SIP1X20-041BLF Equivalent & Substitute Parts

Part Overview

The SIP1X20-041BLF is a 20-position SIP (Single In-line Package) socket manufactured by Amphenol ICC (FCI), designed for IC and transistor applications. This component features gold-plated mating contacts and through-hole solder termination. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support, repair, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SIP1X20-041BLF is determined by the following critical parameters:

Primary Compatibility Criteria:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 20
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish - Mating: Gold
• Contact Material - Mating: Beryllium Copper
• Termination Post Length: 0.125" (3.18mm)
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts identified maintain these core electrical and mechanical parameters, ensuring functional compatibility in applications originally designed for the SIP1X20-041BLF. Both substitute parts are manufactured by Mill-Max Manufacturing Corp. and carry active product status with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

310-43-120-41-001000 (Primary Substitute)

This Mill-Max receptacle connector provides the closest functional equivalence to the SIP1X20-041BLF. It maintains identical pitch (0.100" / 2.54mm), position count (20), contact finish specifications (gold mating, tin post), contact finish thicknesses, termination post length (0.125" / 3.18mm), and flammability rating (UL94 V-0). The component is currently in active production status with confirmed inventory availability. ROHS3 compliance provides regulatory advantage over the obsolete original part.

319-10-164-00-001000 (Secondary Substitute)

This Mill-Max mating target connector operates at the same 0.100" (2.54mm) pitch and through-hole solder termination. However, it provides 64 contact positions rather than 20, making it suitable only for applications where the additional contact count does not create mechanical or electrical conflicts. Contact finish thickness on the mating surface (10.0µin / 0.25µm) is reduced compared to the original specification. This part is active production status with ROHS3 compliance and REACH Unaffected designation.

Both substitute parts carry MSL 1 (Unlimited) rating, REACH Unaffected status, and EAR99 ECCN classification, matching the regulatory profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can the 310-43-120-41-001000 be used as a direct replacement for the SIP1X20-041BLF?

A: Yes. Both components share identical mating pitch (0.100" / 2.54mm), position count (20), contact material (beryllium copper), contact finish specifications (gold mating at 30.0µin thickness, tin post at 200.0µin thickness), termination post length (0.125" / 3.18mm), and flammability rating (UL94 V-0). Through-hole solder termination and MSL 1 ratings are equivalent.

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

A: The 310-43-120-41-001000 maintains all original specifications including position count (20) and contact finish thicknesses. The 319-10-164-00-001000 provides 64 positions instead of 20 and features reduced mating contact finish thickness (10.0µin versus 30.0µin). Position count difference is the primary consideration for mechanical fit and circuit board layout compatibility.

Q: Are both substitute parts compliant with current regulatory requirements?

A: Yes. Both Mill-Max parts carry ROHS3 compliance and REACH Unaffected designation. The original SIP1X20-041BLF regulatory status was not specified for RoHS, making the substitute parts advantageous for new designs and ongoing support applications.

Q: What is the significance of the 0.100" (2.54mm) pitch specification?

A: This pitch is the standard spacing between contact positions. All three parts (original and both substitutes) maintain this identical pitch, ensuring compatibility with existing printed circuit board layouts, component footprints, and mating connectors designed for the SIP1X20-041BLF.

Q: Can the 319-10-164-00-001000 be used in applications requiring exactly 20 positions?

A: The 319-10-164-00-001000 provides 64 positions. Use in 20-position applications requires confirmation that the additional 44 positions do not create mechanical interference, electrical crosstalk, or circuit board layout conflicts. The 310-43-120-41-001000 is the recommended substitute for direct 20-position compatibility.

Q: What is the moisture sensitivity level (MSL) and why does it matter?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. All three parts carry this rating, meaning they can be stored and handled without special humidity control measures, simplifying inventory management and supply chain logistics.
