TE Connectivity AMP Connectors 770602-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 770602-2 is a 2-position rectangular connector receptacle housing with 0.100" (2.54mm) pitch, designed for free-hanging in-line mounting applications. This component belongs to the CST-100 series and features crimp contact termination with locking ramp fastening. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional and mechanical compatibility for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector housings is determined by strict equivalence across the following parameters: connector type (receptacle), contact type (female socket), number of positions (2), pitch (0.100"/2.54mm), number of rows (1), mounting type (free hanging in-line), contact termination method (crimp), and fastening mechanism (locking ramp). All identified substitute parts maintain these core electrical and mechanical parameters, ensuring functional interchangeability within applications designed for the 770602-2 housing.

The two substitute parts identified—TE Connectivity AMP Connectors 1375820-2 and Molex 0901560142—both satisfy these substitution criteria. The primary distinction between alternatives lies in product status (active versus obsolete), series designation, insulation material composition, color specification, and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity AMP Connectors 1375820-2 is the primary substitute for the obsolete 770602-2. This part maintains manufacturer continuity within the TE Connectivity AMP Connectors product line and represents an evolution within the CST series (CST-100 II). The 1375820-2 carries active product status with RoHS compliance certification, supporting modern regulatory requirements. Insulation material is specified as polyamide (PA) nylon with glass filling, and operating temperature range extends from -55°C to 105°C. This substitute is available in high inventory volume (1,000,100 pieces).

Molex 0901560142 serves as a parametric equivalent from an alternative manufacturer. This part satisfies all core substitution criteria and maintains active product status with ROHS3 compliance and REACH unaffected status. The insulation material is specified as polyphenylene oxide (PPO), with identical operating temperature range (-55°C to 105°C). Inventory availability is 8,042 pieces. Selection of this alternative introduces a cross-manufacturer substitution and should be evaluated based on application-specific requirements regarding insulation material properties and supplier qualification protocols.

Frequently Asked Questions (FAQ)

Q: Can the 1375820-2 directly replace the 770602-2 in existing applications?

A: Yes. The 1375820-2 maintains electrical and mechanical equivalence across all critical parameters: 2-position receptacle housing, 0.100" pitch, female socket contacts, crimp termination, locking ramp fastening, and free-hanging in-line mounting. The primary differences are product status (active versus obsolete), series designation (CST-100 II versus CST-100), and housing color (white versus natural).

Q: What is the significance of the color difference between substitute parts?

A: Color specification (natural, white, or black) is a cosmetic and identification parameter that does not affect electrical or mechanical function. Selection should be based on application requirements, assembly documentation, and visual identification protocols within the end-use system.

Q: Are there compatibility considerations between the TE Connectivity and Molex substitutes?

A: Both substitutes maintain identical electrical and mechanical parameters. The distinction lies in insulation material (polyamide nylon glass-filled versus polyphenylene oxide), manufacturer, series designation, and regulatory certifications. Selection between these alternatives should be based on supplier qualification, material compatibility with the application environment, and compliance requirements specific to the end-use industry.

Q: What does MSL 1 (Unlimited) indicate for these connector housings?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that these connector housings have no moisture sensitivity restrictions and do not require special handling, storage, or baking procedures prior to assembly or use.

Q: Are contacts included with these connector housings?

A: No. All three parts (770602-2, 1375820-2, and 0901560142) are connector housings only. Contacts must be sourced separately and are not included with the housing purchase.

Q: What is the difference between RoHS and ROHS3 compliance?

A: RoHS Compliant indicates compliance with the original Restriction of Hazardous Substances directive. ROHS3 Compliant indicates compliance with the updated RoHS 3 directive (2015/863/EU), which includes additional restricted substances. Both certifications indicate compliance with hazardous substance restrictions; ROHS3 represents the current regulatory standard.
