Substitute Part Grouping Explanation

Substitution eligibility for the 20J27RE is determined by strict equivalence across the following critical parameters:

• Resistance value: 27 Ohms
• Tolerance: ±5%
• Power rating: 10W
• Composition: Wirewound
• Package: Axial
• Physical dimensions: 0.394" Dia x 1.858" L (10.00mm x 47.20mm)
• Temperature coefficient: ±30ppm/°C
• Features: Flame retardant coating and safety characteristics

The identified substitute, Ohmite 20J27R, maintains identical electrical specifications and mechanical form factor, confirming direct substitutability within the same product series.

Parameter Comparison

Engineering Selection Recommendations

Both the 20J27RE and 20J27R are active production parts from Ohmite's Series 20 wirewound resistor line. The primary distinction is regulatory compliance: the 20J27RE meets ROHS3 requirements, while the 20J27R is RoHS non-compliant. Selection between these parts should be based on application regulatory requirements. For applications subject to RoHS3 compliance mandates, the 20J27RE is the appropriate choice. For applications without RoHS3 requirements, the 20J27R provides an equivalent alternative with comparable inventory availability. Both parts share identical electrical performance, mechanical dimensions, and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 20J27R be used as a direct replacement for the 20J27RE?

A: Yes, from an electrical and mechanical standpoint. Both parts are 27 Ohm, 10W, ±5% tolerance wirewound resistors in identical axial packages with matching dimensions and thermal coefficients. The substitution is valid for applications where RoHS3 compliance is not a requirement.

Q: What is the key difference between these two parts?

A: The 20J27RE is ROHS3 compliant, while the 20J27R is RoHS non-compliant. All other specifications—resistance, power rating, tolerance, composition, package type, and physical dimensions—are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.394" diameter by 1.858" length (10.00mm x 47.20mm), ensuring identical PCB footprint and mounting compatibility.

Q: Do these parts have the same temperature coefficient?

A: Yes. Both the 20J27RE and 20J27R have a temperature coefficient of ±30ppm/°C, providing equivalent thermal stability across operating conditions.

Q: Which part should I specify for a new design?

A: If your application or market requires RoHS3 compliance, specify the 20J27RE. If RoHS compliance is not a constraint, either part is electrically and mechanically equivalent.
