Substitute Part Grouping Explanation

Substitution for the 68683-340 is determined by the following critical parameters that must remain consistent:

Connector configuration: 80 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
Mounting and termination: Through-hole solder termination with push-pull fastening
Insulation specifications: Black color, UL94 V-0 flammability rating
Contact type: Female socket, board-to-board style

The primary substitute is the Amphenol ICC 68683-340LF, which maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. Mill-Max Manufacturing Corp. 803 series connectors provide functional equivalence with variations in contact material (beryllium copper vs. phosphor bronze), contact finish specifications, and insulation material composition. These variations are within acceptable substitution parameters for the stated application categories.

Engineering Selection Recommendations

Primary Direct Substitute: The Amphenol ICC 68683-340LF is the recommended direct replacement. It maintains identical electrical and mechanical specifications to the original 68683-340 while offering active product status and RoHS compliance. This part is functionally equivalent with no design modifications required.

Secondary Substitutes - Mill-Max 803 Series: The Mill-Max 803 series connectors provide functional equivalence for board-to-board 80-position 0.100" pitch applications. Selection within this series depends on specific compliance and contact finish requirements:

803-41-080-10-001000 and 803-41-080-10-004000: Gold-plated mating contacts with tin-plated posts. Suitable for applications requiring gold contact finish. Operating temperature range -55°C to 125°C.
803-43-080-10-001000: Gold-plated mating contacts with tin-plated posts, 4.5A current rating. Highest inventory availability (1095 pcs). Operating temperature range -55°C to 125°C.
803-91-080-10-001000: Gold-plated mating contacts with tin-lead plated posts. Suitable for legacy applications where tin-lead finish is specified. Operating temperature range -55°C to 125°C.
803-93-080-10-001000: Gold-plated mating contacts with tin-lead plated posts, packaged in tube format. Operating temperature range -55°C to 125°C.
803-99-080-10-001000 and 803-99-080-10-004000: Tin-lead plated mating and post contacts. Suitable for applications where tin-lead finish is required throughout. Operating temperature range -55°C to 125°C.

All Mill-Max substitutes carry ROHS3 compliance and active product status. The primary design difference is contact material composition (beryllium copper vs. phosphor bronze) and insulation material (PCT polyester vs. PPS glass-filled), which do not affect mechanical or electrical compatibility for the stated applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 68683-340LF be used as a direct replacement for the 68683-340?

A: Yes. The 68683-340LF maintains identical connector configuration, pitch, row spacing, mounting type, and termination method. The primary difference is product status (active vs. obsolete) and RoHS compliance. No design modifications are required.

Q: What is the key difference between Amphenol ICC and Mill-Max 803 series substitutes?

A: Both maintain the same 80-position, 0.100" pitch, board-to-board configuration. The primary differences are contact material (phosphor bronze in Amphenol vs. beryllium copper in Mill-Max), insulation material composition, and contact finish specifications. Operating temperature range for Mill-Max parts is -55°C to 125°C versus -65°C to 125°C for the original.

Q: Which Mill-Max part should I select if I need gold-plated contacts?

A: Parts 803-41-080-10-001000, 803-41-080-10-004000, 803-43-080-10-001000, 803-91-080-10-001000, and 803-93-080-10-001000 all feature gold-plated mating contacts. The 803-43-080-10-001000 offers the highest inventory availability and 30.0µin gold plating thickness matching the original specification.

Q: Are there packaging differences between substitutes?

A: Yes. The 68683-340LF and 803-93-080-10-001000 are packaged in tubes, while other Mill-Max parts are supplied in bulk. Packaging selection depends on production volume and handling requirements.

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

A: Contact finish thickness affects durability and wear resistance. The original 68683-340 specifies 30.0µin gold plating on mating contacts. Mill-Max parts 803-41-080-10-001000 and 803-91-080-10-001000 offer 10.0µin thickness, while 803-43-080-10-001000 and 803-93-080-10-001000 match the 30.0µin specification. Parts 803-99-080-10-001000 and 803-99-080-10-004000 specify 100.0µin tin-lead plating.

Q: Can I use a Mill-Max substitute in an application originally designed for the Amphenol ICC 68683-340?

A: Yes, provided the application does not require the lower operating temperature limit of -65°C. Mill-Max 803 series parts operate from -55°C to 125°C. All other mechanical and electrical parameters are compatible for board-to-board connector applications.
