Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B8J25R is determined by matching the following critical parameters: resistance value (25 Ohms), tolerance (±5%), power rating (8W), composition (wirewound), package type (axial), temperature coefficient (±260ppm/°C), and physical dimensions (0.313" Dia x 1.000" L). The identified substitute maintains all electrical characteristics and mechanical specifications. Packaging configuration differences are noted but do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both B8J25R and B8J25RE are functionally equivalent for circuit applications requiring 25 Ohm, 8W axial wirewound resistors. Selection between these parts should be based on compliance requirements and packaging needs. The B8J25RE offers ROHS3 compliance, making it suitable for applications subject to RoHS regulations. The B8J25R is appropriate for applications without RoHS compliance mandates. Packaging differences (standard versus bulk) do not affect electrical performance and should be selected based on procurement and assembly workflow requirements.

Frequently Asked Questions (FAQ)

Q: Are B8J25R and B8J25RE electrically interchangeable? A: Yes. Both parts share identical resistance (25 Ohms), tolerance (±5%), power rating (8W), temperature coefficient (±260ppm/°C), and composition (wirewound). They are direct electrical substitutes.

Q: What is the difference between B8J25R and B8J25RE? A: The primary differences are packaging configuration (standard versus bulk) and RoHS compliance status. B8J25RE is ROHS3 compliant, while B8J25R is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Can I use B8J25RE in place of B8J25R in my design? A: Yes, provided your application does not have specific packaging requirements tied to the standard packaging format. If RoHS compliance is required, B8J25RE is the appropriate choice.

Q: Are the physical dimensions identical? A: Yes. Both parts measure 0.313" Dia x 1.000" L (7.94mm x 25.40mm) and use axial package configuration with 2 terminations.

Q: Which part should I select for new designs? A: For new designs subject to RoHS regulations, select B8J25RE. For applications without RoHS mandates, either part is acceptable based on packaging and inventory availability.
