Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF73R2U is determined by strict alignment of the following parameters:

• Resistance value: 73.2 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The RMCF2512FT73R2 from Stackpole Electronics Inc meets all these criteria and qualifies as a direct substitute.

Frequently Asked Questions (FAQ)

Q: Can RMCF2512FT73R2 be used as a direct replacement for ERJ-S1TF73R2U?

A: Yes. Both parts share identical resistance (73.2 Ohms), tolerance (±1%), power rating (1W), package (2512), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. Physical dimensions are within acceptable tolerance (Panasonic: 6.40mm x 3.20mm; Stackpole: 6.30mm x 3.20mm).

Q: Are there any differences in the anti-sulfur or protective features?

A: The ERJ-S1TF73R2U specifies anti-sulfur protection. The RMCF2512FT73R2 specification does not explicitly list this feature in the provided data. This difference should be evaluated against application requirements.

Q: Do both parts meet automotive standards?

A: Yes. Both components carry AEC-Q200 qualification and are suitable for automotive applications within the specified operating temperature range of -55°C to 155°C.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are these parts RoHS compliant?

A: Yes. Both ERJ-S1TF73R2U and RMCF2512FT73R2 are ROHS3 compliant.
