Amphenol ICC 86453-044 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 86453-044 is a rectangular connector header featuring a right-angle, through-hole mount configuration with 44 positions arranged in 2 rows at 2.00mm pitch. This Minitek® series component is designed for board-to-board or cable interconnection applications requiring push-pull fastening and solder termination.

The 86453-044 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol ICC 86453-044 is constrained by the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins, unshrouded, board-to-board or cable style
• Position Count & Row Configuration: 44 positions in 2 rows
• Pitch Specification: 0.079" (2.00mm) mating pitch and row spacing
• Mounting & Termination: Through-hole, right-angle mount with solder termination
• Fastening Mechanism: Push-pull fastening type
• Contact Material & Finish: Phosphor bronze with gold mating surface
• Electrical Performance: 2A current rating and 200V voltage rating
• Environmental Compliance: UL94 V-0 flammability rating

The identified substitute part, Samtec Inc. TSW-122-08-G-D-RA, shares the core functional architecture (header, male pins, 44 positions, 2 rows, through-hole right-angle mount, push-pull fastening, solder termination, phosphor bronze with gold finish). However, the TSW-122-08-G-D-RA operates at a different mating pitch of 0.100" (2.54mm), which represents a mechanical and electrical incompatibility with the original 2.00mm pitch specification. This pitch difference requires PCB redesign and cannot be considered a direct drop-in replacement without circuit board modification.

Parameter Comparison

Engineering Selection Recommendations

The Samtec TSW-122-08-G-D-RA is an active product with ROHS3 compliance and an extended operating temperature range (-55°C to 125°C versus -40°C to 105°C), providing improved environmental performance and regulatory alignment compared to the obsolete Amphenol ICC 86453-044.

However, the pitch incompatibility (2.54mm versus 2.00mm) is a fundamental mechanical constraint. Direct substitution without PCB redesign is not feasible. Any transition to the TSW-122-08-G-D-RA requires circuit board layout modification to accommodate the larger pitch spacing.

For applications requiring strict form-factor and pitch compatibility with the 86453-044, alternative sources or custom connector solutions from other manufacturers operating at 2.00mm pitch should be evaluated. The TSW-122-08-G-D-RA is suitable only for new designs or redesigned systems where the 2.54mm pitch is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the Samtec TSW-122-08-G-D-RA be used as a direct replacement for the Amphenol ICC 86453-044?

A: No. While both connectors share identical position count (44), row configuration (2), and core functional features (header, male pins, through-hole right-angle mount, push-pull fastening, solder termination), the mating pitch differs: 2.00mm for the 86453-044 versus 2.54mm for the TSW-122-08-G-D-RA. This pitch difference requires PCB redesign and prevents drop-in compatibility.

Q: What are the critical parameters that define substitution eligibility for the 86453-044?

A: Substitutes must match: connector type (header), contact type (male pin), position count (44), row count (2), mating pitch (0.079" / 2.00mm), row spacing (0.079" / 2.00mm), mounting style (through-hole right-angle), termination method (solder), and fastening type (push-pull). Deviations in any of these parameters indicate incompatibility.

Q: What is the significance of the pitch difference between these two connectors?

A: Pitch defines the center-to-center spacing between adjacent contacts. A 2.00mm pitch connector cannot physically mate with a 2.54mm pitch receptacle or socket. PCB footprints, via placement, and trace routing are all designed around the specified pitch. Changing pitch requires complete circuit board redesign.

Q: Does the Samtec TSW-122-08-G-D-RA offer any advantages over the obsolete 86453-044?

A: Yes. The TSW-122-08-G-D-RA is an active product with ROHS3 compliance, extended operating temperature range (-55°C to 125°C), and improved supply chain availability. These factors make it suitable for new designs or systems undergoing redesign, provided the 2.54mm pitch is acceptable.

Q: Are there other substitute options for the 86453-044 at the same 2.00mm pitch?

A: The provided substitute list identifies only the TSW-122-08-G-D-RA. For additional options at 2.00mm pitch, consultation with connector manufacturers specializing in fine-pitch rectangular headers is necessary.
