DPS1035FIA-13 Equivalent & Substitute Parts

Part Overview

The DPS1035FIA-13 is an active power management integrated circuit (PMIC) classified as a Power Switch/Driver with 1:1 ratio configuration. This USB Switch device operates at 4.6A maximum output current with 30mOhm typical on-resistance, housed in a 17-VFQFN Exposed Pad surface mount package. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across alternative manufacturer offerings or product variants within the same manufacturer's portfolio.

Substitute Part Grouping Explanation

The DPS1135FIA-13 qualifies as a manufacturer-recommended substitute for the DPS1035FIA-13 based on the following substitution criteria:

Mechanical Compatibility: Both parts utilize identical package specifications (17-VFQFN Exposed Pad) and surface mount mounting type, ensuring PCB layout and assembly process compatibility without redesign.

Electrical Core Parameters: Both devices maintain 1:1 input-to-output ratio configuration, identical load voltage range (4.5V ~ 24V), matching on-resistance specification (30mOhm typical), and identical operating temperature range (-40°C ~ 125°C TJ).

Regulatory & Compliance Alignment: Both parts carry ROHS3 compliance, MSL 1 rating, identical ECCN (EAR99) and HTSUS classifications, and active product status from the same manufacturer (Diodes Incorporated).

Key Differentiators: The DPS1135FIA-13 provides enhanced output current capability (5A vs. 4.6A), expanded fault protection features (includes Current Limiting Adjustable and Short Circuit protection), and different switch type classification (General Purpose vs. USB Switch). These differences represent functional enhancements rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

DPS1035FIA-13 Primary Selection: Maintain this part number for applications requiring USB Switch classification with 4.6A output current specification. Both parts carry active product status and identical ROHS3 compliance certification, supporting long-term supply chain stability.

DPS1135FIA-13 Substitution Eligibility: This part is suitable as a direct substitute when design margins permit the higher 5A output current rating and when General Purpose switch classification is acceptable for the application. The identical package, voltage range, on-resistance, and operating temperature specifications ensure mechanical and thermal compatibility. Enhanced fault protection features (Current Limiting Adjustable, Short Circuit) provide additional circuit protection without requiring design modification.

Compliance Continuity: Both parts maintain identical regulatory certifications (ROHS3, EAR99, HTSUS 8542.39.0001) and moisture sensitivity ratings, ensuring supply chain and manufacturing process compatibility.

Frequently Asked Questions (FAQ)

Q: Can DPS1135FIA-13 replace DPS1035FIA-13 in existing designs?

A: Yes, when the application's output current requirement does not exceed 5A and General Purpose switch classification is acceptable. The identical package (17-VFQFN Exposed Pad), voltage range (4.5V ~ 24V), on-resistance (30mOhm), and operating temperature range (-40°C ~ 125°C) ensure direct compatibility without PCB redesign or thermal re-analysis.

Q: What are the key electrical differences between these parts?

A: The primary differences are output current rating (DPS1035FIA-13: 4.6A maximum; DPS1135FIA-13: 5A maximum) and fault protection features. DPS1135FIA-13 includes Current Limiting (Adjustable) and Short Circuit protection in addition to the common protections (Over Temperature, Over Voltage, Reverse Current, UVLO).

Q: Are packaging and mounting specifications identical?

A: Yes. Both parts use 17-VFQFN Exposed Pad package with surface mount mounting type. No PCB layout modifications are required for substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts carry ROHS3 compliance, MSL 1 (Unlimited) rating, and identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: Which part should be selected for new designs?

A: Selection depends on application current requirements. For designs requiring 4.6A or less, either part is suitable. For designs with higher current margins or requiring enhanced short circuit protection, DPS1135FIA-13 is the appropriate choice. Both parts maintain active product status and equivalent long-term availability.
