Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Resistance value: 2.7 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 3W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.217" Dia x 0.591" L (exact match required)
• Regulatory compliance: ROHS3 Compliant (minimum requirement)

The RSMF3JT2K70 qualifies as a direct substitute based on identical electrical specifications and physical form factor. Differences exist in packaging format (Cut Tape vs. Tape & Box), temperature coefficient, and maximum operating temperature, which do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both RSPF3JA2K70 and RSMF3JT2K70 are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Packaging requirements: RSPF3JA2K70 is supplied in Tape & Box format; RSMF3JT2K70 is supplied in Cut Tape format
• Temperature performance: RSMF3JT2K70 supports extended operation to 235°C versus 155°C for RSPF3JA2K70
• Temperature coefficient stability: RSMF3JT2K70 offers symmetrical ±200ppm/°C versus asymmetrical -200/+350ppm/°C for RSPF3JA2K70

Both parts meet identical electrical and mechanical specifications for standard circuit applications within the -55°C to 155°C range.

Frequently Asked Questions (FAQ)

Q: Can RSMF3JT2K70 be used as a direct replacement for RSPF3JA2K70?

A: Yes. Both parts have identical resistance, tolerance, power rating, composition, and physical dimensions. The primary difference is packaging format and extended temperature capability of the RSMF3JT2K70.

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

A: Tape & Box (TB) packaging includes a protective box for storage and handling. Cut Tape (CT) packaging provides individual component lengths cut from continuous tape. Both formats contain the same component; selection depends on assembly process requirements and inventory management practices.

Q: Does the higher maximum operating temperature of RSMF3JT2K70 affect circuit performance?

A: The extended temperature range of RSMF3JT2K70 (-55°C to 235°C) does not affect performance in applications operating within the -55°C to 155°C range. The difference in temperature coefficient (±200ppm/°C vs. -200/+350ppm/°C) may be relevant only in precision applications requiring tight resistance stability across temperature extremes.

Q: Are both parts RoHS compliant?

A: Yes. Both RSPF3JA2K70 and RSMF3JT2K70 are ROHS3 compliant and REACH unaffected.

Q: What inventory levels are available?

A: RSPF3JA2K70 has 680 units in stock. RSMF3JT2K70 has 1900 units in stock.
