D0924-42 Equivalent & Substitute Parts

Part Overview

The D0924-42 is a 24-position DIP socket manufactured by Harwin Inc., designed for through-hole mounting applications. This component features gold-plated mating contacts, wire wrap termination, and operates across the industrial temperature range of -55°C to 125°C. The part is classified as obsolete, necessitating identification of active equivalent components for ongoing design and procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D0924-42 is determined by the following critical parameters:

• Manufacturer Series Compatibility: Both parts belong to the Harwin D0 series, ensuring design consistency and mechanical interchangeability within the product family.
• Mounting Type and Termination: Through-hole mounting with wire wrap termination is maintained across substitute options.
• Electrical Specifications: Mating pitch (0.100"), contact finish (gold), current rating (1 A), and contact resistance (10mOhm) remain constant.
• Environmental Performance: Operating temperature range (-55°C ~ 125°C) and material flammability rating (UL94 V-0) are preserved.
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status are consistent across all parts.

The D0828-42 is identified as a manufacturer-recommended substitute. While the position count (28 vs. 24) and row spacing (0.6" vs. 0.3") differ, these parameters define the physical footprint rather than the functional substitution criteria. The electrical and environmental characteristics remain equivalent.

Engineering Selection Recommendations

The D0828-42 is designated as the manufacturer-recommended substitute for the obsolete D0924-42. Selection of this substitute is supported by:

• Product Status: The D0828-42 maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements.
• Electrical Equivalence: Identical current rating, contact resistance, and mating pitch specifications ensure functional compatibility in wire wrap applications.
• Environmental Specifications: Matching operating temperature range and material flammability rating preserve performance across industrial applications.

Physical footprint differences (position count and row spacing) require PCB layout modification. Design validation is necessary to confirm mechanical fit within the target application.

Frequently Asked Questions (FAQ)

Q: Can the D0828-42 be used as a direct replacement for the D0924-42 without PCB modification?

A: No. The D0828-42 has 28 positions with 0.6" row spacing, compared to the D0924-42's 24 positions with 0.3" row spacing. PCB layout modification is required to accommodate the different footprint.

Q: Are the electrical characteristics identical between these parts?

A: Yes. Both parts share identical mating pitch (0.100"), contact finish (gold), current rating (1 A), and contact resistance (10mOhm). Electrical performance in wire wrap applications is equivalent.

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

A: The D0924-42 is obsolete and no longer manufactured. The D0828-42 is in active production, ensuring availability for new designs and ongoing procurement requirements.

Q: Do both parts meet current compliance standards?

A: Yes. Both the D0924-42 and D0828-42 are ROHS3 compliant and REACH unaffected, satisfying current regulatory requirements.

Q: Are there inventory considerations for this substitution?

A: The D0828-42 has 1093 pieces in stock as new original inventory, compared to 1012 pieces for the obsolete D0924-42. Procurement should prioritize the active substitute to ensure supply continuity.
