Amphenol ICC 73983-2001 High Speed Backplane Connector Header

Part Overview

The Amphenol ICC 73983-2001 is a 36-position high-speed backplane connector header designed for through-hole PCB mounting. This component features a male pin configuration with shielded design, suitable for applications requiring reliable signal and ground distribution across multiple rows. The part is classified as obsolete, making identification of compatible alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 73983-2001 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Header, Male Pins, High Speed)
• Position count and arrangement (36 positions, 5 rows)
• Pitch specification (0.079" / 2.00mm)
• Contact layout (30 Signal, 6 Ground)
• Mounting method (Through Hole, Press-Fit termination)
• Shielded design requirement
• Current and temperature ratings (1A, -55°C to 105°C)
• Flammability compliance (UL94 V-0)

The 73983-2001LF meets all these criteria as a direct substitute within the Metral® 1000 series. The primary distinction is product status and regulatory compliance, not electrical or mechanical function.

Parameter Comparison

Engineering Selection Recommendations

The 73983-2001LF is the direct functional equivalent of the 73983-2001. Both components share identical electrical and mechanical specifications within the Metral® 1000 series.

Selection between these parts depends on regulatory and compliance requirements:

• The 73983-2001LF is the active production part with RoHS compliance and REACH applicability, suitable for new designs and systems requiring modern regulatory adherence.
• The 73983-2001 is obsolete and RoHS non-compliant, appropriate only for legacy system maintenance where exact part matching is required and regulatory compliance is not a constraint.

Both parts are functionally interchangeable in applications requiring 36-position, 2.00mm pitch, shielded high-speed backplane headers with through-hole mounting and 1A current capacity across the -55°C to 105°C operating range.

Frequently Asked Questions (FAQ)

Q: Can the 73983-2001LF be used as a direct replacement for the 73983-2001?

A: Yes. The 73983-2001LF is electrically and mechanically identical to the 73983-2001. All connector specifications, pin configurations, and performance characteristics are equivalent. The primary differences are product status (active vs. obsolete) and regulatory compliance (RoHS compliant vs. non-compliant).

Q: What is the significance of the "LF" suffix in the part number?

A: The "LF" designation indicates lead-free composition, which aligns with RoHS compliance requirements. This is the primary distinguishing factor between the two part numbers.

Q: Are there any packaging differences between these parts?

A: The 73983-2001LF is supplied in tube packaging. The original 73983-2001 packaging specification is not provided in the technical data. Verify packaging requirements for your procurement process.

Q: Which part should be selected for new designs?

A: The 73983-2001LF should be selected for new designs. It is the active production part with current regulatory compliance (RoHS, REACH applicability) and ensures long-term availability and support.

Q: Can these parts be mixed in the same assembly?

A: Yes. Since both parts are functionally identical, they can be used interchangeably within the same PCB assembly without affecting electrical performance or mechanical fit.

Q: What are the key parameters that define substitution compatibility?

A: Substitution compatibility is determined by: 36-position count, 5-row configuration, 0.079" (2.00mm) pitch, through-hole mounting, press-fit termination, 30 signal and 6 ground contact layout, shielded design, 1A current rating, -55°C to 105°C operating range, and UL94 V-0 flammability rating.
