TE Connectivity AMP Connectors 796417-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 796417-3 is a 3 Position Wire to Board Terminal Block designed for vertical mounting with through-hole PCB attachment. 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 796417-3 carries an Obsolete product status, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement. Direct substitutes maintain identical electrical ratings, mechanical dimensions, and mounting characteristics while offering improved product availability and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 796417-3 is determined by 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 unchanged.

Mechanical Compatibility: Position count (3), pitch spacing (0.138" / 3.50mm), mating orientation (vertical with board), and mounting method (through hole) must be identical.

Termination Interface: Screw thread specification (M2.6) and torque requirement (0.4 Nm) must match to ensure proper installation and performance.

Operating Environment: Temperature range (-55°C to 105°C) must be maintained.

The substitute part 1776253-3 satisfies all these criteria while offering improved product status and regulatory compliance. Both parts are members of the Buchanan terminal block series and maintain full dimensional and electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement: The 1776253-3 substitute part is the appropriate selection. This part maintains full electrical and mechanical compatibility with the 796417-3 while offering Active product status and ROHS3 compliance. The substitute eliminates obsolescence risk and aligns with current regulatory requirements.

For Existing Inventory Management: The 796417-3 remains functionally suitable for applications already in production where component qualification has been completed. However, transition planning to the 1776253-3 is recommended for long-term supply chain stability.

Compliance Considerations: The 1776253-3 provides ROHS3 compliance and defined REACH status, addressing regulatory requirements that may be mandated in target markets. The 796417-3 carries RoHS non-compliant status and undefined REACH status, which may restrict use in regulated applications.

Material and Termination Differences: While the 1776253-3 employs a rising cage clamp termination mechanism and PA66 housing material compared to the leaf spring termination and PA FR15 housing of the 796417-3, both designs maintain identical electrical performance and mechanical interchangeability within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can the 1776253-3 be used as a direct replacement for the 796417-3 in existing PCB designs?

A: Yes. Both parts maintain identical pitch spacing (0.138" / 3.50mm), through-hole mounting configuration, electrical ratings (7 A, 250 V), and wire gauge acceptance (18-26 AWG). PCB footprints and mounting hole patterns are compatible.

Q: What is the primary reason for substituting the 796417-3?

A: The 796417-3 carries Obsolete product status, which creates long-term supply chain risk. The 1776253-3 substitute maintains full functional equivalence while offering Active product status and improved regulatory compliance (ROHS3).

Q: Are there differences in wire termination between these parts?

A: Yes. The 796417-3 uses screw-leaf spring termination with wire guard, while the 1776253-3 uses screw-rising cage clamp termination. Both mechanisms operate at identical torque specification (0.4 Nm) and M2.6 screw thread, ensuring equivalent installation and performance.

Q: Do the housing material differences affect electrical performance?

A: No. The 796417-3 uses PA FR15 nylon while the 1776253-3 uses PA66 nylon. Both materials meet the operating temperature range (-55°C to 105°C) and maintain equivalent electrical insulation properties within the specified voltage rating (250 V).

Q: What is the inventory status for each part?

A: The 796417-3 has 903 pieces in stock (Obsolete status). The 1776253-3 has 826 pieces in stock (Active status). Active status indicates ongoing manufacturing support and future availability.

Q: Are there any restrictions on using the 796417-3 in new applications?

A: The 796417-3 is RoHS non-compliant with undefined REACH status. Applications subject to RoHS3 or REACH regulations should use the 1776253-3 substitute, which carries ROHS3 compliance and defined REACH status.

Q: Do both parts accept the same wire gauge range?

A: Yes. Both the 796417-3 and 1776253-3 accept wire gauges from 18 to 26 AWG, ensuring equivalent wire termination capability.

Q: What is the screw torque specification for installation?

A: Both parts require 0.4 Nm (3.5 Lb-In) torque on the M2.6 screw thread. Installation procedures are equivalent.
