AS1917S-T-Z Equivalent & Substitute Parts

Part Overview

The AS1917S-T-Z is a single-channel power management integrated circuit (PMIC) supervisor manufactured by ams-OSRAM USA INC. in SOT-23-5 surface mount packaging. This device functions as a simple reset/power-on reset controller with push-pull totem pole output configuration, designed to monitor a single voltage threshold at 2.93V with an active high reset signal and 100ms minimum reset timeout.

The AS1917S-T-Z carries an obsolete product status. Identification of equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this supervisor topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AS1917S-T-Z is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Single voltage monitoring channel
• 2.93V threshold voltage
• Push-pull totem pole output stage
• Active high reset logic
• 100ms minimum reset timeout duration

Physical & Environmental Parameters:

• SOT-23-5 package (SC-74A, SOT-753 case designation)
• Surface mount technology
• Operating temperature range: -40°C to 125°C
• Moisture sensitivity level 1 (unlimited)

Regulatory & Compliance Parameters:

• REACH unaffected status
• ECCN classification: EAR99
• HTSUS code: 8542.39.0001

The AS1917-T-Z qualifies as a parametric equivalent substitute based on identical functional specifications, package configuration, and environmental operating parameters. Packaging format differences (Cut Tape versus other formats) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AS1917-T-Z is the direct parametric equivalent substitute for the AS1917S-T-Z. All critical electrical, mechanical, and environmental specifications are identical across both parts.

Primary Selection Advantage: The AS1917-T-Z carries active product status, ensuring ongoing availability and supply chain continuity. The main part AS1917S-T-Z is classified as obsolete, creating long-term sourcing risk.

Compliance Advantage: The AS1917-T-Z is explicitly certified as RoHS Compliant, providing enhanced regulatory alignment for new designs and manufacturing environments subject to RoHS requirements. Both parts maintain REACH unaffected status and identical ECCN/HTSUS classifications.

Packaging Consideration: The AS1917-T-Z is supplied in Cut Tape (CT) format. This packaging format does not alter electrical performance or mechanical compatibility with the original SOT-23-5 footprint. Design implementation remains unchanged.

Inventory Status: Current inventory of AS1917-T-Z (1091 Pcs) exceeds that of AS1917S-T-Z (1088 Pcs), supporting immediate procurement without lead time constraints.

Frequently Asked Questions (FAQ)

Q: Are the AS1917S-T-Z and AS1917-T-Z electrically identical?

A: Yes. Both parts share identical voltage threshold (2.93V), output configuration (push-pull totem pole), reset logic (active high), reset timeout (100ms minimum), and operating temperature range (-40°C to 125°C). No circuit redesign is required for substitution.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. The AS1917S-T-Z is obsolete; the AS1917-T-Z is active. The AS1917-T-Z also carries explicit RoHS Compliance certification. Both parts use identical SOT-23-5 packaging and share the same base product number (AS1917).

Q: Can I use AS1917-T-Z in place of AS1917S-T-Z on existing PCBs?

A: Yes. The SOT-23-5 footprint (SC-74A, SOT-753 case) is identical for both parts. No PCB layout modifications are necessary. Pin configuration, electrical performance, and thermal characteristics are equivalent.

Q: Does the Cut Tape packaging format affect compatibility?

A: No. Cut Tape (CT) is a supply format only. It does not alter the component's electrical specifications, mechanical dimensions, or performance characteristics. The part itself is identical to other packaging formats of the same device.

Q: Is the AS1917-T-Z RoHS compliant?

A: Yes. The AS1917-T-Z is explicitly certified as RoHS Compliant. The AS1917S-T-Z RoHS status is not specified in available documentation.

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

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special desiccant or humidity control requirements.

Q: Are there any other substitute options for the AS1917S-T-Z?

A: Based on the provided parametric data, the AS1917-T-Z is the documented equivalent substitute. No additional alternatives are specified in the substitute parts list.
