DF1-4PD-2.5C Equivalent & Substitute Parts

Part Overview

The DF1-4PD-2.5C is a 4-position rectangular connector housing manufactured by Hirose Electric Co Ltd, designed as a header with male pin contacts and 2.50mm pitch. This part is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations. The connector operates as a panel-mount assembly with crimp termination and is available in brown coloring.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF1-4PD-2.5C is determined by the following critical parameters that must remain consistent:

• Number of Positions: 4 positions required
• Pitch: 0.098" (2.50mm) spacing mandatory
• Number of Rows: Single row configuration
• Contact Type: Male pin contacts
• Mounting Type: Panel mount capability
• Contact Termination: Crimp or compatible termination method
• Connector Category: Rectangular connectors within the DF series family

The DF1BA-4EP-2.5RC qualifies as a substitute based on matching these core electrical and mechanical parameters. While the substitute represents an active product from the same manufacturer family, differences in connector type (plug versus header) and color do not prevent functional substitution when system design accommodates the physical form factor change.

Parameter Comparison

Engineering Selection Recommendations

The DF1BA-4EP-2.5RC is the designated manufacturer substitute for the obsolete DF1-4PD-2.5C. Selection of this substitute is supported by:

• Product Status: The substitute maintains active production status, ensuring long-term availability and supply chain continuity
• Compliance: The substitute carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements
• Electrical Compatibility: Identical pitch, position count, and contact configuration ensure direct electrical interface compatibility
• Mechanical Compatibility: Both parts maintain panel mount capability with equivalent MSL ratings

The primary design consideration is the connector type transition from header to plug housing, which requires verification that the mating interface in the target application can accommodate the substitute form factor.

Frequently Asked Questions (FAQ)

Q: Can the DF1BA-4EP-2.5RC directly replace the DF1-4PD-2.5C in existing assemblies?

A: Electrical compatibility is confirmed through matching pitch (2.50mm), position count (4), and contact configuration (male pin). Physical compatibility depends on the mating connector type in your application. The substitute uses a plug housing versus the original header design.

Q: What is the significance of the product status difference?

A: The main part is classified as obsolete, indicating discontinued production. The substitute maintains active status, providing assured availability for new procurements and ongoing support.

Q: Are there differences in contact termination methods?

A: The main part specifies crimp termination only. The substitute supports both crimp and IDC (insulation displacement contact) termination options, providing additional assembly flexibility.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the DF1-4PD-2.5C and DF1BA-4EP-2.5RC carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints for storage or handling.

Q: What packaging considerations apply to the substitute?

A: The substitute is supplied in bulk packaging, whereas the main part packaging specification was not provided. Verify bulk packaging compatibility with your procurement and assembly processes.
