Key Parameters

Substitute Part Grouping Explanation

The D01-9943246 qualifies as a direct substitute for the D01-9943201 based on the following critical parameters:

• Connector Type: Both parts are SIP/SIL header connectors
• Number of Positions: Both provide 32 positions
• Pitch: Both maintain 0.100" (2.54mm) spacing
• Number of Rows: Both are single-row configurations
• Contact Type: Both feature slotted contacts
• Mounting Type: Both are through-hole mounted
• Termination Method: Both use solder termination
• Contact Finish: Both use tin plating
• Contact Finish Thickness: Both specify 137.8µin (4.60µm)
• Color: Both are black
• Moisture Sensitivity Level: Both are MSL 1 (Unlimited)

The D01-9943246 is the active production equivalent, differing only in product status and RoHS compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The D01-9943246 is the active production equivalent for the obsolete D01-9943201. Both parts are electrically and mechanically identical across all functional parameters. The primary distinction is product status and regulatory compliance: the D01-9943246 carries ROHS3 compliance, whereas the D01-9943201 is RoHS non-compliant. For new designs or ongoing procurement, the D01-9943246 is the appropriate selection due to its active status and enhanced regulatory compliance posture.

Frequently Asked Questions (FAQ)

Q: Are D01-9943201 and D01-9943246 pin-compatible? A: Yes. Both connectors maintain identical pitch (0.100"), position count (32), row configuration (1), and mounting type (through-hole). They are mechanically and electrically interchangeable.

Q: What is the primary reason to transition from D01-9943201 to D01-9943246? A: The D01-9943201 is obsolete. The D01-9943246 is the active production part from Harwin Inc. with identical electrical and mechanical specifications.

Q: Does the RoHS compliance difference affect compatibility? A: No. RoHS compliance is a regulatory classification that does not alter the electrical or mechanical function of the connector. The D01-9943246 offers enhanced compliance status for applications subject to RoHS requirements.

Q: Are there packaging differences between these parts? A: The D01-9943246 is supplied in bulk packaging. Packaging format does not affect connector performance or compatibility.

Q: Can D01-9943201 be used in new designs? A: The D01-9943201 is obsolete. New designs should specify the D01-9943246 to ensure long-term component availability and regulatory compliance.
