Substitute Part Grouping Explanation

The substitute part DF1EC-3P-2.5DSA(36) is classified as a direct equivalent based on the following critical parameters that determine substitution compatibility:

• Identical connector type, contact configuration, and pitch specification (0.098" / 2.50mm)
• Matching number of positions (3) and row configuration (1 row)
• Identical mounting method (through hole solder termination)
• Equivalent electrical rating (3A current capacity)
• Identical operating temperature range (-35°C ~ 85°C)
• Matching shrouding design (shrouded 4-wall construction)
• Same contact material, finish, and mechanical dimensions
• Identical flammability rating (UL94 V-0)

The primary distinction between these parts is product status: the main part DF1EC-3P-2.5DSA(01) is obsolete, while DF1EC-3P-2.5DSA(36) maintains active status with current manufacturing and availability.

Parameter Comparison

Engineering Selection Recommendations

DF1EC-3P-2.5DSA(36) is the direct substitute for DF1EC-3P-2.5DSA(01). Selection of the active variant is justified by the following factors:

The substitute part maintains identical electrical and mechanical specifications across all critical parameters, ensuring functional compatibility in existing circuit designs and PCB layouts. The active product status of DF1EC-3P-2.5DSA(36) provides assured supply chain availability and manufacturing continuity, eliminating obsolescence risk associated with the original part designation.

The substitute part carries ROHS3 compliance and REACH unaffected status, providing additional regulatory alignment for applications subject to environmental and hazardous substance restrictions. These certifications are not specified for the obsolete variant but represent current manufacturing standards.

Both parts share identical moisture sensitivity level (MSL 1 - Unlimited), flammability rating (UL94 V-0), and export classification (EAR99), ensuring no changes to handling, storage, or regulatory documentation requirements.

Frequently Asked Questions (FAQ)

Q: Are DF1EC-3P-2.5DSA(01) and DF1EC-3P-2.5DSA(36) electrically and mechanically interchangeable?

A: Yes. Both parts are identical in connector type, contact configuration, pitch specification (2.50mm), number of positions (3), mounting method (through hole), current rating (3A), and operating temperature range (-35°C to 85°C). They are direct functional equivalents.

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