SA649040 64-Position DIP Socket - Equivalent & Substitute Parts

Part Overview

The SA649040 is a 64-position DIP socket manufactured by On Shore Technology Inc., designed for IC and transistor applications with gold-plated contacts and through-hole mounting. This component features a 0.9" (22.86mm) row spacing configuration with beryllium copper mating contacts and brass posts. The product is currently obsolete, making identification of compatible substitute components essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SA649040 is determined by strict equivalence across the following critical parameters:

• Position Count & Configuration: 64 positions in 2 x 32 arrangement
• Row Spacing: 0.9" (22.86mm) center-to-center distance
• Pitch - Mating: 0.100" (2.54mm) standard DIP spacing
• Mounting Method: Through-hole solder termination
• Contact Finish - Mating: Gold plating on mating contacts
• Housing Material Compatibility: Thermoplastic or polyester-based materials with glass reinforcement
• Regulatory Compliance: ROHS3 compliance and UL94 V-0 flammability rating

The substitute part 110-87-964-41-001101 (Preci-Dip) meets all critical dimensional and electrical requirements for direct substitution while maintaining active product status.

Parameter Comparison

Engineering Selection Recommendations

The 110-87-964-41-001101 (Preci-Dip) is the qualified substitute for the obsolete SA649040. Both components maintain ROHS3 compliance and UL94 V-0 flammability certification, ensuring regulatory equivalence for applications requiring these standards.

The substitute provides an extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 105°C), offering improved thermal performance for demanding environments. However, the substitute exhibits a reduced current rating (1 A versus 3 A) and higher contact resistance (10 mOhm versus 4 mOhm). These electrical differences require evaluation against specific application requirements.

The post contact finish differs (tin versus gold), which may affect long-term reliability in corrosive environments or high-cycle insertion applications. The substitute's active product status ensures ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 110-87-964-41-001101 be used as a direct replacement for SA649040?

A: Yes, for applications within the substitute's electrical ratings. Both components share identical 64-position DIP configuration, 0.9" row spacing, 0.100" mating pitch, and gold-plated mating contacts. Verify that your application does not exceed the substitute's 1 A current rating or require the original 3 A specification.

Q: What are the key differences between these two sockets?

A: The primary differences are current rating (3 A vs. 1 A), contact resistance (4 mOhm vs. 10 mOhm), operating temperature range (-40°C to 105°C vs. -55°C to 125°C), and post contact finish (gold vs. tin). The substitute offers wider temperature performance but lower current capacity.

Q: Are both components RoHS compliant?

A: Yes, both SA649040 and 110-87-964-41-001101 are ROHS3 compliant and carry UL94 V-0 flammability ratings, meeting equivalent regulatory requirements.

Q: Does the difference in post contact finish affect compatibility?

A: The post finish (gold vs. tin) does not affect mechanical fit or basic electrical function. However, tin-plated posts may exhibit different corrosion resistance characteristics in specific environmental conditions compared to gold-plated posts.

Q: Why is the SA649040 marked as obsolete?

A: The SA649040 is no longer manufactured by On Shore Technology Inc. The 110-87-964-41-001101 represents the active equivalent from Preci-Dip, ensuring continued component availability for new designs and system support.
