Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF18R0U is determined by strict equivalence across the following parameters:

• Resistance value: 18 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All three substitute parts meet these core electrical and mechanical requirements. Variations in physical dimensions (length, width, height) remain within acceptable tolerances for the 2512 package standard and do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All four parts are active products with ROHS3 compliance and identical electrical specifications. Selection between the ERJ-S1TF18R0U and its substitutes should be based on:

• Inventory availability and lead time requirements
• Automotive AEC-Q200 certification requirement: The ERJ-S1TF18R0U, CRCW251218R0FKEG, and RMCF2512FT18R0 carry explicit AEC-Q200 ratings. The RC2512FK-0718RL does not list AEC-Q200 certification but features moisture-resistant construction.
• Anti-sulfur or moisture-resistant feature requirements specific to application environment
• Supply chain and procurement preferences by manufacturer

Frequently Asked Questions (FAQ)

Q: Can CRCW251218R0FKEG replace ERJ-S1TF18R0U in automotive applications? A: Yes. Both parts are AEC-Q200 rated, share identical electrical parameters (18 Ohms ±1%, 1W, ±100ppm/°C), and use the 2512 package. Physical dimensions vary slightly but remain within 2512 package tolerances.

Q: What is the difference between the anti-sulfur feature of ERJ-S1TF18R0U and the moisture-resistant feature of RC2512FK-0718RL? A: These are distinct environmental protection features. Anti-sulfur construction protects against sulfur contamination in specific industrial environments. Moisture-resistant construction protects against moisture ingress. Application requirements determine which feature is necessary.

Q: Are all substitute parts suitable for -55°C to 155°C operating range applications? A: Yes. All four parts specify -55°C ~ 155°C operating temperature range with ±100ppm/°C temperature coefficient.

Q: Does package size variation affect circuit board layout compatibility? A: Physical dimensions vary within the 2512 (6432 Metric) standard. Maximum variations are: length 0.248" to 0.252", width 0.122" to 0.126", height 0.026" to 0.028". These tolerances are standard for the 2512 package and do not affect PCB footprint compatibility.

Q: Which substitute offers the best inventory availability? A: CRCW251218R0FKEG (Vishay Dale) has 79234 pieces in stock, significantly higher than other options.

Q: Is RC2512FK-0718RL suitable for automotive applications without AEC-Q200 certification? A: RC2512FK-0718RL does not carry explicit AEC-Q200 certification. For applications requiring automotive qualification, ERJ-S1TF18R0U, CRCW251218R0FKEG, or RMCF2512FT18R0 are recommended.
