Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance or RoHS compliance status, ensuring regulatory alignment and long-term availability compared to the obsolete HARTING 09643237802.

NorComp 182 Series Selection: The NorComp 182-025-113R series provides direct mechanical and electrical compatibility. Choose based on flange feature requirements:

182-025-113R161: Unthreaded housing flange with ground strap
182-025-113R171: 4-40 threaded housing flange with ground strap
182-025-113R181: 4-40 threaded mating-side female screwlock
182-025-113R431: Unthreaded housing flange without ground strap
182-025-113R451: 4-40 threaded housing flange without ground strap
182-025-113R531: 4-40 threaded housing flange with board lock feature

All NorComp variants operate at 5A, suitable for applications not requiring the original 7.5A rating.

TE Connectivity AMPLIMITE HD-20 Series Selection: The TE 5747842 series offers 6A current rating, closer to the original specification. Choose based on flange and feature requirements:

5747238-3: 4-40 threaded housing flange with ground strap
5747842-2: Unthreaded housing flange with board lock and ground strap
5747842-3: 4-40 threaded housing flange with board lock and ground strap
5747842-4: 4-40 threaded housing flange with board lock and ground strap

TE parts operate at 125V, acceptable for applications operating at or below this voltage.

Frequently Asked Questions (FAQ)

Q: Can NorComp 182-025-113R series parts directly replace the HARTING 09643237802?

A: Yes. All NorComp 182-025-113R variants maintain the same 25-position D-Sub plug configuration, right-angle solder termination, 3 (DB, B) shell size, and -55°C to 105°C operating temperature range. The primary difference is current rating: NorComp parts are rated at 5A versus the original 7.5A. Select the variant matching your flange and feature requirements.

Q: What is the difference between the NorComp and TE Connectivity substitute options?

A: NorComp 182 series parts are rated at 5A, while TE AMPLIMITE HD-20 series parts are rated at 6A. TE parts provide higher current capacity closer to the original specification. Both manufacturers offer variants with different flange configurations (threaded, unthreaded) and features (board lock, ground strap). Choose based on your specific mounting and current requirements.

Q: Are there compatibility concerns with shell finish differences (tin plated vs. nickel plated)?

A: No. Steel shells with tin or nickel plating are functionally equivalent for D-Sub connector applications. Both finishes provide corrosion resistance and electrical conductivity. Selection can be based on availability and cost considerations.

Q: Do the substitute parts support the same voltage rating as the original?

A: NorComp 182 series parts do not specify a voltage rating in the provided data. TE AMPLIMITE HD-20 series parts are rated at 125V, which is lower than the original 250V rating. For applications requiring 250V operation, verify that the NorComp parts meet your voltage requirements through the manufacturer, or select TE parts only if your application operates at 125V or below.

Q: What flange feature should I select?

A: Flange selection depends on your panel mounting method. Unthreaded flanges (182-025-113R161, 182-025-113R431, 5747842-2) use friction fit or adhesive mounting. 4-40 threaded flanges (182-025-113R171, 182-025-113R451, 182-025-113R531, 5747238-3, 5747842-3, 5747842-4) allow screw-based panel attachment. The original HARTING part featured a 4-40 threaded housing flange; select NorComp or TE variants with matching 4-40 flange configuration for direct replacement.

Q: Does the board lock feature affect compatibility?

A: Board lock is an optional feature that secures the connector to the PCB during assembly. The original HARTING 09643237802 includes board lock and filter features. NorComp 182-025-113R531 and all TE 5747842 variants include board lock. If board lock is required for your application, select these variants. Parts without board lock (182-025-113R161, 182-025-113R171, 182-025-113R181, 182-025-113R431, 182-025-113R451) are still mechanically compatible but lack this assembly feature.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed NorComp 182 series parts and TE 5747842-4 are ROHS3 compliant. TE 5747238-3, 5747842-2, and 5747842-3 are RoHS compliant. All parts meet regulatory requirements for lead-free manufacturing and hazardous substance restrictions.
