MM74HC165M Equivalent & Substitute Parts

Part Overview

The MM74HC165M is an 8-bit parallel-in/serial-out shift register manufactured by onsemi in a 16-SOIC surface mount package. This logic IC is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design support and procurement. The 74HC165 series provides parallel or serial to serial conversion functionality across the 2V to 6V supply voltage range, making it suitable for digital logic applications requiring data serialization.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MM74HC165M is determined by strict equivalence across the following parameters:

• Logic Type: Shift Register (8-bit configuration)
• Function: Parallel or Serial to Serial conversion
• Voltage Supply Range: 2V ~ 6V
• Package / Case: 16-SOIC form factor
• Output Type: Complementary
• Mounting Type: Surface Mount

Substitute parts are grouped into two categories:

Direct Substitutes (Functionally Identical): Parts that maintain all core electrical and mechanical parameters, differing only in manufacturer, product status, or packaging format. These include MC74HC165ADG, MC74HC165ADR2G, CD74HC165M, SN74HC165D, SN74HC165DR, SN74HC165DRG3, SN74HC165DT, and SN74HC165QDRQ1.

Similar Substitutes (Parameter Variations): Parts designated as similar due to minor package designation differences (16-SO vs. 16-SOIC) or automotive qualification grades. These include 74HC165D,653 and 74HC165D-Q100,118.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation for Active Designs:

MC74HC165ADR2G (onsemi) or SN74HC165DR (Texas Instruments) are preferred for new designs. Both parts are active, ROHS3 compliant, and available in high volume. MC74HC165ADR2G offers extended operating temperature range (-55°C to 125°C) compared to the original MM74HC165M (-40°C to 85°C), providing improved thermal margin. SN74HC165DR maintains the original -40°C to 125°C operating range and is available through standard distribution channels.

For Automotive Applications:

SN74HC165QDRQ1 (Texas Instruments, AEC-Q100 qualified) or 74HC165D-Q100,118 (Nexperia, AEC-Q100 qualified) are appropriate selections when automotive-grade qualification is required.

For Existing Inventory Compatibility:

MC74HC165ADG (onsemi) provides direct substitution with tube packaging matching the original MM74HC165M format. This part is active and ROHS3 compliant, suitable for replacement in existing stock management scenarios.

Avoid:

CD74HC165M (Harris Corporation) is obsolete and RoHS non-compliant. SN74HC165D and SN74HC165DT are discontinued at DiGi Electronics and should not be selected for new procurement.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MM74HC165M with any of the listed substitutes?

A: Yes, all listed direct substitutes maintain the same 8-bit shift register function, 2V to 6V supply voltage range, and 16-SOIC package form factor. Electrical and mechanical compatibility is assured across all direct substitutes. Similar substitutes (74HC165D,653 and 74HC165D-Q100,118) use 16-SO package designation but are physically compatible with 16-SOIC footprints.

Q: What is the difference between packaging formats (Tube, Cut Tape & Digi-Reel, Tape & Reel)?

A: Packaging format affects procurement and handling but not electrical performance. Tube packaging is suitable for manual assembly or small-volume orders. Cut Tape & Digi-Reel format is standard for automated pick-and-place assembly. Tape & Reel format is optimized for high-volume production. Select based on your assembly process requirements.

Q: Why does MC74HC165ADR2G have a wider operating temperature range than MM74HC165M?

A: MC74HC165ADR2G operates from -55°C to 125°C, compared to MM74HC165M's -40°C to 85°C. This extended range reflects improved manufacturing processes and thermal design in the active part. For applications within the original -40°C to 85°C range, both parts are functionally equivalent.

Q: Is RoHS compliance important for my application?

A: ROHS3 compliance is mandatory for products sold in the European Union and increasingly required by global OEMs. All active substitutes listed are ROHS3 compliant. CD74HC165M is RoHS non-compliant and should not be used in new designs intended for EU markets.

Q: What does AEC-Q100 qualification mean?

A: AEC-Q100 is an automotive industry qualification standard. SN74HC165QDRQ1 and 74HC165D-Q100,118 carry this qualification, indicating suitability for automotive applications with enhanced reliability testing and traceability requirements.

Q: Can I use the Nexperia parts (74HC165D,653 and 74HC165D-Q100,118) as direct replacements?

A: Yes. These parts are functionally equivalent with identical electrical specifications. The package designation difference (16-SO vs. 16-SOIC) reflects minor nomenclature variation but represents the same physical form factor and pin configuration.
