Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74770-102 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 96-position receptacle with female sockets
• Pitch and Geometry: 0.079" (2.00mm) pitch with 8-row arrangement
• Mounting and Termination: Board edge mounting with through-hole, right-angle press-fit termination
• Electrical Performance: 1A current rating and UL94 V-0 flammability rating
• Environmental Specifications: -55°C to 125°C operating temperature range
• Contact System: Gold-plated contacts at 30.0µin (0.76µm) thickness

The 74770-102LF qualifies as a direct substitute based on identical electrical, mechanical, and environmental specifications. The primary distinction is product status and regulatory compliance, not functional capability.

Parameter Comparison

Engineering Selection Recommendations

The 74770-102LF is the direct functional equivalent of the 74770-102 and is the appropriate selection for new designs and production applications. The 74770-102LF maintains identical electrical and mechanical specifications while offering the following advantages:

• Active Product Status: The 74770-102LF is actively manufactured and supported, ensuring long-term supply availability and technical support.
• RoHS Compliance: The 74770-102LF meets RoHS requirements, satisfying regulatory mandates for new equipment in most jurisdictions.
• Regulatory Alignment: REACH affected status indicates compliance with current chemical substance regulations.

For legacy system maintenance where the original 74770-102 is required, the part remains available in current inventory. However, for new production and forward-looking designs, the 74770-102LF is the recommended selection based on product lifecycle and compliance status.

Frequently Asked Questions (FAQ)

Q: Can the 74770-102LF be used as a direct replacement for the 74770-102 in existing designs?

A: Yes. The 74770-102LF is electrically and mechanically identical to the 74770-102. All connector specifications, including pitch, position count, current rating, temperature range, and contact finish, are equivalent. The parts are interchangeable at the board level.

Q: What is the significance of the "LF" suffix in the 74770-102LF part number?

A: The "LF" designation indicates lead-free construction and RoHS compliance. This reflects the manufacturing process and material composition changes implemented to meet current environmental regulations.

Q: Are there packaging differences between the 74770-102 and 74770-102LF?

A: Yes. The 74770-102 is supplied in bulk packaging, while the 74770-102LF is supplied in tube packaging. This difference does not affect connector functionality or performance.

Q: Why is the 74770-102 classified as obsolete?

A: The obsolete status reflects the manufacturer's transition to RoHS-compliant production. The 74770-102LF represents the current active product line for this connector configuration.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts maintain identical current ratings (1A), operating temperature ranges (-55°C to 125°C), and contact specifications. Electrical performance is equivalent.

Q: What is the inventory status for these parts?

A: The 74770-102 has 1178 pieces in stock (new original). The 74770-102LF has 1016 pieces in stock (new original). Both are available for immediate procurement.
