Key Parameters

Substitute Part Grouping Explanation

Substitution of the WR12X433 JTL is determined by strict equivalence across the following critical parameters:

• Resistance Value: 43 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 0.25W / 1/4W (exact match required)
• Package Type: 1206 (3216 Metric) surface mount (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Compliance: RoHS3 compliant, REACH unaffected (exact match required)

The substitute part CR08433J from Meritek meets all critical electrical and mechanical parameters, enabling direct substitution in applications requiring the WR12X433 JTL specification.

Parameter Comparison

Engineering Selection Recommendations

The CR08433J from Meritek is a direct electrical and functional equivalent to the WR12X433 JTL. Both components share identical resistance, tolerance, power rating, package designation, and thermal characteristics. Both parts maintain Active product status and full RoHS3 compliance with REACH unaffected designation.

Physical dimensions show minor variations within acceptable tolerances for 1206 package specifications. The CR08433J exhibits a maximum seated height of 0.024" (0.60mm) compared to 0.030" (0.75mm) for the WR12X433 JTL, and a length of 0.126" (3.20mm) versus 0.122" (3.10mm). These dimensional differences remain within standard 1206 package tolerances and do not affect PCB assembly compatibility or electrical performance.

Selection between these parts may be based on availability, lead time, supplier preference, or inventory management requirements, as both components satisfy identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)
