Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Same Electrical and Mechanical Specifications):

The part numbers 747844-5 is a direct equivalent to 7-747844-0. Both are manufactured by TE Connectivity AMP Connectors within the AMPLIMITE HD-20 series and share identical electrical ratings (6A, 125V), operating temperature range (-55°C to 105°C), and mechanical specifications. The primary difference is RoHS and REACH compliance status, which does not affect functional compatibility. Selection between these two parts depends on regulatory requirements for the end application.

Functional Equivalents with Compliance Advantages:

The part number 5788797-2 is functionally equivalent to 7-747844-0 with the advantage of RoHS compliance and REACH unaffected status. This part is also manufactured by TE Connectivity AMP Connectors within the AMPLIMITE HD-20 series and maintains identical electrical ratings and mechanical specifications. The dielectric material differs (Polyamide/Nylon versus Thermoplastic), but both materials meet UL94 V-0 flammability requirements. This part is suitable for applications requiring RoHS compliance.

Cross-Manufacturer Equivalents with Parameter Variations:

The part numbers L77SDE09S1ACH4F48 and L77SDE09SA4CH4F are manufactured by Amphenol ICC (Commercial Products) within the SD series. These parts maintain mechanical compatibility and core electrical characteristics but feature reduced current rating (3A versus 6A) and elevated voltage rating (250V versus 125V). The operating temperature range extends to 125°C (versus 105°C). The dielectric material is Thermoplastic Glass Filled, and both parts are RoHS compliant. These parts are suitable for applications where the lower current rating is acceptable and higher voltage or extended temperature operation is beneficial.

Selection Basis:

• For RoHS-compliant applications: Select 5788797-2 or Amphenol ICC alternatives (L77SDE09S1ACH4F48, L77SDE09SA4CH4F)
• For non-compliant applications with identical specifications: Select 747844-5
• For applications requiring extended voltage or temperature ratings: Select Amphenol ICC alternatives
• For applications with current requirements up to 6A: Select 7-747844-0, 747844-5, or 5788797-2
• For applications with current requirements up to 3A: All parts are suitable

Frequently Asked Questions (FAQ)

Q: Can 5788797-2 be used as a direct replacement for 7-747844-0?

A: Yes. The 5788797-2 is a direct functional equivalent with identical connector type, position count, mounting configuration, electrical ratings (6A, 125V), and operating temperature range (-55°C to 105°C). The primary advantage is RoHS compliance and REACH unaffected status. The dielectric material differs (Polyamide/Nylon versus Thermoplastic), but both meet UL94 V-0 flammability requirements and are functionally interchangeable.

Q: What is the difference between 747844-5 and 7-747844-0?

A: These parts are electrically and mechanically identical. Both are TE Connectivity AMP Connectors AMPLIMITE HD-20 series 9-position D-Sub receptacles with 6A current rating, 125V voltage rating, and -55°C to 105°C operating temperature. The difference is in regulatory compliance: 7-747844-0 is RoHS non-compliant and REACH affected, while 747844-5 maintains the same compliance status. Selection depends on application regulatory requirements.

Q: Can Amphenol ICC L77SDE09S1ACH4F48 or L77SDE09SA4CH4F replace the TE Connectivity 7-747844-0?

A: These Amphenol ICC parts are mechanically compatible and maintain the same connector type, position count, mounting configuration, and shell specifications. However, they feature reduced current rating (3A versus 6A) and elevated voltage rating (250V versus 125V). They are suitable for applications where the 3A current rating is sufficient and the higher voltage rating is acceptable or beneficial. Extended operating temperature to 125°C is an additional advantage.

Q: Are all substitute parts available in the same packaging?

A: Yes. All listed parts are supplied in Tray packaging, consistent with the original 7-747844-0 specification.

Q: What is the significance of the dielectric material differences?

A: The main part (7-747844-0) uses Thermoplastic dielectric material. The 5788797-2 substitute uses Polyamide (PA) Nylon, and the Amphenol ICC parts use Thermoplastic Glass Filled material. All materials meet UL94 V-0 flammability requirements. The material differences do not affect functional compatibility or electrical performance within the specified operating parameters.

Q: Which substitute part has the best compliance profile?

A: The 5788797-2 (TE Connectivity) and both Amphenol ICC parts (L77SDE09S1ACH4F48 and L77SDE09SA4CH4F) are RoHS compliant. The 5788797-2 is additionally REACH unaffected. For applications requiring maximum compliance, 5788797-2 is the preferred TE Connectivity option, or either Amphenol ICC part if cross-manufacturer sourcing is acceptable.

Q: Can I use an Amphenol ICC part in an application designed for 6A current?

A: No. The Amphenol ICC parts (L77SDE09S1ACH4F48 and L77SDE09SA4CH4F) are rated for 3A maximum current. They are suitable only for applications where the current requirement does not exceed 3A. For applications requiring 6A capability, use 7-747844-0, 747844-5, or 5788797-2.

Q: What is the inventory status of each part?

A: Current inventory levels are: 7-747844-0 (738 pcs), 5788797-2 (1500 pcs), 747844-5 (1372 pcs), L77SDE09S1ACH4F48 (1216 pcs), and L77SDE09SA4CH4F (1617 pcs). All parts are listed as new original stock.
