Engineering Selection Recommendations

All five NorComp substitute parts maintain active product status and ROHS3 compliance, ensuring continued manufacturing support and regulatory alignment with the original HARTING 09663556512 specification.

The primary design consideration when selecting among substitute options is the flange feature configuration:

171-025-213R001 provides an unthreaded housing/shell flange, suitable for applications requiring standard panel mounting without threaded fastener engagement.

171-025-213R011 and 171-025-213R021 feature board-side 4-40 threaded flanges, appropriate for PCB-mounted applications with mechanical retention through board-side fastening. These parts differ only in inventory availability (905 units versus 4026 units respectively).

171-025-213R031 incorporates a mating-side 4-40 threaded flange, designed for connector-to-connector mechanical coupling and retention at the mating interface.

171-025-213R911 combines board-side 4-40 threaded flange with mating-side female screwlock capability and includes board lock functionality, matching the original part's board lock feature and providing dual mechanical retention options.

All substitute parts operate within -50°C to 100°C temperature range and carry 5A current rating. Applications requiring the full -55°C to 125°C operating range or 6.5A current capacity of the original HARTING part should evaluate these thermal and electrical constraints against specific system requirements.

Frequently Asked Questions (FAQ)

Q: Can NorComp 171-025-213R series connectors directly replace HARTING 09663556512 in existing PCB designs?

A: Yes, all five NorComp substitute parts maintain identical 25-position DB-3 shell configuration, solder termination, and signal contact specifications. Panel mount capability in NorComp parts provides additional mounting flexibility. Verify flange feature compatibility with your specific mounting configuration (housing/shell, board-side, or mating-side threaded engagement).

Q: What is the significance of the different flange features (Housing/Shell, Board Side, Mating Side)?

A: Flange features determine mechanical mounting and retention method. Housing/shell flanges (171-025-213R001) mount to panel cutouts. Board-side flanges (171-025-213R011, 171-025-213R021) secure to PCB surfaces via threaded fasteners. Mating-side flanges (171-025-213R031) engage with mating connector hardware. The 171-025-213R911 provides both board-side and mating-side options with board lock, matching the original part's board lock capability.

Q: Are there current rating implications when substituting from 6.5A to 5A?

A: The 5A rating of NorComp substitutes represents a conservative specification. Applications operating at or below 5A per contact experience no functional limitation. Designs requiring the full 6.5A capacity should retain the original HARTING specification or consult with NorComp regarding higher-current variants.

Q: How do operating temperature ranges affect part selection?

A: The original HARTING part operates -55°C to 125°C; NorComp substitutes operate -50°C to 100°C. Applications within the -50°C to 100°C envelope are fully compatible. Systems requiring extended low-temperature operation below -50°C or high-temperature operation above 100°C should retain the original HARTING specification.

Q: What packaging differences exist between HARTING and NorComp options?

A: HARTING 09663556512 ships in bulk packaging; all NorComp substitutes ship in tray packaging. Tray packaging provides improved component protection and handling efficiency in manufacturing environments. No functional or electrical differences result from packaging variation.

Q: Which NorComp part best matches the original HARTING 09663556512 feature set?

A: NorComp 171-025-213R911 most closely aligns with the original specification, incorporating board lock functionality and dual mechanical retention (board-side and mating-side threaded flanges). This part maintains the board lock feature present in the HARTING original while providing enhanced mounting flexibility.
