DF13-2P-1.25DSA(50) Equivalent & Substitute Parts

Part Overview

The DF13-2P-1.25DSA(50) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting in board-to-cable/wire applications. This 2-position, 1.25mm pitch connector features shrouded 4-wall construction with solder termination and detent lock fastening. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF13-2P-1.25DSA(50) is determined by strict alignment of the following critical parameters:

• Pitch - Mating: 0.049" (1.25mm) — must match exactly for mechanical compatibility
• Number of Positions: 2 — connector must accommodate identical pin count
• Number of Rows: 1 — single-row configuration required
• Mounting Type: Through Hole — PCB mounting method must be identical
• Termination: Solder — connection method must be solder-based
• Fastening Type: Detent Lock — mechanical locking mechanism must be present
• Shrouding: Shrouded - 4 Wall — housing configuration must provide equivalent protection
• Style: Board to Cable/Wire — application context must remain unchanged
• Material Flammability Rating: UL94 V-0 — safety certification must be maintained or exceeded

The substitute part 0530470210 (Molex PicoBlade 53047 series) meets all critical substitution criteria. Variations in contact material (Phosphor Bronze vs. Brass), contact finish (Tin vs. Gold), and insulation material (Nylon 6/6 vs. Nylon) are within acceptable engineering tolerances for this connector category and do not preclude functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0530470210 (PicoBlade 53047 series) is the qualified substitute for the obsolete Hirose DF13-2P-1.25DSA(50). Selection is based on the following engineering criteria:

• All critical mechanical and electrical parameters align with the original specification
• The substitute maintains UL94 V-0 flammability compliance
• MSL rating of 1 (Unlimited) is preserved, eliminating moisture sensitivity concerns
• The substitute part is in active production status with high inventory availability (54,434 pcs), ensuring supply chain continuity
• Both connectors are RoHS and REACH compliant, meeting current regulatory requirements
• Dimensional compatibility is confirmed through matching pitch, position count, and post length specifications

The minor variations in contact material, finish, and insulation material do not impact functional performance in standard board-to-cable/wire applications within the specified operating temperature range of -35°C to 85°C.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0530470210 be used as a direct replacement for the Hirose DF13-2P-1.25DSA(50)?

A: Yes. Both connectors share identical pitch (1.25mm), position count (2), row configuration (1), mounting method (through hole), termination type (solder), and fastening mechanism (detent lock). Mechanical and electrical compatibility is confirmed.

Q: What are the key differences between these two connectors?

A: The primary differences are contact material (Brass vs. Phosphor Bronze), contact finish (Gold vs. Tin), and insulation material formulation (Nylon vs. Nylon 6/6). These variations do not affect functional performance in standard applications.

Q: Is the Molex substitute available in the same packaging as the original?

A: The Molex 0530470210 is supplied in Tray packaging, whereas the original Hirose part packaging is not specified. Verify packaging requirements for your procurement and assembly processes.

Q: Are there any compliance or certification concerns with substitution?

A: No. Both parts maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity classification. The Molex part is ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards.

Q: What is the mated stacking height for the Molex substitute?

A: The Molex 0530470210 mated stacking height is not specified in the available data. The original Hirose part specifies 5.3mm. Confirm dimensional requirements for your specific application before final design release.

Q: Are current and voltage ratings identical between the two connectors?

A: The original Hirose part specifies 1A current rating and 150V voltage rating. The Molex substitute does not provide explicit current and voltage ratings in the available data. Verify electrical performance requirements against Molex technical documentation before implementation.
