Parameter Comparison

Engineering Selection Recommendations

L177DFEH09SAM4 (Amphenol ICC): Select this part as the primary choice when maximum current capacity (7.5A) and extended operating temperature range (-55°C to 125°C) are required. This part maintains active product status with full RoHS compliance and unlimited moisture sensitivity level (MSL 1), making it suitable for long-term storage and deployment in diverse environmental conditions.

182-009-213R531 (NorComp Inc.): This substitute is suitable for applications where current requirements do not exceed 5A and operating temperatures remain within -55°C to 105°C. The part carries ROHS3 compliance and features board lock functionality. Backset spacing tolerance (0.318") is within acceptable mechanical variation. Select this option when supply availability of the primary part is constrained and application parameters permit the reduced current rating.

5745395-3 (TE Connectivity AMPLIMITE HD-20): This substitute accommodates current requirements up to 6A within the -55°C to 105°C operating range. The part features mating side female screwlock (4-40) and phosphor bronze contact material. RoHS compliance and unlimited MSL rating are maintained. The AMPLIMITE HD-20 series designation indicates enhanced mechanical durability. Select this option when the 6A current rating satisfies application demands and the screwlock feature provides additional mechanical security benefits.

All three parts maintain UL94 V-0 flammability rating, gold contact finish, and D-Sub 9-position receptacle configuration with solder termination. Selection between substitutes depends on specific application current, temperature, and mechanical retention requirements.

Frequently Asked Questions (FAQ)

Q: Can the 182-009-213R531 be used in place of the L177DFEH09SAM4 in a 7.5A circuit?

A: No. The 182-009-213R531 has a maximum current rating of 5A, which is insufficient for circuits requiring 7.5A. Using this part in a 7.5A application would exceed its electrical specifications and create reliability risks.

Q: What is the significance of the backset spacing difference between 0.319" and 0.318"?

A: The backset spacing difference of 0.001" (0.025mm) is within standard mechanical tolerance for D-Sub connectors and does not affect functional compatibility. Both measurements fall within acceptable manufacturing variation for this connector category.

Q: Are there temperature limitations when substituting the L177DFEH09SAM4 with the 5745395-3?

A: Yes. The 5745395-3 operates within -55°C to 105°C, while the L177DFEH09SAM4 extends to 125°C. Applications requiring sustained operation above 105°C must use the primary part or verify that the substitute's reduced upper temperature limit is acceptable for the specific use case.

Q: What is the difference between tin plating and nickel plating on the shell material?

A: Both finishes provide corrosion resistance on steel shells. Tin plating (L177DFEH09SAM4) offers excellent solderability and lower contact resistance. Nickel plating (182-009-213R531) provides enhanced corrosion resistance in harsh environments. Selection depends on environmental exposure and soldering process requirements.

Q: Does the flash gold contact finish on the 182-009-213R531 provide equivalent performance to the 30.0µin thickness on other parts?

A: Flash gold finish provides minimal gold plating thickness for contact protection and corrosion resistance. The 30.0µin (0.76µm) thickness on the L177DFEH09SAM4 and 5745395-3 offers greater durability for high-cycle mating applications. Flash finish is suitable for applications with lower mating cycle requirements.

Q: What does the board lock feature on the 182-009-213R531 provide?

A: Board lock is a mechanical retention feature that secures the connector to the printed circuit board during assembly and operation, preventing accidental disconnection. This feature is not present on the other two parts and may be beneficial in vibration-prone environments.

Q: Are all three parts suitable for RoHS-restricted applications?

A: Yes. The L177DFEH09SAM4 and 5745395-3 carry RoHS Compliant status. The 182-009-213R531 carries ROHS3 Compliant status. All three parts meet RoHS requirements for restricted substance elimination and are suitable for RoHS-regulated applications.

Q: What packaging considerations should be evaluated when selecting a substitute?

A: The L177DFEH09SAM4 and 182-009-213R531 are supplied in trays, while the 5745395-3 is supplied in tubes. Tray packaging typically facilitates automated assembly processes, while tube packaging may require manual handling. Verify compatibility with receiving, storage, and assembly equipment before finalizing part selection.

Q: Can the 5745395-3 be used in applications requiring 300V rating?

A: The 5745395-3 has a voltage rating of 125V, which is below the 300V rating of the L177DFEH09SAM4. Applications requiring 300V operation must use the primary part or verify that the substitute's 125V rating is adequate for the specific circuit voltage.
