Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF13C-4P-1.25V(20) is determined by the following critical parameters that must remain constant:

• Pitch - Mating: 0.049" (1.25mm)
• Number of Positions: 4
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Detent Lock
• Current Rating: 1A
• Voltage Rating: 150V
• Insulation Height: 0.189" (4.80mm)
• Contact Shape: Square
• Contact Material: Brass
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional compatibility in board-to-cable/wire applications. Variations in shrouding design (3-wall vs. 4-wall), insulation material composition, contact finish thickness, and product status are noted but do not prevent substitution when core parameters align.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using DF13C-4P-1.25V(20), the following selection criteria apply based on product status and compliance:

DF13C-4P-1.25V(75) is the direct equivalent from Hirose Electric Co Ltd within the same DF13 series. This part maintains identical electrical and mechanical specifications with Last Time Buy status, providing continuity within the original manufacturer's product line. This option is suitable for designs requiring Hirose-specific qualification or where existing supply chain relationships are established.

M30-6000446 from Harwin Inc. is an active product offering long-term availability and supply continuity. This part meets all core substitution criteria with Active product status. The M30 series features 4-wall shrouding compared to the 3-wall design of the DF13C, and uses Polyamide (PA6T) Nylon 6T insulation material. The operating temperature range is -25°C ~ 85°C, which is narrower at the lower end compared to the DF13C range of -35°C ~ 85°C. Selection of this part requires confirmation that the narrower temperature range and enhanced shrouding design are compatible with application requirements.

Frequently Asked Questions (FAQ)

Q: Can DF13C-4P-1.25V(75) be used as a direct replacement for DF13C-4P-1.25V(20)?

A: Yes. Both parts are from Hirose Electric Co Ltd DF13 series and share identical electrical and mechanical specifications including pitch, position count, current rating, voltage rating, mounting type, and termination method. The primary difference is packaging (Tube for the 75 variant) and product status (Last Time Buy vs. Obsolete).

Q: What are the key differences between the Hirose DF13C-4P-1.25V(75) and the Harwin M30-6000446?

A: Both parts maintain the same 1.25mm pitch, 4-position configuration, 1A current rating, and 150V voltage rating. The M30-6000446 features 4-wall shrouding versus 3-wall on the DF13C, uses PA6T insulation material instead of standard PA, and has a narrower operating temperature range (-25°C to 85°C versus -35°C to 85°C). The M30-6000446 offers Active product status for long-term availability.

Q: Are there compatibility concerns with the 4-wall shrouding on the M30-6000446 compared to the 3-wall design of the DF13C?

A: The 4-wall shrouding on the M30-6000446 provides enhanced mechanical protection and mating guidance. Compatibility depends on the mating connector design and PCB layout. Designs using standard DF13 series receptacles should be evaluated for fit with the increased shrouding profile.

Q: Does the operating temperature difference affect substitution suitability?

A: The M30-6000446 operates from -25°C to 85°C, while the DF13C-4P-1.25V(20) operates from -35°C to 85°C. If the application requires operation below -25°C, the M30-6000446 is not suitable. For applications within the -25°C to 85°C range, the M30-6000446 meets temperature requirements.

Q: What is the significance of the insulation material difference between PA and PA6T?

A: Both Polyamide (PA) and Polyamide (PA6T) are nylon-based insulation materials meeting UL94 V-0 flammability requirements. PA6T (polyamide 6T) offers enhanced thermal and chemical resistance properties. This material difference does not prevent substitution for standard board-to-cable/wire applications.

Q: Are all three parts RoHS compliant?

A: The DF13C-4P-1.25V(20) does not specify RoHS status in the provided data. The DF13C-4P-1.25V(75) is RoHS Compliant. The M30-6000446 is ROHS3 Compliant and REACH Unaffected. Designs requiring RoHS compliance should specify either the DF13C-4P-1.25V(75) or M30-6000446.
