A: TE Connectivity parts 1-5747871-3 and 1-747871-4 maintain the AMPLIMITE HD-20 series designation and identical specifications to the original part. HARTING alternatives provide functional equivalence with variations in flange feature design, dielectric material composition, contact form (stamped versus machined), and voltage rating specifications. HARTING parts 09641227210, 09641227230, and 09641227240 feature unthreaded housing/shell flanges and 100V ratings. HARTING parts 09651216703 through 09651616733 feature mating side female screwlock (4-40) flanges matching the original design, with voltage ratings not specified in the provided data.
Q: Are HARTING D-Sub plugs compatible with TE Connectivity receptacles designed for the 1-747871-3?
A: Compatibility is determined by shell size, connector layout, and flange feature configuration. All substitute parts maintain shell size 1 (DE, E) and 9-position, 2-row configuration, ensuring mechanical mating with standard D-Sub receptacles. HARTING parts 09651216703, 09651217703, 09651296703, 09651616713, and 09651616733 feature identical mating side female screwlock (4-40) flange configuration as the original part. HARTING parts 09641227210, 09641227230, and 09641227240 feature unthreaded housing/shell flanges, which differ from the original screwlock design and may not be compatible with receptacles designed for screwlock engagement.
Q: What is the significance of RoHS3 compliance for D-Sub connector selection?
A: RoHS3 compliance indicates conformance to Restriction of Hazardous Substances regulations, restricting the use of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers. The original 1-747871-3 is non-compliant. Active alternatives 1-5747871-3 and all HARTING parts are RoHS3 compliant, meeting regulatory requirements for new product designs and markets with RoHS mandates. Non-compliant parts (1-747871-4) remain available for legacy system maintenance where regulatory exemptions apply.
Q: How do current ratings affect D-Sub connector substitution?
A: The original 1-747871-3 is rated for 6A continuous current. All substitute parts meet or exceed this requirement: TE Connectivity alternatives maintain 6A rating, while HARTING parts provide 6.5A or 7.5A ratings. Higher current ratings indicate enhanced current-carrying capacity and do not restrict substitution in applications requiring 6A or less. Applications requiring current ratings above 7.5A require alternative connector families.
Q: What packaging formats are available for D-Sub 9-position plug substitutes?
A: TE Connectivity 1-5747871-3 is supplied in tube packaging, suitable for automated pick-and-place assembly. TE Connectivity 1-747871-4 is supplied in bulk packaging for manual assembly and repair operations. HARTING parts are supplied in bulk or tray packaging formats. Packaging selection affects procurement logistics, inventory management, and assembly process compatibility. Tube packaging is optimized for high-volume automated manufacturing, while bulk and tray formats support lower-volume and manual assembly operations.
Q: Are there voltage rating limitations when substituting with HARTING D-Sub plugs?
A: The original 1-747871-3 is rated for 125V operation. TE Connectivity alternatives maintain this 125V rating. HARTING parts 09641227210, 09641227230, and 09641227240 are rated for 100V, which is below the original specification. Applications requiring 125V operation should not use these three HARTING parts. HARTING parts 09651216703, 09651217703, 09651296703, 09651616713, and 09651616733 do not specify voltage ratings in the provided data; voltage compatibility must be confirmed through additional technical documentation or manufacturer consultation.
Q: What is the operating temperature range difference between the original part and HARTING substitutes?
A: The original 1-747871-3 operates from -55°C to 105°C. TE Connectivity alternatives maintain this range. HARTING parts 09641227210, 09641227230, and 09641227240 operate from -20°C to 125°C, providing extended upper temperature capability but reduced lower temperature range. HARTING parts 09651216703, 09651217703, 09651296703, 09651616713, and 09651616733 operate from -55°C to 125°C, extending the upper limit while maintaining the lower limit. Applications requiring operation below -20°C should use parts maintaining the -55°C minimum specification.
Q: How do contact finish specifications affect D-Sub connector performance?
A: The original 1-747871-3 features gold-flashed contact finish on brass contacts. TE Connectivity 1-5747871-3 maintains identical gold-flashed finish. HARTING parts vary in contact finish specification: parts 09641227210, 09641227230, and 09641227240 do not specify contact finish; part 09651296703 specifies gold finish; remaining HARTING parts do not specify contact finish in the provided data. Contact finish affects corrosion resistance, contact resistance stability, and long-term reliability in corrosive environments. Gold-plated or gold-flashed finishes provide superior corrosion resistance compared to unspecified finishes.
