Engineering Selection Recommendations

Primary Substitute: Molex 0353181220

The Molex 0353181220 is the qualified substitute for the obsolete TE Connectivity 794511-1. Selection of this substitute is based on the following engineering criteria:

Functional Compatibility: All critical mating interface parameters are identical, including connector type, contact type, position count, row configuration, pitch, and row spacing. The mechanical mounting configuration, shrouding design, termination method, and fastening mechanism are equivalent.

Product Status and Availability: The TE Connectivity 794511-1 is classified as obsolete, creating supply chain constraints. The Molex 0353181220 maintains active product status with 12,399 pieces in stock, ensuring procurement availability for new designs and production requirements.

Regulatory Compliance: The Molex 0353181220 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The TE Connectivity 794511-1 is RoHS non-compliant with undefined REACH status. For applications subject to RoHS or REACH regulations, the Molex substitute is the appropriate selection.

Environmental Specifications: Both connectors maintain identical material flammability ratings (UL94 V-2), insulation color (natural), and moisture sensitivity levels (MSL 1 - Unlimited), ensuring equivalent performance in specified environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0353181220 directly replace the TE Connectivity 794511-1 in existing designs?

A: The Molex 0353181220 provides direct functional substitution based on identical mating pitch (0.165" / 4.20mm), position count (12), row configuration (2 rows), mounting type (through hole, right angle), shrouding design (4 wall), and termination method (solder). PCB footprints and mating interface dimensions are compatible.

Q: What are the differences in contact material between these connectors?

A: The TE Connectivity 794511-1 uses copper alloy contacts, while the Molex 0353181220 uses brass contacts. Both materials are suitable for solder termination and provide equivalent electrical conductivity for standard applications.

Q: Are there differences in contact finish specifications?

A: The TE Connectivity 794511-1 specifies tin-lead contact finish with 150.0µin (3.81µm) thickness on mating surfaces. The Molex 0353181220 specifies tin contact finish. Both finishes provide equivalent corrosion resistance and solderability for through-hole applications.

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

A: The TE Connectivity 794511-1 is RoHS non-compliant, while the Molex 0353181220 is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the Molex substitute is the appropriate selection. The Molex part eliminates lead and other restricted substances.

Q: Are the insulation materials functionally equivalent?

A: The TE Connectivity 794511-1 uses polyamide (PA) nylon, while the Molex 0353181220 uses polyamide (PA66) nylon 6/6. Both materials provide equivalent mechanical strength, thermal stability, and electrical insulation properties for the specified operating temperature range (-55°C ~ 105°C).

Q: What is the inventory status for each connector?

A: The TE Connectivity 794511-1 has 946 pieces in stock but is classified as obsolete with no future production. The Molex 0353181220 has 12,399 pieces in stock and maintains active product status, ensuring long-term availability for production and design requirements.

Q: Are there any differences in the contact post length specifications?

A: The TE Connectivity 794511-1 specifies contact post length of 0.138" (3.50mm). The Molex 0353181220 specifies contact post length of 0.173" (4.40mm). This difference accommodates varying PCB thicknesses and solder joint requirements. Verify PCB thickness compatibility during design integration.

Q: Do both connectors meet the same voltage and temperature specifications?

A: The TE Connectivity 794511-1 specifies 600VAC voltage rating and -55°C ~ 105°C operating temperature range. The Molex 0353181220 does not specify voltage rating or operating temperature range in the provided data. For applications requiring specific voltage or temperature ratings, verify Molex specifications against design requirements.
