Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 787171-9 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 (100)
• 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)
• Shell material and finish (Steel, Nickel Plated)
• Contact finish (Gold)
• Contact material (Phosphor Bronze)
• Flammability rating (UL94 V-0)
• Features (Board Lock, Shielded)

The substitute part TE Connectivity 1761028-5 meets all mandatory matching parameters. The primary difference is the mounting type specification: the 787171-9 includes board edge mounting capability, while the 1761028-5 specifies through-hole and right-angle mounting only. Both connectors are from the same AMPLIMITE .050 III series and maintain functional and electrical equivalence for applications requiring 100-position D-type receptacle connectivity.

Parameter Comparison

Engineering Selection Recommendations

Compliance Considerations:

The 787171-9 is RoHS non-compliant and REACH Affected, reflecting its obsolete status and legacy manufacturing timeline. The substitute part 1761028-5 is RoHS Compliant and REACH Unaffected, providing improved regulatory alignment for new designs and systems subject to environmental compliance requirements.

Both connectors carry the UL94 V-0 flammability rating and maintain identical electrical and mechanical specifications across all critical parameters. Selection between these parts depends on regulatory requirements and mounting configuration needs.

Mounting Configuration:

The 787171-9 supports board edge mounting in addition to through-hole and right-angle mounting. The 1761028-5 supports through-hole and right-angle mounting only. Applications requiring board edge mounting must retain the 787171-9 or identify alternative connector families that support this mounting configuration.

Inventory and Availability:

The 1761028-5 maintains higher inventory availability (1748 units) compared to the 787171-9 (905 units), supporting sustained supply for legacy system support and field replacement requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1761028-5 directly replace the 787171-9 in all applications?

A: The 1761028-5 provides direct electrical and mechanical equivalence for applications using through-hole or right-angle mounting. Applications requiring board edge mounting must use the 787171-9, as the 1761028-5 does not support this mounting configuration.

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

A: The 787171-9 is RoHS non-compliant and REACH Affected due to its obsolete status and legacy manufacturing. The 1761028-5 is RoHS Compliant and REACH Unaffected. For systems subject to environmental compliance regulations or procurement policies requiring RoHS compliance, the 1761028-5 is the appropriate selection.

Q: Are the electrical specifications identical between these connectors?

A: Yes. Both connectors maintain identical current rating (1A), voltage rating (30V), operating temperature range (-55°C to 105°C), contact material (Phosphor Bronze), contact finish (Gold), and shell material (Steel, Nickel Plated).

Q: What is the difference in packaging between these parts?

A: The 1761028-5 is supplied in tube packaging. The 787171-9 packaging specification is not provided in the technical data.

Q: Are both connectors from the same product series?

A: Yes. Both the 787171-9 and 1761028-5 belong to the TE Connectivity AMPLIMITE .050 III series, ensuring design and interface consistency.

Q: What connector positions and row configuration do these parts support?

A: Both connectors provide 100 positions arranged in 2 rows with 0.050 pitch and 0.100 row-to-row spacing, maintaining identical contact density and layout.
