Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF1EC-12P-2.5DSA is determined by strict equivalence across the following electrical and mechanical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (12)
• Pitch specification (2.5mm)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Current rating (3A)
• Operating temperature range (-35°C ~ 85°C)
• Contact material and finish (Brass with Tin plating)
• Insulation material (Polyamide/Nylon)

The substitute part DF1EC-12P-2.5DSA(05) maintains identical electrical and mechanical specifications while offering active product status and improved compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The DF1EC-12P-2.5DSA(05) is the direct equivalent substitute for the obsolete DF1EC-12P-2.5DSA. Both parts are manufactured by Hirose Electric Co Ltd within the DF1E series and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction between the two parts is product status and regulatory compliance. The DF1EC-12P-2.5DSA(05) carries active product status, ensuring ongoing manufacturer support and availability. Additionally, the substitute part achieves RoHS compliance, whereas the original part is RoHS non-compliant. Both parts maintain identical moisture sensitivity levels and export classifications.

For new designs or component replenishment, the DF1EC-12P-2.5DSA(05) is the appropriate selection. The parts are mechanically and electrically interchangeable with no design modifications required.

Frequently Asked Questions (FAQ)

Q: Are the DF1EC-12P-2.5DSA and DF1EC-12P-2.5DSA(05) mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including pitch, number of positions, mounting type, shrouding configuration, and contact dimensions. No PCB layout or connector housing modifications are required for substitution.

Q: What is the significance of the "(05)" designation in the substitute part number?

A: The "(05)" suffix indicates a revision or variant designation assigned by Hirose Electric Co Ltd. In this case, it denotes the active production version of the DF1E series 12-position 2.5mm pitch header with improved compliance characteristics.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical current ratings, voltage specifications, and operating temperature ranges.

Q: Can the DF1EC-12P-2.5DSA(05) be used in existing assemblies designed for the original part?

A: Yes. The substitute part maintains full compatibility with existing PCB designs, mating connectors, and cable assemblies. No design changes are necessary.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
