Cinch Connectivity Solutions 55 Terminal Lug Strip

Part Overview

The Cinch Connectivity Solutions part number 55 is a 7-position terminal lug strip with 2.250" (57.15mm) pitch spacing, designed for single-end terminal lug applications. This component features a 7-position configuration (5 standard positions plus 2 ground positions) with XPC board material and cadmium-plated steel contacts.

This part 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 for the Cinch Connectivity Solutions 55 is based on the following critical parameters:

• Position Configuration: 7-position terminal lug strip (5 + 2 ground positions)
• Terminal Type: Single-end terminal lug
• Mounting Compatibility: 0.140" (4.66mm) mounting hole diameter
• Number of Rows: Single row configuration
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The Keystone Electronics part number 824 qualifies as a substitute based on matching position count, terminal type, mounting hole diameter, and row configuration. However, this substitute differs in pitch spacing (0.375" vs. 2.250"), board dimensions, contact materials, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Keystone Electronics 824 is available as an active product with ROHS3 compliance, addressing the obsolescence of the Cinch 55. Both parts share identical position configuration, terminal type, and mounting hole specifications.

Selection of the Keystone 824 requires verification of pitch spacing compatibility with the application circuit board layout. The Keystone part operates at 0.375" (9.53mm) pitch versus the original 2.250" (57.15mm) pitch, resulting in significantly different board footprints and physical dimensions.

Contact material and finish differ between the two parts: the original uses cadmium-plated steel, while the substitute uses tin-plated brass. These material differences may affect electrical performance characteristics and environmental resistance in specific applications.

Frequently Asked Questions (FAQ)

Q: Can the Keystone 824 directly replace the Cinch 55 without circuit board modification?

A: Direct replacement is not possible without board redesign. The pitch spacing differs significantly (0.375" versus 2.250"), requiring new mounting hole locations and terminal positions on the circuit board.

Q: What are the key compatibility factors for this terminal lug strip substitution?

A: Critical compatibility factors include position count (7 positions with 2 ground), terminal type (single-end lug), and mounting hole diameter (0.140"). The Keystone 824 matches these specifications. Pitch spacing and board dimensions must be evaluated against specific application requirements.

Q: How do the contact materials affect substitution suitability?

A: The original part uses cadmium-plated steel contacts, while the substitute uses tin-plated brass. These materials have different electrical conductivity, corrosion resistance, and environmental performance characteristics. Application environment and electrical requirements determine material suitability.

Q: Is the Keystone 824 suitable for applications requiring RoHS compliance?

A: Yes. The Keystone 824 is ROHS3 compliant, whereas the original Cinch 55 is RoHS non-compliant. This makes the Keystone part suitable for applications with RoHS compliance requirements.

Q: What is the moisture sensitivity level for both parts?

A: Both the Cinch 55 and Keystone 824 have MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions for storage or handling.
