TE Connectivity AMP Connectors 2005249-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2005249-4 is a rectangular connector housing designed for receptacle applications in the Power Double Lock series. This 2-position connector operates at a 0.156" (3.96mm) pitch and features panel mount, snap-in installation with crimp contact termination. The housing is constructed from polyamide (PA66) nylon 6/6 material and is rated for operating temperatures between -30°C and 105°C. This part is actively produced and RoHS compliant. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific application requirements necessitate alternative configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2005249-4 are identified based on strict parametric equivalence within the Power Double Lock series. The substitution logic is based on the following critical parameters that must remain constant:

• Connector type (Receptacle)
• Number of positions (2)
• Pitch specification (0.156" / 3.96mm)
• Contact type (Tab)
• Mounting configuration (Panel Mount, Snap-In)
• Contact termination method (Crimp)
• Insulation material (Polyamide PA66, Nylon 6/6)
• Fastening mechanism (Locking Ramp)
• Series designation (Power Double Lock)

The substitute part 2005249-1 maintains all critical electrical and mechanical parameters required for functional interchangeability. Variations in color, operating temperature range, and moisture sensitivity level do not affect the core connector functionality within their respective rated specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 2005249-4 and 2005249-1 are active products manufactured by TE Connectivity AMP Connectors and maintain full RoHS compliance. Selection between these parts should be based on application-specific requirements:

2005249-4 (Yellow Housing): Select this part when applications require operation across the extended temperature range of -30°C to 105°C. The yellow housing provides visual identification in field installations.

2005249-1 (Natural Housing): Select this part for applications operating within the -30°C to 65°C temperature range. The natural color housing is suitable for standard industrial applications where color coding is not a requirement. This part maintains higher inventory availability.

Both parts are manufactured from identical insulation material (Polyamide PA66, Nylon 6/6) and share all critical mechanical and electrical specifications. The choice between these substitutes depends solely on the thermal operating requirements of the target application and any color-coding requirements for system integration.

Frequently Asked Questions (FAQ)

Q: Can 2005249-1 be used as a direct replacement for 2005249-4?

A: The 2005249-1 is a direct functional substitute for 2005249-4 when the application operates within the -30°C to 65°C temperature range. Both parts share identical connector type, position count, pitch, contact configuration, mounting method, and termination specifications. The primary difference is the operating temperature upper limit and housing color.

Q: What is the significance of the color difference between these parts?

A: The color difference (yellow versus natural) is a visual identification feature only and does not affect electrical or mechanical performance. Color selection should be based on system integration requirements or field identification protocols.

Q: Are the contacts included with these connector housings?

A: No. Both 2005249-4 and 2005249-1 are connector housings only. Contacts must be sourced separately and are not included with these parts.

Q: What is the difference in operating temperature ranges?

A: The 2005249-4 operates from -30°C to 105°C, while the 2005249-1 operates from -30°C to 65°C. Applications requiring sustained operation above 65°C must use the 2005249-4. Applications within the lower temperature range can use either part.

Q: Are both parts RoHS compliant?

A: Yes. Both 2005249-4 and 2005249-1 are RoHS compliant and suitable for applications requiring environmental compliance certification.

Q: What is the pitch specification and why is it important?

A: Both parts operate at a 0.156" (3.96mm) pitch. This specification defines the center-to-center distance between contact positions and must match the mating connector and PCB layout. Pitch is a critical parameter for mechanical and electrical compatibility.

Q: Can these connectors be used in applications requiring high-temperature operation?

A: The 2005249-4 supports continuous operation up to 105°C and is suitable for high-temperature applications within this range. The 2005249-1 is limited to 65°C maximum and is not suitable for high-temperature applications.
