Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0901200774 are qualified based on the following critical parameters that must align with the original specification:

Mandatory Matching Parameters:

• Number of Positions: 14
• Pitch - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Connector Style: Board to Board or Cable
• Shrouding: Unshrouded

Acceptable Variation Parameters:

• Connector Type: Header variants (Breakaway, Cuttable)
• Contact Finish - Mating: Gold or Tin (both acceptable for 2.54mm pitch headers)
• Insulation Material: Polyester Glass Filled, Polybutylene Terephthalate (PBT), or Polyamide (PA6T)
• Operating Temperature Range: Must encompass or match the -55°C to 125°C range
• Contact Material: Brass or Copper Alloy
• Material Flammability: UL94 V-0 required

The four substitute parts identified (A2-14PA-2.54DSA(71), M20-9991445, M20-9991446, and 4-103185-0) meet these core criteria, though 4-103185-0 differs in position count and is listed for reference only.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (14-Position, Direct Equivalents):

The Hirose A2-14PA-2.54DSA(71), Harwin M20-9991445, and Harwin M20-9991446 are direct functional equivalents to the Molex 0901200774. All three maintain the critical 14-position, 2.54mm pitch configuration with through-hole solder termination and UL94 V-0 flammability rating.

Hirose A2-14PA-2.54DSA(71) is recommended for applications requiring the full -55°C to 125°C operating temperature range of the original part, as it supports -55°C to 85°C. For applications operating within -40°C to 105°C, both Harwin M20-9991445 and M20-9991446 are suitable. The M20-9991446 variant features tin mating contact finish instead of gold, which may be preferred in cost-sensitive applications where gold plating is not required.

All three primary substitutes carry Active product status and maintain RoHS3 compliance, ensuring long-term availability and regulatory alignment.

Secondary Reference (40-Position, Non-Equivalent):

The TE Connectivity 4-103185-0 is included in the substitute list but is not a direct equivalent due to its 40-position configuration. This part is listed for reference only and should not be selected as a replacement for 14-position applications. The part carries Obsolete product status, further limiting its suitability for new designs.

Frequently Asked Questions (FAQ)

Q: Can I use the Harwin M20-9991446 with tin mating contacts instead of the gold-plated Molex original?

A: Yes. Both tin and gold contact finishes are acceptable for 2.54mm pitch header connectors in standard board-to-board applications. The choice depends on application requirements. Gold plating provides superior corrosion resistance in high-humidity or harsh environments, while tin is suitable for controlled indoor environments and cost-sensitive applications.

Q: Does the Hirose A2-14PA-2.54DSA(71) support the full temperature range of the original Molex part?

A: The Hirose part supports -55°C to 85°C, which covers the lower end of the original -55°C to 125°C range. If your application requires operation above 85°C, the Hirose substitute is not suitable. The Harwin M20-9991445 and M20-9991446 support -40°C to 105°C, which covers most industrial applications but does not extend to the full 125°C upper limit.

Q: Are all substitute parts RoHS compliant?

A: The Hirose A2-14PA-2.54DSA(71), Harwin M20-9991445, and Harwin M20-9991446 are all RoHS compliant (RoHS Compliant or ROHS3 Compliant). The TE Connectivity 4-103185-0 carries "Not applicable" RoHS status due to its Obsolete product classification.

Q: What is the difference between the two Harwin variants, M20-9991445 and M20-9991446?

A: Both Harwin parts are identical except for contact finish. The M20-9991445 features gold mating contact finish, while the M20-9991446 features tin mating contact finish. Both support identical electrical and mechanical specifications, including 3A current rating per contact, -40°C to 105°C operating temperature, and cuttable connector type.

Q: Why is the TE Connectivity 4-103185-0 listed as a substitute if it has 40 positions instead of 14?

A: The TE Connectivity part is included in the manufacturer's substitute list but does not meet the core substitution criteria due to its 40-position configuration. It is provided for reference only and should not be used as a replacement for 14-position applications. The part's Obsolete status further limits its practical utility.

Q: Can I mix and match substitute parts in the same design?

A: Yes, provided all parts meet your application's electrical, mechanical, and environmental requirements. However, maintaining consistency within a single design is recommended to simplify procurement, inventory management, and field service procedures.
