Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS62040DRCRG4 is determined by strict alignment with the following electrical and mechanical parameters:

• Input voltage range: 2.5V to 6V
• Output voltage adjustability: 0.7V to 6V
• Output current capability: 1.2A
• Switching frequency: 1.25MHz
• Synchronous rectifier presence: Yes
• Package type: 10-VFDFN Exposed Pad (10-VSON 3x3)
• Mounting type: Surface Mount
• Operating temperature range: -40°C to 85°C
• RoHS3 compliance
• MSL rating: 2 (1 Year)

The TPS62040DRCR meets all these criteria and qualifies as a direct substitute. The primary difference is packaging format: the main part uses DiGi Electronics tube packaging, while the substitute uses Tape & Reel (TR) packaging. Both parts share identical electrical specifications and the same base product number (TPS62040).

Parameter Comparison

Engineering Selection Recommendations

The TPS62040DRCR is a qualified substitute for the TPS62040DRCRG4 based on electrical and mechanical parameter equivalence. Both parts are manufactured by Texas Instruments, share identical functional specifications, and maintain ROHS3 compliance with matching MSL ratings.

The TPS62040DRCR holds active product status, ensuring ongoing availability and supply chain reliability. The packaging difference (Tape & Reel versus tube) does not affect electrical performance or PCB-level compatibility. Selection between these parts should be based on procurement requirements, quantity needs, and supply chain logistics rather than technical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can the TPS62040DRCR be used as a direct replacement for the TPS62040DRCRG4?

A: Yes. Both parts are electrically and mechanically identical. They share the same input/output voltage ranges, current rating, switching frequency, package type, and operating temperature specifications. The only difference is the packaging format (Tape & Reel versus tube).

Q: What is the significance of the packaging format difference?

A: Packaging format affects handling, storage, and automated assembly processes. Tape & Reel (TR) packaging is optimized for high-volume automated pick-and-place assembly, while tube packaging is suitable for lower-volume or manual assembly. The actual component and its electrical performance remain unchanged.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, MSL ratings, and regulatory certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001).

Q: Why is the TPS62040DRCRG4 discontinued?

A: The main part is discontinued at DiGi Electronics. The TPS62040DRCR remains active and available, providing continuity for designs requiring this buck regulator topology and specifications.

Q: Are there any design considerations when switching between these part numbers?

A: No design changes are required. PCB layout, schematic connections, and external component values remain identical. The substitution is transparent at the circuit level.
