Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55C3242CBSL is determined by the following critical parameters:

Resistance value must remain 32.4 kOhms. Power rating must be equal to or greater than 0.125W. Package configuration must be Axial to ensure mechanical compatibility with existing PCB layouts. Temperature coefficient and operating temperature range must support the intended application environment. Composition must be metal film to maintain electrical stability and reliability characteristics. Military series designation and compliance with MIL-R-10509/7 specification must be maintained.

The RN55C3242BB14 qualifies as a direct substitute based on these criteria. Both parts share identical resistance value, power rating, package type, temperature coefficient, operating temperature range, composition, and military series designation. The primary distinction is tolerance specification: RN55C3242BB14 provides ±0.1% tolerance compared to ±0.25% tolerance of the main part, representing an upgrade in precision capability.

Parameter Comparison

Engineering Selection Recommendations

Both RN55C3242CBSL and RN55C3242BB14 maintain Active product status with current manufacturer support and inventory availability. Selection between these parts depends on circuit tolerance requirements. The RN55C3242CBSL with ±0.25% tolerance is suitable for applications where standard precision meets design specifications. The RN55C3242BB14 with ±0.1% tolerance provides enhanced precision for circuits requiring tighter component value control.

Both parts comply with identical military specifications, environmental ratings, and regulatory requirements including REACH Affected status and RoHS non-compliant classification. Mechanical compatibility is assured through identical axial package dimensions and termination configuration. Thermal performance characteristics remain equivalent across both options.

Frequently Asked Questions (FAQ)

Q: Can RN55C3242BB14 be used as a direct replacement for RN55C3242CBSL?

A: Yes. Both parts share identical resistance value (32.4 kOhms), power rating (0.125W), package configuration (Axial), temperature coefficient (±50ppm/°C), operating temperature range (-65°C to 175°C), and physical dimensions (0.090" Dia x 0.240" L). The RN55C3242BB14 provides improved tolerance specification (±0.1% versus ±0.25%), making it suitable for applications requiring higher precision.

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

A: The tolerance specification differs. RN55C3242CBSL specifies ±0.25% tolerance, while RN55C3242BB14 specifies ±0.1% tolerance. All other electrical and mechanical parameters remain identical.

Q: Are there any package or footprint compatibility concerns?

A: No. Both parts use identical axial package configuration with matching physical dimensions (0.090" Dia x 0.240" L / 2.29mm x 6.10mm). PCB layout and mounting requirements are identical.

Q: Do both parts meet the same military specifications?

A: Yes. Both parts comply with MIL-R-10509/7 specification and are designated as Military series components. Environmental features including flame retardant coating, moisture resistance, and safety rating are identical.

Q: What are the regulatory compliance differences?

A: Both parts share identical regulatory status: RoHS non-compliant and REACH Affected. No compliance advantages exist between the two options.
