Substitute Part Grouping Explanation

Substitution for the DF13-4P-1.25DS(20) is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (4)
• Mating pitch (0.049" / 1.25mm)
• Mounting configuration (Through Hole, Right Angle)
• Electrical ratings (1A current, 150V voltage)
• Operating temperature range (-35°C ~ 85°C)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Detent Lock)

The substitute part DF13-4P-1.25DS(25) maintains identical electrical and mechanical specifications while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The DF13-4P-1.25DS(25) is the direct substitute for the obsolete DF13-4P-1.25DS(20). Both parts are manufactured by Hirose Electric Co Ltd within the DF13 series and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product status: DF13-4P-1.25DS(20) is obsolete, while DF13-4P-1.25DS(25) maintains active status with significantly higher inventory availability (2289 units versus 997 units). The substitute part carries ROHS3 compliance, representing an updated regulatory classification compared to the RoHS compliance of the original part.

Both parts satisfy UL94 V-0 flammability requirements and maintain MSL 1 (Unlimited) moisture sensitivity classification, ensuring equivalent performance in standard industrial applications.

Frequently Asked Questions (FAQ)

Q: Are DF13-4P-1.25DS(20) and DF13-4P-1.25DS(25) mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (1.25mm), position count (4), mounting type (through-hole right-angle), and shrouding configuration (4-wall). They are direct mechanical substitutes.

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

A: The primary difference is product lifecycle status. DF13-4P-1.25DS(20) is obsolete, while DF13-4P-1.25DS(25) is active. The suffix designation (20 versus 25) indicates different manufacturing batches or packaging configurations. Both maintain identical electrical and mechanical performance.
