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

Part Overview

The DF13-2P-1.25DS(50) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-cable/wire applications with 2 positions at 0.049" (1.25mm) pitch. This connector features shrouded 4-wall construction with solder termination and detent lock fastening. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF13-2P-1.25DS(50) is determined by the following critical parameters:

• Pitch - Mating: 0.049" (1.25mm) — must match exactly for mechanical and electrical compatibility
• Number of Positions: 2 — connector must accommodate the same signal count
• Number of Rows: 1 — single-row configuration required
• Mounting Type: Through Hole, Right Angle — board attachment method must be identical
• Shrouding: Shrouded - 4 Wall — polarization and mechanical protection must be maintained
• Termination: Solder — connection method must remain consistent
• Fastening Type: Detent Lock — mating security mechanism must be preserved
• Voltage Rating: Minimum 150V — electrical performance must meet or exceed specification
• Current Rating: Minimum 1A — current handling capacity must be adequate
• Operating Temperature Range: Must encompass -35°C ~ 85°C or broader
• Material Flammability Rating: UL94 V-0 — safety compliance must be maintained

Two substitute parts meet these criteria: the DF13-2P-1.25DS(55) from Hirose Electric Co Ltd (same manufacturer, active product status) and the 0530480210 from Molex (PicoBlade 53048 series, active product status).

Parameter Comparison

Engineering Selection Recommendations

DF13-2P-1.25DS(55) is the primary substitute. This part is manufactured by Hirose Electric Co Ltd, the original equipment manufacturer, and maintains active product status. All critical mechanical and electrical parameters are identical to the obsolete DF13-2P-1.25DS(50). The only difference is the contact finish on the post (tin instead of unspecified), which does not affect functional compatibility. RoHS compliance is maintained. This part is the direct replacement for ongoing production and design support.

0530480210 (Molex PicoBlade 53048 series) is an alternative substitute. This part meets all critical substitution criteria with identical pitch, position count, mounting type, shrouding, termination, and fastening. The part maintains active product status and UL94 V-0 flammability rating. Minor differences include contact type (male blade versus male pin), contact material (phosphor bronze versus brass), contact finish (tin versus gold), insulation height (0.138" versus 0.142"), voltage rating (125V versus 150V), and operating temperature lower limit (-40°C versus -35°C). These differences do not prevent functional substitution in applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can DF13-2P-1.25DS(55) be used as a direct replacement for DF13-2P-1.25DS(50)?

A: Yes. Both parts are manufactured by Hirose Electric Co Ltd with identical pitch (0.049" / 1.25mm), position count (2), mounting type (through-hole right-angle), shrouding (4-wall), termination (solder), and fastening (detent lock). The DF13-2P-1.25DS(55) is active product status, making it the recommended substitute for the obsolete DF13-2P-1.25DS(50).

Q: What are the key differences between the Hirose DF13-2P-1.25DS(55) and the Molex 0530480210?

A: Both parts share identical pitch, position count, mounting configuration, and fastening type. Differences include contact type (pin versus blade), contact material (brass versus phosphor bronze), contact finish (gold versus tin), insulation height (3.60mm versus 4.60mm), voltage rating (150V versus 125V), and operating temperature range (-35°C to 85°C versus -40°C to 85°C). These differences do not prevent functional substitution within the specified operating parameters.

Q: Is the voltage rating difference between DF13-2P-1.25DS(50) at 150V and 0530480210 at 125V significant?

A: The voltage rating difference must be evaluated against your application requirements. If your design operates at or below 125V, the Molex 0530480210 is suitable. If your design requires 150V rating, the Hirose DF13-2P-1.25DS(55) is the appropriate choice.

Q: Are all three parts RoHS compliant?

A: Yes. The DF13-2P-1.25DS(50) and DF13-2P-1.25DS(55) are RoHS Compliant. The Molex 0530480210 is ROHS3 Compliant. All three parts meet RoHS requirements.

Q: Can the contact finish difference (gold versus tin) affect connector performance?

A: Contact finish affects mating surface characteristics and corrosion resistance. Gold finish provides superior corrosion resistance and lower contact resistance. Tin finish is suitable for general-purpose applications with adequate environmental protection. Selection depends on your application's environmental exposure and performance requirements.

Q: What is the significance of the insulation height difference (3.60mm versus 4.60mm)?

A: The insulation height difference of 0.10mm is minimal and does not affect mechanical compatibility or functional performance in standard board-to-cable applications. Both dimensions accommodate standard PCB layouts and mating connector designs.
