74983-302004 Equivalent & Substitute Parts

Part Overview

The 74983-302004 is a 108-position backplane connector header manufactured by Amphenol ICC (FCI) from the Metral® 1000 series. This component is a male pin through-hole connector designed for high-speed applications with shielded construction and press-fit termination. The part is currently classified as obsolete, making identification of suitable substitutes essential for ongoing system support and new design implementations. The primary driver for substitution is the obsolete product status combined with active inventory availability of compliant alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74983-302004 is determined by strict equivalence across the following critical parameters:

• Connector type, style, and usage classification (Header, Male Pins, High Speed)
• Position count and contact layout (108 positions: 96 Signal, 12 Ground)
• Pitch specification (0.079" / 2.00mm)
• Row configuration (8 rows)
• Mounting and termination method (Through Hole, Press-Fit)
• Electrical ratings (1A current, operating temperature -55°C ~ 105°C)
• Physical and material properties (Gold contact finish, UL94 V-0, Shielded)
• Base product number (74983)

The 74983-302004LF meets all these criteria and is classified as a direct substitute. The primary distinction is product status transition from obsolete to active, coupled with RoHS compliance upgrade and packaging standardization.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can the 74983-302004LF be used as a direct replacement for the 74983-302004?

A: Yes. The 74983-302004LF is electrically and mechanically equivalent to the 74983-302004 across all specified parameters, including connector type, position count, pitch, contact layout, current rating, and operating temperature range. The parts are interchangeable without design modification.

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

A: The "LF" suffix indicates lead-free construction, reflecting RoHS compliance. The 74983-302004 is RoHS non-compliant, while the 74983-302004LF is RoHS compliant. This designation ensures the part meets current environmental and regulatory standards for electronic component manufacturing.

Q: Why is the original part number 74983-302004 classified as obsolete?

A: The obsolete status reflects the manufacturer's transition to RoHS-compliant alternatives. The 74983-302004LF represents the active, compliant successor in the Metral® 1000 series.

Q: Are there packaging differences between these parts?

A: The 74983-302004 packaging is not specified in the available data. The 74983-302004LF is supplied in tube packaging, which is the standard format for this connector type and facilitates automated assembly processes.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in connector type (Header, Male Pins), position count (108), pitch (0.079" / 2.00mm), row configuration (8), mounting method (Through Hole), termination type (Press-Fit), contact layout (96 Signal, 12 Ground), current rating (1A), operating temperature (-55°C ~ 105°C), and material properties (Gold finish, UL94 V-0, Shielded).

Q: Is the 74983-302004LF suitable for high-speed applications?

A: Yes. The 74983-302004LF is classified as a high-speed connector and maintains the shielded construction required for high-speed signal integrity. It is suitable for all applications previously using the 74983-302004.
