Substitute Part Grouping Explanation

Substitution eligibility for the RES1K5 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1.5k Ohm
• Tolerance: ±10%
• Power rating: 12.5W
• Taper characteristic: Linear
• Number of turns: 1
• Rotation angle: 300°
• Resistive material: Wirewound
• Termination: Solder Lug
• Mounting configuration: Panel Mount
• Physical dimensions: Round body 0.875" diameter
• Bushing thread specification: 1/4-32

The RES1K5E qualifies as a direct substitute based on identical electrical and mechanical specifications across all listed parameters.

Parameter Comparison

Engineering Selection Recommendations

Both RES1K5 and RES1K5E are Active status components manufactured by Ohmite with identical electrical and mechanical specifications. The primary distinction is regulatory compliance: RES1K5E carries ROHS3 compliance certification, while RES1K5 is RoHS non-compliant. Selection between these parts should be based on application compliance requirements. Both components maintain REACH Unaffected status and EAR99 export classification. Inventory availability differs between variants, with RES1K5 currently stocked at 906 units and RES1K5E at 681 units.

Frequently Asked Questions (FAQ)

Q: Can RES1K5E replace RES1K5 in existing designs? A: Yes. RES1K5E is electrically and mechanically equivalent to RES1K5 across all specified parameters including resistance, power rating, taper, termination, and mounting configuration.

Q: What is the difference between RES1K5 and RES1K5E? A: The primary difference is RoHS compliance status. RES1K5E is ROHS3 compliant, while RES1K5 is RoHS non-compliant. All electrical and mechanical characteristics are identical.

Q: Are the physical dimensions identical? A: Yes. Both parts feature identical round body dimensions of 0.875" diameter and identical 1/4-32 bushing thread specifications for panel mount installation.

Q: Which part should be selected for new designs? A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, RES1K5E is the appropriate choice. For applications without RoHS requirements, either part is functionally equivalent.

Q: Are both parts currently available? A: Yes. RES1K5 has 906 units in stock and RES1K5E has 681 units in stock, both listed as New Original inventory.
