RT0402DRD07105RL Equivalent & Substitute Parts

Part Overview

The RT0402DRD07105RL is a 105 Ohm ±0.5% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This surface mount device is rated at 0.063W (1/16W) power dissipation and operates across -55°C to 155°C. The part is Active status and RoHS3 compliant with MSL 1 rating, making it suitable for general industrial and commercial applications requiring precision resistive elements.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances. Alternative sources provide equivalent or enhanced specifications while maintaining the same package footprint and termination configuration.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Resistance Value: Must be 105 Ohms
Package / Case: Must be 0402 (1005 Metric)
Composition: Must be Thin Film
Temperature Coefficient: Must be ±25ppm/°C
Operating Temperature Range: Must be -55°C to 155°C
Terminations: Must be 2
RoHS Compliance: Must be RoHS3 Compliant

Tolerance and power rating variations are permitted within the substitute list when the above core parameters remain constant. Tolerance upgrades (tighter specifications) and power rating increases represent functional improvements without compromising compatibility. All substitute parts maintain identical mechanical dimensions and electrical operating characteristics within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can RNCF0402DTE105R replace RT0402DRD07105RL in any application?

A: Yes. RNCF0402DTE105R maintains identical resistance value, tolerance, package dimensions, temperature coefficient, and operating temperature range. The increased power rating (0.1W versus 0.063W) provides additional thermal capability without affecting electrical compatibility. Automotive AEC-Q200 qualification is an additional feature not present in the original part.

Q: What is the difference between the tolerance specifications in the substitute parts?

A: RT0402DRD07105RL, RNCF0402DTE105R specify ±0.5% tolerance. CPF0402B105RE1 and ERA-2AEB1050X specify ±0.1% tolerance. Tighter tolerance (±0.1%) provides improved resistive accuracy and is suitable for precision applications. Both tolerance levels are compatible with the same package and operating parameters.

Q: Are there mechanical compatibility concerns with ERA-2AEB1050X?

A: ERA-2AEB1050X has a maximum seated height of 0.016" (0.40mm) compared to 0.014" (0.35mm) for other variants. This 0.002" (0.05mm) difference must be evaluated against PCB layout constraints and component clearance requirements. Horizontal dimensions remain identical across all parts.

Q: Which substitute part is recommended for automotive applications?

A: Both RNCF0402DTE105R and ERA-2AEB1050X carry Automotive AEC-Q200 qualification. ERA-2AEB1050X additionally offers tighter tolerance specification (±0.1%). Selection depends on whether tolerance upgrade is required for the specific application.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RT0402DRD07105RL, RNCF0402DTE105R, CPF0402B105RE1, and ERA-2AEB1050X are all RoHS3 compliant. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard storage and handling procedures.
