TE Connectivity 647479-5 MTA-156 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 647479-5 is a 5-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 18 AWG discrete or ribbon cable. This connector features gold-plated female socket contacts, orange housing, and a locking ramp fastening mechanism for free-hanging in-line applications. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, packaging preferences, or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 647479-5 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (5)
• Pitch specification (0.156" / 3.96mm)
• Cable termination method (IDC)
• Wire gauge compatibility (18 AWG)
• Contact finish material (Gold)

Mechanical Compatibility Parameters:

• Number of rows (1)
• Mounting configuration (Free Hanging In-Line)
• Fastening mechanism (Locking Ramp)
• Housing color (Orange)

Compliance Parameters:

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

The substitute part 3-647479-5 maintains identical electrical and mechanical specifications while differing in packaging configuration and contact finish thickness. Both parts share the same base product number (647479) and series designation (MTA-156), confirming functional interchangeability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the 647479-5 and 3-647479-5 are Active product status components manufactured by TE Connectivity AMP Connectors and maintain full compliance with RoHS and REACH regulations. The primary distinction between these parts is packaging configuration and contact finish thickness.

647479-5 Selection Criteria:

• Standard packaging requirement
• Contact finish thickness of 30.0µin (0.76µm)
• RoHS Compliant designation

3-647479-5 Selection Criteria:

• Bulk packaging requirement
• Contact finish thickness of 15.0µin (0.38µm)
• ROHS3 Compliant designation
• Higher inventory availability (914 pcs vs. 703 pcs)

Both parts satisfy identical electrical and mechanical interface requirements for 5-position MTA-156 series IDC receptacle applications with 18 AWG cable termination. Selection between these parts depends on packaging format preference and contact finish thickness specification for the application. Both maintain unlimited moisture sensitivity rating and are suitable for free-hanging in-line mounting configurations with locking ramp fastening.

Frequently Asked Questions (FAQ)

Q: Are the 647479-5 and 3-647479-5 electrically interchangeable?

A: Yes. Both parts are 5-position MTA-156 series receptacle connectors with identical pitch (0.156"), contact type (female socket), cable termination method (IDC), and wire gauge (18 AWG). They function identically in IDC connector applications.

Q: What is the difference in contact finish thickness between these parts?

A: The 647479-5 features 30.0µin (0.76µm) gold contact finish thickness, while the 3-647479-5 features 15.0µin (0.38µm) thickness. Both utilize gold plating on female socket contacts. The difference reflects manufacturing variation within acceptable specification ranges for the MTA-156 series.

Q: Can I use 3-647479-5 in place of 647479-5 in my assembly?

A: Yes, provided your application does not specify a minimum contact finish thickness requirement. The 3-647479-5 maintains all electrical and mechanical compatibility parameters. Verify contact finish thickness specification in your design documentation before substitution.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant designations?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current version of the directive. Both parts meet hazardous substance restrictions and are suitable for applications requiring RoHS compliance.

Q: Does packaging format affect connector performance?

A: No. The 647479-5 (standard packaging) and 3-647479-5 (bulk packaging) are functionally identical. Packaging format affects only handling, storage, and ordering quantities, not electrical or mechanical performance.

Q: Are both parts suitable for ribbon cable and discrete wire termination?

A: Yes. Both the 647479-5 and 3-647479-5 support IDC termination for discrete or ribbon cable at 18 AWG wire gauge.

Q: What is the locking ramp fastening mechanism?

A: The locking ramp is the fastening method used to secure the connector in free-hanging in-line applications. Both substitute parts utilize identical locking ramp fastening, ensuring mechanical compatibility.

Q: Do these connectors require any special handling for moisture sensitivity?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control measures are required during storage, handling, or assembly.
