Substitute Part Grouping Explanation

Substitution of the obsolete 1-645947-6 terminal is determined by strict alignment of electrical and mechanical parameters that ensure functional compatibility within connector assemblies. The primary substitution criteria are:

Critical Matching Parameters:

• Accepts Pin Diameter: 0.015" ~ 0.021" (0.38mm ~ 0.53mm)
• Termination Type: Solder
• Category: Terminals (Pin Receptacle)

The substitute part 1-5645947-6 maintains identical pin diameter acceptance specifications and solder termination methodology, establishing functional equivalence for applications requiring pin receptacle connectivity in this size class. Both parts are manufactured by TE Connectivity AMP Connectors, ensuring design consistency and manufacturing standards alignment.

The transition from Obsolete to Active product status in the substitute part enables continued component availability for new designs and legacy system support without requiring circuit redesign or connector interface modification.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-5645947-6 is the appropriate selection for applications currently specified with 1-645947-6 terminals. The obsolete status of the original part creates supply chain risk and limits procurement options for ongoing production and field service requirements.

Selection Basis:

The substitute part maintains functional equivalence through identical pin diameter acceptance range (0.015" ~ 0.021") and solder termination specification. Both components are manufactured by TE Connectivity AMP Connectors under the same product category classification, ensuring design compatibility and assembly process alignment.

The Active product status of 1-5645947-6 provides assured long-term availability, documented manufacturing specifications, and compliance with current industry standards. This status transition does not introduce design modifications affecting electrical performance or mechanical fit within existing connector assemblies.

Export compliance classification (ECCN EAR99) remains consistent between both parts, maintaining regulatory compliance for international distribution and use.

Frequently Asked Questions (FAQ)

Q: Can 1-5645947-6 be used as a direct replacement for 1-645947-6 in existing designs?

A: Yes. Both terminals accept identical pin diameters (0.015" ~ 0.021") and utilize solder termination. The substitute part maintains functional compatibility with connector assemblies designed for the original part without requiring circuit board layout modification or connector interface redesign.

Q: What is the primary reason for substitution?

A: The original part 1-645947-6 carries Obsolete product status, limiting procurement availability. The substitute part 1-5645947-6 maintains identical electrical and mechanical specifications while providing Active product status and assured supply chain continuity.

Q: Are there differences in contact material or finish specifications?

A: Contact material and finish specifications are not provided for the substitute part 1-5645947-6 in the available documentation. Verification of these specifications with TE Connectivity AMP Connectors is necessary if contact material composition or finish thickness are critical design parameters.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: (1) Pin diameter acceptance range of 0.015" ~ 0.021", (2) Solder termination type, and (3) Pin receptacle terminal category. These parameters ensure mechanical fit and electrical connection within connector assemblies.

Q: Are both parts subject to the same export regulations?

A: Yes. Both 1-645947-6 and 1-5645947-6 carry identical ECCN classification (EAR99), maintaining consistent export compliance requirements across applications and distribution channels.

Q: What inventory status should be considered for procurement planning?

A: The original part 1-645947-6 shows 755 pieces in stock as new original inventory. The substitute part 1-5645947-6 shows 886 pieces in stock. However, procurement decisions should prioritize the Active status substitute part for new designs and long-term supply assurance, reserving original stock for legacy system support only.
