Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1TF56R0U are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 56 Ohms
• Tolerance: ±1%
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 2512 (6432 Metric)
• Number of terminations: 2
• Height seated (maximum): 0.028" (0.70mm)

Compliance & Ratings (Must Match):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status
• AEC-Q200 automotive qualification

Power Rating Consideration: The main part is rated at 1W. Substitute parts rated at 1W or higher (1.5W) maintain full compatibility, as higher power ratings provide equal or superior performance in the same package footprint.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (AEC-Q200 Qualified):

CRCW251256R0FKEG, RMCF2512FT56R0, and CRCW251256R0FKEGHP are all AEC-Q200 qualified alternatives suitable for automotive applications requiring the same electrical and mechanical specifications as the ERJ-S1TF56R0U. All three maintain identical resistance, tolerance, temperature coefficient, and operating temperature range. The CRCW251256R0FKEGHP offers enhanced pulse withstanding capability with a 1.5W power rating in the same package, providing additional design margin.

Non-Automotive Alternative:

RC2512FK-0756RL from YAGEO meets all electrical and mechanical parameters but lacks AEC-Q200 automotive qualification. This part is suitable only for non-automotive applications or where automotive certification is not required.

Packaging Consideration:

The ERJ-S1TF56R0U is supplied in Tape & Reel (TR) packaging. CRCW251256R0FKEG is available in Cut Tape (CT) & Digi-Reel® packaging, which may require process adjustment depending on assembly equipment compatibility. All other substitutes are supplied in Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can CRCW251256R0FKEGHP be used as a direct replacement for ERJ-S1TF56R0U?

A: Yes. The CRCW251256R0FKEGHP maintains identical electrical specifications (56 Ohms ±1%, ±100ppm/°C, -55°C ~ 155°C) and mechanical compatibility (2512 package, 0.028" maximum height). The 1.5W power rating provides equal or superior performance compared to the 1W rating of the main part. Both are AEC-Q200 qualified.

Q: Is RC2512FK-0756RL suitable for automotive applications?

A: RC2512FK-0756RL meets all electrical and mechanical requirements but is not AEC-Q200 qualified. It is suitable only for non-automotive applications or designs where automotive certification is not a requirement.

Q: What is the difference between the packaging formats offered?

A: ERJ-S1TF56R0U and most substitutes are supplied in Tape & Reel (TR) format. CRCW251256R0FKEG is available in Cut Tape (CT) & Digi-Reel® format. Verify assembly equipment compatibility with the packaging format before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant with MSL rating of 1 (Unlimited) and REACH Unaffected status, matching the environmental compliance of the ERJ-S1TF56R0U.

Q: Can I use a substitute part with higher power rating?

A: Yes. CRCW251256R0FKEGHP is rated at 1.5W compared to the 1W rating of ERJ-S1TF56R0U. Higher power ratings in the same package provide additional thermal margin and are fully compatible with designs specified for 1W operation.
