Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4541BPWRG4 is determined by the following critical parameters:

• Package compatibility: 14-TSSOP surface mount form factor
• Functional classification: Programmable Timer IC
• Supply voltage range: Minimum 3V to 20V support
• Operating temperature range: -55°C to 125°C coverage
• RoHS and environmental compliance: ROHS3 Compliant status
• Moisture sensitivity: MSL 1 rating

The CD4541BPWRG4 has two qualified substitutes that meet these criteria. Both alternatives maintain identical packaging, compliance certifications, and core functional specifications while differing in frequency capability and supply voltage upper limits.

Parameter Comparison

Engineering Selection Recommendations

CD4541BPWR is the primary substitute for CD4541BPWRG4. Both parts are manufactured by Texas Instruments with identical electrical specifications, frequency rating, and supply voltage range. The CD4541BPWR maintains active product status with higher inventory availability (5144 pcs in stock versus 815 pcs for the original part). Packaging differs only in format designation (Tape & Reel versus standard packaging), with no impact on component functionality or PCB integration.

MC14541BDTR2G is a secondary substitute manufactured by onsemi. This part maintains identical package geometry, temperature range, and compliance certifications. The maximum supply voltage is reduced to 18V (versus 20V for the CD4541 series), and the frequency capability is increased to 3MHz. This substitute is suitable for applications where the 100kHz frequency specification is not a limiting factor and the 18V maximum supply voltage is compatible with system design requirements.

Both substitutes are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can CD4541BPWR be used as a direct replacement for CD4541BPWRG4?

A: Yes. Both parts share identical electrical specifications, frequency rating (100kHz), supply voltage range (3V ~ 20V), operating temperature range (-55°C ~ 125°C), and 14-TSSOP package geometry. The only difference is packaging format (Tape & Reel versus standard). No circuit modifications are required.

Q: What are the key differences between CD4541BPWR and MC14541BDTR2G?

A: The primary differences are manufacturer (Texas Instruments versus onsemi), frequency capability (100kHz versus 3MHz), and maximum supply voltage (20V versus 18V). Both maintain identical package form factor and temperature range. Selection depends on whether the application requires the 100kHz frequency specification and whether the 18V maximum supply voltage is acceptable.

Q: Is the 14-TSSOP package identical across all three parts?

A: Yes. All three parts use the 14-TSSOP package with 0.173" width and 4.40mm dimensions. PCB footprints and mounting procedures are identical.

Q: Are all substitutes RoHS compliant?

A: Yes. CD4541BPWR and MC14541BDTR2G are both ROHS3 compliant with MSL 1 rating, matching the original CD4541BPWRG4 specifications.

Q: Which substitute should be selected for new designs?

A: CD4541BPWR is recommended for direct replacement applications requiring 100kHz operation and 20V maximum supply voltage. MC14541BDTR2G is suitable for applications where higher frequency capability (3MHz) is beneficial and the 18V maximum supply voltage is compatible with system requirements.
