Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub 37-position connectors is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Plug with male pins
• Number of positions: 37
• Number of rows: 2
• Shell size and layout: 4 (DC, C)
• Mounting type: Through hole, right angle
• Termination method: Solder
• Contact type: Signal

Allowable Variations:

• Flange feature design (mating-side screwlock versus housing/shell unthreaded)
• Shell material finish (tin plated versus yellow chromate plated)
• Contact finish thickness (within gold plating specifications)
• Current rating (7.5A primary; 5A acceptable for lower-power applications)
• Operating temperature range (primary -55°C ~ 125°C; substitute -50°C ~ 100°C acceptable for reduced thermal envelope)
• RoHS compliance status (compliant preferred; non-compliant acceptable for legacy systems)
• Product status (active preferred; obsolete acceptable for replacement inventory)

The four substitute parts listed maintain all mandatory matching parameters while accommodating variations in secondary characteristics based on manufacturing source and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: L717DC37PAVF (Amphenol ICC)

The L717DC37PAVF remains the preferred selection for new designs and applications requiring current compliance standards. This part carries Active product status, full RoHS compliance, and the highest current rating (7.5A) with the widest operating temperature range (-55°C ~ 125°C). The tin-plated steel shell and 8.00µin gold contact finish provide superior corrosion resistance and long-term reliability. Unlimited moisture sensitivity rating (MSL 1) eliminates storage and handling constraints.

Secondary Selection: M24308/24-28F (ITT Cannon, LLC)

The M24308/24-28F serves as the preferred substitute when L717DC37PAVF inventory is unavailable. This part maintains Active product status and matches the 7.5A current rating and extended operating temperature range (-55°C ~ 150°C). The 50.0µin gold contact finish exceeds the primary part specification. However, this part carries RoHS non-compliant status and requires REACH compliance verification. The housing/shell unthreaded flange feature differs from the primary part's mating-side screwlock design, necessitating mechanical interface assessment during integration.

Tertiary Selection: 174-E37-111R141 (NorComp Inc.)

The 174-E37-111R141 provides substitution capability for applications with reduced current requirements (5A maximum). This part maintains the mating-side female screwlock (4-40) flange feature matching the primary part. Obsolete product status and RoHS non-compliance restrict use to legacy system maintenance and replacement inventory scenarios. The narrower operating temperature range (-50°C ~ 100°C) limits thermal envelope compatibility.

Alternative Selection: 173-E37-111R141 (NorComp Inc.)

The 173-E37-111R141 offers substitution for legacy applications with panel-mount through-hole requirements. This part includes mounting brackets and maintains the mating-side screwlock flange feature. Obsolete status, RoHS non-compliance, and 5A current rating limit deployment to replacement and retrofit applications only. The 0.283" (7.20mm) backset spacing differs from the primary part's 0.319" (8.10mm) specification.

Restricted Selection: 174-E37-111R001 (NorComp Inc.)

The 174-E37-111R001 is suitable only for legacy system replacement where mechanical interface compatibility with housing/shell unthreaded flange design is confirmed. Obsolete status, RoHS non-compliance, and 5A current rating restrict use to maintenance scenarios. The 0.370" (9.40mm) backset spacing represents the largest deviation from the primary part specification.

Frequently Asked Questions (FAQ)

Q: Can the L717DC37PAVF be directly replaced with the M24308/24-28F?

A: Electrical and mechanical compatibility is confirmed for all mandatory parameters: 37-position, 2-row, shell size 4 (DC, C), through-hole right-angle solder termination. The M24308/24-28F maintains 7.5A current rating and exceeds the primary part's gold contact finish thickness. However, the housing/shell unthreaded flange feature differs from the L717DC37PAVF's mating-side female screwlock (4-40) design. Mechanical interface assessment is required to confirm compatibility with existing mating connectors and mounting structures.

Q: What is the impact of RoHS non-compliance in substitute parts?

A: RoHS non-compliant parts (173-E37-111R141, 174-E37-111R001, 174-E37-111R141, M24308/24-28F) contain restricted substances including lead and cadmium. These parts are suitable for applications not subject to RoHS regulations, legacy system maintenance, and replacement inventory where original specifications mandate non-compliant materials. New designs and applications subject to RoHS directives must use the L717DC37PAVF or equivalent RoHS-compliant alternatives.

Q: Are the NorComp parts (173-E37-111R141, 174-E37-111R001, 174-E37-111R141) suitable for new production?

A: No. All three NorComp substitute parts carry Obsolete product status. These parts are restricted to legacy system replacement, retrofit applications, and maintenance scenarios where original equipment specifications require NorComp connectors. New production designs must use the L717DC37PAVF (Active, RoHS compliant) or M24308/24-28F (Active, higher thermal rating) as primary selections.

Q: What is the significance of backset spacing differences?

A: Backset spacing defines the distance from the connector's rear face to the contact termination plane. The L717DC37PAVF specifies 0.319" (8.10mm); substitute parts vary: 173-E37-111R141 at 0.283" (7.20mm), 174-E37-111R001 and 174-E37-111R141 at 0.370" (9.40mm). These differences affect printed circuit board layout, panel cutout dimensions, and cable routing. Backset spacing must be confirmed compatible with existing mechanical interfaces before substitution.

Q: How do current rating differences affect substitution?

A: The L717DC37PAVF and M24308/24-28F both support 7.5A maximum current. The three NorComp substitute parts (173-E37-111R141, 174-E37-111R001, 174-E37-111R141) are rated for 5A maximum. Substitution with 5A-rated parts is acceptable only for applications where actual circuit current does not exceed 5A. Applications requiring 5A to 7.5A current capacity must use the L717DC37PAVF or M24308/24-28F.

Q: What operating temperature considerations apply to substitute selection?

A: The L717DC37PAVF operates across -55°C ~ 125°C. The M24308/24-28F extends to -55°C ~ 150°C, providing superior high-temperature performance. The three NorComp parts operate within -50°C ~ 100°C, a narrower envelope. Substitution with NorComp parts is acceptable only for applications where operating temperature remains within -50°C ~ 100°C. Applications requiring -55°C minimum or temperatures exceeding 100°C must use the L717DC37PAVF or M24308/24-28F.

Q: What is the difference between mating-side female screwlock and housing/shell unthreaded flange features?

A: The mating-side female screwlock (4-40) feature, present on the L717DC37PAVF, 173-E37-111R141, and 174-E37-111R141, provides threaded fastening to mating connectors using 4-40 screws. The housing/shell unthreaded flange feature, present on 174-E37-111R001 and M24308/24-28F, provides a flat mounting surface without threaded engagement. Flange feature compatibility must be confirmed with existing mating connectors and mechanical assemblies before substitution.

Q: Can substitute parts be mixed in the same assembly?

A: No. All connectors within a single assembly must maintain consistent flange feature design (either all mating-side screwlock or all housing/shell unthreaded) to ensure uniform mating interface compatibility. Mixing flange feature types within an assembly creates mechanical incompatibility and connection reliability issues.

Q: What packaging considerations apply to these substitute parts?

A: The L717DC37PAVF is supplied in Tray packaging (1056 pcs in stock). The M24308/24-28F is supplied in Bulk packaging (1409 pcs in stock). The NorComp parts are supplied in Tray packaging (693-764 pcs in stock). Packaging format affects inventory management, handling procedures, and component protection during storage and transportation. Packaging differences do not affect electrical or mechanical compatibility.
