Engineering Selection Recommendations

The DF13-4P-1.25DS(55) from Hirose Electric Co Ltd is the primary equivalent substitute. This part maintains identical electrical and mechanical specifications to the obsolete DF13-4P-1.25DS(50), with the distinction of active product status. Both parts share the same series designation, pitch, position count, mounting configuration, and compliance certifications. The DF13-4P-1.25DS(55) is recommended for direct replacement in new designs and production transitions.

The Molex 0530480410 (PicoBlade 53048 series) provides an alternative cross-platform substitute. This connector maintains the critical parameters of 1.25mm pitch, 4-position configuration, through-hole right-angle mounting, solder termination, and detent lock fastening. The Molex part operates across an extended temperature range (-40°C to 85°C) and carries ROHS3 compliance. Differences include tin contact finish on mating surfaces (versus gold on the Hirose parts), phosphor bronze contact material (versus brass), and a marginally lower insulation height (0.138" versus 0.142"). These variations remain within acceptable engineering tolerances for equivalent connector operation.

Frequently Asked Questions (FAQ)

Q: Can the DF13-4P-1.25DS(55) be used as a direct replacement for the DF13-4P-1.25DS(50)?

A: Yes. Both connectors share identical pitch (1.25mm), position count (4), mounting type (through-hole right-angle), termination method (solder), and fastening mechanism (detent lock). The primary difference is product status: the (50) variant is obsolete while the (55) is active. Electrical and mechanical specifications are equivalent.

Q: What are the key differences between the Hirose DF13-4P-1.25DS(55) and the Molex 0530480410?

A: Both maintain 1.25mm pitch and 4-position configuration. The Molex part features tin contact finish on mating surfaces and phosphor bronze contact material, compared to gold-plated brass on the Hirose part. The Molex connector has a slightly lower insulation height (0.138" versus 0.142") and operates at 125V versus 150V. The Molex part supports an extended lower temperature limit (-40°C versus -35°C). All three connectors maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity.

Q: Are there packaging differences between these substitute parts?

A: The Molex 0530480410 is supplied in tray packaging. Packaging information for the Hirose variants is not specified in the provided data.

Q: Which substitute part should be selected for new designs?

A: The DF13-4P-1.25DS(55) is the recommended choice for new designs, as it maintains complete specification alignment with the obsolete DF13-4P-1.25DS(50) while offering active product status and established supply availability. The Molex 0530480410 is suitable where cross-platform standardization or extended temperature range operation is required.

Q: Do all three connectors meet RoHS compliance requirements?

A: Yes. The Hirose DF13-4P-1.25DS(50) and DF13-4P-1.25DS(55) are RoHS Compliant. The Molex 0530480410 is ROHS3 Compliant. All three meet current regulatory requirements.
