Amphenol ICC 51694-002 Backplane Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 51694-002 is a 32-position right-angle blade power header connector designed for board edge, through-hole mounting applications. This connector features male pins and blades with a 0.100" (2.54mm) pitch, organized in 4 rows with a typical contact layout of 24 signal and 8 power positions. The connector is part of the PwrBlade® series and incorporates board lock and mating guide features for secure assembly.

The 51694-002 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production and maintenance requirements for systems utilizing this connector specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 51694-002 is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Header with male pins and blades, blade power configuration
• Position Count & Arrangement: 32 positions in 4-row configuration
• Pitch & Spacing: 0.100" (2.54mm) pitch maintained
• Mounting Configuration: Board edge, through-hole, right-angle orientation
• Contact Layout: 24 signal and 8 power positions
• Termination Method: Solder termination
• Contact Finish Specification: Gold or Gold, GXT™ finish at 30.0µin (0.76µm) thickness
• Environmental Ratings: UL94 V-0 flammability, -20°C ~ 105°C operating temperature

Parts meeting all these parameters are classified as direct substitutes. Variations in product status, RoHS compliance, or packaging format do not affect electrical or mechanical compatibility when these core parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The 51694-002LF is a direct electrical and mechanical substitute for the 51694-002. Both connectors maintain identical specifications across all critical parameters: connector type, position count, pitch, mounting configuration, contact layout, termination method, contact finish, and environmental ratings.

The primary distinction between these parts is product status and compliance posture. The 51694-002 is obsolete and RoHS non-compliant, while the 51694-002LF is active and RoHS compliant. For new designs or systems requiring regulatory compliance with current environmental standards, the 51694-002LF is the appropriate selection. For legacy system maintenance where the original 51694-002 specification must be preserved, the 51694-002LF provides full compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 51694-002LF be used as a direct replacement for the 51694-002 in existing assemblies?

A: Yes. The 51694-002LF is electrically and mechanically identical to the 51694-002. All connector parameters—position count, pitch, mounting type, contact layout, and termination—are equivalent. No board redesign or assembly procedure modification is required.

Q: What is the significance of the "LF" suffix in the 51694-002LF part number?

A: The "LF" designation indicates lead-free construction, reflecting RoHS compliance. This part meets current environmental regulations while maintaining full compatibility with the original 51694-002 specification.

Q: Are there packaging differences between the 51694-002 and 51694-002LF?

A: The 51694-002LF is supplied in tray packaging. The original 51694-002 packaging format is not specified in the available data. Packaging differences do not affect connector performance or compatibility; they relate only to handling, storage, and logistics.

Q: Why is the 51694-002 classified as obsolete?

A: Obsolescence reflects the manufacturer's discontinuation of this part number in favor of the active 51694-002LF variant. The functional specification remains valid; however, new inventory procurement must transition to the 51694-002LF.

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

A: No. Both connectors share identical electrical specifications: contact finish (Gold or Gold, GXT™ at 30.0µin thickness), operating temperature range (-20°C ~ 105°C), and material flammability rating (UL94 V-0). Electrical performance is equivalent.
