Key Parameters

Substitute Part Grouping Explanation

The Molex 0349610343 qualifies as a direct substitute for the 0349610340 based on the following critical parameters that determine functional compatibility:

Matching Parameters:

• Manufacturer and Series: Both are Molex Mini50 34961 series components
• Connector Configuration: Both are 34-position, 3-row headers with male blade contacts
• Mounting and Orientation: Both feature through-hole, right-angle mounting
• Shrouding: Both utilize shrouded 4-wall construction
• Termination Method: Both employ solder termination
• Insulation Material and Height: Identical SPS glass-filled insulation at 0.654" (16.61mm)
• Contact Post Length: Both maintain 0.108" (2.75mm) post length
• Contact Finish: Both use tin-plated contacts
• Compliance: Both are ROHS3 compliant and REACH unaffected

Distinguishing Parameters:

• Product Status: The substitute (0349610343) is active, whereas the main part is obsolete
• Fastening Type: Substitute uses latch holder versus latch lock on the main part
• Contact Material: Substitute uses brass versus copper alloy on the main part
• Pitch - Mating: Substitute specifies 0.079" (2.00mm) pitch
• Contact Length - Mating: Substitute specifies 0.215" (5.45mm)
• Operating Temperature: Substitute rated -40°C ~ 105°C
• Voltage Rating: Substitute rated 14VDC
• Current Rating: Substitute varies by wire gauge
• Material Flammability: Substitute rated UL94 HB
• Connector Type: Substitute includes breakaway capability

Parameter Comparison

Engineering Selection Recommendations

The Molex 0349610343 is the manufacturer-recommended substitute for the obsolete 0349610340. Both components maintain identical mechanical and electrical interface specifications across the critical parameters that define connector compatibility: position count, row configuration, mounting orientation, shrouding design, and post dimensions.

The substitute part carries active product status with full ROHS3 compliance and REACH unaffected certification, ensuring regulatory alignment for current manufacturing and procurement cycles. The addition of breakaway capability and latch holder fastening in the substitute provides enhanced design flexibility without compromising backward compatibility with existing mating interfaces.

The transition from copper alloy to brass contact material and the inclusion of defined operating temperature range (-40°C ~ 105°C) and voltage rating (14VDC) in the substitute reflect current automotive connector standards and provide improved performance documentation for system design validation.

Frequently Asked Questions (FAQ)

Q: Can the 0349610343 directly replace the 0349610340 in existing applications?

A: Yes. Both connectors maintain identical position count (34), row configuration (3), mounting type (through-hole right-angle), shrouding (4-wall), and post dimensions (0.108" / 2.75mm). The mating interface is compatible. The fastening type difference (latch holder versus latch lock) affects retention mechanism but does not prevent functional substitution.

Q: What is the significance of the breakaway feature in the substitute part?

A: The breakaway capability in the 0349610343 allows individual positions to be separated if required, providing design flexibility not present in the original part. This feature does not affect standard connector operation when used as a complete 34-position assembly.

Q: Are there packaging differences between these parts?

A: The main part (0349610340) packaging is not specified in the technical data. The substitute (0349610343) is supplied in tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: How do the contact material differences affect performance?

A: The main part uses copper alloy contacts; the substitute uses brass contacts. Both are tin-plated and suitable for automotive applications. Brass provides enhanced corrosion resistance and is standard in current Molex Mini50 series production.

Q: Is the substitute part suitable for automotive applications?

A: Yes. The 0349610343 is rated for automotive use with operating temperature range -40°C ~ 105°C and 14VDC voltage rating, meeting automotive connector performance requirements.

Q: What inventory status should I consider for procurement?

A: The main part (0349610340) has 813 pieces in stock but is obsolete. The substitute (0349610343) has 1694 pieces in stock and active product status, making it the recommended choice for new designs and ongoing supply continuity.
