GT8E-7P-DSA Equivalent & Substitute Parts

Part Overview

The GT8E-7P-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 7 positions with 0.079" (2.00mm) pitch, shrouded 4-wall construction, and solder termination with latch lock fastening. The part is classified as obsolete, making identification of active equivalent alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GT8E-7P-DSA is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (7)
• Mating pitch (0.079" / 2.00mm)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Latch Lock)
• Contact material and finish (Brass with Tin plating)

The GT8E-7P-DSA(55) variant meets all these criteria while offering active product status and enhanced specifications including defined operating temperature range (-40°C to 105°C), current rating (1A), and voltage rating (250VAC). The primary difference is packaging format (Tray vs. standard) and insulation material composition (Polyamide/Nylon vs. PBT), which do not affect functional compatibility in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

The GT8E-7P-DSA(55) is the direct active equivalent for the obsolete GT8E-7P-DSA. Selection of this substitute is based on:

• Identical mechanical and electrical interface specifications across all critical mating parameters
• Active product status ensuring continued availability and supply chain support
• Enhanced compliance certification (ROHS3 vs. RoHS Compliant) and REACH unaffected status
• Defined operating temperature range (-40°C to 105°C) and electrical ratings (1A at 250VAC) providing explicit performance boundaries
• Equivalent MSL rating and moisture sensitivity characteristics
• Identical ECCN and HTSUS classification for regulatory and trade purposes

The GT8E-7P-DSA(55) is suitable for direct replacement in all applications originally designed for the GT8E-7P-DSA without modification to PCB layout, mating connector specifications, or assembly procedures.

Frequently Asked Questions (FAQ)

Q: Can GT8E-7P-DSA(55) be used as a direct replacement for GT8E-7P-DSA?

A: Yes. Both parts share identical connector type, contact configuration, pitch, mounting method, shrouding, termination, and fastening specifications. The GT8E-7P-DSA(55) is the active equivalent variant.

Q: What is the difference between GT8E-7P-DSA and GT8E-7P-DSA(55)?

A: The primary differences are product status (Obsolete vs. Active), packaging format (standard vs. Tray), insulation material composition (PBT vs. Polyamide/Nylon), and the provision of explicit operating temperature (-40°C to 105°C) and electrical ratings (1A, 250VAC) in the substitute variant. Functional compatibility remains unchanged.

Q: Are there any compatibility concerns with the insulation material change from PBT to Polyamide/Nylon?

A: No. Both materials are suitable for the specified application parameters. The change does not affect mechanical fit, electrical performance, or thermal characteristics within the defined operating range.

Q: What packaging format is supplied with GT8E-7P-DSA(55)?

A: GT8E-7P-DSA(55) is supplied in Tray packaging, whereas the original GT8E-7P-DSA did not specify a packaging format. Verify packaging requirements for your procurement and assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. GT8E-7P-DSA is RoHS Compliant, and GT8E-7P-DSA(55) is ROHS3 Compliant. Both meet RoHS requirements. Additionally, GT8E-7P-DSA(55) is REACH Unaffected.

Q: What are the electrical specifications for GT8E-7P-DSA(55)?

A: Operating temperature range is -40°C to 105°C. Current rating is 1A. Voltage rating is 250VAC. The original GT8E-7P-DSA did not provide these specifications.
