Engineering Selection Recommendations

Direct Equivalent (Highest Compatibility):

The 5745782-2 from TE Connectivity AMP Connectors is the primary direct equivalent to the 745271-2. Both parts share identical electrical specifications (6A current rating, 125V voltage rating, -55°C to 105°C operating range), mechanical configuration (15-position, 2-row, right-angle through-hole), and backset spacing (0.318"). The 5745782-2 is currently in active product status with RoHS compliance, addressing the obsolescence and compliance limitations of the original part. The primary difference is the addition of a ground strap feature and improved shell material specification (steel, tin plated).

Enhanced Performance Alternatives:

Parts L77DA15SAZ4, L77DA15SCVF2, L77DAH15S1BON, and L77DFA15S1AON from Amphenol ICC (Commercial Products) provide enhanced electrical performance with 7.5A current ratings and extended operating temperature range (-55°C to 125°C). These parts maintain RoHS compliance and UL94 V-0 flammability rating. Selection among these alternatives depends on specific mounting requirements:

L77DA15SAZ4: Through-hole right-angle mounting with unthreaded housing, includes mounting brackets
L77DA15SCVF2: Free-hanging in-line configuration with solder cup termination and female screwlock mating feature
L77DAH15S1BON: Through-hole right-angle mounting with board-side 4-40 screw feature
L77DFA15S1AON: Panel mount through-hole right-angle configuration with unthreaded housing

High-Voltage Alternative:

The DAPV15S565GTLF from Amphenol ICC (FCI) is suitable for applications requiring elevated voltage performance (1000V rating) with 7.5A per contact current capacity. This part includes female screwlock mating feature and board lock capability, with extended operating temperature range to 125°C.

Current-Limited Alternative:

The DA15S565CTLF from Amphenol ICC (FCI) provides 5A current rating, which is below the original 6A specification. This part is suitable only for applications with reduced current requirements and should be evaluated for specific load conditions.

Frequently Asked Questions (FAQ)

Q: Can the 5745782-2 be used as a direct replacement for the 745271-2?

A: Yes. The 5745782-2 maintains identical electrical specifications (6A, 125V), mechanical configuration (15-position, 2-row, right-angle through-hole), and backset spacing. The primary advantages are active product status and RoHS compliance. The addition of a ground strap and improved shell material specification do not affect functional compatibility.

Q: What is the difference between the Amphenol ICC alternatives and the TE Connectivity options?

A: The Amphenol ICC alternatives (L77DA15SAZ4, L77DA15SCVF2, L77DAH15S1BON, L77DFA15S1AON) provide enhanced electrical performance with 7.5A current ratings and extended operating temperature range to 125°C, compared to the original 6A and 105°C maximum. These parts offer different mounting configurations to accommodate various application requirements. The TE Connectivity 5745782-2 maintains the original electrical specifications while providing active status and compliance improvements.

Q: Are there mounting compatibility considerations when selecting a substitute?

A: Yes. The original 745271-2 and 5745782-2 feature through-hole right-angle mounting with unthreaded housing. The Amphenol ICC alternatives offer different mounting options: L77DA15SAZ4 includes mounting brackets, L77DA15SCVF2 uses free-hanging in-line configuration with solder cup termination, L77DAH15S1BON includes board-side screw features, and L77DFA15S1AON provides panel mount capability. Verify that the selected substitute's mounting type is compatible with the target application's PCB layout and mechanical requirements.

Q: What is the significance of backset spacing differences?

A: Backset spacing defines the distance from the connector's mating face to the solder connection point. The original 745271-2 specifies 0.318" (8.08mm). Alternatives with identical spacing (5745782-2 at 0.318", L77DA15SAZ4 and L77DA15SCVF2 at 0.319") are directly compatible with existing PCB designs. Parts with larger spacing (0.406" to 0.409") require PCB layout verification to ensure adequate clearance and proper component positioning.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and hazardous substance restrictions, not electrical performance. All substitute parts listed are RoHS compliant and maintain or exceed the electrical specifications of the original 745271-2. RoHS compliance is a regulatory requirement for many applications and markets.

Q: Can the DA15S565CTLF be used if the application only requires 5A current?

A: Yes, if the application's actual current requirement is 5A or less. The DA15S565CTLF is rated for 5A, which is below the original 6A specification. Verify that the application's maximum current draw does not exceed 5A before selecting this part. All other electrical and mechanical specifications remain compatible.

Q: What is the difference between solder and solder cup termination?

A: Solder termination involves direct soldering of wire leads to contact pins on the connector body. Solder cup termination features recessed cup-shaped contact ends designed to accept and retain wire leads during soldering, providing improved mechanical support and solder joint reliability. The L77DA15SCVF2 uses solder cup termination, while other alternatives use standard solder termination. Selection depends on assembly process requirements and mechanical robustness needs.

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

A: No. The original 745271-2 packaging is not specified in the provided data. Substitute parts are available in different packaging options: 5745782-2 in tray, DA15S565CTLF in bulk, DAPV15S565GTLF in tray, and Amphenol ICC Commercial Products alternatives in tray. Verify packaging requirements for procurement and handling procedures.

Q: What is the GXT™ contact finish specification?

A: GXT™ is a proprietary gold plating specification used by Amphenol ICC (FCI) that provides enhanced durability and corrosion resistance compared to standard gold plating. Parts DAPV15S565GTLF and DA15S565CTLF feature this specification. Standard gold plating on other alternatives provides equivalent electrical performance for most applications.
