Amphenol ICC 63440-001 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 63440-001 is a 32-position receptacle connector from the Minitek® series, designed for board-to-board applications with 0.079" (2.00mm) pitch through-hole mounting. This connector features gold-plated mating contacts and tin-lead plated posts, with latch lock fastening and UL94 V-0 flammability rating.

The 63440-001 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for legacy systems utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 63440-001 is determined by the following critical parameters:

• Connector Type & Contact Type: Must be receptacle with female socket contacts
• Position Count & Loading: Must accommodate 32 positions with 28 positions loaded
• Pitch & Row Spacing: Must maintain 0.079" (2.00mm) mating pitch and row spacing for mechanical and electrical compatibility
• Mounting & Termination: Must support through-hole solder termination
• Contact Finish - Mating: Must feature gold plating for reliable signal transmission
• Fastening Type: Must utilize latch lock mechanism
• Insulation Material & Flammability: Must meet UL94 V-0 rating

Based on these criteria, the following parts are identified as substitutes:

Direct Substitute (Same Series):

• 63440-001LF: Identical electrical and mechanical specifications; differs only in post contact finish (tin vs. tin-lead) and product status (active vs. obsolete)

Limited Compatibility Substitute (Different Series):

• 71609-309LF: Different connector series (Dubox™), position count (18 vs. 32), pitch (0.100" vs. 0.079"), and mounting type (surface mount right-angle vs. through-hole). Not a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Recommended):

The 63440-001LF is the primary substitute for the obsolete 63440-001. Both connectors share identical mechanical and electrical specifications within the Minitek® series. The 63440-001LF is currently in active production status with 1100 units in stock, ensuring supply chain continuity. The only material difference is the post contact finish (tin vs. tin-lead); both finishes are compatible with standard PCB solder processes. The 63440-001LF carries RoHS compliance certification, whereas the original part does not specify this status. Both parts maintain UL94 V-0 flammability rating and unlimited moisture sensitivity level (MSL 1).

For Alternative Applications (Limited Scope):

The 71609-309LF from the Dubox™ series is not a functional equivalent due to significant differences in position count (18 vs. 32), mating pitch (0.100" vs. 0.079"), mounting type (surface mount right-angle vs. through-hole), and fastening mechanism (push-pull vs. latch lock). This part is suitable only for applications where the design can accommodate these dimensional and mechanical changes. The 71609-309LF is active in production with 1538 units in stock and carries RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can the 63440-001LF directly replace the 63440-001 in existing designs?

A: Yes. The 63440-001LF is mechanically and electrically identical to the 63440-001. Both connectors maintain the same 32-position, 0.079" (2.00mm) pitch configuration, through-hole mounting, latch lock fastening, and gold-plated mating contacts. The post contact finish difference (tin vs. tin-lead) does not affect PCB assembly compatibility.

Q: What is the significance of the "LF" designation in the 63440-001LF part number?

A: The "LF" suffix indicates lead-free compliance. The 63440-001LF is RoHS compliant, whereas the original 63440-001 does not specify this certification. Both parts are suitable for standard solder assembly processes.

Q: Is the 71609-309LF a suitable replacement for the 63440-001?

A: No. The 71609-309LF is not a direct replacement. It differs in position count (18 vs. 32), mating pitch (0.100" vs. 0.079"), mounting type (surface mount right-angle vs. through-hole), and fastening mechanism (push-pull vs. latch lock). This part is only applicable if the design can be modified to accommodate these changes.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: connector type (receptacle), contact type (female socket), position count (32), position loading (28), mating pitch (0.079"), row spacing (0.079"), mounting type (through-hole), termination method (solder), fastening type (latch lock), and mating contact finish (gold). Deviations in any of these parameters indicate limited or no compatibility.

Q: Are there compliance differences between the 63440-001 and 63440-001LF?

A: Yes. The 63440-001LF is RoHS compliant and REACH affected, whereas the original 63440-001 is REACH unaffected with no specified RoHS status. Both parts maintain UL94 V-0 flammability rating and unlimited moisture sensitivity level. The compliance differences reflect manufacturing process updates in the active production variant.

Q: What inventory levels are available for these parts?

A: The 63440-001 (obsolete) has 989 units in stock. The 63440-001LF (active) has 1100 units in stock. The 71609-309LF (active) has 1538 units in stock. Inventory levels should be confirmed with the supplier for current availability.
