Key Parameters

Substitute Part Grouping Explanation

Substitution for the 89073-121 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 24 positions, 4 rows, 0.079" (2.00mm) pitch
• Electrical Characteristics: 1A current rating, gold contact finish with 30.0µin thickness
• Mechanical Interface: Through-hole mounting, press-fit termination
• Environmental Compliance: UL94 V-0 flammability rating, -55°C to 125°C operating range, MSL 1

The substitute part 89073-121LF maintains identical electrical and mechanical specifications while offering improved regulatory compliance status. Both parts belong to the Amphenol ICC Metral® series and share the same base product number (89073).

Parameter Comparison

Engineering Selection Recommendations

The 89073-121LF serves as the direct active substitute for the obsolete 89073-121. Both connectors are electrically and mechanically identical across all specified parameters, ensuring pin-for-pin compatibility in PCB applications.

The 89073-121LF offers the following advantages for new designs and ongoing production:

• Active Product Status: Ensures continued availability and manufacturer support
• RoHS Compliance: Meets current regulatory requirements for lead-free manufacturing
• REACH Compliance: Addresses European chemical safety regulations
• Standardized Packaging: Supplied in tube packaging for automated assembly processes

For legacy system repairs requiring the original 89073-121, the 89073-121LF provides functional equivalence without design modification. The connector maintains the same footprint, pin configuration, and electrical performance across all operating conditions.

Frequently Asked Questions (FAQ)

Q: Are the 89073-121 and 89073-121LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications: 24 positions, 4-row configuration, 0.079" (2.00mm) pitch, through-hole mounting, and press-fit termination. PCB footprints are identical.

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

A: The primary differences are product status and regulatory compliance. The 89073-121 is obsolete and RoHS non-compliant. The 89073-121LF is an active product with RoHS and REACH compliance. Electrical and mechanical specifications are identical.

Q: Can I use the 89073-121LF in applications originally designed for the 89073-121?

A: Yes. The 89073-121LF is a direct substitute with identical electrical performance (1A current rating, -55°C to 125°C operating range) and mechanical interface. No circuit design changes are required.

Q: What does the "LF" suffix indicate?

A: The "LF" suffix typically indicates lead-free manufacturing and RoHS compliance in Amphenol ICC part numbering conventions.

Q: Are there packaging differences between these parts?

A: The 89073-121 packaging is not specified. The 89073-121LF is supplied in tube packaging, which is standard for automated PCB assembly processes.

Q: What is the current rating for this connector?

A: Both the 89073-121 and 89073-121LF are rated for 1A per contact at operating temperatures between -55°C and 125°C.

Q: Is this connector suitable for high-temperature applications?

A: The connector is rated for continuous operation up to 125°C and maintains UL94 V-0 flammability rating across the full operating temperature range.
