Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DF13B-3P-1.25V(21) are identified based on strict equivalence of the following critical parameters:

• Connector type: Header
• Contact type: Male Pin
• Pitch: 0.049" (1.25mm)
• Number of positions: 3
• Number of rows: 1
• Mounting type: Surface Mount
• Termination: Solder
• Fastening type: Detent Lock
• Shrouding: Shrouded - 3 Wall
• Current rating: 1A
• Voltage rating: 150V or higher
• Material flammability rating: UL94 V-0
• RoHS compliance: Yes

The substitute part 10114828-10103LF (Amphenol ICC/FCI) meets all critical substitution criteria. Both parts are active products with equivalent electrical performance, mechanical compatibility, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the DF13B-3P-1.25V(21) and 10114828-10103LF are active products with full RoHS compliance and UL94 V-0 flammability certification. The Amphenol ICC/FCI substitute part provides an extended operating temperature range (-40°C to 105°C versus -35°C to 85°C) and is available in higher inventory quantity (6300 units versus 1900 units). The voltage rating of the substitute part is 125V, which is lower than the primary part's 150V rating; applications requiring the full 150V rating should retain the DF13B-3P-1.25V(21). For applications operating within 125V specifications, the 10114828-10103LF offers equivalent electrical and mechanical performance with improved temperature operating margins.

Frequently Asked Questions (FAQ)

Q: What makes 10114828-10103LF a valid substitute for DF13B-3P-1.25V(21)?

A: Both connectors share identical critical specifications: 3-position, 1.25mm pitch, surface mount header with male pins, solder termination, detent lock fastening, 3-wall shrouding, 1A current rating, tin contact finish, UL94 V-0 flammability rating, and RoHS compliance. These parameters ensure mechanical and electrical compatibility in board-to-cable/wire applications.

Q: Are there voltage rating differences between these parts?

A: Yes. The DF13B-3P-1.25V(21) is rated for 150V, while the 10114828-10103LF is rated for 125V. Applications requiring operation at voltages above 125V must use the primary part. Applications operating at 125V or below can use either part.

Q: What is the temperature operating range difference?

A: The DF13B-3P-1.25V(21) operates from -35°C to 85°C. The 10114828-10103LF operates from -40°C to 105°C, providing a wider temperature envelope. Selection should be based on application temperature requirements.

Q: Are both parts available in the same packaging?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Can these connectors be used interchangeably on the same PCB?

A: Yes, provided the application voltage requirement does not exceed 125V and the operating temperature range is compatible with the selected part. The identical pitch, position count, mounting type, and mechanical interface ensure footprint compatibility.
