Key Parameters

Substitute Part Grouping Explanation

Substitution of the D9948-46 is determined by strict equivalence across the following critical parameters:

• Connector type classification (DIP/DIL header)
• Position count (48 positions)
• Row configuration (2 rows)
• Pitch spacing (0.100" / 2.54mm)
• Row spacing (0.600" / 15.24mm)
• Mounting method (through hole)
• Termination type (solder)
• Compliance certifications (ROHS3, REACH Unaffected)

The primary substitute, 150-10-648-00-001000 from Mill-Max Manufacturing Corp., maintains full mechanical and electrical compatibility across all these parameters. The contact finish differs (gold versus tin), which represents an enhancement in corrosion resistance and contact reliability rather than a functional incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The 150-10-648-00-001000 from Mill-Max Manufacturing Corp. is the designated substitute for the obsolete D9948-46. Both components maintain identical mechanical footprints and electrical specifications across all critical parameters. The substitute part carries active product status, ensuring long-term availability and supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The gold contact finish of the substitute provides enhanced durability and corrosion resistance compared to the tin finish of the original part, representing a technical improvement suitable for applications requiring extended operational life or exposure to challenging environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the 150-10-648-00-001000 be used as a direct replacement for D9948-46?

A: Yes. Both connectors share identical mechanical dimensions, pitch spacing, row configuration, and solder termination specifications. The components are mechanically and electrically interchangeable in through-hole PCB applications.

Q: What is the difference between male pin and post contact types?

A: Both contact types function identically in DIP/DIL header applications. The terminology reflects manufacturing design variations; both establish equivalent electrical connections when mated with standard 0.100" pitch receptacles.

Q: Does the gold finish of the substitute affect compatibility?

A: No. The gold contact finish is a material enhancement that improves corrosion resistance and contact reliability. It does not alter mechanical fit or electrical performance in standard applications.

Q: Are both parts suitable for new designs?

A: The D9948-46 is obsolete and unsuitable for new designs. The 150-10-648-00-001000 carries active product status and is the appropriate selection for new applications requiring 48-position DIP/DIL header connectors with 0.100" pitch spacing.

Q: What packaging is available for the substitute part?

A: The 150-10-648-00-001000 is supplied in tube packaging, suitable for both manual and automated assembly processes.
