AS1907C16-T Equivalent & Substitute Parts

Part Overview

The AS1907C16-T is a single-channel power management supervisor IC manufactured by ams-OSRAM USA INC. in SOT-23-3 surface mount packaging. This device functions as a simple reset/power-on reset supervisor with push-pull totem pole output configuration and active low reset logic. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The AS1907C16-T operates across the industrial temperature range of -40°C to 125°C and monitors a single supply voltage with a 1.6V threshold setting.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AS1907C16-T is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Single voltage monitoring channel
• 1.6V threshold voltage setting
• Push-pull totem pole output stage
• Active low reset logic
• 100ms minimum reset timeout
• Operating temperature range: -40°C to 125°C

Mechanical & Packaging Equivalence Criteria:

• Surface mount technology
• SOT-23-3 package / TO-236-3 case
• Moisture sensitivity level 1 (unlimited)

Compliance & Regulatory Equivalence:

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

The MAX6333UR16D3+T from Analog Devices Inc./Maxim Integrated meets all specified electrical, mechanical, and regulatory parameters and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The MAX6333UR16D3+T is a direct parametric equivalent to the AS1907C16-T across all specified electrical, mechanical, and regulatory parameters. The substitute part maintains identical functional characteristics: single-channel voltage monitoring at 1.6V threshold, push-pull totem pole output, active low reset logic, and 100ms minimum reset timeout. Both parts operate across the full industrial temperature range of -40°C to 125°C and utilize identical SOT-23-3 surface mount packaging.

A key distinction is product status: the AS1907C16-T is obsolete, while the MAX6333UR16D3+T is active. The MAX6333UR16D3+T additionally carries ROHS3 compliance certification, providing enhanced environmental and regulatory alignment for new designs and long-term supply chain stability. Both parts maintain REACH unaffected status and EAR99 ECCN classification, ensuring consistent export and regulatory compliance.

Selection of the MAX6333UR16D3+T is supported by its active product status, ongoing manufacturer support, and verified compliance certifications. The part is available in Tape & Reel packaging format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the MAX6333UR16D3+T directly replace the AS1907C16-T in existing designs?

A: Yes. The MAX6333UR16D3+T is a parametric equivalent across all specified electrical and mechanical parameters. Both parts feature identical voltage threshold (1.6V), output configuration (push-pull totem pole), reset logic (active low), reset timeout (100ms minimum), operating temperature range (-40°C to 125°C), and SOT-23-3 packaging. No circuit modifications are required for direct substitution.

Q: What is the significance of the AS1907C16-T being obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by ams-OSRAM USA INC. The MAX6333UR16D3+T, classified as active, is currently manufactured and supported by Analog Devices Inc./Maxim Integrated, ensuring ongoing availability and technical support for new designs and production continuity.

Q: Are there packaging differences between these parts?

A: Both parts use identical SOT-23-3 surface mount packaging (TO-236-3, SC-59). The AS1907C16-T packaging format is not specified in available data. The MAX6333UR16D3+T is supplied in Tape & Reel format, which is standard for automated assembly operations. Both parts maintain MSL 1 (unlimited) moisture sensitivity rating.

Q: What compliance certifications apply to the substitute part?

A: The MAX6333UR16D3+T carries ROHS3 compliance certification in addition to REACH unaffected status and EAR99 ECCN classification, which are shared with the AS1907C16-T. ROHS3 compliance ensures the part meets current environmental and hazardous substance restrictions.

Q: Are there inventory considerations for these parts?

A: The AS1907C16-T has 3590 pieces available as new original stock. The MAX6333UR16D3+T has 2700 pieces available as new original stock. Both parts are available for immediate procurement.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution is determined by equivalence in: single voltage monitoring channel, 1.6V threshold voltage, push-pull totem pole output stage, active low reset logic, and 100ms minimum reset timeout. All these parameters are identical between the AS1907C16-T and MAX6333UR16D3+T.
