TE Connectivity 1-926476-4 Rectangular Connector Housing – Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-926476-4 is a 28-position rectangular connector receptacle housing designed for 0.100" (2.54mm) pitch applications. This component is part of the AMPMODU Mod IV series and serves as the female socket housing in modular connector assemblies. The housing accommodates crimp-terminated contacts and operates across an industrial temperature range of -65°C to 105°C.

This part is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified for applications requiring alternative manufacturer sourcing, inventory availability, or specific series compatibility within equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 1-926476-4 are qualified based on strict equivalence of the following parameters:

Critical Matching Parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 28
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing: 0.100" (2.54mm)
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Color: Black
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts maintain identical electrical and mechanical interfaces, allowing direct substitution in applications where the connector housing footprint, contact arrangement, and termination method are the primary design constraints. Variations in insulation material composition and operating temperature ranges are secondary considerations that do not affect mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All three connector housing options maintain Active product status and carry appropriate RoHS compliance certifications, confirming ongoing manufacturer support and environmental regulatory adherence.

TE Connectivity 1-926476-4 (AMPMODU Mod IV): Primary selection for applications requiring the extended operating temperature range of -65°C to 105°C. Thermoplastic insulation material provides baseline performance across standard industrial environments.

Molex 0022552283 (SL 70450): Qualified substitute offering polyester glass-filled insulation with operating range of -40°C to 105°C. RoHS3 compliance and unlimited MSL rating ensure compatibility with standard assembly and storage protocols. REACH Unaffected status provides additional regulatory clarity for European supply chains.

Amphenol ICC 65043-023LF (Mini-PV™, Basics+): Qualified substitute featuring polyphenylene modified insulation with operating range of -40°C to 105°C. RoHS compliance and REACH Unaffected status support global distribution requirements. This option is suitable for applications where the lower temperature limit of -40°C meets design specifications.

Selection between substitute parts depends on application temperature requirements, preferred connector series compatibility, and supply chain sourcing priorities. All three options provide identical mechanical interchangeability and electrical interface characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022552283 be used as a direct replacement for the TE Connectivity 1-926476-4?

A: Yes. Both housings share identical connector type, contact type, position count, pitch, row configuration, mounting method, and termination type. The Molex part operates at -40°C minimum temperature versus -65°C for the TE part. If your application operates above -40°C, direct substitution is mechanically and electrically valid.

Q: What is the difference between the insulation materials used in these three housings?

A: The TE Connectivity part uses thermoplastic insulation. The Molex part uses polyester glass-filled material. The Amphenol ICC part uses polyphenylene modified material. These material differences do not affect mechanical interchangeability or electrical performance in standard applications. Material selection reflects manufacturer design choices for specific environmental and manufacturing requirements.

Q: Are all three parts RoHS compliant?

A: Yes. The TE Connectivity and Molex parts carry RoHS3 compliance. The Amphenol ICC part carries RoHS compliance. All three meet current environmental regulatory requirements for restricted substance elimination.

Q: Does the operating temperature range difference affect substitution decisions?

A: The TE Connectivity part operates from -65°C to 105°C. Both substitute parts operate from -40°C to 105°C. If your application requires operation below -40°C, the TE Connectivity part is required. For applications operating within -40°C to 105°C, all three parts are functionally equivalent.

Q: Are contacts included with these housings?

A: No. All three housings are supplied without contacts. Contacts must be sourced separately and crimped into the housing according to manufacturer specifications.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. These parts do not require special moisture control during storage, handling, or assembly. Standard warehouse storage conditions are appropriate.

Q: Can these 28-position housings be used with different pitch connectors?

A: No. These housings are specifically designed for 0.100" (2.54mm) pitch contact spacing. They are not compatible with connectors using different pitch specifications.

Q: What is the significance of the "Free Hanging (In-Line)" mounting type?

A: This designation indicates the housing is designed for direct board-to-board or cable-to-board connections without requiring a separate mounting bracket or backshell. The connector mounts directly to the PCB or cable assembly.
