Substitute Part Grouping Explanation

Substitution eligibility for the MP2018GZD-5-Z is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Output voltage configuration: Positive fixed 5V
• Output current rating: 500mA
• Input voltage maximum: 16V
• Voltage dropout specification: 1V @ 500mA
• Quiescent current: 17 µA
• PSRR performance: 57dB ~ 51dB (100Hz ~ 100kHz)
• Protection features: Over Current, Over Temperature, Short Circuit
• Control features: Power Good

Mechanical & Compliance Equivalence Criteria:

• Package type: TO-252-5 (DPAK, 5 Leads + Tab)
• Mounting type: Surface Mount
• Operating temperature range: -40°C to 125°C
• RoHS3 compliance
• MSL rating: 3 (168 Hours)
• REACH status: REACH Unaffected

The identified substitute part maintains identical electrical specifications and compliance certifications. The only permitted variation is in packaging format (Tape & Reel versus Cut Tape), which does not affect component functionality or performance.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The MP2018GZD-5-Z and MP2018GZD-5-P are functionally equivalent linear voltage regulators with identical electrical performance specifications. Both parts are manufactured by Monolithic Power Systems Inc., maintain active product status, and carry ROHS3 compliance certification.

Packaging Format Consideration:

The sole distinction between these parts is the distribution packaging format. The MP2018GZD-5-Z is supplied in Tape & Reel (TR) format, suitable for high-volume automated assembly operations. The MP2018GZD-5-P is supplied in Cut Tape (CT) format, appropriate for lower-volume applications or manual assembly processes.

Compliance & Certification:

Both parts satisfy identical regulatory requirements: ROHS3 compliance, REACH unaffected status, MSL rating 3 (168 Hours), and ECCN EAR99 classification. No compliance differential exists between the two part numbers.

Inventory & Availability:

Selection between these substitutes may be influenced by current inventory levels and procurement lead times. The MP2018GZD-5-P currently maintains higher inventory availability (1450 units) compared to the MP2018GZD-5-Z (922 units).

Frequently Asked Questions (FAQ)

Q: Are MP2018GZD-5-Z and MP2018GZD-5-P electrically interchangeable?

A: Yes. Both parts deliver identical electrical performance: 5V fixed output, 500mA output current, 1V maximum dropout at rated current, 17 µA quiescent current, and equivalent protection features (Over Current, Over Temperature, Short Circuit). They operate across the same temperature range (-40°C to 125°C) and maintain identical PSRR specifications.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly at high production volumes. Cut Tape (CT) packaging supplies the same components on shorter tape segments, suitable for lower-volume manual or semi-automated assembly. The component itself is identical; only the distribution format differs.

Q: Can I use MP2018GZD-5-P as a direct replacement for MP2018GZD-5-Z in my design?

A: Yes. Both parts are pin-compatible, package-compatible (TO-252-5 DPAK), and electrically equivalent. No circuit modifications or PCB layout changes are required. The substitution is valid for any application currently using MP2018GZD-5-Z.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MP2018GZD-5-Z and MP2018GZD-5-P are ROHS3 compliant, REACH unaffected, carry MSL rating 3 (168 Hours), and share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: Which part should I select for my application?

A: Selection depends on your assembly process and procurement requirements. Choose MP2018GZD-5-Z (Tape & Reel) for high-volume automated assembly. Choose MP2018GZD-5-P (Cut Tape) for lower-volume production or when Cut Tape format aligns with your supply chain logistics. Both deliver identical performance.

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

A: No. Both parts maintain identical thermal specifications, quiescent current (17 µA), supply current maximum (150 µA), and PSRR performance across the 100Hz to 100kHz frequency range. Thermal performance and power dissipation characteristics are equivalent.
