Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type (Header)
• Contact Type (Male Pin)
• Number of Positions (4)
• Number of Rows (1)
• Pitch - Mating (0.250" / 6.35mm)
• Mounting Type (Through Hole)
• Termination (Solder)
• Shrouding (Shrouded - 4 Wall)
• Fastening Type (Locking Ramp)
• Contact Material (Phosphor Bronze)
• Insulation Material (Polyamide/Nylon)
• Style (Board to Cable/Wire)
• Series (Universal MATE-N-LOK)

Variable Parameters Permitting Substitution:

• Packaging configuration (Bulk vs. standard)
• Contact finish specifications (Gold vs. Tin on mating surface)
• Insulation color (Natural vs. White)
• Material flammability rating (UL94 V-2 vs. UL94 V-0)
• RoHS compliance status

All identified substitute parts maintain identical mechanical dimensions, electrical interface characteristics, and functional performance within the Universal MATE-N-LOK connector ecosystem.

Parameter Comparison

Engineering Selection Recommendations

350430-4 (Direct Substitute)

Part 350430-4 is a direct functional equivalent to 350430-2 with identical electrical and mechanical specifications. The primary distinction is RoHS compliance status: 350430-4 is RoHS Compliant, whereas 350430-2 is RoHS non-compliant. Selection of 350430-4 is appropriate for applications subject to RoHS regulatory requirements or when compliance with environmental standards is mandated. Packaging is supplied in Bulk configuration. All other parameters, including contact finish specifications (Gold mating surface, 30.0µin thickness), insulation properties, and dimensional characteristics, are identical.

350430-1 (Functional Equivalent with Contact Finish Variation)

Part 350430-1 maintains full mechanical and electrical compatibility with 350430-2 and is RoHS Compliant. The contact finish on the mating surface differs: 350430-1 features Tin plating instead of Gold. This variation does not affect mechanical mating or electrical performance within the Universal MATE-N-LOK series. Selection of 350430-1 is appropriate when RoHS compliance is required and tin-plated mating surfaces are acceptable for the application. Packaging is supplied in Bulk configuration.

350792-1 (Functional Equivalent with Enhanced Flammability Rating)

Part 350792-1 is mechanically and electrically compatible with 350430-2 and is RoHS Compliant. Notable differences include: (1) Material flammability rating of UL94 V-0 compared to UL94 V-2 on the main part, providing enhanced flame resistance; (2) Insulation color is White instead of Natural; (3) Contact finish on mating surface is Tin instead of Gold; (4) Base product number is 350792 rather than 350430. Selection of 350792-1 is appropriate for applications requiring enhanced flammability performance or when white insulation color is specified. Packaging is supplied in Bulk configuration with highest inventory availability.

All substitute parts are Active product status and maintain MSL Level 1 (Unlimited) moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can 350430-4 be used as a direct replacement for 350430-2?

A: Yes. Part 350430-4 is electrically and mechanically identical to 350430-2. The primary difference is RoHS compliance status. If the application does not require RoHS compliance, both parts are functionally interchangeable. If RoHS compliance is mandated, 350430-4 is the appropriate selection.

Q: What is the significance of the contact finish difference between 350430-2 and 350430-1?

A: The main part 350430-2 features gold-plated mating contacts (30.0µin thickness), while 350430-1 features tin-plated mating contacts. Both finishes provide adequate electrical conductivity and corrosion resistance within the Universal MATE-N-LOK connector system. The choice between gold and tin plating is determined by application requirements and cost considerations. Tin plating is suitable for general-purpose applications with standard environmental conditions.

Q: Is 350792-1 compatible with existing 350430-2 installations?

A: Yes. Part 350792-1 maintains identical mechanical dimensions, pitch spacing (0.250"), mounting type (through-hole), and electrical interface characteristics. The connector will mate and function identically with existing mating connectors. Differences in insulation color (White vs. Natural) and flammability rating (UL94 V-0 vs. UL94 V-2) do not affect mechanical or electrical compatibility.

Q: Why would I select 350792-1 over 350430-4?

A: Selection of 350792-1 is appropriate when enhanced flammability performance is required. The UL94 V-0 rating on 350792-1 indicates superior flame resistance compared to the UL94 V-2 rating on 350430-4. Applications in safety-critical systems, high-temperature environments, or those subject to stringent flammability standards should specify 350792-1. Additionally, 350792-1 offers the highest inventory availability (4100 pcs).

Q: Are all substitute parts available in the same packaging as the main part?

A: No. The main part 350430-2 is supplied in standard packaging, while all substitute parts (350430-4, 350430-1, and 350792-1) are supplied in Bulk packaging. Bulk packaging typically contains larger quantities per unit. Verify packaging requirements with procurement specifications before selection.

Q: What is the difference between the 350430 and 350792 base product numbers?

A: The base product number identifies the connector family and design variant. Part 350792-1 uses base product number 350792, while 350430-2, 350430-4, and 350430-1 use base product number 350430. Both families are within the Universal MATE-N-LOK series and are mechanically and electrically compatible. The different base numbers reflect design generation or manufacturing source variations.

Q: Are all substitute parts RoHS Compliant?

A: The main part 350430-2 is RoHS non-compliant. All three substitute parts (350430-4, 350430-1, and 350792-1) are RoHS Compliant. If RoHS compliance is a design requirement, any of the three substitute parts is acceptable.

Q: Do all parts have the same moisture sensitivity level?

A: Yes. All parts, including the main part 350430-2 and all substitutes, are classified as MSL Level 1 (Unlimited). This indicates no moisture sensitivity restrictions during storage or handling.
