Key Parameters

Substitute Part Grouping Explanation

Substitution of the RSMF2GT22R0 is permissible when the replacement part maintains the following critical parameters:

• Resistance value: 22 Ohms
• Tolerance: ±2%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package configuration: Axial with 2 terminations
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• RoHS3 compliance status

The RSF2GT22R0 qualifies as a direct substitute based on these electrical and mechanical specifications. Physical dimensions may vary within acceptable assembly tolerances for through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RSMF2GT22R0 and RSF2GT22R0 are active production parts from Stackpole Electronics Inc with identical electrical specifications and regulatory compliance. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Physical dimension compatibility with PCB layout constraints (RSMF2GT22R0: 4.50mm diameter × 11.00mm length; RSF2GT22R0: 5.50mm diameter × 15.00mm length)
• Packaging format requirements (both available in Tape & Reel)
• Supply chain logistics and cost considerations

Both parts satisfy ROHS3 compliance, REACH unaffected status, and EAR99 export classification requirements.

Frequently Asked Questions (FAQ)

Q: Can RSF2GT22R0 be used as a direct replacement for RSMF2GT22R0?

A: Yes. Both parts share identical electrical specifications (22 Ohms ±2%, 2W, metal oxide film composition, ±200ppm/°C temperature coefficient, -55°C to 235°C operating range). Physical dimensions differ; verify PCB layout clearances before substitution.

Q: What is the difference between RSMF and RSF series designations?

A: The series designation reflects internal Stackpole product line categorization. The RSMF series features flame proof construction, while the RSF series features flame retardant coating. Both provide equivalent electrical performance and safety certification for the specified parameters.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 classification. Regulatory requirements are satisfied by either part.

Q: What should be considered when substituting based on physical dimensions?

A: The RSF2GT22R0 is larger (5.50mm diameter × 15.00mm length) compared to the RSMF2GT22R0 (4.50mm diameter × 11.00mm length). Verify that PCB footprint spacing, component density, and thermal management requirements accommodate the larger package before implementation.

Q: Are both parts available in the same packaging format?

A: Yes. Both RSMF2GT22R0 and RSF2GT22R0 are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
