D9724-01 Equivalent & Substitute Parts

Part Overview

The D9724-01 is a 24-position DIP/DIL header connector with male pins, manufactured by Harwin Inc. This through-hole solder-terminated component features a 0.100" (2.54mm) pitch and 0.400" (10.16mm) row spacing in a 2-row configuration. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D9724-01 is based on maintaining electrical and mechanical compatibility through matching critical parameters: connector type (DIP/DIL header), position count (24), pitch (0.100"), row configuration (2 rows with 0.400" spacing), mounting method (through-hole), and termination type (solder). The primary distinction between the main part and its substitute lies in contact geometry: the D9724-01 uses male pins, while the substitute employs posts. Both configurations are mechanically and electrically compatible within DIP/DIL header applications, as they accommodate the same mating interface and PCB footprint. Contact finish composition (tin versus tin-lead) represents a secondary variation that does not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

The 150-90-424-00-001000 (Mill-Max Manufacturing Corp.) serves as the direct functional equivalent to the obsolete D9724-01. Both components maintain identical electrical and mechanical specifications across all critical parameters: 24-position DIP/DIL header configuration, 0.100" pitch, 2-row layout with 0.400" row spacing, through-hole mounting, and solder termination. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity. Both parts share identical RoHS non-compliance and MSL ratings, maintaining consistency in compliance posture. The contact finish difference (tin versus tin-lead) and increased finish thickness on the substitute part do not compromise functional compatibility. Selection of the Mill-Max part eliminates obsolescence risk while preserving full mechanical and electrical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the 150-90-424-00-001000 directly replace the D9724-01 in existing designs?

A: Yes. Both parts maintain identical pitch (0.100"), position count (24), row configuration (2 rows, 0.400" spacing), mounting type (through-hole), and termination method (solder). The contact geometry difference (male pin versus post) does not affect PCB footprint or mating interface compatibility.

Q: What is the significance of the contact type difference between male pin and post?

A: Both male pins and posts are standard contact geometries for DIP/DIL header connectors. The functional difference is minimal in applications where the connector mates with standard DIP/DIL sockets or receptacles. Both configurations provide equivalent electrical performance and mechanical retention.

Q: Does the tin-lead finish on the substitute part affect compatibility?

A: No. The contact finish composition does not impact electrical or mechanical compatibility. Both tin and tin-lead finishes are suitable for solder termination and provide equivalent contact resistance and reliability characteristics.

Q: Why is the D9724-01 listed as obsolete?

A: Obsolescence status indicates the part is no longer in active production. The Mill-Max 150-90-424-00-001000 provides continued access to equivalent functionality through an active product line.

Q: Are there any compliance differences between the two parts?

A: Both parts share identical RoHS non-compliance and REACH unaffected status. Moisture sensitivity levels are identical (MSL 1 - Unlimited). No compliance divergence exists between the main part and substitute.

Q: What packaging format is available for the substitute part?

A: The 150-90-424-00-001000 is supplied in tube packaging, suitable for automated assembly and manual handling applications.
