Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RL-1005-2-R510-FNH is determined by the following critical parameters:

• Resistance value: 510 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W minimum (equal or higher acceptable)
• Package: 0402 (1005 Metric) (exact match required)
• Composition: Metal Film (exact match required)
• Features: Current Sense capability (required)
• RoHS compliance: ROHS3 Compliant (required)

The KDV04FR510ET from Ohmite meets all substitution criteria. It maintains identical resistance, tolerance, power rating, package, composition, and current sense functionality while offering an active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The KDV04FR510ET is a direct functional equivalent to the RL-1005-2-R510-FNH. Both components are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for current applications. The substitute part offers superior performance characteristics: a lower temperature coefficient (±50ppm/°C versus ±100ppm/°C) and an extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C). The active product status of the KDV04FR510ET ensures long-term availability and supply chain stability, addressing the obsolescence of the original part.

Frequently Asked Questions (FAQ)

Q: Can the KDV04FR510ET be used as a direct replacement for the RL-1005-2-R510-FNH?

A: Yes. Both parts share identical electrical specifications (510 mOhms, ±1%, 0.125W) and mechanical packaging (0402/1005 Metric). The KDV04FR510ET is pin-compatible and functionally equivalent for current sense applications.

Q: What are the differences between these two parts?

A: The primary differences are product status and performance enhancements. The KDV04FR510ET is an active product with a lower temperature coefficient (±50ppm/°C versus ±100ppm/°C) and extended operating temperature range (up to 155°C versus 125°C). The RL-1005-2-R510-FNH is obsolete.

Q: Are there any packaging differences?

A: Both parts use the 0402 (1005 Metric) package. The KDV04FR510ET has a maximum seated height of 0.016" (0.40mm) compared to 0.020" (0.50mm) for the RL-1005-2-R510-FNH. This minor dimensional difference does not affect PCB assembly compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RL-1005-2-R510-FNH and KDV04FR510ET are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with the same HTSUS code (8533.21.0030).

Q: Which part should be selected for new designs?

A: The KDV04FR510ET should be selected for new designs due to its active product status, ensuring availability and supply chain continuity. Its improved temperature coefficient and extended operating range provide additional design margin for demanding applications.
