Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (4), pitch (2.00mm), mounting type (free hanging in-line), contact termination (crimp), and fastening type (latch holder). Parts are grouped into two categories:

Category A - Mini50 34791 Series (Same Base Series): Parts 0347910040, 0347910042, 0347910043, and 0347910141 maintain identical electrical and mechanical specifications as the main part. Differences are limited to housing color and packaging format (bulk versus bag). All operate within -40°C to 105°C and use PBT insulation material.

Category B - DuraClik Series (Alternative Series): Parts 5023510400, 5023510401, 5051510400, 5051510401, 5601230401, and 5601230402 meet all core electrical and mechanical requirements but introduce variations in insulation material, operating temperature range, and series designation. DuraClik 502351 and 560123 parts maintain PBT insulation and -40°C to 125°C or -40°C to 130°C operating ranges. DuraClik 505151 parts use polyamide (PA) nylon insulation with -40°C to 125°C operating range.

Engineering Selection Recommendations

Mini50 34791 Series Substitutes (0347910040, 0347910042, 0347910043, 0347910141): These parts are direct functional equivalents with identical electrical specifications and operating temperature range. Selection among these parts depends on color coding requirements for circuit board identification and packaging format preference. All maintain ROHS3 compliance and MSL 1 rating. Part 0347910141 is packaged in bag format while others are bulk, which may affect procurement and assembly workflows.

DuraClik 502351 Series (5023510400, 5023510401): These parts provide equivalent functionality with extended inventory availability. Both maintain PBT insulation and -40°C to 105°C operating range, matching the main part's thermal specifications. Selection is based on color preference and bulk packaging availability.

DuraClik 505151 Series (5051510400, 5051510401): These parts use polyamide (PA) nylon insulation instead of PBT and support higher operating temperatures (-40°C to 125°C). Selection of these parts is appropriate only when the application requires enhanced thermal performance or nylon material properties. Packaging differs between bulk (5051510400) and bag (5051510401) formats.

DuraClik 560123 Series (5601230401, 5601230402): Part 5601230401 offers PBT insulation with -40°C to 125°C operating range in tape and reel packaging, suitable for automated assembly. Part 5601230402 extends the operating temperature to -40°C to 130°C with red housing color and bag packaging. MSL rating for 5601230402 is not applicable.

Frequently Asked Questions (FAQ)

Q: Can I substitute 0347910041 with any of the Mini50 34791 series parts? A: Yes. Parts 0347910040, 0347910042, 0347910043, and 0347910141 are electrically and mechanically equivalent. Differences are limited to housing color and packaging format. All operate within the same -40°C to 105°C temperature range and use identical PBT insulation material.

Q: What is the difference between bulk and bag packaging? A: Bulk packaging (0347910041, 0347910040, 0347910042, 0347910043) and bag packaging (0347910141) represent different distribution formats. Bag packaging may be preferred for smaller order quantities or specific assembly workflows. Both formats contain the same connector housing with identical specifications.

Q: Can I use DuraClik series parts as substitutes for Mini50 34791? A: DuraClik series parts (502351, 505151, 560123) meet all core electrical and mechanical requirements and are functionally compatible. However, they represent different product series with potential design variations. Selection should be based on application requirements, thermal performance needs, and material compatibility. DuraClik 505151 parts use polyamide insulation instead of PBT, which may affect chemical resistance and mechanical properties.

Q: What is the significance of the operating temperature range differences? A: Mini50 34791 and DuraClik 502351 parts operate from -40°C to 105°C. DuraClik 505151 and 560123 parts extend to -40°C to 125°C or -40°C to 130°C. Selection of higher-temperature-rated parts is necessary only when the application requires operation above 105°C. Standard Mini50 parts are sufficient for applications within -40°C to 105°C range.

Q: Why does 5601230402 have "Not Applicable" MSL rating? A: MSL (Moisture Sensitivity Level) rating is not applicable to this part based on the provided specifications. Consult Molex technical documentation for moisture handling requirements specific to this part number.

Q: What packaging format should I select for automated assembly? A: Tape and reel packaging (5601230401) is optimized for automated pick-and-place assembly. Bulk and bag formats are suitable for manual assembly or lower-volume applications.
