Parameter Comparison

Engineering Selection Recommendations

The 98401-101-46LF represents an active product alternative to the obsolete M20-8762346. Both components maintain identical electrical and mechanical specifications for the critical parameters governing rectangular connector header compatibility: 46-position, 2-row configuration at 0.100" pitch with 3A current rating and UL94 V-0 flammability compliance.

The substitute offers an extended operating temperature range (-65°C to 130°C versus -40°C to 105°C) and improved contact finish with gold plating, providing enhanced environmental performance. Both components carry equivalent moisture sensitivity ratings and comply with applicable regulatory standards (RoHS and REACH).

Selection of the 98401-101-46LF is supported by active product status and current manufacturing availability, ensuring long-term supply chain continuity compared to the obsolete M20-8762346.

Frequently Asked Questions (FAQ)

Q: What makes the 98401-101-46LF a suitable substitute for the M20-8762346?

A: Both connectors share identical core specifications: 46 positions, 2 rows, 0.100" (2.54mm) pitch, male pin contact type, surface mount configuration, and 3A current rating. These parameters define functional compatibility for rectangular connector headers in board-to-board applications.

Q: Are there physical differences between these connectors?

A: Minor dimensional variations exist. The 98401-101-46LF has a contact length of 0.230" (5.84mm) compared to 0.228" (5.80mm) for the M20-8762346, and an insulation height of 0.084" (2.14mm) versus 0.100" (2.54mm). These differences fall within acceptable tolerances for standard PCB mounting applications.

Q: What is the difference in contact finish between these parts?

A: The M20-8762346 uses tin plating on brass contacts, while the 98401-101-46LF features gold plating (GXT™) on phosphor bronze contacts. Gold plating provides superior corrosion resistance and contact reliability in demanding environments.

Q: Does the substitute support the same electrical specifications?

A: Yes. Both connectors are rated for 3A per contact and UL94 V-0 flammability compliance. The 98401-101-46LF supports an extended operating temperature range of -65°C to 130°C, compared to -40°C to 105°C for the M20-8762346.

Q: What packaging is available for the substitute?

A: The 98401-101-46LF is supplied in bag packaging, with 758 pieces currently in stock as new original inventory.
