Key Parameters

Substitute Part Grouping Explanation

The Molex 0428193233 qualifies as a direct substitute for the 0428193232 based on the following critical parameters that determine functional interchangeability:

• Identical manufacturer (Molex)
• Identical series (Mini-Fit Sr 42819)
• Identical connector type (Header)
• Identical contact type (Male Blade)
• Identical number of positions (3)
• Identical number of rows (1)
• Identical pitch - mating (0.394" / 10.00mm)
• Identical mounting type (Through Hole)
• Identical termination method (Solder)
• Identical shrouding configuration (Shrouded - 4 Wall)
• Identical fastening type (Locking Ramp)
• Identical insulation material (Polyamide PA46, Nylon 4/6, Glass Filled)
• Identical contact material (Copper Zirconium Alloy)
• Identical insulation height (0.827" / 21.00mm)
• Identical contact post length (0.201" / 5.11mm)
• Identical base product number (042819)

The primary difference between these parts is the contact finish on the mating surface and product status, with the substitute offering improved availability and active design status.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0428193233 is the appropriate selection for new designs and ongoing production applications. This part maintains identical mechanical and electrical specifications to the 0428193232 while offering active product status and superior inventory availability. The 0428193233 carries ROHS3 compliance and UL94 V-0 flammability certification, meeting the same regulatory requirements as the original part.

The contact finish difference (gold mating surface on the substitute versus tin on the original) does not affect functional compatibility in standard board-to-cable/wire applications. Both parts utilize identical insulation materials, mounting configurations, and fastening mechanisms, ensuring direct mechanical and electrical interchangeability.

For applications requiring the original tin-finished mating surface specification, the 0428193232 remains available in inventory. However, the substitute part is recommended for all new designs and production continuity due to its active status and higher stock levels.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0428193233 directly replace the 0428193232 in existing assemblies?

A: Yes. The 0428193233 is mechanically and electrically identical to the 0428193232. Both parts share the same 3-position configuration, 0.394" (10.00mm) pitch, through-hole mounting, shrouded 4-wall design, and locking ramp fastening. The parts are fully interchangeable in board-to-cable/wire applications.

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

A: The primary differences are product status and contact finish on the mating surface. The 0428193232 is classified as "Not For New Designs" with tin-finished mating contacts, while the 0428193233 is an active product with gold-finished mating contacts. Both parts meet ROHS3 compliance and UL94 V-0 flammability requirements.

Q: Are there any compatibility concerns with the different contact finishes?

A: No. Both tin and gold contact finishes are standard for this connector series and do not affect functional compatibility. The contact finish difference does not impact electrical performance or mechanical mating in standard applications.

Q: What is the inventory status for these parts?

A: The 0428193232 has 844 pieces in stock, while the 0428193233 has 1278 pieces in stock. Both are available as new original components.

Q: Which part should be specified for new product designs?

A: The Molex 0428193233 should be specified for new designs. This part carries active product status, ensuring long-term availability and support. The 0428193232 is designated "Not For New Designs" and should be reserved for legacy system maintenance only.

Q: Are both parts RoHS compliant?

A: Yes. Both the 0428193232 and 0428193233 are ROHS3 compliant and carry UL94 V-0 flammability certification. Moisture sensitivity level is 1 (Unlimited) for both parts.
