Key Parameters

Substitute Part Grouping Explanation

Substitution of the SA649000 is determined by the following critical parameters that must remain constant:

• Number of Positions: 64 (2 x 32) configuration
• Type: DIP socket with 0.9" (22.86mm) row spacing
• Pitch - Mating: 0.100" (2.54mm) standard DIP pitch
• Contact Finish - Mating: Gold plating on beryllium copper
• Mounting Type: Through hole solder termination
• Housing Material: Thermoplastic with glass reinforcement

The substitute part 110-87-964-41-001101 (Preci-Dip) satisfies all critical substitution criteria. Both parts maintain identical mechanical and electrical interface specifications for 64-position DIP socket applications. The substitute part is classified as active product status, ensuring ongoing availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The 110-87-964-41-001101 (Preci-Dip) is the qualified substitute for the obsolete SA649000. Both parts maintain identical mechanical and electrical interface specifications for 64-position DIP socket applications and are ROHS3 compliant.

The substitute part is classified as active product status, ensuring long-term availability and supply chain support. The extended operating temperature range (-55°C ~ 125°C) of the substitute part provides enhanced thermal performance compared to the original part specification (-40°C ~ 105°C).

Design applications requiring the full 3 A current rating of the original SA649000 must evaluate the 1 A current rating of the substitute part. Applications operating within the 1 A current specification are directly compatible. The increased contact resistance (10 mOhm versus 4 mOhm) must be evaluated for applications with stringent voltage drop requirements.

Frequently Asked Questions (FAQ)

Q: Can the 110-87-964-41-001101 be used as a direct replacement for the SA649000?

A: Yes, for applications operating within the 1 A current specification. Both parts maintain identical 64-position DIP socket configuration, 0.100" (2.54mm) pitch, gold-plated beryllium copper mating contacts, and through-hole solder termination. Applications requiring the full 3 A current rating of the original part must evaluate the reduced current specification of the substitute.

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

A: The substitute part (Preci-Dip) offers an extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 105°C), active product status for ongoing availability, and different housing material (PCT polyester versus thermoplastic polyester). The substitute part has a lower current rating (1 A versus 3 A) and higher contact resistance (10 mOhm versus 4 mOhm).

Q: Are both parts RoHS compliant?

A: Yes, both the SA649000 and 110-87-964-41-001101 are ROHS3 compliant.

Q: What is the significance of the product status difference?

A: The SA649000 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 110-87-964-41-001101 is classified as active, ensuring ongoing production, supply chain support, and long-term component availability for new designs and production runs.

Q: Are there packaging differences between these parts?

A: The SA649000 is supplied without specified packaging designation. The 110-87-964-41-001101 is supplied in bulk packaging. Both parts are suitable for through-hole PCB assembly processes.
