Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0730R1L is determined by the following critical parameters:

• Resistance Value: Must be 30.1 Ohms (exact match required)
• Package Type: Must be 0805 (2012 Metric) for mechanical and electrical compatibility
• Composition: Thin film construction ensures stable performance characteristics
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Number of Terminations: Must be 2-terminal configuration
• Tolerance: May be equal to or better than ±1%
• Power Rating: May be equal to or greater than 0.125W
• Temperature Coefficient: May be equal to or better than ±50ppm/°C

The substitute part 7-1625868-3 (TE Connectivity) meets all mechanical compatibility requirements and exceeds electrical performance specifications through improved tolerance (±0.1% vs ±1%), higher power rating (0.25W vs 0.125W), and superior temperature coefficient (±25ppm/°C vs ±50ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

The RT0805FRE0730R1L is ROHS3 compliant and REACH unaffected, making it suitable for applications with environmental compliance requirements. The substitute part 7-1625868-3 is RoHS non-compliant and has undefined REACH status, which may restrict its use in regulated applications or markets with strict environmental standards.

Selection between these parts should be based on:

• Compliance Requirements: If ROHS3 compliance is mandatory, the RT0805FRE0730R1L is the required choice
• Performance Margin: If enhanced tolerance (±0.1%) or higher power dissipation capability (0.25W) provides design margin benefits, the 7-1625868-3 offers superior electrical characteristics
• Regulatory Environment: Applications subject to RoHS or REACH regulations must use the RT0805FRE0730R1L

Both parts share identical mechanical dimensions, thermal operating range, and package configuration, ensuring direct footprint compatibility in 0805 SMD layouts.

Frequently Asked Questions (FAQ)

Q: Can 7-1625868-3 be used as a direct replacement for RT0805FRE0730R1L?

A: Mechanical and electrical substitution is possible due to matching package type (0805), identical resistance value (30.1 Ohms), and compatible operating temperature range. However, compliance differences must be evaluated. The substitute part is RoHS non-compliant, which may disqualify it for regulated applications.

Q: What are the key differences between these parts?

A: The primary differences are tolerance (±0.1% vs ±1%), power rating (0.25W vs 0.125W), temperature coefficient (±25ppm/°C vs ±50ppm/°C), and regulatory compliance status. The substitute offers superior electrical performance but lacks ROHS3 certification.

Q: Are the physical dimensions identical?

A: Both parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Height differs slightly (0.026" vs 0.024"), which is within typical PCB assembly tolerances and does not affect compatibility.

Q: Which part should be selected for high-precision applications?

A: The 7-1625868-3 provides superior tolerance (±0.1%) and temperature coefficient (±25ppm/°C), making it more suitable for precision measurement and analog signal conditioning circuits where component stability is critical.

Q: Are there any soldering or assembly considerations?

A: Both parts are 0805 SMD components with identical termination configuration (2-pin). Standard SMD assembly processes and reflow profiles apply to both parts without modification.
