• Resistance value: 27 Ohms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Wirewound
• Package: Axial
• Physical dimensions: 0.220" Dia x 0.516" L (5.60mm x 13.10mm)
• Temperature coefficient: ±30ppm/°C
• Terminations: 2

The substitute part 23J27RE meets all electrical and mechanical parameters required for direct substitution. Differences in packaging format (Bulk vs. standard) and compliance certifications do not affect functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The 23J27RE is a direct parametric equivalent to the 23J27R. Both parts are Active status components from Ohmite's Series 20 wirewound resistor line with identical electrical specifications and physical form factors.

Selection between these parts should be based on:

• RoHS compliance requirements: The 23J27RE is RoHS Compliant, while the 23J27R is RoHS non-compliant. Applications subject to RoHS directives must use the 23J27RE.
• Packaging format: The 23J27RE is supplied in Bulk packaging, which may affect procurement and handling procedures compared to standard packaging.
• Moisture sensitivity: The 23J27RE specifies MSL 1 (Unlimited), indicating superior moisture resistance characteristics.

Both parts maintain identical circuit performance characteristics and are suitable for through-hole PCB assembly applications requiring 27 Ohm, 3W load dissipation.

Frequently Asked Questions (FAQ)

Q: Can the 23J27RE replace the 23J27R in existing designs?

A: Yes. The 23J27RE is a parametric equivalent with identical resistance, tolerance, power rating, composition, package type, and physical dimensions. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between the 23J27R and 23J27RE?

A: The primary differences are RoHS compliance status (23J27RE is RoHS Compliant; 23J27R is non-compliant) and moisture sensitivity level (23J27RE specifies MSL 1). Electrical performance and physical form factor are identical.

Q: Does packaging format affect circuit performance?

A: No. Bulk packaging is a procurement and handling specification only. It does not affect the electrical or mechanical performance of the component in circuit applications.

Q: Are there any thermal or frequency limitations when substituting?

A: No. Both parts share identical temperature coefficient (±30ppm/°C) and are rated for the same 3W power dissipation. Thermal and frequency performance characteristics are equivalent.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory and compliance requirements. For applications requiring RoHS compliance, use the 23J27RE. For applications without RoHS requirements, either part is suitable based on availability and packaging preferences.
