BS2I-IC BASIC Stamp® Embedded Module Equivalent & Substitute Parts

Part Overview

The BS2I-IC is a BASIC Stamp® Embedded Module featuring a PIC16C57C core processor operating at 20MHz with 2KB EEPROM and 32 bytes of RAM. This module is classified as an obsolete product, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs requiring equivalent performance characteristics.

The BS2I-IC represents a legacy embedded control solution within the BASIC Stamp® product family. Due to its obsolete status, locating direct replacements with identical electrical and mechanical specifications is essential for maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BS2I-IC is determined by strict equivalence across the following critical parameters:

Core Electrical Specifications:

• Identical core processor: PIC16C57C
• Matching operating frequency: 20MHz
• Equivalent memory configuration: 2KB EEPROM and 32 bytes RAM
• Same series family: BASIC Stamp®

Mechanical Compatibility:

• Identical physical dimensions: 1.200" L x 0.600" W (30.00mm x 15.00mm)
• Compatible module/board type: MCU Core

Functional Equivalence: Parts meeting all above criteria are classified as direct substitutes. The BS2-IC satisfies these requirements and is identified as the primary equivalent for the obsolete BS2I-IC.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: BS2-IC

The BS2-IC is the direct functional equivalent of the BS2I-IC. Both parts share identical core processor architecture, operating frequency, memory configuration, and physical dimensions, ensuring pin-for-pin and form-factor compatibility.

Product Status Consideration: The BS2I-IC is classified as obsolete, while the BS2-IC maintains active product status. Selection of the BS2-IC provides access to current manufacturing, quality assurance, and supply chain support from Parallax Inc.

Compliance and Environmental Factors: The BS2-IC carries RoHS Compliance certification and MSL Level 1 rating, indicating compliance with current environmental and moisture handling standards. The BS2I-IC predates these certifications and carries "Not applicable" status.

Operating Temperature Differential: The BS2I-IC specifies an operating range of -40°C to 85°C, while the BS2-IC operates within 0°C to 70°C. Applications requiring operation below 0°C or above 70°C must retain the BS2I-IC or evaluate alternative solutions outside this product family.

Frequently Asked Questions (FAQ)

Q: Is the BS2-IC a direct replacement for the BS2I-IC?

A: The BS2-IC is functionally equivalent to the BS2I-IC across all core electrical and mechanical parameters. Both utilize the PIC16C57C processor at 20MHz with 2KB EEPROM and 32 bytes RAM in identical physical packages. The BS2-IC is suitable for applications previously using the BS2I-IC, subject to operating temperature requirements.

Q: What is the primary difference between BS2I-IC and BS2-IC?

A: The BS2I-IC is obsolete, while the BS2-IC is an active product. The BS2-IC includes RoHS compliance and MSL Level 1 certification. The BS2I-IC supports extended temperature operation from -40°C, whereas the BS2-IC operates from 0°C to 70°C.

Q: Can I use BS2-IC in applications requiring -40°C operation?

A: No. The BS2-IC operating range begins at 0°C. Applications requiring operation below 0°C must use the BS2I-IC or identify alternative solutions outside the BASIC Stamp® family.

Q: Are there packaging differences between these parts?

A: The BS2I-IC packaging is listed as unspecified, while the BS2-IC is supplied in Bulk packaging. Both maintain identical physical dimensions of 1.200" L x 0.600" W (30.00mm x 15.00mm).

Q: What is the inventory status for these parts?

A: The BS2I-IC has 1107 pieces in stock as new original inventory. The BS2-IC has 1373 pieces in stock as new original inventory. Both are available for immediate procurement.

Q: Are both parts REACH compliant?

A: Yes. Both the BS2I-IC and BS2-IC carry REACH Unaffected status, indicating compliance with REACH regulations.
