Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERO-S2GHF1150 is determined by strict equivalence across the following parameters:

• Resistance value: 115 Ohms (exact match required)
• Tolerance: ±1% (electrical precision requirement)
• Power rating: 0.25W / 1/4W (thermal and current handling capacity)
• Composition: Metal Film (performance and stability characteristics)
• Temperature coefficient: ±50ppm/°C (frequency and temperature stability)
• Package type: Axial (mechanical and PCB compatibility)
• Number of terminations: 2 (circuit connectivity)

The CMF50115R00FHEB from Vishay Dale meets all these core substitution criteria and is classified as an active product, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CMF50115R00FHEB is the qualified substitute for the ERO-S2GHF1150 based on the following factors:

• All core electrical parameters match exactly: resistance, tolerance, power rating, composition, and temperature coefficient
• The operating temperature range of the substitute (-55°C ~ 175°C) exceeds the original specification (-55°C ~ 150°C), providing extended thermal capability
• The substitute is an active product with confirmed inventory availability, eliminating procurement risk associated with the obsolete original part
• ROHS3 compliance of the substitute aligns with modern regulatory requirements, whereas the original part is RoHS non-compliant
• Physical dimensions are within acceptable tolerance for axial through-hole PCB mounting, with minor variations in diameter (0.065" vs 0.067") and length (0.150" vs 0.126")
• Both components feature identical termination configuration (2-pin axial) and identical ECCN/HTSUS classifications

Frequently Asked Questions (FAQ)

Q: Can the CMF50115R00FHEB be used as a direct replacement for the ERO-S2GHF1150?

A: Yes. Both components share identical electrical specifications (115 Ohms ±1%, 0.25W, metal film, ±50ppm/°C). The substitute is mechanically compatible for axial through-hole mounting with negligible dimensional variation.

Q: What is the difference in operating temperature range?

A: The ERO-S2GHF1150 operates from -55°C to 150°C, while the CMF50115R00FHEB operates from -55°C to 175°C. The substitute provides a 25°C higher upper temperature limit, which is advantageous for thermal margin in circuit design.

Q: Are there physical size differences that affect PCB layout?

A: Minor dimensional differences exist. The substitute is 0.065" in diameter (vs 0.067") and 0.150" in length (vs 0.126"). These variations are within standard PCB hole tolerances for axial components and do not require layout modification.

Q: What is the RoHS compliance status of each part?

A: The ERO-S2GHF1150 is RoHS non-compliant. The CMF50115R00FHEB is ROHS3 compliant, meeting current environmental and regulatory standards for electronic components.

Q: Is the substitute part currently available?

A: Yes. The CMF50115R00FHEB is classified as an active product with 1941 pieces in stock, ensuring reliable procurement compared to the obsolete ERO-S2GHF1150.

Q: Do both parts have the same packaging format?

A: Both components use axial through-hole packaging with 2 terminations. The substitute is supplied in Cut Tape (CT) packaging format.
