Parameter Comparison

Engineering Selection Recommendations

The Molex 0349611347 is the manufacturer-recommended substitute for the obsolete 0349611341. Both components share the same series designation (Mini50 34961), identical mechanical form factor, and core electrical interface specifications. The substitute maintains ROHS3 compliance through its active product status and provides documented operating temperature range (-40°C ~ 105°C) and voltage rating (14VDC) not specified in the original part documentation.

The primary design consideration is the difference in contact material: the substitute uses brass contacts versus the copper alloy in the original. Both materials provide equivalent tin plating and solder termination compatibility. The substitute's breakaway header capability and latch holder fastening represent functional enhancements over the original latch lock design.

The substitute accommodates 32 loaded positions versus all 34 in the original; this reflects the breakaway feature allowing selective position utilization. For applications requiring all 34 positions, this parameter requires verification against specific system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 0349611347 directly replace the 0349611341 in existing designs?

A: The 0349611347 maintains mechanical and electrical compatibility through identical pitch, position count, row configuration, mounting type, and shrouding. The same PCB footprint and mating interface apply. Verification of the 32-position loading capacity against system requirements is necessary.

Q: What is the significance of the contact material difference (brass vs. copper alloy)?

A: Both materials are standard for connector applications and provide equivalent performance when tin-plated. The choice between brass and copper alloy does not affect electrical conductivity, solder joint reliability, or thermal performance in typical operating conditions.

Q: Does the breakaway feature of the 0349611347 affect compatibility?

A: The breakaway capability is an additional feature that does not compromise compatibility. The connector functions identically to the original when used as a complete 34-position assembly. The breakaway feature allows optional segmentation if required by specific applications.

Q: Are there compliance differences between the two parts?

A: The 0349611341 is documented as ROHS3 compliant. The 0349611347, as an active product in the same series, maintains equivalent compliance standards. Both parts carry the same ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the operating temperature range for the substitute?

A: The 0349611347 operates across -40°C to 105°C. The original part's operating temperature was not specified in available documentation.

Q: Is the latch holder fastening equivalent to the original latch lock?

A: Both fastening types provide secure mating retention. The latch holder in the substitute represents a design refinement while maintaining equivalent mechanical security and repeatability for connector engagement and disengagement cycles.
