Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1EC-11P-2.5DSA is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Number of positions (11)
• Pitch specification (2.5mm)
• Contact type (Male Pin)
• Mounting method (Through Hole)
• Current rating (3A)
• Operating temperature range (-35°C ~ 85°C)
• Shrouding configuration (Shrouded - 4 Wall)
• Contact material and finish (Brass with Tin plating)
• Insulation material (Polyamide/Nylon)
• Flammability rating (UL94 V-0)

Parts meeting all these parameters are classified as direct equivalents and may be substituted without design modification.

Parameter Comparison

Engineering Selection Recommendations

The DF1EC-11P-2.5DSA(05) is a direct equivalent substitute for the obsolete DF1EC-11P-2.5DSA. All electrical, mechanical, and dimensional parameters are identical across both parts. The primary distinction is product status: the substitute part is active and currently in production, whereas the original part is obsolete.

An additional consideration is regulatory compliance. The substitute part DF1EC-11P-2.5DSA(05) is RoHS Compliant, whereas the original part is RoHS non-compliant. This distinction may be relevant for applications subject to RoHS directives or customer specifications requiring RoHS-compliant components.

Both parts share identical moisture sensitivity levels (MSL 1), export classifications (EAR99), and tariff codes (8536.69.4040), ensuring consistency in supply chain handling and regulatory documentation.

Frequently Asked Questions (FAQ)

Q: Can DF1EC-11P-2.5DSA(05) be used as a direct replacement for DF1EC-11P-2.5DSA?

A: Yes. All electrical, mechanical, and dimensional specifications are identical. No design modification is required. The substitute part is pin-compatible and functionally equivalent.

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

A: The primary difference is product status. DF1EC-11P-2.5DSA is obsolete, while DF1EC-11P-2.5DSA(05) is active and in current production. Additionally, the substitute part is RoHS Compliant, whereas the original is RoHS non-compliant.

Q: Are there any compatibility concerns with PCB layouts or mating connectors?

A: No. Both parts maintain identical pitch (2.5mm), position count (11), contact geometry, and mounting specifications. Existing PCB layouts and mating connectors designed for DF1EC-11P-2.5DSA are fully compatible with DF1EC-11P-2.5DSA(05).

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 electrical characteristics and current ratings (3A).

Q: Are moisture sensitivity levels the same?

A: Yes. Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage or handling.
