Key Parameters

Substitute Part Grouping Explanation

The D01-9972042 qualifies as a direct substitute for D01-9502042 based on the following critical parameters:

• Socket Configuration: Both parts maintain identical 20-position SIP architecture with 1 x 20 pin arrangement
• Pitch Specifications: Mating pitch of 0.100" (2.54mm) and post pitch of 0.100" (2.54mm) are identical
• Contact Materials: Both utilize beryllium copper for mating contacts and brass for posts
• Electrical Performance: Current rating of 1 A and contact resistance of 10mOhm are equivalent
• Environmental Compliance: Both achieve ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 (Unlimited) moisture sensitivity
• Operating Temperature: Identical -55°C ~ 125°C operating range
• Mounting Method: Both are through-hole solder termination components
• Housing Material: Identical polycyclohexylenedimethylene terephthalate (PCT) polyester glass-filled construction

Parameter Comparison

Engineering Selection Recommendations

The D01-9972042 is the appropriate selection for applications currently using or requiring D01-9502042 components. The substitute part maintains full electrical and mechanical compatibility across all critical parameters. The primary distinction is product status: D01-9502042 is obsolete with limited inventory availability, while D01-9972042 is active with substantial stock (15,321 pieces) ensuring supply chain continuity.

Both parts satisfy identical compliance requirements including ROHS3 certification and UL94 V-0 flammability rating. The minor variation in termination post length (0.126" versus 0.125") and mating contact finish thickness (29.5µin versus Flash) does not affect functional performance or PCB compatibility for standard through-hole socket applications.

Frequently Asked Questions (FAQ)

Q: Can D01-9972042 directly replace D01-9502042 in existing designs?

A: Yes. Both parts share identical pin configuration (20-position SIP), pitch specifications (0.100"), contact materials, electrical ratings, and operating temperature range. PCB layouts and component footprints designed for D01-9502042 accommodate D01-9972042 without modification.

Q: What is the difference in contact finish thickness between these parts?

A: D01-9502042 specifies 29.5µin (0.75µm) gold plating on mating contacts, while D01-9972042 uses flash gold plating. Both finishes provide equivalent corrosion resistance and electrical performance for standard signal and power applications within the 1 A current rating.

Q: Are there packaging differences between these parts?

A: D01-9502042 packaging is not specified in available data. D01-9972042 is supplied in tube packaging. This distinction affects handling and storage procedures but does not impact electrical or mechanical compatibility.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both D01-9502042 and D01-9972042 are ROHS3 compliant, achieve UL94 V-0 flammability rating, and carry MSL 1 (Unlimited) moisture sensitivity classification. Both are REACH unaffected and classified under ECCN EAR99.

Q: Why is D01-9502042 listed as obsolete?

A: D01-9502042 has been superseded by D01-9972042 within the Harwin product line. The newer part (D01-997 series) provides the same functionality with active manufacturing status and improved supply availability.
