Key Parameters

Substitute Part Grouping Explanation

The RSMF2JT22R0 qualifies as a substitute for the RSPF2JT22R0 based on the following criteria:

Matching Parameters:

• Resistance value: 22 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package: Axial
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• REACH status: REACH Unaffected

Allowable Variations:

• Operating temperature range: RSMF2JT22R0 extends to 235°C (versus 155°C for RSPF2JT22R0), providing enhanced thermal capability
• Temperature coefficient: RSMF2JT22R0 is ±200ppm/°C (versus -200/+350ppm/°C for RSPF2JT22R0), offering improved stability
• Physical dimensions: Minor diameter increase (4.50mm versus 4.00mm) with identical length (11.00mm)
• Features: RSMF2JT22R0 omits moisture resistance designation but retains flame-proof construction

Parameter Comparison

Engineering Selection Recommendations

Both RSPF2JT22R0 and RSMF2JT22R0 are active production parts from Stackpole Electronics Inc with full ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific thermal and stability requirements:

The RSPF2JT22R0 is suitable for applications operating within -55°C to 155°C with moisture-resistant requirements. The RSMF2JT22R0 provides superior performance in high-temperature environments up to 235°C and offers tighter temperature coefficient control at ±200ppm/°C. Both parts maintain identical electrical specifications (22 Ohms ±5%, 2W) and axial package compatibility. The minor diameter increase in the RSMF2JT22R0 (4.50mm versus 4.00mm) must be verified for PCB layout clearance in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT22R0 directly replace RSPF2JT22R0 in all applications?

A: Direct replacement is possible when the application does not require moisture resistance and can accommodate the slightly larger diameter (4.50mm versus 4.00mm). Both parts share identical resistance, tolerance, power rating, and axial package configuration. PCB layout verification is necessary to confirm clearance for the increased diameter.

Q: What is the significance of the temperature coefficient difference?

A: The RSPF2JT22R0 has a temperature coefficient of -200/+350ppm/°C, while the RSMF2JT22R0 is ±200ppm/°C. The RSMF2JT22R0 provides more symmetrical and predictable resistance variation across temperature extremes, beneficial for precision circuits. The RSPF2JT22R0 is acceptable for applications with less stringent stability requirements.

Q: Why does the RSMF2JT22R0 have a higher maximum operating temperature?

A: The RSMF2JT22R0 is rated to 235°C versus 155°C for the RSPF2JT22R0. This extended thermal capability is inherent to the RSMF series design and does not affect substitution eligibility for applications operating within the lower temperature range.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both RSPF2JT22R0 and RSMF2JT22R0 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What packaging format is used for both parts?

A: Both parts are supplied in Tape & Reel (TR) packaging, standard for automated assembly processes. This packaging format is identical between the two parts.
