Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68683-423LF is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 46 positions at 0.100" (2.54mm) mating pitch
• Row Configuration: 2 rows with 0.100" (2.54mm) row spacing
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Board-to-Board Style: Vertical or right-angle orientation for PCB interconnection
• Compliance & Environmental: UL94 V-0 flammability rating and operating temperature compatibility

The substitute part 803-43-046-10-001000 (Mill-Max Manufacturing Corp., Series 803) meets these core mechanical and electrical requirements, enabling direct functional replacement in applications where the specified parameters are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both the 68683-423LF and 803-43-046-10-001000 are active production parts with UL94 V-0 flammability certification and full RoHS compliance status. The primary distinction lies in contact finish specification: the Amphenol ICC part features tin plating with 1000V voltage rating, while the Mill-Max substitute provides gold-plated contacts with 4.5A current rating specification and operates across a slightly narrower temperature range (-55°C to 125°C versus -65°C to 125°C).

Selection between these parts depends on application-specific requirements: tin-plated contacts are suitable for general-purpose and industrial applications with standard voltage isolation needs, whereas gold-plated contacts offer enhanced corrosion resistance and contact reliability in demanding environments. Both parts maintain identical mechanical footprint, pitch, row configuration, and board-to-board mounting characteristics, ensuring PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 803-43-046-10-001000 directly replace the 68683-423LF in existing designs?

A: Yes, provided the application does not require the full -65°C lower temperature limit or the 1000V voltage rating of the original part. The substitute maintains identical mechanical dimensions, pitch, row spacing, and through-hole solder termination, ensuring PCB compatibility without layout modification.

Q: What is the significance of the contact finish difference between tin and gold plating?

A: Tin plating provides cost-effective corrosion protection suitable for standard industrial and automotive applications. Gold plating offers superior contact resistance stability and corrosion immunity, beneficial in high-reliability or harsh-environment applications. Both finishes are compatible with standard PCB assembly processes.

Q: Are there packaging or inventory considerations when selecting between these parts?

A: Both parts are supplied in tube packaging and are active production items. The 68683-423LF has 776 pieces in stock, while the 803-43-046-10-001000 has 995 pieces available. Packaging format is identical, requiring no assembly process modification.

Q: Does the contact material difference (Phosphor Bronze vs. Beryllium Copper) affect compatibility?

A: Contact material differences do not affect mechanical or electrical compatibility with mating connectors. Both materials provide adequate conductivity and mechanical durability for 0.100" pitch board-to-board applications. Material selection reflects manufacturer design choices and does not impact interchangeability.

Q: What compliance certifications apply to both parts?

A: Both parts are UL94 V-0 rated for flammability and RoHS compliant. The 68683-423LF is REACH Affected, while the 803-43-046-10-001000 is REACH Unaffected. Both carry EAR99 ECCN classification and 8536.69.4040 HTSUS code.
