Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 3-647180-8 are identified based on the following critical parameters that determine functional equivalence:

Core Matching Criteria:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 8
• Number of Rows: 1
• Shrouding: Shrouded - 1 Wall
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Friction Lock
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The three Molex substitute parts (0026482085, 0026604080, 0026614080) satisfy all core matching criteria. Variations in contact finish material, contact length specifications, and insulation material composition do not prevent functional substitution in applications where the main part is specified, as these parameters remain within acceptable tolerance ranges for standard rectangular connector applications.

Parameter Comparison

Engineering Selection Recommendations

All three Molex substitute parts maintain Active product status and ROHS3 compliance, matching the regulatory and compliance profile of the TE Connectivity 3-647180-8. The substitute parts are suitable for applications requiring rectangular connector headers with 8-position, 0.156" pitch through-hole solder termination.

Molex 0026482085 features gold-plated mating contacts and brass contact material with breakaway connector capability, offering enhanced corrosion resistance in applications subject to environmental exposure or extended storage periods.

Molex 0026604080 and Molex 0026614080 share identical mechanical and electrical specifications, with the primary distinction being contact finish material. Part 0026604080 features tin-plated mating contacts, while part 0026614080 features gold-plated mating contacts. Both utilize polyester glass-filled insulation material.

Selection between substitute parts depends on application-specific requirements for contact finish durability, environmental conditions, and cost considerations. All substitute parts maintain compatibility with standard 0.156" pitch connector systems and through-hole PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can Molex 0026482085 be used as a direct replacement for TE Connectivity 3-647180-8?

A: Yes. Both parts share identical pitch spacing (0.156"), position count (8), mounting type (through-hole), termination method (solder), and shrouding configuration (shrouded 1-wall). The Molex part includes breakaway connector capability as an additional feature. Contact finish and material composition differences do not prevent functional substitution in standard rectangular connector applications.

Q: What is the difference between Molex 0026604080 and Molex 0026614080?

A: The primary difference is contact finish material. Part 0026604080 features tin-plated mating contacts, while part 0026614080 features gold-plated mating contacts. Both parts maintain identical mechanical dimensions, pitch spacing, position count, and mounting specifications. Selection depends on application requirements for contact durability and environmental resistance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The TE Connectivity 3-647180-8 and all three Molex substitute parts (0026482085, 0026604080, 0026614080) are ROHS3 compliant and carry MSL rating of 1 (Unlimited), indicating compatibility with standard manufacturing and storage conditions.

Q: Do the substitute parts support the same current and voltage ratings?

A: The TE Connectivity 3-647180-8 specifies 600VAC voltage rating and current rating that varies by wire gauge. The Molex substitute parts do not provide explicit voltage or current ratings in their specifications. For applications with specific voltage or current requirements, consult manufacturer datasheets to confirm suitability.

Q: What is the significance of the contact length variations between parts?

A: Contact length variations (post length ranging from 0.125" to 0.172") reflect design differences between manufacturers but do not prevent functional substitution. All parts maintain the same mating contact length (0.450") and overall contact length within acceptable tolerance ranges for standard 0.156" pitch connector systems.

Q: Can these parts be used interchangeably in automotive applications?

A: The Molex substitute parts list automotive applications in their specifications. The TE Connectivity 3-647180-8 specifies general purpose and industrial applications. For automotive-specific requirements, consult application engineering documentation to confirm suitability of the TE Connectivity part in automotive environments.
