Engineering Selection Recommendations

Both RES2R0 and RES2R0E are active production components from Ohmite with identical electrical and mechanical specifications. The primary distinction is regulatory compliance: RES2R0E carries ROHS3 certification, while RES2R0 is RoHS non-compliant. Selection between these parts depends on application requirements and regulatory mandates. For applications requiring RoHS3 compliance, RES2R0E is the appropriate choice. Both components maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can RES2R0E replace RES2R0 in existing designs? A: Yes. RES2R0E is electrically and mechanically identical to RES2R0, with identical resistance, power rating, taper, termination, and physical dimensions. Direct substitution is functionally equivalent.

Q: What is the difference between RES2R0 and RES2R0E? A: The primary difference is RoHS compliance status. RES2R0E is ROHS3 compliant, while RES2R0 is RoHS non-compliant. All other specifications are identical.

Q: Are the panel mount dimensions identical? A: Yes. Both parts feature identical 1/4-32 bushing thread, 0.875" round body diameter, and 0.625" slotted actuator dimensions, ensuring identical panel mounting compatibility.

Q: Does RoHS compliance affect electrical performance? A: No. RoHS3 compliance in RES2R0E does not alter electrical characteristics. Resistance, power rating, tolerance, and taper remain identical to RES2R0.

Q: Can these parts be used interchangeably in solder lug applications? A: Yes. Both components use identical solder lug termination, allowing direct substitution in PCB and chassis wiring applications.
