Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF5-1822SCF(51) is determined by strict equivalence across the following critical parameters:

• Series designation (DF5)
• Socket contact type
• Crimp termination method
• Wire gauge specification (18-22 AWG)
• Tin contact finish
• Base product number (DF5-1822)
• Moisture sensitivity level (MSL 1)

The direct substitute DF5-1822SCF maintains identical electrical and mechanical specifications while offering active product status and improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The DF5-1822SCF serves as the direct functional equivalent to the obsolete DF5-1822SCF(51). Both components share identical electrical and mechanical specifications within the DF5 rectangular connector series. The substitute part offers the following advantages:

• RoHS compliance certification provides regulatory alignment for applications subject to hazardous substance restrictions
• Significantly higher inventory levels (10119 units versus 877 units) support production scheduling and supply chain reliability
• Identical MSL rating, contact specifications, and termination method ensure drop-in compatibility

Selection of the DF5-1822SCF is appropriate for all applications currently specified with the DF5-1822SCF(51).

Frequently Asked Questions (FAQ)

Q: Are DF5-1822SCF(51) and DF5-1822SCF electrically and mechanically identical?

A: Yes. Both components are socket contacts within the DF5 series, rated for 18-22 AWG wire gauges with crimp termination and tin finish. Electrical and mechanical specifications are equivalent.

Q: What is the significance of the "(51)" designation in DF5-1822SCF(51)?

A: The "(51)" suffix typically indicates a specific packaging or manufacturing variant. The base product number DF5-1822 and core specifications remain unchanged. The substitute DF5-1822SCF provides identical functionality.

Q: Does the packaging difference affect compatibility?

A: Packaging format (Cut Tape versus unspecified) does not affect component performance or electrical characteristics. Packaging selection is determined by assembly process requirements and inventory management practices.

Q: Is RoHS compliance required for my application?

A: RoHS compliance is a regulatory requirement for products sold in specific markets. The substitute DF5-1822SCF carries RoHS Compliant certification, while the main part status is not specified. Verify regulatory requirements for your end application.

Q: Can I use DF5-1822SCF in existing designs specified for DF5-1822SCF(51)?

A: Yes. Identical specifications across wire gauge, contact termination, finish, and MSL rating support direct substitution without design modification.
