Substitute Part Grouping Explanation

Substitution for the AT0805DRD0728RL is determined by the following criteria:

• Resistance value must be 28 Ohms
• Package must be 0805 (2012 Metric) for mechanical and electrical compatibility
• Composition must be thin film to maintain performance characteristics
• Temperature coefficient must be ±25ppm/°C
• Operating temperature range must be -55°C ~ 155°C
• RoHS3 compliance required
• Moisture Sensitivity Level must be 1 (Unlimited)

The substitute part 7-1625868-0 meets all these criteria. While it features improved tolerance (±0.1% versus ±0.5%) and higher power rating (0.25W versus 0.125W), these represent enhanced specifications that maintain full compatibility with the original part's electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the AT0805DRD0728RL and 7-1625868-0 are active production parts with ROHS3 compliance and unlimited moisture sensitivity rating. The substitute part 7-1625868-0 provides tighter tolerance specification (±0.1% versus ±0.5%) and higher power dissipation capability (0.25W versus 0.125W) while maintaining identical mechanical footprint and thermal characteristics. Selection between these parts depends on circuit requirements for tolerance and power handling. The AT0805DRD0728RL includes automotive AEC-Q200 qualification and anti-sulfur coating; verify application requirements for these specific features when considering substitution.

Frequently Asked Questions (FAQ)

Q: Can 7-1625868-0 be used as a direct replacement for AT0805DRD0728RL?

A: Yes. Both parts share identical resistance value, package, composition, temperature coefficient, and operating temperature range. The substitute has improved tolerance and higher power rating, which are compatible with the original part's specifications.

Q: Are the physical dimensions identical?

A: The length and width are identical (0.079" x 0.049" / 2.00mm x 1.25mm). Maximum seated height differs slightly: 0.024" (0.60mm) for AT0805DRD0728RL versus 0.026" (0.65mm) for 7-1625868-0. This 0.002" difference is within standard PCB assembly tolerances.

Q: What is the difference in tolerance specification?

A: AT0805DRD0728RL has ±0.5% tolerance while 7-1625868-0 has ±0.1% tolerance. The substitute provides tighter tolerance, which may improve circuit performance in applications sensitive to resistance variation.

Q: Does the substitute part have automotive qualification?

A: The AT0805DRD0728RL carries AEC-Q200 automotive qualification and anti-sulfur coating. The 7-1625868-0 specification does not list these features. Confirm automotive requirements before substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both AT0805DRD0728RL and 7-1625868-0 are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).
