MCP6569T-E/SL Equivalent & Substitute Parts

Part Overview

The MCP6569T-E/SL is a general-purpose CMOS comparator with open-drain output, manufactured by Microchip Technology. This 4-element comparator operates across a supply voltage range of 1.8V to 5.5V and is housed in a 14-SOIC surface-mount package. The device is currently in active production status with 3,000,300 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for specific assembly processes, or when design requirements necessitate different electrical performance characteristics within compatible parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCP6569T-E/SL is determined by the following critical parameters:

Primary Substitution Criteria:

• Number of Elements: 4 comparators
• Output Type: CMOS, Open-Drain
• Package compatibility: 14-pin surface-mount or through-hole variants
• Supply voltage overlap within operating range
• Operating temperature range coverage

Substitute Parts Identified:

1. MCP6569-E/SL (Microchip Technology) - Direct packaging variant with identical electrical specifications and 14-SOIC package
2. TLV3404CPWR (Texas Instruments) - Alternative manufacturer with 14-TSSOP package; wider supply voltage range (2.5V ~ 16V, ±1.25V ~ 8V); different electrical performance characteristics
3. TLV3404ID (Texas Instruments) - Alternative manufacturer with 14-SOIC package; product status is Obsolete; wider supply voltage range (2.7V ~ 16V, ±1.35V ~ 8V)
4. TLV3404IN (Texas Instruments) - Alternative manufacturer with 14-DIP through-hole package; product status is Last Time Buy; wider supply voltage range (2.7V ~ 16V, ±1.35V ~ 8V)

Parameter Comparison

Engineering Selection Recommendations

MCP6569-E/SL is the preferred direct substitute when the original MCP6569T-E/SL becomes unavailable. Both parts share identical electrical specifications, the same 14-SOIC package, and active product status. The only difference is packaging format (Tube vs. standard packaging), which does not affect electrical performance or board-level compatibility.

TLV3404CPWR is suitable for applications requiring extended supply voltage range (up to 16V) and improved CMRR/PSRR performance. However, this part uses a 14-TSSOP package instead of 14-SOIC, requiring PCB layout modifications. The operating temperature range is limited to 0°C ~ 70°C, which may not meet designs requiring -40°C ~ 125°C operation. This part maintains active product status.

TLV3404ID offers the same 14-SOIC package as the original part with extended supply voltage capability and superior noise rejection. However, this part has Obsolete product status, indicating end-of-life designation. Use only when no other alternatives are available and existing inventory can be secured.

TLV3404IN provides a through-hole 14-DIP package alternative for designs using through-hole assembly. Extended supply voltage range and improved CMRR/PSRR are available. Product status is Last Time Buy, indicating limited future availability. Operating temperature range matches the original specification (-40°C ~ 125°C).

All substitute parts maintain ROHS3 compliance and are suitable for applications requiring equivalent regulatory certifications.

Frequently Asked Questions (FAQ)

Q: Can MCP6569-E/SL be used as a direct replacement for MCP6569T-E/SL?

A: Yes. Both parts are manufactured by Microchip Technology with identical electrical specifications, operating temperature range, and 14-SOIC package. The difference in packaging format (Tube) does not affect electrical performance or PCB compatibility.

Q: What are the key differences between MCP6569T-E/SL and TLV3404 variants?

A: The primary differences are: (1) Manufacturer (Microchip vs. Texas Instruments), (2) Supply voltage range (MCP6569 operates at 1.8V ~ 5.5V; TLV3404 variants operate at 2.5V ~ 16V or 2.7V ~ 16V), (3) Propagation delay (MCP6569: 80ns; TLV3404: 300µs), (4) Quiescent current (MCP6569: 130µA; TLV3404: 950nA), and (5) Package options vary by variant.

Q: Which substitute part should be selected for low-power applications?

A: TLV3404 variants offer significantly lower quiescent current (950nA vs. 130µA), making them suitable for battery-powered or low-power designs. However, verify that the extended supply voltage range and different propagation delay characteristics are compatible with your circuit requirements.

Q: Are TLV3404ID and TLV3404IN suitable for new designs?

A: TLV3404ID has Obsolete product status and TLV3404IN has Last Time Buy status. Both parts should not be selected for new designs. Use TLV3404CPWR (Active status) or MCP6569-E/SL for new applications.

Q: What package considerations apply when selecting a substitute?

A: MCP6569T-E/SL and MCP6569-E/SL use 14-SOIC surface-mount packages with identical footprints. TLV3404CPWR uses 14-TSSOP, requiring different PCB layout. TLV3404IN uses 14-DIP through-hole package, requiring through-hole assembly capability. Verify PCB design compatibility before part selection.

Q: Do all substitute parts meet the same temperature operating range?

A: No. MCP6569T-E/SL, MCP6569-E/SL, TLV3404ID, and TLV3404IN operate across -40°C ~ 125°C. TLV3404CPWR is limited to 0°C ~ 70°C. Verify temperature requirements for your application before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, meeting equivalent environmental and regulatory requirements.
