Amphenol ICC 65039-019LF Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 65039-019LF is an 18-position rectangular connector receptacle housing with 0.100" (2.54mm) pitch, designed for free-hanging in-line applications requiring crimp-style female socket termination. This Mini-PV™ series component operates across -40°C to 105°C and is manufactured from modified polyphenylene insulation material. The part is active in production with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct functional replacement in circuit designs.

Substitute Part Grouping Explanation

Substitute parts for the 65039-019LF are identified based on strict parametric equivalence across core electrical and mechanical characteristics. The primary substitution criteria are:

Critical Matching Parameters:

Connector type: Receptacle
Contact type: Female socket
Number of positions: 18
Pitch: 0.100" (2.54mm)
Number of rows: 1
Mounting type: Free hanging (in-line)
Contact termination: Crimp

Secondary Considerations:

Operating temperature range (must meet or exceed -40°C ~ 105°C minimum)
RoHS compliance status
MSL rating (1 = Unlimited)
Product status (Active)

Variations in insulation material, color, and series designation do not preclude substitution when all critical parameters align. The substitute parts listed maintain functional equivalence for connector housing applications requiring 18-position, single-row, 2.54mm pitch receptacle housings with crimp termination.

Engineering Selection Recommendations

All listed substitute parts maintain active production status with full compliance certifications. The 65039-019LF and Molex alternatives (0050579018, 0050579218, 0050579318) share identical operating temperature ranges (-40°C ~ 105°C) and RoHS compliance levels, making them directly interchangeable from a regulatory and thermal perspective.

The Amphenol ICC 65240-018LF offers an extended operating temperature range (-65°C ~ 125°C) and alternative insulation material composition, providing enhanced thermal performance for applications requiring operation beyond the standard -40°C ~ 105°C envelope. This part remains RoHS compliant with unlimited MSL rating.

Selection between Molex SL 70066 series variants (0050579018, 0050579218, 0050579318) depends on supply chain availability and inventory requirements, as all three parts are electrically and mechanically equivalent. Inventory levels range from 888 to 1265 pieces across these three part numbers.

Frequently Asked Questions (FAQ)

Q: Can the 65240-018LF substitute for the 65039-019LF in all applications?

A: The 65240-018LF is parametrically equivalent for all critical connector specifications (18 positions, 0.100" pitch, female socket receptacle, crimp termination). The primary difference is extended operating temperature range (-65°C ~ 125°C versus -40°C ~ 105°C) and alternative insulation material. It is suitable for applications within the original temperature range and provides additional thermal margin for higher-temperature environments.

Q: What is the difference between the three Molex part numbers (0050579018, 0050579218, 0050579318)?

A: These three Molex SL 70066 series parts are electrically and mechanically identical. All share the same 18-position, 0.100" pitch, female socket receptacle configuration with crimp termination. Differences exist only in internal part numbering or manufacturing lot designation. Selection can be based on inventory availability.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 65039-019LF and 65240-018LF are RoHS Compliant. The three Molex alternatives (0050579018, 0050579218, 0050579318) are ROHS3 Compliant. Both compliance levels meet current regulatory requirements for electronic component manufacturing.

Q: Do these connector housings include contacts?

A: No. All listed parts are connector housings only. Contacts are not included and must be sourced separately according to the specific application requirements and contact specifications.

Q: What is the significance of the MSL rating of 1 (Unlimited)?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. These parts can be stored and handled without special moisture control measures, simplifying inventory management and reducing handling costs.

Q: Can color differences affect substitution?

A: Color differences (black versus blue) do not affect electrical or mechanical function. The 65240-018LF blue housing is functionally equivalent to the black 65039-019LF. Color selection depends on application requirements, assembly documentation, or visual identification needs.
