Key Parameters

Substitute Part Grouping Explanation

The 30J27RE qualifies as a direct substitute for the 30J27R based on the following critical parameters:

• Identical resistance value: 27 Ohms
• Matching tolerance: ±5%
• Equivalent power rating: 10W
• Same composition: Wirewound
• Identical package form factor: Axial
• Matching physical dimensions: 0.406" Dia x 1.843" L (10.30mm x 46.80mm)
• Same number of terminations: 2
• Same manufacturer series: High Energy Wirewound

The primary difference between these parts is packaging configuration and RoHS compliance status, which do not affect electrical or mechanical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 30J27R and 30J27RE are active production components from Ohmite's High Energy Wirewound series. Selection between these parts should be based on the following criteria:

30J27R is appropriate for applications where RoHS non-compliant components are acceptable and standard packaging is preferred.

30J27RE is the preferred selection for applications requiring ROHS3 compliance. This part maintains identical electrical and mechanical specifications while meeting current environmental and regulatory standards. The bulk packaging option provides flexibility for high-volume procurement scenarios.

Both parts carry identical REACH Unaffected and EAR99 ECCN classifications, ensuring equivalent regulatory treatment in export and supply chain contexts.

Frequently Asked Questions (FAQ)

Q: Can 30J27RE be used as a direct replacement for 30J27R in existing designs?

A: Yes. The 30J27RE is electrically and mechanically identical to the 30J27R. Both components have the same 27 Ohm resistance, ±5% tolerance, 10W power rating, wirewound composition, and axial package form factor with matching physical dimensions. The parts are interchangeable at the circuit level.

Q: What is the difference between the 30J27R and 30J27RE?

A: The primary differences are packaging configuration and RoHS compliance status. The 30J27R uses standard packaging and is RoHS non-compliant, while the 30J27RE is supplied in bulk packaging and meets ROHS3 compliance requirements. All electrical and mechanical parameters are identical.

Q: Does the bulk packaging of 30J27RE affect component performance?

A: No. Packaging configuration does not impact electrical performance or mechanical compatibility. Bulk packaging refers only to the quantity and presentation method of components during shipment and storage, not to the component itself.

Q: Are there any thermal or environmental performance differences between these parts?

A: No. Both parts are from the same High Energy Wirewound series and share identical power ratings, composition, and physical specifications. Environmental performance characteristics are equivalent.

Q: Which part should be selected for new designs?

A: For new designs, the 30J27RE is recommended due to ROHS3 compliance alignment with current regulatory standards and environmental requirements. The identical electrical and mechanical specifications ensure no design modifications are necessary.
