REF5050MDREP Equivalent & Substitute Parts

Part Overview

The REF5050MDREP is a series voltage reference IC manufactured by Texas Instruments, delivering a fixed 5V output with ±0.05% tolerance. Classified as a Power Management (PMIC) component, this 8-SOIC surface mount device operates across the industrial temperature range of -55°C to 125°C and is ROHS3 compliant. The part is currently active in production with 3213 units in stock. Equivalent and substitute parts are identified when design requirements permit relaxation of tolerance, temperature coefficient, noise performance, or input voltage range specifications while maintaining the core 5V fixed output, 10mA output current, and 8-SOIC package compatibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters: fixed 5V output voltage, 10mA output current capability, 8-SOIC package format, surface mount technology, and ROHS3 compliance. Substitute parts are grouped into three categories based on tolerance performance:

Tolerance ±0.1% Group: ADR02ARZ-REEL, ADR02ARZ-REEL7, and ADR02WARZ-REEL7 maintain the same output current and package but accept wider tolerance. These parts feature improved input voltage range (7V ~ 36V for ADR02ARZ variants, 7V ~ 26V for ADR02WARZ-REEL7) and lower supply current (1mA). Operating temperature range is -40°C ~ 125°C.

Tolerance ±0.06% Group: ADR02BRZ and ADR02BRZ-REEL7 provide tighter tolerance than the ±0.1% group with superior temperature coefficient (3ppm/°C). Input voltage range extends to 7V ~ 36V with 1mA supply current and -40°C ~ 125°C operating temperature.

Tolerance ±0.04% Group: MAX875AESA+ delivers the tightest tolerance specification with enhanced noise performance (9µVp-p at 0.1Hz to 10Hz, 14.5µVrms at 10Hz to 10kHz). Input voltage range is 7V ~ 18V with 700µA supply current. Operating temperature is limited to -40°C ~ 85°C.

Tolerance ±0.06% MAX875 Group: MAX875BESA+ and MAX875BESA+T provide ±0.06% tolerance with identical noise and supply current characteristics to MAX875AESA+, operating within -40°C ~ 85°C range.

Tolerance ±0.5% and ±1% Group: REF02HSZ and REF02CSZ represent lower-precision alternatives with significantly relaxed tolerance specifications, suitable for applications where voltage reference accuracy is non-critical. Input voltage range is 8V ~ 36V with operating temperature -40°C ~ 85°C.

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and active product status. Selection between substitute options depends on application-specific tolerance and temperature requirements.

For applications requiring the REF5050MDREP's extended operating temperature range (-55°C ~ 125°C), no direct substitute exists among the listed alternatives. The ADR02ARZ-REEL, ADR02ARZ-REEL7, ADR02BRZ, and ADR02BRZ-REEL7 extend the upper temperature limit to 125°C while maintaining -40°C minimum, making them suitable for industrial applications that do not require the -55°C lower bound.

For applications operating within -40°C ~ 85°C, the MAX875AESA+ offers the tightest tolerance specification (±0.04%) with the lowest supply current (700µA), though input voltage range is constrained to 7V ~ 18V. The MAX875BESA+ and MAX875BESA+T variants provide ±0.06% tolerance within the same temperature and voltage constraints.

For applications where tolerance relaxation is acceptable, REF02HSZ (±0.5%) and REF02CSZ (±1%) provide cost-effective alternatives with extended input voltage range (8V ~ 36V) and -40°C ~ 85°C operating temperature.

The ADR02WARZ-REEL7 is designated for automotive applications and operates within -40°C ~ 125°C with input voltage limited to 7V ~ 26V.

Frequently Asked Questions (FAQ)

Q: Can MAX875AESA+ directly replace REF5050MDREP in all applications?

A: MAX875AESA+ is compatible from a package and output specification perspective (5V, 10mA, 8-SOIC). However, it operates only to 85°C maximum, whereas REF5050MDREP extends to 125°C. Additionally, MAX875AESA+ input voltage range is 7V ~ 18V compared to REF5050MDREP's 5.2V ~ 18V. Verify application temperature and input voltage requirements before substitution.

Q: What is the primary difference between ADR02ARZ-REEL and ADR02ARZ-REEL7?

A: Both parts are electrically identical with ±0.1% tolerance, 5V output, 10mA current, and 8-SOIC package. The designation difference reflects packaging reel configuration. Both are suitable substitutes where tolerance relaxation from ±0.05% to ±0.1% is acceptable.

Q: Is REF02CSZ suitable for precision voltage reference applications?

A: REF02CSZ provides ±1% tolerance, which is significantly relaxed compared to REF5050MDREP's ±0.05%. This part is suitable only for applications where voltage reference accuracy is non-critical. For precision applications, ADR02BRZ (±0.06%) or MAX875AESA+ (±0.04%) are more appropriate.

Q: What are the packaging differences among substitute parts?

A: Substitute parts are supplied in either Tube or Cut Tape & Digi-Reel packaging. All maintain the same 8-SOIC physical package format. Packaging type affects handling and automated assembly compatibility but does not alter electrical performance.

Q: Can ADR02WARZ-REEL7 be used in non-automotive applications?

A: ADR02WARZ-REEL7 is designated for automotive grade applications but is electrically compatible with non-automotive designs. It operates within -40°C ~ 125°C with ±0.1% tolerance and 5V output. Input voltage range is constrained to 7V ~ 26V. Verify that application input voltage requirements fall within this range.

Q: Which substitute offers the best temperature coefficient performance?

A: ADR02BRZ and ADR02BRZ-REEL7 provide the lowest temperature coefficient at 3ppm/°C, compared to REF5050MDREP's 6.5ppm/°C. This results in superior output voltage stability across temperature variations.

Q: What is the minimum input voltage requirement for each substitute group?

A: REF5050MDREP requires minimum 5.2V input. ADR02 series (all variants) require minimum 7V input. MAX875 series require minimum 7V input. REF02 series require minimum 8V input. Verify power supply specifications before substitution.
