Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 640388-3 are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 3
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 1 Wall
• Fastening Type: Friction Lock

Compliance Criteria:

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

The substitute parts listed below satisfy these core parameters and maintain compatibility with applications designed for the 640388-3. Variations in contact geometry, contact finish, insulation material, and contact length specifications are secondary parameters that may influence performance in specific applications but do not preclude functional substitution within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original TE Connectivity 640388-3 component. The Molex 0026482035 and Molex 0026503030 connectors are functionally equivalent based on core electrical and mechanical parameters: identical pitch spacing, position count, mounting methodology, and termination approach.

TE Connectivity 640388-3 is recommended for applications requiring the specified operating temperature range of -55°C to 105°C and 600VAC voltage rating, with copper alloy contacts and thermoplastic glass-filled insulation material.

Molex 0026482035 provides an alternative with all positions loaded, gold-plated mating contacts, and brass contact material. This variant is suitable for applications where enhanced contact durability and corrosion resistance are beneficial.

Molex 0026503030 is configured with 2 of 3 positions loaded and tin-plated contacts. This variant accommodates applications where partial position loading is acceptable and cost optimization is a consideration.

All three connectors share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, supporting consistent supply chain management across substitute selections.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0026482035 directly replace the TE Connectivity 640388-3?

A: The Molex 0026482035 satisfies all primary matching criteria: 0.156" (3.96mm) pitch, 3 positions, 1 row, through-hole solder termination, shrouded 1-wall design, and friction lock fastening. Both connectors are Active status and ROHS3 compliant. Differences in contact length, insulation height, contact shape, and contact finish are secondary parameters that do not prevent functional substitution in applications designed for the 640388-3.

Q: What is the significance of the "Number of Positions Loaded" parameter?

A: The TE Connectivity 640388-3 and Molex 0026482035 are configured with all 3 positions loaded, meaning all contact positions contain male pins. The Molex 0026503030 is configured with only 2 of 3 positions loaded. This parameter affects the connector's physical configuration and should be verified against application requirements before substitution.

Q: Are there operating temperature differences between the substitute parts?

A: The TE Connectivity 640388-3 specifies an operating temperature range of -55°C to 105°C. The Molex substitute parts (0026482035 and 0026503030) do not provide operating temperature specifications in the available data. Applications requiring confirmed temperature performance should reference the original TE Connectivity specification.

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

A: The TE Connectivity 640388-3 features tin-plated mating contacts. The Molex 0026482035 features gold-plated mating contacts (20.0µin thickness), which provide enhanced corrosion resistance and contact reliability in demanding environments. The Molex 0026503030 features tin-plated mating contacts, matching the original specification.

Q: Do all substitute parts meet the same voltage and flammability requirements?

A: The TE Connectivity 640388-3 specifies 600VAC voltage rating and UL94 V-0 flammability rating. The Molex substitute parts do not provide voltage rating specifications but both are rated UL94 V-0. Applications requiring confirmed voltage performance should reference the original TE Connectivity specification or contact the Molex technical documentation.

Q: What is the difference between circular and square contact shapes?

A: The TE Connectivity 640388-3 features circular contact geometry, while both Molex substitutes feature square contact geometry. Contact shape affects mating force, contact pressure distribution, and compatibility with mating connectors. Applications must verify that mating connector receptacles are compatible with the selected contact shape.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The TE Connectivity 640388-3, Molex 0026482035, and Molex 0026503030 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), supporting use in regulated and commercial applications without additional handling restrictions.
