Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DF3A-2P-2DSA(10) are determined by strict equivalence across the following critical parameters:

• Connector Type: Header
• Number of Positions: 2
• Pitch - Mating: 0.079" (2.00mm)
• Mounting Type: Through Hole
• Current Rating: 3A
• Operating Temperature Range: -30°C ~ 85°C
• Material Flammability Rating: UL94 V-0
• Contact Type: Male Pin
• Shrouding: Shrouded - 4 Wall
• Termination: Press-Fit, Solder
• Fastening Type: Push-Pull

The DF3A-2P-2DSA (without the (10) suffix) meets all critical electrical and mechanical parameters required for direct substitution. Variations in non-critical attributes such as insulation color do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DF3A-2P-2DSA serves as the direct substitute for the DF3A-2P-2DSA(10). Both parts maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the DF3A-2P-2DSA(10) is designated Last Time Buy, while the DF3A-2P-2DSA maintains Active status with current manufacturing availability.

For new designs or ongoing production requiring 2-position, 2.00mm pitch rectangular connectors with 3A current rating and through-hole mounting, the DF3A-2P-2DSA is the appropriate selection. Both parts satisfy RoHS and REACH compliance requirements and maintain equivalent reliability certifications.

Frequently Asked Questions (FAQ)

Q: Can DF3A-2P-2DSA be used as a direct replacement for DF3A-2P-2DSA(10)?

A: Yes. Both parts are electrically and mechanically equivalent across all functional parameters including connector type, position count, pitch, current rating, operating temperature range, and mounting configuration. The suffix (10) does not indicate a functional difference.

Q: What is the significance of the Last Time Buy status on DF3A-2P-2DSA(10)?

A: Last Time Buy status indicates that the manufacturer has discontinued production of this specific part number. Existing inventory may be available, but no future manufacturing runs are planned. The DF3A-2P-2DSA (without the suffix) remains in Active production status.

Q: Are there any compatibility concerns when substituting DF3A-2P-2DSA for DF3A-2P-2DSA(10)?

A: No compatibility concerns exist. The parts are functionally identical in all electrical and mechanical characteristics relevant to circuit board assembly and connector mating operations.

Q: What is the difference in insulation color between these parts?

A: The DF3A-2P-2DSA(10) features white insulation, while the DF3A-2P-2DSA features black insulation. This is a cosmetic distinction that does not affect electrical performance or mechanical function.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -30°C to 85°C and maintain the same UL94 V-0 flammability rating.
