Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following core parameters: connector type (receptacle), contact type (female socket), number of positions (4), pitch (2.00mm), number of rows (1), mounting type (free hanging in-line), contact termination (crimp), and fastening type (latch holder). Variations in color, packaging format, insulation material composition, and operating temperature range do not prevent functional substitution when these core parameters remain constant.

The substitute parts are grouped into three categories:

Mini50 Series (0347910040, 0347910041, 0347910042, 0347910141): Identical base product number 034791 with core parameters matching the main part. Differences include housing color (Black, Gray, Brown) and packaging format (Bulk or Bag). All maintain PBT insulation and -40°C to 105°C operating range.

DuraClik 502351 Series (5023510400, 5023510401): Alternative series with identical core parameters. Insulation material remains PBT. Operating temperature -40°C to 105°C. Packaging in Bulk format.

DuraClik 505151 Series (5051510400, 5051510401): Alternative series with core parameters matching. Insulation material is Polyamide (PA), Nylon instead of PBT. Operating temperature extends to -40°C to 125°C. Packaging varies (Bulk or Bag).

DuraClik 560123 Series (5601230401, 5601230402): Alternative series with core parameters matching. Insulation material is PBT. Operating temperature extends to -40°C to 125°C or 130°C. Packaging varies (Tape & Reel or Bag).

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the main part 0347910043. Selection between Mini50 and DuraClik series depends on application requirements beyond the core connector parameters.

For applications requiring identical thermal performance (-40°C to 105°C), select from Mini50 34791 series (0347910040, 0347910041, 0347910042, 0347910141) or DuraClik 502351 series (5023510400, 5023510401). These maintain PBT insulation material and equivalent temperature ratings.

For applications requiring extended temperature operation to 125°C or 130°C, DuraClik 505151 series (5051510400, 5051510401) with Polyamide insulation or DuraClik 560123 series (5601230401, 5601230402) with PBT insulation are suitable. The 560123 series extends to 130°C maximum.

Packaging format selection (Bulk, Bag, or Tape & Reel) should align with procurement and assembly workflow requirements. DuraClik 502351 and 560123 series offer higher inventory availability, with 5023510400 providing 183094 units and 5601230401 providing 36515 units.

Frequently Asked Questions (FAQ)

Q: Can I substitute 0347910043 with a different color housing from the Mini50 series?

A: Yes. Parts 0347910040 (Black), 0347910041 (Gray), 0347910042 (Brown), and 0347910141 (Gray, Bag packaging) are functionally equivalent. All maintain identical connector type, position count, pitch, mounting configuration, and operating temperature range. Color variation does not affect electrical or mechanical compatibility.

Q: What is the difference between Mini50 and DuraClik series substitutes?

A: Both series maintain the core connector parameters (4-position, 2.00mm pitch, receptacle, female socket, crimp termination). Mini50 34791 series uses PBT insulation with -40°C to 105°C operating range. DuraClik 502351 series also uses PBT with identical temperature range. DuraClik 505151 uses Polyamide insulation with extended -40°C to 125°C range. DuraClik 560123 uses PBT with -40°C to 125°C or 130°C range. Series selection depends on thermal requirements and material compatibility with your application.

Q: Does packaging format affect connector compatibility?

A: No. Packaging format (Bulk, Bag, or Tape & Reel) affects procurement, storage, and assembly handling only. It does not alter the connector's electrical or mechanical properties. Select packaging based on your manufacturing process requirements.

Q: Can I use 5051510400 (Polyamide insulation) as a direct substitute for 0347910043 (PBT insulation)?

A: Functionally, yes, for the core connector parameters. However, insulation material differs. Polyamide offers extended temperature operation to 125°C versus PBT's 105°C. If your application operates within -40°C to 105°C, both materials are suitable. If thermal environment exceeds 105°C, Polyamide-based parts are required.

Q: Which substitute offers the highest inventory availability?

A: Part 5023510400 (DuraClik 502351 series, Natural color) provides 183094 units in stock, the highest availability among all listed substitutes. This part maintains PBT insulation and -40°C to 105°C operating range identical to the main part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status, matching the main part 0347910043. Regulatory compliance is maintained across all substitution options.
