TE Connectivity 647168-3 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 647168-3 is a surface mount rectangular connector header designed for board-to-cable/wire applications. This component is a shrouded, single-row, 3-position header with 0.100" (2.54mm) pitch spacing, commonly used in general-purpose electronic assemblies. The part is classified as obsolete, making identification of active equivalent components essential for ongoing production and maintenance applications. The substitute part 3-647168-3 provides functional continuity with active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution between 647168-3 and 3-647168-3 is valid based on identical electrical and mechanical parameters across all critical specifications. Both parts share the same base product number (647168), connector series (MTA-100), and functional characteristics. The substitution is determined by the following matching parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (3 positions, 1 row)
• Mating pitch specification (0.100" / 2.54mm)
• Mounting technology (Surface Mount)
• Shrouding design (Shrouded - 1 Wall)
• Termination method (Solder)
• Operating temperature range (-55°C ~ 105°C)
• Voltage rating (250VAC)
• Flammability compliance (UL94 V-0)
• Insulation material (Polyamide PA46, Nylon 4/6)
• Contact material and finish specifications

The primary distinction between these parts is product status and packaging configuration, not functional capability.

Parameter Comparison

Engineering Selection Recommendations

The part 3-647168-3 is the direct active equivalent of the obsolete 647168-3. Selection of 3-647168-3 is appropriate for all applications currently using or specifying 647168-3 due to complete functional and electrical equivalence.

The contact finish post specification differs between the two parts (Tin-Lead versus Tin). This difference reflects regulatory compliance evolution, specifically the transition to lead-free manufacturing standards. Both finishes are functionally compatible with standard solder assembly processes and provide equivalent electrical performance in the specified operating temperature range.

Both parts maintain identical RoHS compliance status and REACH unaffected designation. The active product status of 3-647168-3 ensures continued availability and supply chain reliability compared to the obsolete 647168-3.

Frequently Asked Questions (FAQ)

Q: Can 3-647168-3 be used as a direct replacement for 647168-3 in existing designs?

A: Yes. The parts are electrically and mechanically equivalent across all functional parameters. The connector type, position count, pitch, mounting method, operating temperature range, voltage rating, and all contact specifications are identical. The difference in contact post finish (Tin versus Tin-Lead) does not affect functional compatibility.

Q: What is the significance of the product status difference between these parts?

A: The 647168-3 is classified as obsolete, indicating it is no longer manufactured or supported by TE Connectivity. The 3-647168-3 is active, meaning it is currently produced and available through authorized distribution channels. For new designs and ongoing production, 3-647168-3 should be specified to ensure supply continuity.

Q: Are there packaging differences between 647168-3 and 3-647168-3?

A: The 647168-3 packaging specification is not provided in the technical data. The 3-647168-3 is supplied in bulk packaging. Packaging configuration does not affect the connector's electrical or mechanical performance, only the quantity and presentation format for procurement and assembly operations.

Q: Do both parts meet the same regulatory and compliance standards?

A: Both parts are UL94 V-0 flammability rated, RoHS compliant, REACH unaffected, and classified under ECCN EAR99. Both carry the same HTSUS code (8536.69.4040). The compliance profiles are equivalent for regulatory purposes.

Q: What is the difference between Tin-Lead and Tin contact post finishes?

A: Tin-Lead finish (647168-3) represents older manufacturing standards. Tin finish (3-647168-3) reflects current lead-free manufacturing compliance. Both finishes provide equivalent electrical conductivity and solder joint reliability. The Tin finish is the current standard for new production.

Q: Is the MTA-100 series designation the same for both parts?

A: Yes. Both parts belong to the TE Connectivity MTA-100 connector series. This series designation indicates compatibility with MTA-100 series mating connectors and accessories.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without special moisture control measures. These connectors do not require desiccant packaging or controlled storage conditions.
