Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF3-10S-2DSA(50) is determined by the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 10 positions at 0.079" (2.00mm) mating pitch
• Mounting & Termination: Through-hole solder termination with friction lock fastening
• Electrical Ratings: 3A current capacity and 30VAC voltage rating
• Environmental Specifications: Operating temperature range of -30°C to 85°C
• Material & Contact Finish: Gold-plated mating contacts with phosphor bronze contact material

The DF3-10S-2DSA(55) meets all these critical parameters and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The DF3-10S-2DSA(55) is the direct equivalent substitute for the DF3-10S-2DSA(50). All electrical, mechanical, and dimensional specifications are identical. The primary advantages of selecting the DF3-10S-2DSA(55) are:

• Product Status: Active product status ensures long-term availability and manufacturing support
• Regulatory Compliance: ROHS3 compliant, compared to the non-compliant status of the original part
• Inventory Availability: Higher stock levels (1257 Pcs vs 967 Pcs) support procurement requirements
• Packaging: Standard tube packaging for production handling

No functional or performance differences exist between these parts. The DF3-10S-2DSA(55) is suitable for direct replacement in all applications where the DF3-10S-2DSA(50) was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the DF3-10S-2DSA(55) be used as a direct replacement for the DF3-10S-2DSA(50)?

A: Yes. Both parts are identical in all electrical, mechanical, and dimensional specifications. The DF3-10S-2DSA(55) is a direct functional equivalent with no design modifications required.

Q: What is the difference between the DF3-10S-2DSA(50) and DF3-10S-2DSA(55)?

A: The primary differences are product status (active vs obsolete), RoHS compliance (ROHS3 compliant vs non-compliant), and packaging format (tube vs unspecified). All technical specifications are identical.

Q: Are there any compatibility concerns when switching from DF3-10S-2DSA(50) to DF3-10S-2DSA(55)?

A: No compatibility concerns exist. Both connectors share identical pin configurations, pitch spacing, mounting type, and electrical ratings. PCB layouts and mating connector designs require no modification.

Q: Why should I select the DF3-10S-2DSA(55) over the DF3-10S-2DSA(50)?

A: The DF3-10S-2DSA(55) offers improved regulatory compliance (ROHS3), active product status with guaranteed availability, and higher inventory levels. The obsolete status of the DF3-10S-2DSA(50) limits future procurement options.

Q: What is the mating pitch for these connectors?

A: Both connectors use a 0.079" (2.00mm) mating pitch, which determines compatibility with corresponding plug connectors in the DF3 series.

Q: Are these connectors suitable for high-temperature applications?

A: Both connectors operate within the -30°C to 85°C temperature range. Applications requiring operation outside this range require alternative connector selection.
