AP2331W-7-01 Equivalent & Substitute Parts

Part Overview

The AP2331W-7-01 is a current switch regulator IC from Diodes Incorporated, designed for high-side current switching applications with a 200mA output capacity. This Surface Mount device operates across a 2.7V to 5.2V input voltage range and is housed in a SC-59-3 (SOT-23-3) package. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts maintain identical electrical specifications while offering different packaging formats and product status options.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts for the AP2331W-7-01 share the same base product number (AP2331) and maintain electrical equivalence across the following critical parameters:

• Input voltage range: 2.7V ~ 5.2V
• Output current: 200mA
• Function: High-side current switch
• Operating temperature: -40°C ~ 85°C
• Package type: TO-236-3 / SC-59 / SOT-23-3
• Compliance: ROHS3, REACH Unaffected, EAR99

Substitution differences are determined by packaging format (Cut Tape vs. Tape & Reel) and product status (Active vs. Discontinued). The supplier device package designation (SC-59-3 vs. SOT-23-3) indicates the specific tape format but does not affect electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

AP2331SA-7: Recommended for new designs and production environments requiring active product status. Available in both Cut Tape and Digi-Reel® packaging formats with unlimited moisture sensitivity level. Electrical specifications are identical to the discontinued AP2331W-7-01.

AP2331TDSA-7: Suitable for high-volume manufacturing requiring Tape & Reel format with active product status. Maintains identical electrical performance with unlimited MSL rating. The "TD" designation indicates tape format optimization for automated assembly.

AP2331W-7: Direct packaging equivalent to AP2331W-7-01 with active product status. Maintains SC-59-3 package format. MSL rating of 3 (168 Hours) requires controlled storage conditions compared to the unlimited MSL of other substitutes.

All substitutes comply with ROHS3, REACH Unaffected, and EAR99 classifications, matching the original part's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can AP2331SA-7 replace AP2331W-7-01 in existing designs? A: Yes. Both parts share identical electrical specifications (2.7V-5.2V input, 200mA output, -40°C to 85°C operation). The primary difference is packaging format and product status. AP2331SA-7 is available in SOT-23-3 package with active product status.

Q: What is the difference between SC-59-3 and SOT-23-3 package designations? A: SC-59-3 and SOT-23-3 refer to the same physical package (TO-236-3) but indicate different tape formats for automated assembly. SC-59-3 uses one tape configuration while SOT-23-3 uses another. Both are mechanically and electrically compatible.

Q: Why does AP2331W-7 have MSL 3 instead of MSL 1? A: MSL (Moisture Sensitivity Level) 3 requires storage at controlled humidity (≤60% RH) for up to 168 hours before soldering. MSL 1 (Unlimited) has no moisture sensitivity restrictions. For applications with extended storage or variable environmental conditions, AP2331SA-7 or AP2331TDSA-7 with MSL 1 are preferred.

Q: Which substitute is best for high-volume production? A: AP2331TDSA-7 is optimized for high-volume manufacturing with Tape & Reel packaging and active product status. AP2331SA-7 offers flexibility with both Cut Tape and Digi-Reel® options for mixed production volumes.

Q: Are all substitutes ROHS3 and REACH compliant? A: Yes. All substitute parts (AP2331SA-7, AP2331TDSA-7, AP2331W-7) maintain ROHS3 Compliant and REACH Unaffected status, matching the original AP2331W-7-01 specifications.
