Substitute Part Grouping Explanation

Substitution of the Molex 0440681003 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (18)
• Number of rows (2)
• Mating pitch (0.165" / 4.20mm)
• Row spacing (0.165" / 4.20mm)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact finish specifications (Gold mating, Tin post)
• Insulation material (Polyamide PA46, Nylon 4/6)
• Flammability rating (UL94 V-0)
• Series compatibility (Mini-Fit BMI SMC 44068)

The substitute part 0440680041 maintains full electrical and mechanical compatibility across all specified parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0440680041 is the direct equivalent for the obsolete 0440681003. Both parts are manufactured by Molex within the same Mini-Fit BMI SMC 44068 series and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product status: 0440681003 is obsolete, while 0440680041 is active. This transition reflects standard component lifecycle management and ensures continued supply chain access for new designs and production requirements.

Both parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial, medical, and telecommunications applications. The UL94 V-0 flammability rating is maintained across both variants.

Frequently Asked Questions (FAQ)

Q: Can 0440680041 be used as a direct replacement for 0440681003?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including connector type, position count, pitch, shrouding, contact finishes, and material specifications. The substitute is recommended for new production due to active product status.

Q: What is the difference between these two part numbers?

A: The primary difference is product lifecycle status. 0440681003 is obsolete, while 0440680041 is active. Packaging differs (0440680041 is supplied in Tray format), but all functional and electrical characteristics remain identical.

Q: Are there any compatibility concerns when switching from 0440681003 to 0440680041?

A: No compatibility concerns exist. Both parts conform to the same series specification, pitch, row spacing, mounting method, and contact configuration. PCB layouts and mating connector designs require no modification.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both 0440681003 and 0440680041 are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability ratings. MSL rating is 1 (Unlimited) for both variants.

Q: What applications are these connectors suitable for?

A: Both parts are specified for General Purpose, Industrial, Medical, and Telecommunications applications. The through-hole mounting and shrouded 4-wall design provide robust performance in board-to-board and cable interconnect scenarios.

Q: Is the packaging difference significant?

A: Packaging format (Tray for 0440680041) affects handling and storage but does not impact electrical or mechanical performance. Tray packaging is standard for active production components and facilitates automated assembly processes.
