TE Connectivity 647000-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 647000-8 is an 8-position rectangular plug connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features tin-plated male pins, a closed-end design, and latch holder fastening for free-hanging or right-angle mounting configurations.

The 647000-8 is classified as obsolete. Locating active production equivalents is necessary to ensure continued component availability, supply chain reliability, and access to current manufacturing quality assurance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 647000-8 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

Electrical Parameters:

• 8-position configuration
• 0.100" (2.54mm) pitch spacing
• Single-row layout
• Male pin contact type
• IDC termination method
• 22 AWG wire gauge compatibility
• Tin contact finish with 80.0µin thickness

Mechanical Parameters:

• Free-hanging and right-angle mounting capability
• Latch holder fastening mechanism
• Closed-end connector design
• Compatibility with discrete or ribbon cable

Compliance Parameters:

• RoHS compliance
• MSL 1 rating
• EAR99 export classification

The substitute part 3-647000-8 satisfies all these requirements while offering the additional advantage of active product status and higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The 3-647000-8 is the direct functional equivalent of the 647000-8 and is suitable for all applications requiring an 8-position MTA-100 series IDC plug connector with 22 AWG wire compatibility.

Selection Basis:

The 3-647000-8 maintains complete electrical and mechanical equivalence with the obsolete 647000-8 across all specified parameters. Both connectors are RoHS compliant, carry MSL 1 ratings, and are classified under EAR99 export controls.

The primary distinction is product status: the 3-647000-8 is actively manufactured, ensuring access to current production batches, consistent quality assurance protocols, and long-term supply chain continuity. The 3-647000-8 is available in bulk packaging and maintains significantly higher inventory levels (2335 units versus 807 units).

For new designs, repair operations, or replacement applications, the 3-647000-8 is the appropriate selection. Existing stock of the 647000-8 may be utilized where immediately available, provided that connector specifications remain unchanged in the application.

Frequently Asked Questions (FAQ)

Q: Can the 3-647000-8 be used as a direct replacement for the 647000-8?

A: Yes. The 3-647000-8 is electrically and mechanically identical to the 647000-8. All electrical parameters, mechanical dimensions, contact specifications, and compliance certifications are equivalent. The connectors are interchangeable in all applications.

Q: What is the difference between the two part numbers?

A: The 647000-8 and 3-647000-8 are the same connector design from TE Connectivity AMP Connectors. The primary differences are product status (obsolete versus active) and packaging format. The 3-647000-8 is the current production equivalent.

Q: Are there any compatibility concerns when substituting the 3-647000-8 for the 647000-8?

A: No compatibility concerns exist. Both connectors feature identical pitch spacing (0.100"), contact configuration (8-position male pin), termination method (IDC), wire gauge rating (22 AWG), and mounting options (free-hanging and right-angle). They are fully compatible with the same mating receptacles and cable assemblies.

Q: What is the significance of the packaging difference?

A: The 647000-8 packaging is not specified in available documentation. The 3-647000-8 is supplied in bulk packaging. This distinction affects inventory management and order quantities but does not impact connector performance or electrical characteristics.

Q: Why is the 647000-8 classified as obsolete?

A: The 647000-8 has been superseded by the 3-647000-8 in TE Connectivity's active product portfolio. The 3-647000-8 represents the current manufacturing standard for this connector configuration.

Q: Can I use the 3-647000-8 in legacy equipment designed for the 647000-8?

A: Yes. The 3-647000-8 is fully compatible with all equipment and applications originally designed for the 647000-8. No modifications or adaptations are required.

Q: What certifications apply to both connectors?

A: Both the 647000-8 and 3-647000-8 are RoHS compliant, carry MSL 1 (Unlimited) moisture sensitivity ratings, and are classified as EAR99 for export purposes. The 3-647000-8 is additionally designated as REACH Unaffected.
