DF1B-24PRB Equivalent & Substitute Parts

Part Overview

The DF1B-24PRB is a rectangular connector pin contact manufactured by Hirose Electric Co Ltd, designed for 24 AWG IDC (Insulation Displacement Contact) applications with gold plating. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing procurement and system maintenance. The DF1B series provides standardized rectangular connector solutions for industrial and commercial applications requiring reliable pin termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1B-24PRB is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the DF1B series to ensure mechanical and electrical interchangeability within the connector system.
• Contact Configuration: Pin contact type must be maintained for socket compatibility.
• Termination Method: IDC termination is required for wire gauge compatibility and insertion force specifications.
• Wire Gauge: 24 AWG specification must be preserved to ensure proper contact pressure and electrical performance.
• Contact Finish: While the primary part uses gold plating, tin-plated alternatives within the same series and termination specification are functionally equivalent for most applications, with differences limited to corrosion resistance and contact resistance characteristics.

The DF1B-24PR substitute part meets all critical substitution criteria while offering improved availability as a Last Time Buy component.

Parameter Comparison

Engineering Selection Recommendations

The DF1B-24PR is the designated substitute for the obsolete DF1B-24PRB. Both components share identical mechanical and electrical specifications within the DF1B series, including pin configuration, IDC termination method, and 24 AWG wire gauge compatibility. The primary distinction is the contact finish: DF1B-24PR uses tin plating instead of gold plating, and carries ROHS3 compliance certification.

Selection of the DF1B-24PR is appropriate for applications where the DF1B-24PRB is no longer available. The tin contact finish maintains electrical performance and contact reliability equivalent to the gold-plated original within standard operating environments. The Last Time Buy status of the DF1B-24PR indicates limited future availability; long-term procurement planning should account for this constraint.

Frequently Asked Questions (FAQ)

Q: Are DF1B-24PRB and DF1B-24PR mechanically interchangeable?

A: Yes. Both components are pin contacts within the DF1B series with identical IDC termination and 24 AWG wire gauge specifications. Mechanical fit and insertion force characteristics are equivalent.

Q: What is the functional difference between gold and tin contact finishes?

A: Contact finish affects corrosion resistance and contact resistance characteristics. Gold plating provides superior corrosion resistance in harsh environments; tin plating is suitable for standard industrial applications. Both finishes maintain electrical performance within normal operating conditions.

Q: Why is DF1B-24PR classified as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has announced end-of-life for this component. Existing inventory is available, but future production is not planned. Procurement should account for this limited availability window.

Q: Is DF1B-24PR ROHS compliant?

A: Yes, DF1B-24PR is ROHS3 compliant. This certification confirms the component meets Restriction of Hazardous Substances requirements for lead-free and restricted substance content.

Q: Can I use DF1B-24PR in applications originally designed for DF1B-24PRB?

A: Yes, within the electrical and mechanical parameters specified. The tin contact finish is functionally equivalent to gold plating for standard applications. Environmental factors such as humidity, temperature cycling, and corrosive atmospheres should be evaluated for specific use cases.
