Amphenol ICC 68683-409LF Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68683-409LF is an 18-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications in automotive, industrial, telecommunications, and general-purpose environments. This connector features tin-plated contacts, through-hole solder termination, and push-pull fastening. The part is currently active in production with 824 units in stock.

Equivalent and substitute parts are identified based on matching core electrical and mechanical parameters: 18-position configuration, 0.100" pitch, 2-row layout, through-hole mounting, push-pull fastening, and UL94 V-0 flammability rating. Substitutes may vary in contact finish material, insulation composition, and current rating specifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following core parameters:

Connector Configuration: 18 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
Mounting & Termination: Through-hole solder termination with push-pull fastening
Electrical Safety: UL94 V-0 flammability rating and MSL 1 classification
Environmental Compliance: RoHS and REACH status alignment

The four identified substitute parts meet these core criteria. Variations exist in contact finish material (tin versus gold plating), contact geometry (square versus circular), insulation material composition, and current rating specifications. These variations do not prevent functional substitution in applications where the main part is specified, provided that the mating connector and circuit design accommodate the physical and electrical differences.

Engineering Selection Recommendations

All four substitute parts maintain active product status and meet UL94 V-0 flammability requirements. Selection between the main part and substitutes depends on application-specific requirements:

TE Connectivity 215307-9 (AMPMODU HV-100): Gold-plated contacts with kinked pin termination option. Insulation height matches the main part at 0.276". Suitable for applications requiring enhanced contact reliability through gold plating. ROHS3 compliant with MSL 1 rating.

TE Connectivity 5-534206-9 (AMPMODU Mod II): Gold-plated contacts with specified 2A current rating. Insulation height is 0.320", which is 0.044" taller than the main part. Operating temperature range matches the main part (-65°C ~ 125°C). ROHS3 compliant with REACH Unaffected status.

Mill-Max 803-41-018-10-001000: Gold-plated contacts with circular contact geometry and beryllium copper material. Rated for 4.5A current. Operating temperature range is -55°C ~ 125°C (5°C higher minimum than main part). ROHS3 compliant with Not Applicable MSL classification.

Mill-Max 803-93-018-10-001000: Gold-plated contacts with tin-lead post finish and circular contact geometry. Rated for 4.5A current. Operating temperature range is -55°C ~ 125°C. ROHS3 compliant with Not Applicable MSL classification.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 68683-409LF with any of these parts directly?

A: Direct substitution requires verification that the mating connector and PCB layout accommodate the physical differences. The main part features square tin-plated contacts, while all substitutes feature gold-plated contacts with either square or circular geometry. Insulation height varies between 0.276" and 0.320", which may affect board spacing. Consult your mating connector specification and PCB design before substitution.

Q: What is the difference between tin and gold contact finishes?

A: Tin-plated contacts (main part) provide cost-effective performance for general applications. Gold-plated contacts (all substitutes) offer enhanced corrosion resistance and improved contact reliability, particularly in environments with moisture or corrosive atmospheres. Gold plating is typically specified for high-reliability or long-term storage applications.

Q: Do the Mill-Max parts have different contact geometry?

A: Yes. The main part and TE Connectivity substitutes feature square contacts. The Mill-Max 803 series parts (803-41-018-10-001000 and 803-93-018-10-001000) feature circular contacts with beryllium copper material. This geometric difference may affect mating force and contact pressure characteristics. Verify compatibility with your mating connector design.

Q: What is the significance of the operating temperature range difference?

A: The main part operates from -65°C to 125°C. The Mill-Max substitutes operate from -55°C to 125°C, providing a 10°C higher minimum temperature limit. For applications requiring operation below -55°C, the main part or TE Connectivity substitutes are required.

Q: Are all parts RoHS compliant?

A: Yes. The main part is RoHS Compliant. All four substitutes are ROHS3 Compliant, which represents the current RoHS directive standard. All parts meet REACH requirements or are REACH Unaffected, with the exception of TE Connectivity 215307-9, which has Vendor Undefined REACH status.

Q: What packaging options are available?

A: The main part is supplied in Tube packaging. TE Connectivity 215307-9 is supplied in Tray packaging. TE Connectivity 5-534206-9 and both Mill-Max parts are supplied in Tube packaging. Packaging selection may affect procurement logistics and handling procedures.

Q: Which substitute offers the highest current rating?

A: The Mill-Max 803-41-018-10-001000 and 803-93-018-10-001000 both offer 4.5A current rating, compared to 2A for the TE Connectivity 5-534206-9. The main part and TE Connectivity 215307-9 do not specify current ratings. For high-current applications, the Mill-Max parts are recommended.
