Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 747714-2 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 5747714-2 qualifies as a direct equivalent based on the following matching criteria:

Critical Matching Parameters:

• Connector style, type, and configuration (D-Sub receptacle, female sockets, 37 positions, 2 rows)
• Shell size and connector layout (Size 4, DC/C configuration)
• Mounting methodology (through-hole, press-fit termination)
• Material specifications (steel shell with tin plating, copper alloy contacts with gold finish)
• Flange design and fastening (housing/shell with 4-40 mounting)
• Environmental performance (operating temperature -55°C to 105°C, UL94 V-0 flammability rating)
• Dielectric composition (thermoplastic)
• Moisture sensitivity classification (MSL 1)

Both parts belong to the AMPLIMITE HD-20 series and maintain identical mechanical and electrical interfaces, ensuring direct interchangeability in circuit board applications and connector assemblies.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 747714-2 and 5747714-2 are functionally equivalent D-Sub receptacle connectors suitable for direct substitution in applications requiring 37-position female socket configurations with press-fit termination.

Selection Criteria Based on Compliance and Product Status:

The 5747714-2 substitute part offers RoHS compliance certification, whereas the main part 747714-2 carries a "Not applicable" RoHS status. For applications subject to RoHS Directive requirements or end-use markets requiring RoHS-compliant component documentation, the 5747714-2 is the appropriate selection.

Both parts maintain identical electrical and mechanical specifications, including operating temperature range (-55°C to 105°C), UL94 V-0 flammability rating, and REACH compliance status. Both are classified as REACH Affected and carry the same ECCN (EAR99) and HTSUS (8536.69.4040) designations.

The 5747714-2 demonstrates higher current inventory availability (1365 units versus 958 units), providing supply chain advantages for high-volume procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5747714-2 be used as a direct replacement for the 747714-2 in existing circuit board designs?

A: Yes. Both connectors are mechanically and electrically identical across all specified parameters. The 5747714-2 maintains the same 37-position configuration, shell size (4, DC/C), press-fit termination, and mounting interface. No design modifications are required for substitution.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. The 5747714-2 is RoHS Compliant, while the 747714-2 carries a "Not applicable" designation. All other electrical, mechanical, and environmental specifications are identical. The 5747714-2 also has higher inventory availability.

Q: Are both connectors suitable for the same operating temperature range?

A: Yes. Both the 747714-2 and 5747714-2 operate across the identical temperature range of -55°C to 105°C and maintain the same UL94 V-0 flammability rating.

Q: What is the significance of the press-fit termination method?

A: Press-fit termination indicates that both connectors use a mechanical insertion process for wire attachment rather than soldering. This method is suitable for through-hole mounting applications and provides consistent contact pressure without thermal stress to components.

Q: Do these connectors require any special handling or storage considerations?

A: Both connectors are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control measures are required during storage or handling. Standard industrial storage conditions are appropriate.

Q: Can these 37-position D-Sub receptacles be used with standard D-Sub plugs?

A: Compatibility depends on the plug configuration. These receptacles are designed for 37-position D-Sub plugs with matching shell size (Size 4, DC/C layout). Verify plug specifications match the receptacle shell size and pin configuration before assembly.

Q: What is the significance of the gold contact finish?

A: Gold plating on copper alloy contacts provides enhanced corrosion resistance and improved electrical conductivity compared to unplated contacts. This finish supports reliable signal transmission in industrial environments and extends connector service life.
