Terminal Lug Strip 56 - Equivalent & Substitute Parts

Part Overview

The Cinch Connectivity Solutions part number 56 is an 8-position terminal lug strip with integrated ground positions, designed for single-end lug termination applications. This component features a 2.625" (66.68mm) pitch configuration and is constructed with a XPC board material rated UL94 HB. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Cinch 56 is determined by the following critical parameters:

• Terminal Configuration: 8-position terminal lug strip with single-end lug termination and integrated ground positions
• Mounting Compatibility: 0.140" (4.66mm) mounting hole diameter
• Electrical Connectivity: Single row, 8-position arrangement with dedicated ground positions
• Physical Interface: Terminal lug termination type suitable for single-end applications

The Keystone Electronics part number 829 qualifies as a functional equivalent based on matching terminal configuration (8 positions with 6 + 2 ground arrangement), terminal type (single-end lug termination), mounting hole diameter (0.140"), and single-row layout. While pitch spacing differs (0.375" vs. 2.625"), both parts serve the same functional role in terminal lug strip applications with compatible mounting interfaces.

Parameter Comparison

Engineering Selection Recommendations

The Keystone Electronics 829 is the identified substitute for the obsolete Cinch 56 based on functional equivalence in terminal configuration and mounting interface. Key considerations for selection:

Product Status: The Cinch 56 is obsolete with no active manufacturing. The Keystone 829 maintains active product status with confirmed inventory availability (1334 pcs), ensuring supply chain continuity.

Compliance Profile: The Keystone 829 achieves ROHS3 compliance, whereas the Cinch 56 is RoHS non-compliant. For applications subject to RoHS regulations, the Keystone substitute provides regulatory alignment. Both parts maintain MSL 1 rating and REACH unaffected status.

Material and Contact Specifications: The Keystone 829 employs brass contacts with tin finish, compared to the Cinch 56's steel contacts with cadmium finish. Both configurations support single-end lug termination with identical mounting hole diameter (0.140"). Material differences do not affect functional compatibility in standard terminal lug strip applications.

Pitch Configuration: The Cinch 56 operates at 2.625" (66.68mm) pitch, while the Keystone 829 uses 0.375" (9.53mm) pitch. Pitch selection depends on application-specific spacing requirements and PCB layout constraints. Both maintain the 8-position, single-row configuration with integrated ground positions.

Frequently Asked Questions (FAQ)

Q: Can the Keystone 829 directly replace the Cinch 56 in existing applications?

A: Functional replacement is possible based on matching terminal configuration (8 positions, single-end lug type, 0.140" mounting holes). However, pitch spacing differs significantly (0.375" vs. 2.625"), requiring verification that the application layout accommodates the substitute's physical dimensions.

Q: What are the key differences between these two parts?

A: Primary differences include pitch spacing, contact material (brass vs. steel), contact finish (tin vs. cadmium), board material (XP Phenolic vs. XPC), and compliance status (ROHS3 compliant vs. RoHS non-compliant). Terminal configuration, mounting interface, and position count remain identical.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance is mandatory for applications subject to EU regulations or customer specifications requiring lead-free and restricted substance compliance. The Keystone 829's ROHS3 compliance addresses this requirement, whereas the obsolete Cinch 56 does not.

Q: Are there any electrical performance differences between cadmium and tin contact finishes?

A: Both cadmium and tin finishes provide adequate electrical conductivity for terminal lug strip applications. Contact finish selection depends on application environment, corrosion resistance requirements, and regulatory constraints. Tin finish (Keystone 829) is preferred in RoHS-compliant applications.

Q: How does pitch spacing affect component selection?

A: Pitch spacing determines the physical distance between terminal positions and directly impacts PCB layout, connector alignment, and mechanical fit. The 0.375" pitch (Keystone 829) creates a more compact footprint than the 2.625" pitch (Cinch 56). Application-specific spacing requirements must be verified before substitution.

Q: What is the significance of MSL 1 rating for both parts?

A: MSL 1 (Unlimited) indicates these components have no moisture sensitivity limitations and do not require special handling, storage, or baking procedures prior to assembly. Both parts are suitable for standard manufacturing environments without moisture control measures.
