TE Connectivity 2-794550-2 Rectangular Connector Plug Housing – Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-794550-2 is a 22-position rectangular connector plug housing from the AMP-DUAC series. This component is a natural-colored, panel-mount connector housing designed for crimp contact termination with a 0.165" (4.20mm) pitch configuration. The part is classified as Active product status and is RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited).

Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when design flexibility permits selection from equivalent connector housings that maintain the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the 2-794550-2 are identified based on strict parametric equivalence across the following critical specifications:

Mandatory Matching Parameters:

• Connector Type: Plug
• Contact Type: Male Pin
• Number of Positions: 22
• Pitch: 0.165" (4.20mm)
• Number of Rows: 2
• Row Spacing: 0.165" (4.20mm)
• Mounting Type: Panel Mount, Snap-In
• Contact Termination: Crimp
• Fastening Type: Locking Ramp
• Color: Natural
• Insulation Material: Polyamide (PA), Nylon
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts 2-1969599-2 and 2-794953-2 satisfy all mandatory matching parameters. Both parts are manufactured by TE Connectivity AMP Connectors and maintain identical connector geometry, contact configuration, and termination methodology. Differences in series designation (VAL-U-LOK versus AMP-DUAC) and operating temperature ranges do not affect substitution eligibility within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

All three parts—2-794550-2, 2-1969599-2, and 2-794953-2—are Active product status and maintain full compliance with RoHS regulations. The main part (2-794550-2) and substitute 2-794953-2 are both RoHS Compliant, while substitute 2-1969599-2 carries ROHS3 Compliant status, indicating enhanced regulatory alignment.

The primary distinction between the main part and substitutes lies in operating temperature range. The 2-794550-2 supports -55°C to 105°C, while both substitutes (2-1969599-2 and 2-794953-2) support -40°C to 105°C. Applications requiring operation below -40°C must use the main part number 2-794550-2.

All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling. The insulation material specifications (Polyamide PA versus PA66) are both acceptable polyamide formulations for this connector class and do not affect functional interchangeability within the specified parameter set.

Frequently Asked Questions (FAQ)

Q: Can 2-1969599-2 or 2-794953-2 be used as direct replacements for 2-794550-2?

A: Both substitute parts are parametrically equivalent to 2-794550-2 across all critical connector specifications including position count, pitch, mounting configuration, and termination method. Direct substitution is permissible provided the application operating temperature does not fall below -40°C. If operation below -40°C is required, the main part 2-794550-2 must be used.

Q: What is the difference between the AMP-DUAC series (main part) and VAL-U-LOK series (substitutes)?

A: Series designation reflects product line classification within TE Connectivity's connector portfolio. Both series employ identical connector geometry, contact configuration, and mechanical specifications for this 22-position, 4.20mm pitch housing. Series differences do not affect electrical or mechanical compatibility.

Q: Are there any packaging differences between these parts?

A: The main part 2-794550-2 is supplied in standard packaging. Substitutes 2-1969599-2 and 2-794953-2 are supplied in Bulk packaging. Packaging format does not affect component functionality or interchangeability.

Q: Do these connector housings include contacts?

A: No. All three parts (2-794550-2, 2-1969599-2, and 2-794953-2) are connector housings only. Contacts are not included and must be sourced separately. Ensure selected contacts are compatible with crimp termination and the 22-position, 2-row configuration.

Q: What is the significance of Moisture Sensitivity Level 1?

A: Moisture Sensitivity Level 1 (Unlimited) indicates these connector housings have no moisture sensitivity constraints. No special storage, handling, or baking procedures are required prior to assembly or installation.

Q: Are all three parts RoHS compliant?

A: Yes. The main part 2-794550-2 and substitute 2-794953-2 are RoHS Compliant. Substitute 2-1969599-2 is ROHS3 Compliant, which represents an enhanced compliance standard. All three parts meet RoHS regulatory requirements.
