TE Connectivity AMP Connectors 1-650122-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1-650122-8 is a 64 Position Female Card Edge Connector designed for dual edge applications with 0.100" (2.54mm) pitch spacing. This connector features press-fit termination, gold-plated phosphor bronze contacts, and operates across a temperature range of -55°C to 85°C. The part is classified as obsolete, making identification of equivalent substitute components essential for ongoing system support and procurement planning. Substitute parts must maintain functional compatibility across critical electrical and mechanical parameters including position count, pitch spacing, card thickness tolerance, and contact finish specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-650122-8 is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 64
• Pitch: 0.100" (2.54mm)
• Gender: Female
• Card Type: Dual Edge
• Number of Rows: 2
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Mounting Type: Through Hole
• Termination: Press-Fit
• Color: Black

Allowable Variation Parameters:

• Card Thickness: Substitute must accommodate the original specification range of 0.054" ~ 0.071" (1.37mm ~ 1.80mm)
• Operating Temperature: Substitute operating range must encompass or exceed the original -55°C ~ 85°C specification
• Contact Material: Phosphor Bronze or Copper Alloy compositions are functionally equivalent for this application
• Product Status: Active status preferred for ongoing availability; obsolete status acceptable for legacy system support

The substitute part 745-064-520-201 meets all mandatory matching parameters and operates within acceptable variation tolerances.

Parameter Comparison

Engineering Selection Recommendations

The Mercury United Electronics 745-064-520-201 is a direct functional substitute for the obsolete TE Connectivity 1-650122-8. Both connectors share identical electrical and mechanical specifications across all critical parameters including position count, pitch, contact finish, and termination method.

Advantages of 745-064-520-201:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance provides regulatory advantage over the non-compliant original part
• Extended operating temperature range (-40°C ~ 105°C) exceeds the original specification (-55°C ~ 85°C)
• Card thickness tolerance (0.054" ~ 0.070") is compatible with the original specification range
• Copper Alloy contact material provides equivalent electrical performance to phosphor bronze

Compatibility Considerations:

• Card thickness tolerance variation of 0.001" (0.02mm) at the upper limit is within acceptable mechanical tolerance for press-fit applications
• Both parts utilize identical gold contact finish thickness (30.0µin / 0.76µm)
• Dual edge configuration and 64-position layout ensure direct mechanical fit in existing PCB edge slots

Selection of 745-064-520-201 is appropriate for new procurement, system redesigns, and legacy system support where the original 1-650122-8 is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the 745-064-520-201 be used as a direct replacement for the 1-650122-8 in existing designs?

A: Yes. The 745-064-520-201 meets all mandatory electrical and mechanical parameters. Both connectors feature 64 positions, 0.100" pitch, dual edge configuration, gold contact finish at 30.0µin thickness, and press-fit termination. The substitute operates across a wider temperature range and maintains compatible card thickness tolerances.

Q: What is the significance of the card thickness tolerance difference between the two parts?

A: The original 1-650122-8 specifies 0.054" ~ 0.071" (1.37mm ~ 1.80mm) card thickness, while the 745-064-520-201 specifies 0.054" ~ 0.070" (1.37mm ~ 1.78mm). The 0.001" (0.02mm) reduction at the upper limit is within standard mechanical tolerance for press-fit connector applications and does not affect functional compatibility.

Q: Does the contact material difference between phosphor bronze and copper alloy affect performance?

A: No. Both phosphor bronze and copper alloy are standard contact materials for gold-plated connectors in this application category. The 30.0µin gold finish thickness on both parts provides equivalent electrical conductivity and corrosion resistance.

Q: Why is the 745-064-520-201 marked as ROHS3 compliant while the original is not?

A: The 1-650122-8 is an obsolete part manufactured prior to widespread RoHS3 implementation. The 745-064-520-201 is an active product manufactured to current regulatory standards. ROHS3 compliance indicates the substitute meets current environmental and material restriction requirements.

Q: Is the extended operating temperature range of the 745-064-520-201 (-40°C ~ 105°C) a concern for applications requiring -55°C operation?

A: The substitute's lower temperature limit is -40°C, which does not meet the original -55°C specification. Applications requiring operation below -40°C must retain the original 1-650122-8 or identify alternative substitutes with matching low-temperature specifications.

Q: What packaging format is the 745-064-520-201 supplied in?

A: The 745-064-520-201 is supplied in bulk packaging. The original 1-650122-8 packaging format is not specified in available documentation.

Q: Are both connectors suitable for through-hole PCB assembly?

A: Yes. Both the 1-650122-8 and 745-064-520-201 utilize through-hole mounting with press-fit termination, making them suitable for standard PCB assembly processes.
