Substitute Part Grouping Explanation

Substitution of the TE Connectivity 647168-6 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 3-647168-6 qualifies as a direct equivalent based on the following matching criteria:

Electrical Parameters:

  • Identical connector type (Header), contact type (Male Pin), and pitch spacing (0.100" / 2.54mm)
  • Matching voltage rating (250VAC) and current rating methodology (Varies by Wire Gauge)
  • Identical operating temperature range (-55°C ~ 105°C)

Mechanical Parameters:

  • Identical number of positions (6) and row configuration (1 row)
  • Matching mounting type (Surface Mount) and termination method (Solder)
  • Identical shrouding style (Shrouded - 1 Wall) and fastening type (Friction Lock)
  • Matching contact geometry: square contact shape, 0.290" (7.37mm) mating contact length, 0.347" (8.81mm) insulation height

Material & Compliance Parameters:

  • Identical insulation material (Polyamide PA46, Nylon 4/6) and color (Black)
  • Matching material flammability rating (UL94 V-0)
  • Identical contact material (Copper Alloy) and mating contact finish (Gold at 30.0µin / 0.76µm thickness)
  • Matching RoHS compliance status and MSL rating (1 - Unlimited)

The primary distinction between the main part and substitute is product status (obsolete versus active) and post-contact finish specification (Tin-Lead versus Tin).

Engineering Selection Recommendations

The TE Connectivity 3-647168-6 is the direct functional equivalent for the obsolete 647168-6 model. Both components are manufactured by TE Connectivity within the MTA-100 series and share identical electrical and mechanical specifications across all critical parameters.

For New Designs and Production: The 3-647168-6 is the appropriate selection. This part carries active product status, ensuring ongoing availability and manufacturing support. The component maintains full compliance with RoHS regulations and carries MSL 1 rating, indicating no moisture sensitivity constraints during storage and handling.

For Legacy System Support and Repairs: The 3-647168-6 provides direct substitution for the obsolete 647168-6. The single material difference—post-contact finish specification (Tin-Lead versus Tin)—does not affect functional compatibility or performance in board-to-cable/wire applications. Both finishes are compatible with standard solder reflow processes and provide equivalent electrical performance.

Compliance Considerations: Both parts satisfy UL94 V-0 flammability requirements and maintain identical operating temperature ranges (-55°C ~ 105°C) and voltage ratings (250VAC). The RoHS compliance status difference (ROHS3 Compliant versus RoHS Compliant) reflects regulatory evolution and does not indicate functional incompatibility.

Frequently Asked Questions (FAQ)

Q: Can the 3-647168-6 be used as a direct replacement for the 647168-6 in existing assemblies?

A: Yes. The 3-647168-6 is electrically and mechanically identical to the 647168-6 across all functional parameters. Both components feature identical pitch spacing (0.100" / 2.54mm), contact configuration (6-position, single-row male pins), mounting type (surface mount), and operating specifications (250VAC, -55°C ~ 105°C). The parts are interchangeable in all applications.

Q: What is the significance of the different post-contact finish specifications?

A: The main part specifies Tin-Lead post finish, while the substitute specifies Tin post finish. This difference reflects manufacturing process updates and regulatory compliance evolution. Both finishes are compatible with standard solder reflow processes and provide equivalent electrical performance in solder joint formation. The mating contact finish (Gold) remains identical in both parts, ensuring consistent connector performance.

Q: Why is the 647168-6 classified as obsolete?

A: Product obsolescence typically reflects manufacturer lifecycle decisions and the transition to updated part numbers. The 3-647168-6 represents the active equivalent within the same MTA-100 series, providing continued availability and manufacturing support for this connector configuration.
