Key Parameters

Substitute Part Grouping Explanation

The DF1B-2428SC serves as the direct substitute for the obsolete DF1B-2428SC(19). Substitution validity is determined by matching the following critical parameters:

• Socket contact type (Pin or Socket: Socket)
• Crimp termination method (Contact Termination: Crimp)
• Wire gauge specification (24-28 AWG)
• Tin contact finish (Contact Finish: Tin)
• DF1B series compatibility (Base Product Number: DF1B)
• RoHS compliance status (RoHS Compliant)
• Moisture sensitivity classification (MSL 1)

The DF1B-2428SC maintains identical specifications across all functional and compliance parameters, confirming direct substitutability.

Parameter Comparison

Engineering Selection Recommendations

The DF1B-2428SC is the appropriate selection for applications currently specified with DF1B-2428SC(19). Both components are RoHS compliant and carry identical MSL classification, ensuring regulatory and environmental compatibility. The transition from obsolete to active status does not introduce functional differences; the substitute maintains all electrical and mechanical characteristics required for direct replacement. Bulk packaging availability of the active part supports standard procurement workflows.

Frequently Asked Questions (FAQ)

Q: Can DF1B-2428SC directly replace DF1B-2428SC(19)? A: Yes. Both components share identical specifications for socket type, crimp termination, 24-28 AWG wire gauge, tin contact finish, and RoHS compliance status. Direct substitution is valid.

Q: What determines compatibility between these socket contacts? A: Compatibility is established through matching pin/socket configuration, contact termination method, wire gauge range, contact finish material, and series designation. All parameters are identical between the two parts.

Q: Are there packaging differences between the obsolete and active versions? A: The obsolete DF1B-2428SC(19) has unspecified packaging, while the active DF1B-2428SC is supplied in bulk packaging. This does not affect functional compatibility.

Q: What is the significance of MSL 1 classification? A: MSL 1 indicates unlimited shelf life with no moisture sensitivity restrictions, meaning standard storage conditions are sufficient without special handling requirements.

Q: Is RoHS compliance maintained in the substitute part? A: Yes. Both the obsolete and active versions are RoHS compliant, maintaining regulatory compliance for applications subject to RoHS requirements.
