Molex 0349619340 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0349619340 is a rectangular connector header designed for through-hole, right-angle board-to-cable/wire applications with 34 positions across 3 rows. This component features shrouded 4-wall construction with solder termination and latch lock fastening, commonly used in automotive applications. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the Molex 0349619340 is determined by strict alignment of the following electrical and mechanical parameters:

• Connector family and series: Mini50 34961 series maintains compatibility within the product line
• Position count and row configuration: 34 positions across 3 rows is the baseline requirement
• Mounting orientation: Through-hole, right-angle mounting must be preserved
• Shrouding design: 4-wall shrouded construction provides mechanical protection and alignment
• Termination method: Solder termination ensures compatibility with existing PCB layouts
• Contact configuration: Male blade contacts with rectangular shape
• Insulation material and height: SPS glass-filled insulation with 0.653"-0.654" height range
• Contact finish and material: Tin-plated contacts on copper alloy or brass base material

The Molex 0349619346 qualifies as a substitute based on these parameters. While it introduces minor variations in contact material (brass vs. copper alloy), pitch specification (0.079" mating pitch), and fastening mechanism (latch holder vs. latch lock), these differences remain within acceptable substitution boundaries for the Mini50 34961 series architecture.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0349619346 is the active-status substitute for the obsolete Molex 0349619340 within the Mini50 34961 connector series. Both components share the same fundamental architecture: 34-position, 3-row, through-hole right-angle headers with 4-wall shrouded construction and solder termination.

Selection of the 0349619346 is supported by its active product status, ensuring long-term availability and manufacturing consistency. The substitute introduces a defined mating pitch of 0.079" (2.00mm) and specifies operating temperature range (-40°C ~ 105°C) and voltage rating (14VDC), parameters not documented for the original part. The substitute also carries UL94 HB flammability certification.

Contact material differs between the two parts: the original uses copper alloy while the substitute uses brass. Both materials are tin-plated and suitable for solder termination. The fastening mechanism changes from latch lock to latch holder, representing a functional refinement within the same connector family.

For applications requiring exact reproduction of the original 0349619340 specifications, the 993 pieces currently in stock provide immediate availability. For new designs or long-term production requirements, the 0349619346 is the recommended path forward due to its active status and documented electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0349619346 directly replace the 0349619340 in existing PCB designs?

A: Yes. Both connectors maintain identical position count (34), row configuration (3), mounting type (through-hole right-angle), shrouding (4-wall), and termination method (solder). The 0.653" to 0.654" insulation height variance is negligible for PCB layout purposes. The contact post length (0.108") is identical. Verification of fastening mechanism compatibility (latch lock vs. latch holder) with mating connectors is required.

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

A: The 0349619346 specifies a mating pitch of 0.079" (2.00mm), which defines the center-to-center spacing between contact positions. This parameter was not documented for the original 0349619340. The pitch specification ensures proper alignment with mating connectors designed for the Mini50 34961 series.

Q: Does the contact material change from copper alloy to brass affect electrical performance?

A: Both copper alloy and brass are suitable conductor materials for tin-plated solder termination contacts. The brass material in the 0349619346 is also tin-plated, maintaining equivalent electrical conductivity and corrosion resistance for the specified 14VDC rating.

Q: Why does the substitute part show 32 positions loaded instead of all 34?

A: The 0349619346 specification indicates 32 positions loaded out of 34 total positions. This represents a configuration variation within the same connector family. Verification of position loading requirements for your specific application is necessary.

Q: Is the 0349619346 suitable for automotive applications?

A: The original 0349619340 is documented for automotive applications. The 0349619346 does not specify application category in the provided data. The substitute's operating temperature range (-40°C ~ 105°C) and UL94 HB flammability rating are consistent with automotive environmental requirements.

Q: What is the difference between latch lock and latch holder fastening types?

A: Both are mechanical fastening mechanisms within the Mini50 34961 series. Latch lock and latch holder represent design refinements for connector retention. Compatibility depends on the mating connector design. Verification with mating connector specifications is required.

Q: Are both parts RoHS compliant?

A: The 0349619340 is documented as ROHS3 compliant. RoHS status for the 0349619346 is not specified in the provided data. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.
