TE Connectivity 770442-3 Rectangular Connector Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 770442-3 is a 4-position rectangular connector receptacle housing with 0.145" (3.68mm) pitch spacing. This component is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing production and maintenance applications. The housing accommodates crimp-terminated contacts with a locking ramp fastening mechanism and operates across the industrial temperature range of -55°C to 105°C. Substitute parts must maintain electrical and mechanical compatibility while offering active product status and continued availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 770442-3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 4
• Pitch: 0.145" (3.68mm)
• Number of Rows: 2
• Row Spacing: 0.145" (3.68mm)
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Locking Ramp
• Insulation Material: Polyamide (PA), Nylon
• Operating Temperature Range: -55°C ~ 105°C
• RoHS Compliance: Required

The substitute parts 770442-1 and 770432-1 satisfy all mandatory parameters. Both are manufactured by TE Connectivity AMP Connectors and maintain identical electrical and mechanical specifications. The primary distinction between substitutes is color (Natural vs. Black) and product status (Active vs. Obsolete). Color variation does not affect functional compatibility in applications where housing color is not a design constraint.

Parameter Comparison

Engineering Selection Recommendations

770442-1 (Primary Substitute): The 770442-1 shares the identical base product number (770442) with the main part, indicating direct lineage within the product family. This part maintains active product status with 4065 units in stock. All electrical and mechanical parameters are equivalent to the 770442-3. The housing color is Natural rather than Black. This part is recommended for applications where color specification is not a critical design requirement.

770432-1 (Secondary Substitute): The 770432-1 is a parametric equivalent from the Commercial .062" Pin and Socket series. All functional specifications match the main part identically. This part maintains active product status with 12960 units in stock, providing superior long-term availability. The housing color is Natural. This part is suitable for applications where connector interchangeability is required and color is not a design constraint.

Both substitute parts carry RoHS compliance certification and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility with the original component. Selection between 770442-1 and 770432-1 should be based on inventory availability requirements and design color specifications.

Frequently Asked Questions (FAQ)

Q: Can the 770442-1 and 770432-1 be used interchangeably with the 770442-3?

A: Both substitute parts are electrically and mechanically equivalent to the 770442-3 across all critical parameters including pitch, position count, row configuration, termination method, and operating temperature range. Interchangeability is confirmed for applications where housing color is not a design specification.

Q: What is the difference between the 770442-1 and 770432-1 substitutes?

A: The primary difference is product series designation. The 770442-1 belongs to the same base product family (770442) as the main part, while the 770432-1 is from the Commercial .062" Pin and Socket series. Both maintain identical electrical and mechanical specifications. The 770432-1 offers higher inventory availability (12960 units vs. 4065 units).

Q: Why is the 770442-3 listed as obsolete?

A: The 770442-3 is classified as obsolete, indicating discontinued production. The active equivalents 770442-1 and 770432-1 provide continued access to functionally identical connector housings with ongoing manufacturer support and availability.

Q: Does the color difference between Black (770442-3) and Natural (substitutes) affect electrical performance?

A: Housing color is a cosmetic specification that does not affect electrical or mechanical performance. Color selection should be based on design requirements and application aesthetics only.

Q: Are the substitute parts RoHS compliant?

A: Both 770442-1 and 770432-1 are RoHS compliant, matching the compliance status of the original 770442-3 part.

Q: What is the moisture sensitivity level for these connector housings?

A: All three parts (770442-3, 770442-1, and 770432-1) carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Do these connector housings include contacts?

A: No. All three parts are housings only. Contacts must be sourced separately and crimped into the housing according to TE Connectivity specifications.
