Engineering Selection Recommendations

The Molex 0353180820 serves as the primary substitute for the obsolete TE Connectivity 794509-1. Selection of this substitute is supported by the following factors:

Product Status: The Molex 0353180820 is classified as an active product with current manufacturing availability, ensuring long-term supply chain continuity and design support.

Regulatory Compliance: The Molex substitute is RoHS3 compliant, whereas the original TE Connectivity part is RoHS non-compliant. This compliance status is significant for applications subject to RoHS directives and environmental regulations.

REACH Status: The Molex part is designated as REACH Unaffected, providing clarity on chemical substance compliance, compared to the TE Connectivity part with vendor-undefined REACH status.

Electrical and Mechanical Compatibility: Both connectors share identical pitch specifications (0.165" / 4.20mm), row configuration (2 rows), position count (8), mounting orientation (through-hole right-angle), shrouding design (4-wall), and fastening mechanism (locking ramp). These parameters ensure mechanical and electrical interchangeability in board-level applications.

Material and Environmental Specifications: Both parts maintain UL94 V-2 flammability ratings, MSL 1 moisture sensitivity levels, and equivalent insulation material classifications (polyamide/nylon variants), supporting equivalent performance in thermal and environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0353180820 be used as a direct replacement for the TE Connectivity 794509-1?

A: Yes. The Molex 0353180820 meets all critical electrical and mechanical parameters required for substitution, including connector type, contact configuration, pitch spacing, mounting orientation, shrouding design, and fastening mechanism. Both parts are classified as 8-position, 2-row headers with 0.165" (4.20mm) pitch and right-angle through-hole mounting.

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

A: The primary differences are product status and regulatory compliance. The TE Connectivity 794509-1 is obsolete and RoHS non-compliant, while the Molex 0353180820 is an active product with RoHS3 compliance. The Molex part also specifies REACH Unaffected status. Minor material variations exist in the polyamide formulation (PA versus PA66), but both meet UL94 V-2 flammability requirements.

Q: Are there any dimensional differences that could affect PCB layout?

A: The mating pitch (0.165" / 4.20mm) and row spacing (0.165" / 4.20mm) are identical between both parts. The Molex part specifies an insulation height of 0.378" (9.60mm) compared to 0.394" (10.00mm) for the TE Connectivity part. This 0.016" (0.40mm) difference should be evaluated against specific PCB clearance requirements and mechanical constraints in the application.

Q: What is the contact material composition for each connector?

A: The TE Connectivity 794509-1 uses copper alloy contacts with tin-lead finish. The Molex 0353180820 uses brass contacts with tin finish. Both materials provide equivalent electrical conductivity and corrosion resistance for standard board-level applications.

Q: Are both connectors suitable for the same operating temperature range?

A: The TE Connectivity 794509-1 specifies an operating temperature range of -55°C to 105°C. The Molex 0353180820 does not specify an operating temperature range in the provided data. Applications requiring confirmed temperature specifications should reference the Molex technical documentation.

Q: What is the significance of the RoHS compliance difference?

A: The Molex 0353180820 is RoHS3 compliant, meaning it meets current Restriction of Hazardous Substances directives. The TE Connectivity 794509-1 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the Molex substitute is the appropriate selection.

Q: Can these connectors be used interchangeably with mating connectors from different manufacturers?

A: Interchangeability depends on the mating connector specifications. Both the TE Connectivity and Molex headers share identical pitch (0.165" / 4.20mm), row spacing (0.165" / 4.20mm), and position configuration (8 positions, 2 rows). Mating connectors designed for these specifications are compatible with both headers.

Q: What is the inventory status for each part?

A: The TE Connectivity 794509-1 has 854 pieces in stock as new original inventory. The Molex 0353180820 has 6,626 pieces in stock as new original inventory. The Molex part offers significantly higher availability.
