Engineering Selection Recommendations

Primary Substitute: TE Connectivity 1776263-2

The 1776263-2 is the direct TE Connectivity equivalent within the Buchanan series. It maintains identical electrical ratings (10 A, 300 V), pitch (5.00mm), and mechanical configuration. The primary difference is the termination mechanism (leaf spring with wire guard versus rising cage clamp). This part is active, ROHS3 compliant, and REACH affected. Wire gauge accommodation is 16-24 AWG, which overlaps the main part's 14-22 AWG range. Screw torque specification is slightly lower (0.34 Nm versus 0.39 Nm). This substitute is suitable for applications where TE Connectivity sourcing is required and wire gauges do not exceed 24 AWG.

Secondary Substitutes: On Shore Technology ED130/2DS and ED130/2DSDG

Both ED130 series parts provide full compatibility with the 1776280-2 across all critical parameters: 2 positions, 5.00mm pitch, 90° wire entry, 10 A current rating, and 300 V voltage rating. These parts accommodate 14-22 AWG wire gauges, matching the main part specification. Contact material differs (copper beryllium versus brass), and insulation height is marginally lower (0.425" versus 0.433"). Both are active, ROHS3 compliant, and REACH unaffected. The ED130/2DSDG offers gray housing, while ED130/2DS provides blue housing. Screw torque is 0.4 Nm, slightly higher than the main part.

Tertiary Substitutes: On Shore Technology OSTTT020180 and OSTTT020181

The OSTTT series parts meet core position, pitch, and mounting requirements with 300 V voltage rating and screw termination. Wire gauge range is 16-22 AWG, which overlaps the main part's specification. Operating temperature range extends to 115°C, exceeding the main part's unspecified range. Contact material is phosphor bronze. Screw torque is significantly lower (0.2 Nm). These parts are active, ROHS3 compliant, and REACH unaffected. Plug wire entry orientation is not specified for these parts. Selection of OSTTT series should be limited to applications where the lower torque specification and unspecified wire entry orientation do not present compatibility concerns.

Compliance Considerations

All substitute parts are ROHS3 compliant and carry active product status, addressing the obsolescence of the main part. The 1776263-2 carries REACH affected status, while ED130 and OSTTT series parts are REACH unaffected. Selection should account for supply chain compliance requirements specific to the application region.

Frequently Asked Questions (FAQ)

Q: Can the 1776263-2 directly replace the 1776280-2 in existing designs?

A: The 1776263-2 maintains identical electrical ratings, pitch, position count, and mounting configuration. The termination mechanism differs (leaf spring with wire guard versus rising cage clamp), but both are screw-based systems. Direct mechanical and electrical compatibility is established. Wire gauge accommodation differs slightly (16-24 AWG versus 14-22 AWG), so applications using 14-15 AWG conductors require verification that the 1776263-2 can properly seat these larger gauges.

Q: What is the primary difference between the ED130/2DS and ED130/2DSDG?

A: Both parts are electrically and mechanically identical. The ED130/2DS features blue housing, while the ED130/2DSDG features gray housing. Selection between these variants is based on color coding requirements or visual identification standards in the application.

Q: Are the OSTTT020180 and OSTTT020181 interchangeable?

A: Both OSTTT parts share identical electrical specifications, wire gauge range, operating temperature, and screw torque. The part numbers differ, but no technical distinctions are provided in the available data. Interchangeability is established based on provided parameters.

Q: What wire gauge limitations apply when substituting with the 1776263-2?

A: The 1776263-2 accommodates 16-24 AWG wire gauges, while the 1776280-2 accommodates 14-22 AWG. Applications using 14-15 AWG conductors cannot use the 1776263-2 without verification that the termination mechanism properly seats these larger gauges. Applications using 23-24 AWG conductors cannot use the 1776280-2.

Q: How do screw torque specifications affect part selection?

A: Screw torque specifications define the maximum tightening force for terminal connections. The 1776280-2 specifies 0.39 Nm, while substitutes range from 0.2 Nm (OSTTT series) to 0.4 Nm (ED130 series). Installation procedures must follow the torque specification of the selected part to ensure proper conductor seating and electrical performance. Lower torque values (OSTTT series) may indicate different mechanical design and should be applied according to manufacturer guidance.

Q: What is the significance of the insulation height difference between parts?

A: Insulation height affects the physical envelope and mating depth with unshrouded header receptacles. The 1776280-2 specifies 0.433" (11.00mm), while ED130 series parts specify 0.425" (10.80mm). This 0.008" difference is minor but should be verified for applications with tight mechanical tolerances or custom header designs.

Q: Are all substitute parts suitable for the same operating temperature range?

A: The 1776280-2 does not specify an operating temperature range. Substitute parts specify ranges from -30°C to 105°C (ED130 series) and -40°C to 115°C (OSTTT series). Applications requiring operation outside these ranges should be evaluated against the main part's unspecified capability or the substitute part's documented limits.

Q: What compliance certifications should be considered for new designs?

A: All substitute parts are ROHS3 compliant and carry active product status. The 1776263-2 is REACH affected, while ED130 and OSTTT series parts are REACH unaffected. New designs should select parts based on regional compliance requirements and supply chain restrictions applicable to the target market.

Q: Can the ED130 series parts be used in applications originally designed for the 1776280-2?

A: The ED130/2DS and ED130/2DSDG provide full electrical and mechanical compatibility with the 1776280-2 across all critical parameters: 2 positions, 5.00mm pitch, 90° wire entry, 10 A current rating, 300 V voltage rating, and 14-22 AWG wire gauge accommodation. Contact material differs (copper beryllium versus brass), which may affect corrosion resistance in specific environments. Verification of contact material compatibility with the application environment is recommended.

Q: What is the inventory status of substitute parts?

A: The 1776280-2 is obsolete with 731 pieces in stock. Active substitutes have higher inventory availability: 1776263-2 (8025 pieces), ED130/2DS (5075 pieces), ED130/2DSDG (1063 pieces), OSTTT020180 (702 pieces), and OSTTT020181 (1114 pieces). Inventory levels support both immediate replacement needs and long-term supply planning.
