D9948-01 Equivalent & Substitute Parts

Part Overview

The D9948-01 is a 48-position DIP/DIL header connector with male pins, manufactured by Harwin Inc. This through-hole solder-terminated connector features a 0.100" (2.54mm) pitch and 0.600" (15.24mm) row spacing in a 2-row configuration. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D9948-01 is determined by the following critical parameters that must remain consistent:

• Connector Type: DIP/DIL header configuration
• Number of Positions: 48-position requirement
• Pitch: 0.100" (2.54mm) standard spacing
• Number of Rows: 2-row layout
• Row Spacing: 0.600" (15.24mm) center-to-center distance
• Mounting Type: Through-hole PCB mounting
• Termination Method: Solder connection

The substitute part 150-90-648-00-001000 from Mill-Max Manufacturing Corp. satisfies all these critical parameters. The primary difference is the contact type (post versus male pin) and contact finish composition (tin-lead versus tin), which are acceptable variations within the DIP/DIL header connector category for equivalent functional performance.

Parameter Comparison

Engineering Selection Recommendations

The 150-90-648-00-001000 from Mill-Max Manufacturing Corp. is the designated substitute for the obsolete D9948-01. This selection is based on:

• Active Product Status: The substitute maintains active manufacturing status, ensuring long-term availability and supply chain continuity.
• Compliance Alignment: Both parts share identical RoHS non-compliance status and REACH unaffected classification, maintaining regulatory consistency in applications where these certifications apply.
• Functional Equivalence: All critical dimensional and electrical parameters match the original specification, including pitch, row spacing, position count, and through-hole mounting configuration.
• Inventory Availability: The substitute part is available in production quantities (1000 pcs new original in stock), supporting immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Can the 150-90-648-00-001000 be used as a direct replacement for the D9948-01?

A: Yes. Both connectors share identical pitch (0.100"), row spacing (0.600"), position count (48), and mounting configuration (through-hole solder). The contact type difference (post versus male pin) and contact finish composition (tin-lead versus tin) do not prevent functional equivalence in DIP/DIL header applications.

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

A: Male pin and post contacts are both acceptable contact geometries for DIP/DIL header connectors. Both types are designed for solder termination and through-hole PCB mounting. The selection between them depends on mating connector design and application requirements, not on fundamental compatibility.

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS non-compliant and REACH unaffected. They share identical regulatory classification, making them suitable for applications with equivalent compliance requirements.

Q: What does the packaging difference (tube for the substitute) mean for procurement?

A: The Mill-Max part is supplied in tube packaging, which is standard for production quantities. This packaging method does not affect the connector's electrical or mechanical performance and is typical for active production components.

Q: Why is the D9948-01 listed as obsolete?

A: Obsolete status indicates that Harwin Inc. has discontinued manufacturing this part. The substitute part from Mill-Max provides equivalent functionality with active production support.
