• Connector Series & Type: Must be DF22 series rectangular header connector
• Position Count & Pitch: Must maintain 3 positions at 0.312" (7.92mm) mating pitch
• Mounting Configuration: Through-hole solder termination with shrouded 4-wall design
• Electrical Ratings: Voltage rating of 1000V minimum; current rating compatibility
• Material Compliance: UL94 V-0 flammability rating; RoHS compliance status
• Contact Configuration: Male pin contacts with copper alloy material

The substitute parts identified below meet these core substitution criteria while offering improvements in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

DF22-3P-7.92DSA(23): This substitute maintains active product status and provides expanded operating temperature range (-55°C to 85°C versus -35°C to 85°C). Gold contact finish offers enhanced corrosion resistance compared to the tin-copper finish of the original part. Glass-filled nylon insulation material provides improved mechanical properties. RoHS compliance is maintained. This variant is suitable for applications requiring extended low-temperature performance.

DF22-3P-7.92DSA(53): This substitute is the primary recommended equivalent, offering active product status with ROHS3 compliance certification and REACH unaffected status. Gold contact finish with specified thickness (8.00µin / 0.203µm) provides superior contact reliability. Extended operating temperature range (-55°C to 85°C) accommodates broader environmental conditions. Additional board lock feature enhances mechanical retention. Beige insulation color matches the original part specification. This variant represents the most direct functional replacement with enhanced compliance documentation.

Both substitutes maintain electrical and mechanical compatibility with the original DF22-3P-7.92DSA(05) specification while offering improved product lifecycle status and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can DF22-3P-7.92DSA(23) and DF22-3P-7.92DSA(53) be used interchangeably with DF22-3P-7.92DSA(05)?

A: Both substitutes maintain identical connector pitch (0.312" / 7.92mm), position count (3), mounting type (through-hole), and core electrical ratings (1000V). Physical dimensions and contact post lengths are equivalent. The primary differences are contact finish material (gold versus tin-copper) and operating temperature range. Interchangeability depends on specific application requirements regarding contact finish and temperature extremes.

Q: What is the significance of the contact finish difference between tin-copper and gold?

A: Contact finish affects corrosion resistance and contact reliability. Gold finish provides superior corrosion resistance and lower contact resistance over extended service life, particularly in humid or corrosive environments. Tin-copper finish is suitable for standard indoor applications. Gold-finished substitutes are recommended for critical applications or extended storage periods.

Q: Why does DF22-3P-7.92DSA(53) include a board lock feature while the original does not?

A: The board lock feature provides additional mechanical retention during assembly and operation. This enhancement does not affect electrical compatibility but improves connector stability on the PCB. Applications requiring enhanced mechanical security benefit from this feature.

Q: Are there packaging differences between these parts?

A: DF22-3P-7.92DSA(05) and DF22-3P-7.92DSA(23) packaging is not specified. DF22-3P-7.92DSA(53) is supplied in bag packaging. Packaging differences do not affect connector functionality or compatibility.

Q: What does ROHS3 compliance mean compared to RoHS compliance?

A: ROHS3 represents compliance with the latest RoHS Directive revision, incorporating additional restricted substance requirements. ROHS3 compliance ensures adherence to current regulatory standards and is preferred for new designs and long-term procurement strategies.
