D0822-01 IC DIP Socket 22-Position Equivalent & Substitute Parts

Part Overview

The Harwin D0822-01 is a 22-position DIP socket designed for through-hole mounting applications requiring gold-plated mating contacts and wire wrap termination. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The D0822-01 provides reliable IC interconnection with beryllium copper mating contacts and brass wire wrap posts, suitable for applications operating across -55°C to 125°C temperature ranges.

Substitute Part Grouping Explanation

Substitution for the D0822-01 is determined by strict equivalence across the following critical parameters:

22-position DIP configuration with 0.4" (10.16mm) row spacing
0.100" (2.54mm) pitch for both mating and post contacts
Gold-plated beryllium copper mating contacts
Wire wrap termination on brass posts
Through-hole mounting
1 A current rating and 10mOhm contact resistance
Operating temperature range of -55°C to 125°C
UL94 V-0 flammability rating
Housing material: Polycyclohexylenedimethylene Terephthalate (PCT), Polyester, Glass Filled

The Preci-Dip 122-87-422-41-001101 meets all critical electrical and mechanical parameters required for direct substitution. Variations in termination post length and contact finish thickness do not affect functional compatibility within the specified application envelope.

Engineering Selection Recommendations

The Preci-Dip 122-87-422-41-001101 is the direct functional equivalent for the obsolete Harwin D0822-01. Selection of the Preci-Dip substitute provides the following advantages:

Active product status ensures ongoing availability and supply chain continuity
ROHS3 compliance satisfies current regulatory requirements, whereas the D0822-01 is RoHS non-compliant
Identical electrical performance across all critical parameters: contact resistance, current rating, and operating temperature range
Mechanical compatibility confirmed through matching pin count, pitch, row spacing, and termination type
Both components carry UL94 V-0 flammability certification and REACH unaffected status

The Preci-Dip component is suitable for new designs and replacement applications where the D0822-01 is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the Preci-Dip 122-87-422-41-001101 be used as a direct replacement for the Harwin D0822-01?

A: Yes. Both components share identical pin count (22 positions), row spacing (0.4"), pitch (0.100"), contact materials (beryllium copper mating, brass posts), and electrical ratings (1 A, 10mOhm contact resistance). The components are mechanically and electrically interchangeable.

Q: What is the difference in termination post length between the two parts?

A: The D0822-01 has a termination post length of 0.510" (12.95mm), while the Preci-Dip substitute has 0.370" (9.40mm). This difference does not affect functional compatibility for standard wire wrap applications, provided PCB design accommodates the shorter post length.

Q: Does the Preci-Dip substitute meet current regulatory requirements?

A: Yes. The 122-87-422-41-001101 is ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The obsolete D0822-01 is RoHS non-compliant.

Q: Are the contact finish specifications equivalent?

A: Both components feature gold-plated mating contacts suitable for reliable IC interconnection. The D0822-01 specifies 10.0µin (0.25µm) gold thickness, while the Preci-Dip substitute specifies flash gold plating. Both finishes provide equivalent corrosion resistance and electrical performance for the specified application.

Q: What is the inventory status of each component?

A: The Harwin D0822-01 has 775 pieces in stock as new original inventory. The Preci-Dip 122-87-422-41-001101 has 1029 pieces in stock as new original inventory.
