D0824-01 IC DIP Socket 24-Position Equivalent & Substitute Parts

Part Overview

The Harwin D0824-01 is a 24-position DIP socket designed for IC and transistor applications with 0.6" row spacing and gold-plated mating contacts. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and procurement continuity. The D0824-01 remains functionally viable but is no longer in active production, necessitating evaluation of alternative sources that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the D0824-01 is determined by strict alignment with the following critical parameters:

24-position configuration (2 x 12 arrangement)
0.6" (15.24mm) row spacing
0.100" (2.54mm) mating pitch
Gold contact finish on mating surfaces
Beryllium copper mating contact material
Through-hole mounting with wire wrap termination
Operating temperature range of -55°C to 125°C
1 A current rating capability
10mOhm contact resistance specification
UL94 V-0 flammability rating

The Preci-Dip 122-87-624-41-001101 meets all mandatory electrical and mechanical parameters required for direct substitution. Variations in termination post length and contact finish thickness on post surfaces do not affect functional compatibility in wire wrap applications.

Engineering Selection Recommendations

The Preci-Dip 122-87-624-41-001101 is a direct functional equivalent to the Harwin D0824-01. Selection between these parts should be based on the following factors:

Product Status: The D0824-01 is obsolete with limited remaining inventory (776 pcs). The Preci-Dip 122-87-624-41-001101 is active production with higher inventory availability (1163 pcs), ensuring long-term procurement viability.

Regulatory Compliance: The Preci-Dip part is ROHS3 compliant, whereas the Harwin part is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the Preci-Dip substitute is the appropriate selection.

Physical Dimensions: The Preci-Dip part features a shorter termination post length (0.370" vs. 0.510"), which may require PCB design verification to confirm wire wrap clearance and solder joint formation. Both parts maintain identical mating contact geometry and row spacing.

Contact Finish Specification: The Preci-Dip part specifies flash gold plating on mating contacts versus the Harwin specification of 10.0µin thickness. Both finishes provide equivalent electrical performance and corrosion resistance for wire wrap applications.

Frequently Asked Questions (FAQ)

Q: Can the Preci-Dip 122-87-624-41-001101 be used as a direct replacement for the Harwin D0824-01 in existing designs?

A: Yes. Both parts share identical electrical specifications, mating contact geometry, row spacing, pitch, and current rating. The primary design consideration is the difference in termination post length (0.370" vs. 0.510"), which must be verified against PCB layout and wire wrap tool specifications.

Q: What is the significance of the difference in contact finish thickness?

A: The Harwin part specifies 10.0µin (0.25µm) gold plating, while the Preci-Dip part specifies flash plating. Both finishes provide adequate corrosion resistance and electrical conductivity for wire wrap termination. Flash plating is a thinner, more economical specification that meets functional requirements without performance degradation.

Q: Does the RoHS compliance difference affect substitution eligibility?

A: RoHS compliance is a regulatory and procurement consideration, not an electrical or mechanical compatibility factor. If your application or customer requirements mandate RoHS compliance, the Preci-Dip 122-87-624-41-001101 is the appropriate selection. If RoHS compliance is not required, both parts are functionally equivalent.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts are rated for -55°C to 125°C operating temperature, 1 A current capacity, and 10mOhm contact resistance. Thermal and electrical performance are identical.

Q: What should be verified before implementing the Preci-Dip substitute in production?

A: Confirm that the shorter termination post length (0.370" vs. 0.510") accommodates your PCB thickness and wire wrap tool specifications. Verify that flash gold plating meets your application's corrosion resistance requirements. Confirm RoHS compliance status aligns with your regulatory obligations.
