Engineering Selection Recommendations

TE Connectivity 3-647648-7 (Primary Part)

The TE Connectivity AMP Connectors 3-647648-7 maintains Active product status with full RoHS compliance and UL94 V-0 flammability rating. This part is suitable for applications requiring the highest flammability standards and is recommended for new designs where TE Connectivity supply chain integration is preferred.

Molex 0026604070 (Substitute - Tin Finish)

The Molex 0026604070 provides direct functional equivalence with identical pitch, position count, and mounting characteristics. This part carries ROHS3 compliance and UL94 V-0 rating, matching the primary part's regulatory profile. The tin contact finish on both mating and post surfaces aligns with standard industrial applications. This substitute is suitable for general purpose and industrial environments with equivalent performance expectations.

Molex 0026614070 (Substitute - Gold Finish)

The Molex 0026614070 offers the same core connector architecture as the 0026604070 with enhanced contact durability through gold mating surface finish (20.0µin / 0.51µm). This variant maintains ROHS3 compliance and UL94 V-0 rating. The gold finish provides improved corrosion resistance and is recommended for applications subject to environmental exposure or extended service life requirements.

Molex 1718130007 (Substitute - Nylon Insulation)

The Molex 1718130007 shares the same pitch, position count, and mounting configuration with polyamide (PA) nylon insulation material matching the primary part. This connector carries ROHS3 compliance but features UL94 V-2 flammability rating, which is lower than the primary part's V-0 rating. This substitute is suitable for general purpose and industrial applications where V-2 flammability performance is acceptable. The shorter post length (0.093" vs. 0.125") requires verification for specific PCB thickness and assembly requirements.

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity and REACH Unaffected status, ensuring compatibility with standard storage and handling protocols.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a connector can substitute for the TE Connectivity 3-647648-7?

A: The primary matching criteria include 0.156" (3.96mm) pitch, 7 positions in a single row, header connector type with male pin contacts, through-hole mounting, solder termination, friction lock fastening, and single-wall shrouding. All substitute parts listed meet these specifications.

Q: Can the Molex 1718130007 be used in applications requiring UL94 V-0 flammability rating?

A: No. The Molex 1718130007 carries a UL94 V-2 flammability rating, which is lower than the UL94 V-0 rating of the primary TE Connectivity part. Applications with specific V-0 requirements must use either the primary part or the Molex 0026604070 or 0026614070 substitutes.

Q: What is the difference between the Molex 0026604070 and 0026614070?

A: Both parts share identical connector architecture, pitch, position count, and mounting characteristics. The primary difference is the contact finish on the mating surface: the 0026604070 features tin finish (60.0µin / 1.52µm), while the 0026614070 features gold finish (20.0µin / 0.51µm). The gold finish provides enhanced corrosion resistance for applications requiring extended environmental durability.

Q: Are there dimensional differences between the primary part and substitute parts?

A: Yes. The insulation height varies: the TE Connectivity 3-647648-7 has 0.545" (13.84mm) insulation height, while all Molex substitutes have 0.446" (11.33mm). Additionally, the Molex 1718130007 has a shorter post length (0.093" vs. 0.125" on the primary part). These dimensional variations require verification against specific PCB thickness and assembly specifications before implementation.

Q: Are all substitute parts RoHS compliant?

A: Yes. The TE Connectivity 3-647648-7 is RoHS Compliant, and all three Molex substitutes carry ROHS3 Compliant status. All parts maintain REACH Unaffected status and EAR99 export classification.

Q: What is the inventory availability for each part?

A: The TE Connectivity 3-647648-7 has 790 pieces in stock. Among substitutes, the Molex 0026604070 has the highest availability at 39,397 pieces, followed by the Molex 1718130007 at 5,531 pieces, and the Molex 0026614070 at 1,169 pieces.

Q: Can the contact shape difference (circular vs. square) affect compatibility?

A: The TE Connectivity 3-647648-7 features circular contact shape, while all Molex substitutes feature square contact shape. Both shapes are mechanically compatible within the 0.156" (3.96mm) pitch standard and do not prevent functional substitution. Contact shape selection depends on specific mating connector requirements and application design parameters.

Q: What packaging format is available for these parts?

A: The TE Connectivity 3-647648-7 packaging specification is not provided. All Molex substitute parts are supplied in Bulk packaging format.
