Substitute Part Grouping Explanation

Substitution of the RN55E2001DRSL is permissible with parts meeting the following criteria:

• Identical resistance value: 2 kOhms
• Equal or tighter tolerance specification (±0.5% or better)
• Equal or greater power rating: 0.125W minimum
• Identical composition: Metal Film
• Identical package: Axial configuration
• Identical or compatible temperature coefficient: ±25ppm/°C
• Operating temperature range encompassing or exceeding -65°C to 175°C
• Same military series designation: RN55, MIL-R-10509/7 compliance

The RN55E2001BB14 qualifies as a direct substitute based on these parameters, with the distinction of offering improved tolerance specification (±0.1% versus ±0.5%).

Parameter Comparison

Engineering Selection Recommendations

Both the RN55E2001DRSL and RN55E2001BB14 are active products from Vishay Dale within the military-grade RN55 series. The RN55E2001BB14 provides superior tolerance performance at ±0.1% compared to the ±0.5% specification of the main part, while maintaining identical electrical and thermal characteristics. Selection between these parts should be based on packaging requirements: the main part is supplied in Tape & Reel format suitable for automated assembly, while the substitute is supplied in Bulk packaging. Both parts carry identical compliance status regarding RoHS non-compliance and REACH affectation. Component selection should align with procurement specifications, assembly methodology, and tolerance requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can RN55E2001BB14 be used as a direct replacement for RN55E2001DRSL?

A: Yes. Both parts share identical resistance, power rating, package configuration, temperature range, and military series designation. The substitute offers tighter tolerance (±0.1% versus ±0.5%), making it functionally compatible and electrically superior for applications requiring precision resistance values.

Q: What is the primary difference between these two parts?

A: The main differences are tolerance specification and packaging format. RN55E2001DRSL specifies ±0.5% tolerance in Tape & Reel packaging, while RN55E2001BB14 specifies ±0.1% tolerance in Bulk packaging.

Q: Are there packaging compatibility considerations?

A: Yes. The main part (RN55E2001DRSL) is supplied in Tape & Reel format for automated pick-and-place assembly. The substitute (RN55E2001BB14) is supplied in Bulk format, requiring manual handling or alternative assembly processes. Verify that your assembly methodology accommodates the packaging format of the selected part.

Q: Do both parts meet military specifications?

A: Yes. Both parts are manufactured to MIL-R-10509/7 specifications and are designated as military-grade components within the RN55 series. Both maintain identical operating temperature range (-65°C to 175°C) and feature flame retardant coating with moisture resistance.

Q: What compliance certifications apply to these parts?

A: Both parts are RoHS non-compliant and REACH Affected. Both carry ECCN classification EAR99 and HTSUS code 8533.21.0090. Verify compliance requirements for your specific application and regulatory jurisdiction.
