Parameter Comparison

Engineering Selection Recommendations

350428-4: This part is functionally equivalent to 350428-2 with identical electrical and mechanical specifications. The primary distinction is RoHS compliance status. Part 350428-4 is RoHS Compliant, whereas 350428-2 is RoHS Non-Compliant. Selection of 350428-4 is appropriate for applications requiring RoHS compliance or when inventory of the main part is unavailable. Packaging is provided in bulk format.

350428-1: This part maintains full mechanical and electrical compatibility with 350428-2. The contact finish on the mating surface differs: 350428-1 features tin plating instead of gold plating. This part carries ROHS3 Compliant certification. Selection is appropriate for applications where tin-plated mating surfaces are acceptable and RoHS3 compliance is required.

350786-1: This part shares the same mechanical interface and connector family designation as 350428-2. Differences include contact material (Phosphor Bronze instead of Copper Alloy), mating surface finish (Tin instead of Gold), insulation color (White instead of Natural), and material flammability rating (UL94 V-0 instead of UL94 V-2). This part is RoHS Compliant. Selection is appropriate for applications requiring enhanced flammability performance or where Phosphor Bronze contact material is specified.

All substitute parts maintain identical pitch, position count, mounting type, and shrouding configuration, ensuring direct mechanical and electrical interchangeability in board-to-cable/wire applications.

Frequently Asked Questions (FAQ)

Q: Can 350428-4 be used as a direct replacement for 350428-2?

A: Yes. Both parts are identical in connector type, contact configuration, pitch, mounting method, and mechanical dimensions. The primary difference is RoHS compliance status. 350428-4 is RoHS Compliant while 350428-2 is RoHS Non-Compliant. Electrical and mechanical performance are equivalent.

Q: What is the difference between the gold-plated and tin-plated mating surfaces?

A: The main part 350428-2 features gold-plated mating contacts (30.0µin thickness), while 350428-1 and 350786-1 feature tin-plated mating contacts. Both finishes provide electrical conductivity and corrosion resistance. The selection between them depends on application requirements and compatibility with mating connector specifications.

Q: Is 350786-1 compatible with applications designed for 350428-2?

A: 350786-1 maintains full mechanical compatibility and identical connector interface specifications. The contact material differs (Phosphor Bronze versus Copper Alloy) and the flammability rating is higher (UL94 V-0 versus UL94 V-2). These differences do not affect mechanical interchangeability but may be relevant for specific application requirements.

Q: What does RoHS compliance mean for connector selection?

A: RoHS compliance indicates the part meets Restriction of Hazardous Substances regulations. 350428-2 is RoHS Non-Compliant, while 350428-4, 350428-1, and 350786-1 are RoHS Compliant or ROHS3 Compliant. Selection depends on regulatory requirements for the end application or geographic market.

Q: Are all substitute parts available in the same packaging format?

A: No. The main part 350428-2 packaging is not specified in detail. Substitute parts 350428-4, 350428-1, and 350786-1 are available in bulk packaging. Packaging format should be confirmed based on procurement requirements.

Q: Can these connectors be used interchangeably in the same circuit board design?

A: Yes, all parts maintain identical mechanical dimensions, pitch, mounting type, and electrical interface. They are mechanically and electrically interchangeable in board-to-cable/wire applications within the Universal MATE-N-LOK connector family. Design verification should confirm that contact finish and material specifications align with mating connector requirements.

Q: What is the significance of the UL94 V-0 rating on 350786-1?

A: UL94 V-0 is a higher flammability classification than UL94 V-2. This indicates enhanced flame resistance. Selection of 350786-1 is appropriate for applications with stringent flammability requirements or where UL94 V-0 certification is specified.
