Vishay Dale RN55C1001CRSL Equivalent & Substitute Parts Reference

Part Overview

The Vishay Dale RN55C1001CRSL is a 1 kOhms ±0.25%, 0.125W (1/8W) metal film axial resistor featuring flame retardant coating, military-grade reliability, moisture resistance, and safety features. It is part of the Military, MIL-R-10509/7, RN55 series, supplied in Tape & Reel (TR) packaging. This resistor is active and RoHS non-compliant. Finding and verifying substitute models is necessary in cases where specific tolerance, temperature coefficient, or packaging preferences are required, or when managing supply constraints or compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection for this resistor category is determined by explicit matching of these parameters: resistance value, power rating, tolerance, temperature coefficient, composition, features, size and dimension, package/case, operating temperature, series, number of terminations, and compliance status. All substitute parts listed here are from the same series, have identical resistance, power rating, physical dimensions, composition, features, and mechanical package. Variations are present in tolerance, temperature coefficient, packaging, and inventory status; all listed substitutes are RoHS non-compliant and share equivalent compliance attributes.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—RN55E1001BB14 and RN55E1001BRE6—are active, have identical electrical and mechanical parameters to the RN55C1001CRSL except for improved tolerance and temperature coefficient. All parts are RoHS non-compliant and REACH affected. Selection among these parts is determined by packaging preferences and compliance consistency.

Frequently Asked Questions (FAQ)

Q: Are RN55E1001BB14 and RN55E1001BRE6 direct substitutes for RN55C1001CRSL?
A: Yes. They match on resistance, power rating, composition, features, size, series, and other key electrical and mechanical parameters.

Q: What is the main difference between the original RN55C1001CRSL and its substitutes?
A: RN55E1001BB14 and RN55E1001BRE6 offer tighter tolerance (±0.1% vs. ±0.25%) and a lower temperature coefficient (±25ppm/°C vs. ±50ppm/°C). Packaging options differ (Bulk and Cut Tape vs. Tape & Reel).

Q: Are there considerations regarding RoHS and REACH?
A: All parts listed, including the main and substitute resistors, are RoHS non-compliant and REACH affected.

Q: Do these substitutes differ in physical size or termination?
A: No. All listed parts have an identical axial package, size, and number of terminations.

Q: Can differences in packaging impact compatibility?
A: Packaging affects only handling and assembly process preferences, not electrical or mechanical compatibility.
