Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1B-R24A is determined by strict alignment of the following critical parameters:

• Series Compatibility: Both parts must belong to the DF1B series
• Contact Type: Socket configuration required
• Termination Method: IDC termination mandatory
• Wire Gauge: 24 AWG specification
• Contact Finish: Gold plating required
• Electrical Performance: Equivalent contact resistance and signal integrity characteristics

The substitute part DF1B-R24A(06) meets all these criteria, differing only in packaging configuration and product lifecycle status. This substitution maintains full functional and mechanical compatibility within the DF1B rectangular connector ecosystem.

Parameter Comparison

Engineering Selection Recommendations

The DF1B-R24A(06) serves as the direct substitute for the obsolete DF1B-R24A. Both components maintain identical electrical and mechanical specifications for socket contact configuration, IDC termination, 24 AWG wire gauge, and gold contact finish.

The primary distinction lies in regulatory compliance: DF1B-R24A(06) achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations, DF1B-R24A(06) is the appropriate selection. The Last Time Buy status of DF1B-R24A(06) indicates limited future availability, necessitating timely procurement for sustained supply chain requirements.

Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification and REACH Unaffected status, ensuring compatibility with standard storage and handling protocols.

Frequently Asked Questions (FAQ)

Q: Can DF1B-R24A(06) be used as a direct replacement for DF1B-R24A?

A: Yes. Both components are socket contacts within the DF1B series with identical IDC termination, 24 AWG wire gauge, and gold contact finish. Mechanical and electrical compatibility is maintained.

Q: What is the significance of the "(06)" designation in DF1B-R24A(06)?

A: The "(06)" suffix indicates a specific packaging configuration (Bulk) and represents a variant within the DF1B-R24A product line. The core contact specifications remain unchanged.

Q: Why is RoHS compliance status different between the two parts?

A: DF1B-R24A is RoHS non-compliant, while DF1B-R24A(06) achieves ROHS3 compliance. This reflects manufacturing process updates and material composition changes. Selection depends on regulatory requirements applicable to the end application.

Q: Are there any differences in moisture sensitivity or storage requirements?

A: No. Both parts maintain MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.

Q: What does "Last Time Buy" status mean for DF1B-R24A(06)?

A: Last Time Buy indicates this is the final production run before discontinuation. Procurement should be planned accordingly to ensure adequate inventory for future requirements.
