DCMM37PAA101 37-Position D-Sub Plug Connector – Equivalent & Substitute Parts

Part Overview

The DCMM37PAA101 is a 37-position D-Sub plug connector manufactured by ITT Cannon, LLC, featuring right-angle solder termination and panel mount through-hole installation. This connector is classified as an active product and serves as a standard interface component in applications requiring multi-pin signal distribution with robust mechanical retention.

Substitute parts become necessary when the original manufacturer part is unavailable, when supply chain constraints require alternative sourcing, or when design flexibility permits equivalent configurations from other manufacturers. All substitute parts listed maintain functional equivalence within the electrical and mechanical parameters specified for this connector category.

Engineering Selection Recommendations

All substitute parts listed are active products from established manufacturers and maintain functional equivalence with the DCMM37PAA101 within the specified parameter tolerances.

For RoHS-compliant applications: Select from 174-E37-113R001, 182-037-113R171, 5747252-4, 5747843-3, 5747843-4, or 5747843-6. These parts carry ROHS3 or RoHS Compliant certification.

For applications requiring the original RoHS non-compliant specification: The DCMM37PAA101 remains the primary choice. If substitution is necessary, 747843-4 and 747843-6 maintain RoHS non-compliant status, though 747843-6 carries REACH Affected designation.

For maximum operating temperature retention: The DCMM37PAA101 supports -55°C to 150°C. Substitute parts support -55°C to 105°C or -50°C to 100°C, representing a reduced upper temperature limit. Applications requiring operation above 105°C must retain the original part.

For current rating considerations: The DCMM37PAA101 is rated at 7.5A. Substitute parts range from 5A to 6A. Applications requiring 7.5A continuous current must use the original part or confirm load requirements do not exceed substitute part ratings.

For mounting configuration: The DCMM37PAA101 specifies Panel Mount, Through Hole, Right Angle. Substitute parts specify Through Hole, Right Angle without explicit Panel Mount designation. Mechanical fit must be confirmed for panel-mounted applications.

For REACH compliance: Parts 174-E37-113R001, 182-037-113R171, 5747252-4, 5747843-2, 5747843-3, 5747843-4, and 5747843-6 carry REACH Unaffected status. Parts 747843-4 and 747843-6 carry REACH Affected designation.

Frequently Asked Questions (FAQ)

Q: Can I substitute a 5A-rated connector for the 7.5A DCMM37PAA101?

A: Substitution is permissible only if the application's actual current draw does not exceed the substitute part's rating. The 5A-rated 174-E37-113R001 and 182-037-113R171 are functionally equivalent for applications drawing 5A or less. For applications requiring 7.5A continuous current, the original DCMM37PAA101 or 6A-rated TE Connectivity parts (5747252-4, 5747843 series, 747843 series) must be used.

Q: What is the difference between the TE Connectivity 5747843 variants?

A: The 5747843 series differs in flange feature configuration: 5747843-2 features unthreaded housing, 5747843-3 and 5747843-4 feature 4-40 threaded housing, and 5747843-6 features mating-side female screwlock (4-40). All variants share identical electrical ratings, operating temperature, and contact specifications. Selection depends on mechanical mounting requirements.

Q: Why does the DCMM37PAA101 support -55°C to 150°C while substitutes support only -55°C to 105°C?

A: Operating temperature range is determined by dielectric material composition and contact design. The DCMM37PAA101 uses PCT dielectric material, which supports higher temperatures. Substitute parts use Polyamide (PA6T or PA9T) dielectric materials with lower thermal limits. Applications requiring operation above 105°C must retain the original part.

Q: Are NorComp and TE Connectivity substitutes interchangeable with the ITT Cannon original?

A: Yes, within the specified parameter tolerances. All substitute parts maintain 37-position D-Sub plug configuration, right-angle solder termination, 2-row layout, shell size 4 (DC, C), and UL94 V-0 flammability rating. Mechanical fit and electrical performance are equivalent. Verify flange feature compatibility with your specific mounting application.

Q: What does "REACH Affected" versus "REACH Unaffected" mean for connector selection?

A: REACH Affected status indicates the part may contain substances of very high concern (SVHC) listed under EU REACH regulations. REACH Unaffected status indicates compliance with REACH restrictions. For applications subject to EU regulations or requiring REACH compliance, select parts with REACH Unaffected designation: 174-E37-113R001, 182-037-113R171, 5747252-4, 5747843-2, 5747843-3, 5747843-4, or 5747843-6.

Q: Can I use a substitute part with different shell finish (Nickel or Tin instead of Yellow Chromate)?

A: Yes. Shell finish variation (Yellow Chromate Plated Cadmium, Nickel Plated, or Tin Plated) does not affect electrical or mechanical compatibility. Selection depends on environmental corrosion resistance requirements and application-specific specifications. Nickel-plated finishes (NorComp parts) and tin-plated finishes (TE Connectivity parts) provide equivalent protection in standard industrial environments.

Q: Is the DCMM37PAA101 still in production?

A: Yes, the DCMM37PAA101 is classified as an Active product with 1,147 units in stock. All substitute parts are also Active products with current inventory availability.
