Engineering Selection Recommendations
Direct Equivalent (Highest Compatibility):
The TE Connectivity 5747834-6 is the direct equivalent to the 747834-6. Both parts share identical electrical specifications, mechanical configuration, and mounting characteristics. The primary distinction is RoHS compliance status: 5747834-6 is RoHS Compliant, while 747834-6 is RoHS non-compliant. Both maintain the same 6A current rating, 125V voltage rating, and tin-plated steel shell finish. Selection of 5747834-6 is appropriate when RoHS compliance is required or when original inventory is depleted.
Compatible Alternatives (NorComp 183 Series):
The NorComp 183-025-113R161, 183-025-113R171, 183-025-113R181, 183-025-113R531, and 183-025-113R561 connectors are functionally compatible substitutes. All five NorComp variants maintain the same 25-position, 2-row D-Sub configuration with right-angle through-hole solder termination and identical operating temperature range. Key differences include:
- Current rating reduced to 5A (acceptable for applications not requiring the full 6A capacity)
- Shell finish changed to nickel plating (Steel, Nickel Plated vs. Steel, Tin Plated)
- Contact material changed to brass (vs. copper alloy in original)
- All NorComp variants are ROHS3 Compliant and REACH Unaffected
- Flange feature configurations vary: 183-025-113R161 and 183-025-113R531 feature Housing/Shell flanges, while 183-025-113R171 features Housing/Shell (4-40), and 183-025-113R181 and 183-025-113R561 feature Mating Side Female Screwlock (4-40)
Selection among NorComp variants depends on specific flange requirements and mounting configuration needs. The 183-025-113R181 and 183-025-113R561 are most directly equivalent to the original 747834-6 due to matching mating-side female screwlock flange configuration.
Compliance Considerations:
Applications requiring RoHS compliance should utilize 5747834-6 (TE Connectivity) or any NorComp 183 series variant. Applications requiring REACH compliance should utilize NorComp variants, which are REACH Unaffected. The original 747834-6 carries undefined REACH status and is RoHS non-compliant.
Frequently Asked Questions (FAQ)
Q: Can the NorComp 183-025-113R181 directly replace the TE Connectivity 747834-6?
A: The NorComp 183-025-113R181 is mechanically and electrically compatible with the 747834-6 for applications operating at 5A or below. Both connectors feature identical 25-position, 2-row D-Sub configuration, right-angle through-hole solder termination, mating-side female screwlock flange, and -55°C to 105°C operating temperature range. The primary differences are shell finish (nickel vs. tin plating), contact material (brass vs. copper alloy), and current rating (5A vs. 6A). Direct substitution is valid when the application current requirement does not exceed 5A.
Q: What is the difference between the TE Connectivity 747834-6 and 5747834-6?
A: The 747834-6 and 5747834-6 are functionally identical connectors with the same electrical specifications, mechanical configuration, and mounting characteristics. The 5747834-6 is RoHS Compliant, while the 747834-6 is RoHS non-compliant. Both maintain 6A current rating, 125V voltage rating, tin-plated steel shell finish, and identical connector geometry. Selection between these two TE Connectivity variants depends solely on RoHS compliance requirements.
Q: Why do NorComp 183 series connectors have a lower current rating (5A vs. 6A)?
A: The current rating difference reflects design specifications established by each manufacturer. The NorComp 183 series is rated for 5A continuous current, while the TE Connectivity AMPLIMITE HD-20 series is rated for 6A. Both ratings are valid for their respective product lines. Applications requiring the full 6A capacity must use TE Connectivity parts. Applications operating at 5A or below can utilize either manufacturer's products.
Q: Are there packaging differences between the substitute parts?
A: Yes. The TE Connectivity 747834-6 and 5747834-6 are supplied in Tube packaging, while all NorComp 183 series variants (183-025-113R161, 183-025-113R171, 183-025-113R181, 183-025-113R531, 183-025-113R561) are supplied in Tray packaging. Packaging format does not affect connector performance or compatibility; it only impacts storage, handling, and inventory management.
Q: Which substitute part should I select if my application requires a mating-side female screwlock flange?
A: For mating-side female screwlock (4-40) flange configuration, select either the TE Connectivity 5747834-6 or the NorComp 183-025-113R181 or 183-025-113R561. These three parts feature identical flange geometry to the original 747834-6. The NorComp 183-025-113R161 and 183-025-113R531 feature Housing/Shell flanges and are not suitable if mating-side screwlock mounting is required.
Q: What is the significance of the shell material finish difference (tin vs. nickel plating)?
A: Shell material finish affects corrosion resistance and environmental performance. Tin plating (747834-6, 5747834-6) provides one corrosion protection profile, while nickel plating (NorComp 183 series) provides an alternative profile. Both finishes support the UL94 V-0 flammability rating and operate across the -55°C to 105°C temperature range. Selection between tin and nickel plating depends on specific environmental exposure requirements and application standards.
Q: Are all substitute parts currently in active production?
A: Yes. The TE Connectivity 747834-6, 5747834-6, and all five NorComp 183 series variants (183-025-113R161, 183-025-113R171, 183-025-113R181, 183-025-113R531, 183-025-113R561) are all listed as Active product status. All parts maintain current inventory availability.
Q: Can I use a NorComp 183-025-113R161 if my design requires a Housing/Shell (Unthreaded) flange?
A: Yes. The NorComp 183-025-113R161 features a Housing/Shell (Unthreaded) flange configuration, which differs from the original 747834-6 mating-side female screwlock design. This variant is suitable for applications where an unthreaded housing flange is acceptable. If your design specifically requires mating-side screwlock mounting, select 183-025-113R181 or 183-025-113R561 instead.
