Key Parameters

Substitute Part Grouping Explanation

The DF14-2P-1.25H(52) qualifies as a direct substitute based on the following critical parameters:

• Identical series designation (DF14)
• Matching connector type (Header) and contact type (Male Pin)
• Same number of positions (2) and mating pitch (1.25mm)
• Identical mounting configuration (Surface Mount, Right Angle)
• Matching electrical ratings (1A current, 150V voltage)
• Identical operating temperature range (-35°C ~ 85°C)
• Same shrouding style (Shrouded - 4 Wall)
• Equivalent insulation material (Polyamide/Nylon)
• Matching flammability rating (UL94 V-0)

The primary distinction is product status: DF14-2P-1.25H(56) is obsolete, while DF14-2P-1.25H(52) is active with significantly higher inventory availability (2691 pcs vs. 817 pcs).

Parameter Comparison

Engineering Selection Recommendations

The DF14-2P-1.25H(52) is the appropriate selection for applications currently using or specifying the DF14-2P-1.25H(56). Both parts maintain identical electrical and mechanical specifications within the DF14 series. The substitute part offers the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance provides enhanced regulatory alignment compared to RoHS compliance
• Tape & Reel packaging supports automated assembly processes
• Significantly higher inventory availability (2691 pcs) reduces procurement lead time

The electrical performance, mechanical fit, and thermal operating range are functionally equivalent. Both parts are rated for 1A current and 150V voltage with identical contact geometry and mounting configuration.

Frequently Asked Questions (FAQ)

Q: Are DF14-2P-1.25H(56) and DF14-2P-1.25H(52) mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (Surface Mount, Right Angle), pitch (1.25mm), number of positions (2), and insulation height (2.50mm). They are mechanically interchangeable in board-level applications.

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

A: The primary differences are product status (obsolete vs. active) and packaging format. The DF14-2P-1.25H(52) is supplied in Tape & Reel packaging, while the DF14-2P-1.25H(56) does not specify packaging. The DF14-2P-1.25H(52) also carries ROHS3 compliance versus RoHS compliance.

Q: Can I use DF14-2P-1.25H(52) in existing designs specified for DF14-2P-1.25H(56)?

A: Yes. The electrical ratings (1A, 150V), operating temperature range (-35°C to 85°C), and mechanical specifications are identical. No design modifications are required.

Q: Why is DF14-2P-1.25H(56) listed as obsolete?

A: Product obsolescence is determined by the manufacturer. The DF14-2P-1.25H(52) serves as the active equivalent within the same series and maintains full functional compatibility.

Q: What is the difference in contact finish between these parts?

A: DF14-2P-1.25H(56) has Tin-Copper finish on the post with 39.4µin thickness. DF14-2P-1.25H(52) has Gold finish on the post with 3.94µin thickness. Both have Gold mating contact finish. The mating contact specifications are equivalent.
