Amphenol ICC 63453-044 44-Position Rectangular Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 63453-044 is a 44-position receptacle connector in the Minitek® 2.00mm series, designed for board-to-board applications with 0.079" (2.00mm) pitch spacing. This connector features through-hole solder termination, gold-plated mating contacts, and operates across -55°C to 125°C. The part is currently obsolete, necessitating identification of functionally equivalent alternatives from active product lines that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the 63453-044 is determined by strict equivalence in the following parameters: connector type (receptacle), number of positions (44), mating pitch (0.079" / 2.00mm), number of rows (2), row spacing (0.079" / 2.00mm), mounting type (through hole), termination method (solder), fastening type (push-pull), and operating temperature range (-55°C ~ 125°C).

Substitute parts are grouped into two categories:

Direct Amphenol ICC Substitutes: Parts maintaining identical series designation (Minitek® 2.00mm) with full position loading (44 positions loaded).

Cross-Manufacturer Alternatives: Parts from Mill-Max Manufacturing Corp. and Samtec Inc. that satisfy all core electrical and mechanical parameters while offering active product status and enhanced compliance certifications.

Engineering Selection Recommendations

Primary Recommendation: 63453-044LF

The 63453-044LF is the direct successor within the Amphenol ICC Minitek® 2.00mm series. It maintains identical electrical and mechanical specifications to the 63453-044 while offering active product status and RoHS compliance. This part is the preferred choice for direct replacement in existing designs without modification.

Secondary Recommendation: MMS-122-01-LM-DV

The Samtec MMS-122-01-LM-DV provides cross-manufacturer compatibility with all 44 positions loaded. It offers ROHS3 compliance and higher current rating (3.9A per contact) compared to the original 2A specification. The insulation material differs (Liquid Crystal Polymer vs. PCT), and contact post length is increased (0.115" vs. 0.098"), which may require PCB layout verification for applications with tight vertical clearance constraints.

Alternative Options: MMS-122-01-F-DV, MMS-122-01-H-DV

These Samtec alternatives provide full position loading with ROHS3 compliance. MMS-122-01-H-DV includes gold post finish (vs. tin), offering enhanced corrosion resistance. Both require design validation due to increased contact post length and different insulation material composition.

Partial Position Loading Alternatives: MMS-122-01-L-DV Series

The MMS-122-01-L-DV-20, MMS-122-01-L-DV-01, MMS-122-01-L-DV-10, and MMS-122-01-L-DV-25 variants load 43 of 44 positions. These are suitable only for applications where one position can remain unloaded without functional impact.

Cross-Manufacturer Option: 833-13-044-10-002000

The Mill-Max 833-13-044-10-002000 maintains 44-position full loading and core mechanical compatibility. However, it features circular contact geometry (vs. square), beryllium copper contact material (vs. phosphor bronze), and gold post finish. These material differences require electrical performance validation in the target application.

Frequently Asked Questions (FAQ)

Q: Can 63453-044LF be used as a direct drop-in replacement for 63453-044?

A: Yes. The 63453-044LF maintains identical pitch, row spacing, position count, mounting type, and operating temperature range. It is the recommended direct replacement.

Q: What is the primary difference between Amphenol ICC and Samtec alternatives?

A: Samtec MMS series connectors feature Liquid Crystal Polymer (LCP) insulation material versus Polycyclohexylenedimethylene Terephthalate (PCT) in Amphenol ICC parts. Samtec parts also provide higher current ratings (3.9A per contact vs. 2A) and increased contact post length (0.115" vs. 0.098"). These differences require design validation for PCB layout and electrical performance.

Q: Are the MMS-122-01-L-DV variants with 43 loaded positions suitable replacements?

A: Only if the application design permits one unloaded position. These parts are not suitable for designs requiring all 44 positions to be active.

Q: What compliance certifications differ between substitute options?

A: The original 63453-044 is RoHS non-compliant. The 63453-044LF is RoHS compliant. Samtec MMS series parts are ROHS3 compliant. The Mill-Max 833-13-044-10-002000 is RoHS non-compliant. Select based on regulatory requirements for the target application.

Q: Does contact finish thickness affect electrical performance?

A: Contact finish thickness variations (ranging from 3.00µin to 30.0µin) are within acceptable ranges for general-purpose applications. Selection should be based on application environment and corrosion resistance requirements.

Q: What packaging options are available?

A: The 63453-044LF is supplied in tube packaging. Samtec MMS-122-01-LM-DV and MMS-122-01-L-DV-20 are supplied in tube packaging. The Mill-Max 833-13-044-10-002000 is supplied in bulk packaging. Verify packaging requirements for procurement and assembly processes.

Q: Can Samtec and Mill-Max parts be mixed in the same design?

A: Mechanical and electrical compatibility exists between all listed substitutes for the core 44-position, 2.00mm pitch receptacle function. However, design validation is required when mixing manufacturers due to variations in insulation material, contact geometry, and post length.
