DF4-2428PCF Equivalent & Substitute Parts

Part Overview

The DF4-2428PCF is a board-in rectangular connector manufactured by Hirose Electric Co., Ltd., designed for crimp termination of 24-28 AWG wire gauges with tin contact finish. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement planning. The DF4 series board-in contacts remain in active production through updated variants, enabling direct functional substitution while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF4-2428PCF is determined by strict equivalence across the following critical parameters:

• Series and Base Product Number: Both main and substitute parts belong to the DF4 series with base product number DF4-2, ensuring mechanical and electrical compatibility within the connector family.
• Contact Configuration: Board-in termination type is identical, maintaining PCB mounting compatibility.
• Termination Method: Crimp termination is consistent, allowing use of existing crimping tools and processes.
• Wire Gauge Range: 24-28 AWG specification is maintained, ensuring proper contact engagement and current-carrying capacity.
• Contact Finish: Tin finish is preserved, maintaining electrical conductivity and corrosion resistance characteristics.

The identified substitute part DF4-2428PCF(05) represents an active production variant of the same base contact design, differing only in packaging format and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The DF4-2428PCF(05) is the direct functional equivalent for the obsolete DF4-2428PCF. Selection between these parts is determined by regulatory and procurement requirements:

• For RoHS-compliant applications: DF4-2428PCF(05) is the required selection, as it meets RoHS compliance standards while maintaining identical electrical and mechanical specifications.
• For legacy or non-regulated applications: Either part may be used based on inventory availability and procurement lead times.
• For new designs: DF4-2428PCF(05) is the appropriate choice due to active production status and regulatory compliance.

The transition from DF4-2428PCF to DF4-2428PCF(05) involves no changes to contact geometry, termination method, wire gauge compatibility, or electrical performance. Packaging format differs (Cut Tape for the substitute variant), which affects handling and assembly processes but not component functionality.

Frequently Asked Questions (FAQ)

Q: Can DF4-2428PCF(05) be used as a direct replacement for DF4-2428PCF in existing assemblies?

A: Yes. Both parts share identical board-in contact geometry, crimp termination specifications, 24-28 AWG wire gauge compatibility, and tin contact finish. No design modifications or re-qualification are required for functional substitution.

Q: What is the primary difference between DF4-2428PCF and DF4-2428PCF(05)?

A: The main differences are product status (obsolete vs. active) and RoHS compliance (non-compliant vs. compliant). The suffix "(05)" indicates the active production variant. Electrical and mechanical specifications are identical.

Q: Does the packaging format difference affect component performance?

A: No. Packaging format (Cut Tape for DF4-2428PCF(05)) affects handling, storage, and assembly logistics but does not impact electrical performance, contact engagement, or mechanical compatibility.

Q: Are there any wire gauge or termination method restrictions when substituting?

A: No. Both parts maintain the same 24-28 AWG wire gauge range and crimp termination method. Existing crimping tools and wire preparation procedures remain unchanged.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both DF4-2428PCF and DF4-2428PCF(05) have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
