Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 794448-1 are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria include:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (6)
• Number of rows (2)
• Pitch - mating (0.165" / 4.20mm)
• Row spacing - mating (0.165" / 4.20mm)
• Mounting type (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Locking Ramp)
• Contact shape (Square)
• Material flammability rating (UL94 V-2)
• Moisture sensitivity level (MSL 1)

The Molex 0353180620 connector satisfies all critical matching parameters and serves as a direct functional equivalent for the obsolete TE Connectivity 794448-1.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0353180620 connector is the identified substitute for the obsolete TE Connectivity 794448-1. Selection of this substitute is based on the following engineering factors:

Product Status Consideration: The TE Connectivity 794448-1 is classified as obsolete, making the Molex 0353180620 an active product alternative with equivalent electrical and mechanical specifications.

Compliance and Certification: The Molex 0353180620 holds ROHS3 compliance status, whereas the original TE Connectivity part is RoHS non-compliant. For applications requiring RoHS compliance, the Molex substitute provides regulatory alignment. Both connectors maintain UL94 V-2 flammability ratings and identical MSL classifications.

Electrical and Mechanical Equivalence: The substitute part maintains identical pitch spacing (0.165" / 4.20mm), position count (6), row configuration (2), mounting orientation (through-hole right-angle), shrouding design (4-wall), and fastening mechanism (locking ramp). Contact geometry, termination method, and insulation material specifications are functionally equivalent.

Environmental Performance: Both connectors operate across the -55°C to 105°C temperature range and maintain unlimited moisture sensitivity classification (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can the Molex 0353180620 directly replace the TE Connectivity 794448-1 in existing designs?

A: The Molex 0353180620 provides functional equivalence based on matching connector type, position count, pitch spacing, mounting configuration, and shrouding design. Physical board layout compatibility depends on identical PCB footprint dimensions and mounting hole spacing. Verification of mechanical fit within the specific application enclosure is required.

Q: What are the key differences between these two connectors?

A: The primary differences are manufacturer identity, series designation, and compliance status. The Molex part is ROHS3 compliant while the TE Connectivity part is RoHS non-compliant. Contact finish specifications differ slightly (Tin versus Tin-Lead), and contact base materials differ (Brass versus Copper Alloy). Insulation material specifications vary between PA and PA66 formulations. The Molex connector is actively manufactured, whereas the TE Connectivity part is obsolete.

Q: Are the contact finishes compatible between these two connector types?

A: Both connectors utilize tin-based contact finishes suitable for solder termination. The TE Connectivity part specifies Tin-Lead finish with 150.0µin (3.81µm) thickness, while the Molex part specifies Tin finish. Both finishes are compatible with standard PCB solder processes and provide equivalent electrical conductivity for this application class.

Q: What is the significance of the different insulation materials?

A: The TE Connectivity 794448-1 uses Polyamide (PA) Nylon, while the Molex 0353180620 uses Polyamide (PA66) Nylon 6/6. Both materials provide equivalent mechanical strength, thermal stability across the -55°C to 105°C operating range, and UL94 V-2 flammability performance. PA66 formulation offers enhanced dimensional stability and chemical resistance in industrial environments.

Q: Does the contact material difference affect electrical performance?

A: Both Copper Alloy and Brass contact materials provide equivalent electrical conductivity and current-carrying capacity for this connector class. The material difference does not impact electrical performance for standard signal and power distribution applications within the specified voltage rating (600VAC).

Q: What packaging considerations apply to the Molex substitute?

A: The Molex 0353180620 is supplied in bulk packaging, whereas the TE Connectivity 794448-1 packaging specification is not provided. Bulk packaging typically indicates standard reel or tray configurations suitable for automated assembly processes. Confirm packaging format compatibility with procurement and assembly requirements.

Q: Are there any environmental or regulatory compliance advantages to using the Molex substitute?

A: The Molex 0353180620 holds ROHS3 compliance certification, making it suitable for applications subject to RoHS directives. The part is classified as REACH Unaffected, providing regulatory clarity for European market applications. The TE Connectivity original part carries undefined REACH status and RoHS non-compliance, potentially limiting use in regulated markets.
