Key Parameters

Substitute Part Grouping Explanation

Substitution of the GT8E-20DP-DS is determined by strict equivalence across the following critical parameters:

• Series and Connector Family: Both parts must belong to the GT8E series manufactured by Hirose Electric Co Ltd
• Electrical Configuration: Identical number of positions (20), rows (2), and mating pitch (0.079" / 2.00mm)
• Mechanical Interface: Matching row spacing (0.079" / 2.00mm), mounting type (through hole, right angle), and shrouding design (shrouded 4-wall)
• Contact Specifications: Same contact type (male pin), material (brass), finish (tin), and post length (0.118" / 3.00mm)
• Termination and Fastening: Solder termination with latch lock fastening
• Material and Environmental: PBT insulation, black color, MSL 1 rating

The GT8E-20DP-DS(55) qualifies as a direct substitute based on full alignment with all these parameters while offering active product status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The GT8E-20DP-DS(55) is the direct substitute for the obsolete GT8E-20DP-DS. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector configuration, contact geometry, pitch, mounting orientation, and termination method.

The GT8E-20DP-DS(55) offers the following advantages for new designs and ongoing procurement:

• Active Product Status: The substitute is currently in active production, ensuring long-term availability and supply chain continuity
• Enhanced Compliance: ROHS3 Compliant certification provides updated regulatory alignment compared to the RoHS Compliant status of the original part
• REACH Unaffected Status: Confirms compliance with European chemical regulations
• Specified Operating Parameters: The substitute includes defined operating temperature range (-40°C ~ 105°C), current rating (1A), and voltage rating (250VAC), providing explicit electrical performance boundaries
• Solder Retention Feature: Enhanced manufacturing feature improves assembly reliability during soldering operations

Both parts share identical MSL 1 (Unlimited) moisture sensitivity classification, ECCN EAR99 export control designation, and HTSUS commodity code 8536.69.4040.

Frequently Asked Questions (FAQ)

Q: Can GT8E-20DP-DS(55) be used as a direct replacement for GT8E-20DP-DS in existing designs?

A: Yes. The GT8E-20DP-DS(55) maintains full electrical and mechanical compatibility with the GT8E-20DP-DS. All critical parameters including position count, pitch, row spacing, mounting type, contact specifications, and termination method are identical. No design modifications are required.

Q: What is the primary reason for substitution?

A: The GT8E-20DP-DS is classified as obsolete. The GT8E-20DP-DS(55) is the active equivalent part from Hirose Electric Co Ltd, ensuring continued availability for procurement and new production builds.

Q: Are there any differences in packaging or handling?

A: Both parts are supplied in tray packaging with MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture control requirements during storage or handling.

Q: What are the electrical specifications of the substitute part?

A: The GT8E-20DP-DS(55) is rated for 1A current at 250VAC with an operating temperature range of -40°C to 105°C. These specifications apply to the connector header assembly.

Q: Does the substitute part meet current regulatory requirements?

A: Yes. The GT8E-20DP-DS(55) is ROHS3 Compliant and REACH Unaffected, meeting current European regulatory standards. Both parts share the same ECCN EAR99 export classification.

Q: Are there any feature differences between the two parts?

A: The original part includes a board guide feature, while the substitute includes solder retention. Solder retention is a manufacturing enhancement that improves assembly reliability during the soldering process and does not affect mechanical or electrical compatibility.

Q: What is the contact configuration of this connector?

A: The GT8E-20DP-DS(55) features 20 male pin contacts arranged in 2 rows with a 0.079" (2.00mm) mating pitch and 0.079" (2.00mm) row spacing. Contacts are brass with tin finish on both mating and post surfaces, with a post length of 0.118" (3.00mm).

Q: Is this connector suitable for board-to-cable applications?

A: Yes. Both the GT8E-20DP-DS and GT8E-20DP-DS(55) are designed for board-to-cable/wire style connections with through-hole, right-angle mounting and solder termination.
