Substitute Part Grouping Explanation

Substitution for the HARTING 09185345321 is determined by strict alignment of the following critical parameters:

34-position, 2-row configuration at 0.100" (2.54mm) pitch
Right-angle, through-hole mounting
Shrouded 4-wall design with male pin contacts
Solder termination with square contact geometry
UL94 V-0 flammability rating
ROHS3 compliance and MSL 1 rating

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in contact material, contact finish thickness, insulation material, and fastening mechanism (push-pull vs. latch holder) are permitted within the substitution scope, as these do not affect mating compatibility or board-level integration.

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing support, addressing the obsolescence of the HARTING 09185345321. Selection among substitutes should be based on the following criteria:

Primary Recommendation: 3-1761605-1 (TE Connectivity) This part offers the highest inventory availability (2998 units) and maintains full ROHS3 compliance with rated electrical specifications (1A per contact, 250VAC). Operating temperature range of -65°C to 105°C covers the original part's lower bound while providing extended upper-temperature margin for thermal design flexibility.

Secondary Recommendation: 0702473451 (Molex C-Grid 70247) Active status with 700 units in stock. ROHS3 compliant with push-pull fastening mechanism. Suitable for applications requiring automotive, medical, and telecommunications certifications.

Alternative Options: TE Connectivity 103310-7, 103311-7, 5103310-7, 5103311-7 These variants provide packaging flexibility (bulk, tray, tube) and are available in quantities ranging from 734 to 7288 units. Note that 103310-7 and 103311-7 carry "Not applicable" RoHS status and "REACH Affected" designation, requiring compliance verification for regulated applications.

Amphenol ICC Quickie™ Series: 75867-106LF, 75867-306LF Active products with 1425 and 803 units respectively. RoHS compliant with GXT™ gold plating. Suitable for applications where Amphenol qualification is required.

3M D2534-5002-AR Active product with 1749 units. ROHS3 compliant with 1.75A current rating per contact, providing higher current capacity than standard 1A alternatives. Operating temperature -55°C to 105°C matches the original part's lower specification.

Frequently Asked Questions (FAQ)

Q: Can I directly replace HARTING 09185345321 with any of these substitutes? A: Yes. All listed substitutes maintain the critical mating parameters: 34 positions, 2 rows, 0.100" (2.54mm) pitch, right-angle through-hole mounting, shrouded 4-wall design, and solder termination. Mechanical and electrical compatibility is assured at the board interface level.

Q: What is the difference between push-pull and latch holder fastening? A: The original HARTING part uses latch holder fastening. Most substitutes employ push-pull mechanisms. Both provide secure mating; the fastening type affects connector engagement/disengagement force and procedure but does not impact electrical performance or board-level integration.

Q: Are there temperature rating differences I should consider? A: The original HARTING part operates from -55°C to 125°C. Most substitutes operate from -65°C to 105°C, providing lower-temperature margin but reduced upper-temperature capability. For applications requiring operation above 105°C, verify thermal design margins or consult manufacturer datasheets for extended-temperature variants.

Q: What does ROHS3 compliance mean for my application? A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All primary recommendations carry ROHS3 status. Parts marked "Not applicable" (103310-7, 103311-7) may contain lead-based finishes and require compliance verification for regulated markets.

Q: Does packaging type (bulk, tray, tube) affect electrical performance? A: No. Packaging affects handling, storage, and logistics only. Electrical and mechanical specifications remain identical across packaging variants. Select based on procurement volume and handling requirements.

Q: Which substitute offers the best current rating? A: The 3M D2534-5002-AR provides 1.75A per contact, compared to 1A per contact for TE Connectivity and Molex alternatives. Select based on circuit current requirements.

Q: Are all substitutes REACH compliant? A: Most substitutes carry "REACH Unaffected" or "Vendor Undefined" status. TE Connectivity parts 103310-7 and 103311-7 are marked "REACH Affected," requiring compliance verification for European Union applications. Confirm REACH status with your supplier for regulated markets.
