Molex 5010834010 Equivalent & Substitute Parts
Part Overview
The Molex 5010834010 is a 40-position receptacle connector with 0.016" (0.40mm) pitch, designed for surface mount applications in board-to-cable/wire configurations. This connector features gold-plated center strip contacts, solder termination, and detent lock fastening. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement planning.

Substitute Part Grouping Explanation
Substitution eligibility for the Molex 5010834010 is determined by strict alignment of the following critical parameters:
- Connector Type & Position Count: Must be a 40-position receptacle
- Pitch Specification: Mating pitch must be 0.016" (0.40mm) to ensure mechanical and electrical compatibility
- Mounting Technology: Surface mount configuration required
- Contact Finish: Gold plating on mating contacts
- Voltage & Current Ratings: Must meet or exceed 30V rating
- Termination Method: Solder termination required
- Flammability Compliance: UL94 V-0 rating mandatory
- Environmental Compliance: RoHS compliance required
The Hirose Electric DF36A-40S-0.4V(51) meets all critical substitution criteria and is classified as an active product with manufacturer recommendation.

Engineering Selection Recommendations
The Hirose DF36A-40S-0.4V(51) is the qualified substitute for the obsolete Molex 5010834010. Selection is based on:
- Product Status Alignment: The Hirose part is active and in production, ensuring long-term availability and supply chain continuity
- Compliance Certification: Both parts maintain UL94 V-0 flammability rating and RoHS compliance, meeting regulatory requirements
- Electrical Specifications: The Hirose part meets the 30V voltage requirement and maintains gold contact finish with increased thickness (12.0µin vs. 8.00µin), providing enhanced durability
- Operating Temperature: The Hirose part extends the upper temperature limit to 85°C, providing broader operational envelope
- Mechanical Compatibility: Both parts share identical 40-position, 0.016" pitch configuration with surface mount solder termination
The primary design consideration is the fastening mechanism difference: the Molex uses detent lock while the Hirose uses friction lock. This distinction requires mechanical validation in the specific application context.
Frequently Asked Questions (FAQ)
Q: Can the Hirose DF36A-40S-0.4V(51) directly replace the Molex 5010834010 in existing designs?
A: Direct mechanical and electrical substitution is supported based on matching connector type, position count, pitch, mounting method, and contact finish. The fastening mechanism differs (detent lock vs. friction lock), requiring mechanical fit validation in the specific application.
Q: What is the significance of the contact finish thickness difference?
A: The Hirose part features 12.0µin gold plating on mating contacts compared to 8.00µin on the Molex part. Increased thickness provides enhanced wear resistance and contact durability over the connector lifecycle.
Q: Are there temperature rating implications for substitution?
A: The Hirose part operates across -35°C to 85°C, extending the upper limit by 10°C compared to the Molex specification of -30°C to 75°C. Applications within the original Molex temperature range are fully supported.
Q: What packaging format is available for the Hirose substitute?
A: The Hirose DF36A-40S-0.4V(51) is supplied in Tape & Reel (TR) packaging, matching the original Molex part format for automated assembly compatibility.
Q: Are both parts halogen-free?
A: The Molex 5010834010 uses plastic and glass-filled insulation material. The Hirose DF36A-40S-0.4V(51) uses Liquid Crystal Polymer (LCP) with halogen-free composition, providing enhanced environmental compliance.
Q: What is the current rating for the Hirose substitute?
A: The Hirose part current rating varies by wire gauge, differing from the Molex specification of 0.2A per contact. Application-specific current requirements must be validated against wire gauge and termination method.
