Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the B8J150 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

• Resistance value: 150 Ohms
• Tolerance: ±5%
• Power rating: 8W
• Composition: Wirewound
• Package configuration: Axial through-hole
• Physical dimensions: 0.313" Dia x 1.000" L (7.94mm x 25.40mm)
• Temperature coefficient: ±260ppm/°C
• Safety features: Flame retardant coating

The B8J150E is classified as a parametric equivalent, sharing identical electrical performance and mechanical form factor. The primary distinction is packaging format (Box versus Bulk) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the B8J150 and B8J150E are active production components from Ohmite's Brown Devil® 200 series, with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

B8J150 (Box Packaging): Select this part when RoHS non-compliant components are acceptable for the application and box packaging is preferred for inventory management or traceability requirements.

B8J150E (Bulk Packaging): Select this part when ROHS3 compliance is required for the end application or when bulk packaging aligns with manufacturing processes. This variant provides equivalent performance with enhanced regulatory compliance.

Both parts are suitable for direct substitution in through-hole axial resistor applications requiring 8W power dissipation at 150 Ohms with ±5% tolerance and flame retardant safety features.

Frequently Asked Questions (FAQ)

Q: Are B8J150 and B8J150E electrically identical? A: Yes. Both parts have identical resistance (150 Ohms), tolerance (±5%), power rating (8W), temperature coefficient (±260ppm/°C), and composition (wirewound with flame retardant coating).

Q: What is the difference between B8J150 and B8J150E? A: The primary differences are packaging format (Box versus Bulk) and RoHS compliance status. B8J150 is RoHS non-compliant, while B8J150E is ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Can B8J150E replace B8J150 in existing designs? A: Yes. The B8J150E is a direct parametric equivalent with identical physical dimensions (0.313" Dia x 1.000" L), axial package configuration, and all electrical characteristics. No design modifications are required.

Q: Does packaging format affect component performance? A: No. Box and Bulk packaging formats do not affect electrical performance or mechanical compatibility. The difference is in quantity per package and handling format.

Q: Which part should I select for RoHS-compliant applications? A: Select the B8J150E, which carries ROHS3 compliance certification. The B8J150 is RoHS non-compliant and should not be used in applications requiring RoHS compliance.

Q: Are both parts available in the same quantities? A: Inventory levels differ. B8J150 has 972 units in stock, while B8J150E has 703 units in stock. Verify current availability with your supplier for production requirements.
