Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Resistance value: 124 kOhms (exact match required)
Tolerance: ±0.1% (exact match required)
Package / Case: 0805 (2012 Metric) (exact match required)
Composition: Thin Film (exact match required)
Operating Temperature Range: -55°C ~ 155°C (minimum requirement)
RoHS Status: ROHS3 Compliant (minimum requirement)
Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)

Substitute parts are grouped into two categories:

Upgrade Category (Same Power Rating): Parts with identical or improved temperature coefficient performance while maintaining 0.125W power rating.

Direct Category (Higher Power Rating): Parts with increased power dissipation capability (0.25W) while maintaining all other core electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07124KL be used as a direct replacement for RT0805BRE07124KL?

A: Yes. Both parts share identical resistance, tolerance, power rating, and package specifications. RT0805BRD07124KL offers improved temperature coefficient (±25ppm/°C vs. ±50ppm/°C) with no design changes required.

Q: Is 2176094-4 compatible with the same PCB footprint?

A: The footprint is compatible. However, seated height increases from 0.024" to 0.026" (0.60mm to 0.65mm). Verify clearance in your specific assembly before substitution.

Q: What is the advantage of RG2012N-1243-B-T5 over other substitutes?

A: RG2012N-1243-B-T5 provides the tightest temperature coefficient (±10ppm/°C), anti-sulfur protection, automotive AEC-Q200 qualification, and the lowest seated height (0.020"). Select this part for precision-critical and harsh-environment applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, matching the original RT0805BRE07124KL specifications.

Q: Which substitute offers the best inventory availability?

A: RG2012P-1243-B-T5 (Susumu) has the highest inventory at 59,946 pcs. This part combines automotive AEC-Q200 qualification with anti-sulfur protection and is suitable for high-volume production requirements.

Q: Can I use a substitute with higher power rating in a circuit designed for 0.125W?

A: Yes. A higher power-rated component (such as 2176094-4 at 0.25W) is electrically compatible and provides additional thermal margin. Verify PCB layout accommodates the slightly increased height.
