Parameter Comparison

Engineering Selection Recommendations

350711-4 (Direct Substitute)

The 350711-4 is a direct functional equivalent to the 350711-2. Both parts share identical electrical and mechanical specifications, including the same contact finish (Gold mating surface with 30.0µin thickness), flammability rating (UL94 V-0), and row configuration (3 rows). The primary distinction is that 350711-4 carries ROHS3 compliance certification, whereas 350711-2 is RoHS non-compliant. Selection of 350711-4 is appropriate when RoHS3 compliance is required for the application or end-use market.

350711-1 (Functional Equivalent with Compliance Upgrade)

The 350711-1 maintains the same mechanical configuration and flammability rating (UL94 V-0) as the main part but differs in contact finish specification. The mating contact finish changes from Gold to Tin, and the contact finish thickness specification is not provided. The 350711-1 carries ROHS3 compliance. This part is suitable for applications where RoHS3 compliance is mandatory and where tin-plated contacts are acceptable for the intended electrical environment.

350431-1 (Functional Equivalent with Modified Specifications)

The 350431-1 maintains the 3-row configuration and core mechanical parameters but introduces two specification changes: the mating contact finish is Tin (rather than Gold), and the material flammability rating is UL94 V-2 (rather than UL94 V-0). The part carries ROHS3 compliance. Selection of 350431-1 is appropriate when RoHS3 compliance is required and when the UL94 V-2 flammability rating meets application requirements.

641832-1 (Functional Equivalent with Dimensional and Electrical Variations)

The 641832-1 differs from the main part in row configuration (1 row instead of 3 rows), insulation color (White instead of Natural), and includes specified operating temperature (-40°C ~ 105°C), current rating (12A), and voltage rating (600VAC). The mating contact finish is Tin, and the flammability rating is UL94 V-2. The part carries ROHS3 compliance. Selection of 641832-1 is appropriate when a single-row configuration is required and when the specified electrical ratings and operating temperature range are compatible with the application.

Frequently Asked Questions (FAQ)

Q: Can 350711-4 be used as a direct replacement for 350711-2?

A: Yes. The 350711-4 is electrically and mechanically identical to 350711-2. Both parts feature 6 positions, 0.250" pitch, 3-row configuration, gold-plated mating contacts with 30.0µin thickness, UL94 V-0 flammability rating, and identical insulation specifications. The primary difference is that 350711-4 carries ROHS3 compliance certification.

Q: What is the key difference between 350711-2 and 350711-1?

A: Both parts share the same mechanical configuration (6 positions, 0.250" pitch, 3 rows, UL94 V-0 rating). The difference is in contact finish: 350711-2 features gold-plated mating contacts, while 350711-1 features tin-plated mating contacts. Additionally, 350711-1 carries ROHS3 compliance.

Q: Why does 350431-1 have a different flammability rating?

A: The 350431-1 is specified with UL94 V-2 flammability rating instead of UL94 V-0. This represents a different material formulation for the insulation. Both ratings are valid for general-purpose applications; the selection depends on specific application requirements for flame resistance.

Q: Is 641832-1 compatible with applications designed for 350711-2?

A: Mechanical compatibility exists only if the application accommodates a single-row configuration instead of three rows. The 641832-1 maintains the same 0.250" pitch and connector type but differs in physical layout. Additionally, 641832-1 includes specified electrical ratings (12A at 600VAC) and operating temperature range (-40°C ~ 105°C), which should be verified against application requirements.

Q: What does the packaging difference mean?

A: The main part 350711-2 does not specify a packaging format, while all substitute parts are listed as Bulk packaging. This indicates that substitute parts are supplied in bulk quantities rather than in alternative packaging configurations. Verify that bulk packaging is acceptable for procurement and handling requirements.

Q: Can I use a tin-plated contact version instead of gold-plated?

A: Tin-plated contacts (350711-1, 350431-1, 641832-1) can be used in applications where the electrical environment does not require gold plating. Gold plating provides superior corrosion resistance and is typically specified for low-signal applications or harsh environments. Tin plating is suitable for general-purpose applications with standard environmental conditions. Verify application requirements before substitution.

Q: Are all substitute parts RoHS compliant?

A: The main part 350711-2 is RoHS non-compliant. All substitute parts (350711-4, 350431-1, 350711-1, 641832-1) carry ROHS3 compliance certification. If RoHS compliance is required, any of the substitute parts are suitable.

Q: What is the significance of the row configuration difference in 641832-1?

A: The 641832-1 features a single-row configuration (1 row) compared to the 3-row configuration of 350711-2. This affects the physical footprint and mating interface. The 641832-1 is suitable only for applications specifically designed for single-row headers with 0.250" pitch spacing.
