Aries Electronics 20-0513-11 SIP Socket Equivalent & Substitute Parts

Part Overview

The Aries Electronics 20-0513-11 is a 20-position SIP (Single In-line Package) socket designed for IC and transistor applications. This through-hole connector features gold-plated beryllium copper mating contacts and brass posts, providing reliable electrical connections in standard 0.100" (2.54mm) pitch configurations. The part is currently active in production with 866 units in stock. Alternative components may be required due to inventory constraints, application-specific requirements, or design revisions necessitating connector type variations.

Key Parameters

Substitute Part Grouping Explanation

The Mill-Max Manufacturing Corp. 310-99-120-41-001000 qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Number of Positions: 20
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Current Rating: 3 A
• Material Flammability Rating: UL94 V-0
• Contact Material - Mating: Beryllium Copper
• Termination Post Length: 0.125" (3.18mm)

Connector Type Variation: The substitute part is classified as a Rectangular Receptacle Connector (Board to Board) rather than a dedicated SIP socket. This represents a functional alternative for applications requiring 20-position, 0.100" pitch through-hole connectivity with equivalent electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (20-0513-11): Select the Aries Electronics 20-0513-11 for applications requiring ROHS3 compliance. This part maintains active production status and offers gold contact finish for enhanced corrosion resistance and long-term reliability in demanding environments.

Substitute Part (310-99-120-41-001000): The Mill-Max 310-99-120-41-001000 is suitable for applications where RoHS compliance is not a requirement. This part provides equivalent electrical performance and mechanical compatibility with the primary part. The tin-lead contact finish and specified operating temperature range (-55°C ~ 125°C) support standard industrial applications. Note that this substitute is RoHS non-compliant and should be evaluated against project compliance requirements.

Compliance Considerations: Applications subject to RoHS3 regulations must use the Aries Electronics part. Applications without RoHS requirements may utilize either part based on inventory availability and cost considerations.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 310-99-120-41-001000 directly replace the Aries 20-0513-11?

A: Yes, for applications not requiring RoHS3 compliance. Both parts share identical pitch (0.100"), position count (20), current rating (3 A), and termination post length (0.125"). The primary differences are contact finish (gold vs. tin-lead) and RoHS compliance status.

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

A: The Aries part features gold plating (10.0µin thickness) on mating contacts, providing superior corrosion resistance. The Mill-Max part uses tin-lead finish (100.0µin thickness on mating contacts). Gold finish is preferred for long-term reliability and low-wear applications, while tin-lead is acceptable for standard industrial use.

Q: Are there mechanical compatibility concerns?

A: No. Both parts are through-hole mounted with identical 0.100" (2.54mm) pitch and 0.125" (3.18mm) post length, ensuring direct PCB footprint compatibility.

Q: What packaging differences exist?

A: The Aries part is supplied in bulk packaging, while the Mill-Max part is supplied in tube packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Which part should be selected for new designs?

A: For new designs subject to RoHS3 regulations, specify the Aries Electronics 20-0513-11. For designs without RoHS requirements, either part is acceptable based on availability and cost analysis.
