Amphenol ICC 68683-302 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68683-302 is a 4-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications. This connector features gold-plated mating contacts, through-hole solder termination, and push-pull fastening. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where similar functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 68683-302 is determined by the following critical parameters:

• Connector type (Receptacle) and contact type (Female Socket)
• Pitch and row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole) and termination (Solder)
• Fastening mechanism (Push-Pull)
• Contact finish (Gold mating surface)
• Operating temperature range (-65°C ~ 125°C)
• Material flammability rating (UL94 V-0)

The substitute parts listed below maintain compatibility with these core parameters. However, variations exist in position count, insulation material, and compliance certifications, which must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 215307-4 (AMPMODU HV-100 Series)

This 8-position connector maintains the core mechanical and electrical compatibility with the 68683-302. It shares identical pitch (0.100"), row spacing, mounting type, and fastening mechanism. The connector is active and ROHS3 compliant, providing regulatory advantage for new designs. The primary consideration is the increased position count (8 vs. 4), which requires PCB layout accommodation. The insulation material differs (Polyester vs. PPS), and operating temperature is not specified in available data.

TE Connectivity 535598-2 (AMPMODU Mod IV Series)

This 2-position connector provides a lower-density alternative with identical row spacing and mounting characteristics. It maintains push-pull fastening and gold mating contact finish. Operating temperature range matches the original part (-65°C ~ 125°C). The connector is active but RoHS non-compliant. The reduced position count and unspecified mating pitch require verification for specific applications. Current rating is specified at 2A.

Frequently Asked Questions (FAQ)

Q: Can the 215307-4 directly replace the 68683-302 in existing designs?

A: Direct replacement is not recommended without PCB layout modification. The 215307-4 provides 8 positions versus the 4 positions of the 68683-302. The mechanical footprint and contact spacing are compatible, but the increased position count requires additional PCB routing and connector mounting space.

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

A: The 68683-302 uses Polyphenylene Sulfide (PPS) glass-filled insulation, while both substitute parts use Polyester glass-filled insulation. PPS offers superior thermal and chemical resistance, which may be critical in specific industrial or automotive applications.

Q: Is the 535598-2 suitable for high-voltage applications?

A: The voltage rating for the 535598-2 is not specified in available technical data. The original 68683-302 is rated for 1000V. Voltage compatibility must be verified through the manufacturer before selection for high-voltage applications.

Q: What is the impact of the different contact finish thicknesses?

A: The 68683-302 specifies 30.0µin (0.76µm) gold mating contact finish. The 215307-4 provides 31.5µin (0.80µm), and the 535598-2 provides 10.0µin (0.25µm). Thicker gold plating generally provides enhanced durability and corrosion resistance, particularly in harsh environmental conditions.

Q: Are there RoHS compliance considerations for substitute selection?

A: The 68683-302 is RoHS non-compliant. The 215307-4 is ROHS3 compliant, making it suitable for applications requiring regulatory compliance. The 535598-2 remains RoHS non-compliant. New designs should prioritize the 215307-4 where regulatory requirements apply.

Q: What is the significance of the kinked pin termination option in the 215307-4?

A: The 215307-4 offers both kinked pin and solder termination options. Kinked pins provide mechanical retention during PCB assembly, while solder termination offers permanent connection. Selection depends on assembly process requirements and mechanical stress considerations.
