Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55C1001BBSL is determined by the following critical parameters:

• Electrical Parameters: Resistance value (1 kOhms), tolerance (±0.1%), and power rating (0.125W) must remain identical
• Physical Parameters: Package type (Axial), dimensions (0.090" Dia x 0.240" L), and termination count (2) must match
• Material & Construction: Metal film composition with flame retardant coating and moisture resistance required
• Environmental Compliance: Operating temperature range (-65°C to 175°C) and military series designation (MIL-R-10509/7, RN55) must be maintained
• Packaging Format: Bulk or Cut Tape (CT) packaging options are interchangeable for component-level substitution

The substitute parts listed below meet all these criteria while offering variations in temperature coefficient performance and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and are manufactured by Vishay Dale within the military-grade RN55 series. Selection between these parts should be based on the following criteria:

RN55C1001BB14 (Parametric Equivalent): Identical electrical and thermal characteristics to the main part. Suitable for direct replacement in applications where temperature coefficient stability of ±50ppm/°C is acceptable. Bulk packaging format applies.

RN55E1001BB14 (Upgrade): Offers improved temperature coefficient performance at ±25ppm/°C, providing enhanced stability across the full operating temperature range. Maintains bulk packaging. Recommended for applications requiring tighter temperature-dependent tolerance control.

RN55E1001BRE6 (Upgrade): Functionally equivalent to RN55E1001BB14 with superior temperature coefficient (±25ppm/°C) but supplied in Cut Tape (CT) packaging format. Select this variant when automated assembly processes or tape-and-reel handling is required.

All parts comply with MIL-R-10509/7 military specifications, feature flame retardant coating, moisture resistance, and safety-rated construction. RoHS non-compliance status is consistent across all variants.

Frequently Asked Questions (FAQ)

Q: Can RN55E1001BB14 or RN55E1001BRE6 be used as direct replacements for RN55C1001BBSL?

A: Yes. Both upgrade parts maintain identical resistance (1 kOhms), tolerance (±0.1%), power rating (0.125W), package type (Axial), and operating temperature range (-65°C to 175°C). The primary difference is improved temperature coefficient performance (±25ppm/°C versus ±50ppm/°C), which enhances stability but does not prevent interchangeability.

Q: What is the difference between RN55C1001BB14 and RN55E1001BB14?

A: Both parts are electrically and mechanically identical except for temperature coefficient. RN55C1001BB14 has ±50ppm/°C while RN55E1001BB14 has ±25ppm/°C. The improved temperature coefficient in RN55E1001BB14 provides better resistance stability across temperature variations.

Q: Does packaging format (Bulk versus Cut Tape) affect electrical performance?

A: No. Packaging format does not affect electrical or mechanical performance. RN55E1001BRE6 in Cut Tape (CT) format is electrically identical to RN55E1001BB14 in Bulk format. Selection should be based on assembly process requirements and handling preferences.

Q: Are all substitute parts compliant with MIL-R-10509/7?

A: Yes. All listed parts are designated as military-grade components within the RN55 series and comply with MIL-R-10509/7 specifications. All feature flame retardant coating, moisture resistance, and safety-rated construction.

Q: What inventory availability should be considered?

A: Current inventory levels are: RN55C1001BBSL (1088 pcs), RN55C1001BB14 (2216 pcs), RN55E1001BB14 (1881 pcs), and RN55E1001BRE6 (1091 pcs). Availability may influence selection when immediate procurement is required.
