Cinch Connectivity Solutions 56C Terminal Lug Strip Equivalent & Substitute Parts

Part Overview

The Cinch Connectivity Solutions 56C is an 8-position terminal lug strip with 1.875" (47.63mm) pitch spacing, designed for single-end terminal lug applications. This component features a 1-row configuration with integrated ground positions (6 + 2 Ground) and is constructed with XPC board material and cadmium-finished steel contacts.

The 56C is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for applications requiring this terminal lug strip configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Cinch 56C terminal lug strip is determined by the following critical parameters:

Position Configuration: The substitute must maintain 8 positions with 6 + 2 ground configuration to preserve circuit topology and grounding architecture.

Terminal Type: Single-end terminal lug configuration is required for mechanical and electrical compatibility with existing lug connections.

Pitch Spacing: The 1.875" (47.63mm) pitch establishes the physical spacing between terminal positions and determines board layout compatibility.

Number of Rows: Single-row configuration is mandatory for form factor compatibility.

Mounting Hole Diameter: The 0.140" (3.56mm) mounting hole diameter must be maintained for mechanical fastening compatibility.

Contact Material and Finish: While the original part uses cadmium-finished steel contacts, substitute parts may employ alternative contact materials and finishes provided they maintain electrical conductivity and mechanical durability within the application's electrical specifications.

Board Material: XPC or equivalent phenolic materials are acceptable for board substrate, provided flammability ratings meet or exceed UL94 HB classification.

Parameter Comparison

Engineering Selection Recommendations

Keystone Electronics 830 Substitute Consideration:

The Keystone 830 terminal lug strip shares the same position configuration (8 positions with 6 + 2 ground), terminal type (single-end lug), and row structure as the Cinch 56C. Both components feature identical mounting hole diameters (0.140") and unlimited moisture sensitivity ratings.

Critical Difference - Pitch Spacing:

The Keystone 830 operates at 0.375" (9.53mm) pitch spacing, whereas the Cinch 56C operates at 1.875" (47.63mm) pitch spacing. This represents a significant dimensional difference that affects board layout and terminal spacing. This pitch difference means the Keystone 830 is not a direct mechanical substitute for the Cinch 56C in existing designs.

Compliance Status:

The Cinch 56C is RoHS non-compliant with cadmium contact finish. The Keystone 830 is ROHS3 compliant with tin-finished brass contacts. For applications requiring RoHS compliance or cadmium-free construction, the Keystone 830 provides compliance benefits, though pitch spacing must be accommodated in the design.

Material Compatibility:

Both components use phenolic-based board materials (XPC and XP Phenolic respectively) with equivalent flammability characteristics. Contact material differs (steel vs. brass) and finish differs (cadmium vs. tin), but both configurations provide adequate electrical conductivity for terminal lug applications.

Frequently Asked Questions (FAQ)

Q: Can the Keystone 830 directly replace the Cinch 56C in existing assemblies?

A: Direct mechanical replacement is not possible. The Keystone 830 has a 0.375" pitch spacing compared to the Cinch 56C's 1.875" pitch spacing. This dimensional difference affects terminal spacing and board layout compatibility. Design modification is required to accommodate the different pitch.

Q: What are the critical parameters that must match for terminal lug strip substitution?

A: Critical matching parameters include: number of positions (8 with 6 + 2 ground configuration), terminal type (single-end lug), number of rows (1), and mounting hole diameter (0.140"). Pitch spacing is a critical dimensional parameter that determines physical compatibility with existing mounting and connection points.

Q: Does the Keystone 830 offer compliance advantages over the Cinch 56C?

A: Yes. The Keystone 830 is ROHS3 compliant with tin-finished brass contacts, whereas the Cinch 56C is RoHS non-compliant with cadmium-finished steel contacts. For applications requiring RoHS compliance or cadmium-free materials, the Keystone 830 provides regulatory compliance benefits.

Q: Are the contact materials interchangeable between these two parts?

A: Contact materials differ (steel vs. brass) and finishes differ (cadmium vs. tin). Both materials provide adequate electrical conductivity for terminal lug applications. Material selection should be based on application-specific electrical requirements, environmental exposure, and regulatory compliance mandates.

Q: What is the significance of the pitch spacing difference?

A: Pitch spacing (1.875" vs. 0.375") determines the physical distance between terminal positions. This affects board layout, terminal spacing, and mechanical mounting compatibility. A substitute part with different pitch spacing requires design modification and cannot be used as a direct drop-in replacement.

Q: Are both components suitable for unlimited moisture exposure?

A: Both the Cinch 56C and Keystone 830 have Moisture Sensitivity Level 1 (Unlimited), indicating they are not moisture-sensitive and do not require special handling or storage conditions related to moisture exposure.
