Substitute Part Grouping Explanation

Substitution eligibility for the DF22-2P-7.92DSA(05) is determined by the following critical parameters:

Connector geometry: 2-position header, 0.312" (7.92mm) pitch, shrouded 4-wall configuration
Electrical ratings: 1000V voltage rating, current capacity suitable for the application
Mounting interface: Through-hole termination with solder connection
Material compliance: UL94 V-0 flammability rating, RoHS compliance status
Mechanical compatibility: Insulation height 0.713" (18.10mm), contact material (Copper Alloy), fastening type (Latch Holder)

Two active alternatives meet these substitution criteria within the DF22 series: DF22-2P-7.92DSA(23) and DF22-2P-7.92DSA(53). Both maintain the core connector geometry, electrical ratings, and mounting characteristics required for direct functional replacement.

Engineering Selection Recommendations

Both DF22-2P-7.92DSA(23) and DF22-2P-7.92DSA(53) are active products suitable for replacing the obsolete DF22-2P-7.92DSA(05).

DF22-2P-7.92DSA(23) provides an active alternative with extended operating temperature range (-55°C to 85°C versus -35°C to 85°C) and gold contact finish. The insulation material includes glass-filled polyamide, offering enhanced mechanical properties. Current rating is specified as varying by wire gauge. RoHS compliance is maintained.

DF22-2P-7.92DSA(53) maintains the original square contact shape and beige insulation color of the DF22-2P-7.92DSA(05), with extended operating temperature range (-55°C to 85°C) and gold contact finish on both mating and post surfaces. This variant includes board lock features in addition to board guide. ROHS3 compliance is certified. Current rating is specified as varying by wire gauge.

Selection between these alternatives depends on specific application requirements regarding contact finish, insulation material composition, and feature set (board lock capability in the DF22-2P-7.92DSA(53)).

Frequently Asked Questions (FAQ)

Q: Can DF22-2P-7.92DSA(23) and DF22-2P-7.92DSA(53) be used interchangeably with DF22-2P-7.92DSA(05)?

A: Both alternatives maintain the same 2-position, 0.312" (7.92mm) pitch header configuration, through-hole mounting, and 1000V electrical rating. Mechanical compatibility is established through identical insulation height, shrouding geometry, and fastening type. Substitution is electrically and mechanically valid.

Q: What is the difference in contact finish between the three parts?

A: The DF22-2P-7.92DSA(05) features tin-copper contact finish (39.4µin/1.00µm thickness). Both DF22-2P-7.92DSA(23) and DF22-2P-7.92DSA(53) use gold contact finish, which provides enhanced corrosion resistance and contact reliability. The DF22-2P-7.92DSA(53) specifies gold finish on both mating and post surfaces (8.00µin/0.203µm thickness).

Q: How do the operating temperature ranges differ?

A: The DF22-2P-7.92DSA(05) operates from -35°C to 85°C. Both substitute parts extend the lower temperature limit to -55°C, providing a wider operating envelope suitable for applications requiring enhanced cold-temperature performance.

Q: What is the significance of the board lock feature in DF22-2P-7.92DSA(53)?

A: The DF22-2P-7.92DSA(53) includes both board guide and board lock features, compared to board guide only in DF22-2P-7.92DSA(23). Board lock provides mechanical retention during mating operations, reducing the risk of accidental disconnection in vibration-prone environments.

Q: Are there packaging differences between the substitute parts?

A: DF22-2P-7.92DSA(05) and DF22-2P-7.92DSA(23) do not specify packaging. DF22-2P-7.92DSA(53) is supplied in bag packaging.

Q: How do the insulation materials compare?

A: DF22-2P-7.92DSA(05) and DF22-2P-7.92DSA(53) use polyamide (PA) nylon insulation. DF22-2P-7.92DSA(23) specifies polyamide (PA) nylon with glass filling, which enhances mechanical strength and dimensional stability.
