BA7230LS Equivalent & Substitute Parts

Part Overview

The BA7230LS is a signal encoder IC manufactured by Rohm Semiconductor, designed for NTSC video encoding applications in professional video systems. This component operates as a through-hole 24-SIP package and is classified as obsolete. Due to its obsolete status and limited availability in modern supply chains, identifying functionally compatible substitute components is essential for system redesign, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BA7230LS is determined by the following critical parameters:

• Encoding Function: The substitute must perform video signal encoding with NTSC standard support
• Voltage Supply Compatibility: The substitute must operate within or encompass the 4.5V ~ 5.5V supply range
• Regulatory Compliance: Both components must maintain ROHS3 compliance and EAR99 classification
• Moisture Sensitivity: MSL rating of 1 or better ensures equivalent handling requirements
• Application Domain: Professional video encoding applications

The AD723WARUZ-RL7 qualifies as a substitute based on these parameters. While it differs in mounting technology (surface mount versus through hole) and package form factor (28-TSSOP versus 24-SIP), it provides equivalent encoding functionality with broader voltage supply range support and active product status.

Parameter Comparison

Engineering Selection Recommendations

Selection between the BA7230LS and AD723WARUZ-RL7 should be based on the following factors:

BA7230LS: Retain for existing through-hole PCB designs where component replacement is not feasible. Verify remaining inventory against production requirements, as product status is obsolete and supply is finite.

AD723WARUZ-RL7: Implement for new designs or PCB redesigns requiring video encoding functionality. This component offers active product status, ensuring long-term availability and supply chain stability. The expanded voltage supply range (2.7V ~ 5.5V) provides additional design flexibility. Surface mount packaging requires PCB layout modification and assembly process compatibility verification.

Both components maintain equivalent regulatory compliance (ROHS3, EAR99) and moisture sensitivity ratings, ensuring equivalent handling and environmental performance.

Frequently Asked Questions (FAQ)

Q: Can the AD723WARUZ-RL7 directly replace the BA7230LS in existing through-hole designs?

A: Direct pin-for-pin replacement is not possible due to different package types (24-SIP through-hole versus 28-TSSOP surface mount). PCB redesign is required to accommodate the substitute component.

Q: What are the key functional differences between these encoders?

A: The BA7230LS performs NTSC signal encoding. The AD723WARUZ-RL7 performs RGB to NTSC/PAL encoding, providing additional color space conversion capability. Both support NTSC standard output.

Q: Is the AD723WARUZ-RL7 compatible with the 4.5V ~ 5.5V supply range of the original design?

A: Yes. The AD723WARUZ-RL7 operates across 2.7V ~ 5.5V for both analog and digital supplies, which encompasses the original 4.5V ~ 5.5V range.

Q: Are there any compliance or regulatory differences between these components?

A: No. Both components are ROHS3 compliant, EAR99 classified, and carry MSL rating 1 (Unlimited), ensuring equivalent regulatory and environmental handling requirements.

Q: What considerations apply when transitioning from through-hole to surface mount packaging?

A: Surface mount assembly requires compatible manufacturing equipment, modified PCB layout with appropriate pad dimensions for 28-TSSOP package, and updated assembly process parameters. Verify supplier device package specifications match your assembly capabilities.
