Key Parameters

Substitute Part Grouping Explanation

The Mill-Max Manufacturing Corp. part number 299-93-320-10-001000 qualifies as a functional equivalent based on the following critical parameters:

• Identical 20-position (2 x 10) DIP configuration
• Matching 0.3" (7.62mm) row spacing
• Identical 0.100" (2.54mm) mating and post pitch
• Gold-plated beryllium copper mating contacts
• Identical 3 A current rating
• Through-hole, right-angle, horizontal mounting orientation
• Closed frame design
• Solder termination

Substitution is valid where these core electrical and mechanical parameters are required. Differences in secondary specifications (housing material, post finish composition, flammability rating, and temperature range maximum) do not affect functional interchangeability for standard DIP socket applications.

Parameter Comparison

Engineering Selection Recommendations

Both parts are active products with unlimited moisture sensitivity ratings and identical export classifications. The 20-823-90C is ROHS3 compliant, while the 299-93-320-10-001000 is RoHS non-compliant. Selection between these parts depends on regulatory requirements for the end application. The 20-823-90C is suitable for applications requiring RoHS compliance. The 299-93-320-10-001000 is suitable for applications where RoHS compliance is not mandated. Both parts support identical electrical and mechanical functionality for standard DIP socket applications.

Frequently Asked Questions (FAQ)

Q: Can the 299-93-320-10-001000 be used as a direct replacement for the 20-823-90C?

A: Yes, for applications where RoHS compliance is not required. Both parts share identical pin count, pitch, row spacing, contact materials, and current ratings. The termination post length differs by 0.014" (0.36mm), which may require PCB layout verification for specific designs.

Q: What is the significance of the post finish difference (Tin vs. Tin-Lead)?

A: The post finish composition affects solder joint formation and long-term reliability characteristics. The 20-823-90C uses pure tin, while the 299-93-320-10-001000 uses tin-lead. Both are solder-compatible terminations suitable for standard PCB assembly processes.

Q: Does the operating temperature range difference affect substitution?

A: The 299-93-320-10-001000 supports operation to 125°C, while the 20-823-90C is rated to 105°C. For applications operating within the 20-823-90C range (-55°C to 105°C), both parts are functionally equivalent. Applications requiring operation above 105°C require the 299-93-320-10-001000.

Q: Are there any compliance considerations when selecting between these parts?

A: The 20-823-90C is ROHS3 compliant; the 299-93-320-10-001000 is not. Applications subject to RoHS regulations must use the 20-823-90C. Both parts are REACH unaffected and classified as EAR99 for export purposes.

Q: How do the termination post lengths affect PCB design?

A: The 20-823-90C has a 0.140" (4.66mm) post length; the 299-93-320-10-001000 has a 0.126" (3.20mm) post length. PCB via placement and solder fillet geometry may require adjustment based on the selected part. Verify post length compatibility with your PCB stackup and assembly process.
