Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 5019517010 is determined by the following critical parameters:

• Number of Positions: Must be 70 positions
• Pitch: Must be 0.020" (0.50mm)
• Mounting Type: Must be Surface Mount
• Voltage Rating: Must be 50V or higher
• Current Rating: Must support 0.4A per contact
• Locking Feature: Must include Flip Lock mechanism
• Contact Finish: Must be Gold
• Termination: Must be Solder

The substitute part Molex 5019517030 meets all critical electrical and mechanical parameters required for functional equivalence. Both parts share the same base product number (501951), pitch specification, position count, voltage and current ratings, locking mechanism, and contact finish. Differences in connector orientation (vertical vs. top), housing material composition, and actuator material do not prevent functional substitution when electrical and mechanical interface requirements are identical.

Parameter Comparison

Engineering Selection Recommendations

The Molex 5019517030 is the designated manufacturer substitute for the obsolete Molex 5019517010. Both connectors maintain identical electrical specifications (50V, 0.4A per contact) and mechanical interface requirements (70 positions, 0.50mm pitch, flip lock mechanism, solder termination).

The 5019517030 is currently in active production status with higher inventory availability compared to the obsolete 5019517010. Both parts carry equivalent compliance certifications: UL94 V-0 flammability rating, RoHS compliance, and REACH unaffected status. The substitute part supports an extended operating temperature range (-40°C to 85°C versus -25°C to 85°C), providing additional thermal margin for system applications.

The primary design difference is connector orientation (top-mounted versus vertical), which must be evaluated against specific PCB layout requirements. Height above board differs by 0.012" (0.31mm), which may require verification in space-constrained applications. Both parts utilize identical contact finish thickness and solder termination methods, ensuring compatibility with existing assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 5019517030 directly replace the 5019517010 in existing designs?

A: The 5019517030 meets all critical electrical and mechanical specifications of the 5019517010. However, the connector orientation difference (top-mounted versus vertical) requires PCB layout verification. The height above board difference of 0.012" (0.31mm) must be confirmed as acceptable for your application.

Q: What is the primary reason for substitution?

A: The Molex 5019517010 is obsolete. The 5019517030 is the manufacturer-designated equivalent part in active production, ensuring long-term component availability and supply chain continuity.

Q: Are the electrical ratings identical?

A: Yes. Both parts are rated for 50V and 0.4A per contact with identical contact finish thickness (3.94µin / 0.10µm) and solder termination specifications.

Q: What is the difference in operating temperature range?

A: The 5019517010 operates from -25°C to 85°C, while the 5019517030 operates from -40°C to 85°C. The substitute part provides extended low-temperature capability.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 5019517010 and 5019517030 are RoHS compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What packaging options are available?

A: The 5019517010 is supplied in Cut Tape (CT) and Digi-Reel packaging. The 5019517030 is supplied in Bulk packaging. Packaging format must be confirmed with your procurement requirements.

Q: Are the contact materials compatible?

A: The 5019517010 uses Copper Alloy contacts, while the 5019517030 uses Phosphor Bronze contacts. Both materials support identical gold finish thickness and current ratings, ensuring electrical compatibility.
