Part Overview

The TE Connectivity AMP Connectors 770602-7 is a 7-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 for ongoing production and maintenance applications. Substitute parts maintain identical electrical and mechanical specifications while offering improved availability and current product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector housings is determined by strict equivalence across core electrical and mechanical parameters. The following criteria establish valid substitution:

Primary Equivalence Criteria:

Connector type (Receptacle)
Contact type (Female Socket)
Number of positions (7)
Pitch specification (0.100" / 2.54mm)
Number of rows (1)
Mounting type (Free Hanging In-Line)
Contact termination method (Crimp)
Fastening type (Locking Ramp)
Moisture sensitivity level (MSL 1)

All identified substitute parts meet these core requirements. Secondary parameters including color, insulation material, operating temperature range, and series designation do not affect functional interchangeability for housing applications. Substitute parts are classified as either direct manufacturer equivalents (TE Connectivity) or parametric equivalents (alternative manufacturers).

Engineering Selection Recommendations

Direct Manufacturer Equivalent: TE Connectivity AMP Connectors 1375820-7

The 1375820-7 represents the primary substitute for the obsolete 770602-7. Both components are manufactured by TE Connectivity AMP Connectors and maintain identical electrical and mechanical specifications. The 1375820-7 is classified as active product status with significantly higher inventory availability (13,179 units). This part carries RoHS Compliant certification and operates across the extended temperature range of -55°C to 105°C. Selection of this part eliminates cross-manufacturer compatibility considerations and maintains supply chain consistency within the TE Connectivity product family.

Parametric Equivalents: Molex 0050579507 and 0901560147

Both Molex alternatives satisfy all core substitution criteria and are classified as active products. The 0050579507 (SL 70066 series) operates across -40°C to 105°C and utilizes polyester glass-filled insulation material. The 0901560147 (C-Grid III 90156 series) operates across -55°C to 105°C and utilizes polyphenylene oxide insulation material. Both Molex parts carry ROHS3 Compliant certification and REACH Unaffected status. Selection of Molex alternatives is appropriate when supply constraints or specific material requirements necessitate cross-manufacturer substitution.

Compliance Considerations

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity classification, matching the original specification. All parts carry EAR99 export classification. The TE Connectivity 1375820-7 and both Molex alternatives provide improved regulatory compliance through active RoHS certification status compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the 1375820-7 directly replace the 770602-7 in existing assemblies?

A: Yes. The 1375820-7 maintains identical electrical and mechanical specifications across all core parameters including connector type, contact type, position count, pitch, mounting type, termination method, and fastening type. The primary difference is product status (active versus obsolete) and color (white versus natural). Functional interchangeability is complete.

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

A: All three substitute parts meet identical core specifications. The TE Connectivity 1375820-7 offers the advantage of same-manufacturer sourcing. The Molex 0050579507 operates across a narrower temperature range (-40°C to 105°C versus -55°C to 105°C) and uses polyester insulation. The Molex 0901560147 matches the full temperature range and uses polyphenylene oxide insulation. Selection depends on supply availability, temperature requirements, and material compatibility needs.

Q: Are contacts included with these connector housings?

A: No. All parts in this comparison are connector housings only. Contacts are not included and must be sourced separately. Ensure that replacement contacts are compatible with the 0.100" (2.54mm) pitch specification and crimp termination method.

Q: What is the significance of the MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture sensitivity concerns. This classification applies to all parts in this comparison and means no special storage or handling requirements are necessary prior to assembly.

Q: Can I mix substitute parts within a single assembly?

A: Yes. All substitute parts maintain identical mechanical and electrical specifications for the housing function. However, consistent sourcing from a single manufacturer is recommended for supply chain management and documentation purposes.

Q: What is the difference between REACH Unaffected and Vendor Undefined status?

A: REACH Unaffected indicates the manufacturer has confirmed the part does not contain substances of very high concern (SVHC) listed under REACH regulations. Vendor Undefined indicates the manufacturer has not provided explicit REACH compliance documentation. For applications requiring confirmed REACH compliance, the TE Connectivity 1375820-7 or Molex alternatives with REACH Unaffected status are preferred.

Q: Are all substitute parts RoHS compliant?

A: The TE Connectivity 1375820-7 carries RoHS Compliant certification. Both Molex parts carry ROHS3 Compliant certification. The original 770602-7 does not specify RoHS status. For applications requiring RoHS compliance, all three substitute options are acceptable.
