28-536-11 PLCC ZIF Socket Equivalent & Substitute Parts

Part Overview

The Aries Electronics 28-536-11 is a 28-position PLCC Zero Insertion Force (ZIF) socket with gold-plated contacts designed for through-hole mounting applications. This component provides secure, repeatable connections for 28-pin PLCC integrated circuits in development, testing, and production environments. The ZIF mechanism enables tool-free insertion and extraction of components, reducing mechanical stress on both the socket and the device leads.

Finding equivalent and substitute parts is necessary when addressing inventory constraints, managing supply chain disruptions, or matching specific application requirements for socket configuration and mounting style.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for PLCC ZIF sockets is determined by the following critical parameters:

• Socket Type: Must be PLCC ZIF configuration to maintain mechanical and electrical compatibility
• Contact Material: Gold plating ensures consistent electrical performance and corrosion resistance
• Manufacturer: Aries Electronics maintains consistent design standards across the 536 and 537 series
• Mounting Style: Through-hole and surface-mount variants serve different PCB assembly requirements and are not interchangeable without board redesign

The identified substitute part (84-537-21) shares the same manufacturer, socket type, and contact material. However, it differs in position count (84 vs. 28) and mounting configuration (surface mount vs. through hole), making it suitable only for applications requiring higher pin density and surface-mount assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Selection between the main part and substitute should be based on application-specific requirements:

Use 28-536-11 when:

• PCB design specifies 28-position PLCC socket configuration
• Through-hole mounting is required for the assembly process
• Existing board layout and component placement are fixed

Use 84-537-21 when:

• Application requires 84-position PLCC socket capacity
• Surface-mount assembly process is specified
• PCB design accommodates the larger footprint and surface-mount pad configuration

Both parts are new original stock from Aries Electronics and maintain equivalent electrical performance within their respective position and mounting specifications.

Frequently Asked Questions (FAQ)

Q: Can 84-537-21 be used as a direct replacement for 28-536-11?

A: No. While both are Aries Electronics PLCC ZIF sockets with gold contacts, they differ in position count (84 vs. 28) and mounting style (surface mount vs. through hole). Direct substitution requires PCB redesign.

Q: What does ZIF (Zero Insertion Force) mean for socket selection?

A: ZIF sockets feature a mechanical lever that opens and closes the contact arms, allowing components to be inserted and removed without applying force. Both the main part and substitute incorporate this mechanism.

Q: Are the gold contacts on both parts equivalent?

A: Yes. Both 28-536-11 and 84-537-21 use gold-plated contacts, providing equivalent electrical conductivity and corrosion resistance for their respective applications.

Q: What is the primary difference between these two socket options?

A: The main differences are position count (28 vs. 84 pins) and mounting configuration (through hole vs. surface mount). These differences make them suitable for different PCB designs and assembly processes.

Q: Can through-hole and surface-mount sockets be used interchangeably?

A: No. Through-hole sockets require drilled holes and are soldered from the board underside. Surface-mount sockets are soldered directly to pad patterns on the board surface. PCB design must specify the mounting style.
