connectors suitable for high-temperature applications?

A: The Mercury 625-009-262-042, 625-009-262-031, and 625-009-262-032 connectors operate at a maximum temperature of -55°C ~ 85°C, which is 20°C lower than the original TE Connectivity 747832-3 specification of -55°C ~ 105°C. These Mercury parts are not suitable for applications requiring operation above 85°C. For high-temperature applications, the NorComp 183-009-113R171 or 183-009-113R561 are the appropriate substitutes, as both support the full -55°C ~ 105°C temperature range.

Q: What is the significance of the backset spacing difference between parts?

A: Backset spacing defines the distance from the connector mounting surface to the contact mating plane. The original TE Connectivity 747832-3 specifies 0.590" (14.99mm) backset spacing. The Mercury parts (625-009-262-042, 625-009-262-031, 625-009-262-032) specify 0.584" (14.84mm) backset spacing, a difference of 0.006" (0.15mm). The NorComp parts (183-009-113R171, 183-009-113R561) maintain the original 0.590" (14.99mm) backset spacing. This difference may affect mating connector alignment and should be verified for specific application requirements.

Q: How does the current rating difference affect part selection?

A: The original TE Connectivity 747832-3 provides a 6A current rating. The NorComp 183-009-113R171 and 183-009-113R561 provide a 5A current rating, representing a 1A reduction. The Mercury parts provide a 3A per contact rating, representing a 3A reduction. Current rating determines the maximum continuous current the connector can safely carry without exceeding temperature limits. Applications requiring the full 6A capacity must use the NorComp parts. Applications with current requirements of 5A or less can use either NorComp part. Applications with current requirements of 3A or less can use any of the identified substitutes.

Q: What is the difference between the NorComp 183-009-113R171 and 183-009-113R561?

A: Both NorComp parts are 9-position D-Sub plugs with identical electrical and thermal specifications: 5A current rating, -55°C ~ 105°C operating temperature, and ROHS3 compliance. The primary difference is the flange feature configuration. The 183-009-113R171 includes a 4-40 threaded housing/shell flange. The 183-009-113R561 includes a female screwlock feature on the mating side with a 4-40 threaded configuration and board lock capability. The 183-009-113R561 provides additional mechanical retention through the screwlock mechanism, suitable for applications requiring secure mating connector locking.

Q: Are all substitute parts RoHS compliant?

A: All identified substitute parts are ROHS3 compliant. The original TE Connectivity 747832-3 is RoHS non-compliant. Selection of any substitute part addresses RoHS regulatory requirements for new designs and production environments requiring compliance with RoHS directives.

Q: Can the substitute parts be used in the same PCB footprint as the original part?

A: The NorComp 183-009-113R171 and 183-009-113R561 maintain the same backset spacing (0.590" / 14.99mm) as the original TE Connectivity 747832-3, enabling direct PCB footprint compatibility. The Mercury parts specify a different backset spacing (0.584" / 14.84mm), which may require PCB layout verification or modification. The mounting type variations (panel mount for NorComp, board edge for Mercury) should also be evaluated against the specific application mounting requirements.
