Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S14F12R0U are qualified based on the following criteria:

• Identical resistance value: 12 Ohms
• Matching tolerance: ±1%
• Equivalent power rating: 0.5W (1/2W)
• Same package designation: 1210 (3225 Metric)
• Identical composition: Thick Film
• Matching temperature coefficient: ±100ppm/°C
• Overlapping operating temperature range: -55°C ~ 155°C
• Equivalent compliance: ROHS3 Compliant, MSL 1

The RC1210FR-0712RL from YAGEO meets all electrical and mechanical substitution criteria. Physical dimensions vary slightly within acceptable tolerances for the 1210 package class.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S14F12R0U and RC1210FR-0712RL are active production components with ROHS3 compliance and MSL 1 ratings. The electrical specifications are identical across resistance, tolerance, power rating, temperature coefficient, and operating temperature range. Physical dimensions fall within standard 1210 package tolerances. Selection between these parts should be based on availability, lead time, and procurement requirements. The ERJ-S14F12R0U includes automotive AEC-Q200 qualification and anti-sulfur protection; the RC1210FR-0712RL features moisture-resistant construction. Application requirements determine which feature set is appropriate.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-0712RL replace ERJ-S14F12R0U in automotive applications?

A: Both parts meet the same electrical specifications and operating temperature range. The ERJ-S14F12R0U carries AEC-Q200 automotive qualification; the RC1210FR-0712RL does not. Application requirements determine suitability.

Q: Are the physical dimension differences significant?

A: Dimensions vary within standard 1210 package tolerances. The RC1210FR-0712RL is slightly smaller in length (3.10mm vs 3.20mm) and height (0.60mm vs 0.70mm) but wider (2.60mm vs 2.50mm). These variations are within acceptable PCB footprint specifications for the 1210 package class.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur protection (ERJ-S14F12R0U) protects against sulfur-containing atmospheric corrosion. Moisture-resistant construction (RC1210FR-0712RL) provides protection against moisture ingress. These are distinct protective mechanisms addressing different environmental conditions.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the ERJ-S14F12R0U and RC1210FR-0712RL are ROHS3 compliant with REACH Unaffected status.
