Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 12-820-90C is determined by strict alignment of the following critical parameters:

• Number of positions and grid configuration: 12 (2 x 6)
• DIP socket type with 0.3" (7.62mm) row spacing
• Mating pitch: 0.100" (2.54mm)
• Gold-plated mating contacts
• Through-hole, right-angle, horizontal mounting orientation
• Closed-frame design
• Solder termination
• Current rating: 3 A minimum
• Operating temperature range compatibility

The substitute part 299-93-312-11-001000 (Mill-Max Manufacturing Corp.) meets all critical substitution criteria. Variations in post contact finish material, housing material composition, and termination post length do not preclude substitution when these parameters fall within acceptable engineering tolerances for the application.

Parameter Comparison

Engineering Selection Recommendations

The 12-820-90C (Aries Electronics) is ROHS3 compliant and maintains active production status. The substitute part 299-93-312-11-001000 (Mill-Max Manufacturing Corp.) is RoHS non-compliant and should be selected only when RoHS compliance is not a regulatory requirement for the application.

The Mill-Max substitute provides an extended operating temperature range (-55°C to 125°C versus -55°C to 105°C), which may be advantageous for applications requiring higher temperature performance. The termination post length difference (0.126" versus 0.140") must be evaluated against PCB design specifications to ensure proper solder joint formation and mechanical clearance.

Both parts share identical mating contact specifications, current ratings, and moisture sensitivity classifications, confirming functional equivalence for standard DIP socket applications.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 299-93-312-11-001000 be used as a direct replacement for the Aries 12-820-90C?

A: Yes, for applications where RoHS compliance is not required. Both parts share identical pin counts, pitch specifications, mating contact materials and finishes, and current ratings. The primary differences are RoHS compliance status and operating temperature range.

Q: What is the significance of the termination post length difference?

A: The Aries part has a post length of 0.140" (4.66mm) while the Mill-Max part is 0.126" (3.20mm). This 0.014" difference must be verified against PCB hole depth and solder fillet requirements to ensure adequate mechanical strength and electrical connection quality.

Q: Does the post contact finish difference affect substitution?

A: The Aries part uses tin-plated posts while the Mill-Max part uses tin-lead plating. Both finishes provide adequate corrosion resistance and solderability. Selection depends on application-specific requirements regarding lead content and environmental regulations.

Q: Are both parts suitable for high-temperature applications?

A: The Mill-Max substitute supports operation to 125°C, exceeding the Aries part's 105°C maximum. For applications requiring sustained operation above 105°C, the Mill-Max part provides extended thermal capability.

Q: What packaging differences exist between these parts?

A: The Aries 12-820-90C is supplied in bulk packaging, while the Mill-Max 299-93-312-11-001000 is supplied in tube packaging. Packaging format does not affect electrical or mechanical performance.
