Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS1851ID is determined by compatibility across the following critical parameters:

Mechanical Compatibility:

• Package type: 8-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Pin count and footprint alignment

Electrical Compatibility:

• Output type: Rail-to-Rail
• Number of circuits: 1
• Voltage supply range: Minimum 1.8 V, Maximum 6 V (substitute must support the full operating range)
• Operating temperature range: -40°C ~ 125°C

Regulatory & Compliance:

• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts identified (MCP6N11-010E/SN and MCP6N11T-001E/SN) satisfy all mechanical and electrical compatibility requirements. Both are manufactured by Microchip Technology and maintain active product status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TS1851ID is classified as obsolete. Both substitute parts (MCP6N11-010E/SN and MCP6N11T-001E/SN) maintain active product status with Microchip Technology, ensuring continued availability, technical support, and manufacturing consistency.

Compliance & Certification: All three components are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. Both substitute parts maintain identical compliance certifications, supporting seamless integration into regulated manufacturing environments.

Supply Chain Continuity: MCP6N11-010E/SN is available in tube packaging with 10,100 pieces in stock. MCP6N11T-001E/SN is available in tape and reel packaging with 765 pieces in stock. Active product status guarantees long-term procurement viability for both alternatives.

Packaging & Mechanical Compatibility: Both substitute parts utilize the identical 8-SOIC (0.154", 3.90mm Width) package with surface mount configuration. Direct footprint compatibility is confirmed, eliminating PCB redesign requirements.

Electrical Operating Range: Both substitute parts operate across the 1.8 V minimum supply voltage required by the TS1851ID. The maximum supply voltage for substitutes is 5.5 V, which accommodates applications operating within this range. Applications requiring the full 6 V maximum of the TS1851ID require circuit-level evaluation.

Frequently Asked Questions (FAQ)

Q: Can MCP6N11-010E/SN and MCP6N11T-001E/SN be used interchangeably with TS1851ID?

A: Both parts are mechanically and electrically compatible with the TS1851ID in terms of package footprint, pin configuration, and core operating parameters. The primary difference is packaging format: MCP6N11-010E/SN is supplied in tube packaging, while MCP6N11T-001E/SN is supplied in tape and reel format. Selection depends on assembly process requirements.

Q: What is the difference between MCP6N11-010E/SN and MCP6N11T-001E/SN?

A: Both parts share identical electrical specifications and the same 8-SOIC package. The designation suffix indicates packaging format: "-010E/SN" denotes tube packaging, while "T-001E/SN" denotes tape and reel packaging. Electrical performance and pin compatibility are identical.

Q: Are there supply voltage limitations when substituting?

A: The TS1851ID supports 1.8 V to 6 V supply operation. Both substitute parts support 1.8 V to 5.5 V. Applications operating at 5.5 V or below are fully compatible. Circuits requiring 6 V operation require evaluation of alternative components or circuit modification.

Q: Do the substitute parts require PCB layout changes?

A: No. Both MCP6N11-010E/SN and MCP6N11T-001E/SN utilize the identical 8-SOIC (0.154", 3.90mm Width) package with surface mount configuration. Direct footprint compatibility is confirmed without PCB redesign.

Q: What is the difference between general-purpose and instrumentation amplifier types?

A: The TS1851ID is classified as a general-purpose amplifier, while both substitute parts are instrumentation amplifiers. Instrumentation amplifiers provide higher input impedance and lower input bias current (10 pA versus 16 nA), making them suitable for precision measurement applications. Both device types are rail-to-rail output operational amplifiers compatible with the TS1851ID pinout.

Q: Are compliance certifications maintained with substitution?

A: Yes. All three components are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity ratings. Regulatory compliance is maintained across substitution.

Q: What is the inventory status for each substitute part?

A: MCP6N11-010E/SN has 10,100 pieces in stock (tube packaging). MCP6N11T-001E/SN has 765 pieces in stock (tape and reel packaging). Both parts maintain active product status, ensuring continued availability.
