Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3-22SCF(40) is based on strict alignment of the following critical parameters:

Substitution Criteria:

• Connector Type: Socket contact (matching pin or socket classification)
• Contact Termination Method: Crimp (matching termination technology)
• Wire Gauge Compatibility: 22 AWG (matching conductor size specification)
• Manufacturer Consistency: Hirose Electric Co Ltd (same manufacturer ecosystem)
• Moisture Sensitivity Level: MSL 1 (Unlimited) (matching environmental rating)
• Product Category: Rectangular Connectors (matching connector classification)

The substitute part DF3-22SCF meets all these criteria and represents the active production equivalent of the obsolete DF3-22SCF(40). The primary distinction is the product status transition from obsolete to active, coupled with enhanced compliance certifications and improved inventory availability.

Frequently Asked Questions (FAQ)

Q: Can DF3-22SCF be used as a direct replacement for DF3-22SCF(40)?

A: Yes. Both parts are socket contacts with identical 22 AWG wire gauge, crimp termination, and MSL 1 rating. The DF3-22SCF is the active production equivalent of the obsolete DF3-22SCF(40).

Q: What is the significance of the "(40)" designation in DF3-22SCF(40)?

A: The "(40)" suffix in the main part number is not detailed in the provided specifications. The substitute part DF3-22SCF operates under identical electrical and mechanical parameters without this designation.

Q: Are there packaging differences between the main part and substitute?

A: The main part packaging is not specified in the provided data. The substitute part DF3-22SCF is supplied in Cut Tape (CT) packaging format.

Q: Does the tin contact finish on the substitute part affect compatibility?

A: The contact finish specification is not provided for the main part DF3-22SCF(40). The substitute part DF3-22SCF specifies tin contact finish. Compatibility is determined by the matching socket type, crimp termination, and 22 AWG wire gauge.

Q: What compliance certifications apply to the substitute part?

A: The DF3-22SCF substitute carries RoHS3 compliance and REACH Unaffected status, meeting current environmental and substance restriction regulations. Both parts share identical ECCN and HTSUS classifications.

Q: Is the substitute part suitable for applications requiring MSL 1 rating?

A: Yes. The DF3-22SCF maintains MSL 1 (Unlimited) rating, identical to the main part, supporting applications with unlimited moisture sensitivity requirements.
