Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0850520593 is determined by strict alignment of the following critical parameters:

• Connector configuration: 48-position receptacle with female sockets
• Pitch and row arrangement: 0.100" (2.54mm) pitch across 3 rows in R/2 style
• Mounting and termination: Through-hole PCB mounting with right-angle orientation and solder termination
• Contact system: Gold-plated contacts for signal integrity
• Environmental compliance: Operating temperature range of -55°C to 125°C and UL94 V-0 flammability rating

The 3M DIN-048RSC-SR1-HM meets all these criteria, establishing it as a direct functional equivalent for applications requiring replacement or redesign of the obsolete Molex component.

Parameter Comparison

Engineering Selection Recommendations

The 3M DIN-048RSC-SR1-HM is the designated substitute for the obsolete Molex 0850520593. Selection of this alternative is supported by:

• Functional equivalence: Identical connector configuration, pitch, row arrangement, and mounting orientation
• Compliance alignment: Both components meet UL94 V-0 flammability requirements and maintain unlimited moisture sensitivity ratings
• Active product status: The 3M component is currently in active production, ensuring long-term availability and supply chain continuity
• Environmental specifications: Matching operating temperature range and contact finish specifications maintain system performance requirements

Frequently Asked Questions (FAQ)

Q: Can the 3M DIN-048RSC-SR1-HM be used as a direct replacement for the Molex 0850520593 in existing PCB designs?

A: Yes. Both components share identical pitch, row configuration, mounting type, and termination method. PCB footprints designed for the Molex part will accommodate the 3M substitute without modification.

Q: Are there differences in contact finish thickness between these parts?

A: Yes. The Molex component specifies 39.4µin (1.00µm) gold plating, while the 3M component specifies 3.00µin (0.076µm). Both thicknesses meet industry standards for gold-plated connector contacts and maintain electrical performance within the specified operating temperature range.

Q: What is the current rating for the 3M DIN-048RSC-SR1-HM?

A: The 3M component is rated for 3A per contact. The Molex original part does not specify a current rating in the provided data.

Q: Are both components RoHS compliant?

A: Yes. The Molex 0850520593 is ROHS3 compliant, and the 3M DIN-048RSC-SR1-HM is RoHS compliant. Both meet regulatory requirements for restricted substance elimination.

Q: What packaging options are available for the substitute part?

A: The 3M DIN-048RSC-SR1-HM is supplied in bulk packaging, with 1926 pieces currently in stock as new original inventory.
