TE Connectivity AMP Connectors 647126-5 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 647126-5 is a rectangular connector header designed for through-hole, right-angle mounting applications. This connector features a 5-position configuration with 0.156" (3.96mm) pitch spacing, suitable for board-to-cable/wire connections in general purpose and industrial applications. The part operates across a temperature range of -55°C to 105°C with a 600VAC voltage rating.

The 647126-5 carries an obsolete product status, which necessitates identification of active equivalent components for new designs and ongoing production requirements. Substitute parts maintain functional compatibility while offering improved availability and compliance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 647126-5 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (5)
• Pitch spacing (0.156" / 3.96mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Contact dimensions (Mating length 0.300", Post length 0.125")
• Insulation height (0.455")

Electrical Compatibility:

• Operating temperature range (-55°C ~ 105°C)
• Voltage rating (600VAC)
• Material flammability rating (UL94 V-0)

Functional Compatibility:

• Termination method (Solder)
• Fastening type (Friction Lock)
• Style (Board to Cable/Wire)
• Contact material (Copper Alloy)
• Insulation material (Thermoplastic, Glass Filled)

Substitute parts must maintain all specified dimensions, electrical ratings, and material properties. Variations in contact finish composition and product compliance status do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The 2-647126-5 serves as the direct functional equivalent to the obsolete 647126-5. Both components share identical mechanical and electrical specifications across all critical parameters including connector configuration, contact dimensions, operating temperature range, and voltage rating.

Product Status Consideration: The 647126-5 is classified as obsolete, while the 2-647126-5 maintains active product status. For new designs and ongoing production, the 2-647126-5 is the appropriate selection to ensure long-term component availability and supply chain continuity.

Compliance Consideration: The 2-647126-5 achieves ROHS3 compliance, whereas the 647126-5 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the 2-647126-5 is the required selection.

Contact Finish Consideration: The primary difference between these components is the contact finish composition. The 647126-5 features Tin-Lead plating, while the 2-647126-5 uses Tin plating. Both finishes provide equivalent electrical performance and corrosion resistance for the specified operating conditions. The Tin finish in the 2-647126-5 aligns with lead-free manufacturing standards.

Inventory Availability: The 2-647126-5 maintains higher inventory levels (1039 pieces) compared to the 647126-5 (770 pieces), supporting improved procurement timelines.

Frequently Asked Questions (FAQ)

Q: Can the 2-647126-5 directly replace the 647126-5 in existing applications?

A: Yes. The 2-647126-5 is mechanically and electrically identical to the 647126-5 across all functional parameters. Both components feature the same 5-position, 0.156" pitch configuration, through-hole right-angle mounting, contact dimensions, operating temperature range, and voltage rating. Direct substitution is supported without circuit or mechanical redesign.

Q: What is the significance of the contact finish difference between Tin-Lead and Tin?

A: Both Tin-Lead and Tin finishes provide equivalent electrical conductivity and corrosion resistance for the specified operating conditions. The Tin finish in the 2-647126-5 represents a lead-free alternative that aligns with modern manufacturing standards and RoHS compliance requirements. No functional performance difference exists between these finishes for this connector application.

Q: Why is the 647126-5 listed as obsolete?

A: The 647126-5 has been superseded by the 2-647126-5, which offers improved compliance characteristics and lead-free contact finishing. TE Connectivity has transitioned this product line to the newer part number to support current regulatory requirements and manufacturing practices.

Q: Are there any dimensional differences between these connectors?

A: No. Both the 647126-5 and 2-647126-5 maintain identical dimensions across all specified parameters: contact lengths (0.300" mating, 0.125" post), insulation height (0.455"), and pitch spacing (0.156"). These components are mechanically interchangeable.

Q: What is the current availability status of the 647126-5?

A: The 647126-5 is classified as obsolete. While inventory may be available from existing stock (770 pieces reported), long-term availability is not assured. The 2-647126-5 is the active product with established supply chain support.

Q: Does the 2-647126-5 meet RoHS requirements?

A: Yes. The 2-647126-5 is ROHS3 compliant. The 647126-5 is RoHS non-compliant. For applications requiring RoHS compliance, the 2-647126-5 is the appropriate selection.

Q: Are both connectors suitable for the same temperature and voltage operating conditions?

A: Yes. Both components operate across the identical temperature range of -55°C to 105°C and support a 600VAC voltage rating. They are functionally equivalent for all specified electrical operating conditions.

Q: What applications are these connectors designed for?

A: Both the 647126-5 and 2-647126-5 are specified for general purpose and industrial applications requiring board-to-cable/wire connections with friction lock fastening and solder termination.
