Parameter Comparison

Engineering Selection Recommendations

Both ZXTR2108F-7 and ZXTR2108FQ-7 are active products from Diodes Incorporated with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements:

ZXTR2108F-7 is suitable for applications requiring bulk packaging formats, typically for lower-volume production runs or prototype development.

ZXTR2108FQ-7 is specified for automated assembly processes utilizing tape and reel packaging, standard for high-volume manufacturing environments.

Both parts maintain full automotive qualification under AEC-Q101 and comply with ROHS3 requirements. The MSL 1 rating indicates unlimited shelf life under standard storage conditions. Direct substitution is valid in any application where the ZXTR2108F-7 is currently specified, provided the receiving assembly process accommodates the packaging format.

Frequently Asked Questions (FAQ)

Q: Can ZXTR2108FQ-7 replace ZXTR2108F-7 in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus bulk). Substitution is valid if your assembly equipment supports tape and reel input.

Q: Are there any electrical performance differences between these parts?

A: No. Output voltage, current rating, input voltage range, quiescent current, PSRR, and operating temperature specifications are identical across both part numbers.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both ZXTR2108F-7 and ZXTR2108FQ-7 are AEC-Q101 qualified and automotive grade, suitable for automotive applications.

Q: What is the significance of the packaging difference?

A: ZXTR2108F-7 uses bulk packaging for manual handling or lower-volume applications. ZXTR2108FQ-7 uses tape and reel packaging for automated pick-and-place assembly in high-volume production. The electrical performance is identical.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection under standard storage conditions.

Q: Can I use these parts interchangeably in the same circuit design?

A: Yes. The SOT-23-3 package pinout and electrical specifications are identical, allowing direct substitution in any circuit application where the ZXTR2108F-7 is specified.
