Amphenol ICC 63453-048 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 63453-048 is a 48-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 -55°C to 125°C. The part is currently listed as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 63453-048 is determined by the following critical parameters: 48-position count, 0.079" (2.00mm) mating pitch, 2-row configuration with 0.079" row spacing, through-hole solder termination, push-pull fastening, and gold-plated mating contacts. All listed substitutes meet these core mechanical and electrical interface requirements, ensuring physical and functional compatibility in board-to-board applications.

Variations in contact finish thickness, insulation material composition, contact shape, contact material, and post finish do not prevent substitution when the primary interface parameters remain constant. Operating temperature range, current rating, and voltage rating may differ between substitutes; selection should account for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 63453-048LF is the direct manufacturer equivalent from Amphenol ICC, maintaining identical electrical and mechanical specifications while offering active product status and RoHS compliance. This substitute is preferred for applications requiring continuity with the original Minitek® 2.00mm series design.

The 4-1734506-7 from TE Connectivity provides functional compatibility with identical mating pitch, row configuration, and contact arrangement. This substitute operates within a reduced temperature range (-40°C to 105°C) compared to the original specification and carries ROHS3 compliance. Selection of this part requires confirmation that the narrower operating temperature range meets application requirements.

The 833-13-048-10-002000 from Mill-Max Manufacturing Corp. maintains core mechanical compatibility and supports higher current capacity (3A versus 2A). This substitute features increased contact finish thickness on mating surfaces and differs in contact material composition (Beryllium Copper versus Phosphor Bronze). Applications requiring the enhanced current rating may benefit from this option, provided that material and finish differences are acceptable for the intended use.

Frequently Asked Questions (FAQ)

Q: Can the 63453-048LF directly replace the 63453-048 in existing designs?

A: Yes. The 63453-048LF maintains identical mating pitch (0.079"), row spacing, position count (48), and all critical interface dimensions. Both parts are from the Minitek® 2.00mm series and are mechanically and electrically interchangeable. The primary difference is product status (active versus obsolete) and RoHS compliance.

Q: What are the key differences between the TE Connectivity 4-1734506-7 and the original part?

A: The 4-1734506-7 shares the same mating pitch, row configuration, and position count. Differences include: operating temperature range (-40°C to 105°C versus -55°C to 125°C), contact finish thickness (10.0µin versus 8.00µin), contact length variation (0.102" versus 0.098"), and insulation material (Thermoplastic versus PCT Glass Filled). Voltage rating is specified as 250VAC versus 200V for the original.

Q: Is the Mill-Max 833-13-048-10-002000 suitable for high-current applications?

A: The 833-13-048-10-002000 supports 3A current rating compared to 2A for the original part, making it suitable for applications requiring higher current capacity. However, this part differs in contact material (Beryllium Copper), contact shape (Circular versus Square), and post finish (Gold versus Tin). These material differences should be evaluated for compatibility with mating connector specifications.

Q: What packaging options are available for these substitutes?

A: The 63453-048LF is supplied in Tube packaging. The 4-1734506-7 is supplied in Tray packaging. The 833-13-048-10-002000 is supplied in Bulk packaging. Packaging selection may affect handling, storage, and procurement workflows.

Q: Are all substitutes RoHS compliant?

A: The 63453-048LF is RoHS Compliant, and the 4-1734506-7 is ROHS3 Compliant. The original 63453-048 and the 833-13-048-10-002000 are both RoHS non-compliant. Applications subject to RoHS requirements should specify either the 63453-048LF or 4-1734506-7.

Q: What is the moisture sensitivity level for these connectors?

A: The 63453-048, 63453-048LF, and 4-1734506-7 all carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The 833-13-048-10-002000 is rated as Not Applicable for MSL, reflecting its bulk packaging and material composition.
