TE Connectivity AMP Connectors 281282-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 281282-2 is a rectangular connector header designed for through-hole, right-angle mounting applications. This shrouded 20-position connector operates at 0.100" (2.54mm) pitch and features male pin contacts with gold-plated mating surfaces and tin-plated posts. The connector is classified as Active product status and is RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent rectangular connectors share the same critical electrical and mechanical parameters: 20-position configuration, 2-row layout, 0.100" (2.54mm) pitch, through-hole right-angle mounting, shrouded 4-wall design, solder termination, and male pin contact type. Alternative sources provide design flexibility, supply chain redundancy, and inventory availability across multiple manufacturers.

Frequently Asked Questions (FAQ)

Q: What defines substitution compatibility for the TE Connectivity 281282-2?

A: Substitution compatibility is established through matching of 20-position configuration, 2-row layout, 0.100" (2.54mm) pitch, through-hole right-angle mounting, shrouded 4-wall design, solder termination, male pin contacts, square contact shape, gold mating finish, tin post finish, and PBT glass-filled insulation. All listed parts meet these criteria.

Q: Are there differences in contact material between the main part and substitutes?

A: Yes. The main part uses Brass contacts. Substitute parts employ Brass, Phosphor Bronze, or Copper Alloy contact materials. These material variations do not affect mechanical or electrical compatibility within the specified parameter set.

Q: How do operating temperature ranges vary among substitutes?

A: Operating temperature ranges span from -55°C to 85°C (Hirose) to -55°C to 125°C (HARTING, Samtec HTST and TST-110-04-L models). The main part does not specify an operating temperature range. Selection should align with application thermal requirements.

Q: What packaging options are available?

A: Substitute parts are supplied in Tray, Bulk, or Tube packaging formats. Tray packaging is standard for Molex, HARTING, 3M D2520, and Hirose. Bulk packaging is used for 3M 30320 and 3M N2520. Samtec parts are supplied in Tube format.

Q: Does the Latch Holder fastening type on HARTING 09185206323 affect compatibility?

A: The HARTING part uses Latch Holder fastening instead of Push-Pull. This represents a functional difference in mating mechanism. Mechanical compatibility with mating receptacles designed for Push-Pull fastening is not established.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts carry either RoHS Compliant or ROHS3 Compliant status. The main part is RoHS Compliant. ROHS3 represents an updated compliance designation and does not preclude substitution.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life without moisture bake-out requirements. All listed parts, including the main part and all substitutes, carry this rating.

Q: Do contact finish thickness variations affect electrical performance?

A: Contact finish thickness variations are provided in the specification data but do not alter fundamental electrical compatibility. All parts maintain gold mating surfaces and tin post finishes as specified.

Q: Which substitute offers the highest current rating?

A: Samtec HTST-110-04-S-D-RA and both Samtec TST models specify 3.4A per contact current rating, the highest among all listed parts. The main part does not specify a current rating.

Q: Can TST-110-05-T-D-RA be used as a direct replacement despite tin mating finish?

A: TST-110-05-T-D-RA features tin mating contact finish rather than gold. This represents a material specification difference. Compatibility with receptacles designed for gold mating surfaces is not established.
