ADH025-00E Equivalent & Substitute Parts

Part Overview

The ADH025-00E is a magnetic switch with omnipolar sensing capability, manufactured by NVE Corp/Sensor Products. This Hall Effect-based digital switch operates across a wide supply voltage range (4.5V to 30V) and is housed in an 8-MSOP surface mount package. The part is currently discontinued at DiGi Electronics, making substitute identification essential for ongoing design support and procurement continuity. The ADH025-00E provides open collector output with a maximum output current of 20mA and operates reliably across the industrial temperature range of -40°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADH025-00E is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Omnipolar switch function (sensing both north and south magnetic poles)
• Surface mount package compatibility (8-MSOP, 0.118" width, 3.00mm)
• Supply voltage range overlap (minimum 4.5V to 30V support)
• Operating temperature range coverage (-40°C to 125°C)
• Output configuration suitable for open collector or digital logic integration
• RoHS3 compliance and MSL Level 1 rating

Allowed Parameter Variations:

• Sensing range thresholds may differ within practical application tolerances
• Supply current consumption may vary
• Output current capacity may exceed minimum requirements
• Technology implementation (Hall Effect vs. Magnetoresistive) is acceptable if functional equivalence is maintained
• Packaging format (Tape & Reel vs. bulk) does not affect electrical compatibility

The ADH025-00E-TR qualifies as a direct substitute based on these criteria, despite differences in technology implementation and specific sensing thresholds.

Parameter Comparison

Engineering Selection Recommendations

ADH025-00E-TR as Primary Substitute:

The ADH025-00E-TR is the qualified substitute for the discontinued ADH025-00E. Both parts share identical supply voltage specifications (4.5V to 30V), operating temperature range (-40°C to 125°C), package geometry (8-MSOP, 0.118" width), and regulatory compliance (ROHS3, MSL Level 1). The ADH025-00E-TR maintains active product status with confirmed inventory availability (1711 pieces), ensuring procurement continuity.

Key Compatibility Factors:

The ADH025-00E-TR operates within the same omnipolar magnetic sensing classification and surface mount package footprint. Both parts support the full industrial temperature range and wide supply voltage envelope required for robust field deployment. The substitute part's digital output configuration and magnetoresistive technology provide functional equivalence to the original Hall Effect design.

Compliance and Certification:

Both the original and substitute parts maintain ROHS3 compliance and carry identical MSL Level 1 ratings, confirming suitability for standard PCB assembly processes without moisture sensitivity constraints. REACH status remains unaffected for both variants, and both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Inventory and Availability:

The ADH025-00E-TR is available in Tape & Reel packaging format, which is standard for high-volume production environments. The original ADH025-00E, while discontinued at DiGi Electronics, maintains 697 pieces in new original stock through alternative channels.

Frequently Asked Questions (FAQ)

Q: Can the ADH025-00E-TR directly replace the ADH025-00E in existing designs?

A: Yes. Both parts share identical supply voltage ranges (4.5V to 30V), operating temperature specifications (-40°C to 125°C), and 8-MSOP package geometry. The ADH025-00E-TR is pin-compatible and functionally equivalent for omnipolar magnetic switch applications.

Q: What is the difference between Hall Effect and Magnetoresistive technology in these parts?

A: The ADH025-00E uses Hall Effect sensing, while the ADH025-00E-TR uses Magnetoresistive technology. Both technologies detect magnetic field polarity and provide omnipolar switch functionality. The sensing threshold values differ slightly (±1.1mT vs. 1.2mT trip), but both operate within practical application tolerances for magnetic switch circuits.

Q: Are there output configuration differences between these parts?

A: The ADH025-00E provides open collector output (20mA maximum), while the ADH025-00E-TR provides digital output (24mA maximum). Both output types are compatible with standard logic-level circuits and microcontroller inputs. The ADH025-00E-TR's higher output current capacity provides additional design margin.

Q: Do both parts require the same PCB footprint?

A: Yes. Both the ADH025-00E and ADH025-00E-TR use the 8-MSOP package with identical pin spacing (0.118" width, 3.00mm). No PCB layout modifications are required for substitution.

Q: What is the significance of the Tape & Reel (TR) packaging designation?

A: The TR designation indicates the ADH025-00E-TR is supplied in continuous tape and reel format, standard for automated pick-and-place assembly. This packaging format does not affect electrical performance or pin compatibility; it only impacts procurement and assembly logistics.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the ADH025-00E and ADH025-00E-TR are ROHS3 compliant with MSL Level 1 ratings, confirming compatibility with standard lead-free PCB assembly processes without moisture sensitivity constraints.

Q: What supply current should be budgeted for the substitute part?

A: The ADH025-00E-TR has a maximum supply current of 6.5mA, compared to 4.5mA for the original ADH025-00E. Circuit designs should accommodate this higher current draw, though the difference remains negligible in most applications.

Q: Is the ADH025-00E-TR currently available for procurement?

A: Yes. The ADH025-00E-TR maintains active product status with 1711 pieces confirmed in new original stock, ensuring reliable procurement availability for production and replacement applications.
