Key Parameters

Substitute Part Grouping Explanation

The Molex 5019514010 has one manufacturer-recommended substitute: 5019514030. Substitution eligibility is determined by the following critical parameters that must remain constant:

• Number of positions: 40
• Pitch: 0.020" (0.50mm)
• Mounting type: Surface Mount
• Connector orientation: Vertical - 1 Sided
• Locking mechanism: Flip Lock
• Termination method: Solder
• Housing material: Liquid Crystal Polymer (LCP), Glass Filled
• Flammability rating: UL94 V-0

The substitute part 5019514030 maintains all critical mechanical and electrical interface parameters, enabling direct functional replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The Molex 5019514030 is the manufacturer-recommended substitute for the obsolete 5019514010. Both parts maintain identical mechanical interfaces and core electrical specifications, ensuring PCB-level compatibility without design modification.

The 5019514030 offers enhanced specifications in three areas: increased current rating (0.5A versus 0.4A), extended low-temperature operating range (-40°C versus -25°C), and active product status with ongoing manufacturer support. The substitute uses phosphor bronze contacts instead of copper alloy, maintaining gold plating and electrical performance.

Both parts carry equivalent compliance certifications: UL94 V-0 flammability rating and REACH unaffected status. The 5019514030 carries RoHS compliance designation, supporting modern supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5019514030 be used as a direct replacement for the 5019514010 without PCB modification?

A: Yes. Both connectors share identical pitch (0.5mm), position count (40), mounting type (surface mount), and height above board (4.04mm). No PCB layout changes are required.

Q: What is the difference in current rating between these parts?

A: The 5019514010 is rated for 0.4A continuous current, while the 5019514030 is rated for 0.5A. The substitute part supports higher current applications within the same 50V voltage envelope.

Q: Does the operating temperature range difference affect compatibility?

A: The 5019514030 extends the low-temperature limit to -40°C compared to the 5019514010's -25°C minimum. Both maintain the same 85°C upper limit. Applications operating above -25°C experience no functional difference.

Q: Are there packaging differences between these parts?

A: The 5019514010 was supplied in unspecified packaging, while the 5019514030 is available in bulk packaging. Consult with the supplier regarding minimum order quantities and packaging configurations.

Q: Why is the 5019514010 classified as obsolete?

A: The 5019514010 has been superseded by the 5019514030 within the Easy-On 501951 series. The manufacturer recommends transitioning to the active substitute part for new designs and ongoing production.

Q: Are compliance certifications equivalent between these parts?

A: Both parts meet UL94 V-0 flammability requirements and REACH unaffected status. The 5019514030 carries explicit RoHS compliance designation, while the 5019514010 carries ROHS3 compliance. Both satisfy modern regulatory requirements.
