S-1000C31-I4T1U Equivalent & Substitute Parts

Part Overview

The S-1000C31-I4T1U is a voltage supervisor IC manufactured by ABLIC Inc., classified as a Power Management (PMIC) component. This single-channel voltage detector operates with a 3.1V threshold and provides push-pull, totem pole output with active low reset functionality. The device is housed in a 4-SMD flat lead package (SNT-4A) and is suitable for surface mount applications across industrial and commercial temperature ranges (-40°C to 85°C). As an active product with full RoHS3 compliance and unlimited moisture sensitivity rating, substitute parts may be required due to packaging format availability, inventory constraints, or specific application requirements for alternative tape configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S-1000C31-I4T1U is determined by strict equivalence across the following critical parameters:

• Voltage threshold: 3.1V
• Output type: Push-Pull, Totem Pole
• Reset polarity: Active Low
• Number of monitored channels: 1
• Package type: 4-SMD, Flat Leads (SNT-4A)
• Operating temperature range: -40°C ~ 85°C
• Mounting technology: Surface Mount

The S-1009C31I-I4T1U qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications, threshold voltage, output configuration, and thermal operating range. The primary distinction is the packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is available in Cut Tape (CT) format. Both formats contain the same component in the same physical package and are suitable for equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the S-1000C31-I4T1U and S-1009C31I-I4T1U are active products with full regulatory compliance (RoHS3 and REACH unaffected status). Selection between these parts should be based on packaging and supply chain requirements:

The S-1000C31-I4T1U in Tape & Reel format is suitable for high-volume automated assembly operations where continuous tape feeding is required. The S-1009C31I-I4T1U in Cut Tape format is appropriate for lower-volume applications, manual assembly processes, or situations where individual component handling is preferred. Both parts deliver identical electrical performance and thermal characteristics within the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can S-1009C31I-I4T1U replace S-1000C31-I4T1U in my circuit?

A: Yes. Both parts are parametric equivalents with identical voltage threshold (3.1V), output configuration (push-pull, totem pole), reset polarity (active low), and operating temperature range (-40°C to 85°C). The only difference is packaging format (Cut Tape versus Tape & Reel).

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) supplies components on continuous tape wound on a reel, suitable for automated pick-and-place assembly. Cut Tape (CT) provides the same components on tape segments, typically used for manual assembly or lower-volume production. The physical component and electrical performance are identical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both S-1000C31-I4T1U and S-1009C31I-I4T1U meet RoHS3 compliance requirements and are REACH unaffected.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I use these parts interchangeably in my PCB design?

A: Yes. Both parts use the identical SNT-4A package (4-SMD, flat leads) with the same pinout and electrical specifications. No circuit modifications are required for substitution.
