RMC1/4-162JTE Equivalent & Substitute Parts

Part Overview

The RMC1/4-162JTE is a 1.6 kOhms ±5% 0.5W thick film chip resistor manufactured by Kamaya Inc. in the 1210 (3225 Metric) package format. This component is currently in Active product status and is supplied in Tape & Reel packaging with 685 pieces available in stock.

Substitute parts become necessary when the primary manufacturer experiences supply constraints, when design requirements mandate specific certifications such as automotive qualification, or when alternative sourcing improves cost efficiency while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/4-162JTE is determined by strict equivalence across the following parameters:

Mandatory Matching Parameters:

• Resistance value: 1.6 kOhms
• Tolerance: ±5%
• Power rating: 0.5W (1/2W)
• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: MSL 1 or better
• Number of terminations: 2

The ERJ-14YJ162U manufactured by Panasonic Electronic Components meets all mandatory electrical and mechanical parameters. This substitute maintains identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. The primary distinction is the inclusion of AEC-Q200 automotive qualification in the Panasonic component, which represents an additional certification rather than a deviation from base specifications.

Engineering Selection Recommendations

Primary Selection (RMC1/4-162JTE): The RMC1/4-162JTE is the specified component with Active product status. Selection of this part is appropriate for applications where Kamaya Inc. supply chain availability is confirmed and no additional automotive or compliance certifications are mandated.

Substitute Selection (ERJ-14YJ162U): The ERJ-14YJ162U is electrically and mechanically equivalent and carries AEC-Q200 automotive qualification. This substitute is suitable for applications requiring automotive-grade components or when Panasonic supply chain access is preferred. Note that this part carries "Not For New Designs" status, indicating that Panasonic recommends it for legacy or existing design support only. The dimensional variance (length 3.20mm vs. 3.10mm) is within standard PCB layout tolerances for 1210 package footprints.

Selection between these parts should be based on supply availability, design certification requirements, and existing qualification documentation rather than electrical performance, as both components are functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14YJ162U be used as a direct replacement for RMC1/4-162JTE in existing designs?

A: Yes. Both components share identical electrical specifications (1.6 kOhms ±5%, 0.5W, ±200ppm/°C, -55°C to 155°C) and are packaged in the 1210 (3225 Metric) format. The 0.10mm length difference (3.20mm vs. 3.10mm) falls within standard PCB design tolerances for this package class.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14YJ162U?

A: This designation indicates that Panasonic recommends the ERJ-14YJ162U for continuation of existing designs and legacy applications only. New designs should reference current Panasonic product lines. However, this status does not affect functional compatibility or performance in existing applications.

Q: Does the AEC-Q200 certification on the ERJ-14YJ162U add any performance advantage?

A: AEC-Q200 is an automotive qualification standard that certifies component reliability under automotive environmental and operational conditions. It does not alter the electrical or thermal performance of the resistor itself. Selection based on AEC-Q200 is driven by application requirements (automotive use) rather than performance enhancement.

Q: Are there dimensional concerns when substituting these parts on existing PCBs?

A: The length difference of 0.10mm (3.10mm to 3.20mm) is negligible for standard 1210 package footprints. Both components maintain identical height (0.70mm maximum) and width (2.50mm). No PCB layout modifications are required.

Q: What compliance certifications apply to both parts?

A: Both RMC1/4-162JTE and ERJ-14YJ162U are REACH Unaffected and carry ECCN EAR99 classification. The ERJ-14YJ162U additionally carries ROHS3 Compliant certification.
