PC-1645 Equivalent & Substitute Parts Reference

Part Overview

The PC-1645 is a 45-position rectangular connector plug housing manufactured by Hirose Electric Co Ltd as part of the Sumicon 1600 series. This component is classified as obsolete, making identification of suitable alternatives essential for ongoing system maintenance and new design implementations. The connector features a blue resin housing with male pin contacts, designed for crimp termination in free-hanging inline applications. Due to its obsolete status, sourcing equivalent or substitute components is necessary to ensure supply chain continuity and system compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PC-1645 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Plug housing with male pin contacts
• Position Count & Row Configuration: 45 positions arranged in 3 rows
• Mounting & Termination Method: Free hanging inline mounting with crimp contact termination
• Housing Material & Construction: Resin insulation material with flange feature
• Series Compatibility: Sumicon 1600 series designation
• Electrical & Environmental Ratings: MSL 1 (Unlimited) moisture sensitivity

The PC-1645(10) variant meets all substitution criteria while offering improved product status and compliance certifications. The primary distinction between the main part and its substitute is the housing color (blue versus black) and active product status, which does not affect electrical or mechanical compatibility within the Sumicon 1600 series framework.

Parameter Comparison

Engineering Selection Recommendations

The PC-1645(10) is the direct substitute for the obsolete PC-1645. Both components share identical electrical and mechanical specifications within the Sumicon 1600 series, including position count, row configuration, termination method, and environmental ratings.

The PC-1645(10) offers the following advantages:

• Active Product Status: Currently manufactured and supported by Hirose Electric Co Ltd, ensuring long-term availability and supply chain reliability
• RoHS Compliance: Certified RoHS compliant, meeting current regulatory requirements for electronic component manufacturing
• Increased Inventory: 1150 units in stock compared to 759 units of the obsolete variant, providing superior availability
• Bulk Packaging: Supplied in bulk packaging, suitable for production environments

The only functional difference is housing color (black versus blue). This distinction is cosmetic and does not affect electrical performance, mechanical fit, or system operation when integrated into applications originally designed for the PC-1645.

Frequently Asked Questions (FAQ)

Q: Can PC-1645(10) be used as a direct replacement for PC-1645 in existing designs?

A: Yes. The PC-1645(10) is electrically and mechanically identical to the PC-1645. All critical parameters—position count, row configuration, contact type, termination method, and environmental ratings—are identical. The housing color difference (black versus blue) is cosmetic and does not affect functionality or compatibility.

Q: What is the significance of the product status change from Obsolete to Active?

A: The active status of PC-1645(10) indicates current manufacturing and support by Hirose Electric Co Ltd. This ensures consistent availability, technical support, and compliance with current regulatory standards. Obsolete components face supply discontinuation and may lack manufacturer support.

Q: Are there any compatibility concerns when substituting PC-1645 with PC-1645(10)?

A: No compatibility concerns exist. Both components are part of the Sumicon 1600 series and share identical mechanical and electrical specifications. They are designed to interface with the same mating connectors and contact configurations.

Q: What does RoHS Compliance on PC-1645(10) mean for my application?

A: RoHS Compliance indicates that the PC-1645(10) meets Restriction of Hazardous Substances regulations, restricting the use of specific hazardous materials in electrical and electronic equipment. This is a regulatory requirement in many markets and ensures environmental and safety compliance.

Q: Does the packaging difference (bulk for PC-1645(10)) affect component performance?

A: No. Packaging type affects logistics and handling but does not influence electrical or mechanical performance. Bulk packaging is standard for production environments and offers cost efficiency for high-volume applications.

Q: Are contacts included with either the PC-1645 or PC-1645(10)?

A: No. Both components are connector housings only. Contacts must be sourced separately and crimped into the housing according to Hirose specifications and application requirements.
