Key Parameters

Substitute Part Grouping Explanation

The 93239-111LF qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector type, style, and position count remain unchanged (Receptacle, Female Blade Sockets, 8-position)
• Current and voltage ratings are equal or exceed requirements (1A, 1000V)
• Operating temperature range encompasses the original specification (-55°C to 105°C)
• Contact finish specification and thickness are maintained (Gold, 31.5µin)
• Mounting method and termination type are identical (Through Hole, Solder)
• Material flammability rating meets or exceeds the original (UL94 V-0)

The primary distinction between the main part and substitute is product status and regulatory compliance, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 93239-111LF is the direct functional equivalent of the 93239-111. Selection of the substitute part is based on the following factors:

• The 93239-111 is classified as obsolete, limiting availability for new procurement
• The 93239-111LF maintains identical electrical performance, mechanical compatibility, and thermal specifications
• The 93239-111LF is RoHS Compliant, meeting current regulatory requirements for new designs and manufacturing
• Both parts are manufactured by Amphenol ICC within the same Metral® series, ensuring design compatibility
• The 93239-111LF is actively stocked, providing supply chain reliability

For applications requiring the 93239-111, the 93239-111LF is the appropriate replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 93239-111LF be used as a direct replacement for the 93239-111?

A: Yes. Both parts are electrically and mechanically identical. The 93239-111LF is the active production equivalent with improved regulatory compliance.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (obsolete vs. active), RoHS compliance status, and packaging format (bulk vs. tube). Electrical and mechanical specifications are identical.

Q: Are there any design modifications required when switching from 93239-111 to 93239-111LF?

A: No design modifications are required. The parts are pin-compatible and functionally equivalent.

Q: What does the "LF" suffix indicate?

A: The "LF" suffix indicates Lead-Free composition, which aligns with RoHS compliance requirements.

Q: Is the 93239-111LF suitable for high-temperature applications?

A: Yes. The operating temperature range of -55°C to 105°C is identical to the original part, supporting the same thermal requirements.

Q: What is the current rating for this connector?

A: The current rating is 1A per contact at 1000V maximum voltage.

Q: Does packaging format affect electrical performance?

A: No. The tube packaging of the 93239-111LF provides improved handling and storage compared to bulk packaging but does not affect electrical or mechanical performance.
