Keystone Electronics 15110 Turret Board - Equivalent & Substitute Parts

Part Overview

The Keystone Electronics 15110 is a 66-position turret board featuring 0.375" (9.53mm) turret terminals with single-end, double-turret configuration. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing production and maintenance applications. The board utilizes XP phenolic material and is designed for applications requiring reliable turret terminal connectivity in a compact 13.125" x 1.188" form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Keystone Electronics 15110 is determined by strict equivalence across the following critical parameters:

• Number of Positions: 66 positions (exact match required)
• Pitch: 0.375" (9.53mm) turret spacing (exact match required)
• Terminal Type: Turret, Single End, Double Turret configuration (exact match required)
• Number of Rows: 2 rows (exact match required)
• Row Spacing: 0.750" (19.05mm) (exact match required)
• Board Size: 13.125" L x 1.188" W x 0.093" H (exact match required)
• Contact Material: Brass (exact match required)
• Contact Finish: Tin (exact match required)
• Mounting Hole Diameter: 0.120" (3.05mm) (exact match required)
• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The primary allowable variation is board material, where XP phenolic and glass epoxy substrates are functionally interchangeable when all other electrical and mechanical parameters remain identical. This substitution is valid because both materials meet the same RoHS3 compliance and MSL requirements while maintaining identical dimensional and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Keystone Electronics 15310 is a direct functional equivalent to the obsolete 15110 turret board. Selection of the 15310 is supported by the following engineering criteria:

Compliance & Certification: Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility with existing applications.

Product Status: The 15310 carries active product status, providing supply chain continuity and availability advantages over the obsolete 15110. This status ensures ongoing manufacturing support and documented specifications.

Dimensional & Electrical Equivalence: All critical mechanical parameters—position count, pitch, row configuration, board dimensions, and mounting specifications—are identical between the two parts. The brass contact material with tin finish is preserved, maintaining electrical performance characteristics.

Material Substitution: The transition from XP phenolic to glass epoxy substrate represents an allowable material variation. Both substrates satisfy identical compliance requirements and maintain the specified dimensional tolerances and electrical properties required for turret board applications.

Frequently Asked Questions (FAQ)

Q: Can the Keystone Electronics 15310 directly replace the 15110 in existing designs?

A: Yes. The 15310 is dimensionally and electrically equivalent to the 15110 across all critical parameters. The board maintains identical position count (66), pitch (0.375"), row configuration (2 rows at 0.750" spacing), and overall dimensions (13.125" x 1.188" x 0.093"). Both parts use brass contacts with tin finish and meet ROHS3 compliance.

Q: What is the difference between the XP phenolic material in the 15110 and the glass epoxy material in the 15310?

A: Both materials are substrate options for turret boards that meet identical electrical and mechanical specifications. Glass epoxy offers enhanced moisture resistance and dimensional stability compared to XP phenolic, while maintaining the same RoHS3 compliance and MSL rating. The material change does not affect electrical performance or mechanical compatibility.

Q: Are there any compatibility concerns when substituting the 15310 for the 15110?

A: No compatibility concerns exist. The 15310 maintains identical mounting hole diameter (0.120"), board dimensions, and turret terminal specifications. Direct mechanical and electrical substitution is supported.

Q: Why is the 15110 listed as obsolete?

A: The 15110 has been discontinued by Keystone Electronics. The 15310 represents the active product line continuation with equivalent specifications and improved material composition.

Q: What is the inventory status of these parts?

A: The 15110 has 995 pieces available as new original stock. The 15310 has 831 pieces available as new original stock. Both parts are currently in inventory.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 15110 and 15310 are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting current environmental and regulatory requirements.
