DF13EA-20DP-1.25V(21) Equivalent & Substitute Parts

Part Overview

The DF13EA-20DP-1.25V(21) is a surface mount rectangular connector header manufactured by Hirose Electric Co Ltd. This 20-position connector operates at 1.25mm pitch with a 2-row configuration and is designed for board-to-cable/wire applications. The part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing production and maintenance applications. The DF13EA-20DP-1.25V(22) serves as the manufacturer-recommended substitute, offering identical mechanical and electrical specifications with active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

The DF13EA-20DP-1.25V(22) qualifies as a direct substitute based on the following critical parameters:

• Identical connector type, contact type, and series designation (DF13 Header)
• Matching position count (20 positions) and row configuration (2 rows)
• Identical mating pitch (0.049" / 1.25mm) and row spacing
• Identical mounting type (Surface Mount) and shrouding configuration (Shrouded - 4 Wall)
• Matching electrical ratings: 1A current capacity and 150V voltage rating
• Identical operating temperature range (-35°C ~ 85°C)
• Equivalent material flammability rating (UL94 V-0)
• Equivalent RoHS compliance status

The primary distinction is product status: the DF13EA-20DP-1.25V(21) is obsolete, while the DF13EA-20DP-1.25V(22) maintains active status with significantly higher inventory availability (3163 units versus 792 units).

Parameter Comparison

Engineering Selection Recommendations

The DF13EA-20DP-1.25V(22) is the manufacturer-designated substitute for the obsolete DF13EA-20DP-1.25V(21). Selection of the active part is supported by:

• Identical electrical and mechanical specifications across all critical parameters
• Active product status ensuring long-term availability and supply chain continuity
• Superior inventory levels (3163 units) compared to the obsolete variant
• Enhanced RoHS compliance designation (ROHS3 Compliant versus RoHS Compliant)
• Equivalent environmental and regulatory certifications (UL94 V-0, EAR99, HTSUS 8536.69.4040)

The fastening type difference (Push-Pull versus Detent Lock) and contact finish variation (Tin-Copper versus Tin) do not affect electrical performance or mechanical compatibility within the DF13 series connector ecosystem.

Frequently Asked Questions (FAQ)

Q: Are DF13EA-20DP-1.25V(21) and DF13EA-20DP-1.25V(22) mechanically interchangeable?

A: Yes. Both connectors share identical pitch (1.25mm), position count (20), row configuration (2), shrouding design (Shrouded - 4 Wall), and mounting type (Surface Mount). Mechanical compatibility is confirmed across all mating and installation parameters.

Q: What is the difference between Push-Pull and Detent Lock fastening types?

A: Push-Pull fastening uses a simple push-to-connect, pull-to-disconnect mechanism. Detent Lock fastening incorporates a locking feature that requires deliberate action to disconnect. Both fastening types maintain equivalent electrical performance and are suitable for board-to-cable/wire applications within the DF13 series.

Q: Does the contact finish difference affect electrical performance?

A: No. Both Tin-Copper and Tin contact finishes meet the same electrical specifications (1A current rating, 150V voltage rating) and provide equivalent corrosion resistance and conductivity for this connector class. The contact material (Brass) is identical in both variants.

Q: Why is the DF13EA-20DP-1.25V(21) listed as obsolete?

A: Product obsolescence reflects manufacturer discontinuation decisions. The DF13EA-20DP-1.25V(22) represents the active continuation of this connector line with identical performance characteristics and improved supply availability.

Q: Are there packaging differences between the two parts?

A: The DF13EA-20DP-1.25V(21) packaging is not specified in available data. The DF13EA-20DP-1.25V(22) is available in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both manual and automated assembly workflows.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage, handling, or assembly processes.
