TE Connectivity 647477-2 MTA-100 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 647477-2 is a 2-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features gold-plated female socket contacts, a locking ramp fastening mechanism, and feed-through capability in a free-hanging inline or right-angle mounting configuration.

The 647477-2 carries an obsolete product status. Identification of equivalent and substitute components is necessary to support legacy system maintenance, repair, and continued field deployment where original inventory is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 647477-2 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (2)
• Pitch (0.100" / 2.54mm)
• Wire gauge compatibility (22 AWG)
• Cable termination method (IDC)
• Contact finish and thickness (Gold, 15.0µin)

Mechanical Parameters:

• Series designation (MTA-100)
• Mounting configuration (Free Hanging, In-Line, Right Angle)
• Fastening mechanism (Locking Ramp)
• Feed-through capability
• Physical color (Red)

Compliance Parameters:

• RoHS compliance status
• Moisture sensitivity level (MSL 1)

The substitute part 3-647477-2 satisfies all substitution criteria through complete parameter alignment with the main part, with the distinction of active product status and bulk packaging availability.

Parameter Comparison

Engineering Selection Recommendations

The 3-647477-2 is a direct functional equivalent to the 647477-2 across all electrical, mechanical, and compliance specifications. The primary distinction is product lifecycle status: the 647477-2 is obsolete while the 3-647477-2 maintains active status with TE Connectivity.

For applications requiring the MTA-100 2-position receptacle connector with IDC termination for 22 AWG cable, the 3-647477-2 provides equivalent performance and compatibility. Both parts share identical RoHS compliance and MSL ratings, ensuring suitability for equivalent environmental and regulatory applications.

The 3-647477-2 is available in bulk packaging with higher inventory levels (1146 pieces in stock versus 714 pieces for the 647477-2), supporting both immediate deployment and long-term supply chain requirements for legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the 3-647477-2 be used as a direct replacement for the 647477-2 in existing assemblies?

A: Yes. The 3-647477-2 is electrically and mechanically identical to the 647477-2. Both connectors feature the same 2-position MTA-100 receptacle configuration, IDC termination for 22 AWG cable, gold contact finish, locking ramp fastening, and feed-through capability. No design modifications are required.

Q: What is the significance of the different product status (Obsolete vs. Active)?

A: The 647477-2 is classified as obsolete, indicating TE Connectivity no longer manufactures this part number. The 3-647477-2 maintains active status, meaning it is currently produced and supported by the manufacturer. For new designs and ongoing supply requirements, the 3-647477-2 is the appropriate selection.

Q: Are there packaging differences between these two parts?

A: The 647477-2 packaging specification is not provided in the technical data. The 3-647477-2 is supplied in bulk packaging. Both parts are functionally identical; packaging differences do not affect electrical or mechanical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 647477-2 and 3-647477-2 are RoHS compliant and carry MSL rating 1 (Unlimited moisture sensitivity level). They are suitable for equivalent regulatory and environmental applications.

Q: What wire gauges are compatible with these connectors?

A: Both connectors are specified for 22 AWG wire. They accept discrete or ribbon cable with IDC termination. Wire gauge compatibility is identical between the two parts.

Q: Is the contact finish specification the same for both parts?

A: Yes. Both connectors feature gold-plated contacts with a finish thickness of 15.0µin (0.38µm), ensuring equivalent electrical performance and corrosion resistance.
