Molex 5036601010 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 5036601010 is a Micro-Lock 503660 series rectangular connector header designed for through-hole, right-angle board-to-cable/wire applications. This connector features a 10-position, single-row configuration with 0.079" (2.00mm) pitch and shrouded 4-wall design. The part is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 5036601010 is determined by the following critical parameters that must align between the original and substitute component:

Mandatory Matching Parameters:

• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 10
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Shrouding: Shrouded - 4 Wall
• Style: Board to Cable/Wire
• Contact Material: Brass
• Contact Finish: Tin
• RoHS Status: ROHS3 Compliant
• Material Flammability Rating: UL94 V-0

The Molex 5055781070 qualifies as a substitute based on these parameters. While the mounting type differs (Surface Mount vs. Through Hole), the electrical and mechanical interface characteristics remain compatible for applications where PCB mounting method can be adapted. The substitute maintains identical pitch, position count, contact configuration, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 5055781070 is the designated substitute for the obsolete 5036601010. Selection of this substitute is supported by the following factors:

Product Status: The 5055781070 maintains active product status, ensuring ongoing availability and manufacturing support. The original 5036601010 is obsolete, necessitating substitution for new procurements and system continuity.

Compliance Certifications: Both components maintain ROHS3 compliance and UL94 V-0 material flammability rating, meeting regulatory and safety requirements for equivalent applications.

Electrical and Mechanical Compatibility: The substitute maintains identical mating pitch (0.079"), position count (10), row configuration (1), contact material (Brass), and contact finish (Tin). These parameters ensure mechanical interchangeability with mating connectors designed for the original component.

Series Continuity: Both components are Molex Micro-Lock family products, representing an evolutionary upgrade from the 503660 series to the 505578 PLUS series.

Mounting Consideration: The primary difference is mounting method (Surface Mount vs. Through Hole). PCB design adaptation is required to accommodate this change. The substitute's surface mount configuration may offer advantages in high-density applications and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 5055781070 directly replace the 5036601010 without PCB redesign?

A: Direct replacement without PCB modification is not possible due to different mounting types. The original uses through-hole mounting with kinked pins, while the substitute uses surface mount termination. PCB footprint redesign is required.

Q: Are the mating connectors compatible between these two parts?

A: Yes. Both components maintain identical mating pitch (0.079"), position count (10), and shrouding configuration. Mating connectors designed for the 5036601010 will interface correctly with the 5055781070.

Q: What is the difference in insulation material between these connectors?

A: The original uses Polybutylene Terephthalate (PBT) with glass filling, while the substitute uses Polyamide (PA) Nylon. Both materials meet UL94 V-0 flammability requirements and are suitable for general industrial applications.

Q: Does the substitute provide operating temperature specifications?

A: Yes. The 5055781070 specifies an operating temperature range of -40°C to 105°C. The original part does not provide this specification in available documentation.

Q: Are both components RoHS compliant?

A: Yes. Both the 5036601010 and 5055781070 are ROHS3 compliant and meet environmental regulatory requirements.

Q: What is the voltage rating for the substitute?

A: The 5055781070 is rated for 250VAC/DC. The original part does not specify a voltage rating in available documentation.

Q: Is the insulation height difference significant?

A: The insulation height difference is minimal (0.236" vs. 0.232", a 0.004" variance). This difference is within typical manufacturing tolerances and does not affect functional compatibility.
