TE Connectivity AMP Connectors 8-1437504-9 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 8-1437504-9 is a 3-position transistor socket for TO-3 packages with tin-lead plated beryllium copper contacts. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing procurement and design applications. The socket features a closed frame design with chassis mount termination and operates across the temperature range of -55°C to 125°C. Due to its obsolete status, sourcing active alternatives is essential for production continuity and new design implementations.

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 8-1437504-9 is determined by the following critical parameters that must align across candidate parts:

Primary Substitution Criteria:

• Socket type: Transistor, TO-3
• Number of positions: 3 (Oval configuration)
• Mounting type: Chassis Mount
• Termination method: Solder
• Frame design: Closed Frame
• Flammability rating: UL94 V-0
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

Secondary Compatibility Factors:

• Contact finish material (mating side): Tin or Tin-Lead
• Contact material composition: Beryllium Copper or Brass
• Housing material: Phenolic or Polybutylene Terephthalate (PBT)
• Operating temperature range: -55°C to 125°C or equivalent

The Keystone Electronics 4513 satisfies all primary substitution criteria and maintains functional equivalence for TO-3 transistor socket applications.

Engineering Selection Recommendations

The Keystone Electronics 4513 is the qualified substitute for the obsolete TE Connectivity 8-1437504-9. Selection of this alternative is supported by the following engineering factors:

Product Status Alignment: The 4513 maintains active product status, ensuring ongoing availability and supply chain continuity. The 8-1437504-9 is obsolete, making the 4513 the appropriate choice for new designs and production replenishment.

Regulatory and Compliance Equivalence: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements. Both components carry UL94 V-0 flammability ratings, meeting safety standards for electronic applications.

Functional Compatibility: The 4513 provides identical socket configuration for TO-3 transistor packages with 3-position oval contact arrangement. Both parts feature closed frame design, chassis mount termination, and solder connection methodology. Moisture sensitivity level 1 (Unlimited) is maintained across both parts.

Contact and Material Specifications: The 4513 employs tin-plated brass contacts in place of the tin-lead beryllium copper contacts of the 8-1437504-9. Brass contact material provides equivalent electrical performance for transistor socket applications. The PBT housing material of the 4513 offers superior thermal and mechanical properties compared to phenolic, with maintained UL94 V-0 rating.

Trade Considerations: The 4513 is available in bulk packaging with higher inventory levels (1815 pieces), supporting production requirements. The contact resistance specification is not provided for the 4513; however, brass contacts with tin plating deliver performance suitable for low-signal transistor socket applications.

Frequently Asked Questions (FAQ)

Q: Can the Keystone Electronics 4513 directly replace the TE Connectivity 8-1437504-9 in existing designs?

A: Yes. Both parts are 3-position TO-3 transistor sockets with identical pin configuration, chassis mount design, and closed frame construction. The 4513 maintains the same electrical and mechanical interface requirements.

Q: What is the primary difference between these two socket designs?

A: The main differences are contact material composition and housing material. The 8-1437504-9 uses beryllium copper contacts with tin-lead plating and phenolic housing. The 4513 uses brass contacts with tin plating and PBT housing. Both materials provide equivalent performance for transistor socket applications while maintaining UL94 V-0 flammability compliance.

Q: Are there temperature range differences between these parts?

A: The 8-1437504-9 specifies an operating temperature range of -55°C to 125°C. The 4513 does not provide an explicit operating temperature specification in the available data. For applications requiring confirmed temperature performance, the 8-1437504-9 specification should be referenced.

Q: Why is the 8-1437504-9 marked as obsolete?

A: Obsolete status indicates the part is no longer manufactured by TE Connectivity. The Keystone Electronics 4513 is an active equivalent that fulfills the same functional requirements for new and ongoing production applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 8-1437504-9 and 4513 are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.

Q: What is the contact resistance specification for the 4513?

A: The contact resistance value is not provided in the available specifications for the Keystone Electronics 4513. The TE Connectivity 8-1437504-9 specifies 25mOhm contact resistance. For applications with specific contact resistance requirements, verification against actual component measurements is necessary.

Q: Can these sockets accommodate different TO-3 package variants?

A: Both sockets are designed for standard TO-3 transistor packages with 3-position oval contact configuration. Compatibility is limited to components matching this specific package geometry.

Q: What packaging options are available for the substitute part?

A: The Keystone Electronics 4513 is supplied in bulk packaging. The TE Connectivity 8-1437504-9 packaging specification is not provided in the available data.
