Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 68683-236 are qualified based on the following critical parameters that must match or exceed the original specification:

Mandatory Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 72
• Pitch - Mating: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Insulation Color: Black
• Material Flammability Rating: UL94 V-0

The identified substitutes (Mill-Max 803-43-072-10-001000 and 803-93-072-10-001000) meet all mandatory parameters. Variations in contact material, contact finish thickness, and post finish are acceptable within the scope of board-to-board rectangular connector applications.

Parameter Comparison

Engineering Selection Recommendations

68683-236 (Amphenol ICC - Dubox™ Series): Select this part for applications requiring the original specification. The part is active in production with adequate inventory (818 units). RoHS non-compliant status applies to legacy or non-regulated applications. Operating temperature range extends to -65°C, suitable for extended low-temperature environments.

803-43-072-10-001000 (Mill-Max - Series 803): This substitute meets all mandatory electrical and mechanical parameters. ROHS3 compliance is available for regulated applications. Beryllium copper contact material and increased contact finish thickness provide enhanced durability. Operating temperature minimum is -55°C. Tin post finish is compatible with standard solder processes. Current rating of 4.5A is specified.

803-93-072-10-001000 (Mill-Max - Series 803): This substitute is functionally equivalent to 803-43-072-10-001000 with the exception of post finish (Tin-Lead instead of Tin). ROHS3 compliance applies. Suitable for applications where Tin-Lead termination is acceptable. Inventory availability is higher (1172 units).

Frequently Asked Questions (FAQ)

Q: Can 68683-236 be directly replaced with Mill-Max 803-43-072-10-001000 or 803-93-072-10-001000?

A: Yes. Both Mill-Max parts meet the critical substitution parameters: 72 positions, 0.100" pitch, 2-row configuration, through-hole solder termination, push-pull fastening, and gold-plated mating contacts. Physical and electrical compatibility is maintained for board-to-board applications.

Q: What is the difference between 803-43-072-10-001000 and 803-93-072-10-001000?

A: The primary difference is the contact post finish. The 803-43 uses Tin finish, while the 803-93 uses Tin-Lead finish. Both parts are otherwise identical in electrical and mechanical specifications. Selection depends on process requirements and regulatory compliance needs.

Q: Does the operating temperature range difference affect substitution?

A: The 68683-236 operates from -65°C to 125°C, while Mill-Max substitutes operate from -55°C to 125°C. For applications requiring operation below -55°C, the original 68683-236 is required. For standard industrial and commercial temperature ranges, the substitutes are suitable.

Q: Are there RoHS compliance implications when substituting?

A: The original 68683-236 is RoHS non-compliant. Both Mill-Max substitutes are ROHS3 compliant. If your application or market requires RoHS compliance, the Mill-Max parts provide this advantage. If legacy non-compliant parts are acceptable, either option is viable.

Q: How do contact material differences affect performance?

A: The 68683-236 uses Phosphor Bronze contacts, while Mill-Max substitutes use Beryllium Copper. Beryllium Copper provides superior spring characteristics and contact durability. Both materials are suitable for 0.100" pitch board-to-board connectors. Contact finish thickness is also increased in Mill-Max parts (30.0µin vs. 15.0µin for mating surface), enhancing wear resistance.

Q: Is the 0.003" difference in contact post length significant?

A: The 68683-236 has a post length of 0.115" (2.92mm) compared to 0.118" (3.00mm) for Mill-Max substitutes. This 0.003" difference is within typical PCB tolerance ranges and does not affect mechanical or electrical compatibility for standard through-hole solder applications.

Q: What current rating should be used for the 68683-236?

A: The 68683-236 does not specify a current rating in the provided data. Mill-Max substitutes are rated at 4.5A per contact. For applications requiring current rating verification, consult the original manufacturer's detailed specifications or contact technical support.
