Key Parameters

Substitute Part Grouping Explanation

Substitution of the 8-1437504-5 is determined by strict equivalence across the following critical parameters:

Functional Compatibility Parameters:

• Connector type: Transistor socket for TO-3 packages
• Position count: 3 positions with oval configuration
• Mounting method: Chassis mount with solder termination
• Frame type: Closed frame construction
• Contact finish: Tin plating on both mating and post surfaces

Environmental Compatibility Parameters:

• Moisture sensitivity level: MSL 1 (Unlimited)
• Operating temperature range: Minimum -55°C to 125°C or broader

Mechanical Compatibility Parameters:

• Termination method: Solder-type posts
• Contact material: Beryllium copper or equivalent conductive material

The Keystone Electronics 4516 meets all functional, environmental, and mechanical compatibility requirements for direct substitution. Both parts share identical connector topology, position configuration, mounting approach, and contact finish specifications. The substitute part is currently in active production status, ensuring availability for ongoing applications.

Parameter Comparison

Engineering Selection Recommendations

The Keystone Electronics 4516 is the appropriate substitute for the obsolete TE Connectivity 8-1437504-5 based on the following engineering criteria:

Functional Equivalence: Both connectors provide identical TO-3 transistor socket functionality with 3-position oval configuration, chassis mount installation, and solder termination. Electrical and mechanical interface compatibility is established through matching contact finish, frame type, and position geometry.

Compliance Status: The Keystone Electronics 4516 holds active product status with ROHS3 compliance certification and REACH unaffected designation. These certifications support deployment in regulated manufacturing and supply chain environments. The original TE Connectivity part carries obsolete status with undefined compliance documentation, limiting its suitability for new applications and long-term procurement.

Availability and Supply Chain: The Keystone Electronics 4516 maintains active inventory in bulk packaging format, ensuring reliable procurement for production and service requirements. The original part, while currently in stock, faces discontinuation risk due to obsolete classification.

Environmental Performance: Both parts operate across the required temperature range and maintain MSL 1 moisture sensitivity rating, confirming suitability for standard storage and handling conditions without specialized environmental controls.

Frequently Asked Questions (FAQ)

Q: Can the Keystone Electronics 4516 directly replace the TE Connectivity 8-1437504-5 in existing assemblies?

A: Yes. Both connectors share identical TO-3 transistor socket specifications, 3-position oval configuration, chassis mount design, and solder termination. Direct mechanical and electrical substitution is supported without circuit board or assembly modifications.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active), housing material (PTFE versus PBT), contact material (beryllium copper versus brass), and compliance certifications. Functionally, both parts meet the same electrical and mechanical interface requirements for TO-3 transistor socket applications.

Q: Does the housing material difference affect performance?

A: Both PTFE and PBT housing materials are suitable for the specified operating temperature range of -55°C to 125°C and MSL 1 moisture conditions. The material difference does not impact electrical performance or mechanical compatibility in standard applications.

Q: Are there any packaging considerations when switching to the Keystone Electronics 4516?

A: The Keystone Electronics 4516 is supplied in bulk packaging, whereas the original part packaging format is not specified. Verify bulk packaging compatibility with your receiving, storage, and assembly processes.

Q: What compliance certifications should I verify for new applications?

A: The Keystone Electronics 4516 carries ROHS3 compliance and REACH unaffected status. Confirm these certifications align with your application requirements and regional regulatory obligations before final selection.

Q: Is the operating temperature range identical between both parts?

A: The TE Connectivity 8-1437504-5 specifies -55°C to 125°C operating range. The Keystone Electronics 4516 does not provide an explicit operating temperature specification in the available data. Verify temperature performance requirements with the Keystone Electronics technical documentation for your specific application environment.
