Substitute Part Grouping Explanation

The Molex 0430451617 has one identified substitute part: 0430451619. Both parts belong to the Micro-Fit 3.0 43045 series and share identical specifications across all critical substitution parameters:

Matching Parameters (Substitution Basis):

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (16 positions, 2 rows)
• Mating pitch and row spacing (0.118" / 3.00mm)
• Mounting method (Surface Mount)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Electrical ratings (8A current, 600V voltage)
• Operating temperature range (-40°C ~ 105°C)
• Insulation material and flammability rating (LCP Glass Filled, UL94 V-0)
• Compliance certifications (ROHS3, REACH Unaffected)

Allowed Variation:

• Contact finish thickness on mating surface: 30.0µin (0.76µm) vs. 15.0µin (0.38µm)
• Features: Board Lock vs. Solder Retention

These variations do not affect mechanical or electrical compatibility in board-to-cable/wire applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0430451617 and 0430451619 are active production parts with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

Inventory Availability: The 0430451619 maintains higher stock levels (3131 pcs vs. 1141 pcs), making it preferable for high-volume procurement or extended lead-time mitigation.

Contact Finish Specification: The 0430451617 provides a thicker gold mating surface finish (30.0µin vs. 15.0µin). Applications requiring enhanced contact durability or corrosion resistance in harsh environments may benefit from the thicker finish specification.

Feature Set: The 0430451617 includes Board Lock functionality, while the 0430451619 features Solder Retention. Board Lock provides mechanical retention during assembly, whereas Solder Retention relies on solder joint integrity. Selection depends on assembly process requirements and mechanical retention strategy.

Both parts are suitable for automotive, industrial, medical, and telecommunications applications within the specified operating temperature range and electrical ratings.

Frequently Asked Questions (FAQ)

Q: Are the Molex 0430451617 and 0430451619 mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.118" / 3.00mm), row spacing, position count, shrouding configuration, and mounting type. They are mechanically interchangeable in board-to-cable/wire applications.

Q: What is the significance of the contact finish thickness difference?

A: The 0430451617 features a thicker gold mating surface (30.0µin vs. 15.0µin). Thicker finishes provide extended contact life and improved corrosion resistance in high-cycle mating applications or corrosive environments. Both finishes meet standard electrical performance requirements.

Q: Can I use the 0430451619 as a direct replacement for the 0430451617?

A: Yes, the 0430451619 is a direct substitute. Electrical ratings, operating temperature, insulation material, and compliance certifications are identical. The primary differences are contact finish thickness and retention feature type, neither of which affects electrical or mechanical compatibility.

Q: What is the difference between Board Lock and Solder Retention features?

A: Board Lock provides mechanical retention of the connector to the PCB during assembly and handling. Solder Retention relies on solder joint strength for mechanical stability. Selection depends on assembly process requirements and whether additional mechanical retention is necessary.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the 0430451617 and 0430451619 are rated for automotive applications and meet UL94 V-0 flammability requirements. Operating temperature range (-40°C ~ 105°C) and electrical ratings (8A, 600V) are suitable for standard automotive environments.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage, handling, or assembly.

Q: Are these parts RoHS compliant?

A: Yes. Both the 0430451617 and 0430451619 are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for EU and global markets.
