Substitute Part Grouping Explanation

Substitution eligibility for the Y4485V0071BA9L is determined by strict equivalence across the following critical parameters:

• Resistance Values: Must be 1k and 10k ohm configuration
• Circuit Type: Must be voltage divider topology
• Number of Resistors: Must be 2-element network
• Number of Pins: Must be 3-terminal configuration
• Package / Case: Must be 1610 J-Lead (3 Terminals)
• Mounting Type: Must be surface mount
• Physical Dimensions: Must match 0.160" L x 0.106" W (4.06mm x 2.69mm)
• Operating Temperature Range: Must support -65°C ~ 125°C
• Power Per Element: Must be 50mW minimum

The identified substitute Y4485V0071QT9W maintains all critical electrical and mechanical parameters while offering improved tolerance specifications (±0.02% vs ±0.1%) and tighter resistor matching ratio (±0.01% vs ±0.05%). The primary difference is packaging format (Tray vs Bulk) and enhanced precision characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both Y4485V0071BA9L and Y4485V0071QT9W are active production components from VPG Foil Resistors with ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts is based on tolerance and matching requirements:

• Y4485V0071BA9L is appropriate for applications where ±0.1% tolerance and ±0.05% resistor matching ratio meet design specifications and bulk packaging is preferred.

• Y4485V0071QT9W is appropriate for applications requiring tighter tolerance control (±0.02%) and superior resistor matching (±0.01%), with tray packaging format for component handling and traceability.

Both parts are electrically and mechanically interchangeable within the 1610 J-Lead package footprint and support identical operating temperature ranges. Selection should be based on precision requirements of the voltage divider circuit and packaging logistics.

Frequently Asked Questions (FAQ)

Q: Can Y4485V0071QT9W replace Y4485V0071BA9L in existing designs?

A: Yes. Both parts share identical resistance values (1k, 10k ohm), circuit topology (voltage divider), pin configuration (3-terminal), package type (1610 J-Lead), and physical dimensions. The substitute offers improved tolerance and matching specifications, making it a direct electrical and mechanical replacement.

Q: What is the primary difference between these two parts?

A: The main differences are tolerance specification (±0.1% vs ±0.02%), resistor matching ratio (±0.05% vs ±0.01%), and packaging format (Bulk vs Tray). All other electrical and mechanical parameters are identical.

Q: Are there any PCB layout or assembly considerations when switching between these parts?

A: No. Both parts use the same 1610 J-Lead package with identical footprint dimensions (0.160" L x 0.106" W, 4.06mm x 2.69mm) and maximum seated height (0.071", 1.80mm). PCB layouts and assembly processes require no modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both Y4485V0071BA9L and Y4485V0071QT9W are ROHS3 compliant with MSL rating of 1 (Unlimited). Both are classified as EAR99 for export control purposes.

Q: Which part should be selected for high-precision voltage divider applications?

A: Y4485V0071QT9W is recommended for applications requiring tighter tolerance control and superior resistor matching. The ±0.02% tolerance and ±0.01% matching ratio provide enhanced precision for critical voltage divider circuits.

Q: Are both parts available in the same quantities?

A: Current inventory differs: Y4485V0071BA9L has 817 units in stock (Bulk packaging), while Y4485V0071QT9W has 711 units in stock (Tray packaging). Packaging format selection may influence procurement decisions based on assembly requirements.
