Key Parameters

Substitute Part Grouping Explanation

The Keystone Electronics part number 800 qualifies as a functional substitute for the Cinch Connectivity Solutions 51 based on the following critical parameters:

Matching Parameters:

• Terminal Type: Terminal Lug, Single End
• Number of Positions: 2 (1 + 1 Ground)
• Number of Rows: 1
• Mounting Hole Diameter: 0.140" (4.66mm)
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN Classification: EAR99

The Keystone Electronics 800 maintains functional equivalence through identical terminal configuration, position count, and mounting specifications. Both components accommodate the same mounting hole diameter and share unrestricted moisture sensitivity ratings, enabling direct functional replacement in applications where the terminal lug strip serves as a connection interface.

Parameter Comparison

Engineering Selection Recommendations

The Keystone Electronics 800 is the identified substitute for the obsolete Cinch Connectivity Solutions 51. Selection of the Keystone 800 is supported by the following factors:

Product Status: The Cinch 51 is obsolete, making the active-status Keystone 800 the appropriate choice for continued component availability and supply chain continuity.

Compliance Posture: The Keystone 800 achieves ROHS3 compliance, whereas the Cinch 51 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the Keystone 800 provides compliant sourcing.

Functional Equivalence: Both components maintain identical terminal lug configuration, position count, and mounting hole specifications, ensuring mechanical and electrical compatibility in applications designed for the Cinch 51.

Physical Dimensions: The Keystone 800 exhibits a larger board footprint (0.750" L x 0.375" W x 0.062" H) compared to the Cinch 51 (0.375" W x 0.625" H). Space constraints within the target application must be evaluated prior to substitution.

Contact Material Differences: The Keystone 800 utilizes brass contacts with tin finish, whereas the Cinch 51 employs steel contacts with cadmium finish. These material differences may affect electrical conductivity and corrosion resistance characteristics in specific environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the Keystone Electronics 800 directly replace the Cinch Connectivity Solutions 51?

A: The Keystone 800 provides functional equivalence based on terminal type, position count, and mounting specifications. However, the larger board dimensions of the Keystone 800 require verification of available mounting space in the target application.

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

A: Primary differences include board size, contact material composition, contact finish, and compliance status. The Cinch 51 features a smaller footprint with steel/cadmium contacts and is RoHS non-compliant. The Keystone 800 has a larger footprint with brass/tin contacts and is ROHS3 compliant.

Q: Are there any electrical performance differences between cadmium-finished steel and tin-finished brass contacts?

A: Contact material and finish affect electrical conductivity, contact resistance, and corrosion resistance. Steel with cadmium finish and brass with tin finish exhibit different performance profiles. Application-specific electrical requirements must be evaluated.

Q: What is the significance of the RoHS compliance difference?

A: The Keystone 800 meets ROHS3 compliance requirements, whereas the Cinch 51 does not. Applications subject to RoHS regulatory mandates must utilize the Keystone 800 or identify alternative compliant components.

Q: Does the larger board size of the Keystone 800 affect compatibility?

A: The Keystone 800 board dimensions (0.750" L x 0.375" W x 0.062" H) exceed those of the Cinch 51 (0.375" W x 0.625" H). Physical space availability in the target assembly must be confirmed before substitution.

Q: Are both components available in the same packaging format?

A: The Cinch 51 packaging specification is not provided. The Keystone 800 is available in bulk packaging. Packaging requirements for the target application should be confirmed with the supplier.
