Substitute Part Grouping Explanation

Substitution of the Greenlee Communications 45740 is based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Plug configuration
• Number of Positions/Contacts: 8P8C (RJ45, Ethernet) standard
• Cable Type: Flat oval cable with stranded wire compatibility
• Termination Method: Crimp interface
• Contact Finish: Gold plating for electrical performance
• Housing Color: Translucent clear appearance

The substitute part TM4P-88P from Hirose Electric Co Ltd satisfies all mandatory parameters. Both connectors are designed for identical electrical interfaces and mechanical cable accommodation, enabling direct functional replacement in 8P8C modular connector applications.

Parameter Comparison

Engineering Selection Recommendations

The Hirose Electric Co Ltd TM4P-88P connector is the designated substitute for the obsolete Greenlee Communications 45740. Selection of this substitute is supported by the following engineering factors:

Product Status: The TM4P-88P maintains active product status with current manufacturing and distribution, ensuring long-term availability and supply chain reliability compared to the obsolete 45740.

Regulatory Compliance: The TM4P-88P is RoHS Compliant, meeting current environmental and hazardous substance restrictions. The original 45740 carries "Not applicable" RoHS status, indicating it predates current compliance requirements.

Electrical and Mechanical Equivalence: Both connectors share identical 8P8C RJ45 Ethernet specifications, crimp termination methodology, gold contact finish, and flat oval cable accommodation. These parameters ensure functional interchangeability in modular connector applications.

Classification Alignment: Both parts maintain identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications, confirming regulatory and trade alignment.

Moisture Sensitivity: Both connectors carry MSL 1 (Unlimited) ratings, indicating equivalent environmental performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Hirose TM4P-88P directly replace the Greenlee 45740 in existing installations?

A: Yes. Both connectors are 8P8C RJ45 Ethernet plugs with crimp termination, gold contacts, and flat oval cable compatibility. The electrical interface and mechanical form factor are equivalent.

Q: What is the primary reason for substitution?

A: The Greenlee 45740 is classified as obsolete. The Hirose TM4P-88P is an active product with current manufacturing support, ensuring supply availability and long-term component sourcing.

Q: Are there differences in housing material between these connectors?

A: The Hirose TM4P-88P specifies polycarbonate (PC) housing material. The Greenlee 45740 housing material is not specified in available documentation. Both maintain translucent clear appearance and identical functional performance.

Q: Do both connectors meet current environmental compliance standards?

A: The Hirose TM4P-88P is RoHS Compliant. The Greenlee 45740 carries "Not applicable" RoHS status, reflecting its obsolete product classification. For new designs or compliance-sensitive applications, the TM4P-88P is the appropriate selection.

Q: What is the contact material difference?

A: The Hirose TM4P-88P uses phosphor bronze contacts with gold plating. The Greenlee 45740 contact material is not specified. Both maintain gold contact finish for electrical performance.

Q: Are the moisture sensitivity ratings equivalent?

A: Yes. Both connectors carry MSL 1 (Unlimited) ratings, indicating identical moisture sensitivity performance and storage requirements.

Q: What packaging is available for the substitute part?

A: The Hirose TM4P-88P is supplied in bulk packaging. The Greenlee 45740 packaging specification is not provided.
