Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3-5S-2DSA(50) is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle, 5-position, 0.079" (2.00mm) pitch
• Electrical Ratings: 3A current, 30VAC voltage
• Mechanical Interface: Through-hole solder termination, friction lock fastening
• Contact Properties: Female socket, gold-plated mating surface, phosphor bronze material
• Environmental Specifications: -30°C ~ 85°C operating range, UL94 V-0 flammability rating
• Insulation: Polyamide (PA), Nylon construction

The DF3-5S-2DSA(55) meets all these criteria and is classified as a direct substitute within the DF3 series.

Parameter Comparison

Engineering Selection Recommendations

The DF3-5S-2DSA(55) is the direct substitute for the obsolete DF3-5S-2DSA(50). Both components share identical electrical, mechanical, and environmental specifications, ensuring functional equivalence in circuit applications.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The DF3-5S-2DSA(50) is classified as obsolete, while the DF3-5S-2DSA(55) carries Last Time Buy status, indicating continued but limited availability. Additionally, the DF3-5S-2DSA(55) achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. For new designs or ongoing production requiring regulatory alignment with current environmental standards, the DF3-5S-2DSA(55) is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can DF3-5S-2DSA(55) be used as a direct replacement for DF3-5S-2DSA(50)?

A: Yes. Both connectors are functionally equivalent across all critical parameters: 5-position configuration, 0.079" (2.00mm) pitch, 3A/30VAC ratings, through-hole solder termination, and identical mechanical dimensions. No circuit redesign or PCB modification is required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance certification. The DF3-5S-2DSA(50) is obsolete and RoHS non-compliant. The DF3-5S-2DSA(55) is Last Time Buy status and ROHS3 compliant. The packaging specification is also defined for the substitute (Tube).

Q: Are there any compatibility concerns when switching from DF3-5S-2DSA(50) to DF3-5S-2DSA(55)?

A: No compatibility concerns exist. Mechanical fit, electrical performance, and mating interface are identical. Both parts use the same DF3 series connector family with matching contact geometry and termination method.

Q: What does "Last Time Buy" status mean for DF3-5S-2DSA(55)?

A: Last Time Buy indicates that the manufacturer has announced a final production run with a defined cutoff date. After this period, the part will no longer be manufactured. Procurement planning should account for this limited availability window.

Q: Is the DF3-5S-2DSA(55) suitable for applications requiring RoHS compliance?

A: Yes. The DF3-5S-2DSA(55) is ROHS3 compliant, making it suitable for applications subject to RoHS regulations. The original DF3-5S-2DSA(50) is RoHS non-compliant and should not be used in RoHS-regulated applications.
