RC5025F1623CS Equivalent & Substitute Parts

Part Overview

The RC5025F1623CS is a 162 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) surface mount package. This component is classified as Active product status and is currently in stock with 879 pieces available.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit alternative manufacturers meeting equivalent electrical and mechanical specifications. The ERJ-12SF1623U from Panasonic Electronic Components serves as a qualified substitute, though it carries a Not For New Designs status and features enhanced automotive-grade specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F1623CS is determined by strict alignment with the following parameters:

Mandatory Match Criteria:

• Resistance value: 162 kOhms (exact)
• Package type: 2010 (5025 Metric) (exact)
• Composition: Thick Film (exact)
• Tolerance: ±1% or better
• RoHS compliance: ROHS3 Compliant (exact)

Allowable Variance Criteria:

• Power rating: Must equal or exceed 0.667W
• Temperature coefficient: Must equal or be better than ±100ppm/°C
• Operating temperature range: Must encompass -55°C ~ 155°C
• Moisture sensitivity: Must equal or be better than MSL 1

The ERJ-12SF1623U from Panasonic meets all mandatory criteria and exceeds the power rating specification at 0.75W (3/4W), making it a valid electrical and mechanical substitute. Both components share identical resistance, tolerance, package dimensions, and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

RC5025F1623CS (Samsung Electro-Mechanics): Select this component for new designs and applications requiring active product status with unrestricted design lifecycle. The part is currently in production with established supply availability (879 pieces in stock). ROHS3 compliance and MSL 1 rating support deployment in moisture-sensitive environments without additional protective measures.

ERJ-12SF1623U (Panasonic Electronic Components): This substitute is suitable for replacement applications, legacy system maintenance, or situations where supply of the primary component is constrained. The part carries Not For New Designs status, indicating Panasonic has discontinued active promotion for new applications. However, the component meets all electrical and mechanical substitution criteria. The automotive-grade AEC-Q200 qualification provides enhanced reliability assurance for demanding environments. Higher inventory availability (3250 pieces) may support expedited procurement requirements. The 0.04mm increase in seated height (0.028" versus 0.026") remains within standard PCB assembly tolerances and does not affect electrical performance.

Both components are ROHS3 compliant, REACH unaffected, and classified under identical HTSUS and ECCN codes, supporting equivalent regulatory and trade compliance.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF1623U replace RC5025F1623CS in existing designs?

A: Yes. Both components share identical resistance (162 kOhms), tolerance (±1%), package type (2010/5025 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The substitute's higher power rating (0.75W versus 0.667W) and minimal height variance (0.028" versus 0.026") do not create compatibility issues. PCB layout and footprint remain unchanged.

Q: What is the significance of the "Not For New Designs" status on the ERJ-12SF1623U?

A: This designation indicates Panasonic has transitioned the ERJ-12SF1623U away from active promotion for new product development. The component remains available and functional for replacement, repair, and legacy system applications. New designs should prioritize the RC5025F1623CS or evaluate alternative active-status components from Panasonic's current product line.

Q: Are there differences in thermal performance between these two resistors?

A: No. Both components specify identical temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C). The ERJ-12SF1623U's higher power rating (0.75W) provides additional thermal margin but does not alter the temperature stability characteristics of the 162 kOhms resistance value.

Q: Does the height difference affect PCB assembly?

A: The 0.002" (0.04mm) height difference between seated maximums (0.026" for RC5025F1623CS versus 0.028" for ERJ-12SF1623U) falls within standard surface mount assembly tolerances and does not require PCB redesign or reflow profile adjustment.

Q: Are both components suitable for moisture-sensitive applications?

A: Yes. Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling and storage practices apply without requirement for dry-pack or desiccant protection.

Q: What is the packaging difference between these parts?

A: The RC5025F1623CS is supplied in standard packaging (not specified in detail). The ERJ-12SF1623U is supplied in Tape & Reel (TR) format, which is standard for high-volume automated assembly. This packaging difference does not affect component performance or electrical characteristics.
