Key Parameters

Substitute Part Grouping Explanation

The Molex 0349611346 qualifies as a substitute for the 0349611340 based on the following alignment of critical parameters:

Matching Parameters:

• Connector Type: Header (with breakaway capability in substitute)
• Contact Type: Male Blade
• Number of Positions: 34
• Number of Rows: 3
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Contact Length - Post: 0.108" (2.75mm)
• Insulation Height: 0.654" (16.61mm)
• Insulation Material: Syndiotactic Polystyrene (SPS), Glass Filled
• Series: Mini50 34961
• Pitch - Mating: 0.079" (2.00mm)

Differing Parameters:

• Contact Material: Brass (substitute) vs. Copper Alloy (original)
• Number of Positions Loaded: 32 (substitute) vs. All (original)
• Fastening Type: Latch Holder (substitute) vs. Latch Lock (original)
• Product Status: Active (substitute) vs. Obsolete (original)

The substitute maintains dimensional compatibility, electrical interface consistency, and mechanical mounting characteristics necessary for direct replacement in board-to-cable/wire applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0349611346 is the manufacturer-recommended substitute for the obsolete 0349611340. Both components share the same series designation (Mini50 34961) and maintain identical mechanical and dimensional specifications critical to PCB mounting and mating interface compatibility.

The substitute offers the advantage of active product status, ensuring continued availability and manufacturing support. The 0349611346 provides specified operating temperature range (-40°C ~ 105°C) and voltage rating (14VDC), parameters not documented for the original part. These specifications align with automotive application requirements.

Material composition differs between the parts: the substitute uses brass contacts versus copper alloy in the original. Both materials provide equivalent electrical conductivity and tin plating ensures consistent solder joint reliability. The substitute's reduced position loading (32 of 34 positions) and latch holder fastening mechanism represent design refinements within the same connector family.

Frequently Asked Questions (FAQ)

Q: Can the 0349611346 directly replace the 0349611340 in existing designs?

A: Yes. Both connectors maintain identical pitch spacing, row configuration, mounting orientation, and PCB footprint. The 34-position, 3-row through-hole right-angle header geometry is preserved. Mating interface compatibility is ensured through matching shrouded 4-wall construction and solder termination specifications.

Q: What is the significance of the difference in positions loaded (32 vs. All)?

A: The original 0349611340 loads all 34 positions with contacts. The substitute 0349611346 loads 32 of 34 positions. This difference reflects design optimization within the Mini50 34961 series. Verify your application's actual contact utilization to confirm compatibility.

Q: How do the contact material differences affect performance?

A: The original uses copper alloy contacts; the substitute uses brass. Both materials provide adequate electrical conductivity for signal and power distribution in automotive applications. Tin plating on both ensures reliable solder joint formation and corrosion resistance. Material selection does not impact electrical performance for standard connector applications.

Q: Are there compliance differences between these parts?

A: The original 0349611340 is documented as ROHS3 Compliant. The substitute 0349611346 does not specify RoHS status in the provided data. Both are manufactured by Molex within the same product series and share identical insulation materials (SPS, glass-filled). Verify RoHS compliance requirements for your specific application and supply chain.

Q: What is the breakaway feature in the substitute?

A: The 0349611346 is designated as a "Header, Breakaway" type. This indicates the connector supports modular configuration options within the Mini50 34961 series. The core 34-position, 3-row header functionality remains unchanged for standard applications.

Q: Are there inventory or lead time considerations?

A: The original 0349611340 is obsolete with 731 pieces in stock. The substitute 0349611346 is active with 729 pieces in stock. For new designs or long-term production, the active substitute ensures ongoing availability and manufacturing continuity.
