HARTING 09185205321 Equivalent & Substitute Parts

Part Overview

The HARTING 09185205321 is a rectangular connector header with right-angle mounting, 20 positions, and 2.54mm pitch spacing. This through-hole component features shrouded 4-wall design with solder termination and latch holder fastening. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. Active alternatives from major manufacturers including Molex, TE Connectivity, 3M, and Amphenol ICC provide direct functional equivalents with maintained electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following core parameters:

Critical Matching Parameters:

Connector Type: Header
Contact Type: Male Pin
Number of Positions: 20
Number of Rows: 2
Pitch - Mating: 0.100" (2.54mm)
Row Spacing - Mating: 0.100" (2.54mm)
Mounting Type: Through Hole, Right Angle

Engineering Selection Recommendations

Primary Recommendation - ROHS3 Compliant, REACH Unaffected:

Molex 0702472054 and Molex 0702472052 represent the most direct functional equivalents with active product status, ROHS3 compliance, and REACH unaffected classification. Both parts maintain identical core electrical and mechanical specifications. The 0702472054 variant offers higher inventory availability (6766 units) in tray packaging, while 0702472052 provides bulk packaging (1126 units). These Molex C-Grid 70247 series connectors feature push-pull fastening in place of the original latch holder design, a secondary parameter variation that does not affect mating interface compatibility.

Secondary Recommendation - Extended Temperature Range:

TE Connectivity 2-1761605-7 provides ROHS3 compliance with REACH unaffected status and includes specified voltage rating (250VAC) and current rating (1A per contact). This AMP-Latch series part operates across -65°C to 105°C, narrower than the original -55°C to 125°C specification but suitable for most industrial applications. Bulk packaging provides 4791 units in stock.

Alternative Options - RoHS Compliant:

3M 30320-5002HB (303 series) maintains RoHS compliance with REACH unaffected status and active product status. This part features brass contact material and flash gold finish on both mating and post surfaces. Operating temperature range is -55°C to 105°C with 1A current rating.

Compliance-Restricted Alternatives:

TE Connectivity 103310-5, 103311-5, 5103310-5, and 5103311-5 are functionally equivalent but carry RoHS non-compliant or REACH affected designations. These parts are suitable only for applications where legacy component specifications are required or regulatory restrictions do not apply. Amphenol ICC 69155-020 and 75867-104LF similarly carry REACH affected status and are appropriate only for non-restricted applications.

Frequently Asked Questions (FAQ)

Q: Can Molex 0702472054 directly replace HARTING 09185205321 on existing PCBs?

A: Yes. Both parts maintain identical mating pitch (0.100" / 2.54mm), position count (20), row configuration (2 rows), and through-hole right-angle mounting. The push-pull fastening mechanism on the Molex part replaces the original latch holder design, but this does not affect PCB footprint or mating interface compatibility.

Q: What is the difference between Molex 0702472052 and 0702472054?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: 0702472052 ships in bulk, while 0702472054 ships in tray format. Inventory levels also differ (1126 units bulk versus 6766 units tray). Select based on assembly process requirements and available stock.

Q: Are TE Connectivity AMP-Latch series parts (103310-5, 103311-5, 5103310-5, 5103311-5) suitable for new designs?

A: These parts are functionally compatible but carry RoHS non-compliant or REACH affected designations. For new designs subject to RoHS3 or REACH compliance requirements, Molex or TE Connectivity 2-1761605-7 are preferred. For legacy or non-restricted applications, AMP-Latch variants are acceptable.

Q: What is the significance of contact finish thickness variations?

A: Contact finish thickness affects durability and wear resistance. The original HARTING part specifies 30.0µin (0.76µm) mating finish. Molex 0702472054 provides 5.00µin (0.127µm), while TE Connectivity 103310-5 and 5103310-5 provide 15.0µin (0.38µm). These variations do not preclude substitution but may influence long-term contact reliability in high-cycle mating applications.

Q: Does the 3M 30320-5002HB operate within the original temperature range?

A: The 3M part operates from -55°C to 105°C, matching the lower bound of the original -55°C to 125°C specification but not the upper limit. This is suitable for most industrial and commercial applications but may not be appropriate for high-temperature environments exceeding 105°C.

Q: Which substitute part offers the best inventory availability?

A: TE Connectivity 5103311-5 provides the highest inventory level at 9485 units in tube packaging. Molex 0702472054 offers 6766 units in tray packaging. Both are suitable for high-volume production requirements.

Q: Are there contact material differences between substitute parts?

A: Yes. The original HARTING part uses copper alloy contacts. Molex parts use phosphor bronze, TE Connectivity parts use brass or phosphor bronze, 3M uses brass, and Amphenol ICC uses phosphor bronze. These material variations do not affect electrical performance for standard signal applications but may influence contact resistance characteristics in high-current or high-frequency applications.
