SN74HC175N-P2 Equivalent & Substitute Parts

Part Overview

The SN74HC175N-P2 is a D-type flip-flop logic integrated circuit manufactured by Texas Instruments, classified within the 74HC series. This device functions as a 1-element, 4-bit positive edge-triggered flip-flop with complementary outputs and master reset capability. The component is housed in a 16-DIP (0.300", 7.62mm) through-hole package and operates across a supply voltage range of 2V to 6V.

The SN74HC175N-P2 maintains Active product status and is ROHS3 compliant. Identifying equivalent substitute parts is necessary when the specific packaging variant (P2 suffix with tube packaging) is unavailable, while maintaining identical electrical and mechanical performance characteristics for circuit continuity and design flexibility.

Substitute Part Grouping Explanation

Substitution of the SN74HC175N-P2 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Identical logic function (D-type flip-flop, 1 element, 4-bit configuration)
• Matching trigger type (positive edge)
• Identical output type (complementary)
• Matching master reset function
• Equivalent clock frequency (60 MHz)
• Identical propagation delay specifications (26 ns @ 6V, 50pF)
• Matching supply voltage range (2V ~ 6V)
• Identical output current ratings (5.2 mA high and low)
• Matching quiescent current (8 µA)
• Identical input capacitance (3 pF)

Mechanical Equivalence Criteria:

• Identical package type (16-DIP, 0.300", 7.62mm)
• Through-hole mounting compatibility
• Same pin configuration and footprint

Compliance Equivalence Criteria:

• ROHS3 compliance maintained
• Active product status

The SN74HC175N (without P2 suffix) qualifies as a parametric equivalent substitute. The P2 suffix denotes packaging format (tube) rather than electrical or functional differentiation. The base part number SN74HC175 represents the core device specification across all packaging variants.

Parameter Comparison

Engineering Selection Recommendations

The SN74HC175N serves as a direct parametric equivalent to the SN74HC175N-P2. Both components maintain identical electrical specifications, mechanical dimensions, and compliance certifications. Selection between these variants is determined by packaging and supply chain availability rather than functional or performance differentiation.

Both parts maintain Active product status from Texas Instruments and satisfy ROHS3 compliance requirements. The 16-DIP through-hole package format is consistent across both variants, ensuring PCB footprint and assembly process compatibility.

When the SN74HC175N-P2 is unavailable, the SN74HC175N provides equivalent functionality without circuit redesign or performance compromise. Inventory availability and lead time considerations may influence selection between packaging variants of the same base product number.

Frequently Asked Questions (FAQ)

Q: What is the difference between SN74HC175N-P2 and SN74HC175N?
