Key Parameters

Substitute Part Grouping Explanation

The DF14-4P-1.25H(52) qualifies as a direct substitute based on the following critical parameters:

• Connector Series: Both parts belong to the DF14 series
• Position Count: Both feature 4 positions
• Mating Pitch: Both use 0.049" (1.25mm) pitch
• Connector Type: Both are header connectors with male pins
• Mounting Configuration: Both are surface mount, right-angle designs
• Shrouding: Both feature shrouded 4-wall construction
• Electrical Ratings: Both support 1A current and 150V voltage
• Operating Temperature Range: Both operate across -35°C ~ 85°C
• Flammability Rating: Both meet UL94 V-0
• Termination Method: Both use solder termination with push-pull fastening

The primary distinction is product status: DF14-4P-1.25H(56) is obsolete, while DF14-4P-1.25H(52) is active with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The DF14-4P-1.25H(52) is the direct substitute for the obsolete DF14-4P-1.25H(56). Both parts maintain identical electrical and mechanical specifications across all critical parameters. The substitute part carries active product status with higher inventory availability and is supplied in Tape & Reel packaging, which is standard for production environments.

The DF14-4P-1.25H(52) meets ROHS3 compliance, providing enhanced regulatory alignment compared to the original part's RoHS compliance designation. This upgrade in compliance status supports long-term supply chain sustainability and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Are DF14-4P-1.25H(56) and DF14-4P-1.25H(52) mechanically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, mounting configurations, and board interface specifications. The 4-position, 1.25mm pitch header design, shrouded 4-wall construction, and surface mount right-angle mounting are identical across both part numbers.

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

A: The primary differences are product status and packaging. DF14-4P-1.25H(56) is obsolete, while DF14-4P-1.25H(52) is active. The substitute part is supplied in Tape & Reel packaging and carries ROHS3 compliance versus RoHS compliance on the original.

Q: Can I use DF14-4P-1.25H(52) in designs currently specified for DF14-4P-1.25H(56)?

A: Yes. The electrical ratings (1A, 150V), operating temperature range (-35°C ~ 85°C), and all mechanical specifications are identical. The connector will function identically in the same application.

Q: What is the significance of the packaging difference?

A: DF14-4P-1.25H(52) is supplied in Tape & Reel format, which is standard for automated assembly processes. This packaging format supports high-volume production environments and is compatible with standard pick-and-place equipment.

Q: Does the ROHS3 compliance of DF14-4P-1.25H(52) affect compatibility?

A: No. ROHS3 compliance is a regulatory enhancement that ensures the part meets current environmental standards. This does not affect electrical or mechanical compatibility with existing designs.

Q: Are there any contact finish differences between these parts?

A: The mating contact finish is gold on both parts. The post contact finish differs: DF14-4P-1.25H(56) uses tin-copper, while DF14-4P-1.25H(52) uses gold. Both finishes support solder termination and maintain equivalent electrical performance.
