Amphenol ICC 91618-318 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 91618-318 is a 36-position receptacle connector in the Dubox™ series, designed for board-to-board applications with 0.100" (2.54mm) pitch spacing. This surface mount connector features gold-plated mating contacts, push-pull fastening, and board lock functionality. The part is currently listed as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 91618-318 is determined by strict equivalence across the following critical parameters:

• Connector geometry: 36 positions, 2 rows, 0.100" pitch in both mating and row spacing
• Electrical interface: Receptacle configuration with female socket contacts, gold mating finish
• Mechanical interface: Surface mount termination with push-pull fastening and board lock
• Material compliance: UL94 V-0 flammability rating and thermoplastic glass-filled insulation
• Contact material and finish: Phosphor bronze with tin post finish

The 91618-318LF meets all these criteria as an active equivalent part. The primary difference is packaging format (tube versus unspecified) and regulatory compliance status (RoHS compliant and REACH affected versus non-compliant and unaffected).

Parameter Comparison

Engineering Selection Recommendations

The 91618-318LF is the direct active equivalent for the obsolete 91618-318. Both parts share identical mechanical and electrical specifications, including connector geometry, contact configuration, and material properties. The 91618-318LF is preferred for new designs and ongoing procurement due to its active product status and RoHS compliance. For applications requiring RoHS non-compliant components, the original 91618-318 remains available in inventory. The REACH compliance difference reflects regulatory classification changes and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 91618-318LF be used as a direct replacement for the 91618-318?

A: Yes. Both parts are identical in all mechanical and electrical parameters, including connector type, position count, pitch spacing, contact finish, and mounting configuration. The primary difference is product status and regulatory compliance.

Q: What is the difference between the 91618-318 and 91618-318LF?

A: The 91618-318LF is the active production equivalent. It is RoHS compliant and REACH affected, whereas the 91618-318 is RoHS non-compliant and REACH unaffected. Packaging differs (tube for the LF variant). All functional specifications are identical.

Q: Are there any compatibility concerns when substituting these parts?

A: No. The parts are mechanically and electrically interchangeable. Both feature identical 36-position, 2-row configuration with 0.100" pitch, gold mating contacts, push-pull fastening, and board lock functionality.

Q: Which part should be selected for new designs?

A: The 91618-318LF should be selected for new designs due to its active product status and RoHS compliance alignment with current regulatory requirements.

Q: Does packaging format affect compatibility?

A: No. The tube packaging of the 91618-318LF is a logistics consideration only and does not affect electrical or mechanical compatibility with the original part.
