Key Parameters

Substitute Part Grouping Explanation

The D01-9933246 qualifies as a direct substitute for the D01-9933201 based on the following critical parameters:

• Identical electrical specifications: 32-position SIP configuration, 0.100" (2.54mm) mating and post pitch, tin-plated brass contacts, 1.5 A current rating, and 23mOhm contact resistance
• Identical mechanical specifications: Through-hole mounting, solder cup termination, polyamide housing material, and -55°C ~ 125°C operating temperature range
• Same manufacturer series: Both parts belong to the D01-993 series from Harwin Inc.
• Active product status: D01-9933246 is currently in active production, providing long-term availability and supply chain continuity

The substitution is based strictly on functional and dimensional equivalence. No performance degradation occurs when replacing the obsolete D01-9933201 with the D01-9933246.

Parameter Comparison

Engineering Selection Recommendations

The D01-9933246 is the appropriate selection for applications currently using or requiring the D01-9933201. The substitute part maintains full electrical and mechanical compatibility while offering the advantage of active product status and current manufacturing support from Harwin Inc.

For new designs or redesigns of existing products, the D01-9933246 should be specified to ensure long-term component availability and supply chain stability. The obsolete status of the D01-9933201 makes continued procurement increasingly difficult; transitioning to the active equivalent eliminates future sourcing constraints.

Both parts share identical REACH compliance status (REACH Unaffected), confirming regulatory equivalence for applications subject to REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can D01-9933246 be used as a direct replacement for D01-9933201 in existing designs?

A: Yes. The D01-9933246 is electrically and mechanically identical to the D01-9933201. All critical parameters—pin count, pitch, contact material, current rating, and operating temperature range—are equivalent. No circuit modifications or PCB redesign is required.

Q: Why is the D01-9933201 listed as obsolete?

A: The D01-9933201 has been discontinued by Harwin Inc. and replaced by the D01-9933246 in the active product line. The D01-9933246 provides the same functionality with ongoing manufacturing support.

Q: Are there any differences in packaging between these parts?

A: The D01-9933201 packaging is listed as unspecified, while the D01-9933246 is supplied in bulk packaging. Both parts use identical through-hole solder cup termination suitable for standard PCB assembly processes.

Q: What is the contact resistance specification, and does it differ between parts?

A: Both parts specify 23mOhm contact resistance, ensuring equivalent electrical performance in signal and power distribution applications.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the D01-9933201 and D01-9933246 operate across the -55°C ~ 125°C temperature range, making them suitable for industrial and extended-temperature applications.

Q: What is the current-carrying capacity of these sockets?

A: Both parts are rated for 1.5 A continuous current, determined by the brass contact material and tin plating specification.
