Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4013BCMX is determined by the following critical parameters:

• Package compatibility: 14-SOIC form factor (0.154", 3.90mm Width) for direct PCB footprint compatibility
• Functional equivalence: Dual D-type flip-flop with complementary outputs, set/preset and reset capability
• Electrical specifications: Supply voltage range, propagation delay, output current drive, and operating temperature range
• Trigger type: Positive edge triggering
• Series classification: 4000B logic family

Substitute parts are grouped into two categories based on package and electrical performance characteristics:

Category 1: Direct Package Equivalents (14-SOIC 0.154", 3.90mm) Parts with identical package dimensions and electrical performance suitable for direct replacement in existing designs.

Category 2: Alternative Package Variants (14-SOIC 0.209", 5.30mm) Parts with the same functional and electrical specifications but different package width, requiring PCB layout verification before substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Direct Replacement - Active Status)

MC14013BDR2G and MC14013BDG from onsemi provide the closest electrical match to the CD4013BCMX with active product status. Both maintain the same package footprint (14-SOIC 0.154", 3.90mm), dual D-type flip-flop configuration, and complementary output structure. The extended supply voltage range (3V ~ 18V) provides improved design margin compared to the original specification (3V ~ 15V). These parts are recommended for designs requiring minimal performance deviation from the original CD4013BCMX.

Performance-Enhanced Substitutes (Active Status)

CD4013BM and CD4013BM96 from Texas Instruments offer improved electrical performance with 24 MHz clock frequency (versus 15.5 MHz), reduced propagation delay (90 ns versus 120 ns), and lower output current (6.8 mA versus 8.8 mA). These parts maintain identical package footprint and functional architecture. The enhanced performance characteristics make these suitable for designs where improved speed or reduced power consumption is beneficial.

Automotive-Qualified Substitute

HCF4013YM013TR from STMicroelectronics is AEC-Q100 qualified and suitable for automotive applications. This part provides 24 MHz clock frequency, 90 ns propagation delay, and extended supply voltage range (3V ~ 20V). The automotive qualification and active product status make this appropriate for automotive-grade system designs.

High-Performance Substitute

HEF4013BT,653 and HEF4013BT-Q100J from Nexperia USA Inc. deliver the highest performance specifications with 40 MHz clock frequency and 60 ns propagation delay. The HEF4013BT-Q100J variant includes AEC-Q100 automotive qualification. These parts are suitable for applications requiring maximum speed performance within the 4000B logic family.

Alternative Package Consideration

CD4013BNSR from Texas Instruments provides equivalent electrical performance to CD4013BM and CD4013BM96 but uses a wider 14-SOIC package (0.209", 5.30mm). This part requires PCB layout verification to confirm footprint compatibility before substitution.

Frequently Asked Questions (FAQ)

Q: Can MC14013BDR2G directly replace CD4013BCMX on existing PCBs?

A: Yes. MC14013BDR2G maintains identical 14-SOIC (0.154", 3.90mm) package dimensions and pinout. The electrical specifications are compatible with the original design, with the added benefit of extended supply voltage range (3V ~ 18V versus 3V ~ 15V).

Q: What is the difference between CD4013BM and CD4013BM96?

A: Both parts are from Texas Instruments with identical electrical specifications and 14-SOIC (0.154", 3.90mm) packaging. The primary difference is packaging format: CD4013BM is supplied in Tube, while CD4013BM96 is supplied in Cut Tape (CT) & Digi-Reel format.

Q: Why does CD4013BNSR have a different package width?

A: CD4013BNSR uses a 14-SOIC package with 0.209" (5.30mm) width, compared to the standard 0.154" (3.90mm) width. This wider package requires verification of PCB footprint compatibility before substitution. The functional and electrical specifications remain equivalent to other CD4013 variants.

Q: Is HEF4013BT,653 suitable for designs with tight timing requirements?

A: Yes. HEF4013BT,653 provides the fastest performance in the substitute list with 40 MHz clock frequency and 60 ns maximum propagation delay. This makes it suitable for applications requiring improved speed performance compared to the original CD4013BCMX (15.5 MHz, 120 ns).

Q: What is the significance of AEC-Q100 qualification on HCF4013YM013TR and HEF4013BT-Q100J?

A: AEC-Q100 qualification indicates these parts meet automotive industry reliability and quality standards. These variants are appropriate for automotive applications and systems requiring automotive-grade component certification.

Q: Can I use HEF4013BT,653 in applications originally designed for CD4013BCMX?

A: Yes, with design verification. HEF4013BT,653 maintains the same 14-SOIC (0.154", 3.90mm) package and dual D-type flip-flop functionality. However, the improved performance characteristics (40 MHz versus 15.5 MHz, 60 ns versus 120 ns propagation delay) and lower output current (3.4 mA versus 8.8 mA) require confirmation that the original design does not depend on the slower timing or higher current drive of the CD4013BCMX.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Tube, Cut Tape (CT) & Digi-Reel, and Tape & Reel (TR). Selection depends on production volume and assembly process requirements. All variants maintain the same electrical specifications and 14-SOIC form factor (except CD4013BNSR, which uses the wider 5.30mm variant).
