B8J700 Equivalent & Substitute Parts

Part Overview

The B8J700 is an 8W axial wirewound resistor with 700 Ohms resistance and ±5% tolerance, manufactured by Ohmite as part of the Brown Devil® 200 series. This component is designed for through-hole applications requiring flame retardant coating and safety features. The part is currently active in production with 1001 units in stock. Substitute parts are identified when packaging configurations differ or when RoHS compliance requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The B8J700E is classified as a parametric equivalent to the B8J700. Both parts share identical electrical characteristics (700 Ohms, ±5% tolerance, 8W power rating) and mechanical specifications (axial package, 0.313" Dia x 1.000" L dimensions). The substitution is valid based on the following key parameters:

• Resistance Value: 700 Ohms (identical)
• Tolerance: ±5% (identical)
• Power Rating: 8W (identical)
• Composition: Wirewound (identical)
• Package / Case: Axial (identical)
• Size / Dimension: 0.313" Dia x 1.000" L (identical)
• Temperature Coefficient: ±260ppm/°C (identical)
• Features: Flame Retardant Coating, Safety (identical)

The primary difference between these parts is packaging configuration (Bulk for B8J700E versus standard for B8J700) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both B8J700 and B8J700E are active production parts from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements and packaging needs:

• Select B8J700 for applications where RoHS non-compliant components are acceptable and standard packaging is required.
• Select B8J700E for applications requiring ROHS3 compliance or when bulk packaging is specified.

Both parts are suitable for through-hole circuit board assembly in applications requiring 700 Ohm, 8W axial wirewound resistors with flame retardant coating and safety features.

Frequently Asked Questions (FAQ)

Q: Can B8J700E be used as a direct replacement for B8J700?

A: Yes. Both parts have identical electrical specifications (700 Ohms, ±5% tolerance, 8W), identical mechanical dimensions (0.313" Dia x 1.000" L axial package), and identical thermal characteristics (±260ppm/°C). The primary differences are RoHS compliance status and packaging configuration.

Q: What is the difference between B8J700 and B8J700E?

A: The B8J700E is ROHS3 compliant, while the B8J700 is RoHS non-compliant. Additionally, B8J700E is supplied in bulk packaging, whereas B8J700 uses standard packaging. All electrical and mechanical parameters are identical.

Q: Are these parts interchangeable in PCB assembly?

A: Yes. Both parts share the same axial package configuration, identical lead spacing, and identical physical dimensions. They are mechanically and electrically interchangeable in through-hole circuit board applications.

Q: Which part should I specify for new designs?

A: Specify B8J700E for new designs if ROHS3 compliance is required by your application or regulatory environment. Both parts are active production items with adequate inventory.

Q: Do these resistors have the same temperature coefficient?

A: Yes. Both B8J700 and B8J700E have a temperature coefficient of ±260ppm/°C, ensuring identical thermal performance across the operating range.
