Amphenol ICC 63453-032 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 63453-032 is a 32-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 operates across -55°C to 125°C with a 2A current rating at 200V. The part is currently listed as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications in general purpose, industrial, and medical equipment.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 63453-032 is determined by strict equivalence across the following critical parameters: connector type (receptacle), number of positions (32), 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 contact finish at mating surface (gold). All identified substitutes meet these core mechanical and electrical interface requirements, ensuring physical and functional compatibility in board-to-board applications.

The four substitute parts identified are:

1. 63453-032LF (Amphenol ICC) - Direct variant with active product status and RoHS compliance
2. 3-1734506-9 (TE Connectivity AMP Connectors) - AMPMODU series equivalent with active status
3. 833-13-032-10-002000 (Mill-Max Manufacturing Corp.) - 833 series alternative with enhanced current rating
4. MMS-116-01-S-DV (Samtec Inc.) - MMS series option with ROHS3 compliance and higher current capacity

Parameter Comparison

Engineering Selection Recommendations

63453-032LF is the primary direct substitute, offering identical mechanical and electrical specifications to the obsolete 63453-032 while maintaining active product status. This variant achieves RoHS compliance and is packaged in tube format, making it suitable for applications requiring regulatory adherence without design modification.

3-1734506-9 (TE Connectivity AMPMODU series) provides an alternative from a major connector manufacturer with active product status and RoHS compliance. The operating temperature range is reduced to -40°C to 105°C, which may limit suitability for applications requiring the full -55°C to 125°C range of the original part.

833-13-032-10-002000 (Mill-Max 833 series) offers enhanced current capacity at 3A and maintains the full -55°C to 125°C operating range. However, this part retains RoHS non-compliant status, matching the original part's regulatory classification. Contact geometry differs (circular versus square), and contact material is beryllium copper rather than phosphor bronze.

MMS-116-01-S-DV (Samtec MMS series) delivers the highest current rating at 3.9A per contact with ROHS3 compliance. This option supports applications with elevated current demands while meeting modern regulatory requirements. Material flammability rating is not specified for this variant.

For new designs or production requiring regulatory compliance, 63453-032LF or MMS-116-01-S-DV are preferred. For legacy systems matching the original specifications, 63453-032LF provides the closest equivalent. Applications with reduced temperature requirements may consider 3-1734506-9.

Frequently Asked Questions (FAQ)

Q: Can 63453-032LF be used as a direct replacement for 63453-032?

A: Yes. The 63453-032LF maintains identical mechanical and electrical interface specifications, including 32 positions, 0.079" (2.00mm) pitch, 2-row configuration, through-hole solder termination, push-pull fastening, and gold mating contacts. The primary difference is active product status and RoHS compliance.

Q: What are the key differences between the substitute options?

A: All substitutes maintain the core 32-position, 2.00mm pitch, board-to-board interface. Variations include current rating (2A to 3.9A), operating temperature range (-40°C to -55°C minimum), contact material composition, and regulatory compliance status. Selection depends on application requirements for current capacity, temperature extremes, and regulatory environment.

Q: Does the contact finish thickness variation affect compatibility?

A: Contact finish thickness differences (8.00µin to 30.0µin at mating surface) do not affect mechanical mating or electrical interface compatibility. These variations represent different manufacturing specifications within acceptable contact durability ranges for the 2.00mm pitch class.

Q: Are there packaging considerations for production planning?

A: Yes. 63453-032LF is supplied in tube packaging, 3-1734506-9 in tray, 833-13-032-10-002000 in bulk, and MMS-116-01-S-DV in tube. Packaging selection impacts handling, storage, and automated assembly processes. Verify packaging compatibility with existing production equipment and supply chain requirements.

Q: Which substitute is recommended for medical applications?

A: The original 63453-032 lists medical applications. For medical equipment requiring active product status and regulatory compliance, 63453-032LF (RoHS compliant, active status) or MMS-116-01-S-DV (ROHS3 compliant, active status) are appropriate selections. Verify specific medical device regulatory requirements with application engineering.

Q: What is the impact of operating temperature range differences?

A: The 3-1734506-9 operates at -40°C to 105°C, compared to -55°C to 125°C for the original and most substitutes. This restriction eliminates suitability for applications requiring full temperature extremes, particularly industrial or aerospace environments with extended low-temperature operation.
