RT0402DRD07487RL Equivalent & Substitute Parts

Part Overview

The RT0402DRD07487RL is a 487 Ohm ±0.5% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This component is rated for 0.063W (1/16W) power dissipation with an operating temperature range of -55°C to 155°C. The part is ROHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating, indicating suitability for standard PCB assembly and storage conditions.

Substitute parts are identified based on matching electrical specifications (resistance value, power rating, package size) and mechanical compatibility. Alternative sources provide equivalent or improved tolerance grades while maintaining identical package footprint and thermal characteristics.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Matching Parameters:

Resistance value: 487 Ohms (exact match required)
Package / Case: 0402 (1005 Metric) (exact match required)
Power rating: 0.063W minimum (equal or greater acceptable)
Composition: Thin Film (maintains electrical performance characteristics)

Secondary Compatibility Parameters:

Operating temperature range: -55°C ~ 155°C minimum (equal or wider range acceptable)
RoHS compliance: ROHS3 Compliant (regulatory requirement)
MSL rating: Level 1 or equivalent (storage and handling compatibility)

Tolerance Consideration: The main part specifies ±0.5% tolerance. Substitute parts with ±0.1% tolerance provide improved accuracy and are directly substitutable without circuit redesign, as tighter tolerance is a functional upgrade.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD07487RL directly replace RT0402DRD07487RL?

A: Yes. Both parts share identical resistance (487 Ω), power rating (0.063W), package (0402), and operating temperature range (-55°C ~ 155°C). The substitute offers improved ±0.1% tolerance versus ±0.5%, representing a functional upgrade with no circuit redesign required.

Q: What is the significance of the ±0.1% tolerance upgrade?

A: Tighter tolerance reduces resistor value variation across production batches and temperature extremes. This improves circuit accuracy and predictability, particularly in precision analog circuits, measurement applications, and feedback networks where resistor accuracy directly affects system performance.

Q: Is ERA-2AEB4870X suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification indicates automotive-grade reliability and testing. These parts exceed standard industrial requirements and are fully compatible with general-purpose applications. The higher qualification standard does not restrict use in non-automotive designs.

Q: How does temperature coefficient affect part selection?

A: Temperature coefficient (ppm/°C) specifies resistor value drift per degree Celsius change. RN73C1E487RBTDF at ±10ppm/°C provides superior stability compared to ±25ppm/°C alternatives. Selection depends on application temperature range and circuit sensitivity to resistance variation.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging, maintaining compatibility with automated PCB assembly equipment and standard component handling procedures.

Q: What does MSL Level 1 mean for component storage?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture bake-out requirements. These components can be stored under standard warehouse conditions without special humidity control or pre-reflow baking procedures.
