TE Connectivity AMP Connectors 647143-5 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 647143-5 is a rectangular connector header designed for through-hole mounting applications. This connector features a vertical orientation with 5 positions at 0.156" (3.96mm) pitch, shrouded 4-wall construction, and solder termination. The part operates across an industrial temperature range of -55°C to 105°C with a 600VAC voltage rating.

The 647143-5 carries an obsolete product status, making identification of functionally equivalent alternatives necessary for ongoing design support, maintenance, and production continuity. Direct substitutes with active product status and improved compliance certifications are available within the MTA-156 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish functional interchangeability:

Primary Substitution Criteria:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (5)
• Pitch specification (0.156" / 3.96mm)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Friction Lock)
• Operating temperature range (-55°C ~ 105°C)
• Voltage rating (600VAC)
• Series designation (MTA-156)

All substitute parts identified in this reference maintain complete alignment with these parameters. Variations in contact finish specifications and RoHS compliance status do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 2-647143-5 serves as the direct functional equivalent to the obsolete 647143-5 within the MTA-156 series. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, mounting configuration, and operating ratings.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 647143-5 is classified as obsolete, while the 2-647143-5 maintains active product status with ROHS3 compliance certification. The main part carries RoHS non-compliant status.

The contact finish on the post differs between the two parts: the 647143-5 uses Tin-Lead, while the 2-647143-5 uses Tin. This difference reflects the transition to lead-free manufacturing standards and does not affect electrical or mechanical compatibility.

For new designs, maintenance applications, and production continuity, the 2-647143-5 is the appropriate selection. The active product status ensures ongoing availability and vendor support. For legacy system repairs requiring exact historical specification matching, the 647143-5 remains functionally equivalent where inventory permits.

Frequently Asked Questions (FAQ)

Q: Are the 647143-5 and 2-647143-5 electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including 600VAC voltage rating, operating temperature range of -55°C to 105°C, and contact material composition. The mating contact finish (gold) and thickness specifications are identical.

Q: What is the significance of the contact finish difference (Tin-Lead vs. Tin)?

A: The contact finish difference reflects manufacturing process evolution toward lead-free standards. The Tin finish on the 2-647143-5 post provides equivalent solderability and electrical performance. This change does not affect connector function or compatibility.

Q: Can the 2-647143-5 be used as a direct replacement in existing assemblies designed for the 647143-5?

A: Yes. The 2-647143-5 is mechanically and electrically equivalent. All dimensional specifications, mounting characteristics, and electrical ratings are identical. PCB layouts and mating connector designs require no modification.

Q: Why does the 647143-5 show obsolete status?

A: The 647143-5 has been superseded by the 2-647143-5 within the product lifecycle. The newer part number maintains all functional specifications while incorporating updated compliance certifications and manufacturing standards.

Q: What does ROHS3 compliance mean for the 2-647143-5?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. This certification supports environmental and regulatory requirements in many markets.

Q: Are there inventory considerations when selecting between these parts?

A: The 647143-5 shows 995 pieces in stock, while the 2-647143-5 shows 1039 pieces in stock. Both maintain adequate inventory levels. Selection should prioritize the active product status of the 2-647143-5 for long-term supply chain stability.

Q: Do these connectors require any special handling or storage conditions?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without special moisture control measures. Standard component storage practices apply.

Q: What applications are these connectors suitable for?

A: Both parts are rated for general purpose and industrial applications. The 0.156" pitch, 5-position configuration, and 600VAC rating support standard industrial control, instrumentation, and general connectivity requirements.
