The substitute part TE Connectivity 5206973-2 (base number 5206973) and 5745116-2 (base number 5745116) both satisfy these critical parameters. The 5745116-2 represents an active product variant within the AMPLIMITE HDP-20 series, offering improved availability compared to the obsolete HD-20 series original.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 5745116-2

The 5745116-2 is the qualified substitute for the obsolete 5206973-2. Both connectors maintain identical electrical and core mechanical specifications across all critical parameters: 50 position receptacle configuration, 3-row layout, shell size 5 (DD, D), 6A current rating, 125V voltage rating, and -55°C to 105°C operating temperature range. Both parts are ROHS3 compliant with MSL 1 rating.

Differences and Considerations:

The 5745116-2 introduces the following variations from the original 5206973-2:

1. Product Status: The 5745116-2 is active, ensuring ongoing availability and supply chain support compared to the obsolete status of the original part.

2. Series Designation: The substitute belongs to the AMPLIMITE HDP-20 series versus the original AMPLIMITE HD-20 series, representing an evolution within the TE Connectivity D-Sub connector portfolio.

3. Dielectric Material: The 5745116-2 uses polyamide (PA) nylon with glass filling, providing enhanced material flammability rating (UL94 V-0) compared to the thermoplastic material of the original.

4. Shell Construction: The 5745116-2 features steel shell material with tin plating and includes mounting brackets with standard 4-40 screws, whereas the original has an unthreaded housing/shell design.

5. Backset Spacing: The 5745116-2 specifies 0.545" (13.84mm) backset spacing compared to 0.590" (14.99mm) for the original. This dimensional difference requires verification against printed circuit board layout and mechanical mounting requirements.

6. Contact Material: The 5745116-2 specifies phosphor bronze contact material, providing additional technical specification clarity.

Compliance Status:

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The 5745116-2 provides documented UL94 V-0 flammability rating, enhancing material safety documentation.

Selection Criteria:

Selection of the 5745116-2 as a substitute is appropriate when:

• Active product availability is required
• Enhanced material specifications (UL94 V-0 flammability) are acceptable or beneficial
• Mounting bracket integration with 4-40 screw fastening is compatible with system design
• Backset spacing of 0.545" (13.84mm) accommodates existing PCB layout and mechanical constraints

Frequently Asked Questions (FAQ)

Q: Can the 5745116-2 directly replace the 5206973-2 in existing designs?

A: The 5745116-2 maintains electrical compatibility across all critical parameters: 50 positions, 3 rows, shell size 5 (DD, D), 6A current, 125V voltage, and -55°C to 105°C operating range. However, the backset spacing differs (0.545" versus 0.590"), and the flange design changes from unthreaded housing to screw-mounted brackets. Verification against specific PCB layout and mechanical mounting requirements is necessary before implementation.

Q: What is the significance of the backset spacing difference?

A: Backset spacing defines the distance from the connector mounting plane to the rear of the connector body. The 5745116-2 backset of 0.545" (13.84mm) differs from the original 0.590" (14.99mm). This affects the overall depth profile and must be evaluated against available PCB space and system enclosure constraints.

Q: Are both parts RoHS compliant?

A: Yes, both the 5206973-2 and 5745116-2 are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.

Q: What is the difference between the AMPLIMITE HD-20 and HDP-20 series?

A: The 5206973-2 belongs to the AMPLIMITE HD-20 series (obsolete), while the 5745116-2 belongs to the AMPLIMITE HDP-20 series (active). The HDP-20 represents an updated product line with enhanced specifications including improved flammability rating (UL94 V-0) and integrated mounting bracket features.

Q: Does the dielectric material change affect electrical performance?

A: Both dielectric materials (thermoplastic in the original and polyamide nylon glass-filled in the substitute) support the identical electrical ratings of 6A current and 125V voltage across the -55°C to 105°C temperature range. The polyamide material in the 5745116-2 provides enhanced material flammability characteristics.

Q: What is the contact material composition?

A: The 5745116-2 specifies phosphor bronze contact material with gold finish. The original 5206973-2 contact material composition is not specified in the provided documentation.

Q: Are there packaging differences between the two parts?

A: The 5206973-2 packaging is not specified in the provided data. The 5745116-2 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What inventory status should be considered?

A: The 5206973-2 shows 675 pieces in stock as new original inventory. The 5745116-2 shows 906 pieces in stock as new original inventory. As an active product, the 5745116-2 offers superior long-term availability compared to the obsolete 5206973-2.

Q: Are both parts suitable for the same voltage and current applications?

A: Yes, both parts are rated for 6A current and 125V voltage, making them electrically equivalent for applications within these specifications.

Q: What mounting configuration differences exist?

A: Both parts feature through-hole, right-angle mounting. The primary difference is the flange design: the 5206973-2 has an unthreaded housing/shell, while the 5745116-2 includes mating side standard screws (4-40) with mounting brackets.
