Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1734531-4 with the Sullins Connector Solutions NPPN072FJFN-RC is based on alignment of the following critical parameters:

Matching Parameters:

• 14 position connector configuration
• 0.079" (2.00mm) mating pitch
• 2-row layout with 0.079" (2.00mm) row spacing
• Through-hole, right-angle mounting orientation
• Gold contact finish on mating surfaces
• Push-pull fastening mechanism
• -40°C to 105°C operating temperature range
• UL94 V-0 flammability rating
• Board-to-board style application
• Solder termination method
• Square contact geometry
• Phosphor bronze contact material

The primary distinction between these connectors is the connector type designation: the main part is a receptacle, while the substitute is a header. Both are designed to mate with complementary connector types in board-to-board applications. The substitute part maintains electrical and mechanical compatibility through identical pitch, row spacing, mounting configuration, and contact specifications.

Parameter Comparison

Engineering Selection Recommendations

The Sullins Connector Solutions NPPN072FJFN-RC serves as a functional equivalent for the discontinued TE Connectivity 1-1734531-4 based on the following engineering criteria:

Compliance and Regulatory Status: Both connectors maintain RoHS compliance and REACH unaffected status. The substitute part carries ROHS3 compliance, which supersedes the RoHS standard of the original part. Both share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, ensuring consistent regulatory treatment.

Electrical and Mechanical Compatibility: The substitute part maintains identical mating pitch (0.079"), row spacing (0.079"), contact geometry (square phosphor bronze), and operating temperature range (-40°C to 105°C). Both connectors feature gold-plated mating contacts, push-pull fastening, and UL94 V-0 flammability ratings.

Product Availability: The original part is discontinued at DiGi Electronics. The substitute part maintains active product status with higher inventory availability (1209 pieces versus 774 pieces), supporting long-term procurement requirements.

Connector Type Consideration: The original part is designated as a receptacle, while the substitute is designated as a header. In board-to-board connector applications, these designations indicate complementary mating surfaces. System designers must verify that the mating connector on the opposing board is compatible with the selected connector type.

Frequently Asked Questions (FAQ)

Q: Can the Sullins NPPN072FJFN-RC directly replace the TE Connectivity 1-1734531-4 in existing designs?

A: The Sullins connector maintains identical electrical and mechanical specifications including pitch, row spacing, contact finish, operating temperature, and flammability rating. However, the connector type differs (header versus receptacle). Direct replacement is possible only if the mating connector on the opposing board is compatible with a header connector type. System designers must verify mating connector specifications before implementation.

Q: What is the difference between a receptacle and header connector in this context?

A: In board-to-board applications, receptacle and header connectors are complementary connector types designed to mate with each other. A receptacle connector accepts pins from a header connector. The choice between these types depends on the overall system architecture and which board requires the pin-bearing connector versus the socket-bearing connector.

Q: Are there any differences in contact finish specifications between these connectors?

A: The TE Connectivity part specifies 10.0µin (0.25µm) gold plating thickness on mating contacts with tin plating on posts. The Sullins part specifies flash gold plating on both mating contacts and posts. Both provide gold contact surfaces for mating; the thickness specifications differ but both are suitable for the 0.079" (2.00mm) pitch application.

Q: What is the significance of the RoHS3 compliance on the substitute part?

A: ROHS3 compliance indicates adherence to the current Restriction of Hazardous Substances directive. This supersedes earlier RoHS standards and represents current regulatory alignment. Both parts are compliant with applicable RoHS requirements for their respective manufacturing dates.

Q: How do the insulation materials differ between these connectors?

A: The TE Connectivity part uses thermoplastic insulation material. The Sullins part specifies polyamide (PA6T), nylon 6T insulation material. Both materials provide UL94 V-0 flammability ratings and maintain identical insulation height (0.191") and operating temperature range (-40°C to 105°C).

Q: What packaging format is provided for the Sullins substitute part?

A: The Sullins NPPN072FJFN-RC is supplied in tube packaging, as specified in the product data. The original TE Connectivity part packaging format is not specified in the available documentation.

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

A: The TE Connectivity part specifies a 250VAC voltage rating. The Sullins part does not specify a voltage rating in the available documentation. System designers must verify voltage requirements against the Sullins part datasheet before implementation in voltage-critical applications.

Q: What current rating should be considered for these connectors?

A: The TE Connectivity part does not specify a current rating in the available documentation. The Sullins part specifies 1A current rating per contact. System designers must verify current requirements and consult detailed datasheets for both connectors to ensure adequate current-carrying capacity for specific applications.
