Key Parameters

Substitute Part Grouping Explanation

Substitution of the 8080-1G35 is determined by the following critical parameters that must align across equivalent parts:

Functional Parameters:

• Type: Transistor, TO-3 socket
• Number of Positions: 3 (Oval configuration)
• Mounting Type: Chassis Mount
• Termination: Solder

Electrical Parameters:

• Contact Finish: Tin or Tin-Lead (compatible finishes for TO-3 applications)
• Contact Material: Beryllium Copper or Brass (both acceptable for transistor socket applications)
• Flammability Rating: UL94 V-0 (required for safety compliance)

Environmental Parameters:

• Moisture Sensitivity Level: 1 (Unlimited)
• Operating Temperature Range: Compatible with -55°C ~ 125°C or broader range

The Keystone Electronics 4516 qualifies as a substitute based on matching all functional parameters, maintaining equivalent electrical performance through compatible contact materials and finishes, and meeting the same flammability standard.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production Continuity:

The Keystone Electronics 4516 is the designated substitute for the obsolete TE Connectivity 8080-1G35. This substitution is supported by:

1. Functional Equivalence: Both components are 3-position TO-3 transistor sockets with identical pin configurations and chassis mount termination.

2. Electrical Compatibility: The 4516 maintains equivalent electrical performance through brass contact material and tin finish, which are standard alternatives to beryllium copper and tin-lead in TO-3 socket applications. Both achieve UL94 V-0 flammability compliance.

3. Active Product Status: The Keystone Electronics 4516 is an active product with confirmed inventory availability (2200 pieces), ensuring supply chain continuity.

4. Regulatory Compliance: The 4516 achieves ROHS3 compliance and REACH unaffected status, providing advantages over the non-compliant 8080-1G35 for applications subject to modern regulatory requirements.

5. Housing Material Difference: The 4516 uses polybutylene terephthalate (PBT) instead of diallyl phthalate (DAP). Both materials meet UL94 V-0 requirements and are suitable for chassis mount transistor socket applications.

Frequently Asked Questions (FAQ)

Q: Can the Keystone Electronics 4516 directly replace the TE Connectivity 8080-1G35 in existing designs?

A: Yes. Both components are 3-position TO-3 transistor sockets with identical pin configurations, chassis mount termination, and solder attachment. The functional and electrical parameters align for direct substitution.

Q: What is the difference between tin-lead and tin contact finishes in this application?

A: Tin-lead and tin are both acceptable contact finishes for TO-3 transistor sockets. Tin is the modern standard and is used in the 4516. Both finishes provide equivalent electrical performance and solderability for this socket type.

Q: Why does the 4516 use brass contacts instead of beryllium copper?

A: Brass is a standard contact material for transistor sockets and provides equivalent electrical performance to beryllium copper in this application. Both materials achieve the required contact resistance and reliability specifications for TO-3 socket operation.

Q: What is the significance of the housing material change from DAP to PBT?

A: Both diallyl phthalate (DAP) and polybutylene terephthalate (PBT) are thermoplastic materials rated UL94 V-0. The PBT housing in the 4516 provides equivalent mechanical and thermal performance for chassis mount applications while offering improved moisture resistance and modern manufacturing advantages.

Q: Is the Keystone Electronics 4516 RoHS compliant?

A: Yes. The 4516 is ROHS3 compliant, whereas the 8080-1G35 is RoHS non-compliant. This compliance advantage makes the 4516 suitable for applications subject to RoHS regulations.

Q: Are there any temperature or environmental limitations when substituting the 4516 for the 8080-1G35?

A: The 8080-1G35 specifies an operating temperature range of -55°C ~ 125°C. The 4516 does not specify an operating temperature range in the provided data. Both components maintain Moisture Sensitivity Level 1 (Unlimited), indicating equivalent environmental performance for standard applications.

Q: What is the inventory status of these components?

A: The 8080-1G35 has 1040 pieces in stock but is obsolete. The Keystone Electronics 4516 has 2200 pieces in stock and is an active product, ensuring long-term availability.
