ERJ-S14F7870U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F7870U is a 787 Ohm ±1% thick film chip resistor manufactured by Panasonic Electronic Components in the 1210 (3225 Metric) package format. Rated for 0.5W power dissipation with automotive AEC-Q200 qualification and anti-sulfur coating, this component is designed for automotive and industrial applications requiring high reliability in harsh environments. The part is currently in active production status with 936 units in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits equivalent alternatives from qualified manufacturers. All substitute candidates maintain identical electrical specifications and package dimensions while meeting the same automotive and environmental compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F7870U is determined by strict equivalence across the following parameters:

• Resistance value: 787 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W minimum
• Package format: 1210 (3225 Metric) with identical footprint dimensions
• Composition: Thick film construction
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• Automotive qualification: AEC-Q200 certification mandatory
• Environmental compliance: ROHS3 and REACH requirements

All identified substitute parts meet these criteria without exception. Substitution does not require design modification, PCB layout changes, or requalification of thermal performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

For new designs and active production programs, CRCW1210787RFKEA (Vishay Dale) and RMCF1210FT787R (Stackpole Electronics Inc) are the preferred substitutes. Both parts carry Active product status with full AEC-Q200 automotive qualification and ROHS3 compliance. These alternatives provide equivalent electrical performance and identical footprint compatibility.

ERJ-14NF7870U (Panasonic) is functionally equivalent but carries Not For New Designs status, making it suitable only for legacy system maintenance or existing production continuity where design changes are not permitted.

All substitute parts maintain identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. Selection between active alternatives may be based on supplier availability, lead time, or established procurement relationships without compromising circuit performance or reliability.

Frequently Asked Questions (FAQ)

Q: Can ERJ-S14F7870U be directly replaced with CRCW1210787RFKEA on existing PCBs?

A: Yes. Both parts share identical 1210 (3225 Metric) package dimensions, footprint, and termination configuration. No PCB layout modification is required.

Q: What is the significance of the "Not For New Designs" status on ERJ-14NF7870U?

A: This designation indicates the part is in mature production phase with no planned enhancements or long-term availability guarantees. It remains functionally equivalent and suitable for replacement in existing applications but should not be selected for new product development.

Q: Are all substitute parts automotive-qualified?

A: Yes. All listed substitutes carry AEC-Q200 certification, meeting automotive reliability and environmental stress testing requirements identical to the primary part.

Q: Does the height difference between CRCW1210787RFKEA (0.024" max) and other substitutes (0.028" max) affect compatibility?

A: No. The height variation remains within standard 1210 package specifications and does not impact PCB assembly, clearance, or thermal performance in standard applications.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed alternatives meet ROHS3 compliance requirements with MSL 1 (Unlimited) moisture sensitivity rating, matching the primary part's environmental certifications.
