RT0805FRE0728R7L Equivalent & Substitute Parts

Part Overview

The RT0805FRE0728R7L is a 28.7 Ohm ±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 with an operating temperature range of -55°C to 155°C. The part maintains Active product status and is RoHS3 compliant with MSL Level 1 (Unlimited moisture sensitivity). Finding equivalent or substitute parts may be necessary due to inventory constraints, supply chain considerations, or specific application requirements for enhanced performance characteristics such as improved tolerance or power rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0728R7L is determined by the following critical parameters:

• Resistance value: Must be 28.7 Ohms
• Package format: Must be 0805 (2012 Metric)
• Composition: Must be thin film
• Operating temperature range: Must support -55°C to 155°C minimum
• Physical dimensions: Must be compatible with 0805 footprint specifications

The substitute part 7-1625868-1 (TE Connectivity Passive Product) meets these core substitution criteria. While this substitute offers enhanced specifications in tolerance (±0.1% versus ±1%) and power rating (0.25W versus 0.125W), it maintains the same resistance value, package format, and thin film composition. The improved temperature coefficient (±25ppm/°C versus ±50ppm/°C) provides superior stability characteristics.

Parameter Comparison

Engineering Selection Recommendations

The RT0805FRE0728R7L remains the primary specification for applications requiring RoHS3 compliance. The substitute part 7-1625868-1 is electrically compatible and physically interchangeable within the 0805 footprint, offering superior tolerance and power dissipation characteristics. However, the substitute part carries RoHS non-compliant status, which may restrict its use in regulated applications or markets with mandatory RoHS requirements. Selection between these parts should be based on compliance obligations and application-specific performance requirements rather than functional interchangeability alone.

Frequently Asked Questions (FAQ)

Q: Can 7-1625868-1 be used as a direct replacement for RT0805FRE0728R7L?

A: Yes, from an electrical and mechanical standpoint. Both components share identical resistance values (28.7 Ohms), package format (0805), and thin film composition. Physical dimensions are compatible with standard 0805 PCB footprints. The primary consideration is RoHS compliance status, which differs between the two parts.

Q: What are the key differences between these two 28.7 Ohm resistors?

A: The substitute part 7-1625868-1 provides tighter tolerance (±0.1% versus ±1%), higher power rating (0.25W versus 0.125W), and superior temperature coefficient stability (±25ppm/°C versus ±50ppm/°C). The substitute has a marginally greater seated height (0.026" versus 0.024"), which remains within standard 0805 package specifications.

Q: Are there any height clearance concerns when substituting 7-1625868-1 for RT0805FRE0728R7L?

A: The height difference is 0.002" (0.05mm), which is negligible for standard PCB assembly. Both components fall within normal 0805 package tolerances and should not create clearance issues in typical circuit board designs.

Q: Which part should be selected for RoHS-regulated applications?

A: The RT0805FRE0728R7L is RoHS3 compliant and must be used for applications subject to RoHS directives or customer requirements. The substitute part 7-1625868-1 is RoHS non-compliant and is not suitable for these applications.

Q: Do both parts support the same operating temperature range?

A: Yes. Both the RT0805FRE0728R7L and 7-1625868-1 operate across -55°C to 155°C, ensuring thermal compatibility in equivalent applications.
