Equivalent & Substitute Parts for TE Connectivity 1-770602-1

Part Overview

The TE Connectivity 1-770602-1 is an 11-position rectangular connector receptacle housing with 0.100" (2.54mm) pitch, designed for free-hanging in-line applications. This component features a natural color finish and employs 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 maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility for the 1-770602-1 is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (11), 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 specifications, ensuring mechanical and electrical interchangeability within the connector interface.

The substitute parts are grouped into two categories: direct manufacturer equivalents from TE Connectivity and parametric equivalents from alternative manufacturers. Both categories satisfy the dimensional and functional requirements for direct replacement in applications originally specified for the 1-770602-1.

Parameter Comparison

Engineering Selection Recommendations

1-1375820-1 (TE Connectivity AMP Connectors): This part represents the direct manufacturer equivalent within the CST-100 II series. The component maintains active product status and carries RoHS Compliance certification. Operating temperature range extends from -55°C to 105°C. This substitute is suitable for applications requiring continued support from the original equipment manufacturer and where RoHS compliance is mandated.

0050579511 (Molex): This parametric equivalent from Molex satisfies all core mechanical and electrical specifications. The part maintains active product status with ROHS3 Compliance certification. Operating temperature range is -40°C to 105°C. This substitute is appropriate for applications where cross-manufacturer sourcing is acceptable and where the specified operating temperature range is sufficient.

Both substitutes provide equivalent functional performance and mechanical compatibility. Selection between them depends on supply chain preferences, compliance requirements, and operating temperature specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can the 1-1375820-1 be used as a direct replacement for the 1-770602-1?

A: Yes. Both parts share identical specifications for connector type, contact type, number of positions, pitch, mounting type, contact termination, and fastening mechanism. The primary difference is product status (active versus obsolete) and color (white versus natural). Functional and mechanical interchangeability is confirmed.

Q: What are the differences between the TE Connectivity and Molex substitutes?

A: The TE Connectivity 1-1375820-1 and Molex 0050579511 differ in insulation material composition, operating temperature range, and compliance certifications. The TE part specifies polyamide (PA) nylon glass-filled insulation with -55°C to 105°C operating range and RoHS Compliance. The Molex part specifies polyester glass-filled insulation with -40°C to 105°C operating range and ROHS3 Compliance. Both maintain identical connector specifications and mechanical compatibility.

Q: Does color difference affect substitution compatibility?

A: Color is a cosmetic parameter that does not affect electrical or mechanical function. The natural, white, and black color options are interchangeable from a functional standpoint. Color selection should be based on application-specific requirements or assembly documentation.

Q: Are contacts included with these connector housings?

A: No. All three parts (1-770602-1, 1-1375820-1, and 0050579511) are connector housings only. Contacts must be sourced separately and are not included with the housing purchase.

Q: What is the significance of the Moisture Sensitivity Level (MSL) rating?

A: All three parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture control requirements. This specification is identical across all substitutes and does not present a constraint for substitution decisions.

Q: Can the Molex 0050579511 be used in applications requiring -55°C operation?

A: No. The Molex part specifies a minimum operating temperature of -40°C, which does not meet applications requiring -55°C operation. The TE Connectivity 1-1375820-1 supports the full -55°C to 105°C range and is the appropriate choice for such applications.
