The following parts meet substitution criteria based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred for Drop-In Replacement):

172-E09-213R021 (NorComp Inc.) is the direct equivalent to 172-E09-212-021. Both parts share identical electrical and mechanical specifications, including 5A current rating, -50°C to 100°C operating temperature, ROHS3 compliance, and solder termination. This part is available in higher inventory (1803 pcs) and is packaged in trays for production environments.

Solder Termination Alternatives (Same Mounting and Termination):

628-009-220-047 (Mercury United Electronics) and 7-1393740-0 (TE Connectivity AMPLIMITE HD-20) are solder-terminated alternatives with identical connector geometry. Both maintain UL94 V-0 flammability rating and gold contact finish. The Mercury part supports -55°C to 85°C and includes board lock and shielding features. The TE Connectivity part supports extended temperature range and includes ground strap feature. Both are ROHS3 compliant and active products.

Extended Temperature Range Option:

8-1393483-7 (TE Connectivity AMPLIMITE HD-20) provides the widest operating temperature range (-55°C to 125°C) with solder termination and 3A current rating. This part is suitable for applications requiring thermal extremes beyond the original specification.

Press-Fit Termination Alternative:

5747091-2 (TE Connectivity AMPLIMITE HD-20) offers press-fit termination instead of solder, enabling automated assembly without thermal stress. This part supports -55°C to 105°C and is available in bulk packaging with highest inventory (3350 pcs).

Solder Paste Termination (Surface Mount Compatible):

D09S24A6RV22LF (Amphenol ICC Delta D series) provides solder paste termination with 5A per contact rating and includes board guide and pick-and-place cap features. This part is optimized for automated surface mount assembly and supports 300V voltage rating. Available in cut tape packaging with 1913 pcs in stock.

All listed substitutes maintain the critical 9-position, 2-row, DE/E shell size configuration and are active products with current RoHS compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can I substitute 172-E09-212-021 with a press-fit termination connector?

A: Yes. Part 5747091-2 (TE Connectivity) is a direct functional substitute with press-fit termination instead of solder. Press-fit termination eliminates soldering operations and reduces thermal stress on the PCB. All other electrical and mechanical parameters remain compatible. Verify your assembly process supports press-fit insertion tooling.

Q: What is the difference between the NorComp 172-E09-212-021 and 172-E09-213R021?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: 172-E09-212-021 is packaged in standard format, while 172-E09-213R021 is packaged in trays. The 172-E09-213R021 has higher inventory availability (1803 pcs vs. 802 pcs) and is preferred for production environments requiring tray-based component handling.

Q: Can I use the Mercury 628-009-220-047 in place of the NorComp part?

A: Yes, with one operational consideration. The Mercury part has a lower current rating (3A per contact vs. 5A) and a narrower operating temperature range (-55°C to 85°C vs. -50°C to 100°C). If your application requires the full 5A current capacity or operates above 85°C, this part is not suitable. The Mercury part includes board lock and shielding features not present in the original.

Q: Which substitute offers the widest operating temperature range?

A: The TE Connectivity 8-1393483-7 (AMPLIMITE HD-20 series) supports -55°C to 125°C, the widest range among all listed substitutes. This part is suitable for extreme thermal environments. Note that the current rating is 3A per contact, lower than the original 5A specification.

Q: Is the Amphenol D09S24A6RV22LF compatible with manual soldering?

A: The D09S24A6RV22LF is optimized for solder paste and automated reflow assembly. While the part can be manually soldered, it includes a pick-and-place cap and board guide designed for automated surface mount processes. For manual assembly, the standard solder-terminated alternatives (172-E09-213R021, 628-009-220-047, or 7-1393740-0) are more conventional choices.

Q: Do all substitutes meet RoHS compliance?

A: All listed substitutes are RoHS compliant. The NorComp, Mercury, and TE Connectivity 8-1393483-7 parts are ROHS3 compliant. The TE Connectivity 5747091-2 and Amphenol D09S24A6RV22LF are RoHS compliant. All parts are active products with current certifications suitable for regulated industries.

Q: What is the difference between tin-plated and nickel-plated shell finishes?

A: Both finishes provide corrosion protection and are electrically equivalent. Nickel plating (used in 172-E09-212-021, 172-E09-213R021, 628-009-220-047, and D09S24A6RV22LF) offers superior corrosion resistance in harsh environments. Tin plating (used in TE Connectivity parts 5747091-2, 7-1393740-0, and 8-1393483-7) is cost-effective and suitable for standard industrial applications. Selection depends on environmental exposure and cost requirements.

Q: Can I mix and match connectors from different manufacturers in the same assembly?

A: Yes. All listed substitutes maintain identical mating geometry (9-position, 2-row, DE/E shell size) and are mechanically and electrically interchangeable. However, for consistency in production, supply chain management, and warranty considerations, using parts from a single manufacturer or series is recommended.
