Amphenol ICC 77773-302 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 77773-302 is a shrouded vertical header connector with 35 positions at 2.54mm pitch, designed for through-hole board-to-cable/wire applications. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The connector features a single-row configuration with friction lock fastening and gold-plated mating contacts suitable for 3A current applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 77773-302 is determined by the following critical parameters: connector type (header), contact type (male pin), pitch (2.54mm), number of positions (35), mounting method (through hole), shrouding configuration (2-wall), current rating (3A), and operating temperature range (-40°C to 125°C).

The primary substitute, 77773-302LF, maintains identical electrical and mechanical specifications while offering improved compliance status. This part is functionally equivalent with no design modifications required.

The secondary substitute, 98414-G06-30ULF, represents a different connector family (Minitek® 2.00mm series) with different pitch (2.00mm), position count (30), row configuration (2 rows), and current rating (2A). This part is not directly interchangeable and requires circuit board redesign.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production transitions, the 77773-302LF is the recommended direct substitute. This part maintains identical pitch (2.54mm), position count (35), row configuration (1 row), current rating (3A), and operating temperature range (-40°C to 125°C). The primary advantage is active product status with RoHS compliance and REACH affected designation, eliminating obsolescence risk. The contact finish post material changes from tin-lead to tin, which is compatible with modern soldering processes.

The 98414-G06-30ULF should only be considered if circuit board redesign is acceptable. This connector operates at a different pitch (2.00mm), reduced position count (30), dual-row configuration, and lower current rating (2A). Board layout modifications are mandatory for this substitution.

Frequently Asked Questions (FAQ)

Q: Can the 77773-302LF be used as a direct replacement for the 77773-302 without PCB modifications?

A: Yes. The 77773-302LF maintains identical electrical and mechanical specifications including pitch (2.54mm), position count (35), single-row configuration, current rating (3A), and operating temperature range (-40°C to 125°C). No circuit board redesign is required.

Q: What is the primary difference between the 77773-302 and 77773-302LF?

A: The 77773-302LF is the active production equivalent with RoHS compliance and improved availability. The contact finish post material changes from tin-lead to tin. The main part is obsolete; the LF variant is actively manufactured.

Q: Is the 98414-G06-30ULF compatible with existing 77773-302 applications?

A: No. The 98414-G06-30ULF operates at 2.00mm pitch versus 2.54mm, contains 30 positions in a 2-row configuration versus 35 positions in 1 row, and has a 2A current rating versus 3A. Circuit board redesign is required for this substitution.

Q: What packaging options are available for the substitute parts?

A: The 77773-302LF is supplied in tube packaging. The 98414-G06-30ULF is also supplied in tube packaging. Packaging specifications should be confirmed with the supplier for specific order quantities.

Q: Are there compliance differences between the main part and the 77773-302LF substitute?

A: Yes. The 77773-302 is RoHS non-compliant with tin-lead post finish. The 77773-302LF is RoHS compliant with tin post finish and REACH affected status, making it suitable for applications requiring modern environmental compliance standards.
