Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1B-R24FA is determined by strict alignment with the following critical parameters:

• Contact Type: Socket configuration only
• Termination Method: IDC (Insulation Displacement Contact) technology
• Wire Gauge Compatibility: 24 AWG
• Contact Material Finish: Gold plating
• Series Compatibility: DF1B series or direct functional equivalents
• Regulatory Compliance: RoHS status and REACH classification must be documented

Based on the provided input data, the MFR recommended substitute is the DF1B-R24FA itself, indicating no alternative part number has been identified as a direct equivalent within the available component database.

Parameter Comparison

Engineering Selection Recommendations

The DF1B-R24FA is classified as obsolete. When sourcing this component, the following factors apply:

• Inventory Availability: 910 pieces of new original stock are currently available
• Regulatory Compliance: The part is RoHS non-compliant and REACH Unaffected, which may impact suitability for new designs subject to environmental regulations
• Certification Status: ECCN classification is EAR99; HTSUS code is 8536.90.4000

For applications requiring RoHS compliance or REACH compliance, alternative connector solutions from current product lines should be evaluated. The obsolete status indicates this part is no longer in active production; procurement should prioritize available inventory or identify next-generation equivalents from the manufacturer's current DF1B series offerings.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the DF1B-R24FA?

A: A substitute must match all critical parameters: socket contact type, IDC termination method, 24 AWG wire gauge compatibility, and gold contact finish. Series compatibility with DF1B or documented functional equivalence is required.

Q: Why is the DF1B-R24FA listed as its own substitute?

A: The provided data indicates no alternative part number has been identified. The MFR recommended substitute is the original part number itself, reflecting current availability of original stock.

Q: Can I use a pin contact instead of a socket contact?

A: No. The DF1B-R24FA is specifically a socket contact. Pin contacts are distinct components with different mating characteristics and are not interchangeable.

Q: Does the RoHS non-compliant status affect substitution?

A: RoHS compliance is a regulatory consideration, not a substitution criterion. However, if your application requires RoHS compliance, alternative components must be evaluated separately.

Q: What is the significance of MSL 1 (Unlimited)?

A: MSL 1 indicates unlimited shelf life with no moisture sensitivity restrictions, simplifying storage and handling requirements compared to higher MSL ratings.

Q: How does IDC termination affect compatibility?

A: IDC termination is a specific contact technology. Only components using IDC termination can substitute for this part. Other termination methods (solder, crimp) are not compatible.
