GT8E-2P-DSA Equivalent & Substitute Parts

Part Overview

The GT8E-2P-DSA is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting in board-to-cable/wire applications. This connector features a 2-position, single-row configuration with 0.079" (2.00mm) pitch and shrouded 4-wall design. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GT8E-2P-DSA is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and mating pitch (0.079" / 2.00mm)
• Number of positions (2) and row configuration (1 row)
• Mounting method (through hole) and termination type (solder)
• Shrouding design (shrouded 4-wall) and fastening mechanism (latch lock)
• Contact material (brass) and finish specifications (tin-plated)
• Physical dimensions: insulation height (0.476" / 12.10mm), contact post length (0.118" / 3.00mm)
• Compliance certifications (RoHS, MSL rating)

The substitute part GT8E-2P-DSA(55) maintains full electrical and mechanical compatibility with the original GT8E-2P-DSA while offering active product status and improved availability. The primary distinction is the packaging format (tray versus standard) and enhanced operational specifications provided by the active variant.

Parameter Comparison

Engineering Selection Recommendations

The GT8E-2P-DSA(55) is the direct active equivalent for the obsolete GT8E-2P-DSA. Both parts maintain identical electrical and mechanical specifications across all critical connector parameters, including pitch, position count, shrouding configuration, and contact geometry.

Selection of GT8E-2P-DSA(55) is supported by the following factors:

• Active product status ensures continued manufacturing support and supply chain availability
• ROHS3 compliance provides enhanced regulatory alignment compared to the RoHS Compliant designation of the original part
• Documented operating temperature range (-40°C ~ 105°C) and electrical ratings (1A at 250VAC) provide explicit performance boundaries
• Tray packaging format accommodates high-volume production workflows
• Significantly higher inventory availability (1973 units versus 975 units) reduces procurement lead time

For applications requiring the GT8E-2P-DSA, direct substitution with GT8E-2P-DSA(55) maintains full form, fit, and function compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Are GT8E-2P-DSA and GT8E-2P-DSA(55) electrically and mechanically interchangeable?

A: Yes. Both parts share identical specifications for connector type, contact configuration, mating pitch (2.00mm), shrouding design, mounting method, and contact materials. The parts are direct substitutes with no design changes required.

Q: What is the significance of the "(55)" designation in GT8E-2P-DSA(55)?

A: The "(55)" suffix indicates a packaging variant. GT8E-2P-DSA(55) is supplied in tray packaging, whereas the original GT8E-2P-DSA uses standard packaging. The electrical and mechanical specifications remain identical.

Q: Why is the original GT8E-2P-DSA classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. GT8E-2P-DSA(55) is the active production equivalent and is recommended for all new designs and procurement.

Q: What are the operating temperature and electrical limits for these connectors?

A: GT8E-2P-DSA(55) operates across -40°C to 105°C with a current rating of 1A and voltage rating of 250VAC. These specifications apply to the substitute part and define the operational envelope for circuit design.

Q: Does the insulation material differ between the two parts?

A: The main part specifies Polybutylene Terephthalate (PBT) insulation, while GT8E-2P-DSA(55) specifies Polyamide (PA) / Nylon. Both materials are suitable for the connector's intended application and maintain equivalent mechanical and electrical performance within the specified operating range.

Q: Are both parts RoHS compliant?

A: Yes. GT8E-2P-DSA carries RoHS Compliance certification, while GT8E-2P-DSA(55) carries ROHS3 Compliance certification. Both meet RoHS requirements; ROHS3 represents an updated compliance standard.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. Standard component storage practices apply.
