Amphenol ICC 69197-057H Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 69197-057H is a rectangular connector header featuring a vertical through-hole mount configuration with 40 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The BERGSTIK® II series connector provides board-to-board connectivity with press-fit and solder termination options, operating across a temperature range of -65°C to 130°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 69197-057H is determined by strict alignment of the following critical parameters:

• Connector positioning and pitch: 40 positions in 2 rows at 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing
• Contact configuration: Male pin contacts with square geometry
• Mounting interface: Through-hole board mount with push-pull fastening
• Electrical performance: 3A current rating and gold mating surface finish
• Environmental compliance: Operating temperature range of -65°C to 130°C and UL94 V-0 flammability rating
• Connector style: Board-to-board unshrouded or shrouded header configuration

The substitute part 64991-G20-4RLF meets these core substitution criteria while offering an active product status and improved compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 64991-G20-4RLF serves as the primary substitute for the obsolete 69197-057H based on matching core electrical and mechanical parameters. The substitute maintains identical position count, pitch spacing, contact configuration, and fastening methodology required for direct functional replacement.

Key differentiation factors include:

• Product Status: The substitute is active, ensuring long-term availability and supply chain continuity compared to the obsolete main part.
• RoHS Compliance: The substitute achieves RoHS compliance, aligning with modern regulatory requirements, whereas the main part is RoHS non-compliant.
• Shrouding Configuration: The substitute incorporates 4-wall shrouding, providing enhanced EMI shielding and mechanical protection compared to the unshrouded main part.
• Contact Material Specification: The substitute specifies phosphor bronze contact material with tin post finish, whereas the main part does not provide material details.

Selection of the 64991-G20-4RLF is appropriate for applications requiring active product status and regulatory compliance. Physical board layout modifications may be necessary to accommodate the increased insulation height (0.550" versus 0.100") and reduced overall contact length (0.548" versus 0.780") of the substitute.

Frequently Asked Questions (FAQ)

Q: Can the 64991-G20-4RLF directly replace the 69197-057H without PCB redesign?

A: The substitute maintains identical mating pitch (0.100"), row spacing (0.100"), position count (40), and through-hole mounting interface. However, the substitute features increased insulation height and reduced contact length. PCB footprint verification is required to confirm mechanical compatibility with existing board designs.

Q: What is the significance of the shrouding difference between these parts?

A: The main part is unshrouded, while the substitute incorporates 4-wall shrouding. Shrouding provides mechanical keying and EMI containment but increases the overall envelope dimensions. Board layout space must accommodate the larger shrouded profile.

Q: Are there temperature or flammability rating differences that affect application suitability?

A: The main part specifies -65°C to 130°C operating temperature and UL94 V-0 flammability rating. The substitute does not provide these specifications in the available data. Applications with specific thermal or flammability requirements should confirm substitute performance against design specifications.

Q: How do the contact finish specifications compare?

A: Both parts specify 30.0µin (0.76µm) gold plating on mating contacts. The substitute additionally specifies GXT™ enhanced gold plating and tin finish on posts (100.0µin / 2.54µm), whereas the main part does not detail post finish specifications.

Q: What compliance differences exist between these parts?

A: The substitute is RoHS compliant and REACH affected, while the main part is RoHS non-compliant and REACH unaffected. For applications subject to RoHS or REACH regulations, the substitute provides regulatory alignment.

Q: Does the substitute support the same termination methods?

A: The main part supports press-fit and solder termination. The substitute specifies kinked pin and solder termination. Termination method compatibility with existing assembly processes should be confirmed.
