Substitute Part Grouping Explanation

Substitution of the RT0805FRE0723R2L is permissible with parts meeting the following criteria:

• Identical resistance value: 23.2 Ohms
• Identical package format: 0805 (2012 Metric)
• Identical composition: Thin Film
• Identical operating temperature range: -55°C ~ 155°C
• Identical termination count: 2
• Identical physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Tolerance equal to or tighter than ±1%
• Power rating equal to or greater than 0.125W
• Compliance with ROHS3 and REACH requirements

The substitute part 6-1625868-2 (TE Connectivity Passive Product, RP73P series) satisfies all substitution criteria. This part offers enhanced specifications including tighter tolerance (±0.1% versus ±1%) and higher power rating (0.25W versus 0.125W), while maintaining identical resistance, package, and operating parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0805FRE0723R2L and 6-1625868-2 are active production components with full ROHS3 compliance and REACH unaffected status, suitable for applications requiring regulatory compliance in consumer, industrial, and automotive markets.

The RT0805FRE0723R2L remains the primary choice for applications with standard tolerance requirements (±1%) and baseline power dissipation needs (0.125W).

The 6-1625868-2 substitute provides enhanced performance characteristics: tighter tolerance (±0.1%) reduces circuit calibration drift, lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) improves temperature stability, and higher power rating (0.25W) provides additional thermal margin. The maximum seated height difference (0.026" versus 0.024") is negligible for standard PCB assembly processes. This substitute is appropriate for precision measurement circuits, high-reliability applications, or designs requiring improved thermal performance.

Frequently Asked Questions (FAQ)

Q: Can 6-1625868-2 be used as a direct replacement for RT0805FRE0723R2L in existing designs?

A: Yes. Both components share identical resistance value, package format, physical dimensions, and operating temperature range. The substitute offers superior tolerance and power rating specifications, making it functionally compatible for direct PCB substitution without design modification.

Q: What is the significance of the tolerance difference (±1% versus ±0.1%)?

A: Tolerance defines the maximum deviation from the nominal 23.2 Ohm value. The RT0805FRE0723R2L permits ±0.232 Ohm variation, while 6-1625868-2 permits ±0.0232 Ohm variation. Tighter tolerance reduces circuit performance variation and minimizes calibration requirements in precision applications.

Q: Does the 0.002" (0.05mm) height difference affect PCB assembly?

A: No. Both components fall within standard 0805 package specifications. The height difference is within typical PCB assembly tolerances and does not affect reflow soldering, component placement, or clearance requirements.

Q: Why is the temperature coefficient lower in the substitute part?

A: Temperature coefficient measures resistance change per degree Celsius. The 6-1625868-2 exhibits ±25ppm/°C versus ±50ppm/°C for the RT0805FRE0723R2L. Lower temperature coefficient indicates improved resistance stability across the -55°C to 155°C operating range, beneficial for temperature-sensitive analog circuits.

Q: Are both parts suitable for high-reliability applications?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, indicating suitability for standard manufacturing and storage conditions without special handling requirements.

Q: What is the practical difference in power dissipation capability?

A: The RT0805FRE0723R2L is rated for 0.125W continuous dissipation, while 6-1625868-2 is rated for 0.25W. In applications where resistor power dissipation approaches or exceeds 0.125W, the substitute provides additional thermal margin and reduced junction temperature rise.
