Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP6601GU-P are identified through parametric equivalence. All substitute parts share identical electrical specifications, mechanical packaging, and functional characteristics that define substitutability for this product category:

Key Parameters Determining Substitution:

• Motor Type (Stepper: Bipolar; AC/DC: Brushed DC)
• Output Configuration (Half Bridge with 4 outputs)
• Current Rating (2.5A output)
• Supply Voltage Range (4.5V ~ 35V)
• Load Voltage Support (3.3V, 5V)
• Operating Temperature Range (-40°C ~ 125°C)
• Package Type (24-VFQFN Exposed Pad)
• Step Resolution Capability (1, 1/2, 1/4, 1/8)

All substitute parts maintain these specifications without deviation. Substitution is based on functional and electrical equivalence within the same product category and packaging standard.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—MP6601GU-Z, MP6500GU-P, and MP6500GU-Z—are parametrically equivalent to the MP6601GU-P and are suitable for direct replacement in applications requiring bipolar stepper motor driving with the specified electrical and mechanical characteristics.

Selection among equivalent parts may be based on:

• Product Availability: Inventory levels vary across part numbers. MP6500GU-Z maintains the highest inventory (9992 pcs), followed by MP6601GU-Z (6099 pcs), MP6500GU-P (1369 pcs), and MP6601GU-P (919 pcs).
• Compliance Requirements: All parts maintain identical RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for the same applications.
• Packaging Variant: The suffix designation (GU-P vs. GU-Z) indicates packaging tape configuration. Both variants are functionally equivalent and differ only in tape reel specifications for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can MP6500GU-P replace MP6601GU-P in existing designs?

A: Yes. Both parts are parametrically equivalent across all electrical specifications, output configuration, current rating, voltage ranges, operating temperature, and package type. Direct substitution is supported without circuit modification.

Q: What is the difference between MP6601GU-P and MP6601GU-Z?

A: The suffix designates the tape and reel packaging configuration. Both parts are electrically and functionally identical. The selection between GU-P and GU-Z variants depends on the tape reel specification required for your assembly equipment.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts—MP6601GU-Z, MP6500GU-P, and MP6500GU-Z—maintain ROHS3 compliance and REACH unaffected status identical to the MP6601GU-P.

Q: Can these parts be used interchangeably in printer applications?

A: Yes. All substitute parts are rated for printer applications and support the same stepper motor control functionality with bipolar motor type, half-bridge output configuration, and step resolution options (1, 1/2, 1/4, 1/8).

Q: What is the moisture sensitivity level for these parts?

A: All parts carry MSL 2 (1 Year) rating, indicating standard moisture sensitivity handling requirements for surface mount components with a one-year floor life under controlled storage conditions.

Q: Are there any differences in operating temperature range among substitute parts?

A: No. All parts operate across the identical temperature range of -40°C to 125°C (junction temperature), supporting the same thermal operating envelope.
