Engineering Selection Recommendations

DF22-3P-7.92DSA(23) is suitable for applications requiring active product status with extended operating temperature range (-55°C to 85°C) and gold-plated mating contacts. This variant incorporates glass-filled nylon insulation material, providing enhanced mechanical properties. RoHS compliance is maintained.

DF22-3P-7.92DSA(53) is the preferred substitute for the obsolete DF22-3P-7.92DSA(35). This part maintains identical mechanical and electrical specifications while offering active product status, extended temperature range (-55°C to 85°C), and ROHS3 compliance. The gold-plated contact finish on both mating and post surfaces provides superior corrosion resistance compared to the tin finish of the original part. Additional features include board lock functionality in addition to board guide.

Both substitute parts maintain the critical electrical ratings (1000V, UL94 V-0), connector geometry (3-position, 7.92mm pitch, shrouded 4-wall), and through-hole mounting configuration required for direct substitution.

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(35)?

A: Both parts are mechanically and electrically compatible substitutes. The primary differences are contact finish (gold vs. tin), operating temperature range extension, and compliance certifications. Selection depends on application requirements for contact material and temperature performance.

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

A: Gold-plated contacts provide superior corrosion resistance and lower contact resistance compared to tin plating. This is particularly beneficial in high-reliability applications or environments with moisture exposure.

Q: Does the glass-filled nylon insulation in DF22-3P-7.92DSA(23) affect mechanical compatibility?

A: No. The glass-filled nylon maintains the same insulation height (0.713") and overall connector geometry. The enhancement provides improved mechanical strength and dimensional stability.

Q: What is the difference between RoHS and ROHS3 compliance?

A: ROHS3 represents the current RoHS Directive 2011/65/EU as amended. Both certifications indicate compliance with hazardous substance restrictions; ROHS3 reflects the most recent regulatory standard.

Q: Are there packaging differences between these parts?

A: DF22-3P-7.92DSA(35) and DF22-3P-7.92DSA(23) packaging is not specified. DF22-3P-7.92DSA(53) is supplied in bag packaging. Verify packaging requirements with procurement specifications.

Q: Can these connectors be used in applications requiring the full -55°C lower temperature limit?

A: DF22-3P-7.92DSA(35) is rated to -35°C minimum. Both substitute parts extend this to -55°C, enabling use in broader temperature environments. Verify application requirements before selection.
