Amphenol ICC 84688-103 High Speed Backplane Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 84688-103 is a 108-position high-speed backplane connector receptacle designed for board edge mounting applications. This connector features female sockets with press-fit termination, gold-plated contacts, and integrated shielding suitable for signal and ground distribution in high-speed interconnect systems.

The 84688-103 carries an obsolete product status, making identification of active equivalent parts essential for ongoing procurement and system maintenance. Direct substitutes maintain identical electrical and mechanical specifications while offering current manufacturing availability and updated compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

The 84688-103LF qualifies as a direct substitute based on identical electrical and mechanical parameters across all critical substitution criteria:

Matching Parameters:

• Connector type, position count, and pitch specifications
• Mounting configuration and termination method
• Contact layout, finish specification, and current rating
• Operating temperature range and flammability rating
• Series designation (Metral® 1000)

Differentiating Factors:

• Product status transition from obsolete to active
• Packaging format change (loose to tube)
• RoHS compliance upgrade (non-compliant to compliant)
• REACH status change (unaffected to affected)

The substitution is based strictly on maintained electrical and mechanical compatibility. No functional or performance differences exist between these parts.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement: The 84688-103LF is the appropriate selection. This part maintains full electrical and mechanical compatibility with the obsolete 84688-103 while offering active product status, current manufacturing support, and RoHS compliance certification. The tube packaging format is standard for active production inventory.

For Legacy System Maintenance: The 84688-103LF provides direct functional equivalence for replacement applications in existing systems originally specified with the 84688-103. The identical contact layout, pitch, mounting configuration, and electrical ratings ensure seamless integration without circuit redesign or board modification.

Compliance Considerations: The 84688-103LF meets current RoHS requirements and REACH regulatory status, making it suitable for applications subject to environmental compliance mandates. The 84688-103 remains available for legacy systems where non-compliant components are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 84688-103LF be used as a direct replacement for the 84688-103 in existing assemblies?

A: Yes. The 84688-103LF is electrically and mechanically identical to the 84688-103. All critical parameters—position count, pitch, mounting type, contact layout, current rating, and operating temperature range—are unchanged. No circuit modifications or board redesign is required.

Q: What is the significance of the "LF" suffix in the part number 84688-103LF?

A: The "LF" designation indicates lead-free construction and RoHS compliance. This reflects the manufacturing process update from the obsolete 84688-103 to meet current environmental regulations.

Q: Are there packaging differences between these parts?

A: Yes. The 84688-103 is supplied loose, while the 84688-103LF is packaged in tubes. This packaging change is standard for active production parts and does not affect electrical or mechanical performance.

Q: What is the contact layout for these connectors?

A: Both parts feature 90 signal contacts and 18 ground contacts distributed across 108 total positions in a 5-row configuration with 0.079" (2.00mm) pitch spacing.

Q: Are these connectors suitable for high-speed applications?

A: Yes. Both the 84688-103 and 84688-103LF are classified as high-speed backplane connectors with integrated shielding and board guide features designed for signal integrity in high-speed interconnect systems.

Q: What is the current rating for these connectors?

A: Both parts are rated for 1A per contact with a maximum operating temperature range of -55°C to 105°C and UL94 V-0 flammability certification.
