Key Parameters

Substitute Part Grouping Explanation

Substitution of the 745215-2 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (D-Sub Plug, Male Pins)
• Number of positions (37)
• Number of rows (2)
• Shell size and layout (4, DC, C)
• Mounting type (Free Hanging, In-Line)
• Flange feature (Housing/Shell, Unthreaded)

Electrical Compatibility:

• Termination method (IDC, Discrete Wire)
• Wire gauge range (22-26 AWG)
• Voltage rating (250V)
• Operating temperature range (-55°C ~ 105°C)
• Contact material (Phosphor Bronze)
• Contact finish (Gold)

Material and Safety Compliance:

• Dielectric material (Thermoplastic)
• Material flammability rating (UL94 V-0)
• Series designation (AMPLIMITE HDE-20)

The substitute part 745215-7 maintains full equivalence across all mechanical, electrical, and material parameters. Differences in product status, packaging format, contact finish thickness specification, and RoHS compliance do not affect functional interchangeability in applications requiring the 745215-2.

Parameter Comparison

Engineering Selection Recommendations

The 745215-7 is a direct functional equivalent to the 745215-2 across all critical mechanical and electrical parameters. Selection between these parts should be based on the following factors:

Product Status Consideration: The 745215-2 is classified as obsolete, while the 745215-7 maintains active product status. For new designs, system upgrades, or long-term component availability, the 745215-7 is the appropriate selection.

Regulatory Compliance: The 745215-7 is RoHS compliant, whereas the 745215-2 is RoHS non-compliant. Applications subject to RoHS regulations or requiring compliance documentation must use the 745215-7.

Legacy System Support: For existing installations or systems currently utilizing the 745215-2, the 745215-7 provides direct substitution without modification to connector interfaces, mating equipment, or wiring harnesses.

Contact Finish Specification: The 745215-2 specifies a contact finish thickness of 30.0µin (0.76µm), while the 745215-7 specifies flash gold plating. Both finishes provide equivalent electrical performance and corrosion resistance for the specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the 745215-7 be used as a direct replacement for the 745215-2 in existing applications?

A: Yes. The 745215-7 is mechanically and electrically equivalent to the 745215-2. Both connectors share identical pin configurations, shell dimensions, mounting characteristics, and electrical ratings. No modifications to mating connectors, cable assemblies, or installation procedures are required.

Q: What is the difference between the contact finish specifications of these two parts?

A: The 745215-2 specifies a gold contact finish with a thickness of 30.0µin (0.76µm). The 745215-7 specifies flash gold plating. Both finishes provide adequate corrosion resistance and electrical conductivity for the connector's rated voltage and current applications. Flash plating is a thinner, more economical finish that maintains performance within the specified operating parameters.

Q: Why is the 745215-2 listed as obsolete?

A: The 745215-2 has been superseded by the 745215-7, which offers improved regulatory compliance (RoHS compliant status) and active manufacturing support. Obsolete designation indicates that the manufacturer no longer produces this part as a standard offering.

Q: Are there any compatibility issues with the packaging difference between these parts?

A: No. The 745215-2 packaging format is not specified in the available documentation. The 745215-7 is supplied in tray packaging. Packaging format does not affect connector performance, electrical characteristics, or mechanical compatibility. Packaging selection is a logistical consideration for inventory management and handling.

Q: What wire gauges are compatible with both connectors?

A: Both the 745215-2 and 745215-7 accept wire gauges from 22 to 26 AWG. This range applies to both IDC and discrete wire termination methods. Wire gauge selection must match the specific application requirements and the termination tooling used.

Q: Can these connectors be used in applications requiring RoHS compliance?

A: The 745215-7 is RoHS compliant and is suitable for applications with RoHS requirements. The 745215-2 is RoHS non-compliant and cannot be used in applications where RoHS compliance is mandated. For new designs or systems requiring regulatory compliance, the 745215-7 must be specified.

Q: What is the operating temperature range for these connectors?

A: Both connectors operate across a temperature range of -55°C to 105°C. This range covers typical industrial, commercial, and military applications. Connector performance remains within specification across this entire range.

Q: Are both connectors rated for the same voltage?

A: Yes. Both the 745215-2 and 745215-7 are rated for 250V. This voltage rating applies to the signal contacts and the dielectric material. Application voltage requirements must not exceed this specification.
