Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 787171-4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector style (D-Type)
• Connector type (Receptacle, Female Sockets)
• Number of positions (40)
• Number of rows (2)
• Shell size and connector layout (0.050 Pitch x 0.100 Row to Row)
• Termination method (Solder)
• Current rating (1A)
• Voltage rating (30V)
• Operating temperature range (-55°C to 105°C)
• Series designation (AMPLIMITE .050 III)
• Contact material (Phosphor Bronze)
• Shell material and finish (Steel, Nickel Plated)
• Contact finish (Gold)
• Flange feature (Housing/Shell with 2-56 threads)
• Features (Board Lock, Shielded)
• Dielectric material (Thermoplastic)
• Material flammability rating (UL94 V-0)

The identified substitute part 1761028-2 maintains equivalence across all mandatory parameters. Variations in mounting type configuration and regulatory compliance status do not preclude substitution when electrical and mechanical interface requirements are identical.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: TE Connectivity 787171-4

The 787171-4 is the primary specification for applications where the original part number is required. This part maintains active product status and is available in current inventory with 2080 units in stock.

Substitute Selection: TE Connectivity 1761028-2

The 1761028-2 serves as a direct electrical and mechanical substitute when the primary part is unavailable or when regulatory compliance requirements favor RoHS Compliant and REACH Unaffected status. Both parts are manufactured by TE Connectivity within the AMPLIMITE .050 III series and maintain identical electrical performance specifications, current ratings, voltage ratings, and operating temperature ranges.

The 1761028-2 differs from the 787171-4 in the following non-functional aspects:

• RoHS Compliant status (versus Not applicable)
• REACH Unaffected status (versus REACH Affected)
• Mounting type specification excludes Board Edge designation (retains Through Hole and Right Angle)

These differences do not affect electrical compatibility or mechanical interface when both connectors are used in through-hole, right-angle solder applications. Selection between these parts should be based on inventory availability, regulatory compliance requirements of the end application, and specific mounting configuration needs.

Frequently Asked Questions (FAQ)

Q: Can the 1761028-2 be used as a direct replacement for the 787171-4 in all applications?

A: The 1761028-2 is electrically and mechanically equivalent to the 787171-4 for through-hole, right-angle solder mounting applications. Both connectors maintain identical current ratings (1A), voltage ratings (30V), operating temperature ranges (-55°C to 105°C), and contact configurations. The primary difference is regulatory compliance status. Applications requiring RoHS Compliant or REACH Unaffected components should specify the 1761028-2.

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

A: The 787171-4 specifies Board Edge, Through Hole, and Right Angle mounting types, while the 1761028-2 specifies Through Hole and Right Angle mounting types. Both connectors are compatible with through-hole, right-angle solder termination on printed circuit boards. The Board Edge designation on the 787171-4 indicates additional mechanical support capability. For applications utilizing standard through-hole mounting without board edge engagement, both parts are functionally equivalent.

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

A: No. Both the 787171-4 and 1761028-2 utilize phosphor bronze contacts with gold finish, identical shell materials (steel, nickel plated), and identical flange features (housing/shell with 2-56 threads). Contact performance, signal integrity, and electrical characteristics are equivalent.

Q: What is the difference between "REACH Affected" and "REACH Unaffected" status?

A: REACH Affected status indicates the component may contain substances of concern under the REACH regulation. REACH Unaffected status indicates the component does not contain such substances or is exempt from REACH requirements. Applications subject to REACH compliance requirements should specify the 1761028-2.

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

A: Yes, for designs utilizing through-hole, right-angle solder mounting. Both connectors maintain identical electrical specifications, pin configurations, and mechanical interfaces. Designs originally specified with the 787171-4 can be updated to the 1761028-2 without circuit redesign or PCB layout modification, provided the application does not require board edge mounting engagement.

Q: What is the packaging format for both parts?

A: Both the 787171-4 and 1761028-2 are supplied in tube packaging, suitable for automated assembly processes and manual component handling.

Q: Are both parts currently available for procurement?

A: Yes. The 787171-4 has 2080 units in current inventory, and the 1761028-2 has 1291 units in current inventory. Both parts maintain active product status with TE Connectivity.
