Amphenol ICC 68683-408LF Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68683-408LF is a 16-position receptacle connector with 0.100" (2.54mm) pitch, designed for through-hole board-to-board applications. This connector features tin contact finish, push-pull fastening, and operates across -65°C to 125°C. The part is active in production and RoHS compliant, making it suitable for automotive, industrial, telecommunications, and general-purpose applications.

Substitute parts are necessary when the original manufacturer part becomes unavailable, when alternative contact finishes (such as gold plating) are required for enhanced corrosion resistance, or when specific insulation materials or contact geometries better suit application requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the 68683-408LF is determined by the following critical parameters:

Connector geometry: 16 positions, 0.100" (2.54mm) pitch, 2-row configuration, 0.100" row spacing
Mounting interface: Through-hole termination with push-pull fastening
Electrical performance: Board-to-board connectivity with female socket contacts
Environmental compliance: UL94 V-0 flammability rating and RoHS compliance
Operating conditions: -55°C to 125°C minimum temperature range (note: main part specifies -65°C minimum)

All substitute parts listed maintain these core geometric and functional parameters. Variations exist in contact finish (tin versus gold), contact material (phosphor bronze versus beryllium copper), insulation material composition, and specific contact dimensions. These variations do not affect mechanical interchangeability or basic electrical function within the specified voltage and current parameters.

Engineering Selection Recommendations

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

TE Connectivity 215307-8 and 5-534206-8: Both are ROHS3 compliant alternatives with gold contact finish. The 215307-8 offers tray packaging with kinked pin termination, while 5-534206-8 provides tube packaging with standard solder termination and rated current of 2A per contact. The 5-534206-8 maintains the same operating temperature range as the main part (-65°C ~ 125°C).

Mill-Max 803-43-016-10-001000 and 803-93-016-10-001000: Both are ROHS3 compliant with beryllium copper contacts rated at 4.5A per contact. The 803-43 features tin post finish, while 803-93 uses tin-lead post finish. Both operate at -55°C to 125°C and feature circular contact geometry with PCT/polyester insulation.

Samtec Tiger Claw™ BCS Series (BCS-108-F-D-TE, BCS-108-L-D-DE-BE, BCS-108-L-D-TE-002): All three are ROHS3 compliant with 4.6A per contact rating and 475VAC voltage rating. The BCS-108-F-D-TE is standard board-to-board entry. The BCS-108-L-D-DE-BE supports bottom or top entry configuration. The BCS-108-L-D-TE-002 is loaded with 15 positions instead of 16. All feature liquid crystal polymer insulation and phosphor bronze contacts with gold finish.

Frequently Asked Questions (FAQ)

Q: Can the 68683-408LF be directly replaced with any of these substitute parts?

A: Yes, all listed parts are mechanically and electrically interchangeable for board-to-board through-hole applications with 16 positions at 0.100" (2.54mm) pitch and push-pull fastening. Physical mounting footprints are identical. Verify insulation height compatibility with your PCB layout, as some substitutes have slightly different heights (0.276" to 0.320").

Q: What is the primary difference between the main part and the substitutes?

A: The main part features tin contact finish, while all substitutes use gold plating. Gold finish provides superior corrosion resistance and is preferred in high-reliability applications. Contact material also varies: the main part and most substitutes use phosphor bronze, while Mill-Max options use beryllium copper for higher current capacity (4.5A versus unspecified for the main part).

Q: Are there temperature range differences I should consider?

A: The main part operates at -65°C to 125°C. Most substitutes operate at -55°C to 125°C, a 10°C difference at the lower end. If your application requires operation below -55°C, only the TE Connectivity 5-534206-8 matches the full -65°C specification.

Q: What packaging options are available?

A: The main part comes in tube packaging. Substitutes are available in tube (most Samtec and Mill-Max parts, TE 5-534206-8) or tray (TE 215307-8) packaging. Tube packaging is standard for through-hole components.

Q: Do all substitutes meet RoHS compliance?

A: Yes. The main part is RoHS compliant. All substitutes are either RoHS or ROHS3 compliant, meeting current environmental regulations.

Q: Which substitute offers the highest current rating?

A: The Mill-Max 803-43-016-10-001000 and 803-93-016-10-001000 both support 4.5A per contact. The Samtec BCS series supports 4.6A per contact. The TE 5-534206-8 supports 2A per contact. The main part does not specify a current rating.

Q: Can I use the BCS-108-L-D-TE-002 as a direct replacement?

A: The BCS-108-L-D-TE-002 is loaded with only 15 positions instead of 16. It is not a direct replacement for applications requiring all 16 positions to be populated.
