RNF14BTC31K2 Equivalent & Substitute Parts

Part Overview

The RNF14BTC31K2 is a 31.2 kOhms ±0.1% metal film through-hole resistor rated at 0.25W (1/4W) in axial package configuration. Manufactured by Stackpole Electronics Inc under the RNF series, this component features flame retardant coating and safety construction suitable for precision applications requiring tight tolerance specifications. The part maintains Active product status with ROHS3 compliance and is currently in stock inventory of 985 pieces.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same resistance value, tolerance class, power rating, and package type while accommodating variations in secondary parameters such as temperature coefficient and packaging format.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNF14BTC31K2 is determined by strict equivalence across the following critical parameters:

• Resistance value: 31.2 kOhms (exact match required)
• Tolerance class: ±0.1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Regulatory compliance: ROHS3 Compliant (exact match required)

Secondary parameters including temperature coefficient and packaging format (Tape & Reel versus Tape & Box) do not disqualify substitution when primary electrical and mechanical specifications remain identical. The RNF14BAE31K2 qualifies as a direct substitute based on full alignment with all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both RNF14BTC31K2 and RNF14BAE31K2 maintain Active product status from Stackpole Electronics Inc and satisfy ROHS3 compliance requirements. The RNF14BAE31K2 offers improved temperature coefficient performance at ±25ppm/°C compared to ±50ppm/°C for the RNF14BTC31K2, representing enhanced stability across the full operating temperature range of -55°C to 155°C. Both components are manufactured to identical electrical specifications with 31.2 kOhms resistance and ±0.1% tolerance. Selection between these parts should be based on packaging requirements: Tape & Reel format for the RNF14BTC31K2 or Tape & Box format for the RNF14BAE31K2.

Frequently Asked Questions (FAQ)

Q: Can RNF14BAE31K2 be used as a direct replacement for RNF14BTC31K2?

A: Yes. Both parts share identical resistance (31.2 kOhms), tolerance (±0.1%), power rating (0.25W), composition (metal film), package type (axial), operating temperature range (-55°C to 155°C), and regulatory compliance (ROHS3). The primary difference is packaging format and temperature coefficient.

Q: What is the difference in temperature coefficient between these parts?

A: The RNF14BTC31K2 has a temperature coefficient of ±50ppm/°C, while the RNF14BAE31K2 has ±25ppm/°C. The RNF14BAE31K2 provides superior temperature stability, resulting in lower resistance drift across temperature variations.
