Equivalent & Substitute Parts for Molex 0010892321

Part Overview

The Molex 0010892321 is a rectangular connector header designed for through-hole mounting applications. This connector features a 32-position, 2-row configuration with 0.100" (2.54mm) pitch spacing, suitable for board-to-board or cable interconnections. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement planning. Active substitute options are available from both Molex and third-party manufacturers that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0010892321 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 32
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Unshrouded
• Style: Board to Board or Cable

Acceptable Variation Parameters:

• Contact Finish - Mating: Gold (thickness may vary)
• Contact Material: Phosphor Bronze or Copper Alloy
• Insulation Material: Polyester Glass Filled, LCP Glass Filled, or PBT
• Contact Finish - Post: Tin or Gold
• Overall Contact Length: Minor dimensional variations within tolerance

Both substitute parts meet these criteria and are therefore electrically and mechanically compatible with the original Molex 0010892321.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with full ROHS3 compliance and UL94 V-0 flammability certification, meeting the regulatory requirements of the original Molex 0010892321.

Molex 0010897322 is the manufacturer-recommended substitute from Molex. It maintains the same connector family lineage (C-Grid series) and provides direct functional equivalence. The transition from Polyester to Liquid Crystal Polymer insulation material represents an improvement in thermal and mechanical performance characteristics. This option is preferred for applications requiring continuity within the Molex product ecosystem.

Samtec TSW-116-07-G-D provides an alternative from an independent manufacturer. The TSW series offers documented operating temperature specifications (-55°C ~ 125°C), which may be beneficial for applications requiring explicit thermal performance data. The PBT insulation material and phosphor bronze contact material are standard alternatives within the industry for this connector class. This option is suitable for applications where multi-source qualification is required or where Samtec components are already established in the supply chain.

Both substitutes maintain identical electrical and mechanical interface specifications, ensuring direct pin-for-pin compatibility with existing PCB designs and mating connectors.

Frequently Asked Questions (FAQ)

Q: Can Molex 0010897322 be used as a direct replacement for Molex 0010892321?

A: Yes. Both parts share identical pitch spacing (0.100"), position count (32), row configuration (2), and mounting methodology (through-hole solder). The primary difference is the insulation material upgrade from Polyester to Liquid Crystal Polymer, which does not affect electrical or mechanical compatibility.

Q: What is the difference between the Molex and Samtec substitute options?

A: Both are functionally equivalent. The Molex 0010897322 maintains the same manufacturer and series family. The Samtec TSW-116-07-G-D provides an alternative source with published operating temperature specifications. Selection depends on supply chain strategy and existing component qualification requirements.

Q: Are there dimensional differences between these parts?

A: Minor variations exist in contact length and insulation height. The Molex 0010892321 has an overall contact length of 0.437" (11.10mm) and insulation height of 0.090" (2.29mm). The Samtec TSW-116-07-G-D has an overall contact length of 0.430" (10.92mm) and insulation height of 0.100" (2.54mm). These variations are within standard connector tolerance ranges and do not affect mating compatibility.

Q: What is the significance of the contact finish thickness differences?

A: The original part specifies 30.0µin (0.76µm) gold plating on mating contacts. The substitutes specify 15.0µin (0.38µm) and 10.0µin (0.25µm) respectively. All values meet industry standards for gold-plated connector contacts and provide equivalent corrosion resistance and electrical performance for standard applications.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts carry ROHS3 Compliant certification and are suitable for applications subject to RoHS regulations.

Q: Which substitute should be selected for new designs?

A: For new designs, either substitute is acceptable based on supply chain and qualification requirements. The Molex 0010897322 is the manufacturer-recommended option. The Samtec TSW-116-07-G-D is suitable where multi-source qualification or published thermal specifications are required.
