Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K3571FTP is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 3.57 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: MSL 1

All substitute parts listed meet these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within the 1206 package specification, packaging format (Tape & Reel vs. Cut Tape), and optional certifications (AEC-Q200) do not disqualify substitution but may influence selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

RC1206FR-073K57L (YAGEO) and RMCF1206FT3K57 (Stackpole Electronics Inc) are preferred substitutes. Both maintain Active product status, ensuring long-term availability and continued manufacturing support. RC1206FR-073K57L includes moisture-resistant features. RMCF1206FT3K57 includes AEC-Q200 automotive qualification and Tape & Reel packaging, suitable for automated assembly processes.

Secondary Substitute (Automotive Applications):

RMCF1206FG3K57 (Stackpole Electronics Inc) is suitable for automotive applications requiring AEC-Q200 certification. This part is supplied in Cut Tape packaging, which may require manual handling or reel conversion for high-volume automated assembly.

Legacy Substitute (Restricted Use):

ERJ-8ENF3571V (Panasonic Electronic Components) carries "Not For New Designs" status. This part is electrically equivalent but should not be selected for new product development. Use only when existing inventory must be maintained or legacy system repairs are required.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF3571V replace RMC1/8K3571FTP in new designs?

A: No. ERJ-8ENF3571V is classified as "Not For New Designs." While electrically equivalent, Panasonic has discontinued this product line. New designs must use Active-status alternatives such as RC1206FR-073K57L or RMCF1206FT3K57.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape supplies individual pieces or short tape segments, typically requiring manual handling or reel conversion. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: RC1206FR-073K57L, RMCF1206FG3K57, and RMCF1206FT3K57 are confirmed RoHS3 compliant. RMC1/8K3571FTP and ERJ-8ENF3571V do not list RoHS status in provided specifications.

Q: Which substitute is recommended for automotive applications?

A: RMCF1206FT3K57 or RMCF1206FG3K57 (both Stackpole Electronics Inc) carry AEC-Q200 automotive qualification. RMCF1206FT3K57 is preferred due to Tape & Reel packaging and Active product status.

Q: Do physical dimension variations affect substitution?

A: All parts conform to 1206 (3216 Metric) package specification. Minor dimension variations (length 3.10mm vs. 3.20mm, height 0.65mm vs. 0.70mm) fall within package tolerance and do not prevent substitution. Verify PCB footprint design accommodates maximum stated dimensions.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. All listed parts carry MSL 1 rating, eliminating moisture-related handling constraints.
