Key Parameters

Substitute Part Grouping Explanation

Substitution of the 796417-2 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 identical to ensure safe operation within the original circuit design.

Mechanical Compatibility: Positions per level (2), pitch (0.138" / 3.50mm), mating orientation (vertical with board), and mounting type (through hole) must match to ensure physical fit on the PCB and connector interface compatibility.

Thermal Compatibility: Operating temperature range (-55°C ~ 105°C) must be maintained to support the intended application environment.

Fastening Compatibility: Screw thread specification (M2.6) and torque rating (0.4 Nm / 3.5 Lb-In) must be preserved to maintain proper wire termination and prevent over-torque or under-torque conditions.

The substitute part 1776253-2 meets all these critical parameters. Differences in wire termination method (screw-leaf spring with wire guard versus screw-rising cage clamp), housing material composition, contact plating, and regulatory compliance do not affect the core electrical and mechanical substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

The 1776253-2 serves as a direct functional substitute for the obsolete 796417-2 based on electrical and mechanical parameter equivalence. Both components share identical current, voltage, pitch, wire gauge, mounting configuration, and thermal operating range specifications.

Product Status Consideration: The 796417-2 is obsolete with limited inventory availability (781 pcs). The 1776253-2 is an active product with significantly higher inventory (9177 pcs), ensuring long-term supply chain reliability and component availability for production continuity.

Regulatory Compliance: The 1776253-2 is ROHS3 compliant and REACH affected, whereas the 796417-2 is RoHS non-compliant with undefined REACH status. For applications subject to environmental regulations or customer compliance requirements, the 1776253-2 provides superior regulatory alignment.

Material and Construction Differences: The 1776253-2 utilizes Polyamide PA66 (Nylon 6/6) housing compared to the PA FR15 (Nylon FR15) in the 796417-2. The wire termination method differs (rising cage clamp versus leaf spring with wire guard), and contact plating differs (tin plated versus copper tin plated). These differences do not affect electrical or mechanical compatibility within the specified parameter ranges.

Selection of the 1776253-2 is appropriate for new designs, production restocking, and legacy system support where component obsolescence necessitates substitution.

Frequently Asked Questions (FAQ)

Q: Can the 1776253-2 be used as a direct replacement for the 796417-2 in existing PCB designs?

A: Yes. The 1776253-2 is mechanically and electrically compatible with the 796417-2. Both components share identical pitch (0.138" / 3.50mm), through-hole mounting configuration, electrical ratings (7 A / 250 V), and wire gauge acceptance (18-26 AWG). PCB footprints designed for the 796417-2 accommodate the 1776253-2 without modification.

Q: What is the difference between the wire termination methods?

A: The 796417-2 uses screw-leaf spring termination with integrated wire guard. The 1776253-2 uses screw-rising cage clamp termination. Both methods employ M2.6 screws with 0.4 Nm (3.5 Lb-In) torque specification and accept identical wire gauges (18-26 AWG). The termination method difference does not affect electrical performance or mechanical fit.

Q: Are there packaging differences between these parts?

A: The 796417-2 packaging specification is not provided in the available data. The 1776253-2 is supplied in bulk packaging. Confirm packaging requirements with your procurement specification before ordering.

Q: Why is the 1776253-2 preferred over the 796417-2?

A: The 796417-2 is obsolete with limited inventory (781 pcs). The 1776253-2 is an active product with substantially higher inventory availability (9177 pcs), ensuring reliable supply for production. Additionally, the 1776253-2 is ROHS3 compliant and REACH affected, providing superior regulatory compliance for applications subject to environmental standards.

Q: Do the housing material differences affect performance?

A: The 796417-2 uses Polyamide FR15 (Nylon FR15) housing; the 1776253-2 uses Polyamide PA66 (Nylon 6/6) housing. Both materials support the identical operating temperature range (-55°C ~ 105°C) and electrical specifications. Material selection does not impact electrical or mechanical compatibility within the specified application parameters.

Q: What is the contact plating difference?

A: The 796417-2 features brass contacts with copper-tin plating. The 1776253-2 features brass contacts with tin plating. Both plating systems provide equivalent electrical conductivity and corrosion resistance for the specified voltage (250 V) and current (7 A) ratings.

Q: Can I use the 1776253-2 in applications requiring RoHS compliance?

A: Yes. The 1776253-2 is ROHS3 compliant, making it suitable for applications subject to RoHS directives. The 796417-2 is RoHS non-compliant and should not be used in RoHS-regulated applications.
