Amphenol ICC 91615-314 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 91615-314 is a 28-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 suitable substitutes essential for ongoing production and maintenance applications. The primary substitute maintains identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Substitute Part Grouping Explanation

Substitution of the 91615-314 with the 91615-314LF is based on strict equivalence across all critical electrical and mechanical parameters. Both parts share identical specifications for:

• Connector configuration (28-position receptacle, board-to-board)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Contact system (female socket, gold-plated mating surface)
• Mounting method (surface mount with solder termination)
• Physical dimensions (insulation height, mated stacking height)
• Material properties (thermoplastic glass-filled insulation, UL94 V-0 rating)
• Fastening mechanism (push-pull with board lock)

The primary difference between these parts is product status and compliance certification. The 91615-314LF represents the active production equivalent with current RoHS compliance and REACH affected status, whereas the 91615-314 is obsolete with non-compliant RoHS status.

Parameter Comparison

Engineering Selection Recommendations

The 91615-314LF is the direct functional equivalent for the obsolete 91615-314. Selection of the substitute part is based on:

• Identical electrical and mechanical specifications across all critical parameters
• Active product status ensuring continued availability and manufacturing support
• RoHS compliance certification, meeting current regulatory requirements for new designs and production
• REACH affected status reflecting current chemical substance compliance frameworks
• Equivalent performance in automotive, general purpose, industrial, and telecommunications applications

For applications requiring the 91615-314, the 91615-314LF provides full compatibility without design modification. The packaging difference (tube versus bulk) does not affect functional performance and may be accommodated through procurement processes.

Frequently Asked Questions (FAQ)

Q: Are the 91615-314 and 91615-314LF mechanically interchangeable?

A: Yes. Both parts have identical connector configurations, mating pitch (0.100"), row spacing, mounting type (surface mount), and physical dimensions including mated stacking height (10.81mm). They are direct mechanical substitutes.

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

A: The "LF" designation indicates lead-free compliance. The 91615-314LF meets RoHS requirements, whereas the 91615-314 does not. This reflects manufacturing process changes to eliminate restricted substances.

Q: Can the 91615-314LF be used in existing designs specified for the 91615-314?

A: Yes. The substitute part maintains all electrical and mechanical specifications required for board-to-board connectivity. No circuit design changes are necessary.

Q: What is the difference in packaging between these parts?

A: The 91615-314 is supplied in bulk packaging, while the 91615-314LF is supplied in tube packaging. Both contain the same connector; packaging affects only handling and storage logistics.

Q: Why is the 91615-314 listed as obsolete?

A: The 91615-314 has been superseded by the 91615-314LF as the active production part. Amphenol ICC has transitioned manufacturing to the lead-free compliant version to meet current regulatory standards.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts have identical contact materials (phosphor bronze), contact finishes (gold mating, tin post), and flammability ratings (UL94 V-0). Electrical performance is equivalent.

Q: What applications are these connectors suitable for?

A: Both parts are specified for automotive, general purpose, industrial, and telecommunications applications. The 28-position configuration with 0.100" pitch supports board-to-board interconnection in these sectors.
