DF13EA-40DP-1.25V(21) Equivalent & Substitute Parts

Part Overview

The DF13EA-40DP-1.25V(21) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for surface mount applications with 40 positions at 1.25mm pitch. This connector is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement planning. The part operates across a temperature range of -35°C to 85°C and is rated for 1A current at 150V, with shrouded 4-wall construction and push-pull fastening.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF13EA-40DP-1.25V(21) is based on the following critical parameters that must remain constant:

• Connector type (Header)
• Number of positions (40)
• Number of rows (2)
• Pitch specification (0.049" / 1.25mm)
• Row spacing (0.049" / 1.25mm)
• Mounting type (Surface Mount)
• Contact type (Male Pin)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Insulation material (Polyamide/Nylon)
• Operating temperature range (-35°C ~ 85°C)
• Material flammability rating (UL94 V-0)

The DF13EA-40DP-1.25V(22) qualifies as a substitute within the DF13 series. Variations in shrouding configuration (4-wall versus 2-wall), contact finish specifications, and voltage rating do not preclude functional substitution when mechanical and electrical requirements align with the application constraints.

Parameter Comparison

Engineering Selection Recommendations

The DF13EA-40DP-1.25V(22) is the primary substitute for the obsolete DF13EA-40DP-1.25V(21). Both parts maintain identical mechanical compatibility, pitch specifications, and core electrical characteristics necessary for board-to-cable/wire applications.

The DF13EA-40DP-1.25V(22) carries active product status from Hirose Electric Co Ltd, ensuring ongoing availability and manufacturing support. Both parts maintain RoHS compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and consumer applications.

The voltage rating differential (150V versus 29.9VAC/DC) and shrouding configuration change (4-wall to 2-wall) represent the primary distinctions. Selection between these variants depends on application-specific voltage requirements and mechanical space constraints. The 2-wall shrouding of the substitute part reduces overall envelope dimensions while maintaining electrical isolation and contact retention.

Frequently Asked Questions (FAQ)

Q: Can the DF13EA-40DP-1.25V(22) directly replace the DF13EA-40DP-1.25V(21) in existing designs?

A: Yes, provided the application voltage requirement does not exceed 29.9VAC/DC. The mechanical footprint, pitch, number of positions, and contact configuration are identical. PCB layout and mating connector compatibility remain unchanged.

Q: What is the significance of the shrouding difference between 4-wall and 2-wall configurations?

A: The 4-wall shrouding on the original part provides complete perimeter protection, while the 2-wall configuration on the substitute reduces overall height and width. Both configurations maintain contact isolation and solder retention. Selection depends on available PCB space and mechanical clearance requirements.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the DF13EA-40DP-1.25V(21) and DF13EA-40DP-1.25V(22) operate across -35°C to 85°C, ensuring thermal compatibility across standard industrial and commercial applications.

Q: What is the current-carrying capacity per contact?

A: Both parts are rated for 1A per contact. The substitute part explicitly specifies "1A per Contact," confirming equivalent current distribution capability.

Q: Does the contact finish difference affect substitution suitability?

A: The original part specifies Tin-Copper finish at 39.4µin (1.00µm) thickness, while the substitute specifies Tin finish. Both finishes provide adequate corrosion resistance and solderability for standard PCB assembly processes. Finish selection does not preclude functional substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both the DF13EA-40DP-1.25V(21) and DF13EA-40DP-1.25V(22) are RoHS compliant and carry UL94 V-0 material flammability certification.
