Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP431ARG-7 is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt voltage reference architecture
• Output Type: Adjustable output voltage capability
• Voltage Range: 2.495V minimum to 36V maximum output
• Current Rating: 200 mA output current capacity
• Tolerance: ±0.5% accuracy specification
• Temperature Coefficient: 30 ppm/°C thermal stability
• Package: SC-59R (SOT-23-3) surface mount configuration
• Compliance: ROHS3 and REACH requirements

Only components matching all specified parameters across voltage range, current capacity, tolerance, and thermal characteristics qualify as direct substitutes. Package compatibility in SC-59R format is mandatory for mechanical and thermal performance equivalence.

Engineering Selection Recommendations

The AP431ARG-7 is classified as obsolete. Direct substitution with equivalent parts requires matching all electrical and mechanical specifications. The component maintains ROHS3 compliance and REACH unaffected status, supporting continued use in regulated applications.

Selection of substitute components must prioritize:

• Exact voltage output range (2.495V to 36V)
• Current capacity of 200 mA minimum
• Tolerance specification of ±0.5% or better
• SC-59R package format for PCB compatibility
• Maintained compliance certifications (ROHS3, REACH)
• Temperature coefficient performance within 30 ppm/°C specification

Inventory availability of 23,359 pieces in new original condition provides supply continuity for current production requirements.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the AP431ARG-7?

A: A valid substitute must match all critical parameters: shunt reference type, adjustable output capability, 2.495V to 36V voltage range, 200 mA output current, ±0.5% tolerance, 30 ppm/°C temperature coefficient, and SC-59R package format. Compliance certifications (ROHS3, REACH) must be maintained.

Q: Can I use a different package format as a substitute?

A: No. The SC-59R package is specified for this application. Different package formats alter thermal characteristics, PCB layout requirements, and mechanical fit. Package compatibility is mandatory for direct substitution.

Q: Why is the AP431ARG-7 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. However, inventory availability of 23,359 pieces supports continued supply for existing designs and production runs.

Q: What parameters are most critical for substitution compatibility?

A: The voltage output range (2.495V to 36V), current capacity (200 mA), tolerance (±0.5%), and package format (SC-59R) are the primary determinants of substitution compatibility. These parameters define the functional and mechanical equivalence required for direct replacement.

Q: Are there compliance considerations for substitute selection?

A: Yes. Substitute components must maintain ROHS3 compliance and REACH unaffected status to ensure regulatory compatibility with existing design certifications and production standards.
