TE Connectivity 647000-3 MTA-100 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 647000-3 is a 3-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-lead contact finish, closed-end design, and latch holder fastening. The part is active in production with RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within the MTA-100 connector family.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the MTA-100 rectangular connector family is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector series (MTA-100)
• Connector type (Plug)
• Number of positions (3)
• Contact type (Male Pin)
• Pitch (0.100" / 2.54mm)
• Number of rows (1)
• Cable termination method (IDC)
• Wire gauge (22 AWG)
• Mounting type (Free Hanging, In-Line, Right Angle)
• Fastening type (Latch Holder)
• Contact finish thickness (80.0µin / 2.03µm)
• Features (Closed End)
• RoHS compliance status

Allowable Variation:

• Contact finish material (Tin-Lead vs. Tin) within the same thickness specification
• Inventory availability and packaging format (Bulk)
• REACH compliance status (when not conflicting with RoHS)

The substitute part 3-647000-3 maintains full electrical and mechanical compatibility with the main part 647000-3 through identical specifications across all critical parameters except contact finish composition, which remains within acceptable tin-based plating standards.

Parameter Comparison

Engineering Selection Recommendations

Both the main part 647000-3 and substitute part 3-647000-3 are active production components from TE Connectivity AMP Connectors with full RoHS compliance and unlimited moisture sensitivity rating. Selection between these parts is based on the following criteria:

647000-3 (Tin-Lead Contact Finish):

• Specified when tin-lead plating is explicitly required by design or legacy system compatibility
• Current inventory: 1,090 pieces
• REACH status: Vendor Undefined

3-647000-3 (Tin Contact Finish):

• Specified when tin-only plating meets design requirements
• Provides higher inventory availability: 33,763 pieces
• REACH status: REACH Unaffected
• Functionally equivalent within MTA-100 series specifications

Both parts maintain identical electrical performance, mechanical fit, and environmental compliance. The contact finish difference (tin-lead vs. tin) does not affect connector function when both are specified at the same 80.0µin (2.03µm) thickness. Selection should be based on design documentation requirements and inventory availability.

Frequently Asked Questions (FAQ)

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

A: Yes. Both connectors are electrically and mechanically equivalent within the MTA-100 series. The primary difference is contact finish material (tin vs. tin-lead), both applied at identical thickness (80.0µin). Both parts are RoHS compliant and carry MSL 1 rating.

Q: What is the significance of the contact finish difference between these parts?

A: The contact finish (tin-lead vs. tin) is a material composition difference applied at the same thickness specification. Both finishes provide equivalent electrical conductivity and contact reliability within the MTA-100 connector family. Selection depends on design specification requirements.

Q: Are these connectors compatible with MTA-100 series receptacles?

A: Yes. Both 647000-3 and 3-647000-3 are MTA-100 series plugs with 3 positions, 0.100" pitch, and male pin contacts. They interface with standard MTA-100 series receptacles.

Q: What cable types are compatible with these connectors?

A: Both connectors support IDC termination with discrete or ribbon cable at 22 AWG wire gauge.

Q: Are there any environmental or compliance differences between these parts?

A: Both parts are RoHS compliant with MSL 1 (unlimited moisture sensitivity). The substitute part 3-647000-3 carries REACH Unaffected status, while the main part 647000-3 has Vendor Undefined REACH status. Both are classified under ECCN EAR99 and HTSUS 8536.69.8000.

Q: What is the pitch specification and why is it important?

A: Both connectors have 0.100" (2.54mm) pitch, which defines the center-to-center spacing between contact positions. This specification ensures mechanical and electrical compatibility within the MTA-100 series.

Q: Can these connectors be used in right-angle or in-line mounting configurations?

A: Yes. Both connectors support free hanging mounting in both in-line and right-angle orientations.
