GT8EC-8S-HU Equivalent & Substitute Parts

Part Overview

The GT8EC-8S-HU is an 8-position rectangular connector housing manufactured by Hirose Electric Co Ltd. This receptacle housing is designed for crimp contact termination with a 2.00mm pitch and operates across the temperature range of -40°C to 105°C. The part is currently in active production status with RoHS compliance and MSL Level 1 rating, indicating unlimited moisture sensitivity tolerance. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector pitch, position count, contact type, termination method, and operating temperature specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GT8EC-8S-HU are identified based on strict equivalence of the following critical parameters:

• Connector pitch: 0.079" (2.00mm) — determines mechanical and electrical compatibility
• Position count: 8 positions — defines contact array configuration
• Contact type: Female socket receptacle — ensures mating compatibility
• Termination method: Crimp — specifies contact attachment process
• Mounting configuration: Free hanging (in-line) — defines installation method
• Operating temperature range: -40°C to 105°C — establishes thermal performance envelope
• Fastening mechanism: Latch lock — ensures secure connection retention

The substitute part 0355070800 (Molex Sherlock 35507 series) meets all these criteria, making it a parametric equivalent for applications requiring an 8-position, 2.00mm pitch receptacle housing with crimp termination.

Parameter Comparison

Engineering Selection Recommendations

Both the GT8EC-8S-HU and 0355070800 are active production parts with current availability. The Hirose GT8EC-8S-HU carries RoHS compliance certification, while the Molex 0355070800 carries ROHS3 compliance, both meeting regulatory requirements for restricted substance elimination. Selection between these parts should be based on:

• Supply chain availability: The Molex part shows significantly higher inventory (246,493 pcs vs. 1,029 pcs)
• Existing connector ecosystem: If the application already uses Hirose GT8E series connectors, maintaining the same manufacturer may simplify procurement and assembly procedures
• Regulatory requirements: Both parts satisfy RoHS compliance; ROHS3 compliance of the Molex part indicates compliance with the most current restriction standards
• Insulation material differences: Hirose uses Polybutylene Terephthalate (PBT); Molex uses Polyester — both materials support the specified operating temperature range

Frequently Asked Questions (FAQ)

Q: Can the Molex 0355070800 directly replace the Hirose GT8EC-8S-HU in existing designs?

A: Yes, provided that the mating connector is compatible with both the 2.00mm pitch and the specific contact geometry of each manufacturer. The parametric specifications are equivalent; however, physical dimensions and contact interface details should be verified against the respective manufacturer datasheets.

Q: What is the significance of the pitch specification in connector substitution?

A: Pitch (0.079" or 2.00mm) defines the center-to-center spacing between contact positions. Substitutes must maintain identical pitch to ensure mechanical alignment and electrical continuity with mating connectors. A mismatch in pitch renders the parts incompatible.

Q: Are the insulation materials (PBT vs. Polyester) interchangeable?

A: Both materials support the operating temperature range of -40°C to 105°C. Material selection depends on specific application requirements such as chemical resistance, mechanical stress, or environmental exposure. Consult application-specific requirements before substitution.

Q: What does "Contacts Not Included" mean for these housings?

A: Both the GT8EC-8S-HU and 0355070800 are connector housings only. Crimp contacts must be sourced separately and must be compatible with the 2.00mm pitch and the specific contact cavity geometry of the selected housing manufacturer.

Q: How does MSL Level 1 affect component handling?

A: MSL Level 1 (Unlimited) indicates that these connector housings have unlimited shelf life and do not require moisture-controlled storage or baking procedures prior to assembly, simplifying inventory management and reducing production constraints.
