Key Parameters

Substitute Part Grouping Explanation

The Molex 0349617344 qualifies as a substitute for the 0349617341 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
• Insulation material: Syndiotactic Polystyrene (SPS), Glass Filled
• Contact finish: Tin (Mating and Post)
• Insulation height: 0.654" (16.61mm)
• Contact length - Post: 0.108" (2.75mm)
• Insulation color: Gray
• Series: Mini50 34961
• Base product number: 034961

Distinguishing Characteristics: The substitute part introduces a defined pitch specification of 0.079" (2.00mm) and provides additional operational parameters including operating temperature range (-40°C ~ 105°C), voltage rating (14VDC), and material flammability rating (UL94 HB). The substitute features a breakaway connector type option and includes contact length specification for mating (0.215" / 5.45mm). Contact material differs from copper alloy to brass, and fastening type transitions from latch lock to latch holder.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0349617344 is the primary substitute for the obsolete 0349617341. The substitute part maintains the same Mini50 34961 series designation and shares all critical mechanical and electrical interface parameters. The transition from the obsolete part to the active substitute is supported by:

• Active product status of the substitute, ensuring ongoing availability and manufacturing support
• Identical connector geometry, position count, and mounting configuration
• Matching insulation material and shrouding design
• Equivalent solder termination and tin contact finish specifications
• ROHS3 compliance maintained in the original part specification
• Identical ECCN and HTSUS classifications for regulatory and trade purposes

The substitute introduces defined operating parameters (temperature range -40°C ~ 105°C, 14VDC rating, UL94 HB flammability rating) and specifies a 0.079" (2.00mm) mating pitch. Contact material changes from copper alloy to brass, and fastening transitions from latch lock to latch holder. These differences reflect design evolution within the Mini50 series while preserving functional compatibility for board-to-cable/wire applications.

Frequently Asked Questions (FAQ)

Q: Can the 0349617344 directly replace the 0349617341 in existing designs?

A: The 0349617344 maintains identical position count (34), row configuration (3), mounting type (through hole, right angle), and insulation geometry. Both parts use the same Mini50 34961 series platform with shrouded 4-wall construction and solder termination. The substitute is suitable for applications requiring these core specifications.

Q: What is the significance of the pitch specification in the substitute part?

A: The 0349617344 specifies a mating pitch of 0.079" (2.00mm), which defines the center-to-center spacing between contact positions. This parameter was not specified for the original part but is a standard characteristic of the Mini50 34961 series. This specification ensures proper mating with corresponding connector receptacles designed for this pitch.

Q: How do the contact material differences affect performance?

A: The original part uses copper alloy contacts while the substitute uses brass contacts. Both materials are tin-finished for mating and post surfaces. Brass is a standard contact material in the Mini50 series and provides equivalent electrical conductivity and corrosion resistance when properly finished.

Q: What does the breakaway feature in the substitute part provide?

A: The 0349617344 includes breakaway connector capability, allowing individual positions to be separated if required. The original part does not specify this feature. This addition provides design flexibility without affecting the core 34-position, 3-row header functionality.

Q: Are there inventory considerations for this substitution?

A: The original part (0349617341) shows 841 pieces in stock with obsolete status. The substitute (0349617344) shows 905 pieces in stock with active product status. Active status ensures continued manufacturing and supply chain availability for future requirements.

Q: How do the fastening type differences impact installation?

A: The original part uses latch lock fastening while the substitute uses latch holder fastening. Both are mechanical retention methods for the Mini50 series. The specific fastening type should be verified against mating connector specifications to ensure compatibility with the receiving connector design.
