Amphenol ICC 84688-302 Backplane Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 84688-302 is a 216-position high-speed backplane connector receptacle with female sockets, designed for board edge mounting through press-fit termination. This connector features a 5-row configuration with 180 signal contacts and 36 ground contacts, operating across -55°C to 105°C with a 1A current rating per contact.

The 84688-302 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.

Substitute Part Grouping Explanation

Substitution of the 84688-302 is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute, 84688-302LF, maintains identical specifications for connector type, position count, pitch, row configuration, mounting method, termination style, contact layout, finish specification, current rating, and operating temperature range.

The substitution is valid based on the following critical parameters:

• 216-position count with identical 5-row configuration
• 0.079" (2.00mm) pitch spacing
• Board edge, through-hole, right-angle mounting
• Press-fit termination method
• 180 signal and 36 ground contact layout
• Gold contact finish with identical thickness specification
• 1A per-contact current rating
• -55°C to 105°C operating temperature range
• UL94 V-0 flammability rating

The primary distinction between the main part and substitute relates to product status and compliance certifications rather than functional or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 84688-302LF serves as the direct active equivalent to the obsolete 84688-302. Selection between these parts should be based on compliance requirements and product lifecycle considerations.

The 84688-302 remains available in current inventory but carries obsolete status with RoHS non-compliant certification. This part is suitable for legacy system maintenance where existing designs and compliance frameworks are established.

The 84688-302LF is the recommended selection for new designs and ongoing procurement. This part maintains active product status with full RoHS compliance, ensuring alignment with current regulatory requirements and long-term supply chain stability. The LF designation indicates lead-free manufacturing, reflecting modern environmental and safety standards.

Both parts are electrically and mechanically identical across all functional parameters. The choice between them depends on project compliance mandates, supply chain strategy, and regulatory environment rather than technical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Are the 84688-302 and 84688-302LF electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including 216-position count, 1A current rating per contact, operating temperature range of -55°C to 105°C, and contact layout of 180 signal and 36 ground contacts.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance certifications. The 84688-302 is obsolete and RoHS non-compliant, while the 84688-302LF is active and RoHS compliant. The LF suffix indicates lead-free manufacturing. All mechanical and electrical specifications remain identical.

Q: Can I use the 84688-302LF as a direct replacement for the 84688-302 in existing designs?

A: Yes. The 84688-302LF is a direct mechanical and electrical substitute. No design modifications are required. The connector maintains the same board edge mounting, press-fit termination, pitch spacing, and contact configuration.

Q: What does the packaging difference mean?

A: The 84688-302 ships in bulk packaging, while the 84688-302LF ships in tube packaging. This is a logistics consideration only and does not affect connector performance or compatibility.

Q: Why should I transition from 84688-302 to 84688-302LF?

A: The 84688-302 carries obsolete status, indicating discontinued manufacturing. The 84688-302LF is actively manufactured and offers RoHS compliance, ensuring regulatory alignment and long-term supply availability for new projects and ongoing maintenance.

Q: Are there any mechanical compatibility issues between these connectors?

A: No. Both connectors share identical mechanical specifications: 5-row configuration, 0.079" (2.00mm) pitch, board edge through-hole right-angle mounting, and press-fit termination. They are mechanically interchangeable.
