Substitute Part Grouping Explanation

The DF13-3P-1.25DSA(20) can be substituted with the 10114829-10103LF based on the following critical parameters that determine functional equivalence:

• Connector Type & Configuration: Both are header connectors with male pin contacts, 3 positions, single row, 1.25mm pitch
• Mechanical Interface: Both feature shrouded 4-wall construction, through-hole mounting, solder termination, and detent lock fastening
• Electrical Performance: Both rated for 1A current and meet UL94 V-0 flammability requirements
• Application Compatibility: Both designed for board-to-cable/wire interconnection with identical mating pitch and position count

The substitute part maintains functional compatibility across all critical electrical and mechanical parameters required for direct replacement in the same circuit board layout and mating interface.

• Electrical & Mechanical Compatibility: Identical pitch, position count, mounting type, termination method, and fastening mechanism ensure direct replacement without circuit board redesign
• Operating Conditions: The substitute supports an extended operating temperature range (-40°C ~ 105°C) compared to the original part (-35°C ~ 85°C), providing broader application flexibility
• Inventory Availability: The substitute is currently in stock with 2256 pieces available

Frequently Asked Questions (FAQ)

Q: Can the 10114829-10103LF be used as a direct replacement without modifying the circuit board?

A: Yes. Both connectors share identical pitch (1.25mm), position count (3), mounting type (through-hole), and fastening mechanism (detent lock). The mating interface and board footprint are compatible.

Q: What are the differences between the original and substitute part?

A: Key differences include contact material (Brass vs. Phosphor Bronze), insulation material (Polyamide/Nylon vs. Liquid Crystal Polymer), contact shape (Square vs. Rectangular), and operating temperature range. The substitute supports -40°C ~ 105°C versus -35°C ~ 85°C for the original. Voltage rating differs slightly (125V vs. 150V).

Q: Does the substitute meet current environmental and compliance standards?

A: Yes. The 10114829-10103LF is RoHS Compliant and REACH Affected, meeting current regulatory requirements. Both parts carry UL94 V-0 flammability certification.

Q: Are there packaging considerations when sourcing the substitute?

A: The substitute is available in Cut Tape (CT) packaging. Confirm packaging requirements for your procurement process.

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

A: Both the original and substitute parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without special moisture control measures.

Q: Is the extended operating temperature range of the substitute beneficial?

A: The substitute's extended range (-40°C ~ 105°C) provides additional margin for applications operating at temperature extremes, though the original specification (-35°C ~ 85°C) remains the design requirement.
