Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DF22L-2P-7.92DSA(05) are qualified based on the following critical parameters that must remain consistent:

• Connector Type & Series: Header connectors within the DF22 family
• Position Count & Pitch: 2 positions at 0.312" (7.92mm) mating pitch
• Mounting Configuration: Through-hole with solder termination
• Shrouding Design: Shrouded 4-wall construction
• Electrical Ratings: Voltage rating of 1000V and compatible current handling
• Material Compliance: UL94 V-0 flammability rating and RoHS compliance

The substitute parts identified—DF22L-2P-7.92DSA(23) and DF22L-2P-7.92DSA(53)—maintain these core parameters while offering active product status and enhanced specifications in certain areas such as contact finish and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full compatibility with the electrical and mechanical specifications of the DF22L-2P-7.92DSA(05). Selection between the two active alternatives should be based on the following factors:

DF22L-2P-7.92DSA(23) is suitable for applications requiring gold-plated mating contacts with extended lower operating temperature capability (-55°C minimum). The glass-filled nylon insulation material provides enhanced mechanical properties. This variant is recommended for general-purpose applications where the extended temperature range provides design margin.

DF22L-2P-7.92DSA(53) offers gold-plated contacts on both mating and post surfaces with additional board lock features beyond the standard board guide. This variant includes REACH compliance documentation and ROHS3 certification, making it the preferred choice for applications with stringent environmental and regulatory requirements. The presence of both board guide and board lock features provides enhanced mechanical retention.

Both substitute parts carry active product status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can DF22L-2P-7.92DSA(23) and DF22L-2P-7.92DSA(53) be used interchangeably with DF22L-2P-7.92DSA(05)?

A: Both substitute parts maintain the same connector type, position count, pitch, mounting configuration, and shrouding design. The primary differences are contact finish material (gold versus tin), operating temperature range, and fastening features. Interchangeability depends on application-specific requirements for contact finish, temperature range, and mechanical retention features.

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

A: The original part features tin-plated mating contacts, while both substitutes use gold plating. Gold provides superior corrosion resistance and lower contact resistance, particularly beneficial in high-reliability applications. This represents an improvement over the original specification.

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 extended lower temperature capability is fully backward compatible and provides additional design margin for applications operating in cold environments.

Q: What is the difference between DF22L-2P-7.92DSA(53) board guide and board lock features?

A: The board guide feature provides alignment during connector mating. The board lock feature adds mechanical retention to prevent accidental disconnection. The original part includes board guide only; the substitute includes both features, providing enhanced mechanical security.

Q: Are there packaging differences between the substitute parts?

A: DF22L-2P-7.92DSA(53) is supplied in bag packaging, while DF22L-2P-7.92DSA(23) packaging is not specified. This may affect handling and storage procedures but does not impact electrical or mechanical performance.

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

A: For new designs, DF22L-2P-7.92DSA(53) is recommended due to active product status, enhanced compliance certifications (ROHS3 and REACH), and additional mechanical retention features. This ensures maximum long-term availability and regulatory compliance.
