Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE07158RL is determined by the following mandatory parameters:

• Resistance value: 158 Ohms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C to 155°C minimum (equal or wider range acceptable)
• RoHS compliance: ROHS3 Compliant (equal or better compliance acceptable)
• MSL rating: 1 (Unlimited) or better (equal or better rating acceptable)

Substitute parts may exceed the original tolerance specification (±1%) and power rating (0.125W) without compromising circuit functionality, provided the resistance value and package remain identical. Temperature coefficient improvements and automotive qualification certifications represent enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical compatibility with the RT0805FRE07158RL within the specified 0805 package footprint.

The 4-2176091-3 (TE Connectivity) offers improved tolerance specification (±0.1% versus ±1%) and increased power rating (0.25W versus 0.125W) with reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C). This part is suitable for applications requiring tighter resistance tolerances or higher thermal dissipation margins.

The ERA-6AEB1580V (Panasonic) provides improved tolerance (±0.1%) and reduced temperature coefficient (±25ppm/°C) while maintaining the original 0.125W power rating and 0.024" maximum seated height. This part carries AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications. REACH compliance status is vendor-defined for this part.

Frequently Asked Questions (FAQ)

Q: Can the 4-2176091-3 be used as a direct replacement for RT0805FRE07158RL?

A: Yes. Both parts share identical resistance value (158 Ohms), package type (0805), and composition (thin film). The 4-2176091-3 features superior tolerance (±0.1%) and higher power rating (0.25W), making it functionally compatible. The maximum seated height difference (0.026" versus 0.024") is within typical PCB assembly tolerances.

Q: What is the advantage of ERA-6AEB1580V over the original RT0805FRE07158RL?

A: The ERA-6AEB1580V provides improved tolerance (±0.1% versus ±1%), lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), and AEC-Q200 automotive qualification. It maintains the original power rating (0.125W) and seated height (0.024"), ensuring direct mechanical compatibility.

Q: Are there any height restrictions when substituting with 4-2176091-3?

A: The 4-2176091-3 has a maximum seated height of 0.026" compared to 0.024" for the original part. This 0.002" (0.05mm) difference is negligible for most applications but should be verified if PCB clearance is constrained.

Q: Which substitute part is recommended for automotive applications?

A: The ERA-6AEB1580V carries AEC-Q200 automotive qualification and is the appropriate choice for automotive and high-reliability applications requiring certified component qualification.

Q: Do all three parts have identical moisture sensitivity ratings?

A: Yes. All three parts carry MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements during storage or assembly.
