Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Molex 0349617342 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type classification (Header)
• Contact type (Male Blade)
• Position count (34 positions)
• Row configuration (3 rows)
• Mounting orientation (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Insulation material composition (Syndiotactic Polystyrene, Glass Filled)
• Physical dimensions (Insulation height 0.654", Contact post length 0.108")
• Contact finish specification (Tin)
• Series family (Mini50 34961)

The Molex 0349617345 qualifies as a manufacturer-recommended substitute within the Mini50 34961 series, maintaining identical position count, row configuration, mounting type, shrouding, and termination specifications. Both components share the same insulation material, height, and contact post length, ensuring mechanical and electrical compatibility in board-level applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0349617345 is the manufacturer-recommended substitute for the obsolete Molex 0349617342. Both components are classified within the same Mini50 34961 series and maintain identical mechanical and electrical interface specifications for 34-position, 3-row through-hole right-angle header applications.

The 0349617345 offers the advantage of active product status, ensuring continued availability and manufacturing support. The substitute provides specified operating temperature range (-40°C ~ 105°C) and voltage rating (14VDC) with UL94 HB flammability certification, supporting automotive and industrial applications. Contact material differs (brass versus copper alloy), though both materials with tin finish meet standard connector performance requirements.

Selection of the 0349617345 is appropriate for new designs and replacement applications requiring 34-position rectangular header connectors with through-hole right-angle mounting and solder termination in the Mini50 series family.

Frequently Asked Questions (FAQ)

Q: What makes the Molex 0349617345 a suitable substitute for the 0349617342?

A: Both components share identical specifications for position count (34), row configuration (3), mounting type (through-hole right-angle), shrouding (4-wall), termination method (solder), insulation material (SPS glass-filled), and physical dimensions (0.654" insulation height, 0.108" post length). Both are Mini50 34961 series connectors with male blade contacts and tin finish. The 0349617345 is the manufacturer-recommended replacement for the obsolete 0349617342.

Q: Are there differences in contact material between these parts?

A: Yes. The 0349617342 uses copper alloy contacts, while the 0349617345 uses brass contacts. Both materials are tin-finished and suitable for standard connector applications. Brass contacts in the 0349617345 provide equivalent electrical performance for the specified 14VDC rating.

Q: What is the difference between "Latch Lock" and "Latch Holder" fastening types?

A: The 0349617342 specifies latch lock fastening, while the 0349617345 specifies latch holder fastening. Both are retention mechanisms within the Mini50 series. Consult Molex technical documentation for specific mechanical engagement characteristics if fastening mechanism details are critical to your application.

Q: Can the 0349617345 be used in automotive applications?

A: The 0349617345 is suitable for automotive applications, supported by its UL94 HB flammability rating, -40°C ~ 105°C operating temperature range, and 14VDC voltage rating. The original 0349617342 was also specified for automotive use.

Q: What is the pitch specification for these connectors?

A: The 0349617342 does not specify pitch in the provided data. The 0349617345 specifies 0.079" (2.00mm) mating pitch. Both components maintain identical 34-position, 3-row configuration within the Mini50 34961 series.

Q: Are both parts RoHS compliant?

A: The 0349617342 is confirmed ROHS3 compliant. RoHS compliance status for the 0349617345 is not specified in the provided data. Consult Molex documentation for complete RoHS certification details for the substitute part.
