TE Connectivity AMP Connectors 770602-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 770602-3 is a 3-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 utilizes crimp contact termination with a locking ramp fastening mechanism. The part is classified as obsolete, necessitating identification of equivalent substitute components for ongoing procurement and design requirements. Substitute parts must maintain functional compatibility through matching electrical and mechanical parameters while accommodating available inventory from active product lines.

Substitute Part Grouping Explanation

Substitute parts for the 770602-3 are classified into two categories based on substitution compatibility:

Direct Substitute (Preferred): Part number 1375820-3 from TE Connectivity AMP Connectors maintains identical electrical and mechanical parameters with the main part. Both components share the same connector type (receptacle), contact type (female socket), number of positions (3), pitch (0.100"/2.54mm), number of rows (1), mounting type (free hanging in-line), contact termination (crimp), and fastening type (locking ramp). The 1375820-3 belongs to the CST-100 II series and carries active product status with RoHS compliance certification. The primary difference is housing color (white versus natural) and insulation material specification (polyamide with glass fill).

Similar Substitute (Cross-Manufacturer): Part number 0022011032 from Molex represents a cross-manufacturer alternative with notable parameter variations. While this component maintains receptacle connector type, 3-position configuration, single-row layout, free-hanging in-line mounting, and crimp termination, it operates at a different pitch specification (0.098"/2.50mm versus 0.100"/2.54mm). The contact type is non-gendered rather than female socket, and fastening mechanism differs (polarizing key feature without specified locking ramp). This substitute requires mechanical and electrical compatibility verification at the system level.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The 1375820-3 is the primary substitute for the obsolete 770602-3. Both components are manufactured by TE Connectivity AMP Connectors and maintain identical pitch, position count, mounting configuration, and termination method. The 1375820-3 carries active product status with confirmed RoHS compliance and specified operating temperature range (-55°C to 105°C), providing superior long-term availability and regulatory alignment. Housing color variation (white versus natural) does not affect electrical or mechanical function. This substitute is suitable for direct design migration without circuit modification.

For Cross-Manufacturer Substitution: The Molex 0022011032 presents a viable alternative when TE Connectivity components are unavailable. However, the pitch differential (0.098" versus 0.100") requires mechanical compatibility assessment with mating connectors and printed circuit board layouts. The non-gendered contact type and polarizing key fastening mechanism differ from the original locking ramp design. This substitute is applicable only when system-level compatibility has been established and documented. The component carries ROHS3 compliance and operates across -40°C to 105°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 1375820-3 directly replace the 770602-3 without design modification?

A: Yes. The 1375820-3 maintains identical electrical and mechanical parameters including pitch (0.100"/2.54mm), position count (3), connector type (receptacle), contact type (female socket), mounting configuration (free hanging in-line), and termination method (crimp with locking ramp). Housing color difference does not affect functional compatibility.

Q: What is the primary limitation of the Molex 0022011032 as a substitute?

A: The 0022011032 operates at 0.098" (2.50mm) pitch compared to the 0.100" (2.54mm) specification of the 770602-3. This pitch differential affects mechanical compatibility with mating connectors and PCB footprints. Additionally, the contact type is non-gendered and fastening mechanism uses a polarizing key rather than a locking ramp. System-level compatibility verification is required before implementation.

Q: Are there inventory considerations when selecting between substitute parts?

A: Yes. The 1375820-3 maintains 10,212 pieces in active inventory with bulk packaging, while the 0022011032 provides 24,535 pieces. The 770602-3 original part has 1,118 pieces remaining in stock but carries obsolete status. For ongoing procurement, the 1375820-3 offers superior long-term availability through its active product classification.

Q: Do the substitute parts meet current regulatory requirements?

A: The 1375820-3 carries RoHS Compliant certification with REACH status vendor undefined. The 0022011032 carries ROHS3 Compliant certification with REACH Unaffected status. Both components satisfy current regulatory frameworks for electronic component procurement. The original 770602-3 does not specify RoHS status.

Q: What is the significance of the operating temperature specifications?

A: The 1375820-3 operates across -55°C to 105°C, providing extended low-temperature performance compared to the 0022011032 range of -40°C to 105°C. For applications requiring operation below -40°C, the 1375820-3 is the appropriate selection. The original 770602-3 does not specify operating temperature limits.

Q: Are contacts included with these connector housings?

A: No. All three components (770602-3, 1375820-3, and 0022011032) are connector housings only. Contacts must be procured separately and are not included with the housing. Ensure contact specifications match the crimp termination requirements of the selected housing.
