Amphenol ICC 63453-322 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 63453-322 is a 22-position receptacle connector in the Minitek® 2.00mm series, designed for board-to-board applications with through-hole solder termination. This connector features gold-plated mating contacts, tin-plated posts, and a push-pull fastening mechanism. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 63453-322 is determined by strict equivalence in the following critical parameters:

• Connector type: Receptacle
• Number of positions: 22
• Pitch and row spacing: 0.079" (2.00mm)
• Mounting type: Through hole
• Termination method: Solder
• Fastening mechanism: Push-pull
• Contact finish: Gold mating surface
• Operating temperature range: -55°C ~ 125°C
• Electrical ratings: Minimum 2A current, 200V voltage

The identified substitutes maintain these core specifications while differing in secondary parameters such as insulation material, contact finish thickness, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 63453-322LF is the direct manufacturer equivalent from Amphenol ICC, maintaining identical electrical and mechanical specifications while offering active product status and RoHS compliance. This part is the primary substitute for obsolete 63453-322 applications.

The MMS-111-01-S-DV from Samtec Inc. provides an alternative from a different manufacturer with equivalent core functionality. This part offers higher current rating per contact (3.9A versus 2A) and uses liquid crystal polymer insulation instead of glass-filled PCT. The MMS series maintains the same pitch, row spacing, and push-pull fastening mechanism. Physical dimensions show minor variations in insulation height and contact post length that may require PCB layout verification.

Selection between 63453-322LF and MMS-111-01-S-DV depends on supply chain requirements, regulatory compliance mandates, and mechanical fit constraints within the application.

Frequently Asked Questions (FAQ)

Q: Can 63453-322LF directly replace 63453-322 in existing designs?

A: Yes. The 63453-322LF maintains identical electrical and mechanical specifications including pitch, row spacing, number of positions, current rating, voltage rating, and operating temperature range. The primary difference is product status (active versus obsolete) and regulatory compliance (RoHS compliant versus non-compliant).

Q: What are the physical differences between 63453-322LF and MMS-111-01-S-DV?

A: The MMS-111-01-S-DV has a contact post length of 0.115" (2.92mm) compared to 0.098" (2.50mm) for the 63453-322LF, and insulation height of 0.175" (4.45mm) versus 0.177" (4.50mm). These dimensional variations require verification against PCB through-hole depth and mating connector specifications.

Q: Are there electrical performance differences between these substitutes?

A: The MMS-111-01-S-DV is rated for 3.9A per contact, exceeding the 2A rating of the 63453-322 and 63453-322LF. All three parts operate across the same temperature range (-55°C ~ 125°C) and maintain gold-plated mating contacts for equivalent signal integrity.

Q: What packaging formats are available?

A: The 63453-322LF and MMS-111-01-S-DV are supplied in tube packaging. The original 63453-322 packaging format is not specified in available documentation.

Q: Do these parts meet current regulatory requirements?

A: The 63453-322LF is RoHS Compliant and REACH Affected. The MMS-111-01-S-DV is ROHS3 Compliant. The original 63453-322 is RoHS non-compliant and REACH Unaffected. Regulatory requirements for your application determine which substitute is appropriate.
