RT0805FRE0731R6L Equivalent & Substitute Parts

Part Overview

The RT0805FRE0731R6L is a 31.6 Ohms ±1% thin film chip resistor manufactured by YAGEO in the 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or specific application performance needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0731R6L is determined by the following critical parameters:

• Resistance Value: Must be 31.6 Ohms (exact match required)
• Package Format: Must be 0805 (2012 Metric) for mechanical and electrical compatibility
• Composition: Thin film construction maintains performance characteristics
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Compliance Standards: ROHS3 compliance required for regulatory alignment

The substitute part 7-1625868-5 (TE Connectivity Passive Product) meets all critical substitution criteria. While this part offers enhanced specifications in tolerance (±0.1% vs ±1%) and power rating (0.25W vs 0.125W), it maintains identical resistance value, package format, and operating temperature range, making it a valid direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The 7-1625868-5 from TE Connectivity Passive Product is a valid substitute for the RT0805FRE0731R6L. Both components maintain Active product status and full ROHS3 compliance. The substitute part provides enhanced performance specifications across tolerance, power rating, and temperature coefficient, while maintaining identical mechanical footprint and operating temperature range. Selection between these parts should be based on inventory availability, lead time requirements, and application-specific performance margins.

Frequently Asked Questions (FAQ)

Q: Can the 7-1625868-5 be used as a direct replacement for the RT0805FRE0731R6L?

A: Yes. Both parts share identical resistance value (31.6 Ohms), package format (0805), composition (thin film), and operating temperature range (-55°C to 155°C). The substitute part meets or exceeds all critical electrical and mechanical parameters.

Q: What are the key differences between these two parts?

A: The primary differences are tolerance (±0.1% vs ±1%), power rating (0.25W vs 0.125W), and temperature coefficient (±25ppm/°C vs ±50ppm/°C). The substitute part offers superior specifications in all three areas.

Q: Are there any package or footprint concerns when substituting?

A: No. Both components use the identical 0805 (2012 Metric) package format with matching physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). PCB layout and assembly processes require no modification.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance requirements are equivalent.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements and supply chain factors. The substitute part (7-1625868-5) offers enhanced performance specifications and may be preferred for applications requiring tighter tolerance or higher power dissipation margins. The original part (RT0805FRE0731R6L) remains suitable for applications within its specified performance envelope.
