Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF22L-3P-7.92DSA(05) is determined by the following critical parameters:

• Connector type, contact type, and number of positions (3-position male pin header)
• Pitch spacing (0.312" / 7.92mm)
• Mounting method (through-hole)
• Shrouding configuration (shrouded 4-wall)
• Voltage and current ratings (1000V, current capacity)
• Insulation material compatibility (Polyamide/Nylon)
• Flammability rating (UL94 V-0)

Two active substitute parts meet these core electrical and mechanical requirements:

DF22L-3P-7.92DSA(23) - Active status with modified contact finish and expanded operating temperature range.

DF22L-3P-7.92DSA(53) - Active status with enhanced contact finish specifications and additional board-locking features.

Parameter Comparison

Engineering Selection Recommendations

DF22L-3P-7.92DSA(23) is suitable for applications requiring active component availability with gold-plated mating contacts and extended low-temperature operation (-55°C). The glass-filled nylon insulation material provides enhanced mechanical properties. This variant maintains full electrical compatibility with the original DF22L-3P-7.92DSA(05) specification.

DF22L-3P-7.92DSA(53) is the preferred substitute for new designs and production applications. This part offers active status, ROHS3 compliance certification, gold-plated contact finishes on both mating and post surfaces, extended operating temperature range (-55°C ~ 85°C), and additional board-locking features. The square contact shape matches the original design geometry.

Both substitute parts maintain the same connector footprint, pitch spacing, shrouding configuration, and core electrical ratings as the obsolete DF22L-3P-7.92DSA(05), ensuring direct mechanical and electrical compatibility in existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can DF22L-3P-7.92DSA(23) and DF22L-3P-7.92DSA(53) be used interchangeably with DF22L-3P-7.92DSA(05)?

A: Both parts maintain the same 3-position, 0.312" pitch header configuration, through-hole mounting, and 1000V voltage rating. Mechanical and electrical compatibility is preserved. The primary differences are contact finish materials and operating temperature ranges.

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

A: The original DF22L-3P-7.92DSA(05) uses tin-plated mating contacts. Both substitutes use gold plating, which provides improved corrosion resistance and contact reliability. This is a performance enhancement that does not affect mechanical compatibility.

Q: Does the extended operating temperature range of the substitutes affect compatibility?

A: The substitutes support -55°C to 85°C operation, compared to the original -35°C to 85°C range. This expanded range is backward compatible and does not affect applications within the original temperature specification.

Q: What is the difference between DF22L-3P-7.92DSA(23) and DF22L-3P-7.92DSA(53)?

A: DF22L-3P-7.92DSA(23) features rectangular contact shapes and glass-filled nylon insulation. DF22L-3P-7.92DSA(53) features square contact shapes matching the original design, includes board-locking features, and carries ROHS3 compliance certification. Both are electrically equivalent.

Q: Are there packaging differences between these parts?

A: DF22L-3P-7.92DSA(53) is supplied in bag packaging. Packaging format does not affect electrical or mechanical performance.

Q: Which substitute should be selected for new production designs?

A: DF22L-3P-7.92DSA(53) is recommended for new designs due to active product status, ROHS3 compliance, enhanced contact finishes, and board-locking features that provide improved assembly reliability.
