WR06X2152FTL Equivalent & Substitute Parts

Part Overview

The WR06X2152FTL is a 21.5 kOhms ±1% thick film chip resistor manufactured by Walsin Technology Corporation in the 0603 (1608 Metric) package format. This component is rated for 0.1W (1/10W) power dissipation and operates across the temperature range of -55°C to 155°C. The part is currently in active production status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across alternative manufacturers while preserving functional performance in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WR06X2152FTL are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Resistance value: 21.5 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package format: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

All identified substitute parts meet these parameters across different manufacturers. Dimensional variations within the 0603 package specification and differences in specific features (such as moisture resistance coating) do not affect functional substitution when all electrical parameters remain identical.

Frequently Asked Questions (FAQ)

Q: Can CR162152F replace WR06X2152FTL in existing designs?

A: Yes. CR162152F meets all electrical specifications (21.5 kOhms ±1%, 0.1W, ±100ppm/°C) and package requirements (0603 1608 Metric). The 0.002" (0.05mm) reduction in seated height does not affect circuit performance or PCB assembly compatibility.

Q: What is the difference between WR06X2152FTL and RC0603FR-0721K5L?

A: Both parts are electrically identical with matching resistance, tolerance, power rating, and temperature characteristics. RC0603FR-0721K5L includes moisture-resistant thick film construction as an additional feature. Seated height is 0.022" (0.55mm) versus 0.024" (0.60mm) for the Walsin part.

Q: Are all three parts ROHS3 compliant?

A: Yes. WR06X2152FTL, CR162152F, and RC0603FR-0721K5L are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part has the best inventory availability?

A: RC0603FR-0721K5L (YAGEO) has the highest inventory with 1,695,486 pcs in stock, followed by CR162152F (Meritek) with 110,864 pcs, and WR06X2152FTL (Walsin) with 5,176 pcs.

Q: Do these parts have different temperature coefficients?

A: No. All three parts maintain ±100ppm/°C temperature coefficient across the -55°C to 155°C operating range.

Q: Is the moisture-resistant feature of RC0603FR-0721K5L necessary for standard applications?

A: The moisture-resistant feature of RC0603FR-0721K5L provides enhanced environmental protection. For applications not requiring this additional protection, CR162152F and WR06X2152FTL are functionally equivalent alternatives.

Q: Can these parts be used interchangeably on the same PCB assembly line?

A: Yes. All three parts share identical 0603 (1608 Metric) package dimensions and electrical specifications, enabling direct substitution in pick-and-place assembly processes. Seated height variations (0.022" to 0.024") fall within standard 0603 package tolerances and do not affect assembly compatibility.
