Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF22L-4P-7.92DSA(05) is determined by the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Pitch: 4 positions at 0.312" (7.92mm) mating pitch
• Mounting & Termination: Through-hole solder termination
• Electrical Ratings: Minimum 1000V voltage rating and current capacity
• Shrouding & Fastening: Shrouded 4-wall design with latch holder fastening
• Material Compliance: UL94 V-0 flammability rating and RoHS compliance

The substitute parts DF22L-4P-7.92DSA(23) and DF22L-4P-7.92DSA(53) maintain these core parameters while offering improvements in product status and contact finish specifications.

Parameter Comparison

Engineering Selection Recommendations

DF22L-4P-7.92DSA(23) is suitable for applications requiring active product status with extended operating temperature range (-55°C to 85°C) and gold-plated contacts. This variant provides improved contact reliability through gold finish while maintaining electrical and mechanical compatibility with the original design. The glass-filled nylon insulation material offers enhanced mechanical properties.

DF22L-4P-7.92DSA(53) is the preferred substitute for new designs and ongoing production. This part maintains active product status, offers the widest operating temperature range (-55°C to 85°C), and includes both mating and post contact gold plating. The addition of board lock features and ROHS3 compliance provides enhanced design flexibility and regulatory alignment. Gold contact finish on both mating and post surfaces ensures superior contact reliability compared to the tin-plated original.

Both substitute parts maintain the core electrical specifications (1000V, UL94 V-0 compliance) and mechanical configuration (4-position, 7.92mm pitch, through-hole solder termination) required for direct functional replacement.

Frequently Asked Questions (FAQ)

Q: Can DF22L-4P-7.92DSA(23) and DF22L-4P-7.92DSA(53) be used interchangeably with the original DF22L-4P-7.92DSA(05)?

A: Both substitute parts maintain the same connector type, position count, pitch spacing, mounting method, and electrical ratings. The primary differences are contact finish (gold versus tin), operating temperature range, and additional features. Mechanical and electrical compatibility is maintained for board-to-cable/wire applications.

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

A: The original part uses tin plating (39.4µin / 1.00µm thickness), while the substitutes use gold plating. Gold provides superior corrosion resistance and contact reliability, particularly in environments with moisture or thermal cycling. Gold-plated contacts reduce contact resistance variation over the connector's operational life.

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

A: The substitutes support -55°C to 85°C versus the original -35°C to 85°C. This extended lower temperature capability does not affect compatibility with existing designs. Applications operating within the original temperature range remain fully compatible.

Q: What is the difference between DF22L-4P-7.92DSA(23) and DF22L-4P-7.92DSA(53)?

A: Both are active products with gold-plated contacts and extended temperature ranges. DF22L-4P-7.92DSA(53) includes board lock features and ROHS3 compliance certification, offering additional design security and regulatory documentation. The contact shape differs (rectangular versus square), though both maintain electrical and mechanical compatibility.

Q: Are there packaging differences between these parts?

A: DF22L-4P-7.92DSA(05) and DF22L-4P-7.92DSA(23) do not specify packaging, while DF22L-4P-7.92DSA(53) is supplied in bag packaging. This does not affect functional compatibility or performance.

Q: What compliance certifications apply to these connectors?

A: All three parts meet UL94 V-0 flammability requirements and have EAR99 export classification. DF22L-4P-7.92DSA(05) is RoHS Compliant, while DF22L-4P-7.92DSA(53) is ROHS3 Compliant and REACH Unaffected. All parts have Moisture Sensitivity Level 1 (Unlimited).
