Substitute Part Grouping Explanation

Substitution of the TE Connectivity AMP Connectors 1-50871-9 is determined by strict equivalence across the following critical parameters:

Pin Acceptance Specification: The substitute part must accept pin diameters within the range of 0.056" to 0.065" (1.42mm to 1.65mm) to ensure mechanical compatibility with existing pin configurations.

Termination Method: The substitute must utilize solder termination to maintain compatibility with printed circuit board assembly processes and existing design specifications.

Tail Configuration: The substitute must feature a no-tail design to match the original connector geometry and mounting requirements.

Physical Dimensions: Overall length, mounting hole diameter, flange diameter, and socket depth must remain consistent to ensure proper fit within existing mechanical assemblies and PCB layouts.

Contact Material and Finish: Beryllium copper with gold plating at 30.0µin thickness is required to maintain electrical performance, corrosion resistance, and contact reliability.

Operating Temperature Range: The substitute must support the specified temperature range of -65°C to 125°C for thermal compatibility.

The substitute part 1-5050871-9 meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-5050871-9 is functionally and mechanically equivalent to the obsolete 1-50871-9 across all critical electrical and mechanical parameters. The primary distinction between these components is product status and regulatory compliance.

Product Status Consideration: The main part 1-50871-9 is classified as obsolete, whereas the substitute 1-5050871-9 maintains active manufacturing status. This distinction is significant for long-term supply chain reliability and component availability.

Regulatory Compliance: The substitute part 1-5050871-9 is ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The main part is RoHS non-compliant. For applications subject to RoHS requirements or future regulatory mandates, the substitute part provides compliance assurance.

Operating Temperature Range: The substitute part supports an operating temperature range of -65°C to 126°C, which encompasses and exceeds the main part specification of -65°C to 125°C. This extended upper temperature limit provides additional thermal margin without compromising compatibility.

Electrical and Mechanical Equivalence: All contact materials, finishes, dimensions, and functional specifications remain identical between the main part and substitute. Direct substitution is supported without design modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the 1-5050871-9 substitute directly replace the 1-50871-9 in existing designs?

A: Yes. The 1-5050871-9 is mechanically and electrically equivalent to the 1-50871-9 across all specified parameters. Pin acceptance diameter, solder termination, overall dimensions, contact material, and finish specifications are identical. Direct substitution is supported without design changes.

Q: What is the significance of the obsolete status of the 1-50871-9?

A: Obsolete status indicates that the 1-50871-9 is no longer in active production. This classification creates supply chain risk for new procurements or future replenishment. The active status of the 1-5050871-9 ensures continued availability and manufacturing support.

Q: Are there differences in packaging between these parts?

A: The main part 1-50871-9 is supplied in standard packaging configuration. The substitute part 1-5050871-9 is supplied in bulk packaging. Both packaging formats are suitable for component integration; bulk packaging is typical for high-volume manufacturing operations.

Q: Does the RoHS3 compliance of the 1-5050871-9 affect electrical performance?

A: No. RoHS3 compliance relates to the absence of restricted hazardous substances in the component composition. The electrical performance, contact resistance, and functional characteristics remain identical to the non-compliant main part. Compliance status does not alter electrical specifications.

Q: Is the extended operating temperature range of the 1-5050871-9 a design change?

A: No. The substitute part supports -65°C to 126°C, compared to the main part specification of -65°C to 125°C. This represents an extended upper temperature limit that provides additional thermal margin. The lower temperature limit remains identical. This extended range does not constitute a design change but rather an enhanced specification.

Q: What inventory considerations apply to these parts?

A: The main part 1-50871-9 has 726 pieces in stock. The substitute part 1-5050871-9 has 8906 pieces in stock. The significantly higher inventory level of the substitute part reflects its active manufacturing status and ongoing market demand.

Q: Are there any electrical performance differences between these connector terminals?

A: No. Contact material (beryllium copper), contact finish (gold), finish thickness (30.0µin), and all electrical specifications are identical. Both parts are designed for equivalent electrical performance in solder-terminated applications.
