Key Parameters

Substitute Part Grouping Explanation

Substitution for the AP1702FWG-7 is determined by strict equivalence across the following critical parameters:

Core Functional Parameters:

• Voltage threshold: 2.63V
• Output configuration: Push-Pull, Totem Pole
• Reset logic: Active High
• Number of voltages monitored: 1 channel
• Supervisor type: Simple Reset/Power-On Reset

Mechanical Compatibility:

• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting type: Surface Mount

Compliance & Environmental:

• RoHS3 Compliant
• REACH Unaffected
• EAR99 classification

Substitute parts are grouped into two categories based on availability and product lifecycle status:

Direct Substitutes (Active Status): Parts with identical functional parameters and active product status, offering long-term availability and support.

Parametric Equivalents (Obsolete Status): Parts with matching core parameters but obsolete status, suitable for legacy system maintenance.

Engineering Selection Recommendations

For Active System Designs: Select from parts with Active product status: APX810-26SAG-7, ADM810RARTZ-REEL7, TCM810RENB713, or TCM810RVNB713. These parts ensure long-term availability, manufacturer support, and compliance with current RoHS3 and REACH standards.

For Extended Temperature Range Requirements: ADM810RARTZ-REEL7 and TCM810RVNB713 support operating temperatures to 125°C, exceeding the original AP1702FWG-7 specification of 70°C maximum. These are suitable for applications requiring enhanced thermal performance.

For Legacy System Maintenance: AP1704FWG-7 provides parametric equivalence with identical operating temperature range and reset timeout specifications. This part maintains compatibility with existing SC-59-3 package designs.

Package Considerations: The original AP1702FWG-7 uses SC-59-3 packaging. Most active substitutes transition to SOT-23-3 packaging, which is mechanically and electrically compatible within the TO-236-3 family. Verify PCB layout compatibility before implementation.

Compliance Verification: All listed substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can APX810-26SAG-7 directly replace AP1702FWG-7 in existing designs? A: APX810-26SAG-7 maintains identical voltage threshold (2.63V), output configuration (push-pull, totem pole), and reset logic (active high). The reset timeout increases from 100ms to 140ms minimum, and operating temperature range expands to -40°C ~ 85°C. PCB layout must accommodate SOT-23-3 packaging instead of SC-59-3. Functional compatibility is confirmed; physical layout verification is required.

Q: What is the difference between TCM810RENB713 and TCM810RVNB713? A: Both parts are manufactured by Microchip Technology with identical functional parameters (2.63V threshold, push-pull output, active high reset, 140ms timeout). TCM810RENB713 operates at -40°C ~ 85°C and is supplied in tape & reel packaging. TCM810RVNB713 extends the operating range to -40°C ~ 125°C and is supplied in cut tape packaging. Select based on temperature requirements and packaging preference.

Q: Why does AP1702FWG-7 show as obsolete? A: AP1702FWG-7 is classified as obsolete by the manufacturer, indicating end-of-life status and discontinued production. Active substitutes with equivalent functionality are available from multiple manufacturers to support ongoing applications.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the environmental and regulatory requirements of the original AP1702FWG-7.

Q: What is the significance of MSL (Moisture Sensitivity Level) differences? A: The original AP1702FWG-7 has MSL 3 (168 hours), requiring controlled storage conditions. Active substitutes have MSL 1 (unlimited), indicating superior moisture resistance and simplified handling requirements. This represents an improvement in manufacturing and storage flexibility.

Q: Can I use ADM810RARTZ-REEL7 in applications requiring 0°C minimum operating temperature? A: ADM810RARTZ-REEL7 operates at -40°C minimum, which exceeds the 0°C requirement of AP1702FWG-7. This part is suitable for applications with 0°C minimum specifications and provides additional thermal margin for lower temperature environments.
