SN10503DR Equivalent & Substitute Parts Reference

Part Overview

The SN10503DR is a voltage feedback operational amplifier manufactured by Texas Instruments, designed for video amplification applications. This device integrates three independent amplifier circuits in a 14-SOIC surface mount package with rail-to-rail output capability. The SN10503DR is classified as an obsolete product, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. Substitute parts must maintain identical electrical performance characteristics and compatible packaging specifications to ensure direct replacement capability in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN10503DR is determined by strict equivalence across the following critical parameters:

Electrical Performance Criteria:

• Number of circuits: 3 independent amplifier channels
• Bandwidth: 170 MHz (-3dB)
• Slew rate: 900 V/µs
• Supply current: 14 mA
• Output current per channel: 100 mA
• Supply voltage range: 2.7V ~ 16V (single), ±1.35V ~ 8V (dual)
• Output configuration: Rail-to-rail

Mechanical & Compliance Criteria:

• Mounting type: Surface mount
• Base product number: SN105 series
• RoHS3 compliance
• REACH unaffected status
• ECCN: EAR99 classification

The SN10503PWP qualifies as a manufacturer-recommended substitute based on identical electrical specifications and compliance certifications. The primary distinction is packaging format: the substitute uses 14-PowerTSSOP (0.173", 4.40mm Width) versus the original 14-SOIC (0.154", 3.90mm Width) package.

Parameter Comparison

Engineering Selection Recommendations

The SN10503PWP is the manufacturer-designated substitute for the obsolete SN10503DR. Both devices maintain identical electrical specifications and are manufactured by Texas Instruments under the SN105 base product series.

Compliance Status: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Product Lifecycle Consideration: The SN10503DR is classified as obsolete, while the SN10503PWP maintains active product status. Selection of the SN10503PWP ensures long-term availability and supply chain continuity.

Packaging Consideration: The substitute employs a 14-PowerTSSOP package (0.173" width) compared to the original 14-SOIC package (0.154" width). PCB layout modifications may be required to accommodate the increased package width. Pinout compatibility must be verified against the specific circuit board design.

Moisture Sensitivity: The SN10503PWP carries MSL 2 (1 Year) rating versus MSL 1 (Unlimited) for the original part. This affects storage and handling protocols but does not impact electrical performance in operational environments.

Frequently Asked Questions (FAQ)

Q: Can the SN10503PWP directly replace the SN10503DR without circuit modifications?

A: Electrical substitution is direct due to identical performance specifications. However, physical PCB layout modifications are required due to package dimension differences. The SN10503PWP (14-PowerTSSOP, 0.173" width) is wider than the SN10503DR (14-SOIC, 0.154" width). Pinout compatibility must be confirmed for your specific application.

Q: What is the significance of the different package types?

A: The SN10503DR uses 14-SOIC packaging, while the SN10503PWP uses 14-PowerTSSOP packaging. Both are surface mount packages with identical pin counts and electrical functionality. The PowerTSSOP variant offers improved thermal characteristics due to its design, but requires PCB footprint redesign.

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

A: Both parts are ROHS3 compliant and REACH unaffected. The primary difference is moisture sensitivity level: SN10503DR is MSL 1 (unlimited storage), while SN10503PWP is MSL 2 (1-year storage limit). This affects component handling and storage procedures but not electrical performance.

Q: Why is the SN10503DR classified as obsolete?

A: The SN10503DR has reached end-of-life status in Texas Instruments' product portfolio. The SN10503PWP represents the active continuation of this product line with equivalent electrical performance and improved availability.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution is based on: 3 independent circuits, 170 MHz bandwidth, 900 V/µs slew rate, 14 mA supply current, 100 mA output current per channel, 2.7V-16V single supply or ±1.35V-8V dual supply operation, and rail-to-rail output configuration.

Q: Is the SN10503PWP currently in stock?

A: According to current inventory data, the SN10503PWP has 1125 pieces available as new original stock, compared to 963 pieces for the obsolete SN10503DR.
