TE Connectivity AMP Connectors 6-747843-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 6-747843-7 is a 37-position D-Sub plug connector with right-angle solder termination, designed for through-hole mounting applications. This connector belongs to the AMPLIMITE HD-20 series and features male pins with a 2-row configuration in shell size 4 (DC, C). The part maintains active product status with 1090 pieces currently in stock.

Substitute parts are identified when equivalent D-Sub connectors share the same core functional specifications: 37-position configuration, 2-row layout, shell size 4, right-angle mounting orientation, solder termination, and compatible electrical ratings. Alternative sources become necessary due to supply chain considerations, manufacturing availability, or specific compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6-747843-7 is determined by strict alignment with the following core parameters:

Primary Matching Criteria:

• Connector style: D-Sub
• Connector type: Plug with male pins
• Position count: 37 positions
• Row configuration: 2 rows
• Shell size: 4 (DC, C)
• Mounting orientation: Right angle
• Termination method: Solder
• Backset spacing: 0.318" (8.08mm)

Secondary Compatibility Parameters:

• Material flammability rating: UL94 V-0
• Operating temperature range: -55°C to 105°C minimum
• Contact finish: Gold
• Shell material: Steel with plating

The identified substitute parts (182-037-113R171 and 621-037-260-013) satisfy all primary matching criteria. Variations in secondary parameters such as current rating, voltage rating specification, shell finish type, and flange feature design do not disqualify substitution when the primary functional parameters align.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (6-747843-7): The TE Connectivity AMP Connectors 6-747843-7 remains the primary specification when RoHS non-compliance is acceptable and REACH-affected materials are permitted in the application. This part delivers the highest current rating at 6A and operates across the full temperature range of -55°C to 105°C. Active product status with 1090 units in stock ensures supply availability.

Substitute Selection (182-037-113R171): The NorComp Inc. 182-037-113R171 serves as the preferred substitute when ROHS3 compliance and REACH-unaffected status are required. This connector maintains the full operating temperature range (-55°C to 105°C) and UL94 V-0 flammability rating. The 5A current rating accommodates most applications requiring the 6A primary part, with the exception of designs operating at maximum current specifications. Panel mount capability provides additional mounting flexibility.

Secondary Substitute Selection (621-037-260-013): The Mercury United Electronics 621-037-260-013 qualifies as a substitute when ROHS3 compliance and REACH-unaffected status are mandatory, and the application operates within a reduced temperature range (-55°C to 85°C). The 3A per contact current rating restricts this connector to lower-power applications. Board edge mounting and shielded features provide specialized functionality for specific circuit board configurations. Bulk packaging accommodates high-volume procurement.

Compliance Considerations: Applications requiring ROHS3 compliance and REACH-unaffected materials must select either 182-037-113R171 or 621-037-260-013. The primary part (6-747843-7) is RoHS non-compliant and REACH-affected, making it unsuitable for regulated environments.

Temperature Range Constraints: The 621-037-260-013 operates only to 85°C maximum, restricting its use in applications requiring the full 105°C upper limit of the primary specification.

Frequently Asked Questions (FAQ)

Q: Can the NorComp Inc. 182-037-113R171 directly replace the TE Connectivity 6-747843-7 in all applications?

A: The 182-037-113R171 provides functional equivalence for applications operating at 5A or below. The primary difference is the reduced current rating (5A versus 6A). Both connectors share identical position count, row configuration, shell size, backset spacing, and operating temperature range. Mounting type variations (panel mount capability on the NorComp part) do not affect through-hole solder termination compatibility.

Q: What are the compliance differences between these three connectors?

A: The TE Connectivity 6-747843-7 is RoHS non-compliant and REACH-affected. Both substitute parts (182-037-113R171 and 621-037-260-013) are ROHS3 compliant and REACH-unaffected. Applications subject to RoHS3 or REACH regulations must use one of the substitute parts.

Q: Is the Mercury United Electronics 621-037-260-013 suitable for high-temperature applications?

A: The 621-037-260-013 operates to a maximum of 85°C, which is 20°C below the primary specification and the NorComp substitute. Applications requiring operation at temperatures between 85°C and 105°C must use either the primary part (6-747843-7) or the NorComp substitute (182-037-113R171).

Q: How do the current ratings affect substitution decisions?

A: The primary part supports 6A, the NorComp substitute supports 5A, and the Mercury United substitute supports 3A per contact. Substitution is valid only when the application current requirement does not exceed the substitute part's rating. A design operating at 5.5A cannot use the NorComp part, and designs exceeding 3A cannot use the Mercury United part.

Q: What is the significance of shell finish differences (tin plated versus nickel plated)?

A: The primary part features tin plating; both substitutes feature nickel plating. Both finishes provide corrosion resistance and electrical conductivity suitable for D-Sub connector applications. The finish difference does not affect functional compatibility in standard operating environments.

Q: Are there mounting type restrictions when substituting these connectors?

A: All three connectors support through-hole, right-angle mounting with solder termination. The NorComp part adds panel mount capability, and the Mercury United part adds board edge mounting. These additional mounting options on the substitutes do not restrict their use in through-hole applications matching the primary specification.

Q: What packaging considerations apply to these substitutes?

A: The primary part and NorComp substitute are supplied in trays; the Mercury United substitute is supplied in bulk. Packaging format does not affect connector functionality but may influence procurement and handling procedures.

Q: Can these connectors be used interchangeably in existing PCB designs?

A: Yes, provided the application current requirement does not exceed the substitute part's rating and the operating temperature range remains within the substitute's specification. The identical backset spacing (0.318"), shell size (4), and solder termination ensure mechanical and electrical compatibility with existing through-hole PCB layouts.
