Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0349611343 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Manufacturer: Molex
• Series: MINI50 (034961 base product family)
• Number of Positions: 34
• Number of Positions Loaded: 18
• Pitch - Mating: 0.079" (2.00mm)
• Contact Type: Male Blade; Male Pin
• Termination: Solder
• Voltage Rating: 14VDC
• Operating Temperature Range: -40°C ~ 105°C
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part must maintain identical electrical performance characteristics and physical dimensions to ensure direct replacement capability in existing circuit board designs and mating connector applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0349611349 is the direct substitute for the obsolete Molex 0349611343. Both parts share identical electrical and mechanical specifications across all critical parameters: 34-position configuration with 18 positions loaded, 0.079" (2.00mm) pitch, male blade pin contact type, solder termination, 14VDC voltage rating, and -40°C to 105°C operating temperature range.

The primary distinction is product status: the 0349611343 is obsolete, while the 0349611349 is active. The substitute part incorporates additional design features including right-angle mounting orientation, breakaway connector capability, 4-wall shrouding, and specified material certifications (UL94 HB flammability rating). These enhancements provide improved mechanical robustness and electromagnetic shielding without altering the core electrical interface.

Selection of the 0349611349 eliminates obsolescence risk and ensures continued component availability for production and field service applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0349611349 directly replace the 0349611343 in existing designs?

A: Yes. Both parts maintain identical electrical and mechanical specifications for the 34-position, 18-loaded configuration with 0.079" (2.00mm) pitch and male blade pin contacts. The primary difference is the mounting orientation: the 0349611349 features right-angle through-hole mounting compared to the standard through-hole configuration of the 0349611343. Design verification is required to confirm mounting orientation compatibility with the circuit board layout.

Q: What is the significance of the "Breakaway" feature on the 0349611349?

A: The breakaway feature allows individual connector sections to be separated from the main header assembly. This provides design flexibility for applications requiring modular connector configurations or selective position utilization.

Q: Does the 4-wall shrouding on the 0349611349 affect mating compatibility?

A: The 4-wall shrouding provides mechanical guidance and protection during mating operations. Compatibility depends on the mating connector design. Verify that the mating connector accommodates the shrouded header geometry.

Q: Are there any differences in electrical performance between these parts?

A: No. Both parts operate at 14VDC with identical contact materials (brass), contact finishes (tin), and temperature ratings (-40°C to 105°C). Electrical performance is equivalent.

Q: What does MSL 1 (Unlimited) indicate?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts carry this classification.

Q: Is the right-angle mounting of the 0349611349 a limitation?

A: Right-angle mounting is a design feature, not a limitation. It is suitable for applications where the connector must be mounted perpendicular to the circuit board surface. Standard through-hole mounting applications may require board layout modification to accommodate this orientation.
