Engineering Selection Recommendations
TE Connectivity AMPLIMITE HD-20 Series with Mating-Side Screwlock (Recommended Primary Substitutes):
Parts 1-5747871-3, 1-5747871-4, 1-5747871-6, 1-747871-4, and 1-747871-6 maintain identical flange configuration (mating-side female screwlock 4-40) to the DEMV09P300. These parts are all active in production. Selection among these variants depends on RoHS compliance requirements and packaging preference:
- 1-5747871-3, 1-5747871-6, and 1-747871-6 are ROHS3 compliant
- 1-5747871-4 is RoHS compliant
- 1-747871-4 is RoHS non-compliant (equivalent to original part compliance status)
Tube packaging is available for 1-5747871-3, 1-5747871-4, 1-5747871-6, and 1-747871-6. Bulk packaging is available for 1-747871-4.
TE Connectivity AMPLIMITE HD-20 Series with Housing/Shell Flange (Secondary Substitutes):
Parts 2-748003-0 and 2-5748003-0 feature housing/shell flange (4-40) instead of mating-side screwlock. These are suitable only when the flange configuration change is acceptable for the application. Part 2-5748003-0 is ROHS3 compliant; part 2-748003-0 is RoHS non-compliant.
NorComp 172 Series (Panel Mount Variants):
Parts 172-009-112R001, 172-E09-113R011, and 172-E09-113R911 include panel mount capability in addition to through-hole mounting. Part 172-009-112R001 is obsolete and should not be selected for new designs. Parts 172-E09-113R011 and 172-E09-113R911 are active and ROHS3 compliant. Part 172-E09-113R911 includes both board-side and mating-side flanges with board lock feature.
Compliance and Temperature Considerations:
All substitute parts operate at -55°C ~ 105°C or -50°C ~ 100°C, which is narrower than the original DEMV09P300 specification of -55°C ~ 125°C. Applications requiring operation above 105°C cannot use these substitutes. All substitute parts maintain UL94 V-0 flammability rating and brass contact material.
Frequently Asked Questions (FAQ)
Q: Can I use a substitute part with a different flange configuration?
A: Flange configuration determines how the connector is secured to the mating connector or housing. The DEMV09P300 uses mating-side female screwlock (4-40). Substitutes with housing/shell flange (2-748003-0, 2-5748003-0) or board-side flange (172-E09-113R011, 172-E09-113R911) are mechanically incompatible with existing mating connectors designed for mating-side screwlock. Use only if the mating connector is also changed.
Q: What is the impact of lower current rating on substitute parts?
A: The DEMV09P300 is rated for 7.5A; most substitutes are rated for 6A or 5A. Lower current ratings are acceptable for signal applications where current does not approach the rated limit. For applications requiring 7.5A continuous current, verify that the substitute part's 6A or 5A rating is sufficient for the actual circuit current.
Q: Are the NorComp 172 series parts suitable for my application?
A: NorComp 172 series parts include panel mount capability and different dielectric materials (PBT or PA6T) compared to the thermoplastic dielectric in the DEMV09P300 and TE Connectivity parts. Part 172-009-112R001 is obsolete and unsuitable for new designs. Active NorComp parts (172-E09-113R011, 172-E09-113R911) are ROHS3 compliant and operate at -50°C ~ 100°C. These are suitable only if panel mount capability is required or if the narrower temperature range is acceptable.
Q: What is the difference between RoHS non-compliant, RoHS compliant, and ROHS3 compliant?
A: RoHS non-compliant parts may contain restricted substances such as lead or cadmium. RoHS compliant parts meet the original Restriction of Hazardous Substances directive. ROHS3 compliant parts meet the updated RoHS 3 directive. The DEMV09P300 is RoHS non-compliant due to yellow cadmium plating. Substitutes with ROHS3 compliance (1-5747871-3, 1-5747871-6, 1-747871-6, 2-5748003-0, 172-E09-113R011, 172-E09-113R911) are suitable for applications with RoHS compliance requirements.
Q: Does packaging format affect connector performance?
A: Packaging format (tray, tube, or bulk) does not affect electrical or mechanical performance. Packaging selection depends on inventory management, handling, and assembly process requirements. Tray packaging is suitable for automated pick-and-place assembly. Tube packaging provides compact storage. Bulk packaging is economical for high-volume applications.
Q: Can I use a substitute part with a different shell finish?
A: The DEMV09P300 has yellow cadmium plating; substitutes have tin or nickel plating. Shell finish affects corrosion resistance and environmental compatibility. Tin and nickel plating provide corrosion resistance suitable for most industrial environments. Yellow cadmium plating is no longer used in new designs due to environmental and health concerns. Tin or nickel plating is acceptable for equivalent performance in standard operating environments.
Q: What is the operating temperature limitation for substitute parts?
A: The DEMV09P300 operates at -55°C ~ 125°C. TE Connectivity substitutes operate at -55°C ~ 105°C. NorComp substitutes operate at -50°C ~ 100°C. Applications requiring operation above 105°C cannot use these substitutes. Applications requiring operation below -50°C cannot use NorComp parts. Verify that the substitute part's temperature range encompasses the application's operating environment.
