Key Parameters

Substitute Part Grouping Explanation

Substitution of the 8058-1G30 is determined by the following critical parameters that must align across equivalent parts:

Core Compatibility Parameters:

• Type: Transistor, TO-5 socket
• Number of Positions: 4 (Round)
• Termination: Solder
• Features: Closed Frame
• Moisture Sensitivity Level: 1 (Unlimited)

Functional Equivalence Parameters:

• Contact finish materials and post materials must support equivalent electrical performance
• Mounting configuration (panel mount vs. chassis mount) affects board integration but does not prevent functional substitution
• Housing material differences are acceptable provided mechanical fit and electrical isolation are maintained
• Operating temperature range must support the application requirements

The Keystone Electronics 4591 qualifies as a substitute part based on matching core compatibility parameters. Differences in contact finish (tin vs. gold), contact material composition, mounting type (chassis mount vs. panel mount), and housing material (polyester, glass filled vs. PTFE) represent design variations that do not prevent functional substitution in TO-5 transistor socket applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The Keystone Electronics 4591 is the identified substitute for the obsolete TE Connectivity AMP Connectors 8058-1G30. Selection between these parts is determined by application-specific requirements and compliance mandates:

For Active Production Requirements: The 4591 is the appropriate selection due to its active product status. The 8058-1G30 is obsolete and subject to availability constraints. Both parts maintain RoHS compliance (RoHS Compliant vs. ROHS3 Compliant), satisfying regulatory requirements for new designs and manufacturing.

Contact Finish Considerations: The 8058-1G30 features gold-plated mating contacts with beryllium copper material. The 4591 features tin-plated mating contacts with brass material. Both configurations support solder termination and closed frame design. Contact finish selection reflects application voltage, current, and environmental exposure requirements not specified in the provided parameters.

Mounting Configuration: The 8058-1G30 is panel mount; the 4591 is chassis mount. This difference affects PCB integration methodology but does not prevent functional substitution. Board layout and mechanical mounting design must accommodate the selected mounting type.

Housing Material: The 8058-1G30 uses PTFE housing; the 4591 uses polyester, glass filled with UL94 V-0 flammability rating. Both materials provide electrical isolation and mechanical support for TO-5 transistor sockets. Housing material selection reflects environmental and thermal management requirements.

Frequently Asked Questions (FAQ)

Q: Can the Keystone Electronics 4591 directly replace the TE Connectivity 8058-1G30 in existing designs?

A: The 4591 is functionally equivalent for TO-5 transistor socket applications. Direct replacement requires verification of mounting configuration compatibility (panel mount vs. chassis mount) and contact finish suitability for the specific application environment. Both parts maintain identical position count (4 round), termination method (solder), and frame design (closed).

Q: What is the significance of the contact finish difference between gold and tin?

A: Contact finish affects electrical performance in specific application environments. Gold provides enhanced corrosion resistance and lower contact resistance in low-signal applications. Tin offers cost efficiency and adequate performance in standard industrial applications. Selection depends on application voltage, current, and environmental exposure specifications not provided in the component parameters.

Q: Does the housing material difference affect electrical performance?

A: Housing material differences (PTFE vs. polyester, glass filled) do not affect electrical performance of the socket contacts. Both materials provide adequate electrical isolation and mechanical support. Housing material selection reflects thermal management, flammability rating requirements, and environmental exposure considerations specific to the application.

Q: Why is the 8058-1G30 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by TE Connectivity. The 4591 is an active equivalent part available for new procurement and production requirements.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The 8058-1G30 is RoHS Compliant; the 4591 is ROHS3 Compliant. Both maintain Moisture Sensitivity Level 1 (Unlimited). The 8058-1G30 is REACH Affected; the 4591 is REACH Unaffected. Compliance selection depends on regulatory requirements for the target market and application.

Q: What is the inventory status for these parts?

A: The 8058-1G30 has 901 pieces in stock (new original). The 4591 has 2917 pieces in stock (new original, bulk packaging). Inventory availability should be verified at time of procurement.
