D9218-46 Equivalent & Substitute Parts

Part Overview

The D9218-46 is an 18-position DIP/DIL header connector with male pin contacts and tin finish, manufactured by Harwin Inc. This connector is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement continuity. The part features through-hole solder termination with 0.100" (2.54mm) pitch and dual-row configuration, standard for legacy DIP applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D9218-46 is determined by strict equivalence in the following parameters:

• Connector Type: DIP/DIL header configuration
• Position Count: 18 positions
• Pitch: 0.100" (2.54mm) center-to-center spacing
• Row Configuration: 2 rows with 0.300" (7.62mm) spacing
• Mounting: Through-hole solder termination
• Compliance: ROHS3 and REACH compliance maintained

The substitute part 150-10-318-00-001000 (Mill-Max Manufacturing Corp.) meets all mechanical and electrical equivalence criteria. Variations in contact type (post vs. male pin) and contact finish (gold vs. tin) do not affect functional interchangeability in standard DIP header applications where contact geometry and pitch are preserved.

Parameter Comparison

Engineering Selection Recommendations

The 150-10-318-00-001000 from Mill-Max Manufacturing Corp. is the qualified substitute for the obsolete D9218-46. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity. The substitute part carries active product status with confirmed inventory availability (934 pcs), providing supply chain reliability for new designs and legacy system support.

Selection of the Mill-Max substitute is supported by mechanical and electrical parameter equivalence across all critical dimensions and electrical characteristics. The transition from tin to gold contact finish and from male pin to post contact geometry does not compromise functional performance in standard DIP header applications where pitch and row spacing are preserved.

Frequently Asked Questions (FAQ)

Q: Can the 150-10-318-00-001000 directly replace the D9218-46 in existing PCB designs?

A: Yes. Both connectors share identical pitch (0.100"), row spacing (0.300"), position count (18), and through-hole solder termination. PCB footprints designed for the D9218-46 are mechanically compatible with the Mill-Max substitute.

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

A: Male pin contacts are designed to insert into female receptacles. Post contacts are designed to accept female pins or wire terminations. In DIP header applications, both contact geometries maintain the same pitch and row spacing, allowing footprint compatibility.

Q: Does the gold finish on the substitute part affect compatibility?

A: No. Gold finish provides enhanced corrosion resistance and solderability compared to tin. The contact finish does not alter mechanical fit or electrical performance in standard solder termination applications.

Q: Are there inventory considerations for the substitute part?

A: The 150-10-318-00-001000 is in active production with 934 pcs available in stock, compared to the obsolete D9218-46 status. This ensures long-term procurement availability for production and support applications.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the D9218-46 and 150-10-318-00-001000 are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status for commercial and industrial applications.
