TE Connectivity AMP Connectors 770524-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 770524-1 is a 2-position rectangular connector housing designed for receptacle applications with a 0.625" (15.88mm) pitch. This component is classified as Obsolete, indicating that direct procurement from current manufacturing may be limited. The housing is configured as a free-hanging, in-line receptacle with female socket contacts and employs a locking ramp fastening mechanism. Due to its obsolete status, identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for ongoing production and service requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 770524-1 is based on the following critical parameters that must align between the main part and substitute candidates:

Primary Substitution Criteria:

• Number of Positions: 2
• Connector Type: Receptacle
• Contact Type: Socket
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Color: Black
• Row Configuration: 1 row
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 1969726-1 meets the core functional requirements for position count, connector orientation, contact type, mounting configuration, and termination method. Both parts are manufactured by TE Connectivity AMP Connectors and share identical RoHS and MSL classifications. The primary distinction lies in the fastening mechanism (friction lock versus locking ramp) and the availability of pitch specification data for the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The 1969726-1 serves as an active substitute for the obsolete 770524-1 based on the following engineering considerations:

Compliance and Regulatory Status: Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring compatibility with current environmental and regulatory requirements. The 1969726-1 carries Active product status, providing assured long-term availability and manufacturing support compared to the Obsolete status of the 770524-1.

Functional Compatibility: The substitute part preserves the critical functional parameters: 2-position configuration, receptacle orientation, socket contact type, free-hanging in-line mounting, and crimp termination. These parameters ensure mechanical and electrical compatibility within existing connector systems.

Design Considerations: The fastening mechanism differs between the two parts (friction lock versus locking ramp). This distinction requires evaluation within the specific application context to confirm that the friction lock mechanism provides equivalent retention and performance characteristics for the intended use case. The substitute part specifies Liquid Crystal Polymer (LCP) insulation material and an operating temperature range of -40°C to 200°C, providing additional environmental performance data not documented for the original part.

Frequently Asked Questions (FAQ)

Q: Can the 1969726-1 directly replace the 770524-1 in existing assemblies?

A: The 1969726-1 shares the same position count, connector type, contact configuration, mounting style, and termination method as the 770524-1. However, the fastening mechanism differs (friction lock versus locking ramp). Compatibility depends on whether the application can accommodate the friction lock mechanism without compromising retention or performance requirements.

Q: What is the significance of the pitch specification for the 770524-1?

A: The 770524-1 specifies a 0.625" (15.88mm) pitch, which defines the center-to-center spacing between contact positions. This parameter is critical for mechanical fit and electrical performance. The pitch specification for the 1969726-1 is not provided in available documentation; verification of pitch compatibility is necessary before substitution.

Q: Are both parts compliant with current environmental standards?

A: Yes. Both the 770524-1 and 1969726-1 are ROHS3 compliant and carry MSL rating 1 (Unlimited), indicating compatibility with current manufacturing and environmental regulations.

Q: What is the primary advantage of selecting the 1969726-1 over the 770524-1?

A: The 1969726-1 carries Active product status, ensuring current manufacturing availability and long-term supply chain support. The 770524-1 is classified as Obsolete, which may result in limited inventory and discontinued production.

Q: Does the operating temperature range of the 1969726-1 affect substitution suitability?

A: The 1969726-1 specifies an operating temperature range of -40°C to 200°C. If the original application operates within this range, the substitute part is suitable. If the original application requires operation outside this range, the temperature specification must be confirmed for the 770524-1 before proceeding with substitution.

Q: Are contacts included with either housing part?

A: No. Both the 770524-1 and 1969726-1 are connector housings supplied without contacts. Contacts must be procured separately and are not included with these components.
