Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSPF1JA100R is determined by the following critical parameters:

• Resistance value: 100 Ohms
• Tolerance: ±5%
• Power rating: 1W
• Composition: Metal Oxide Film
• Package configuration: Axial through hole
• Compliance: ROHS3 Compliant

The RSMF1JT100R qualifies as a substitute based on matching all critical electrical parameters and package type. Both parts share identical resistance, tolerance, power rating, and composition. Differences in packaging format (Tape & Box versus Cut Tape), physical dimensions, temperature coefficient range, and maximum operating temperature do not prevent functional substitution in applications where the RSPF1JA100R is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the RSPF1JA100R and RSMF1JT100R are Active status products manufactured by Stackpole Electronics Inc and maintain ROHS3 compliance. Selection between these parts should be based on:

Packaging requirements: The RSPF1JA100R is supplied in Tape & Box format, while the RSMF1JT100R is supplied in Cut Tape format. Choose based on assembly process and inventory management needs.

Temperature environment: The RSMF1JT100R supports operation to 200°C maximum, compared to 155°C for the RSPF1JA100R. For applications requiring extended high-temperature performance, the RSMF1JT100R provides additional thermal margin.

Physical space constraints: The RSMF1JT100R has a slightly larger diameter (0.126" versus 0.118"). Verify PCB layout compatibility before substitution in space-constrained designs.

Both parts satisfy identical electrical specifications and regulatory requirements for standard 100 Ohm 1W resistor applications.

Frequently Asked Questions (FAQ)

Can RSMF1JT100R replace RSPF1JA100R in my circuit?

Yes. Both parts share identical electrical specifications: 100 Ohms resistance, ±5% tolerance, and 1W power rating. The metal oxide film composition and axial package configuration are identical. Verify physical dimensions fit your PCB layout, as the RSMF1JT100R has a slightly larger diameter.

What is the difference between Tape & Box and Cut Tape packaging?

Tape & Box packaging (RSPF1JA100R) includes a full reel with protective box, suitable for manual assembly or smaller production runs. Cut Tape packaging (RSMF1JT100R) provides individual components on tape segments, optimized for automated pick-and-place assembly systems.

Are both parts RoHS compliant?

Yes. Both RSPF1JA100R and RSMF1JT100R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Which part should I use for high-temperature applications?

The RSMF1JT100R supports continuous operation to 200°C, compared to 155°C for the RSPF1JA100R. For applications approaching or exceeding 155°C, the RSMF1JT100R provides additional thermal headroom.

Do the physical dimension differences affect PCB design?

The RSMF1JT100R diameter is 0.008" (0.20mm) larger than the RSPF1JA100R. Both maintain the same 0.354" length. Verify hole spacing and component clearances on your PCB before substitution.
