Frequently Asked Questions (FAQ)
Q: Can HARTING 09641127235 directly replace DEML09S300? A: HARTING 09641127235 matches the core functional parameters: 9-position D-Sub receptacle, female sockets, DE/E shell size, through-hole solder termination, and board-side flange. However, it is rated for 100V versus 300V, and operates at -20°C to 125°C versus -55°C to 125°C. Substitution is valid only if application voltage and temperature requirements do not exceed these limits. HARTING 09641127235 is ROHS3 compliant, whereas DEML09S300 is not.
Q: What is the difference between HARTING mating-side screwlock variants (09661116503, 09661117503, 09661556513)? A: All three are 9-position D-Sub receptacles with mating-side female screwlock flanges (4-40). 09661116503 and 09661117503 have unspecified contact finish; 09661556513 features gold contact finish. 09661556513 includes a board lock feature. All three support -55°C to 125°C and are ROHS3 compliant. Selection depends on contact finish and board lock requirements.
Q: Are TE Connectivity AMPLIMITE HD-20 series parts suitable for -55°C to 125°C applications? A: TE Connectivity AMPLIMITE HD-20 series (1-5747150-3, 1-5747150-4, 1-5747150-6, 1-747150-4) are rated for -55°C to 105°C, not 125°C. They are not suitable for applications requiring operation above 105°C. HARTING variants and DEML09S300 support the full -55°C to 125°C range.
Q: What packaging options are available? A: DEML09S300 is supplied in trays (966 units in stock). HARTING parts are supplied in bulk packaging (1024 to 1873 units in stock). TE Connectivity 1-338313-2 is supplied in trays (2800 units). TE Connectivity 1-5747150-3, 1-5747150-4, and 1-5747150-6 are supplied in tubes (1757 to 7581 units). TE Connectivity 1-747150-4 is supplied in bulk (1899 units).
Q: Which substitute parts are RoHS compliant? A: HARTING 09641127230, 09641127235, 09661116503, 09661117503, and 09661556513 are ROHS3 compliant. TE Connectivity 1-338313-2, 1-5747150-3, 1-5747150-4, and 1-5747150-6 are RoHS compliant. DEML09S300 and TE Connectivity 1-747150-4 are RoHS non-compliant.
Q: What is the current rating difference between DEML09S300 and substitute parts? A: DEML09S300 is rated for 7.5A. HARTING 09641127230 and 09641127235 are rated for 7.5A. HARTING 09661116503, 09661117503, and 09661556513 are rated for 6.5A. All TE Connectivity variants are rated for 6.0A. Current rating selection must match or exceed application requirements.
Q: Can I use a 100V-rated part in a 300V circuit? A: No. Voltage rating is a maximum specification. Using a part rated for 100V in a 300V circuit creates an electrical safety hazard and violates design specifications. Select parts with voltage ratings equal to or greater than circuit voltage requirements.
