Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0349610342 is determined by the following critical parameters:

• Connector type and form factor (Header, through-hole, right-angle orientation)
• Position count and row configuration (34 positions, 3 rows)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Mounting style (Board to Cable/Wire)
• Physical dimensions (Insulation height, contact post length)
• Material composition and finish specifications
• Regulatory compliance (RoHS3, REACH)

The substitute part Molex 0349610345 maintains compatibility within the Mini50 34961 series and preserves the core mechanical and electrical interface characteristics required for direct substitution in existing applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0349610345 is the designated manufacturer substitute for the obsolete 0349610342. Both components share identical mechanical interfaces, dimensional specifications, and core electrical characteristics within the Mini50 34961 series. The substitute part offers the advantage of active product status with documented operating temperature range (-40°C ~ 105°C), voltage rating (14VDC), and material flammability certification (UL94 HB), providing enhanced specification documentation for design validation and compliance verification. Both parts maintain ROHS3 compliance and REACH unaffected status. The substitute's breakaway connector feature provides additional design flexibility without compromising interface compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 0349610345 directly replace the 0349610342 in existing applications?

A: Yes. Both components maintain identical 34-position, 3-row configuration, through-hole right-angle mounting, shrouded 4-wall construction, and solder termination. Physical dimensions and contact specifications are equivalent, enabling direct substitution in existing PCB layouts and mating connector assemblies.

Q: What is the primary difference between these two parts?

A: The 0349610342 is obsolete with limited specification documentation, while the 0349610345 is an active product with complete operating parameters including temperature range (-40°C ~ 105°C), voltage rating (14VDC), and flammability rating (UL94 HB). The 0349610345 also features breakaway connector capability.

Q: Are there packaging differences between these parts?

A: The 0349610342 packaging is not specified in available documentation. The 0349610345 is supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 0349610342 and 0349610345 are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.

Q: What contact material is used in each part?

A: The 0349610342 uses Copper Alloy contacts, while the 0349610345 uses Brass contacts. Both are tin-finished and suitable for solder termination applications.

Q: Is the fastening mechanism the same on both parts?

A: The 0349610342 uses Latch Lock fastening, while the 0349610345 uses Latch Holder fastening. Both provide secure mating interface retention appropriate for board-to-cable/wire applications.
