Substitute Part Grouping Explanation

Substitution eligibility for the DF22R-2P-7.92DS is determined by strict alignment of the following critical parameters:

• Connector Type & Series: Must be Header type from the EnerBee™ DF22 series
• Position Count & Pitch: Exactly 2 positions with 0.312" (7.92mm) mating pitch
• Mounting Configuration: Through hole, right-angle orientation
• Shrouding & Contact Type: Shrouded 4-wall design with male pin contacts
• Electrical Ratings: Minimum 1000V voltage rating and UL94 V-0 flammability compliance
• Termination & Fastening: Solder termination with latch holder fastening

The substitute part DF22R-2P-7.92DS(53) meets all these criteria while offering improved specifications in contact finish and product status.

Parameter Comparison

Engineering Selection Recommendations

The DF22R-2P-7.92DS(53) is the direct substitute for the obsolete DF22R-2P-7.92DS. Both parts maintain identical mechanical and electrical compatibility across all critical parameters: connector type, position count, pitch, mounting configuration, and voltage rating.

The substitute offers distinct advantages:

• Product Availability: Active product status ensures ongoing supply and support
• Regulatory Compliance: ROHS3 compliant versus non-compliant status of the main part
• Contact Finish: Gold plating provides superior corrosion resistance compared to tin-lead
• Temperature Range: Extended lower operating limit (-55°C versus -35°C) accommodates broader environmental conditions
• Packaging: Available in bag format for standard distribution

Selection of DF22R-2P-7.92DS(53) is appropriate for all applications previously using the main part number, with no design modifications required.

Frequently Asked Questions (FAQ)

Q: Are DF22R-2P-7.92DS and DF22R-2P-7.92DS(53) mechanically interchangeable?

A: Yes. Both parts share identical mounting type (through hole, right angle), shrouding configuration (4-wall), and position count (2 positions at 0.312" pitch). Physical installation is identical.

Q: What is the significance of the (53) designation in DF22R-2P-7.92DS(53)?

A: The (53) suffix indicates a variant within the same base product family, typically denoting a specific contact finish or manufacturing revision. In this case, it specifies gold-plated contacts versus the tin-lead finish of the main part.

Q: Can DF22R-2P-7.92DS(53) be used in applications rated for 1000V?

A: Yes. The substitute maintains the 1000VAC/DC voltage rating, meeting or exceeding the electrical requirements of the original part.

Q: Does the gold contact finish of DF22R-2P-7.92DS(53) affect compatibility?

A: No. Gold plating is a superior contact finish that enhances reliability and corrosion resistance. It is fully compatible with mating connectors designed for the DF22 series.

Q: Is ROHS3 compliance a requirement for substitution?

A: ROHS3 compliance of the substitute part provides regulatory advantage for new designs and markets with RoHS requirements. The original part's non-compliant status may restrict its use in certain applications or regions.

Q: What is the temperature operating range difference between the two parts?

A: The substitute extends the lower operating limit to -55°C compared to -35°C for the main part. Both maintain the same upper limit of 85°C. This provides broader environmental compatibility without affecting existing applications.
