Substitute Part Grouping Explanation

Substitute parts for the Ohmite 91J6R2 are identified based on strict parametric equivalence. The following electrical and mechanical parameters must match for direct substitution:

• Resistance Value: 6.2 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 1.5W (exact match required)
• Composition: Wirewound (exact match required)
• Package Type: Axial (exact match required)
• Size / Dimension: 0.142" Dia x 0.453" L (3.60mm x 11.50mm) (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Number of Terminations: 2 (exact match required)

The Ohmite 91J6R2E meets all parametric equivalence criteria and qualifies as a direct substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 91J6R2 and 91J6R2E are Active status components with identical electrical and mechanical specifications. The primary differentiation is regulatory compliance:

The 91J6R2E offers ROHS3 compliance, whereas the 91J6R2 is RoHS non-compliant. For applications subject to RoHS3 regulatory requirements, the 91J6R2E is the appropriate selection. For applications without RoHS3 mandates, either part is electrically and mechanically equivalent. Both components are available in adequate inventory quantities.

Frequently Asked Questions (FAQ)

Q: Can the 91J6R2E directly replace the 91J6R2 in existing designs?

A: Yes. The 91J6R2E is parametrically equivalent to the 91J6R2 across all electrical and mechanical specifications, including resistance value, tolerance, power rating, composition, package type, and physical dimensions. Direct substitution is supported without circuit redesign.

Q: What is the difference between the 91J6R2 and 91J6R2E?

A: The primary differences are packaging format (standard vs. bulk) and regulatory compliance. The 91J6R2E is ROHS3 compliant, while the 91J6R2 is RoHS non-compliant. All electrical and mechanical parameters are identical.

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

A: No. Both parts share identical temperature coefficient (±100ppm/°C), power rating (1.5W), and thermal characteristics. Performance in thermal applications is equivalent.

Q: Which part should be selected for new designs?

A: For new designs subject to RoHS3 regulatory requirements, select the 91J6R2E. For applications without RoHS3 mandates, either part is acceptable based on availability and procurement preference.

Q: Are both parts suitable for through-hole PCB assembly?

A: Yes. Both the 91J6R2 and 91J6R2E are axial through-hole components with identical physical dimensions (0.142" Dia x 0.453" L) and two terminations, supporting standard through-hole assembly processes.
