AP7361C-18SPR-13 Equivalent & Substitute Parts

Part Overview

The AP7361C-18SPR-13 is a linear voltage regulator IC from Diodes Incorporated, classified as a Power Management (PMIC) component. This device delivers a fixed 1.8V output at 1A maximum current with integrated over-current and over-temperature protection. The part is actively manufactured and maintains full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when electrical specifications, output configuration, and mechanical packaging remain identical across the product line.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AP7361C-18SPR-13 are identified based on strict parametric equivalence. The substitution criteria include:

• Fixed output voltage of 1.8V
• Maximum output current of 1A
• Maximum input voltage of 6V
• Dropout voltage of 0.57V @ 1A (Typical)
• Quiescent current of 80 µA
• PSRR specification of 75dB ~ 55dB (1kHz ~ 10kHz)
• Operating temperature range of -40°C ~ 85°C
• 8-SOIC package with exposed pad (0.154", 3.90mm Width)
• Surface mount configuration
• Over-current and over-temperature protection
• Enable control feature
• Active product status
• RoHS3 compliance

The AP7361C-18SP-13 meets all these criteria and is classified as a parametric equivalent. The difference between the main part and substitute lies in the packaging designation suffix (SPR-13 versus SP-13), which reflects different tape and reel configurations from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

Both the AP7361C-18SPR-13 and AP7361C-18SP-13 are active products from Diodes Incorporated with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than functional performance. Both parts maintain full RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The MSL 1 rating (unlimited moisture sensitivity) indicates no special storage or handling precautions are required. Component selection should be based on tape and reel configuration availability and procurement lead times.

Frequently Asked Questions (FAQ)

Q: Can AP7361C-18SP-13 be used as a direct replacement for AP7361C-18SPR-13?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage, current rating, dropout voltage, protection features, and 8-SOIC package configuration. The suffix difference (SPR-13 versus SP-13) indicates different tape and reel packaging formats from the same manufacturer.

Q: What is the difference between the SPR-13 and SP-13 suffixes?

A: The suffix designates the tape and reel configuration used for automated assembly. Both configurations contain the same die and package. Selection depends on your assembly equipment compatibility and supplier availability.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts share identical thermal characteristics, quiescent current, PSRR performance, and operating temperature range (-40°C ~ 85°C).

Q: Do both parts require the same PCB footprint?

A: Yes. Both parts use the 8-SOIC (0.154", 3.90mm Width) package with exposed pad. PCB layout and thermal management considerations are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating.

Q: What inventory considerations should I account for?

A: AP7361C-18SPR-13 has 2620 pcs in stock, while AP7361C-18SP-13 has 1539 pcs in stock. Availability may influence selection based on project timeline and volume requirements.
