HCTS541DMSR Equivalent & Substitute Parts

Part Overview

The HCTS541DMSR is a non-inverting buffer logic integrated circuit manufactured by Renesas Electronics Corporation. This device functions as an 8-bit buffer with 3-state output capability, designed for digital signal buffering and line driving applications in TTL-compatible systems. The part operates within the 4.5V to 5.5V supply voltage range and is housed in a 20-pin through-hole package (20-SBDIP).

The HCTS541DMSR is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity, ensure component availability for production, and support long-term system maintenance and repair operations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCTS541DMSR are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Compatibility Requirements:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 6mA, 6mA
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -55°C ~ 125°C (TA)

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole (for direct pin-compatible substitution)
• Package / Case: 20-CDIP (0.300", 7.62mm) (for direct pin-compatible substitution)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories: direct pin-compatible replacements (same package and mounting type) and functional equivalents with different packaging (surface mount alternatives requiring board redesign).

Parameter Comparison

Engineering Selection Recommendations

Direct Pin-Compatible Substitutes (No Board Redesign Required):

The SN54HCT541J manufactured by Texas Instruments is a direct pin-compatible substitute for the HCTS541DMSR. Both devices share identical electrical parameters (logic type, bit configuration, output type, current ratings, supply voltage, and operating temperature range) and identical mechanical specifications (20-CDIP through-hole package). The SN54HCT541J maintains ROHS3 compliance and is currently in active production status, ensuring long-term availability. This part is suitable for direct socket replacement without circuit board modifications.

The SNJ54HCT541J, also manufactured by Texas Instruments, is listed as a direct substitute in the original part documentation. This device shares the same electrical functionality and base product number (54HCT541) as the main part. The SNJ54HCT541J is in active production status and provides component availability for replacement applications.

Functional Equivalent with Different Packaging:

The HCTS541KMSR manufactured by Renesas Electronics is a functional equivalent that maintains all electrical parameters of the main part (logic type, bit configuration, output type, current ratings, supply voltage, and operating temperature range). However, this substitute uses surface-mount packaging (8-SOIC) instead of through-hole packaging (20-CDIP). The HCTS541KMSR is in active production status and ROHS3 compliant. Selection of this part requires circuit board redesign to accommodate the different package footprint and mounting technology.

Selection Criteria:

For applications requiring immediate component replacement without board redesign, select either the SN54HCT541J or SNJ54HCT541J. Both are through-hole mounted in 20-CDIP packages and provide direct compatibility.

For new designs or redesign projects where surface-mount technology is preferred, the HCTS541KMSR offers an active-status alternative from the original manufacturer with identical electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the HCTS541KMSR be used as a direct replacement for the HCTS541DMSR without board modifications?

A: No. The HCTS541KMSR uses 8-SOIC surface-mount packaging, while the HCTS541DMSR uses 20-CDIP through-hole packaging. Direct socket replacement is not possible. Circuit board redesign is required to accommodate the different package footprint and mounting method.

Q: Are the SN54HCT541J and SNJ54HCT541J pin-compatible with the HCTS541DMSR?

A: Yes. Both Texas Instruments parts use the same 20-CDIP through-hole package with identical pin configuration and electrical specifications. They are suitable for direct socket replacement.

Q: What is the difference between the SN54HCT541J and SNJ54HCT541J?

A: Both parts share the same base product number (54HCT541) and electrical specifications. The SNJ54HCT541J is listed in the original part documentation as a direct substitute. Specific differences in manufacturing or qualification levels are not provided in the available technical parameters.

Q: Do all substitute parts meet RoHS compliance requirements?

A: The SN54HCT541J and HCTS541KMSR are confirmed ROHS3 compliant. The SNJ54HCT541J RoHS status is not specified in the available data.

Q: What is the operating temperature range for all substitute parts?

A: The SN54HCT541J and HCTS541KMSR both operate across -55°C to 125°C (TA), matching the main part specification. The SNJ54HCT541J operating temperature range is not specified in the available technical data.

Q: Are these substitute parts currently in production?

A: The SN54HCT541J, SNJ54HCT541J, and HCTS541KMSR are all classified as active products. The original HCTS541DMSR is obsolete. Active production status ensures component availability for procurement.

Q: Can I use the HCTS541KMSR in a through-hole socket designed for the HCTS541DMSR?

A: No. The HCTS541KMSR is a surface-mount device (8-SOIC package) and cannot be installed in a through-hole socket. The package types are mechanically incompatible.

Q: What are the key electrical parameters that make these parts interchangeable?

A: Interchangeability is determined by matching logic type (Buffer, Non-Inverting), bit configuration (1 element, 8 bits per element), output type (3-State), current ratings (6mA output high and low), supply voltage range (4.5V to 5.5V), and operating temperature range (-55°C to 125°C). All listed substitutes meet these criteria.
