Amphenol ICC 84688-902SLF Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 84688-902SLF is a 216-position high-speed backplane connector receptacle designed for board edge, through-hole mounting applications. This connector features female sockets with right-angle orientation and is part of the Metral® 1000 series. The product is currently obsolete, making identification of compatible substitute parts essential for legacy system maintenance and board redesigns. The 216-position configuration with 180 signal and 36 ground contacts supports high-density interconnect requirements in backplane applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute compatibility for the 84688-902SLF is determined by the following critical parameters:

• Connector Series: Both parts must belong to the Metral® 1000 series to ensure mechanical and electrical compatibility
• Connector Type: Receptacle configuration with female sockets is required
• Mounting Style: Board edge, through-hole, right-angle orientation must be maintained
• Pitch: 0.079" (2.00mm) pitch is mandatory for contact alignment
• Termination Method: Press-fit termination ensures consistent board integration
• Electrical Ratings: Current rating (1A) and operating temperature range (-55°C ~ 105°C) must be met or exceeded
• Safety Compliance: UL94 V-0 flammability rating must be maintained

The identified substitute part 84688-102LF shares the same series, connector type, mounting configuration, pitch, termination method, and electrical/thermal specifications. However, it differs in position count (72 vs. 216), which affects its application scope.

Parameter Comparison

Engineering Selection Recommendations

The 84688-102LF serves as a functional substitute for the obsolete 84688-902SLF within the constraints of application requirements. Both connectors share identical electrical, thermal, and mechanical specifications, including current rating, operating temperature range, and flammability compliance.

The primary distinction is position count: the 84688-102LF provides 72 positions compared to the 216 positions of the main part. This substitution is applicable only when system requirements can accommodate the reduced contact density. The 84688-102LF's active product status ensures ongoing availability and supply chain continuity, whereas the 84688-902SLF's obsolete status limits procurement options.

The 84688-102LF includes RoHS compliance certification and specified gold contact finish (30.0µin thickness), providing enhanced environmental and corrosion resistance compared to the main part's unspecified contact finish. These characteristics support long-term reliability in demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the 84688-102LF directly replace the 84688-902SLF in existing designs?

A: Direct replacement is possible only if the application requires 72 or fewer contact positions. The identical pitch (0.079"), mounting configuration (board edge, through-hole, right angle), and electrical specifications (1A current, -55°C to 105°C operating range) ensure mechanical and electrical compatibility. Board redesign is necessary if the original design utilizes more than 72 contacts.

Q: What are the key compatibility criteria between these connectors?

A: Compatibility is determined by series membership (Metral® 1000), connector type (receptacle with female sockets), pitch (0.079"), mounting style (board edge through-hole right angle), termination method (press-fit), and electrical ratings (1A, -55°C to 105°C, UL94 V-0). Both parts meet these criteria.

Q: Does the 84688-102LF's RoHS compliance affect compatibility?

A: RoHS compliance is a regulatory and environmental attribute that does not affect electrical or mechanical compatibility. The 84688-102LF's RoHS compliance status supports compliance requirements in regulated markets and does not introduce incompatibility with the main part's specifications.

Q: What is the significance of the contact finish difference?

A: The 84688-102LF specifies gold plating (30.0µin thickness), while the main part does not specify contact finish. Gold plating provides superior corrosion resistance and contact reliability, particularly in high-reliability applications. This represents an enhancement rather than a limitation for substitution.

Q: How does the position count difference affect substitution decisions?

A: Position count is the primary limiting factor for substitution. The 84688-102LF's 72-position configuration is suitable only for applications requiring 72 or fewer contacts. Applications requiring the full 216-position density of the main part cannot use this substitute without significant board redesign to reduce contact requirements.

Q: Is the active product status of the 84688-102LF significant for procurement?

A: Yes. The 84688-102LF's active status ensures ongoing manufacturing and availability, whereas the 84688-902SLF's obsolete status indicates discontinued production. For new designs or legacy system maintenance requiring connector procurement, the active status of the 84688-102LF provides supply chain reliability.
