Amphenol ICC 68685-432 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68685-432 is a 32-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications. This connector features through-hole solder termination, tin contact finish, and operates across -65°C to 125°C. The product is currently active and available in high inventory (709 pcs). Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, application-specific requirements, or design optimization needs.

Substitute Part Grouping Explanation

Substitution eligibility for the 68685-432 is determined by the following critical parameters:

Connector Type & Contact Configuration: Must be receptacle with female socket contacts
Position Count & Pitch: Must maintain 32 positions at 0.100" (2.54mm) mating pitch
Mounting & Termination: Must support through-hole solder termination
Mechanical Compatibility: Single-row configuration with 0.276" (7.00mm) insulation height
Electrical Performance: Push-pull fastening type and UL94 V-0 flammability rating
Environmental Range: Operating temperature compatibility within -65°C to 125°C

The substitute part TE Connectivity AMP Connectors 3-215297-2 meets these core substitution criteria. Variations in contact finish material (gold vs. tin), insulation material composition, and RoHS compliance status do not preclude functional equivalence when electrical and mechanical parameters align.

Engineering Selection Recommendations

Primary Part (68685-432): Select when tin contact finish is specified, PPS insulation material is required, or RoHS non-compliance is acceptable for the application. This part is active with robust inventory availability (709 pcs).

Substitute Part (3-215297-2): Select when gold contact finish is preferred for enhanced corrosion resistance, ROHS3 compliance is mandated, or polyester glass-filled insulation meets application requirements. This part maintains active status with higher inventory (998 pcs) and is manufacturer-recommended as an equivalent.

Both parts satisfy UL94 V-0 flammability requirements and maintain identical mechanical pitch, position count, and mounting configuration. Selection between them depends on specific compliance requirements and contact finish specifications for the end application.

Frequently Asked Questions (FAQ)

Q: Can the 3-215297-2 directly replace the 68685-432 in existing designs?

A: Yes, provided the application does not specifically require tin contact finish or PPS insulation material. The 3-215297-2 maintains identical pitch (0.100"), position count (32), mounting type (through-hole), and fastening mechanism (push-pull). Verify that gold contact finish and polyester glass-filled insulation are compatible with your circuit board and environmental conditions.

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

A: Tin contact finish (68685-432) provides cost-effective performance for general applications. Gold contact finish (3-215297-2) offers superior corrosion resistance and lower contact resistance, beneficial in high-reliability or corrosive environments. Both finishes are electrically functional at the specified 1000V rating.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS3 compliance (3-215297-2) versus non-compliance (68685-432) reflects material composition restrictions but does not alter electrical or mechanical performance. Selection depends on regulatory requirements for your end product.

Q: Are the insulation materials interchangeable?

A: Both PPS (68685-432) and polyester glass-filled (3-215297-2) materials meet UL94 V-0 flammability standards and support the -65°C to 125°C operating range. Material selection depends on specific chemical resistance, mechanical strength, or thermal requirements of your application.

Q: What is the significance of kinked pin termination in the substitute part?

A: Kinked pin termination in the 3-215297-2 provides enhanced mechanical retention during solder reflow, improving board-level reliability. This does not affect electrical compatibility with standard through-hole solder processes.
