Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF22-2P-7.92DS(36) is determined by the following critical parameters:

• Connector Series & Pitch: Both parts must belong to the EnerBee™ DF22 series with identical 0.312" (7.92mm) mating pitch to ensure mechanical and electrical compatibility
• Position Count & Configuration: 2-position header with identical shrouding (Shrouded - 4 Wall) and board guide features
• Mounting & Termination: Through-hole, right-angle mounting with solder termination
• Electrical Ratings: Voltage rating of 1000V and current handling capability
• Compliance & Material Standards: UL94 V-0 flammability rating and RoHS compliance

The substitute part DF22-2P-7.92DS(53) maintains all these core parameters while offering enhanced specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

The DF22-2P-7.92DS(53) is the direct substitute for the obsolete DF22-2P-7.92DS(36). Both parts maintain identical mechanical and electrical core specifications, ensuring drop-in compatibility for board-to-cable/wire applications.

Key advantages of the substitute part:

• Active Product Status: DF22-2P-7.92DS(53) is currently in active production, ensuring long-term availability and supply chain continuity
• Enhanced Temperature Range: Operating temperature extends to -55°C, providing broader environmental capability compared to the -35°C lower limit of the original part
• Gold Contact Finish: Specified gold plating on both mating and post contacts improves corrosion resistance and contact reliability
• Updated Compliance: ROHS3 Compliant status reflects current regulatory requirements
• REACH Unaffected Status: Confirms compliance with chemical substance regulations

Both parts carry UL94 V-0 flammability rating, unlimited moisture sensitivity level (MSL 1), and identical mechanical dimensions, making the substitute suitable for direct replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can DF22-2P-7.92DS(53) be used as a direct replacement for DF22-2P-7.92DS(36)?

A: Yes. Both parts share identical connector series, pitch, position count, mounting type, and core electrical ratings. The substitute maintains full mechanical and electrical compatibility for board-to-cable/wire applications.

Q: What are the differences between these two parts?

A: The primary differences are product status (obsolete vs. active), operating temperature range (-35°C to 85°C vs. -55°C to 85°C), contact finish specification (unspecified vs. gold plating), and compliance certifications (RoHS vs. ROHS3). The substitute offers enhanced environmental performance and improved contact reliability through gold plating.

Q: Are the physical dimensions identical?

A: Yes. Contact length (mating and post), insulation height, and overall mechanical envelope are identical between both parts. The 0.312" (7.92mm) pitch and 2-position configuration remain unchanged.

Q: What is the significance of the gold contact finish on the substitute part?

A: Gold plating on both mating and post contacts provides enhanced corrosion resistance and improved electrical contact reliability compared to unspecified finishes. This is particularly beneficial in applications subject to environmental exposure or extended service life.

Q: Does the extended temperature range of DF22-2P-7.92DS(53) affect compatibility?

A: No. The extended lower operating limit (-55°C vs. -35°C) represents an enhancement that does not compromise compatibility with designs originally specified for the narrower range. Applications requiring only -35°C to 85°C operation remain fully supported.

Q: Are there packaging differences between these parts?

A: The original part packaging is not specified. The substitute is supplied in bag packaging. Verify packaging requirements for your specific procurement and assembly processes.

Q: What compliance certifications apply to both parts?

A: Both parts carry UL94 V-0 flammability rating and unlimited moisture sensitivity level (MSL 1). The substitute additionally specifies ROHS3 Compliance and REACH Unaffected status, reflecting current regulatory standards.
