Substitute Part Grouping Explanation

Substitute parts for the FLE-140-01-G-DV-A-P are qualified based on the following critical parameters that must match or be compatible:

Core Matching Parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 80
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Insulation Material: Liquid Crystal Polymer (LCP)
• Contact Shape: Square

The substitute parts identified (104652-8 and 5-104652-8) from TE Connectivity AMP Connectors meet all core matching parameters. Variations in contact finish thickness, insulation height, operating temperature range, and compliance certifications are secondary parameters that may influence selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

FLE-140-01-G-DV-A-P (Primary Part): This connector is ROHS3 compliant and maintains an operating temperature range of -55°C to 125°C. It features phosphor bronze contacts with gold plating on both mating and post surfaces. This part is suitable for applications requiring full RoHS3 compliance and extended low-temperature operation.

104652-8 (TE Connectivity): This substitute is RoHS non-compliant and operates within -65°C to 105°C. It features copper alloy contacts with tin-lead post finish. The higher gold plating thickness on mating contacts (30.0µin versus 10.0µin) provides enhanced durability. This part is applicable only in non-RoHS regulated applications or where RoHS exemptions are granted.

5-104652-8 (TE Connectivity): This substitute is ROHS3 compliant with an operating temperature range of -65°C to 105°C. It features copper alloy contacts with tin post finish. The higher gold plating thickness on mating contacts matches 104652-8. This part is suitable for RoHS3-compliant applications with lower temperature requirements than the primary part.

Selection between these parts depends on compliance requirements, operating temperature specifications, and contact material compatibility with the mating connector.

Frequently Asked Questions (FAQ)

Q: Can 104652-8 be used as a direct replacement for FLE-140-01-G-DV-A-P?

A: 104652-8 matches all core mechanical and electrical parameters but is RoHS non-compliant. It is suitable only for applications where RoHS compliance is not required or where exemptions apply. The operating temperature range is also narrower (-65°C to 105°C versus -55°C to 125°C).

Q: What is the difference between 104652-8 and 5-104652-8?

A: Both parts are mechanically and electrically identical. The primary difference is RoHS compliance status: 104652-8 is RoHS non-compliant, while 5-104652-8 is ROHS3 compliant. The contact post finish also differs (tin-lead versus tin). For new designs, 5-104652-8 is preferred due to RoHS3 compliance.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: The insulation height differs slightly: FLE-140-01-G-DV-A-P is 0.172" (4.37mm) while both TE Connectivity substitutes are 0.187" (4.75mm). This 0.015" (0.38mm) difference must be evaluated against PCB layout and mating connector specifications to ensure mechanical clearance.

Q: Does the contact material difference affect performance?

A: The primary part uses phosphor bronze contacts while substitutes use copper alloy. Both materials are suitable for the specified current rating (2A per contact). Contact finish thickness on mating surfaces is higher on substitutes (30.0µin versus 10.0µin), which may provide extended contact life in high-cycle applications.

Q: Which substitute should be selected for new designs?

A: For new designs requiring RoHS3 compliance, select 5-104652-8. Verify that the operating temperature range (-65°C to 105°C) meets application requirements and that the increased insulation height accommodates PCB layout constraints.
