TE Connectivity AMP Connectors 647648-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 647648-7 is a rectangular connector header designed for through-hole mounting applications. This connector features a vertical orientation with 7 positions at 0.156" (3.96mm) pitch, shrouded design with single wall protection, and solder termination. The part is classified as Active product status and is suitable for general purpose and industrial applications requiring board-to-cable or board-to-board interconnection.

Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory constraints require component alternatives that maintain electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 647648-7 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 7
• Number of Rows: 1
• Pitch - Mating: 0.156" (3.96mm)
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 1 Wall
• Fastening Type: Friction Lock

Secondary Compatibility Criteria:

• Material Flammability Rating: UL94 V-0 or equivalent
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in contact finish, contact shape, insulation material, and contact length dimensions are secondary considerations that do not prevent functional substitution when mating interface requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Molex 0026604070

The Molex 0026604070 is the preferred substitute for the TE Connectivity 647648-7. This part maintains all critical electrical and mechanical parameters including connector type, contact configuration, pitch, mounting method, and termination. Both parts are Active product status with ROHS3 compliance and MSL 1 rating. The Molex 0026604070 features UL94 V-0 flammability rating matching the original specification. Contact finish differences (Tin versus Tin-Lead) do not affect functional compatibility in standard applications. The Molex part is available in high inventory quantity (39,397 pieces).

Secondary Substitute: Molex 0026614070

The Molex 0026614070 provides an alternative with gold-plated mating contacts. This part meets all core compatibility criteria and maintains Active product status with ROHS3 compliance. The gold contact finish provides enhanced corrosion resistance in applications requiring extended environmental exposure. Material flammability rating is UL94 V-0. This option is suitable when superior contact reliability is required. Inventory availability is lower (1,169 pieces) compared to the primary substitute.

Tertiary Substitute: Molex 1718130007

The Molex 1718130007 is functionally compatible with the TE Connectivity 647648-7 for core mating interface requirements. This part maintains the 7-position, 0.156" pitch configuration with through-hole solder termination and friction lock fastening. However, the material flammability rating is UL94 V-2, which differs from the original UL94 V-0 specification. This part is suitable for applications where the lower flammability rating is acceptable. All parts maintain ROHS3 compliance and MSL 1 rating. Inventory availability is moderate (5,531 pieces).

Frequently Asked Questions (FAQ)

Q: Can Molex 0026604070 be used as a direct replacement for TE Connectivity 647648-7?

A: Yes. The Molex 0026604070 maintains all critical electrical and mechanical parameters required for functional compatibility. Both parts feature 7 positions at 0.156" pitch, through-hole solder termination, shrouded single-wall design, and friction lock fastening. Contact finish differences do not prevent substitution in standard applications.

Q: What is the difference between the three Molex substitute options?

A: The primary differences are contact finish and flammability rating. Molex 0026604070 features tin-plated contacts with UL94 V-0 rating. Molex 0026614070 features gold-plated mating contacts with UL94 V-0 rating, providing enhanced corrosion resistance. Molex 1718130007 features tin-plated contacts with UL94 V-2 rating. All three maintain the same core connector configuration and pitch.

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

A: Yes. Contact length and insulation height vary among the parts. The TE Connectivity 647648-7 has an insulation height of 0.545" (13.84mm), while all Molex substitutes have 0.446" (11.33mm). Contact post lengths also differ: TE Connectivity is 0.125" (3.18mm), Molex 0026604070 and 0026614070 are 0.140" (3.56mm), and Molex 1718130007 is 0.093" (2.35mm). These dimensional variations do not affect mating interface compatibility but should be considered for PCB layout and mechanical clearance.

Q: Which substitute should be selected for high-reliability applications?

A: The Molex 0026614070 with gold-plated mating contacts is recommended for high-reliability applications. Gold plating provides superior corrosion resistance and contact stability over extended operational life. This part maintains UL94 V-0 flammability rating and ROHS3 compliance.

Q: Are all substitute parts RoHS compliant?

A: Yes. All identified substitute parts are ROHS3 compliant. The original TE Connectivity 647648-7 is also ROHS3 compliant. All parts maintain Moisture Sensitivity Level 1 (Unlimited).

Q: What is the significance of the UL94 V-2 rating on Molex 1718130007?

A: UL94 V-2 indicates the insulation material meets a lower flammability standard compared to UL94 V-0. The V-2 rating allows for dripping of burning particles, while V-0 does not. Selection of this part should be based on application-specific flammability requirements.

Q: Can these connectors be used interchangeably in existing designs?

A: The connectors are mechanically and electrically compatible at the mating interface due to identical pitch and contact configuration. However, dimensional differences in contact length and insulation height may require verification of PCB layout and mechanical clearance in existing designs before implementation.

Q: What is the contact shape difference between the original and substitutes?

A: The TE Connectivity 647648-7 features circular contact shapes, while all Molex substitutes feature square contact shapes. Both geometries are compatible with standard 0.156" pitch receptacles and do not affect functional performance.
