Key Parameters

Substitute Part Grouping Explanation

Substitution of D-Sub receptacle connectors is determined by strict equivalence across the following critical parameters: connector type (receptacle, female sockets), number of positions (9), shell size and layout (1, DE/E), mounting configuration (through-hole, right-angle), termination method (solder), electrical ratings (6A, 125V), operating temperature range (-55°C to 105°C), shell material and finish (steel, tin-plated), contact material (phosphor bronze), contact finish (gold, 30.0µin), flange feature (4-40), and board lock feature.

The substitute parts identified maintain full electrical and mechanical compatibility with the main part number 6-747844-9. Variations in dielectric material composition and regulatory compliance status are noted but do not affect functional interchangeability within the specified electrical and thermal parameters.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain full functional equivalence to the main part number 6-747844-9 across all critical electrical and mechanical parameters. Selection among the substitute options should be based on regulatory compliance requirements and product status considerations.

For RoHS Compliance Applications: Parts 5788796-1 and 6-788796-7 carry ROHS3 Compliant status and REACH Unaffected designation, making them suitable for applications requiring adherence to current RoHS directives and REACH regulations.

For Legacy or Non-Regulated Applications: Part 747844-4 maintains active product status but carries RoHS non-compliant and REACH Affected designations. This part is suitable only for applications without RoHS or REACH compliance requirements.

For Vendor-Undefined Compliance Status: The main part number 6-747844-9 carries Vendor Undefined REACH status. Applications requiring explicit REACH compliance confirmation should utilize parts 5788796-1 or 6-788796-7.

Dielectric Material Consideration: Parts 5788796-1 and 6-788796-7 utilize Polyamide (PA) Nylon dielectric material, while 6-747844-9 and 747844-4 utilize Thermoplastic dielectric material. Both material compositions meet UL94 V-0 flammability requirements and operate within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts electrically interchangeable with the main part 6-747844-9?

A: Yes. All substitute parts (747844-4, 5788796-1, and 6-788796-7) maintain identical electrical specifications including 6A current rating, 125V voltage rating, and -55°C to 105°C operating temperature range. They are electrically interchangeable.

Q: Are all substitute parts mechanically interchangeable with the main part 6-747844-9?

A: Yes. All substitute parts share identical mechanical specifications including 9-position D-Sub receptacle configuration, shell size 1 (DE, E), through-hole right-angle mounting, 0.318" (8.08mm) backset spacing, and 4-40 flange feature. They are mechanically interchangeable.

Q: What is the difference between the dielectric materials used in these parts?

A: The main part 6-747844-9 and substitute 747844-4 use Thermoplastic dielectric material. Substitutes 5788796-1 and 6-788796-7 use Polyamide (PA) Nylon dielectric material. Both material types meet UL94 V-0 flammability requirements and operate across the full -55°C to 105°C temperature range. Material selection does not affect electrical or mechanical performance within specified parameters.

Q: Which substitute parts are suitable for RoHS-compliant applications?

A: Parts 5788796-1 and 6-788796-7 carry ROHS3 Compliant status. These parts are suitable for applications requiring RoHS compliance. Part 747844-4 is RoHS non-compliant and should not be used in RoHS-regulated applications.

Q: What is the difference in REACH status among the substitute parts?

A: Parts 5788796-1 and 6-788796-7 carry REACH Unaffected status, indicating they are not subject to REACH substance restrictions. Part 747844-4 carries REACH Affected status, indicating it may contain substances of concern under REACH regulations. The main part 6-747844-9 carries Vendor Undefined REACH status.

Q: Can I use part 747844-4 as a substitute for 6-747844-9?

A: Part 747844-4 is electrically and mechanically equivalent to 6-747844-9. However, 747844-4 is RoHS non-compliant and REACH Affected. Use 747844-4 only in applications without RoHS or REACH compliance requirements.

Q: Are there inventory differences among the substitute parts?

A: Yes. Current inventory levels are: 6-747844-9 (690 Pcs), 747844-4 (1277 Pcs), 5788796-1 (3384 Pcs), and 6-788796-7 (784 Pcs). Inventory availability should be verified at the time of procurement.

Q: Do all parts use the same contact material and finish?

A: Yes. All parts use Phosphor Bronze contact material with gold plating at 30.0µin (0.76µm) thickness. Contact specifications are identical across all parts.

Q: What is the Board Lock feature?

A: Board Lock is a mechanical feature present on all listed parts that provides positive retention of the connector to the printed circuit board, preventing accidental disconnection during handling or vibration.

Q: Are all parts rated for the same current and voltage?

A: Yes. All parts are rated for 6A current and 125V voltage. Electrical ratings are identical across all substitute parts.
