Key Parameters

Substitute Part Grouping Explanation

The 74977-103001LF qualifies as a direct substitute based on identical electrical and mechanical parameters: 108 positions, 0.079" (2.00mm) pitch, 5-row configuration, through-hole mounting, press-fit termination, and identical contact layout (90 signal, 18 ground). Both parts maintain the same current rating (1A), operating temperature range (-55°C to 105°C), and material flammability rating (UL94 V-0).

The primary distinction between these parts is product status and compliance certification. The 74977-103001LF is active and RoHS compliant, whereas the original 74977-103001 is obsolete and RoHS non-compliant. The substitute is packaged in tube format, compared to the original's unspecified packaging.

Parameter Comparison

Engineering Selection Recommendations

The 74977-103001LF is the appropriate selection for new designs and ongoing system support. This part maintains complete electrical and mechanical compatibility with the obsolete 74977-103001 while offering active product status and RoHS compliance certification. The substitute's active status ensures continued availability and manufacturer support. For applications requiring RoHS compliance, the 74977-103001LF is mandatory. The tube packaging of the substitute provides standard handling and storage benefits for production environments.

Frequently Asked Questions (FAQ)

Q: Are the 74977-103001 and 74977-103001LF electrically identical? A: Yes. Both parts share identical electrical specifications: 108 positions, 1A current rating, -55°C to 105°C operating temperature range, and UL94 V-0 flammability rating.

Q: Are the mechanical dimensions and mounting characteristics the same? A: Yes. Both parts feature identical mechanical specifications: 0.079" (2.00mm) pitch, 5-row configuration, through-hole mounting, press-fit termination, and 90 signal/18 ground contact layout.

Q: What is the primary reason to use the 74977-103001LF instead of the 74977-103001? A: The 74977-103001 is obsolete, while the 74977-103001LF is active. The substitute also carries RoHS compliance certification, whereas the original does not.

Q: Can the 74977-103001LF be used as a direct replacement in existing assemblies? A: Yes. Identical pin configuration, pitch, and mounting type ensure direct compatibility in existing PCB designs.
