• Number of positions (9)
• Number of rows (2)
• Shell size and connector layout (1 / DE, E)
• Mounting type (Through Hole)
• Termination method (Solder)
• Current rating (6A)
• Voltage rating (125V)
• Operating temperature range (-55°C to 105°C)
• Contact material (Brass)
• Contact finish (Gold)
• Dielectric material (Polyester)
• Material flammability rating (UL94 V-0)
• Series compatibility (AMPLIMITE HD-20)

The substitute part 5745051-2 meets all electrical and mechanical parameters required for direct substitution with the primary part 745051-2. Both parts share identical functional specifications, connector geometry, and performance ratings.

Parameter Comparison

Engineering Selection Recommendations

The 5745051-2 is a direct functional equivalent to the 745051-2 across all electrical and mechanical specifications. Both connectors are active products from TE Connectivity AMP Connectors and maintain identical performance characteristics within the AMPLIMITE HD-20 series.

A key distinction exists in regulatory compliance status. The 745051-2 is RoHS non-compliant, while the 5745051-2 is ROHS3 compliant. For applications subject to RoHS3 requirements or environmental regulations mandating lead-free and restricted substance compliance, the 5745051-2 is the appropriate selection. For applications without such regulatory constraints, either part satisfies the functional requirements.

Both parts are classified as REACH Affected and carry the same ECCN and HTSUS codes, indicating equivalent trade and regulatory treatment. The identical Moisture Sensitivity Level (MSL 1 - Unlimited) ensures equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5745051-2 be used as a direct replacement for the 745051-2 in existing designs?

A: Yes. The 5745051-2 is electrically and mechanically equivalent to the 745051-2. Both connectors share identical pin configurations, current and voltage ratings, operating temperature ranges, and physical dimensions. Direct substitution is supported from a functional standpoint.

Q: What is the primary difference between these two parts?
