Substitute Part Grouping Explanation

Substitute parts for the ERO-S2PHF3301 are qualified based on the following electrical and mechanical parameters:

• Resistance Value: 3.3 kOhms (exact match required)
• Tolerance: ±1% (precision specification maintained)
• Power Rating: 0.25W, 1/4W (functional equivalence)
• Composition: Metal Film (performance characteristics)
• Temperature Coefficient: ±50ppm/°C (stability requirement)
• Package Type: Axial (mechanical compatibility)
• Number of Terminations: 2 (circuit interface requirement)

The RNMF14FTC3K30 from Stackpole Electronics Inc meets all these criteria and qualifies as a direct substitute. Physical dimensions show minor variations within acceptable tolerances for through-hole mounting applications.

Parameter Comparison

Engineering Selection Recommendations

The RNMF14FTC3K30 is the qualified substitute for the obsolete ERO-S2PHF3301. Selection is based on:

• Electrical Equivalence: Identical resistance value, tolerance, power rating, temperature coefficient, and operating temperature range (with 5°C extended upper limit)
• Mechanical Compatibility: Axial package type with equivalent through-hole mounting interface
• Product Availability: Active product status with established supply chain
• Regulatory Compliance: ROHS3 compliant and REACH unaffected, meeting current environmental standards
• Composition Match: Metal film construction ensures equivalent performance characteristics in precision circuit applications

The substitute part includes flame retardant coating and safety features not specified in the original part, providing enhanced reliability without compromising functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC3K30 be used as a direct replacement for ERO-S2PHF3301?

A: Yes. Both parts share identical electrical specifications: 3.3 kOhms resistance, ±1% tolerance, 0.25W power rating, ±50ppm/°C temperature coefficient, and axial package configuration. The substitute operates across -55°C to 155°C, covering the original part's -55°C to 150°C range.

Q: Are there physical dimension differences between these parts?

A: Minor dimensional variations exist. The ERO-S2PHF3301 measures 0.067" diameter × 0.126" length (1.70mm × 3.20mm), while the RNMF14FTC3K30 measures 0.070" diameter × 0.130" length (1.78mm × 3.30mm). These differences are within acceptable tolerances for standard through-hole PCB mounting.

Q: What is the significance of the flame retardant coating on the substitute part?

A: The flame retardant coating on the RNMF14FTC3K30 is an additional safety feature that does not affect electrical performance or circuit compatibility. It provides enhanced protection in applications subject to thermal stress or safety certifications requiring flame retardancy.

Q: Does the substitute part meet current environmental regulations?

A: Yes. The RNMF14FTC3K30 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in most jurisdictions.

Q: Are there inventory or packaging differences?

A: The substitute part is supplied in Cut Tape (CT) packaging with significantly higher inventory availability (40,026 pcs vs. 997 pcs for the original part), ensuring reliable sourcing for production applications.
