Key Parameters

Substitute Part Grouping Explanation

Substitution of terminal block components is determined by strict equivalence across electrical performance parameters, mechanical interface dimensions, and wire termination compatibility. The primary substitute for 796462-3 is identified based on the following critical parameters:

Electrical Equivalence Criteria:

• Current rating: 10 A
• Voltage rating: 300 V
• Wire gauge acceptance: 14-22 AWG
• Operating temperature range: -55°C ~ 105°C

Mechanical Equivalence Criteria:

• Position count: 3 positions per level
• Pitch spacing: 0.197" (5.00mm)
• Mating orientation: Horizontal with Board
• Mounting configuration: Through Hole PCB mounting

Material and Contact Specifications:

• Contact material and plating: Brass - Nickel Tin Plated
• Clamp material: Steel, Stainless
• Housing material: Polyamide (PA)

The substitute part 1776261-3 maintains full electrical and mechanical compatibility with the original 796462-3 across all specified parameters. The primary distinction is the transition from obsolete to active product status and updated housing material formulation (PA FR15 to PA66), with corresponding RoHS compliance improvement.

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 1776261-3

The 1776261-3 is the direct active equivalent for the obsolete 796462-3. Selection of this substitute is based on the following engineering factors:

Product Status Alignment: The 796462-3 is classified as obsolete, creating supply chain risk for new production and long-term maintenance applications. The 1776261-3 maintains active product status with confirmed inventory availability, ensuring continued component sourcing.

Electrical and Mechanical Compatibility: All critical electrical parameters (10 A current, 300 V voltage, 14-22 AWG wire gauge, -55°C to 105°C operating range) and mechanical specifications (3 positions, 5.00mm pitch, horizontal board mounting, through-hole configuration) are identical between the main part and substitute.

Regulatory Compliance Enhancement: The 1776261-3 achieves RoHS compliance status, whereas the 796462-3 is RoHS non-compliant. This compliance improvement supports regulatory requirements in manufacturing environments subject to RoHS directives.

Material Specification Update: The housing material transition from PA FR15 to PA66 represents a material formulation update within the polyamide family. Both materials maintain equivalent mechanical and thermal performance within the specified operating temperature range.

Wire Termination Functional Equivalence: While the termination mechanism differs in nomenclature (Spring Cage Tension Clamp versus Leg Spring Push-In Spring), both configurations provide screwless wire termination for the 14-22 AWG wire gauge range, maintaining functional compatibility with existing wire preparation and installation procedures.

Frequently Asked Questions (FAQ)

Q: Can 1776261-3 be used as a direct replacement for 796462-3 in existing PCB designs?

A: Yes. The 1776261-3 maintains identical pitch spacing (5.00mm), position count (3), mounting type (through-hole), and mating orientation (horizontal with board). PCB footprints designed for 796462-3 are compatible with 1776261-3 without modification.

Q: What is the difference in wire termination between these two parts?

A: The 796462-3 uses a spring cage tension clamp termination mechanism, while the 1776261-3 uses a leg spring push-in spring mechanism. Both are screwless termination systems that accept 14-22 AWG wire. The functional outcome—secure wire retention and electrical contact—is equivalent.

Q: Are there electrical performance differences between the two parts?

A: No. Both parts have identical current rating (10 A), voltage rating (300 V), operating temperature range (-55°C to 105°C), and contact material specifications (Brass - Nickel Tin Plated).

Q: Why is the housing material different between 796462-3 and 1776261-3?

A: The 796462-3 uses PA FR15 (polyamide FR15), while 1776261-3 uses PA66 (polyamide 6/6). Both are polyamide-based materials with equivalent mechanical and thermal performance within the specified operating range. The material update reflects current manufacturing standards and supports improved RoHS compliance.

Q: Is the 1776261-3 available in the same packaging as 796462-3?

A: The 1776261-3 is supplied in bulk packaging, whereas the original 796462-3 packaging specification was not provided. Packaging format should be confirmed with the supplier based on production volume requirements.

Q: What is the inventory status for the substitute part?

A: The 1776261-3 has 818 pieces of new original stock currently available, providing adequate supply for production and maintenance applications.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition restrictions (lead, cadmium, mercury, etc.) and does not affect electrical performance, current capacity, voltage rating, or operating temperature range. The 1776261-3 RoHS compliance status is a regulatory and environmental advantage with no performance trade-offs.
