Engineering Selection Recommendations

Direct NorComp Equivalent: The 172-009-212R021 is a direct manufacturer equivalent from NorComp Inc., differing only in packaging (tray vs. standard) and product status (obsolete). This part maintains identical electrical and mechanical specifications including 5A current rating, -50°C to 100°C operating range, and gold-flashed contact finish. Selection of this part is appropriate for applications requiring exact specification matching, though inventory status should be confirmed due to obsolete classification.

HARTING Cross-Manufacturer Substitutes (Active Status): HARTING D-Sub receptacles 09661116501, 09661116502, 09661117501, 09661117502, 09661516512, and 09661556512 provide active-status alternatives with enhanced current ratings (6.5A to 7.5A) and extended operating temperature ranges (-55°C to 125°C). These parts maintain the critical 9-position, Size 1 (DE, E) configuration with solder termination. Flange feature variations (M3 vs. 4-40 threaded) and contact form differences (stamped vs. machined) do not affect functional compatibility. Parts 09661556511 and 09661556512 include board lock features and gold contact finish, providing additional mechanical retention and corrosion resistance.

Mercury United Electronics Alternative: The 628-009-220-014 from Mercury United Electronics, Inc. offers a shielded variant with board guide features and nickel-plated shell finish. This part maintains 5A current rating and gold-flashed contact finish but operates within a reduced temperature range (-55°C to 85°C). Selection is appropriate for applications requiring shielding and board-level guidance.

Product Status Consideration: All HARTING and Mercury United Electronics parts maintain active product status, ensuring continued availability and supply chain stability. The NorComp 172-009-212R021 is classified as obsolete and should be selected only when exact NorComp specification compliance is mandated.

Frequently Asked Questions (FAQ)

Q: Can I substitute a HARTING part for the NorComp 172-009-212-021?

A: Yes. HARTING D-Sub receptacles 09661116501, 09661116502, 09661117501, 09661117502, 09661516512, 09661556511, and 09661556512 are functionally equivalent. All maintain the 9-position, Size 1 (DE, E) receptacle configuration with solder termination. Differences in current rating (6.5A vs. 5A), operating temperature range (-55°C to 125°C vs. -50°C to 100°C), and contact finish do not prevent substitution in standard applications. Flange design variations (M3 vs. 4-40 threaded) must be evaluated against your specific mounting requirements.

Q: What is the difference between the 09661117501 and 09661117502?

A: Both parts are HARTING 9-position D-Sub receptacles with identical electrical specifications (6.5A current rating, -55°C to 125°C operating range). The primary difference is flange feature: 09661117501 uses M3 housing/shell mounting, while 09661117502 uses 4-40 threaded board-side mounting. Selection depends on your panel or PCB mounting interface.

Q: Why do some substitute parts have higher current ratings?

A: HARTING parts (09661116501, 09661116502, 09661117501, 09661117502, 09661516512, 09661556511, 09661556512) are rated for 6.5A or 7.5A, compared to the main part's 5A rating. Higher current ratings indicate enhanced contact design and material composition. These parts remain fully compatible with applications designed for 5A operation, as they exceed the minimum requirement.

Q: Is the 628-009-220-014 shielded variant compatible?

A: The 628-009-220-014 is functionally compatible as a 9-position D-Sub receptacle with solder termination. It includes shielding and board guide features not present in the main part. However, its operating temperature range is limited to -55°C to 85°C (vs. -50°C to 100°C for the main part). Selection requires confirmation that your application does not exceed 85°C maximum operating temperature.

Q: What does "board lock" feature mean on parts 09661516512 and 09661556512?

A: Board lock is a mechanical retention feature that provides additional mechanical stability by locking the connector to the PCB or panel. This feature does not affect electrical compatibility but enhances mechanical robustness in high-vibration or high-stress environments. Parts without board lock (09661116501, 09661116502, 09661117501, 09661117502) remain fully compatible for standard applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts, including the main part 172-009-212-021, maintain ROHS3 compliance and UL94 V-0 flammability rating. This ensures regulatory compliance across all substitution options.

Q: What packaging options are available?

A: Substitute parts are available in bulk and tray packaging. The main part 172-009-212-021 is available in standard packaging (748 units in stock). The NorComp 172-009-212R021 is supplied in tray packaging. HARTING parts are available in both bulk and tray configurations. Mercury United Electronics 628-009-220-014 is supplied in bulk packaging. Packaging selection does not affect connector performance.
