Molex 0050375183 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0050375183 is an 18-position rectangular connector receptacle housing with 0.098" (2.50mm) pitch, designed for free-hanging in-line applications using crimp termination and locking ramp fastening. This part is classified as obsolete, making identification of equivalent and substitute housings necessary for ongoing system support and new design implementations. The housing accommodates female socket contacts and operates within unlimited moisture sensitivity parameters.

Substitute Part Grouping Explanation

Substitution for the Molex 0050375183 is evaluated based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Connector type (receptacle)
• Contact type (female socket)
• Number of positions (18)
• Pitch specification (2.50mm or equivalent)
• Mounting type (free hanging in-line)
• Contact termination method (crimp)
• Fastening mechanism (locking ramp)

Identified Substitutes:

The TE Connectivity AMP Connectors part number 1-1375820-8 qualifies as a direct substitute. This part maintains the same 18-position count, receptacle configuration, female socket contact type, free-hanging in-line mounting, crimp termination, and locking ramp fastening. The pitch specification differs at 0.100" (2.54mm) versus the original 0.098" (2.50mm), representing a 0.02mm variance. This substitute is classified as active product status with RoHS compliance and operating temperature range of -55°C to 105°C.

The Molex part number 0026034082 is listed as a manufacturer-recommended substitute but does not meet substitution criteria. This part specifies 8 positions with 0.156" (3.96mm) pitch, friction lock fastening, and non-gendered contact type, making it incompatible with the original 18-position, 2.50mm pitch, locking ramp configuration.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the Molex 0050375183, the TE Connectivity AMP Connectors part number 1-1375820-8 is the qualified substitute. This part maintains active product status, ensuring ongoing availability and manufacturing support. Both the original and substitute parts are RoHS compliant and carry unlimited moisture sensitivity ratings, meeting regulatory and environmental requirements.

The pitch variance of 0.02mm (2.50mm to 2.54mm) represents a 0.8% dimensional difference. This specification change requires mechanical validation within the specific application context, particularly regarding PCB layout, contact alignment, and mating interface tolerances.

The Molex 0026034082 does not serve as a functional substitute due to incompatible position count (8 vs. 18), pitch specification (3.96mm vs. 2.50mm), and fastening mechanism (friction lock vs. locking ramp).

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1375820-8 directly replace the Molex 0050375183 without design modifications?

A: The TE Connectivity part maintains the same 18-position count, receptacle configuration, female socket contacts, and locking ramp fastening. The pitch difference of 0.02mm requires mechanical validation to confirm compatibility with existing PCB layouts and mating connectors. Contact alignment and tolerance stack-up analysis is necessary before implementation.

Q: Why is the Molex 0026034082 listed as a manufacturer recommendation but not a suitable substitute?

A: The 0026034082 differs in critical parameters: 8 positions instead of 18, 3.96mm pitch instead of 2.50mm, and friction lock fastening instead of locking ramp. These differences make it incompatible with applications designed for the 18-position, 2.50mm pitch configuration.

Q: What compliance certifications apply to the substitute part?

A: The TE Connectivity 1-1375820-8 is RoHS compliant with unlimited moisture sensitivity (MSL 1). Both the original and substitute parts meet the same regulatory compliance framework.

Q: Are the contact specifications identical between the original and substitute housings?

A: Both housings accommodate female socket contacts with crimp termination. Contact compatibility must be verified against the specific contact part numbers used in the original assembly, as housing and contact specifications are separate components.

Q: What is the operating temperature range for the substitute part?

A: The TE Connectivity 1-1375820-8 operates across -55°C to 105°C. This range encompasses typical industrial and commercial applications.
