Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Resistance value: 100 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial Through-Hole (exact match required)
• Compliance: ROHS3 Compliant (minimum requirement)

Two substitute parts meet these criteria with variations in packaging format and thermal performance:

RNF14BTE100K (Stackpole Electronics Inc): Identical electrical specifications to the main part with packaging format change from Tape & Reel (TR) to Cut Tape (CT). Temperature coefficient improves to ±25ppm/°C. Operating temperature range remains -55°C ~ 155°C.

CPF1100K00BHEE6 (Vishay Dale): Meets core electrical requirements with power rating upgrade to 1W, extended operating temperature range (-65°C ~ 230°C), and enhanced environmental features (flame proof, moisture resistant). Packaging format is Cut Tape (CT).

Parameter Comparison

Engineering Selection Recommendations

RNF14BTE100K is the direct functional equivalent with identical electrical performance. Selection is appropriate when Cut Tape (CT) packaging format is acceptable and improved temperature coefficient (±25ppm/°C) provides design margin benefit. Both parts maintain ROHS3 compliance and active production status.

CPF1100K00BHEE6 provides enhanced thermal capability with 1W power rating and extended operating temperature range (-65°C ~ 230°C). This part is suitable for applications requiring higher power dissipation margin or operation in extended temperature environments. The Vishay Dale CPF series maintains ROHS3 compliance and active production status. Physical dimensions differ slightly (0.090" Dia x 0.240" L versus 0.093" Dia x 0.250" L), requiring PCB layout verification.

All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0090.

Frequently Asked Questions (FAQ)

Q: Can RNF14BTE100K replace RNF14BTC100K in all applications?

A: Yes, from an electrical standpoint. Both parts have identical resistance (100 kOhms), tolerance (±0.1%), power rating (0.25W), composition (metal film), and operating temperature range (-55°C ~ 155°C). The primary difference is packaging format: RNF14BTC100K is supplied in Tape & Reel (TR) while RNF14BTE100K is Cut Tape (CT). RNF14BTE100K offers improved temperature coefficient (±25ppm/°C versus ±50ppm/°C). Verify packaging compatibility with assembly equipment and procurement processes.

Q: When should CPF1100K00BHEE6 be selected over the RNF14BTC100K?

A: CPF1100K00BHEE6 is selected when applications require higher power dissipation capability (1W versus 0.25W) or extended operating temperature range (-65°C ~ 230°C versus -55°C ~ 155°C). The Vishay Dale part also provides flame proof and moisture resistant features. Physical dimensions are slightly smaller. Verify PCB layout compatibility before substitution.

Q: Are all three parts suitable for high-reliability applications?

A: All three parts are ROHS3 compliant and maintain active production status. Selection depends on specific application requirements for power rating, temperature range, and environmental features. Consult design specifications and qualification requirements for your application.

Q: What is the impact of different packaging formats?

A: RNF14BTC100K (Tape & Reel) and RNF14BTE100K (Cut Tape) differ in supply format only. Tape & Reel is optimized for high-volume automated assembly, while Cut Tape is suitable for lower-volume or mixed-component applications. Electrical performance is identical. Verify compatibility with your assembly process and equipment.

Q: Can physical dimension differences affect PCB design?

A: CPF1100K00BHEE6 has slightly different dimensions (0.090" Dia x 0.240" L) compared to RNF14BTC100K (0.093" Dia x 0.250" L). For most through-hole applications, this difference is negligible. However, verify PCB layout, hole spacing, and component clearance requirements before substitution in space-constrained designs.
