Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1-10P-2.5DSA(05) is determined by the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch specification (2.5mm)
• Number of positions (10)
• Number of rows (1)
• Mounting method (Through Hole)
• Termination method (Solder)
• Voltage rating (250V minimum)
• Operating temperature range (must encompass or exceed -30°C ~ 85°C)
• Compliance certifications (UL94 V-0, ROHS3)

The DF1B-10P-2.5DSA(01) meets these core substitution criteria. While secondary parameters such as shrouding configuration, contact finish, and fastening type differ, these variations do not prevent functional equivalence in applications designed for the DF1-10P-2.5DSA(05).

Parameter Comparison

Engineering Selection Recommendations

The DF1B-10P-2.5DSA(01) is the designated substitute for the DF1-10P-2.5DSA(05). Both parts maintain identical core electrical and mechanical specifications: 10-position, 2.5mm pitch, through-hole solder termination, 250V voltage rating, and UL94 V-0 flammability compliance.

The DF1B series offers an extended operating temperature range (-35°C ~ 85°C versus -30°C ~ 85°C), providing additional thermal margin. The DF1B-10P-2.5DSA(01) carries Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the original part.

Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for new designs and production transitions.

Frequently Asked Questions (FAQ)

Q: Can the DF1B-10P-2.5DSA(01) be used as a direct replacement for the DF1-10P-2.5DSA(05)?

A: Yes. Both connectors share identical pitch (2.5mm), position count (10), mounting method (through-hole), and electrical ratings (250V). The DF1B series is the active production equivalent.

Q: What are the physical differences between these parts?

A: The DF1B-10P-2.5DSA(01) features 4-wall shrouding compared to 1-wall shrouding on the DF1-10P-2.5DSA(05). The DF1B also incorporates a keying slot and uses gold contact finish versus tin finish on the original part. Insulation height and overall contact length differ slightly due to series design changes.

Q: Are there current rating differences?

A: The DF1-10P-2.5DSA(05) specifies 3A current rating. The DF1B-10P-2.5DSA(01) does not list a current rating in the provided specifications. Applications requiring specific current capacity should be evaluated against actual mating connector specifications and PCB trace design.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH Unaffected, and carry UL94 V-0 flammability rating. Moisture sensitivity level is 1 (Unlimited) for both.

Q: What is the temperature operating range difference?

A: The DF1-10P-2.5DSA(05) operates from -30°C to 85°C. The DF1B-10P-2.5DSA(01) extends the lower limit to -35°C, providing 5°C additional cold-temperature margin.

Q: Why is the original part marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. The DF1B series represents the current production line for this connector category, ensuring long-term availability for new designs and production continuity.
