• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Finish - Mating: Gold
• Fastening Type: Push-Pull
• Insulation Material: Polyester or Glass Filled composition
• Contact Material: Phosphor Bronze

Allowable Variations:

• Product Status: Active status is acceptable for obsolete parts
• Contact Finish - Post: Variations in post finish composition and thickness are permissible
• Operating Temperature Range: Substitute parts with equal or extended temperature ranges are acceptable
• Contact Finish Thickness - Mating: Minor variations in gold plating thickness are acceptable within industry standards
• Insulation Height and Contact Length: Minor dimensional variations within tolerance are acceptable

The identified substitute parts meet these criteria and provide functional equivalence for the 146139-9.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5146139-9: This part is the direct successor to the 146139-9 within the same AMPMODU Mod II series. It maintains identical mechanical and electrical specifications while offering active product status. The 5146139-9 is RoHS Compliant, addressing regulatory requirements for new designs. The primary difference is the post finish composition (Tin versus Tin-Lead) and increased post finish thickness (150.0µin versus 50.0µin), which provides enhanced durability and solderability. This part is the preferred selection for applications requiring regulatory compliance and continued manufacturer support.

Molex 0901481210: This part provides cross-manufacturer equivalence with full functional compatibility. The 0901481210 operates within a reduced temperature range (-55°C to 105°C) compared to the 146139-9 (-55°C to 125°C), making it suitable for applications not requiring the extended upper temperature limit. The part is ROHS3 Compliant and carries active product status. Insulation material composition includes PBT in addition to polyester and glass fill, offering alternative material properties. This connector is applicable to automotive, general purpose, lighting, medical, and telecommunications applications. Selection of this part is appropriate when cross-manufacturer sourcing is required or when the reduced temperature range is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can the 146139-9 be directly replaced with the 5146139-9?

A: Yes. The 5146139-9 is a direct functional equivalent with identical connector geometry, pitch, position count, and mounting configuration. Both parts are from the same AMPMODU Mod II series. The 5146139-9 offers the advantage of active product status and RoHS compliance. The post finish composition differs (Tin versus Tin-Lead), but this does not affect mating compatibility or electrical performance.

Q: What is the temperature limitation when using the Molex 0901481210 as a substitute?

A: The Molex 0901481210 operates across -55°C to 105°C, whereas the 146139-9 operates across -55°C to 125°C. Applications requiring operation above 105°C must use either the 146139-9 or the 5146139-9. For applications with maximum operating temperatures at or below 105°C, the Molex part is fully suitable.

Q: Are there packaging differences between these substitute parts?

A: The 146139-9 and 5146139-9 do not specify packaging information in the provided data. The Molex 0901481210 is supplied in Tube packaging. Packaging format should be confirmed with the supplier based on procurement requirements.

Q: Do all three parts meet RoHS requirements?

A: The 146139-9 has RoHS status listed as "Not applicable." The 5146139-9 is RoHS Compliant. The 0901481210 is ROHS3 Compliant. For applications requiring RoHS compliance, either the 5146139-9 or 0901481210 must be selected.

Q: What are the differences in contact finish specifications?

A: All three parts feature gold-plated mating contacts. The 146139-9 has 10.0µin (0.25µm) gold thickness with tin-lead post finish at 50.0µin (1.27µm). The 5146139-9 has 10.0µin (0.25µm) gold thickness with tin post finish at 150.0µin (3.81µm). The 0901481210 has 15.0µin (0.38µm) gold thickness with tin post finish at 118.1µin (3.00µm). These variations are within acceptable industry standards for equivalent connectors.

Q: Are the mechanical dimensions identical across all three parts?

A: Dimensions are substantially equivalent with minor variations. Insulation height differs slightly: 146139-9 and 5146139-9 are 0.137" (3.47mm), while the 0901481210 is 0.130" (3.30mm). Contact length post dimensions are 0.115" (2.92mm) for 146139-9 and 5146139-9, and 0.114" (2.90mm) for the 0901481210. These dimensional variations are within typical manufacturing tolerances and do not affect functional compatibility in standard board-to-board applications.

Q: Which substitute part should be selected for new designs?

A: The TE Connectivity 5146139-9 is the recommended selection for new designs. It maintains the same series lineage as the obsolete 146139-9, offers active product status with manufacturer support, and provides RoHS compliance. The Molex 0901481210 is appropriate when cross-manufacturer sourcing is required or when the reduced temperature range is acceptable for the application.
