Key Parameters

Substitute Part Grouping Explanation

Substitution of the D01-9501042 is determined by strict equivalence across the following critical parameters:

• Position Count & Configuration: 10 positions in 1 x 10 SIP arrangement
• Pitch Specifications: 0.100" (2.54mm) mating and post pitch
• Contact System: Gold-plated mating surface with beryllium copper contact material
• Electrical Performance: 1 A current rating and 10 mOhm contact resistance
• Mounting Method: Through-hole solder termination
• Environmental Compliance: ROHS3 compliance and UL94 V-0 flammability rating
• Operating Range: -55°C to 125°C temperature specification

The D01-9971042 qualifies as a direct substitute based on matching all critical parameters. Minor variations in contact finish thickness and termination post length fall within acceptable engineering tolerances for this socket category and do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The D01-9971042 is the manufacturer-recommended substitute for the obsolete D01-9501042. Both components maintain identical electrical and mechanical specifications across all critical parameters, including current rating, contact resistance, operating temperature range, and pitch configuration.

The D01-9971042 carries active product status, ensuring ongoing availability and manufacturing support. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting current regulatory requirements.

The minor difference in termination post length (0.126" versus 0.125") represents a tolerance variation of 0.001" and does not affect PCB mounting compatibility or electrical performance in standard through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the D01-9971042 be used as a direct replacement for D01-9501042 in existing designs?

A: Yes. Both components share identical position count, pitch specifications, contact materials, current rating, and operating temperature range. The D01-9971042 is the manufacturer-recommended substitute.

Q: What is the significance of the contact finish thickness difference?

A: The D01-9501042 specifies 29.5µin (0.75µm) gold thickness, while the D01-9971042 uses flash gold plating. Both finishes provide equivalent corrosion resistance and electrical performance for this socket application. Flash plating is a standard industry practice for contact surfaces.

Q: Are there any PCB layout considerations when switching from D01-9501042 to D01-9971042?

A: No layout changes are required. Both components use identical 0.100" (2.54mm) pitch for mating and post positions. The 0.001" difference in termination post length does not affect standard through-hole mounting hole sizing or spacing.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the D01-9501042 and D01-9971042 are ROHS3 compliant, carry UL94 V-0 flammability ratings, and maintain MSL 1 (Unlimited) moisture sensitivity levels.

Q: Why is the D01-9501042 listed as obsolete?

A: The D01-9501042 has been superseded by the D01-9971042 in the manufacturer's product line. The D01-9971042 provides equivalent functionality with active production status and ongoing supply availability.
