SIP1X20-001BLF Equivalent & Substitute Parts

Part Overview

The SIP1X20-001BLF 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 components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SIP1X20-001BLF is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — establishes mechanical compatibility with standard 0.1-inch grid spacing
• Number of Positions: 20 positions — defines the contact count requirement
• Contact Finish - Mating: Gold — ensures electrical performance and corrosion resistance
• Mounting Type: Through Hole — specifies PCB assembly method
• Termination: Solder — defines connection to PCB
• Material Flammability Rating: UL94 V-0 — establishes safety compliance baseline

Two substitute components are identified:

1. 310-43-120-41-001000 (Mill-Max Manufacturing Corp.) — A 20-position receptacle connector that matches all critical mating parameters and maintains equivalent electrical and mechanical specifications.

2. 319-10-164-00-001000 (Mill-Max Manufacturing Corp.) — A 64-position spring mating target connector with 0.100" pitch and gold contact finish, suitable for applications requiring higher contact density while maintaining pitch compatibility.

Parameter Comparison

Engineering Selection Recommendations

310-43-120-41-001000 is the primary substitute for direct replacement applications. This component maintains identical position count (20), pitch (0.100"), contact finish (gold), and flammability rating (UL94 V-0) as the original SIP1X20-001BLF. Both components are rated for through-hole solder termination and unlimited moisture sensitivity. The substitute is currently in active production status with ROHS3 compliance, providing long-term availability and regulatory alignment.

319-10-164-00-001000 serves as an alternative for applications where increased contact density is acceptable. While this component maintains pitch compatibility and gold contact finish, it provides 64 positions rather than 20. This substitute is suitable only when the application can accommodate the higher contact count and does not require the UL94 V-0 flammability rating specification.

Frequently Asked Questions (FAQ)

Q: Can 310-43-120-41-001000 be used as a direct replacement for SIP1X20-001BLF?

A: Yes. Both components share identical critical parameters: 20 positions, 0.100" (2.54mm) pitch, gold mating contact finish, beryllium copper contact material, through-hole mounting, solder termination, and UL94 V-0 flammability rating. The substitute is currently in active production.

Q: What is the primary difference between the two substitute options?

A: The 310-43-120-41-001000 maintains the 20-position configuration of the original part. The 319-10-164-00-001000 provides 64 positions at the same 0.100" pitch. Selection depends on whether your application requires exactly 20 contacts or can utilize the higher contact density.

Q: Are both substitutes compatible with existing PCB layouts designed for SIP1X20-001BLF?

A: The 310-43-120-41-001000 is fully compatible with existing layouts due to identical position count and pitch. The 319-10-164-00-001000 requires PCB layout modification to accommodate 64 positions instead of 20.

Q: What compliance certifications apply to the substitute parts?

A: Both Mill-Max substitutes are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1). The 310-43-120-41-001000 maintains the UL94 V-0 flammability rating of the original component. The 319-10-164-00-001000 does not specify a flammability rating.

Q: Are the substitute parts available in the same packaging as the original?

A: The 310-43-120-41-001000 is supplied in bulk packaging. The 319-10-164-00-001000 is supplied in tube packaging. Original packaging specifications for SIP1X20-001BLF were not provided in the component data.
