Substitute Part Grouping Explanation

Substitution eligibility for the RSMF2JB82R0 is determined by strict electrical and mechanical parameter matching:

Electrical Equivalence Criteria:

• Resistance value: 82 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 235°C (exact match required)

Mechanical Compatibility Criteria:

• Package type: Axial (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Criteria:

• RoHS Status: ROHS3 Compliant (exact match required)
• REACH Status: REACH Unaffected (exact match required)

Identified substitutes meet all electrical and compliance requirements. Packaging format variations (Bulk, Cut Tape, Tape & Reel) and physical dimension differences are secondary considerations that do not affect electrical performance or core mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RSMF2JB82R0, RSMF2JT82R0, and RSF2JT82R0—are electrically equivalent and meet identical compliance requirements. Selection between these parts should be based on:

Packaging and Supply Chain Requirements:

• RSMF2JB82R0 (Bulk packaging) is suitable for applications where components are hand-selected or used in low-volume assembly processes.
• RSMF2JT82R0 (Cut Tape packaging) accommodates semi-automated assembly equipment and moderate production volumes.
• RSF2JT82R0 (Tape & Reel packaging) is optimized for high-volume automated assembly operations.

Inventory and Availability: All parts maintain active production status with ROHS3 compliance and REACH unaffected certification, ensuring long-term supply reliability and regulatory compliance across all three options.

Frequently Asked Questions (FAQ)

Q: Are RSMF2JB82R0, RSMF2JT82R0, and RSF2JT82R0 electrically interchangeable?

A: Yes. All three parts share identical electrical specifications: 82 Ohms resistance, ±5% tolerance, 2W power rating, metal oxide film composition, ±200ppm/°C temperature coefficient, and -55°C ~ 235°C operating range. They are direct electrical equivalents.

Q: What is the primary difference between these substitute parts?

A: The primary differences are packaging format and physical dimensions. RSMF2JB82R0 uses Bulk packaging, RSMF2JT82R0 uses Cut Tape, and RSF2JT82R0 uses Tape & Reel. Physical dimensions vary: RSMF series measures 0.177" Dia x 0.433" L (4.50mm x 11.00mm), while RSF2JT82R0 measures 0.217" Dia x 0.591" L (5.50mm x 15.00mm).

Q: Can RSF2JT82R0 be used in place of RSMF2JB82R0 in a circuit board design?

A: Electrical substitution is valid. However, the larger physical dimensions of RSF2JT82R0 (0.217" Dia x 0.591" L versus 0.177" Dia x 0.433" L) must be verified against PCB layout constraints and mechanical clearance requirements before implementation.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Which packaging format should I select for automated assembly?

A: RSF2JT82R0 (Tape & Reel) and RSMF2JT82R0 (Cut Tape) are both suitable for automated assembly equipment. Tape & Reel is optimized for high-volume production, while Cut Tape accommodates moderate-volume operations.
