Amphenol ICC 63453-032LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 63453-032LF is a 32-position receptacle connector from the Minitek® 2.00mm series, designed for board-to-board applications with through-hole solder termination. This connector features gold-plated mating contacts, push-pull fastening, and operates across an industrial temperature range of -55°C to 125°C. The part is currently active in production with 650 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when design requirements permit alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 63453-032LF are qualified based on the following critical parameters that determine functional interchangeability:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 32 positions at 0.079" (2.00mm) mating pitch
• Row Configuration: 2 rows with 0.079" (2.00mm) row spacing
• Mounting & Termination: Through-hole solder termination
• Fastening Mechanism: Push-pull fastening system
• Mating Contact Finish: Gold plating on mating surfaces
• Operating Temperature Range: -55°C to 125°C
• Electrical Performance: Current and voltage ratings sufficient for general purpose, industrial, and medical applications

The identified substitutes (MMS-116-01-F-DV and MMS-116-01-S-DV from Samtec Inc.) meet these core parameters, enabling direct replacement in board-to-board connector applications. Variations in contact finish thickness, insulation material composition, and post contact specifications do not affect the primary mating interface or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both Samtec MMS-116 series substitutes (MMS-116-01-F-DV and MMS-116-01-S-DV) are qualified alternatives to the Amphenol ICC 63453-032LF based on matching core electrical and mechanical specifications. All three parts maintain active product status and comply with applicable environmental regulations (RoHS3 for Samtec parts, RoHS for Amphenol ICC). The substitutes share identical connector architecture, position count, pitch, row configuration, and operating temperature range.

Selection between the two Samtec alternatives depends on contact finish thickness requirements for the mating interface. MMS-116-01-S-DV provides 30.0µin (0.76µm) gold plating, which aligns more closely with the original 8.00µin (0.203µm) specification. MMS-116-01-F-DV offers 3.00µin (0.076µm) plating for applications where minimal gold thickness is acceptable. Both parts feature higher current ratings (3.9A per contact) compared to the original 2A specification, providing additional margin in power delivery applications.

Minor dimensional variations exist in insulation height (0.175" vs. 0.177") and contact post length (0.115" vs. 0.098"), which remain within typical PCB design tolerances for board-to-board connector applications. Insulation material differs (LCP in Samtec parts versus PCT in Amphenol ICC), but both materials meet UL94 V-0 flammability requirements for industrial and medical applications.

Frequently Asked Questions (FAQ)

Q: Can MMS-116-01-F-DV and MMS-116-01-S-DV be used interchangeably with the 63453-032LF?

A: Yes. Both Samtec parts share identical connector type, position count, pitch, row spacing, mounting method, and fastening mechanism. The mating interface is functionally equivalent, enabling direct substitution in board-to-board applications.

Q: What is the difference between MMS-116-01-F-DV and MMS-116-01-S-DV?

A: The primary difference is mating contact gold finish thickness. MMS-116-01-S-DV provides 30.0µin (0.76µm) plating, while MMS-116-01-F-DV provides 3.00µin (0.076µm) plating. Both meet gold plating requirements for connector mating surfaces. Selection depends on application-specific contact durability and wear resistance requirements.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: Minor variations exist in insulation height (0.175" for Samtec versus 0.177" for Amphenol ICC) and contact post length (0.115" versus 0.098"). These differences fall within standard PCB design tolerances for through-hole connector applications and do not affect mating compatibility or board layout.

Q: Do the substitute parts support the same current and voltage ratings?

A: The Samtec substitutes support higher current ratings (3.9A per contact) compared to the original 2A specification. Voltage rating information is not provided for the Samtec parts; however, the connector architecture and materials are suitable for the original 200V application. Verify voltage requirements with application-specific design parameters.

Q: What is the difference in insulation material between these connectors?

A: The 63453-032LF uses glass-filled Polycyclohexylenedimethylene Terephthalate (PCT), while the Samtec MMS-116 series uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability ratings and are suitable for industrial and medical applications. Material selection does not affect electrical performance or mating interface compatibility.

Q: Are all three parts RoHS compliant?

A: Yes. The 63453-032LF is RoHS Compliant, while both Samtec substitutes are ROHS3 Compliant. All parts meet current environmental regulations for restricted substance use.
