Substitute Part Grouping Explanation

Substitution of the AP7315D-28W5-7 is determined by strict equivalence across the following critical parameters:

Output voltage specification: 2.8V fixed
Maximum output current: 150mA
Maximum input voltage: 5.25V
Maximum dropout voltage: 0.29V @ 150mA
Package type: SOT-25 (SC-74A, SOT-753)
Surface Mount configuration
Operating temperature range: -40°C ~ 85°C
Control features: Enable function
Protection features: Over Current protection
Compliance: ROHS3 Compliant

The AP7315-28W5-7 meets all these criteria and is classified as a parametric equivalent. The primary distinction between the main part and substitute is packaging format: the main part is supplied in standard packaging, while the substitute is available in Tape & Reel (TR) format.

Engineering Selection Recommendations

Both the AP7315D-28W5-7 and AP7315-28W5-7 are Active product status components manufactured by Diodes Incorporated. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Selection between these parts should be based on procurement requirements and assembly processes. The main part (AP7315D-28W5-7) is available in standard packaging, while the substitute (AP7315-28W5-7) is supplied in Tape & Reel format. Tape & Reel packaging is optimized for automated pick-and-place assembly operations and high-volume production environments. Standard packaging may be preferred for lower-volume applications or manual assembly processes.

All electrical specifications, thermal characteristics, and functional performance are identical between the two parts. PCB layout, schematic design, and circuit functionality require no modification when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can AP7315-28W5-7 be used as a direct replacement for AP7315D-28W5-7?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Tape & Reel versus standard packaging. No circuit modifications are required.

Q: What is the difference between standard packaging and Tape & Reel (TR) format?

A: Tape & Reel format supplies components wound on continuous tape within a reel, designed for automated assembly equipment. Standard packaging typically refers to bulk or alternative packaging formats. Both formats contain identical components with identical specifications.

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

A: No. Both parts have identical operating temperature ranges (-40°C ~ 85°C), dropout voltage specifications (0.29V @ 150mA), output current ratings (150mA), and all other electrical parameters.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings (1 - Unlimited). No compliance differences exist between the two parts.

Q: Which part should be selected for high-volume production?

A: The AP7315-28W5-7 in Tape & Reel format is optimized for high-volume automated assembly. Standard packaging may be more suitable for lower-volume or manual assembly applications.

Q: Is PCB layout modification required when switching between these parts?

A: No. Both parts use identical SOT-25 (SC-74A, SOT-753) packaging. PCB footprints, pin assignments, and layout requirements are identical.
