Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF13C-4P-1.25V(21) is determined by the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch specification (0.049" / 1.25mm)
• Number of positions (4)
• Number of rows (1)
• Mounting type (Surface Mount)
• Termination method (Solder)
• Current rating (1A minimum)
• Voltage rating (150V minimum)
• Operating temperature range (must encompass -35°C to 85°C)
• Flammability rating (UL94 V-0)
• RoHS compliance status

The identified substitute parts meet these core electrical and mechanical requirements while maintaining functional equivalence in board-to-cable/wire applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and meet UL94 V-0 flammability requirements. The DF13C-4P-1.25V(21) and M30-6000446 both support the full 150V voltage rating, while the 10114828-10104LF operates at 125V. The 10114828-10104LF provides the widest operating temperature range (-40°C ~ 105°C), exceeding the primary part specification. The M30-6000446 features 4-wall shrouding compared to the 3-wall design of the primary part, offering enhanced mechanical protection. All parts are RoHS compliant and carry MSL 1 moisture sensitivity ratings. Selection should be based on voltage requirements, temperature operating envelope, shrouding preference, and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can the 10114828-10104LF be used in applications requiring 150V operation?

A: No. The 10114828-10104LF is rated for 125V maximum, which is below the 150V requirement of the DF13C-4P-1.25V(21). Use only in applications with voltage requirements of 125V or lower.

Q: What is the difference between 3-wall and 4-wall shrouding?

A: Shrouding refers to the insulation walls surrounding the connector contacts. The DF13C-4P-1.25V(21) and 10114828-10104LF feature 3-wall shrouding, while the M30-6000446 features 4-wall shrouding. Four-wall designs provide additional mechanical protection and contact isolation.

Q: Are all substitute parts compatible with the same mating connectors?

A: All parts share identical pitch (1.25mm), position count (4), and row configuration (1 row), ensuring mechanical compatibility with the same mating connectors. Contact geometry differences (square vs. rectangular) do not affect mating compatibility.

Q: Does the 10114828-10104LF support the full operating temperature range of the primary part?

A: No. The 10114828-10104LF operates from -40°C to 105°C, which does not fully encompass the primary part's -35°C to 85°C range. However, the substitute's range exceeds the primary specification at the upper temperature limit.

Q: What packaging formats are available for each part?

A: The DF13C-4P-1.25V(21) is supplied in Tape & Reel (TR) format. The 10114828-10104LF is available in Cut Tape (CT) and Digi-Reel® formats. The M30-6000446 is supplied in Tube packaging.

Q: Are all parts RoHS compliant?

A: Yes. The DF13C-4P-1.25V(21) and M30-6000446 are ROHS3 compliant. The 10114828-10104LF is RoHS compliant. All parts meet regulatory requirements for hazardous substance restrictions.
