B8J1K2 Equivalent & Substitute Parts Reference

Part Overview

The B8J1K2 is a 1.2 kOhms ±5% 8W through-hole axial wirewound resistor manufactured by Ohmite as part of the Brown Devil® 200 series. This component is designed for applications requiring high power dissipation in a compact axial package with flame retardant coating and safety features. The part is currently Active in product status with 897 pieces available in new original inventory. Substitute parts are identified when packaging, compliance requirements, or inventory considerations necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B8J1K2 is determined by matching the following critical parameters:

• Resistance value: 1.2 kOhms
• Tolerance: ±5%
• Power rating: 8W
• Composition: Wirewound
• Package type: Axial
• Physical dimensions: 0.313" Dia x 1.000" L (7.94mm x 25.40mm)
• Temperature coefficient: ±260ppm/°C
• Features: Flame Retardant Coating, Safety
• Terminations: 2

The B8J1K2E qualifies as a direct substitute based on identical electrical characteristics and mechanical specifications. The primary difference is packaging format (Bulk versus standard packaging) and RoHS compliance status, which may influence selection based on procurement and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Both B8J1K2 and B8J1K2E are Active products from Ohmite's Brown Devil® 200 series with identical electrical and mechanical specifications. Selection between these parts is based on regulatory and procurement requirements:

The B8J1K2 is suitable for applications where RoHS non-compliant components are acceptable and standard packaging is required.

The B8J1K2E is the appropriate choice for applications requiring ROHS3 compliance or when bulk packaging format is preferred for manufacturing operations.

Both parts maintain identical performance characteristics in circuit applications due to matching resistance, tolerance, power rating, temperature coefficient, and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can B8J1K2E be used as a direct replacement for B8J1K2?

A: Yes. Both parts have identical electrical specifications (1.2 kOhms ±5% at 8W), composition (wirewound), temperature coefficient (±260ppm/°C), and physical dimensions (0.313" Dia x 1.000" L). The primary differences are packaging format and RoHS compliance status, which do not affect circuit performance.

Q: What is the difference between the packaging formats?

A: B8J1K2 uses standard packaging, while B8J1K2E is supplied in bulk packaging. Both formats contain the same component with identical specifications.

Q: Does RoHS compliance affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical or thermal performance. Both parts deliver identical functional characteristics in circuit applications.

Q: Are the physical dimensions identical?

A: Yes. Both B8J1K2 and B8J1K2E measure 0.313" diameter by 1.000" length (7.94mm x 25.40mm) and use axial termination configuration with 2 connection points.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements and procurement preferences. For applications requiring ROHS3 compliance, specify B8J1K2E. For applications without RoHS requirements, either part is suitable based on packaging availability and inventory considerations.
