TE Connectivity AMP Connectors 640384-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 640384-2 is an active rectangular connector header designed for through-hole mounting applications. This unshrouded, 2-position connector operates within the MTA-156 series and features male pin contacts with a 0.156" (3.96mm) pitch. The connector is rated for 600VAC operation across an extended temperature range of -55°C to 105°C, making it suitable for general purpose and industrial applications. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design requirements necessitate equivalent functionality with different mechanical or material specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 640384-2 is determined by the following critical parameters:

Primary Matching Criteria:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 2
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Operating Temperature Range: -55°C ~ 105°C
• Voltage Rating: 600VAC minimum
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The substitute part FWJ-02-01-T-S from Samtec Inc. meets all primary matching criteria. Variations in contact geometry (circular versus square), contact material composition (copper alloy versus phosphor bronze), insulation material (thermoplastic glass-filled versus polybutylene terephthalate), and contact dimensions represent acceptable engineering tolerances within the rectangular connector category. The substitute part provides equivalent electrical performance and mechanical compatibility for board-level interconnection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 640384-2 and Samtec FWJ-02-01-T-S connectors maintain active product status and full compliance with ROHS3 and UL94 V-0 flammability standards. The substitute part provides equivalent electrical performance across the specified voltage and temperature operating ranges. Selection between these parts should be based on:

Mechanical Compatibility: The substitute part exhibits longer overall contact length (0.750" versus 0.650") and extended post length (0.175" versus 0.125"), which may affect PCB layout and mating depth requirements. Verification of board-level clearances and connector cavity depth is necessary when transitioning between these parts.

Material Specifications: The substitute part utilizes phosphor bronze contacts and polybutylene terephthalate insulation, compared to copper alloy contacts and glass-filled thermoplastic in the primary part. Both material systems provide equivalent electrical performance and thermal stability within the specified operating range.

Regulatory Compliance: Both parts satisfy ROHS3 compliance and EAR99 export classification requirements. Moisture sensitivity levels are identical at MSL 1 (Unlimited), indicating no special handling or storage requirements.

Availability: Current inventory levels support both parts, with 1843 units of the primary part and 1757 units of the substitute part available in bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the Samtec FWJ-02-01-T-S directly replace the TE Connectivity 640384-2 in existing designs?

A: Direct replacement requires verification of PCB layout compatibility. The substitute part has longer contact dimensions (0.750" overall length versus 0.650"), which affects mating depth and board cavity specifications. Mechanical fit must be confirmed before implementation.

Q: Are there electrical performance differences between these connectors?

A: Both connectors operate at 600VAC minimum voltage rating and function across the identical -55°C to 105°C temperature range. The substitute part provides additional 845VDC rating capability. Electrical performance is equivalent for standard applications within the specified parameters.

Q: What are the material differences, and do they affect performance?

A: The primary part uses copper alloy contacts with glass-filled thermoplastic insulation. The substitute uses phosphor bronze contacts with polybutylene terephthalate insulation. Both material combinations provide equivalent electrical conductivity, thermal stability, and mechanical durability within the operating specifications.

Q: Do both connectors require the same mating components?

A: Both connectors feature identical 0.156" (3.96mm) pitch and 2-position configuration. However, the substitute part is specified for board-to-board style while the primary part is board-to-cable/wire style. Mating component compatibility depends on the specific application interface requirements.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant, UL94 V-0 rated, and classified as EAR99 for export purposes. Moisture sensitivity levels are identical at MSL 1 (Unlimited). No special handling or storage protocols are required for either part.

Q: What inventory considerations should be evaluated?

A: Both parts are available in bulk packaging with substantial inventory levels (1843 units for the primary part, 1757 units for the substitute). Lead time and supply chain continuity should be assessed based on current procurement requirements.
