Amphenol ICC 91601-316 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 91601-316 is a 16-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications using surface mount technology. This connector features gold-plated mating contacts, tin-plated posts, and push-pull fastening in the Dubox™ series. The part is currently obsolete, making identification of suitable substitutes essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The 91601-316LF serves as a direct substitute for the 91601-316 based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• 16-position receptacle configuration with 0.100" (2.54mm) pitch
• Female socket contact type for board-to-board mating
• Surface mount termination with push-pull fastening
• Gold-plated mating contacts (30.0µin thickness) and tin-plated posts (78.7µin thickness)
• UL94 V-0 flammability rating
• Thermoplastic, glass-filled insulation with gray color
• Identical mated stacking height of 10.81mm

The primary distinction between these parts is product status and compliance certification, not electrical or mechanical function.

Parameter Comparison

Engineering Selection Recommendations

The 91601-316LF is the appropriate selection for new designs and ongoing production requirements. This part maintains full electrical and mechanical compatibility with the obsolete 91601-316 while offering the following advantages:

• Active product status ensures long-term availability and manufacturer support
• RoHS compliance satisfies current environmental and regulatory requirements
• REACH affected status indicates compliance with chemical substance regulations
• Higher inventory availability (2671 units) supports production continuity
• Tube packaging provides standard handling and storage compatibility

For legacy systems currently using 91601-316, the 91601-316LF provides direct functional equivalence without design modification or PCB rework.

Frequently Asked Questions (FAQ)

Q: Can 91601-316LF directly replace 91601-316 in existing assemblies?

A: Yes. Both parts share identical electrical and mechanical specifications including connector type, position count, pitch, contact materials, finishes, and physical dimensions. No design changes are required.

Q: What is the significance of the "LF" suffix in 91601-316LF?

A: The "LF" designation indicates lead-free compliance, reflecting RoHS regulatory requirements. The 91601-316LF meets current environmental standards while the 91601-316 does not.

Q: Are there any compatibility concerns between these parts?

A: No compatibility concerns exist. Both parts are Dubox™ series receptacles with identical mating interfaces, contact configurations, and physical envelopes.

Q: Why is the original 91601-316 marked as obsolete?

A: Product obsolescence reflects manufacturer discontinuation. The 91601-316LF represents the current production equivalent and should be used for all new designs and replenishment orders.

Q: What packaging differences exist between these parts?

A: The 91601-316 packaging is not specified in available documentation. The 91601-316LF is supplied in tube packaging, which is standard for surface mount connectors and compatible with automated assembly processes.

Q: Are there any thermal or electrical rating differences?

A: No differences exist in the provided specifications. Both parts share identical material flammability ratings (UL94 V-0) and contact finish specifications.
