Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSMF2JB12K0 is determined by the following critical parameters:

• Resistance value: 12 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package type: Axial (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C to 235°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The RSF2JT12K0 meets all substitution criteria. Both parts share identical electrical specifications and environmental ratings. The primary difference is packaging format (Bulk versus Cut Tape) and physical dimensions, which do not affect electrical performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RSF2JT12K0 is a direct electrical equivalent to the RSMF2JB12K0. Both parts are manufactured by Stackpole Electronics Inc, maintain identical electrical specifications, and carry equivalent regulatory compliance certifications (ROHS3 Compliant, REACH Unaffected, EAR99 classification).

Selection between these parts should be based on:

• Packaging requirements: RSMF2JB12K0 is supplied in Bulk format; RSF2JT12K0 is supplied in Cut Tape (CT) format
• Physical space constraints: RSF2JT12K0 has larger physical dimensions (5.50mm diameter, 15.00mm length) compared to RSMF2JB12K0 (4.50mm diameter, 11.00mm length)
• Inventory availability: RSF2JT12K0 has higher stock availability (2420 units) versus RSMF2JB12K0 (656 units)

Both parts are active products with no product status concerns.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT12K0 be used as a direct replacement for RSMF2JB12K0 in circuit applications?

A: Yes. Both parts have identical electrical specifications: 12 kOhms resistance, ±5% tolerance, 2W power rating, ±200ppm/°C temperature coefficient, and -55°C to 235°C operating range. Electrical performance is equivalent.

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

A: Bulk packaging supplies loose components, while Cut Tape (CT) packaging provides components on adhesive tape in carrier strips. This affects handling, automated assembly compatibility, and storage requirements, but does not impact electrical characteristics.

Q: Are the physical dimension differences significant?

A: Physical dimensions differ between the two parts. RSF2JT12K0 is larger (5.50mm diameter, 15.00mm length) than RSMF2JB12K0 (4.50mm diameter, 11.00mm length). Verify available board space before substitution in space-constrained applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both RSMF2JB12K0 and RSF2JT12K0 are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes.

Q: Which part should be selected for new designs?

A: Selection depends on packaging preference and inventory requirements. Both parts are active products with equivalent electrical performance and regulatory compliance.
