Substitute Part Grouping Explanation

The Mill-Max Manufacturing Corp. 803-43-006-10-001000 is identified as a manufacturer-recommended substitute for the Amphenol ICC 68683-403LF. Substitution eligibility is determined by the following critical parameters that must align between the main part and substitute:

• Connector Type & Contact Type: Both are receptacles with female sockets
• Position Count & Pitch: Both feature 6 positions at 0.100" (2.54mm) mating pitch
• Row Configuration: Both use 2-row layout with 0.100" (2.54mm) row spacing
• Mounting & Termination: Both are through-hole mounted with solder termination
• Fastening Mechanism: Both use push-pull fastening
• Board-to-Board Style: Both are configured for board-to-board interconnection
• Insulation Height: Both maintain 0.276" (7.00mm) insulation height
• Flammability Rating: Both meet UL94 V-0 material flammability requirements
• Compliance: Both are RoHS compliant and carry EAR99 ECCN classification

Variations in contact finish (tin versus gold), contact material composition, and operating temperature range do not preclude substitution when the above core parameters are matched.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol ICC 68683-403LF and Mill-Max Manufacturing Corp. 803-43-006-10-001000 are active production parts with full RoHS compliance. The primary distinction between these parts lies in contact finish specification and operating temperature range.

The 68683-403LF features tin-plated mating contacts and supports an extended lower operating temperature of -65°C, making it suitable for applications requiring broader thermal range coverage. The 803-43-006-10-001000 provides gold-plated mating contacts with a rated current specification of 4.5A and operates from -55°C to 125°C.

Selection between these parts should be based on specific application requirements: choose the 68683-403LF when extended low-temperature operation or tin-plated contact specifications are required; select the 803-43-006-10-001000 when gold-plated contact durability or explicit current rating documentation is needed. Both parts meet UL94 V-0 flammability requirements and are suitable for automotive, industrial, and telecommunications applications.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 803-43-006-10-001000 directly replace the Amphenol ICC 68683-403LF in existing designs?

A: Yes, from a mechanical and electrical standpoint. Both connectors share identical pitch (0.100"), position count (6), row configuration (2 rows), mounting type (through-hole), and fastening mechanism (push-pull). The primary differences are contact finish (gold versus tin) and operating temperature range (-55°C to 125°C versus -65°C to 125°C). Verify that your application does not require the extended low-temperature capability or specific tin-plated contact requirements of the original part.

Q: What is the significance of the contact finish difference between these parts?

A: The 68683-403LF uses tin-plated mating contacts, while the 803-43-006-10-001000 uses gold-plated mating contacts. Gold plating provides enhanced corrosion resistance and contact reliability in high-humidity or corrosive environments. Tin plating is suitable for general-purpose applications. Contact finish selection should align with your application's environmental exposure and reliability requirements.

Q: Are there any dimensional incompatibilities between these connectors?

A: Both connectors maintain the same insulation height (0.276"), pitch spacing (0.100"), and row spacing (0.100"). The contact post length differs slightly: 0.115" (2.92mm) for the 68683-403LF versus 0.118" (3.00mm) for the 803-43-006-10-001000. This minor variation is within typical PCB through-hole tolerance and does not create compatibility issues.

Q: Do both parts meet the same compliance and certification standards?

A: Both parts are RoHS compliant and carry UL94 V-0 material flammability ratings. The 68683-403LF is RoHS Compliant, while the 803-43-006-10-001000 is ROHS3 Compliant. Both carry EAR99 ECCN classification and share the same HTSUS code (8536.69.4040). Both are classified as Moisture Sensitivity Level 1 or Not Applicable, indicating no special moisture handling requirements.

Q: What is the operating temperature consideration when substituting these parts?

A: The 68683-403LF operates from -65°C to 125°C, while the 803-43-006-10-001000 operates from -55°C to 125°C. If your application requires operation below -55°C, the 68683-403LF is the appropriate choice. For applications within the -55°C to 125°C range, both parts are functionally equivalent from a thermal standpoint.

Q: Are packaging and inventory considerations relevant to substitution?

A: Both parts are supplied in tube packaging. Current inventory shows 1007 units of the 68683-403LF and 1108 units of the 803-43-006-10-001000 in stock. Substitution may be driven by inventory availability or supply chain requirements. Verify lead times and availability with your component supplier for your specific procurement timeline.
