Substitute Part Grouping Explanation

Substitution eligibility for the DF13-7P-1.25DS(50) is determined by the following critical parameters:

Connector pitch: 0.049" (1.25mm) mating pitch
Position count: 7 positions in a single row
Mounting configuration: Through-hole, right-angle orientation
Termination method: Solder termination
Fastening mechanism: Detent lock
Electrical ratings: Minimum 150V voltage rating and 1A current capacity
Shrouding: 4-wall shrouded design
Insulation material: Polyamide (PA), Nylon
Flammability rating: UL94 V-0

Two substitute parts meet these criteria: the DF13-7P-1.25DS(55) from Hirose Electric Co Ltd (same manufacturer, active product status) and the 0530480710 from Molex (PicoBlade 53048 series, cross-manufacturer equivalent).

Engineering Selection Recommendations

DF13-7P-1.25DS(55) is the primary substitute for the obsolete DF13-7P-1.25DS(50). Both connectors are manufactured by Hirose Electric Co Ltd and share identical electrical and mechanical specifications. The DF13-7P-1.25DS(55) maintains active product status with higher inventory availability (968 Pcs vs. 796 Pcs), ensuring long-term procurement viability. The only documented difference is the contact finish on the post (tin vs. unspecified on the original), which does not affect functional compatibility for standard solder termination applications.

0530480710 (Molex PicoBlade 53048 series) serves as a cross-manufacturer equivalent. This connector meets all critical substitution parameters: 1.25mm pitch, 7-position configuration, through-hole right-angle mounting, solder termination, and detent lock fastening. The Molex part operates at a lower voltage rating (125V vs. 150V) and features tin contact finish on both mating and post surfaces. The insulation height is marginally lower (0.138" vs. 0.142"), and the contact material differs (phosphor bronze vs. brass). The part maintains ROHS3 compliance and unlimited moisture sensitivity rating. Significantly higher inventory availability (44,862 Pcs) supports supply chain continuity.

Selection between the two substitutes depends on design voltage requirements and contact material specifications. For applications requiring the full 150V rating and gold-plated mating contacts, the DF13-7P-1.25DS(55) is the appropriate choice. For applications operating below 125V with tin-plated contacts, the 0530480710 offers superior supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the DF13-7P-1.25DS(55) be used as a direct replacement for the DF13-7P-1.25DS(50)?

A: Yes. Both connectors are manufactured by Hirose Electric Co Ltd and share identical pitch (1.25mm), position count (7), mounting type (through-hole right-angle), termination method (solder), and fastening mechanism (detent lock). The DF13-7P-1.25DS(55) is the active product variant and is fully compatible.

Q: What are the key differences between the Hirose DF13-7P-1.25DS(55) and the Molex 0530480710?

A: The primary differences are voltage rating (150V vs. 125V), contact material (brass vs. phosphor bronze), contact finish on mating surface (gold vs. tin), and insulation height (0.142" vs. 0.138"). Both maintain 1.25mm pitch, 7-position configuration, and detent lock fastening. The Molex part operates at a lower temperature minimum (-40°C vs. -35°C).

Q: Is the Molex 0530480710 suitable for applications requiring 150V operation?

A: No. The 0530480710 is rated for 125V maximum. Applications requiring 150V operation must use the DF13-7P-1.25DS(55) or equivalent Hirose DF13 series connectors rated for 150V.

Q: Are there packaging differences between these substitutes?

A: The DF13-7P-1.25DS(50) and DF13-7P-1.25DS(55) packaging is not specified in available data. The Molex 0530480710 is supplied in tray packaging.

Q: Do all three connectors meet UL94 V-0 flammability requirements?

A: Yes. The DF13-7P-1.25DS(50), DF13-7P-1.25DS(55), and 0530480710 all carry UL94 V-0 material flammability ratings.

Q: What is the moisture sensitivity level for these connectors?

A: All three connectors are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
