ZXSC440X8TA Equivalent & Substitute Parts

Part Overview

The ZXSC440X8TA is a Photoflash Capacitor Charger PMIC manufactured by Diodes Incorporated in 8-MSOP packaging. This component is designed for photoflash charging applications requiring efficient power management in compact form factors. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines. Substitute parts must maintain compatibility with the original supply voltage range (1.8V ~ 8V), operating temperature specifications (-40°C ~ 85°C), and surface mount installation requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ZXSC440X8TA are selected based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Category: Power Management (PMIC)
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 85°C (minimum requirement)
• Voltage Supply Compatibility: Overlap with 1.8V ~ 8V range
• RoHS3 Compliance: Required for regulatory alignment
• Product Status: Active or readily available inventory

Substitution Logic: The ZXSC440X8TA operates within a 1.8V ~ 8V supply range with 220µA supply current. Substitute parts must support this voltage envelope and maintain equivalent thermal operating specifications. All identified substitutes are ROHS3 compliant, surface mount PMICs with active product status and confirmed inventory availability. Package form factors differ from the original 8-MSOP due to functional requirements of substitute architectures, but all maintain surface mount compatibility for PCB integration.

Parameter Comparison

Engineering Selection Recommendations

STBP120AVDK6F (STMicroelectronics) provides the closest voltage supply compatibility with the original ZXSC440X8TA, supporting 1.2V ~ 28V with 170µA supply current. This part maintains MSL 1 rating and active product status with substantial inventory. The 10-TDFN package accommodates surface mount integration requirements.

TPS65053RGER (Texas Instruments) operates within 2.5V ~ 6V supply range, overlapping the upper portion of the original specification. This part is actively produced with 6100 units in stock. The 24-VQFN package provides alternative form factor for applications requiring multi-channel power management. MSL rating of 2 requires one-year moisture control during storage and handling.

ADM1191-2ARMZ-R7 (Analog Devices Inc.) supports 3.15V ~ 26V supply range with 1.7mA supply current and MSL 1 rating. Active product status with 5080 units available. The 10-MSOP package maintains dimensional similarity to the original 8-MSOP form factor.

LTC1699EGN-80#TRPBF (Analog Devices Inc.) operates within 2.7V ~ 5.5V supply range with 350µA supply current. Active product status with limited inventory (701 units). The 16-SSOP package represents a larger footprint compared to the original 8-MSOP.

All substitute parts maintain ROHS3 compliance, -40°C ~ 85°C operating temperature specifications, and surface mount installation compatibility required for direct application consideration.

Frequently Asked Questions (FAQ)

Q: Can STBP120AVDK6F directly replace ZXSC440X8TA in existing designs? A: STBP120AVDK6F maintains voltage supply compatibility (1.2V ~ 28V encompasses the original 1.8V ~ 8V range) and identical operating temperature specifications. Package form factor differs (10-TDFN vs. 8-MSOP), requiring PCB layout modification. Functional application requirements must be evaluated for compatibility.

Q: What is the significance of MSL rating differences between substitutes? A: MSL 1 (Unlimited) rated parts such as STBP120AVDK6F, ADM1191-2ARMZ-R7, and LTC1699EGN-80#TRPBF require no moisture control during storage. TPS65053RGER carries MSL 2 (1 Year) rating, requiring storage in controlled humidity environments and baking procedures if moisture absorption limits are exceeded.

Q: Why do substitute parts have different supply current specifications? A: Supply current reflects the quiescent power consumption of each PMIC architecture. STBP120AVDK6F (170µA) and ZXSC440X8TA (220µA) operate in comparable current ranges. ADM1191-2ARMZ-R7 (1.7mA) and LTC1699EGN-80#TRPBF (350µA) reflect different functional implementations and feature sets within the Power Management category.

Q: How does package selection affect substitution feasibility? A: The original ZXSC440X8TA uses 8-MSOP (0.118", 3.00mm Width) packaging. Substitute parts employ different packages: ADM1191-2ARMZ-R7 (10-MSOP), STBP120AVDK6F (10-TDFN), LTC1699EGN-80#TRPBF (16-SSOP), and TPS65053RGER (24-VQFN). Package differences require PCB redesign for pin routing and thermal management. Surface mount compatibility is maintained across all options.

Q: Which substitute offers the best inventory availability? A: ZXSC440X8TA maintains 27188 units in stock despite discontinued status. Among active substitutes, STBP120AVDK6F provides highest availability with 15481 units, followed by TPS65053RGER (6100 units), ADM1191-2ARMZ-R7 (5080 units), and LTC1699EGN-80#TRPBF (701 units).

Q: Are all substitutes ROHS3 compliant? A: All listed substitute parts maintain ROHS3 compliance, matching the original ZXSC440X8TA regulatory status. REACH status is unaffected for all parts, and ECCN classification remains EAR99 across the complete substitute list.
