Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2440-2 is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Current rating (5A), voltage rating (30VAC/60VDC), and termination type (threaded and turret with 8-32 thread).

Mechanical Specifications: Miniature dual configuration, knurled head style, cross hole diameter (0.086"/2.18mm), head size (0.380" OD/9.65mm), and panel thickness tolerance (0.188"/4.80mm).

Material and Construction: Brass body with gold plating, polycarbonate insulation, brass nut with nickel plating, and black/red color designation.

Compliance: ROHS3 compliance and REACH unaffected status.

The substitute part 2440-0 meets all these criteria and is classified as an equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The 2440-0 is the direct equivalent substitute for the obsolete 2440-2. Both parts share identical electrical ratings, mechanical dimensions, material specifications, and compliance certifications. The primary distinction is product status: the 2440-0 is currently active and available, while the 2440-2 is obsolete. For applications currently using the 2440-2, the 2440-0 provides full functional and physical compatibility without design modification. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across component transitions.

Frequently Asked Questions (FAQ)

Q: Can the 2440-0 directly replace the 2440-2 in existing designs?

A: Yes. The 2440-0 is electrically and mechanically identical to the 2440-2 across all specified parameters, including current rating, voltage rating, thread specification, dimensional tolerances, and material composition. No design changes are required.

Q: What is the difference between the 2440-2 and 2440-0?

A: The parts are functionally equivalent. The primary difference is product status: the 2440-2 is obsolete, while the 2440-0 is active and currently available for procurement.

Q: Are there packaging differences between these parts?

A: The 2440-2 packaging specification is not provided in the technical data. The 2440-0 is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 2440-2 and 2440-0 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component sourcing.

Q: What are the critical parameters for substitution in this connector category?

A: For miniature dual binding post connectors, substitution eligibility is determined by: termination thread specification (8-32), current and voltage ratings (5A/30VAC/60VDC), cross hole diameter (0.086"), head size (0.380" OD), panel thickness tolerance (0.188"), material composition (brass body with gold plating), insulation type (polycarbonate), and color designation (black/red).
