Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Keystone Electronics 15053 is determined by strict equivalence across the following critical parameters:

• Terminal Configuration: Turret, fork-end design with identical mechanical interface
• Position Count & Pitch: 25 positions at 0.218" (5.54mm) spacing
• Board Dimensions: 7.812" L x 0.312" W x 0.062" H
• Contact Properties: Tin finish on brass material
• Mounting Interface: 0.062" (1.57mm) mounting hole diameter
• Compliance Standards: ROHS3 compliance and MSL 1 rating

The Keystone Electronics 15253 qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is the board material upgrade from PBE to Glass Epoxy and the active product status of the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The Keystone Electronics 15253 is the manufacturer-recommended substitute for the obsolete 15053 model. Both parts maintain identical electrical and mechanical specifications across all critical parameters: 25-position configuration, 0.218" pitch, fork-end turret terminals, and board dimensions.

The material upgrade from PBE to Glass Epoxy in the 15253 represents an enhancement in board durability and environmental resistance while maintaining full compliance with ROHS3 standards and MSL 1 moisture sensitivity requirements. The active product status of the 15253 ensures ongoing availability and supply chain continuity.

Selection of the 15253 as a replacement for the 15053 is supported by identical mounting interfaces, contact materials, and finish specifications, ensuring direct functional equivalence in existing circuit designs and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 15253 be used as a direct replacement for the 15053 in existing designs?

A: Yes. The 15253 maintains identical electrical and mechanical specifications across all critical parameters, including position count, pitch, board dimensions, terminal type, and contact properties. The board material change from PBE to Glass Epoxy does not affect functional compatibility.

Q: What is the significance of the board material change from PBE to Glass Epoxy?

A: Glass Epoxy provides improved mechanical strength and environmental resistance compared to PBE. This upgrade enhances long-term reliability without altering the electrical performance or mechanical interface of the component.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the 15053 and 15253 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, meeting current environmental and regulatory standards.

Q: What is the mounting hole diameter for both parts?

A: Both parts feature 0.062" (1.57mm) mounting hole diameter, ensuring identical mounting interface compatibility.

Q: Why is the 15053 classified as obsolete?

A: The 15053 has been discontinued by the manufacturer. The 15253 is the active replacement part, offering the same functional specifications with improved board material.
