Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSMF2JA27K0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 27 kOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package configuration: Axial
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• Physical dimensions: 0.177" Dia x 0.433" L (4.50mm x 11.00mm)
• Termination count: 2
• Compliance certifications: ROHS3, REACH Unaffected

The identified substitute differs only in packaging format (Cut Tape versus Tape & Box), maintaining full electrical and mechanical equivalence. Both parts are manufactured by Stackpole Electronics Inc within the RSMF series and carry Active product status.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF2JA27K0 and RSMF2JT27K0 are qualified for direct substitution in applications requiring 27 kOhms ±5% 2W axial metal oxide film resistors. Selection between these parts should be based on assembly process requirements and packaging logistics:

RSMF2JA27K0 (Tape & Box packaging) is suitable for applications where bulk storage and manual component handling are standard practice.

RSMF2JT27K0 (Cut Tape packaging) is suitable for automated pick-and-place assembly systems and applications requiring smaller packaging units.

Both parts maintain identical electrical performance, thermal characteristics, and regulatory compliance (ROHS3, REACH Unaffected). No performance degradation or functional limitation occurs when substituting between these part numbers within the same application circuit.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT27K0 be used as a direct replacement for RSMF2JA27K0?

A: Yes. Both parts are electrically and mechanically equivalent. The only difference is packaging format (Cut Tape versus Tape & Box). No circuit modifications or performance adjustments are required.

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

A: Tape & Box (TB) packaging provides components on continuous tape with a protective box for storage. Cut Tape (CT) packaging provides components on cut tape segments. Both formats contain identical components; the difference is in delivery and handling format.

Q: Are both parts ROHS3 compliant?

A: Yes. Both RSMF2JA27K0 and RSMF2JT27K0 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can these resistors be used in high-temperature applications?

A: Yes. Both parts operate across the temperature range -55°C to 235°C with a temperature coefficient of ±200ppm/°C, making them suitable for high-temperature industrial and automotive applications.

Q: Are there any circuit design considerations when selecting between these substitute parts?

A: No. Both parts have identical electrical specifications, power ratings, tolerance, and thermal characteristics. Selection is based solely on packaging and procurement requirements.
