68683-323LF Equivalent & Substitute Parts

Part Overview

The 68683-323LF is a 46-position rectangular receptacle connector manufactured by Amphenol ICC (FCI) from the Dubox™ series. This board-to-board connector features 0.100" (2.54mm) pitch, through-hole solder termination, and gold-plated mating contacts. The component is actively produced and widely used in automotive, industrial, telecommunications, and general-purpose applications. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component sourcing flexibility and inventory optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68683-323LF is determined by strict alignment of the following critical parameters:

• Connector type: Receptacle with female socket contacts
• Position count: 46 positions
• Pitch specification: 0.100" (2.54mm) mating pitch with 0.100" (2.54mm) row spacing
• Mounting configuration: Through-hole solder termination
• Fastening mechanism: Push-pull engagement
• Contact finish: Gold-plated mating surface
• Insulation material and color: Black insulation
• Flammability compliance: UL94 V-0 rating
• Environmental compliance: RoHS status

The identified substitute part 803-43-046-10-001000 (Mill-Max Manufacturing Corp.) meets these core substitution criteria. Variations in secondary parameters such as contact material composition, contact finish thickness on post surfaces, and specific operating temperature ranges do not preclude substitution when primary mechanical and electrical interfaces remain compatible.

Parameter Comparison

Engineering Selection Recommendations

Both the 68683-323LF and 803-43-046-10-001000 are active production components with current inventory availability. The Amphenol ICC part carries RoHS Compliant certification, while the Mill-Max substitute carries ROHS3 Compliant certification, both meeting current regulatory requirements. The operating temperature range of the Mill-Max part (-55°C ~ 125°C) is narrower than the Amphenol ICC part (-65°C ~ 125°C) at the lower temperature extreme. Selection between these parts should be based on application-specific temperature requirements and supply chain considerations. Both components satisfy UL94 V-0 flammability requirements and maintain identical mechanical interface specifications for board-to-board connectivity.

Frequently Asked Questions (FAQ)

Q: Can the 803-43-046-10-001000 be used as a direct replacement for the 68683-323LF?

A: Yes, the 803-43-046-10-001000 qualifies as a substitute based on matching connector type, position count, pitch, row spacing, mounting method, termination type, fastening mechanism, contact finish, insulation properties, and flammability rating. The primary consideration is the lower minimum operating temperature of -55°C versus -65°C for the original part.

Q: What are the key mechanical interface parameters that must match for substitution?

A: Critical matching parameters include 46-position count, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing, through-hole mounting, solder termination, push-pull fastening, and 0.276" (7.00mm) insulation height. These parameters ensure physical and electrical compatibility with mating connectors and PCB layouts.

Q: Are there differences in contact material between these parts?

A: Yes. The 68683-323LF uses phosphor bronze contacts, while the 803-43-046-10-001000 uses beryllium copper contacts. Both materials are suitable for the specified applications and maintain the required electrical performance with gold-plated mating surfaces.

Q: What is the significance of the RoHS compliance difference?

A: The Amphenol ICC part is RoHS Compliant, while the Mill-Max part is ROHS3 Compliant. Both certifications meet current regulatory requirements for hazardous substance restrictions. ROHS3 represents an updated compliance standard and does not indicate incompatibility.

Q: How do the contact finish thicknesses differ?

A: The mating contact gold finish is identical at 30.0µin (0.76µm) for both parts. The post contact finish differs: the Amphenol ICC part has 100.0µin (2.54µm) tin finish, while the Mill-Max part has 200.0µin (5.08µm) tin finish. These variations do not affect substitution compatibility.

Q: What inventory considerations apply to these parts?

A: The Amphenol ICC 68683-323LF has 702 pieces in stock, while the Mill-Max 803-43-046-10-001000 has 995 pieces in stock. Both are actively produced and available for immediate procurement.
