Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 172-037-282-021 is determined by the following critical parameters:

• Connector Configuration: 37 positions, 2-row layout, shell size 4 (DC, C)
• Connector Type: Receptacle with female sockets
• Termination Method: Solder
• Mounting: Through-hole configuration
• Electrical Performance: Current rating and operating temperature range
• Compliance: RoHS and material flammability certification

Parts are grouped as direct equivalents when all critical parameters match. Parts are grouped as similar alternatives when mounting type, shell finish, or contact material differ but maintain functional compatibility within the 37-position D-Sub receptacle category.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Manufacturer)

172-037-283L021 from NorComp Inc. is a direct equivalent to 172-037-282-021. Both parts share identical electrical specifications, operating temperature range, RoHS3 compliance status, and shell material finish. The primary difference is packaging format (Tray vs. standard). This part is suitable for direct substitution with no design modifications required.

Compatible Alternatives (Amphenol ICC FCE17 Series)

FCE17C37SN280, FCE17C37SN2E0, FCE17C37SN480, and FCE17C37SN4D0 are compatible alternatives from Amphenol ICC. These parts maintain the 37-position receptacle configuration, 5A current rating, and gold contact finish. Differences include shell finish (tin-plated vs. nickel-plated) and operating temperature range (-40°C ~ 85°C vs. -50°C ~ 125°C). These parts are suitable for applications where the narrower temperature range is acceptable and tin-plated shell finish meets design requirements.

Extended Temperature Range Alternatives (Amphenol ICC SD Series)

L177SDCH37SOL2RM5G and L177SDCH37SOL2RM8G provide extended low-temperature operation (-55°C ~ 125°C). These parts feature board lock functionality and stamped contact form. Current rating is 3A, which is lower than the main part. These alternatives are suitable only for applications where the reduced current rating is acceptable and extended low-temperature performance is required.

Frequently Asked Questions (FAQ)

Q: Can FCE17C37SN280 replace 172-037-282-021 in all applications?

A: FCE17C37SN280 is mechanically and electrically compatible for most applications. However, verify that your application does not require operation below -40°C, as this part's minimum operating temperature is -40°C compared to -50°C for the original part. Shell finish difference (tin vs. nickel plating) does not affect electrical performance.

Q: What is the difference between 172-037-283L021 and 172-037-282-021?

A: Both parts are functionally identical. The primary difference is packaging: 172-037-283L021 is supplied in Tray packaging while 172-037-282-021 uses standard packaging. Electrical specifications, temperature range, and compliance certifications are identical.

Q: Can L177SDCH37SOL2RM5G be used as a direct replacement?

A: L177SDCH37SOL2RM5G is not a direct replacement due to reduced current rating (3A vs. 5A). Use this part only if your application current requirements do not exceed 3A. The extended temperature range (-55°C ~ 125°C) and board lock feature may be beneficial for specific applications.

Q: What is the difference between FCE17C37SN480 and FCE17C37SN2E0?

A: Both parts are from the Amphenol ICC FCE17 series with identical electrical specifications. The difference is in flange feature: FCE17C37SN480 has board-side flange (4-40), while FCE17C37SN2E0 has unthreaded housing/shell flange. Select based on your panel mounting requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part 172-037-282-021 is ROHS3 compliant. All listed substitute parts are RoHS compliant, meeting current environmental regulations.

Q: What does "Board Lock" feature mean in L177SDCH37SOL2RM8G?

A: Board Lock is a mechanical feature that provides additional retention of the connector to the PCB during mating and unmating cycles. This feature is present in the L177SDCH37 series but not in the NorComp 172 series or Amphenol FCE17 series.
