TE Connectivity AMP Connectors 796417-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 796417-8 is an 8-position wire-to-board terminal block designed for vertical mounting with through-hole PCB installation. This component features a 0.138" (3.50mm) pitch and operates within a 250 V, 7 A electrical specification range. The part belongs to the Buchanan series and utilizes screw-leaf spring wire termination with integrated wire guard protection.

The 796417-8 is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement. Substitute components must maintain electrical performance, mechanical compatibility, and PCB mounting characteristics while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 796417-8 is based on strict equivalence across the following critical parameters:

Electrical Compatibility: Current rating (7 A), voltage rating (250 V), and wire gauge acceptance (18-26 AWG) must remain identical to ensure safe operation within the original circuit design.

Mechanical Compatibility: The 8-position configuration, 0.138" (3.50mm) pitch, vertical-with-board mating orientation, and through-hole mounting type must be preserved to maintain PCB layout compatibility and connector alignment.

Thermal Performance: Operating temperature range of -55°C to 105°C must be maintained for environmental consistency.

Fastening Specifications: Screw thread type (M2.6) and torque specification (0.4 Nm) ensure proper wire termination and mechanical integrity.

The substitute part 1776253-8 satisfies all these critical parameters while offering improved product status and compliance certifications. Variations in wire termination method (rising cage clamp versus leaf spring with wire guard), housing material composition, and contact plating specifications do not affect functional substitution when electrical and mechanical parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 1776253-8 serves as a direct functional substitute for the obsolete 796417-8 based on complete electrical and mechanical parameter equivalence. All critical specifications—position count, pitch, voltage, current, wire gauge, temperature range, and fastening requirements—are identical between the two components.

Selection of the 1776253-8 is supported by the following engineering considerations:

Product Status: The 1776253-8 maintains active product status, ensuring long-term availability and supply chain continuity. The 796417-8 obsolete classification creates procurement risk and limits design support options.

Regulatory Compliance: The 1776253-8 is RoHS compliant and REACH affected, meeting current environmental and regulatory requirements. The 796417-8 non-compliant status may restrict use in applications subject to RoHS directives or regional environmental regulations.

Material Specifications: Both components utilize equivalent housing materials (polyamide/nylon) and brass contact materials with tin plating. The 1776253-8 housing material (PA66) and contact plating (tin) provide equivalent electrical and thermal performance to the original specification.

Wire Termination: The rising cage clamp termination method in the 1776253-8 provides functionally equivalent wire retention and electrical connection compared to the leaf spring with wire guard design of the 796417-8. Both methods achieve the specified 0.4 Nm torque and M2.6 screw thread requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1776253-8 be used as a direct replacement for the 796417-8 in existing PCB designs?

A: Yes. The 1776253-8 maintains identical pitch (0.138"), position count (8), mounting type (through-hole), and mating orientation (vertical with board). PCB footprints and hole patterns are compatible without modification.

Q: Are the electrical specifications identical between these components?

A: Yes. Both components are rated for 7 A current, 250 V voltage, and accept 18-26 AWG wire gauge. Operating temperature range (-55°C to 105°C) and screw specifications (M2.6 thread, 0.4 Nm torque) are identical.

Q: What is the difference between the screw-leaf spring termination and the rising cage clamp termination?

A: Both termination methods achieve equivalent wire retention and electrical connection using the same screw thread and torque specification. The rising cage clamp design in the 1776253-8 provides an alternative mechanical approach while maintaining functional equivalence.

Q: Does the housing material difference (PA FR15 versus PA66) affect performance?

A: No. Both polyamide materials provide equivalent electrical insulation, thermal stability, and mechanical strength within the specified operating temperature range (-55°C to 105°C). The PA66 material in the 1776253-8 is a standard engineering polymer for terminal block applications.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance ensures the component meets environmental regulations restricting hazardous substances. The 1776253-8 RoHS compliant status supports regulatory requirements in many markets and applications, whereas the 796417-8 non-compliant status may restrict use in regulated environments.

Q: Is the contact plating difference (copper-tin versus tin) significant?

A: No. Both plating specifications provide equivalent electrical conductivity and corrosion resistance. Tin plating in the 1776253-8 is a standard specification for brass contacts in terminal block applications.

Q: What is the packaging difference between these components?

A: The 796417-8 packaging specification is not provided. The 1776253-8 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Are there any application restrictions when substituting the 1776253-8 for the 796417-8?

A: No. The 1776253-8 meets or exceeds all electrical, mechanical, and environmental specifications of the 796417-8. Substitution is appropriate for all applications within the specified voltage (250 V), current (7 A), and temperature (-55°C to 105°C) parameters.
