Cinch Connectivity Solutions 54A Terminal Lug Strip

Part Overview

The Cinch Connectivity Solutions 54A is a 6-position terminal lug strip with integrated ground positions (4 + 2 Ground), featuring a 1.875" (47.63mm) terminal lug pitch and single-end configuration. This component is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The part is constructed with XPC board material and cadmium-finished steel contacts, suitable for applications requiring reliable terminal connection and grounding capabilities.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Cinch 54A is determined by the following critical parameters:

• Position Configuration: 6 positions with 4 + 2 ground arrangement
• Terminal Type: Single-end terminal lug configuration
• Mounting Compatibility: 0.140" (4.66mm) mounting hole diameter
• Electrical Function: Terminal lug strip for connection and grounding

The Keystone Electronics 821 qualifies as a substitute based on matching position count, terminal type, and mounting hole diameter. However, the 821 exhibits significant dimensional differences in pitch (0.375" vs. 1.875") and board size, which affect physical layout and spacing requirements. This substitution is valid only when the application can accommodate the different pitch and board dimensions while maintaining the same electrical function and mounting interface.

Parameter Comparison

Engineering Selection Recommendations

The Keystone Electronics 821 is the identified substitute for the obsolete Cinch 54A. Selection of the 821 is appropriate when:

• The application requires an active, in-production terminal lug strip with 6-position configuration
• ROHS3 compliance is required for new designs or regulatory adherence
• Physical layout can accommodate the 0.375" pitch and 2.250" length dimensions
• The brass contact material with tin finish is compatible with the intended electrical environment

The 821 maintains functional equivalence through matching position count, terminal type, and mounting interface. The transition from cadmium to tin finish and from steel to brass contacts represents a material upgrade consistent with modern manufacturing standards and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can the Keystone 821 directly replace the Cinch 54A in existing designs?

A: Direct replacement requires verification of physical layout compatibility. The 821 has a significantly different pitch (0.375" vs. 1.875") and board dimensions, which may affect PCB layout and spacing. Mounting hole diameter (0.140") is identical, enabling mechanical compatibility at the mounting interface.

Q: What are the key differences between these parts?

A: The primary differences are pitch spacing, board dimensions, contact materials (brass vs. steel), contact finish (tin vs. cadmium), and board material (XP Phenolic vs. XPC). Both maintain the same 6-position configuration and terminal lug type.

Q: Is the Keystone 821 RoHS compliant?

A: Yes, the Keystone 821 is ROHS3 compliant, whereas the Cinch 54A is RoHS non-compliant. This makes the 821 suitable for applications with RoHS requirements.

Q: Are there any electrical performance differences?

A: Both parts function as terminal lug strips with identical position configuration and mounting interface. Contact material and finish differences (brass/tin vs. steel/cadmium) may affect corrosion resistance and electrical conductivity in specific environmental conditions.

Q: What is the inventory status of these parts?

A: The Cinch 54A is obsolete with 796 pieces in stock. The Keystone 821 is active with 2,871 pieces available, ensuring long-term supply availability for new production.
