Engineering Selection Recommendations

All identified substitute parts are active products with RoHS compliance status. The primary distinction between the main part and substitutes relates to material flammability rating and contact finish specifications.

Flammability Considerations: The TE Connectivity 3-647181-6 carries a UL94 V-0 rating, indicating superior flame resistance. Molex substitutes 0009652068, 1718130006, 1718131006, and 1718133006 carry UL94 V-2 ratings. The Molex 0026614060 matches the UL94 V-0 rating of the main part.

Contact Finish Specifications: The main part features tin-plated contacts with 150.0µin (3.81µm) thickness on both mating and post surfaces. Substitute parts vary in contact finish composition and thickness. Molex 0026614060 and 1718131006 feature gold-plated mating surfaces, while others maintain tin plating. These variations do not affect functional interchangeability in standard applications.

Compliance Status: All parts maintain MSL 1 (Unlimited) moisture sensitivity classification and are ECCN EAR99 classified. The main part status is RoHS Compliant, while all substitutes are ROHS3 Compliant, indicating equivalent or enhanced environmental compliance.

Packaging Considerations: The main part is supplied in Bulk packaging. Molex 1718133006 is supplied in Cut Tape (CT) packaging with Pick and Place features, suitable for automated assembly environments. Other substitutes are supplied in Bulk packaging.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the TE Connectivity 3-647181-6?

A: Functional substitution is determined by matching core parameters: 0.156" (3.96mm) pitch, 6 positions in a single row, header connector type with male pin contacts, through-hole mounting, solder termination, shrouded single-wall design, friction lock fastening, and square contact shape. All identified substitutes meet these criteria.

Q: Are there differences in contact length between the main part and substitutes?

A: Yes. The main part has a mating contact length of 0.450" (11.43mm) and post length of 0.125" (3.18mm). Substitutes vary: Molex 0009652068 has 0.419" mating and 0.142" post length; Molex 0026614060 has 0.450" mating and 0.140" post length; Molex 1718130006, 1718131006, and 1718133006 have 0.448" mating and 0.093" post length. These variations reflect different board thickness accommodations and do not prevent substitution in standard applications.

Q: What is the significance of the UL94 V-0 versus UL94 V-2 flammability ratings?

A: UL94 V-0 indicates superior flame resistance compared to UL94 V-2. The main part carries V-0 rating. If flammability rating is a design requirement, Molex 0026614060 is the only substitute matching this specification. Other substitutes carry V-2 ratings and should be selected only when V-2 compliance is acceptable for the application.

Q: Can I use Molex 1718133006 in automated assembly?

A: Yes. Molex 1718133006 is supplied in Cut Tape (CT) packaging with Pick and Place features, making it suitable for automated assembly processes. Other substitutes are supplied in Bulk packaging and are intended for manual assembly or bulk handling.

Q: Are all substitutes RoHS compliant?

A: Yes. The main part is RoHS Compliant, and all identified substitutes are ROHS3 Compliant. ROHS3 compliance represents equivalent or enhanced environmental compliance standards.

Q: What is the difference between tin and gold contact finishes?

A: Tin-plated contacts (main part and most substitutes) provide standard corrosion resistance and solderability. Gold-plated contacts (Molex 0026614060 and 1718131006) offer enhanced corrosion resistance and improved contact reliability in low-force mating applications. Selection depends on application requirements and environmental exposure.

Q: Do all substitutes have the same insulation material?

A: No. The main part uses Thermoplastic with glass filling. Molex substitutes use either Polyamide (PA66) Nylon 6/6, Polyester with glass filling, or Polyamide (PA) Nylon. These material variations do not affect functional interchangeability in standard applications but may influence thermal and chemical resistance characteristics.

Q: What is the operating temperature range for substitute parts?

A: Operating temperature specifications are not provided for Molex substitute parts in the available data. The main part operates from -55°C to 105°C. Verify operating temperature requirements with the Molex product documentation if temperature extremes are critical to the application.

Q: Are all parts available in stock?

A: Inventory levels vary. The main part has 1026 pieces in stock. Molex substitutes have varying availability: 0009652068 (43,475 pcs), 0026614060 (28,306 pcs), 1718130006 (8,244 pcs), 1718131006 (981 pcs), and 1718133006 (7,138 pcs). Confirm current inventory status for procurement planning.
