TE Connectivity 5745441-4 D-Sub Receptacle 37-Position Equivalent & Substitute Parts

Part Overview

The TE Connectivity 5745441-4 is a 37-position D-Sub receptacle connector with female sockets, right-angle solder termination, and through-hole mounting. This connector belongs to the AMPLIMITE HDP-20 series and is classified as an active product with full RoHS compliance. The connector features a steel tin-plated shell, gold-plated phosphor bronze contacts, and operates across a temperature range of -55°C to 105°C with a 6A current rating at 125V.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when design flexibility permits selection from multiple qualified manufacturers meeting the same electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The Amphenol ICC Delta D series connectors (D37S13A4GL00LF, D37S13A4GV00LF, D37S13A4PV00LF) provide direct functional equivalence to the TE Connectivity 5745441-4. These parts maintain identical 37-position configuration, through-hole right-angle mounting, solder termination, and UL94 V-0 flammability rating. The Delta D series offers enhanced voltage rating (300V versus 125V) and extended operating temperature range (-55°C to 125°C versus -55°C to 105°C), providing superior performance margins. All three variants are RoHS compliant with active product status.

Secondary Substitutes (Acceptable with Design Verification):

The HARTING 09664526613 connector maintains critical electrical and mechanical parameters with 6.5A current rating and extended temperature range to 125°C. This part is ROHS3 compliant and active. The NorComp 183 series (183-037-213R171 and 183-037-213R541) provide panel mount capability in addition to through-hole mounting, with ROHS3 compliance and active status. Current rating is 5A, which is within acceptable range for most applications.

Limited Substitutes (Application-Specific Only):

The Amphenol ICC SD series connectors (L77SDC37S1ACH3R, L77SDC37SA4CH4F, L77SDC37SA4CH4FC309) and Mercury United Electronics 626-037-262-012 are suitable only for applications where 3A per-contact current rating is sufficient. The Mercury part additionally operates to only 85°C maximum temperature, limiting its use to lower-temperature environments. These parts maintain UL94 V-0 compliance and active product status.

All listed substitutes carry equivalent or superior regulatory compliance (RoHS, REACH, EAR99) and maintain active product status.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5745441-4 be directly replaced with any of the listed substitute parts?

A: Direct replacement depends on application current and voltage requirements. The Amphenol ICC Delta D series (D37S13A4GL00LF, D37S13A4GV00LF, D37S13A4PV00LF) provides full functional equivalence with superior electrical ratings. The HARTING 09664526613 and NorComp 183 series are compatible for applications requiring 5-6.5A. The Amphenol ICC SD series and Mercury 626-037-262-012 are limited to 3A applications.

Q: What is the significance of backset spacing differences among these connectors?

A: Backset spacing defines the distance from the mating face to the solder tail termination points. The TE Connectivity 5745441-4 specifies 0.454" (11.53mm). Substitute parts exhibit variations: HARTING 09664526613 at 0.409" (10.40mm), NorComp 183 series at 0.590" (14.99mm), Mercury 626-037-262-012 at 0.584" (14.84mm), and Amphenol ICC parts ranging from 0.318" to 0.409". These differences affect PCB layout and mounting hole positioning. Backset spacing must be verified against specific board design requirements before substitution.

Q: Are all substitute parts RoHS compliant?

A: Yes. The TE Connectivity 5745441-4 is RoHS compliant. All listed substitutes are either RoHS compliant or ROHS3 compliant, meeting or exceeding the regulatory requirement. ROHS3 designation indicates compliance with the most current RoHS directive revision.

Q: What packaging formats are available?

A: The TE Connectivity 5745441-4 is supplied in bulk packaging. Substitute parts are available in both bulk (TE Connectivity 5745441-4, Mercury 626-037-262-012) and tray packaging (HARTING 09664526613, NorComp 183 series, Amphenol ICC Delta D and SD series). Packaging selection affects inventory management and component handling procedures.

Q: How do shell finish options affect connector performance?

A: The TE Connectivity 5745441-4 features steel with tin plating. Substitute parts offer tin plating, nickel plating, or tin-nickel plating. Tin plating provides standard corrosion resistance. Nickel plating (NorComp 183 series) offers enhanced corrosion resistance in harsh environments. Tin-nickel plating (Amphenol ICC Delta D series) combines benefits of both finishes. Shell finish selection should align with environmental exposure and application longevity requirements.

Q: What is the difference between flange features listed as "Mating Side," "Housing/Shell," and "Board Side"?

A: Flange feature designation indicates the location of the mounting flange relative to the connector body. "Mating Side" places the flange at the connector front for panel-mount applications. "Housing/Shell" positions the flange on the connector body for board-edge mounting. "Board Side" places the flange on the rear for board-mounted applications. The TE Connectivity 5745441-4 specifies "Mating Side, Standard Screws." Flange configuration must match the intended mounting method in the application.

Q: Can connectors with different contact materials be substituted?

A: The TE Connectivity 5745441-4 uses phosphor bronze contacts. Substitute parts employ phosphor bronze, copper alloy, or brass contacts. All three materials are acceptable for D-Sub 37-position receptacles in standard signal applications. Contact material selection affects mechanical durability and electrical conductivity. Phosphor bronze and copper alloy provide superior performance characteristics compared to brass. Material substitution is acceptable provided the application does not impose specialized contact resistance or durability requirements.

Q: What does "Board Lock" feature indicate?

A: Board Lock is a mechanical feature that secures the connector to the PCB through positive locking mechanisms, preventing accidental disconnection during handling or vibration. The TE Connectivity 5745441-4 does not specify Board Lock. Several substitutes (NorComp 183-037-213R541, Amphenol ICC Delta D and SD series) include Board Lock as an optional feature. This feature is beneficial in applications subject to mechanical shock or vibration but is not required for standard stationary installations.

Q: Are there temperature range limitations for substitute selection?

A: The TE Connectivity 5745441-4 operates from -55°C to 105°C. Most substitutes extend the upper limit to 125°C, providing enhanced thermal margin. The Mercury 626-037-262-012 is limited to 85°C maximum, restricting its use to lower-temperature environments. Application operating temperature must not exceed the connector's rated maximum. Substitutes with extended temperature ranges provide design flexibility for future thermal requirement changes.
