Substitute Part Grouping Explanation

Substitute parts for the Molex 0836149018 are identified based on strict alignment of electrical and mechanical parameters that determine functional interchangeability. The primary substitution criteria are:

Critical Parameters for Substitution:

• Connector style (D-Type, Micro-D)
• Connector type (Plug, Male Pins)
• Mounting type (Panel Mount, Through Hole, Right Angle)
• Shell size and pitch (0.050 Pitch x 0.050 Row to Row)
• Termination method (Solder)
• Shell material and finish (Steel, Nickel Plated)
• Contact finish (Gold, 15.0µin thickness)
• Current rating (1A)
• Flange feature (Mating Side, Female Screwlock 2-56)
• Dielectric material (Liquid Crystal Polymer)
• Contact material (Copper Alloy)
• Compliance certifications (UL94 V-0, RoHS3)

Substitute Parts Identified:

1. Molex 0836149012 – Full electrical and mechanical equivalent with identical 25-position configuration. Differs only in operating temperature range (-40°C to 125°C versus -55°C to 125°C) and packaging format (Tube). REACH status unaffected.

2. Molex 0836129020 – Parametric equivalent with reduced position count (15 positions versus 25 positions). Maintains all other critical parameters including connector style, mounting type, shell size, termination, materials, and compliance ratings. Packaging in Tube format. REACH status affected.

Parameter Comparison

Engineering Selection Recommendations

Molex 0836149012 is a direct substitute for the 0836149018 when the operating temperature minimum of -40°C meets application requirements. Both parts maintain identical electrical and mechanical specifications, including 25-position configuration, connector geometry, and material composition. Both are active products with full RoHS3 compliance and REACH unaffected status. Selection between these two parts depends solely on the lower temperature threshold requirement of the application.

Molex 0836129020 is a parametric equivalent suitable for applications requiring 15-position connectivity within the same connector family. This part maintains all critical electrical and mechanical parameters including connector style, mounting configuration, shell size, termination method, and material specifications. The 15-position configuration reduces the physical footprint while preserving the same pitch and row spacing. This part carries REACH affected status, which may require additional documentation in regulated supply chains.

Selection of substitute parts should be based on position count requirements and operating temperature specifications. All three parts maintain equivalent reliability, compliance, and performance characteristics within their specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0836149012 replace the 0836149018 in all applications?

A: The 0836149012 is a full electrical and mechanical equivalent with one exception: the operating temperature minimum is -40°C instead of -55°C. If your application operates above -40°C, the 0836149012 is a direct substitute. If operation below -40°C is required, the 0836149018 must be used.

Q: What is the primary difference between the 0836149018 and 0836129020?

A: The 0836129020 is a 15-position connector versus the 25-position configuration of the 0836149018. All other electrical and mechanical parameters remain equivalent, including connector style, mounting type, shell size, pitch, termination, materials, and compliance ratings. Selection depends on the number of signal connections required by the application.

Q: Are all three parts RoHS3 compliant?

A: Yes, all three parts are RoHS3 compliant. However, the 0836129020 carries REACH affected status, while both the 0836149018 and 0836149012 are REACH unaffected. This distinction may impact supply chain documentation requirements in certain regulated markets.

Q: Do the substitute parts use the same dielectric material and contact finish?

A: Yes. All three parts use Liquid Crystal Polymer (LCP) as the dielectric material and maintain gold contact finish at 15.0µin (0.38µm) thickness. The copper alloy contact material is identical across all variants.

Q: What is the significance of the shell size and pitch specification?

A: The 0.050 Pitch x 0.050 Row to Row specification defines the physical spacing of contacts within the connector. This parameter is identical across all three parts, ensuring mechanical compatibility with mating connectors and PCB layouts designed for the Micro-D form factor.

Q: Can these connectors be used interchangeably on the same PCB?

A: The 0836149018 and 0836149012 can be used interchangeably on the same PCB due to identical position count and connector geometry. The 0836129020, with its 15-position configuration, requires a different PCB footprint and cannot be directly substituted without layout modification.
