Substitute Part Grouping Explanation

Substitution for the RN55C2002BBSL is determined by the following critical parameters that must remain constant across all equivalent parts:

• Resistance value: 20 kOhms
• Tolerance: ±0.1%
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Package: Axial
• Operating temperature range: -65°C to 175°C
• Series compliance: Military, MIL-R-10509/7, RN55

The substitute parts are grouped into two categories:

Upgrade Parts (RN55E2002BB14, RN55E2002BRE6): These parts maintain all critical electrical parameters while offering improved temperature coefficient performance (±25ppm/°C versus ±50ppm/°C). The primary distinction between these upgrade options is packaging format: RN55E2002BB14 is supplied in Bulk packaging, while RN55E2002BRE6 is supplied in Cut Tape (CT) packaging.

Parametric Equivalent (RN55C2002BB14): This part matches the main part specification identically, including the ±50ppm/°C temperature coefficient, with the only distinction being packaging format (Bulk).

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain Active product status and are manufactured by Vishay Dale within the Military MIL-R-10509/7 RN55 series. Selection between these parts should be based on the following criteria:

RN55C2002BBSL (Original): Select when the original specification with ±50ppm/°C temperature coefficient is required and Bulk packaging is acceptable. Current inventory of 1017 pieces supports immediate availability.

RN55E2002BB14 (Upgrade - Bulk): Select when improved temperature stability (±25ppm/°C) is beneficial and Bulk packaging is required. This upgrade option provides tighter temperature coefficient performance while maintaining identical mechanical and electrical characteristics. Inventory of 1118 pieces ensures availability.

RN55E2002BRE6 (Upgrade - Cut Tape): Select when improved temperature stability (±25ppm/°C) is required and Cut Tape packaging format is preferred for automated assembly processes. This option offers the highest inventory level at 3902 pieces, supporting high-volume production requirements.

RN55C2002BB14 (Parametric Equivalent): Select when exact specification matching to the original part is required, including ±50ppm/°C temperature coefficient, with Bulk packaging. Inventory of 1849 pieces provides adequate supply.

All parts comply with RoHS non-compliant status, REACH Affected designation, ECCN EAR99, and HTSUS 8533.21.0090 classification consistent with the original specification.

Frequently Asked Questions (FAQ)

Q: Can RN55E2002BB14 and RN55E2002BRE6 be used interchangeably with RN55C2002BBSL?

A: Yes, both upgrade parts are electrically and mechanically compatible. The primary differences are improved temperature coefficient (±25ppm/°C versus ±50ppm/°C) and packaging format. RN55E2002BB14 uses Bulk packaging identical to the original, while RN55E2002BRE6 uses Cut Tape packaging. Selection depends on assembly process requirements and temperature stability needs.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging supplies components loose in a container, suitable for manual assembly or small-batch operations. Cut Tape packaging supplies components on continuous tape, optimized for automated pick-and-place assembly equipment. Both formats contain identical components; packaging selection depends on manufacturing process requirements.

Q: Is RN55C2002BB14 a direct replacement for RN55C2002BBSL?

A: Yes, RN55C2002BB14 is a parametric equivalent with identical electrical specifications including ±50ppm/°C temperature coefficient. The only distinction is packaging format (Bulk). This part maintains complete compatibility with the original specification.

Q: Which substitute part offers the best temperature stability?

A: Both RN55E2002BB14 and RN55E2002BRE6 offer improved temperature coefficient performance at ±25ppm/°C compared to the original ±50ppm/°C specification. Selection between these two upgrade options depends solely on packaging format preference: Bulk or Cut Tape.

Q: Are all substitute parts compliant with the same military specifications?

A: Yes, all four parts are manufactured within the Military MIL-R-10509/7 RN55 series and maintain identical compliance designations including RoHS non-compliant status, REACH Affected, ECCN EAR99, and HTSUS 8533.21.0090 classification.
