SIP1X03-011BLF Equivalent & Substitute Parts

Part Overview

The SIP1X03-011BLF is a 3-position SIP socket manufactured by Amphenol ICC (FCI), designed for through-hole mounting applications. This component features gold-plated beryllium copper mating contacts and tin-plated brass posts, providing reliable electrical connectivity in single in-line package configurations. The part is classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure ongoing component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SIP1X03-011BLF is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — establishes mechanical and electrical spacing compatibility
• Number of Positions: 3 positions — defines connector capacity and footprint
• Contact Finish - Mating: Gold — ensures equivalent electrical performance and corrosion resistance
• Mounting Type: Through Hole — maintains PCB assembly compatibility
• Termination: Solder — preserves board-level integration method
• Material Flammability Rating: UL94 V-0 — maintains safety compliance requirements
• Moisture Sensitivity Level: 1 (Unlimited) — ensures storage and handling compatibility

The identified substitute parts meet these core parameters while offering active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

310-43-103-41-001000 is the primary substitute for SIP1X03-011BLF. This component maintains all critical electrical and mechanical parameters: 3-position configuration, 0.100" (2.54mm) pitch, gold-plated beryllium copper mating contacts, tin-plated brass posts, 0.125" (3.18mm) termination post length, UL94 V-0 flammability rating, and MSL 1 classification. The part is currently active in production with confirmed inventory availability. ROHS3 compliance provides additional regulatory alignment for modern manufacturing environments.

319-10-164-00-001000 is not recommended as a direct substitute. While this component shares the 0.100" (2.54mm) pitch, gold contact finish, and through-hole mounting characteristics, it is a 64-position spring mating target connector with fundamentally different form factor, contact material (brass alloy rather than beryllium copper), and functional purpose. This part does not satisfy the 3-position requirement and represents a different connector category.

Frequently Asked Questions (FAQ)

Q: Can 310-43-103-41-001000 be used as a direct replacement for SIP1X03-011BLF?

A: Yes. The 310-43-103-41-001000 maintains identical pitch (0.100" / 2.54mm), position count (3), contact finish (gold), post length (0.125" / 3.18mm), and flammability rating (UL94 V-0). Both components are through-hole solder-terminated connectors with equivalent electrical and mechanical specifications.

Q: Why is 319-10-164-00-001000 listed as a substitute if it has 64 positions?

A: The 319-10-164-00-001000 was included in the original substitute list but does not meet substitution criteria. The 64-position configuration and mating target connector type are incompatible with the 3-position SIP socket requirement. This part should not be selected for replacement applications.

Q: What are the key compatibility factors when selecting a substitute?

A: Substitution compatibility is determined by: pitch spacing (0.100" / 2.54mm), position count (3), mating contact finish (gold), mounting method (through-hole), termination type (solder), post length (0.125" / 3.18mm), and flammability compliance (UL94 V-0). All these parameters must align with the original design specification.

Q: Is the 310-43-103-41-001000 available in the same packaging as the original part?

A: The 310-43-103-41-001000 is supplied in bulk packaging, whereas the original SIP1X03-011BLF packaging specification was not provided. Verify packaging requirements with your procurement process to ensure compatibility with assembly operations.

Q: Are there any compliance differences between the main part and the recommended substitute?

A: The 310-43-103-41-001000 carries ROHS3 compliance certification, which the original part specification did not indicate. Both components maintain MSL 1 (Unlimited) moisture sensitivity classification and equivalent electrical safety ratings.
