D0832-42 Equivalent & Substitute Parts

Part Overview

The D0832-42 is a 32-position DIP socket manufactured by Harwin Inc., designed for through-hole mounting applications requiring gold-plated mating contacts and wire wrap termination. This component features a 0.6" row spacing configuration with beryllium copper mating contacts and brass wire wrap posts. The part is currently classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design and procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D0832-42 is constrained by the following critical parameters that must remain consistent across alternative components:

• DIP Socket Configuration: 0.6" (15.24mm) row spacing with 0.100" (2.54mm) pitch
• Contact System: Gold-plated mating surface with beryllium copper material
• Termination Method: Wire wrap posts with tin finish
• Mounting: Through-hole technology
• Environmental Compliance: ROHS3 compliance and UL94 V-0 flammability rating
• Electrical Performance: 1 A current rating and 10mOhm contact resistance

The D0828-42 represents a functionally related component within the same D0 series from Harwin Inc. However, this part differs in pin count (28 positions versus 32 positions), which represents a dimensional and functional variation rather than a direct equivalent substitute. The D0828-42 maintains identical electrical characteristics, contact materials, termination methods, and environmental specifications as the D0832-42.

Parameter Comparison

Engineering Selection Recommendations

The D0828-42 shares identical electrical, thermal, and compliance characteristics with the D0832-42, including ROHS3 compliance, UL94 V-0 flammability rating, and equivalent contact performance specifications. The primary distinction is the reduction in pin count from 32 to 28 positions, which reflects a different IC package footprint requirement.

Selection of the D0828-42 as an alternative is appropriate only when the application circuit accommodates a 28-position DIP package. The D0828-42 maintains active product status with Harwin Inc., ensuring ongoing availability and supply chain continuity compared to the obsolete D0832-42.

For applications requiring the full 32-position configuration, alternative sources within the Harwin D0 series or equivalent DIP socket families from other manufacturers meeting identical electrical and environmental specifications should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the D0828-42 directly replace the D0832-42 in existing designs?

A: Direct replacement is not possible due to the difference in pin count. The D0828-42 accommodates 28-position DIP packages, while the D0832-42 is designed for 32-position packages. PCB layout and IC package compatibility must be verified before substitution.

Q: Are the electrical performance characteristics identical between these parts?

A: Yes. Both parts share identical current ratings (1 A), contact resistance (10mOhm), operating temperature range (-55°C ~ 125°C), and contact material specifications (beryllium copper mating contacts with gold plating).

Q: What is the significance of the product status difference?

A: The D0832-42 is classified as obsolete, indicating discontinued manufacturing. The D0828-42 maintains active status, ensuring continued availability from Harwin Inc. and established supply chain support.

Q: Are both parts RoHS compliant?

A: Yes. Both the D0832-42 and D0828-42 are ROHS3 compliant and carry UL94 V-0 flammability ratings, meeting current environmental and safety standards.

Q: What determines compatibility between DIP sockets and IC packages?

A: Compatibility is determined by pin count, pitch (0.100" in both cases), and row spacing (0.6" in both cases). The socket must match the physical and electrical footprint of the target IC package.
