MAX810STR Equivalent & Substitute Parts

Part Overview

The MAX810STR is a single-channel power supply supervisor IC manufactured by onsemi, designed for simple reset and power-on reset applications. This component operates as a push-pull, totem pole output supervisor with a 2.93V threshold voltage and 140ms minimum reset timeout. The MAX810STR is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Engineering Selection Recommendations

For Direct Replacement (Obsolete to Obsolete): MAX810STRG provides identical electrical performance to MAX810STR with RoHS3 compliance upgrade and Cut Tape packaging. This is the closest equivalent for legacy system maintenance.

For Active Product Substitution: ADM810SARTZ-REEL7, MAX810SEUR+T, MIC810SUY-TR, STM810SWX6F, TCM810SVNB713, and TCM810SVLB713 are all active products meeting the core electrical specifications. All substitute parts carry RoHS3 compliance, addressing regulatory requirements that the original MAX810STR does not meet.

Temperature Range Considerations: ADM810SARTZ-REEL7 and TCM810SVNB713 support extended operating temperature to -40°C ~ 125°C (TA), providing margin beyond the MAX810STR specification of -40°C ~ 105°C (TJ). MIC810SUY-TR and STM810SWX6F operate to -40°C ~ 85°C (TA), which is narrower than the original part.

Package Selection: TCM810SVLB713 uses SC-70-3 package instead of SOT-23-3. This requires PCB layout modification but maintains electrical equivalence. All other substitutes use SOT-23-3 package, enabling direct board-level replacement.

Compliance Status: All substitute parts are RoHS3 compliant, whereas the original MAX810STR is RoHS non-compliant. This is significant for new designs and systems requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can MAX810STRG be used as a direct replacement for MAX810STR?

A: Yes. MAX810STRG is electrically identical to MAX810STR with the same voltage threshold (2.93V), output configuration (push-pull, totem pole), reset logic (active high), and reset timeout (140ms minimum). The primary difference is packaging format (Cut Tape vs. Tube) and RoHS3 compliance status. Both are classified as obsolete products.

Q: What is the key difference between onsemi MAX810 variants and cross-manufacturer substitutes?

A: All parts share identical electrical specifications: 2.93V threshold, push-pull totem pole output, active high reset, and 140ms minimum timeout. Cross-manufacturer substitutes (Analog Devices ADM810, Microchip MIC810/TCM810, STMicroelectronics STM810) differ in operating temperature range, product status (active vs. obsolete), and packaging options. All cross-manufacturer substitutes are active products with RoHS3 compliance.

Q: Does operating temperature range affect substitution compatibility?

A: Operating temperature range does not affect electrical substitution compatibility for the core supervisor function. However, system design must account for the specified range. MIC810SUY-TR and STM810SWX6F operate to 85°C maximum (TA), which is narrower than MAX810STR (105°C TJ). ADM810SARTZ-REEL7 and TCM810SVNB713 extend to 125°C (TA), providing additional margin.

Q: Can TCM810SVLB713 (SC-70-3 package) replace MAX810STR (SOT-23-3 package)?

A: TCM810SVLB713 is electrically equivalent but uses SC-70-3 package instead of SOT-23-3. This requires PCB layout modification due to different pin spacing and footprint. Electrical performance is identical. TCM810SVNB713 provides the same electrical specifications in SOT-23-3 package for direct board-level replacement.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed (MAX810STRG, MAX810SN293D2T1G, ADM810SARTZ-REEL7, MAX810SEUR+T, MIC810SUY-TR, STM810SWX6F, TCM810SVLB713, TCM810SVNB713) are RoHS3 compliant. The original MAX810STR is RoHS non-compliant, making compliance upgrade a key benefit of substitution.

Q: Which substitute part has the widest operating temperature range?

A: ADM810SARTZ-REEL7 and TCM810SVNB713 both support -40°C ~ 125°C (TA), providing the widest operating range among active substitutes. This exceeds the original MAX810STR specification of -40°C ~ 105°C (TJ).

Q: What is the inventory status of substitute parts?

A: ADM810SARTZ-REEL7 has 17,170 pcs in stock. TCM810SVNB713 has 4,936 pcs. MIC810SUY-TR has 10,310 pcs. STM810SWX6F has 3,420 pcs. MAX810SEUR+T has 1,498 pcs. TCM810SVLB713 has 1,070 pcs. MAX810SN293D2T1G has 627 pcs. MAX810STRG has 4,962 pcs.
