TE Connectivity AMP Connectors 647079-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 647079-2 is a rectangular connector header designed for through-hole, right-angle mounting applications. This shrouded, single-wall 2-position connector operates at 0.100" (2.54mm) pitch and is classified as an active product. The connector accommodates board-to-cable/wire configurations with solder termination and friction lock fastening. Substitute parts are identified to address inventory availability, compliance requirements, and packaging preferences while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 647079-2 connector is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 2
• Number of Rows: 1
• Voltage Rating: 250VAC
• Operating Temperature Range: -55°C ~ 105°C
• Contact Type: Male Pin
• Contact Material: Copper Alloy

Mechanical Compatibility Parameters:

• Connector Type: Header
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 1 Wall
• Termination: Solder
• Fastening Type: Friction Lock
• Insulation Material: Polyamide (PA46), Nylon 4/6
• Material Flammability Rating: UL94 V-0

Allowable Variations:

• Contact Finish - Post: Tin-Lead or Tin (both acceptable for solder termination compatibility)
• Packaging configuration (bulk or box)
• RoHS and REACH compliance status (does not affect electrical or mechanical function)

The substitute part 3-647079-2 maintains full equivalence across all critical parameters with the exception of contact finish post material (Tin versus Tin-Lead) and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

647079-2 (Main Part): This part is suitable for applications where RoHS non-compliance is acceptable and REACH-affected material sourcing is permissible. The tin-lead contact finish post provides established solder compatibility. Product status is active with moderate inventory availability.

3-647079-2 (Substitute Part): This part is suitable for applications requiring RoHS compliance and REACH-unaffected material sourcing. The tin contact finish post is functionally equivalent for solder termination applications. Product status is active with significantly higher inventory availability (5048 units versus 712 units). The box packaging provides organized component handling compared to bulk packaging.

Selection Criteria:

• If regulatory compliance (RoHS/REACH) is a design requirement, select 3-647079-2
• If inventory availability is critical, select 3-647079-2
• If packaging preference is bulk format, select 647079-2
• If packaging preference is box format, select 3-647079-2
• Both parts are electrically and mechanically interchangeable for general-purpose board-to-cable/wire applications

Frequently Asked Questions (FAQ)

Q: Are the 647079-2 and 3-647079-2 connectors electrically interchangeable?

A: Yes. Both connectors operate at identical voltage ratings (250VAC), current ratings (varies by wire gauge), and temperature ranges (-55°C ~ 105°C). The mating pitch (0.100"/2.54mm), number of positions (2), contact type (male pin), and contact material (copper alloy) are identical across both parts.

Q: What is the difference between tin-lead and tin contact finish on the post?

A: Both tin-lead and tin contact finishes are suitable for solder termination applications. The 647079-2 features tin-lead post finish, while the 3-647079-2 features tin post finish. This difference does not affect electrical performance or solder joint reliability for general-purpose applications.

Q: Does RoHS compliance affect the connector's performance?

A: No. RoHS compliance is a regulatory and material sourcing designation. It does not alter the electrical characteristics, mechanical properties, or operating performance of the connector. The 3-647079-2 is RoHS compliant, while the 647079-2 is RoHS non-compliant. Selection depends on project regulatory requirements.

Q: What does REACH-affected versus REACH-unaffected mean?

A: REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) is a European Union chemical regulation. REACH-affected parts contain substances of concern requiring additional documentation and compliance measures. REACH-unaffected parts do not contain such substances. The 647079-2 is REACH-affected; the 3-647079-2 is REACH-unaffected. Selection depends on supply chain and regulatory requirements.

Q: Can I use the 3-647079-2 as a direct replacement for the 647079-2?

A: Yes, for electrical and mechanical applications. Both connectors are functionally equivalent across all critical parameters: pitch, position count, mounting type, shrouding, termination method, and fastening type. The primary differences are packaging format (bulk versus box), inventory availability, and regulatory compliance status.

Q: What is the difference between bulk and box packaging?

A: The 647079-2 is supplied in bulk packaging, while the 3-647079-2 is supplied in box packaging. Box packaging provides organized component storage and handling. Bulk packaging typically offers lower per-unit cost. Both packaging formats contain identical connector specifications.

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

A: Yes. Both the 647079-2 and 3-647079-2 are designed for through-hole, right-angle mounting with solder termination. The 0.140" (3.56mm) post length and square contact shape are identical across both parts, ensuring compatible PCB hole spacing and assembly procedures.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture-controlled storage or handling procedures prior to assembly.

Q: Which part should I select for new designs?

A: For new designs, the 3-647079-2 is recommended due to RoHS compliance, REACH-unaffected status, and significantly higher inventory availability (5048 units). This part meets modern regulatory requirements and provides supply chain stability. The 647079-2 remains suitable for legacy designs or applications where RoHS non-compliance is acceptable.
